Description

The present invention relates to a two-wheeled component, in particular for an at least partially muscle-operated bicycle or bicycle and a bicycle with such a two-wheeled component and a method for operating a two-wheeled vehicle component.

Modern bicycles and especially high-quality sports bicycles can today be equipped with a variety of components from the field of electronics and information technology. Such components are for. GPS-capable navigation devices, controllable shock absorbers, and sensors for monitoring performance parameters of the athlete, e.g. Pulse or heart rate sensors. In addition, a screen is often provided for displaying the measured data and digital maps.

Corresponding interfaces also allow the connection of various electronic devices on the bike with a smartphone. For example, the personal settings on the bike can be entered and changed and the stored performance values shared with training partners and friends. On the other hand, using such interfaces makes it particularly easy to take over new routes in an unknown terrain or improved setup for the shock absorbers of other cycling.

The adjustment, monitoring and evaluation of the technical components on the bike and the monitoring of the training condition of the athlete are very simple and reliable possible by such electronic systems.

Likewise, they also offer recreational athletes the opportunity to refer to the attitudes and experiences of experts and they can even without a coach to get a meaningful overview of the personal fitness state.

Due to the increasingly compact and efficient computer systems and control units, more and more data can be collected, processed and stored with the electronic components on the bicycle. In addition, the necessary sensors are becoming more and more cost-effective.

However, the weight and the size of such components play a major role in the bicycle sector and especially in the cycling sector. Thus, in most cases, special adaptations and, as a rule, new developments are necessary in order to implement electronic components, which are used in other areas without major difficulties, in the bicycle sector. Thus, there is a high demand in the bicycle sector for technical developments in order to be able to fully exploit the possibilities of electronic control and information systems and make them optimally available to the cyclist.

It is therefore the object of the present invention to provide a two-wheeled component which provides information which can be used to improve the handling of bicycles.

This object is achieved by a two-wheeled vehicle component having the features of claim 1, and by a bicycle having the features of claim 8 and by a method having the features of claim 9. Preferred features are the subject of the dependent claims. Further advantages and features will become apparent from the general description of the invention and the description of the embodiments.

The two-wheeled component according to the invention is provided for a bicycle, which is operated by a driver at least partially by a driver. In this case, the two-wheeled component comprises at least one control device and at least one sensor device. The sensor device comprises at least one sensor. The sensor is suitable and designed to detect at least one characteristic of the position of the driver relative to the two-wheel component size. The sensor device is suitable and designed to recognize at least two different driver positions as a function of the detected variable. In addition, the sensor device is suitable and designed to provide the recognized driver positions of at least one or at least one control device.

The two-wheeled component according to the invention has many advantages. A considerable advantage is that the position which the driver takes on the bicycle is reliably detected by a sensor device. The assumed driver position is an important information with which the handling of the bicycle can be significantly improved. For example, based on the driver's position, a statement can be made about how much effort the driver uses to master the current route section. In addition, the driver's position can be used to detect a current load or utilization of the bicycle and / or the driver.

A further advantage is that the information about the driver's position of the control device is provided. Starting from the control device, the information can then either be used by the control device itself, or it serves as an interface and outputs the Information to other devices and components further. For example, the recognized driver positions can be stored in a memory device and compared with recorded GPS data. This allows the driver to easily and conveniently check whether he has taken the optimum position on his bike at the appropriate points in a course.

A characteristic quantity for a position of a driver is the position of the driver relative to the bicycle. The position of the driver may be determined relative to one or more parts of the two-wheeler component. For example, the position of the driver or at least one characteristic variable relative to the sensor device can be determined.

In a particularly preferred development, the control device is suitable and designed to control at least one shock absorber device, taking into account a driver position provided by the sensor device. The shock absorber device may comprise, for example, at least one suspension fork and / or at least one rear wheel damper. The shock absorber device may have shock absorbers for the chassis and / or shock absorbers separately from the chassis. The latter shock absorbers are, for example, shock absorbers for the steering area such as steering dampers and / or for the saddle area such as height-adjustable and / or damped seatposts.

Such control of the shock absorber device as a function of the driver's position is particularly advantageous, since different weight distributions also occur at different driver positions. Due to the position detection, the shock absorber can now be optimally adjusted to the respective weight distribution. In addition, weight shifts due to position changes can be reacted with an adaptation of the shock absorber device while driving.

Preferably, the shock absorber device has at least one damper device. In particular, the damper device comprises at least one first damper chamber and at least one second damper chamber. The damper chambers are preferably coupled to one another via at least one at least partially controllable by the control device damping valve. Damping valve and control device are designed so that at least one damping property of the damper device can be influenced by a signal of the control device. Such control of the shock absorber device by means of a controllable damper valve of a damper device is particularly reliable.

The term control is understood in the context of the present invention in preferred developments also a scheme. Such a regulation can be active or passive. It may also be provided a control of the damper device independently of the control of the damping valve. For example, an additional chamber of the spring device can be switched or switched off.

Particularly preferably, at least one field generating device is assigned to the damping valve. The field generating device is designed in particular controllable by the control device. The field generating device is provided for generating and / or controlling a field strength in at least one damping channel of the damping valve. For example, an electrical coil may be provided for this purpose.

In particular, a field-sensitive rheological medium is provided at least in the damping channel. Such a trained damper device provides a particularly reliable and rapid adaptation of the damping properties in response to the detected driver position. In addition, a control of the damping valve without the use of motorized moving parts is possible. Furthermore, a high resolution adjustment of the damper properties is possible. For example, depending on the detected driver's position, certain characteristic curves stored in a memory device are retrieved, according to which the adaptation of the damper characteristics takes place. Such a damper device requires little energy and is fail-safe, which is important for safety when the battery fails or a defect occurs. These are important features and benefits for using on a bicycle.

Particularly preferably, a magnetorheological medium and in particular a magnetorheological fluid is used as the rheological medium. In particular, the resulting viscosity of the fluid or the shear stress is influenced by the intensity and strength of the magnetic field built up by the field-generating device.

The shock absorber device may comprise at least one spring device. The spring device has, in particular, a spring property that can be set by at least one actuator. The control device is preferably suitable and designed to control the actuator as a function of the detected driver position. The adaptation of spring characteristics of the shock absorber device represents a further advantageous use of the information about the driver's position. By adjusting the spring characteristic is then, for example, an optimal rebound of the shock absorber guaranteed when the driver shifts his weight in the direction.

The shock absorber device may have at least one first damper device associated with the front wheel. It is also possible that at least one second damper device assigned to the rear wheel is provided. The first damper device is, for example, a suspension fork. The second damper device may be formed, for example, as a rear-wheel damper. In this case, damper devices can be provided which are not designed to be controllable by the control device. Preferably, both the first and the second damper device are controllably formed by the control device.

In a particularly preferred development, the control device is suitable and designed to independently adjust the first damper device and the second damper device. This has the advantage that a different adjustment of the front and rear damper is possible, which enables optimal driving characteristics, especially in driver positions with one-sided weight transfer. It is also preferred that the suspension characteristics can be changed and, in particular, controlled.

Particularly preferably, the sensor device is suitable and designed to recognize at least two driver positions. The driver positions are taken from a group of driver positions that include at least the following seating positions: sitting normally, leaning forward, standing above the bottom bracket, leaning backwards, leaning forward or standing in a sprint position and at least one downhill position. Such driver positions are very often taken in cycling and are characteristic of certain driving conditions. Therefore, their detection is particularly meaningful.

In particular, at least three and preferably at least four or more driver positions can be recognized by the sensor device. Particularly preferably, all the aforementioned driver positions are recognizable. It is also possible and preferred that the sensor device can recognize further driver positions, for example up to ten or twenty or more driver positions. It may also be a position characterizing the driver's movement recognizable, such. B. a saddle. It is also possible and preferred to recognize at least one recurring sequence of driver positions. In particular, if other parameters such as terrain, speed, heart rate, cadence, cadence, torque, gear adjustment of the circuit, etc. monitored and / or detected. Such information can be useful, even if the system is responding in real time.

In particular, the sensor device is suitable and designed to recognize further gradations of the aforementioned driver positions. The distinction between different driver positions can be done discretely, for example by predetermined thresholds. If, for example, a threshold value is exceeded, this leads to the exclusion and / or recognition of a specific driver position. The adjustment of the damping properties then takes place in particular according to the settings which are assigned to the recognized driver position. However, it is also possible that there is no determination of discrete driver positions, but an adaptation of the damper properties is carried out on the basis of measured or calculated position values. The control of the damper device can also be done discretely or steadily.

The sensor device has in particular at least one sensor. The sensor is particularly adapted and adapted to sense a pressure or force caused by at least a portion of the driver's body. For example, the body weight-related stress (pressure and / or force) can be detected on the saddle. It is also possible to record the load (pressure and / or force that is generated by the bracing on the handlebars.) A load such as a pressure or a force in this sense is detected in particular by means of pressure sensors, force sensors and / or strain sensors Such sensors have the advantage that the respectively assumed position is recognized on the basis of a characteristic weight distribution.

The sensor device is preferably suitable and designed to recognize the driver position as a function of a threshold value of the detected load (pressure and / or force, etc.). For example, it can be detected by a drop below the pressure or the force on the saddle that there is currently no sedentary posture. It is also possible that several load sensors (pressure or force sensors) are provided in the handlebar area. This can be determined at which point of the handlebar area, the driver is supported, and thus whether the driver assumes a forward or backward leaning position.

Preferably, the sensor device is suitable and designed to recognize the driver position as a function of a temporal change of the detected load (pressure / force). Such an embodiment has the advantage that not of Absolute values must be assumed and thus a seated position of the driver is recognizable without knowing his body weight. For this purpose and for further developments, the control device can be designed to be adaptive and, for example, comprise a learning algorithm in the sense of a fuzzy logic or a principle of a neural network or the like. This makes it possible, for example, to determine on the basis of temporal pressure / force changes to one or more sensors, when the driver sits in the saddle maximum or is leaning on the handlebars maximum.

Preferably, the sensor is adapted and adapted to detect a force acting on at least one component of the bicycle force. A force sensor used for this purpose as a sensor can be embodied in particular as a weight sensor and / or strain sensor and can comprise at least one strain gauge and / or at least one piezo. The output signal of the force sensor is evaluated. Thus, for example, the current weight load on the respective component can be determined via a force sensor on the seat post, the handlebar, the stem or the pedals, etc.

Preferably, the sensor is adapted and adapted to detect a force acting on a drive of the bicycle or an acting moment. For this purpose, the sensor may be arranged, for example, in the region of the bottom bracket and / or the pedals and / or a locking system of the pedals. It is also possible that at least one sensor is suitable and designed to detect a force acting on a component which serves as an abutment for the driver during the provision of the driving force. Such a component is, for example, the handlebar and / or the stem and / or a locking system of the pedals and / or the seat post or the saddle.

Such sensors are particularly suitable for detecting the driver's position, since the forces acting here are particularly characteristic of certain driver positions. Particularly preferably, a combination of two or three or more sensors is provided at different locations, wherein the signals from the control device are at least partially integrated.

The sensor device comprises in particular at least one pressure sensor and / or force sensor and / or weight sensor and / or torque sensor and / or strain sensor and / or acceleration sensor and / or displacement sensor and / or sensors for angle or inclination measurement. Particularly preferably, the sensor device comprises at least one sensor with a strain gauge. Such a sensor is reliable and inexpensive and also has a very small footprint.

In particular, at least one sensor is provided, which is connected to at least two components of the bicycle, which change their position relative to one another depending on the driver's position. In particular, at least one force sensor and / or strain sensor is provided between the two components. The sensor is particularly suitable and designed to detect the change in position of the two components. In addition, the sensor device is preferably suitable and designed to recognize the driver position as a function of the detected change in position. For example, such a sensor may be provided on an adjustable seat post, which is fully or partially automatically adjustable while driving. Such a detection of the position of an adjustable seat post can be used advantageously for the detection of the driver position, since the adjustment is usually accompanied by a change in position. It is also possible that the seatpost is adjusted according to the sensor values.

Particularly preferably, the sensor detects the position of two mutually movable components of the shock absorber device. The advantage of such a configuration is that the shock absorber device usually has such components and these are moved by weight shifts accordingly. Such a sensor can therefore be mounted here particularly inexpensively. For example, the sensor can be arranged on the telescopic components of a suspension fork or a rear shock absorber. Such a sensor is provided in particular in combination with other sensors for position detection, since a distinction between a movement due to chassis impacts or due to changes in driver position can thus be ensured.

In an advantageous embodiment, the sensor device is suitable and designed to detect the distance of at least part of the body of the driver to a sensor. As sensor, for example, an ultrasonic sensor may be provided. It is also possible to use optical sensors and cameras or at least one infrared sensor. At least one radar sensor can also be provided. Optical sensors can also perform recognition of the driver's position via image recognition and image size evaluation. With stereo cameras or two separate optical sensors, a three-dimensional detection can also be performed. The aforementioned sensors are particularly suitable for transmitting the respective signals and for receiving the signals reflected by the body of the driver. Preferably, the sensor device is to suitable and trained from the detected distance to the sensor to determine the driver's position. It is also possible that the driver carries at least one sensor on his body. Preferably, passive sensors are attached to the clothing. For example, passive components for contactless exchange by means of near-field communication (NFC) can be provided in or on the clothing.

Such embodiments allow a particularly high-resolution recognition of the driver's position. For example, it can be recognized how far the driver is leaning with his upper body in the direction of the top tube or the handlebar. Accordingly, the setting of the damper device can be adapted particularly precisely to the assumed driver position, so that the overall result is a very good coordination of chassis damping and actual driver position.

A possible embodiment provides that the sensor device comprises at least one sensor for detecting a variable which is characteristic of the spatial position of the bicycle. For the purposes of the present invention, the term "spatial position" particularly refers to the orientation of the bicycle in relation to the horizontal and not to the possibly inclined ground on which the bicycle is located. The horizontal is defined by a plane that is perpendicular to the gravitational acceleration. Accordingly, the spatial position can also be defined relative to the vertical parallel to the direction of gravitational acceleration, which in turn is perpendicular to the horizontal plane.

For detecting the spatial position, in particular at least one position sensor and / or at least one inclination sensor or the like is provided. In this case, the sensor device is in particular suitable and designed to recognize at least two different spatial positions as a function of the detected variable. In addition, the sensor device is preferably suitable and designed to provide the detected spatial position of the control device. The recognition of the spatial position represents a particularly advantageous supplement to the detection of the driver's position. In addition, a comparison of the spatial position with the detected driver position by the control device allows an even more accurate determination of the driver's position. For example, such an incorrectly determined due to very steep uphill or downhill driver position can be reliably counteracted.

In particular, the sensor device is suitable and designed to recognize at least two spatial positions which are taken from the following group of spatial positions: horizontal, upward, steep upward, downward, steep downward. It can also be provided more space. It is also possible that the spatial positions have more gradations. For example, discrete spatial positions may be provided. It is also possible a steady transition from one spatial position to the next. Also preferred is a definition about the angle to the horizontal.

In a further particularly preferred embodiment, the control device is suitable and designed to control the shock absorber device as a function of both the driver's position and the spatial position. Due to the consideration of both parameters, the shock absorber device can be adapted particularly well to the prevailing conditions. In this case, the consideration of the driver's position and the spatial position can take place equally. It may also be provided in the damper setting, a priority for the driver's position or the spatial position. For example, a map-like control is provided, which results in a corresponding adjustment of the damper device on the basis of a combination of recognized driver position and detected spatial position.

In all embodiments, it is particularly preferred that the two-wheeled component comprises at least one storage device. Preferably, data is stored in the memory device, which is detected by the sensor device and / or derived from the sensor data. In this case, in addition to the data about the detected driver positions, in particular also time data about the recording time and / or GPS data for the detection time of the data and / or other route data can be stored. Preferably, data about the driver's position is not stored. Preferably, data about the shock absorber device or its current position and setting of the damper device are also stored in the memory device. This allows trips to be analyzed. This serves e.g. the manufacturer for analysis or allows the user to better tune e.g. the spring hardness and determine if the air pressure is correct. The user can receive a corresponding feedback. Also, the user can later evaluate the stored data and compare it with data from other users.

All or part of the data may be automatically transmitted to the Internet and / or to a smartphone, smartwatch, Smartdevice or other computer on a regular or on-demand basis. When transferred to the Internet, they are preferably stored on a memory in the Internet (Internet storage, cloud).

In all further embodiments, it is preferred that the two-wheeled component a gearshift, hereinafter referred to simplified circuit includes, or that such a gearshift or circuit of the two-wheel component is assigned. The circuit is preferably designed as a derailleur, but may also include a hub gear or a planetary gear or other gear such as Vario gear or spur gear, etc. Preferably, the control means is adapted and adapted to set a transmission ratio of the circuit. In particular, the control device is suitable and designed to control the circuit in dependence on a provided driver position.

As a result, the shift gear can be changed depending on the driver's position. Preferably, further sensor data are taken into account for this purpose. In particular, the driving speed of the bicycle and / or it can be considered a cadence at the bottom bracket and / or a spatial position and in particular the current slope. So z. B. directly one or two gears are switched down when the driver gets up at an uphill to change in the Wiegetritt. Correspondingly, conversely, it is also possible to downshift when the driver sits down and / or the cadence decreases.

The method according to the invention is suitable for operating a two-wheeled component which is provided for a bicycle which is operated at least partially by a driver. In this case, at least one parameter that is characteristic of the position of the driver relative to the two-wheeler component is detected. Depending on the detected size at least two different driver positions are detected. The recognized driver positions are provided to a controller.

The method according to the invention has the advantage that the driver position is recognized and made available to a control device. The attitude of the rider on the bicycle is an important piece of information for judging the driving technique. In addition, knowing the rider's position, the suspension and other components on the bicycle can be more accurately adjusted, so that the handling of the bicycle improves overall.

Particularly preferably, a two-wheeled component is used in the method according to the invention, as has been described above.

Preferably, at least one damper device of a shock absorber device is controlled by a control device. In this case, in particular with a controllable field-generating device, a field strength in at least one damping channel of a damping valve of the damper device (targeted) is set to selectively influence a field-sensitive rheological medium in the damping channel.

Particularly preferably, a damper device is controlled and / or regulated on the basis of the recognized driver position, so that at least one damping property of the damper device can be influenced as a function of the driver's position. It is also preferable that at least one spatial position of the bicycle is recognized and considered together with the driver's position for controlling the damper device. It is also preferred that the damper device comprises a controllable field-generating device and has a field-sensitive rheological medium.

Preferably, damping of at least one damper device associated with a front wheel of the bicycle as well as the damping of at least one damper device associated with a rear wheel of the bicycle are set softly and / or set to a basic setting as at least one consequence of a recognition of a seated driver position and a substantially horizontal spatial position of the bicycle.

In particular, damping of at least one damper device associated with a front wheel of the bicycle and the damping of at least one damper device associated with a rear wheel of the bicycle are set softly as at least one consequence of detection of a standing driver position and a substantially horizontal position of the bicycle.

Preferably, damping of at least one damper device associated with a front wheel of the bicycle as well as damping of at least one damper device associated with a rear wheel of the bicycle are set taut as at least one consequence of detection of a seated driver position and upwardly inclined attitude of the bicycle.

It is preferable that, as at least one consequence of detection of a standing driver's position and a bicycle's upward sloping attitude, cushioning of at least one damper device associated with a front wheel of the bicycle becomes soft and cushioning at least one damper device associated with a rear wheel of the bicycle is taut.

In particular, as at least one consequence of a detection of a central driver position and a downwardly inclined attitude of the bicycle, a damping of at least one damper device associated with a front wheel of the bicycle and the damping of at least one damper device associated with a rear wheel of the bicycle are set soft.

Particularly preferred as at least one consequence of a recognition of a rearward driver position and a steeply downward sloping attitude of the bicycle cushioning at least one damper device associated with a front of the bicycle tighter and the attenuation of at least one damper device associated with a rear of the bicycle soft or soft set.

In a preferred development of the method, the damping of at least one damper device associated with a front wheel and, in particular, a suspension fork and the damping of at least one damper device assigned to a rear wheel of the bicycle and, in particular, of a rear wheel damper, are set soft in the direction of recognition. It is possible a different soft setting the damping for front and rear. It may also be provided as it were soft setting the damping for front and rear. The adjustment can also take place in that the damping is brought into at least one default setting. For example, a damper setting for normal driving may be provided for this purpose.

Such adjustment is preferably in response to the detection of a seated driver's position. Such adjustment is preferably also in response to a substantially horizontal spatial position of the bicycle, z. B. when driving in flat terrain. Here, a substantially horizontal spatial position is preferably also given when the bicycle has some degrees or 10 degrees or even 20 degrees or more inclination to the horizontal. Such space situations often occur during cycling, without the driver having to change his posture and thus an adaptation of the damping would be necessary. Such an adjustment is particularly preferably made when both a seated driver's position and a horizontal position in space are detected. As a result, on the one hand, the driver's power for the drive can be utilized very well and, on the other hand, reliable damping can be ensured.

How soft and / or taut a damper adjustment as a result of the detection of the driver's position is preferably dependent on at least one default setting of the damper device in all embodiments. For example, such a damper setting may depend on the weight of the driver and / or a specification regarding the terrain to be traveled. As a result, for example, of a shock, a different damper setting can be made, in particular, temporarily.

In a further preferred embodiment of the method, the damping of the front wheel associated with the damper device is adjusted taut. The damping of the rear wheel associated with the damper device is particularly soft.

Such a setting is preferably carried out in response to the detection of a standing and in particular a forward leaning driver position, for. B. a saddle. Such a setting is preferably also in response to a substantially horizontal spatial position of the bicycle. Such an adjustment is particularly preferably made when both a stationary driver position and a horizontal spatial position are detected. As a result, a collapse of the fork is well counteracted and at the same time a reliable grip on the rear wheel is achieved.

An advantageous embodiment of the method provides that the damping of the front wheel associated damper device and the damping of the rear wheel associated damper device are set taut. It is possible here a differently tight adjustment of the damping for front and rear. It can also be provided as quasi a tight adjustment of the damping for front and rear.

Such adjustment is preferably in response to the detection of a seated driver's position. Such adjustment is preferably also in response to an upwardly inclined spatial position of the bicycle, z. B. when driving in ascending terrain. Here, the bicycle is preferably inclined by 10 degrees or 15 degrees or 25 degrees or more to the horizontal. Such an adjustment is particularly preferably made when both a seated driver's position and an upwardly inclined position in space are detected. This significantly reduces swinging of the front and rear shock absorbers so that the driving force can be optimally used.

In a further advantageous embodiment, the damping of the front wheel associated damper device is set soft and in particular very soft. It is also possible to lower a suspension fork on the front wheel. The damping of the rear wheel associated with the damper device is preferably set taut.

Such an adjustment is preferably made in response to the detection of a driver's position greatly bent forward or over the handlebar. Such a setting is preferably also in response to an upward and in particular steeply inclined upward position of the bicycle, z. B. when driving in high terrain. Here, the bicycle is preferably inclined 15 degrees or 25 degrees or 35 degrees or more to the horizontal. Such an adjustment is particularly preferably made when both a forward-leaning, seated driver position and a steeply upwardly inclined spatial position are detected. So a good power transmission is achieved in conjunction with a significantly improved traction.

In a likewise preferred development, the damping of the damper device assigned to the front wheel and the damping of the damper device assigned to the rear wheel are set soft. It is possible a different soft setting the damping for front and rear. It may also be provided as it were soft setting the damping for front and rear. Also possible is a basic setting or a softer setting than the default setting.

Such adjustment is preferably in response to the detection of a central driver position. The driver can stand or sit here. A central attitude is especially present when the center of gravity of the driver is approximately centered between the front wheel and the rear wheel. Such adjustment is preferably also in response to a downwardly inclined spatial position of the bicycle, z. B. in a downward journey. Here, the bicycle is preferably inclined 10 degrees or 15 degrees or 25 degrees or more down to the horizontal. Such a setting allows a comfortable downhill with an optimal grip.

In another preferred embodiment, it is provided that the damping of the front wheel associated damper device is set tighter. The damping of the rear wheel associated damper device is particularly soft and preferably set very soft.

Such adjustment is preferably in response to the detection of a rearwardly leaning driver position. The driver can stand or sit here. In particular, the center of gravity of the driver is shifted in the direction of the rear wheel. Such adjustment is preferably also in response to a strong downwardly inclined spatial position of the bicycle, z. B. in a downhill in steeply sloping terrain. Here, the bicycle is preferably inclined 15 degrees or 25 degrees or 35 degrees or more down to the horizontal. By such a tighter attitude z. As the fork a particularly good support effect is achieved, so that an undesirable sagging of the suspension fork when driving downhill is avoided.

The bicycle according to the invention is at least partially muscle-operated. In this case, at least one two-wheeled component is provided, which is designed like the two-wheeled component according to the invention or one of its developments. Such a bicycle allows both the recreational and the competitive athletes improved handling, since it also has all the advantages of the two-wheeled component according to the invention.

The cited cases and positions are not exhaustive, but represent only a memorable selection. There are other load cases, which are considered accordingly. Basically, the chassis can be adjusted accordingly.

Both the front wheel 111 as well as the rear wheel 112 are equipped with spokes and can dispose of disc brakes.

The control of the shock absorbers 100 and other two-wheeled components can be made depending on various parameters and also based on sensory data. Optionally, the spring and / or damping properties of the seat post can be adjusted. It is possible that with the central control device 60 Also, the (chain) circuit for setting various translations can be controlled.

In addition, here each shock absorber 100 at least one control device 46 on a replaceable provided electronic unit. The electronic units may each have separate battery units. However, a power supply by the central battery unit is preferred 61 or the support or operation by a dynamo or the like.

The suspension control 300 and the central controller 60 are via operating devices 150 served. There are two control devices 150 provided, namely an actuating device 151 and an adjustment device 152 , The actuating device 151 has mechanical input units 153 at the lateral ends or near the lateral ends of the handlebar 116 on. The adjustment device 152 can be designed as a bike computer and also on the handlebars 116 be positioned. But it is also possible that a smartphone 160 , or a tray or the like as an adjustment 152 is used and stored for example in the pocket or in the backpack of the user, if no change in the settings is made.

The actuating device 151 here includes three mechanical input units as controls 154 . 155 . 156 to operate the shock absorber 100 , It is possible that for the suspension fork 114 an actuator 151 at one end of the handlebar 116 is arranged and at the other end of the handlebar a corresponding further actuator 151 for the rear wheel bumper 115 is provided. It is also possible that both shock absorbers with an actuator 151 be controlled synchronously. It is also possible that at a lateral end of the handlebar 116 an actuator with, for example, six different controls for adjusting both shock absorbers 100 is arranged.

The actuating device 151 is considerably more robust and resistant than the operating device 152 and gets stuck here on the handlebar 116 anmontiert. The individual controls designed as pushbuttons or buttons 154 to 156 each have protection according to IP54 or better IP67 DIN EN 60529 on. There is protection against impacts of at least IK06 according to DIN EN 622622 in front. This is the controls 154 to 156 sufficiently protected in normal operation, so that damage to the controls during operation, even in normal bumps or the like does not occur. In addition, the robust controls provide 154 to 156 for reliable operation even on downhill rides or the like.

The adjustment device 152 whereas, for example, clipped on the handlebar or which remains in the user's pocket or backpack, offers considerably more and / or clearer adjustment options and can be used to display a displayed damper characteristic 10 in at least two or more areas 161 . 162 etc. to adjust the desired damper properties. The adjustment device 150 indicates a display or a display 49 on and can also data 48 output, for example, affect the damper settings or contain data on the current travel speed, etc. In addition to or instead of changing the damping can be on the adjustment 150 and 152 also at least one spring characteristic or the characteristic of the suspension are changed. In particular, the spring hardness during compression and rebounding can be influenced. In addition, if necessary, the rest position can be adjusted. For example, lowering the suspension fork 114 be made on (steep) mountain rides, reducing the angle of inclination of the bike 200 is reduced.

the display 49 is especially as a graphic control unit or touch screen 57 executed, so that the user, for example, a damper characteristic shown 10 Touch with your fingers and change them by dragging. As a result, from the solid line shown damper characteristic 10 by touching at one or more points 170 to 175 the damper characteristic shown 90 be generated, which is now available for vehicle control 300 is used. The change of damper characteristics 10 . 90 is also possible while driving. Here not only the damping is changed, but it can also be changed at the same time or just the suspension.

The adjustment device 152 can also serve as a bike computer and display information about the current speed, as well as the average speed and / or the day, tour, lap and total kilometers. It is also possible to display the current position, the current height of the driven route and the route profile and also a possible range under the current damping conditions.

The central control device shown here 60 is part of the two-wheeled component according to the invention 401 , Furthermore, the two-wheeled component includes 401 a sensor device 403 with a plurality of sensors 404 , However, in other embodiments, the sensor device may also comprise only a single sensor or only two or three sensors. The sensors 404 capture here a size which is characteristic of the position that a rider on the bike 200 occupies. The two-wheeler component shown here 401 can therefore be operated particularly advantageous according to the inventive method. It is possible ultrasonic sensors 424 , Infrared sensors 434 and / or position sensors 444 and other sensor types as sensors 404 use.

The sensor device 403 determines the driver position based on the data values transmitted by the sensors. The communication between sensor device 403 and the associated sensors 404 can be done wirelessly, for example. The sensors 404 but also via corresponding lines with the sensor device 403 be connected. In addition, the sensor device 403 also be operatively connected to other control devices of the bicycle. The recognized driver positions are detected by the sensor device 403 the central control device 60 made available.

The for the control device 60 Information about the driver's position provided can be used in a variety of ways. For example, the driver positions may be from a storage device 418 be retrieved and deposited in this. Preferably, an interface is provided, with which the user the storage device 418 can read, for example, with a smartphone 160 ,

In conjunction with parallel recorded GPS data, the user may, alone or in conjunction with other users or a trainer z. B. after the exit quietly understand when and where he has assumed a particular sitting position on his route traveled and whether this position was also the appropriate for the particular driving maneuver. In addition, an incorrect posture or an unfavorable setting of the bicycle geometry can be detected by monitoring the driver's position. By optimizing the driver's position, an improvement of the power delivery is possible and with longer tours, the fatigue, for example, the wrists can be avoided.

To detect the driver's position, a number of sensors 404 be provided, some of which attachment possibilities are shown here by way of example. In fact, however, significantly fewer or even more sensors can be used 404 on a bicycle 200 be provided. So can sensors in the area of the saddle 117 and / or the seatpost may be provided, with which it can be detected whether the driver sits in the saddle or with what proportion of his body weight, the driver is supported in the saddle. Such a saddle-mounted sensor is for example with a strain gauge 414 educated. Such sensors are inexpensive and can be installed to save space and almost inconspicuously below the seat.

To detect whether the rider rests fully in the saddle or possibly rests on other areas of the bike, more sensors can 404 be provided on other components. It is also possible that the driver inputs via an input device data about his body weight and / or his body size, that of the sensor device 403 can be used in the determination of the driver's position.

Other sensors 404 For example, in the area of the handlebar 116 and / or the stem be provided. With such sensors, information can be obtained as to whether the driver is leaning forward leaning on the handlebars or perhaps even leaning backwards on the handlebars. In conjunction with the aforementioned sensors on the saddle or on the seat post so can be done very accurate determination of various driver positions. This can be supplemented by sensor data for a torque detection on the bottom bracket or the force acting on the pedal when pedaling or pulling a shoe coupled to the pedal.

It can also be provided sensors which are arranged in the region of the drive. For example, sensors may be mounted on the crank and / or on the pedals in the area of the bottom bracket. Particularly advantageous information can also be obtained by means of sensors which are connected to the shock absorber device 100 are arranged. For example, the damper device 1 a fork 114 and / or a rear-wheel damper 115 with a sensor 404 be equipped. For example, it can be detected how far the damper device is loaded or retracted while driving.

Particularly meaningful is, for example, a comparison of the sensor values of the suspension fork with the sensor values of the rear wheel damper. If different damper loads are present, it is possible to draw conclusions about a driver's position leaning forward or backward. It should be noted, however, that shock loads not caused by shocks are used to detect the driver's position. This is possible z. B. on the consideration of a measurement period and / or a plurality of measurement data in chronological order. For example, the load can be deduced using a moving average, edge filter or low-pass filter or by using other intelligent filters, so that dynamic influences can be filtered out by shocks and a reliable measure of the load can be output.

Preferably, the already in the damper devices 1 provided sensor used for the detection of the driver's position. For example, the previously described damper sensor 47 be used in such a way. In addition to the damper sensors and sensors for monitoring or control of a spring device 26 be used for the driver position detection. The spring device 26 can be designed as a gas spring and a positive chamber 27 and a negative chamber 28 include.

Other sensors 404 For example, they can be provided on the wheels and designed there as air pressure sensors. By balancing the sensor values, the driver can shift his weight. It can also be provided a sensor with which the position of at least a part of the body of the driver can be directly sensed. For example, an ultrasonic sensor and / or an infrared sensor may be provided in the region of the top tube or the handlebar. So it can be determined how far the driver leans forward. In addition, sensors on the bike can 200 be provided, which interact with sensors on the clothing of the driver. For example, in the jersey or the gloves passive sensors may be incorporated, the position of which is easily detectable by the sensors mounted on the bicycle.

In addition is the bicycle shown here 200 with a sensor 444 for detecting the spatial position of the bicycle 200 equipped. With such a room position sensor 444 For example, it can be determined how strong the bike is 200 is tilted forward or backward or sideways. Information about the location of the bicycle 200 can be used, for example, for verification of the driver's position, since weight shifts in addition to a position change can also be caused by a large slope or a large slope. In addition, knowing the spatial position and an improved setting of the shock absorber device 100 possible, because depending on the spatial position a larger load rests on the front wheel or rear wheel.

2 shows a schematic representation of the suspension control 300 and the communication links of some involved components. The central control device 60 can be wired or wirelessly connected to the individual components. For example, the control device 60 be connected to the other components via WLAN, Bluetooth, ANT +, GPRS, UMTS, LTE or other transmission standards. Optionally, the control device 60 via the dotted connection to the Internet 53 be wirelessly connected.

The control device 60 is with the battery unit 61 connected. Furthermore, the control device 60 with a sensor device 47 or connected to multiple sensors. At least temporarily, the controls are 150 namely the actuating device 151 and the adjustment device 152 wired or wireless with the controller 60 coupled. The actuating device 151 is preferably wired to the controller coupled, but may also be wirelessly connected and have a separate battery such as a button cell or the like.

The robust built-up actuator 151 has at least one mechanical input unit 153 in the form of a switch or the like, about a Umstellbefehl to the control device 60 to output for switching at least one damper and / or spring property. This may, for example, be the activation of a lockout or the activation of a rocker suppression or the adjustment of the damper hardness and / or the spring stiffness. Preferably, a separate control knob or the like is provided for each of these properties. But it is also possible that a single mechanical input unit 153 is used to switch the individual options. The mechanical input unit 153 or a mechanical input unit may serve to alter the suspension characteristics. For example, the suspension fork can be lowered and the rear shock absorber adapted accordingly.

The adjustment device 152 has a graphical user interface such as a touch-sensitive screen and can display on display among others 49 the current damper characteristic 10 represent. For example, by touching and pulling the damper characteristic at individual points 169 . 170 . 171 . 172 and 173 can the damper characteristic 10 basically be moved laterally or in height. Preferably, the individual points 169 . 170 . 171 . 172 or 173 etc. linearly connected. Also possible is a dynamic connection of the individual points via automatically generated splines, so that a rounded damper characteristic exists.

The control device 60 is via network interfaces 54 or radio network interfaces 55 with control devices 46 the shock absorber 100 connected to the front wheel and the rear wheel. The possibly on each shock absorber 100 provided control device 46 takes care of the local control and can each have a battery or with the central battery unit 61 be connected. It is preferred that the control of both shock absorbers via the control device 60 he follows.

Preferably, each shock absorber 100 at least one sensor device 47 assigned to relative movements between the components 101 and 102 to capture and in particular a relative position of the components 101 and 102 relative to each other. The sensor device 47 may be formed as a displacement sensor or include such. Based on in the storage device 45 stored damper characteristic 10 of the shock absorber 100 After determining a characteristic value for the relative speed, the associated damping force and a suitable spring force is set. A suitable spring force can be determined by the weight of the driver. For example, by automatically determining the SAG position after a driver has touched down, the weight of the driver can be deduced. From the Einfederungsweg when putting the driver on the bike can be concluded that a suitable air pressure in the fluid spring or gas spring, which is then set or approximated automatically immediately or in the course of operation.

In 2 is the tax cycle 12 shown schematically in the storage device 45 is stored and in the control device 60 deposited or programmed. The control cycle 12 is performed periodically during operation and in particular continuously periodically. In step 52 is with the sensors 47 a current relative movement or relative speed of the first component 101 to the second component 102 detected. From the values of the sensor 47 or the sensors gets in step 52 derived a characteristic value which is representative of the current relative speed. In the step, the associated damping force to be set is then subsequently determined from the current or determined characteristic value taking into account the predetermined or selected damper characteristic curve 84 derived. From this, a measure of the currently set field strength or current intensity is derived, with which the damping force to be set is at least approximately achieved. The measure can be the field strength itself or z. B. indicate the current at which the set damping force is at least approximately achieved.

In the following step 70 the currently set field strength is generated or the corresponding current to the electric coil device 11 created as a field generating device, so that within a single cycle or a time period of the control cycle 12 the damping force is provided, which is provided at the selected or predetermined damper characteristic to the current relative speed of the first component to the second component. Then the next cycle starts and it is step again 52 carried out. In each cycle, or at certain time intervals or in certain events, the position or the spring force of the spring device 26 checked. This is with the fluid spring 260 (see. 3a and 3b ) the strength of the spring force of the positive chamber 270 and the strength of the spring force of the negative chamber 280 checked or determined. Will be a harder fluid spring 261 desired, for example, the second positive chamber 272 be turned off so that the fluid spring 260 gets a steeper course of the spring force. Or it becomes the volume of the negative chamber 280 changed or it becomes a position 292 the compensation device 290 changed.

In the suspension control shown here 300 is also the two-wheeler component 401 with the sensor device 403 and the associated sensors 404 implemented. The sensor device 403 represents the recognized driver position of the central controller 60 available, which contains the information about the driver position in the control of the damper device 1 considered.

The consideration of the respectively assumed driver position in the control of the damping properties offers considerable advantages for the suspension control 300 , Each driver position has its own characteristic load distribution on the bike 200 represents a change in the driver's position also affects the damping properties. Thus, the recognition of different driver positions, the associated weight shift in the adjustment of the damping can be considered.

In the 2a are different driver positions 800 - 803 and space conditions 804 - 806 sketched. This is how the driver's position shows 800 a normal sitting position. The normal sitting position refers here to a sports bike or mountain bike, so that compared to the attitude on a touring bike results in a correspondingly extended seating position. The bike 200 occupies a horizontal spatial position here. The detection of such a driver position and spatial position preferably leads to a damper setting, in which the damping device 1 both at the rear wheel 112 as well as on the front wheel 111 is set accordingly soft. How soft the damping is finally adjusted depends on the one hand on the default settings and on the other hand determined by the weight of the driver and of course by the passing terrain.

At the driver position shown here 800 and space 804 takes the control device 60 preferably no different adjustment of the damping at the front and rear wheel before, at least as long as an adjustment is only conditional on the driver's position and spatial position. In the case of a shock z. B. on the front wheel then a different control of front and rear suspension is provided.

The driver position shown below 801 is characterized by a standing and bent forward posture. This is a horizontal spatial position 804 in front. In the situation shown here, the controller takes 60 preferably an adaptation of the damping device 1 on the rear wheel towards soft and the damping device on the front wheel in the direction of tight.

The driver's position 802 shows a centered sitting posture of the driver. The space situation 805 is directed by the upward drive. In such a combination of driver position 802 and space 805 The damping is adjusted rather taut on both the rear wheel and the front wheel. Optionally, the suspension fork is lowered.

A very far forward bent over the handlebars, sitting driver's position 803 is shown in the bottom sketch. The space situation is characterized by a steep upward drive, so the bike 200 is strongly inclined upwards. The driver often sits very far back on the saddle. The driver position shown here can therefore z. B. be reliably detected by means of strain gauges in the handlebar and saddle area. This preferably results in a setting in which the control device 60 The damping on the rear wheel tends to be taut and the damping on the front wheel is rather soft to very soft. Such a combination allows a particularly efficient uphill, because by the damping setting on the front wheel rearing of the bike at 100 can be avoided even with steep slopes.

About the input device 150 or another suitable input device which interfaces with the landing gear control 300 Preferably, the driver may also enter at least one driver position manually. In this case, the damper device 1 preferably set according to the predetermined driver position. This has the advantage that the driver is also independent of a position detection by the sensor device 403 can achieve a driver position-dependent adjustment of the damper device.

The 2 B shows further sketchy driver positions 809 . 810 and space conditions 807 . 808 , In the upper sketch shows the driver position 809 a centered sitting posture of the driver. The driver could also be centered. The space situation 807 is directed downward by lowering. In such a combination of driver position 809 and space 807 the damping on both the rear and the front wheel is rather soft, so that a good grip is achieved. This makes fast downhill runs particularly safe and comfortable. If the driver takes on a saddle when going downhill, the damping can be changed, for. For example, the front wheel associated damping can be adjusted in the direction taut.

In the lower sketch is a slightly standing, leaned back driver position 810 shown how they z. B. is taken on a steep downhill. The driver can also sit leaned backwards. The space situation 808 is directed downwards by the steep descent. In such a combination of driver position 810 and space 808 the damping at the rear wheel is softer and at the front wheel rather taut, so that a too deep immersion of the suspension fork is prevented and at the same time a good grip on the rear wheel is ensured.

Data recorded during operation may be stored locally in a memory device 45 the control device 60 get saved. The data (recognized driver positions and / or raw data) together with time data about the Recording time and / or with GPS and / or route data stored either locally and / or directly in a memory 45 on the Internet 53 get saved. This allows for later analysis and comparison with teammates or friends or with previous trips.

3a shows in a highly schematic view of a fork 114 for the front wheel 111 Application finds and 3b shows the rear wheel damper 115 , which will be described together below.

The suspension fork 114 has a shock absorber 100 on. The shock absorber 100 includes a damper device 1 in one leg of the suspension fork and a spring device in the other leg of the suspension fork. In other embodiments, the damper device 1 and the spring device 26 also be arranged in one leg together.

The shock absorber 100 becomes with the first end as a component 101 and the second end as a component 102 on different parts of the support device 120 or of the frame 113 attached to spring and damp relative movements.

The damper device 1 includes a first damper chamber 3 and a second damper chamber 4 in a common damper housing 2 , The two damper chamber 3 and 4 are separated from each other by the damper piston or damping piston 5 separated, in or on which a magnetorheological damping valve 8th a damping channel through which the magnetorheological damping fluid 9 (MRF) is flowing. While the damper housing 2 at the upper part of the suspension fork 114 and thus the frame 113 is attached, is the damper piston 5 over the piston rod 6 connected to the bottom dropout.

In the other strut of the suspension fork here is the spring device 26 arranged here as a fluid spring 261 trained spring unit 260 includes. The spring device has a housing in which the with the piston rod 75 connected suspension pistons 37 a positive chamber 270 from a negative chamber 280 separates. The positive chamber 270 forms a positive spring and the negative chamber 280 forms a negative spring whose spring force is usually lower in the rest position, but in which the spring force of the positive spring is opposite. As a result, a good response is achieved because even with small bumps, the fluid spring 261 responding. The fluid spring 261 is filled with a fluid and here with gas and preferably air.

The positive spring here comprises two sub-chambers 271 and 272 passing through a control valve 273 can be separated from each other as needed or connected to each other.

The negative spring here comprises two sub-chambers 281 and 282 passing through a control valve 283 can be separated from each other as needed or connected to each other.

The sub-chamber 272 the positive chamber 270 and the sub-chamber 282 the negative chamber 280 can via the control valve 263 be connected to each other. This will do it with the control valves 263 . 273 and 283 possible to make a pressure equalization between the positive chamber and the negative chamber at any spring position, whereby the respective characteristic of the fluid spring 261 will be changed. The control valves 263 . 273 and 283 serve as actuators, which by the control device 60 controlled actuated. As a result, the rest position can be adjusted freely and also a lowering of a fork can be achieved for example when driving uphill. In a rear shock absorber, an optional additional volume can be switched off in a sub-chamber and thus the suspension at the rear wheel for a hill climb are set harder. It is possible that only one of the control valves 263 . 273 and 283 is provided. For example, only the control valve 273 (or 283 ), so that by opening or closing the control valve 273 (respectively. 283 ) the volume of the positive chamber 270 (Negative chamber 280 ) and thus the spring characteristic of the spring unit 260 is changed.

It is also possible that the suspension fork 114 only one control valve 293 in the suspension piston 37 which has a cable or a control line 294 with the control device 60 connected is. By opening the control valve 293 can be a guest exchange at any axial position of the suspension piston 37 be enabled. A pressure equalization at a suitable location changes the rest position and leads z. B. to a lowering or to a transfer to the normal position when the suspension fork was lowered.

By suitable control of the control valves and the pressure level in the positive and / or negative chamber can be influenced.

3b shows in a highly schematic view a cross section of a shock absorber 100 for example, in the rear wheel damper 115 Application finds.

The shock absorber 100 includes a damper device 1 , The shock absorber 100 becomes with the first end as a component 101 and the second end as a component 102 on different parts the carrying device 120 or of the frame 113 attached to dampen relative movements.

In the damper housing 2 is a damping piston unit 40 provided that a damping piston 5 with a damping valve 8th and an associated piston rod 6 includes. In the damping piston 5 is the magnetorheological damping valve 8th provided, which here is a field generating device 11 and in particular an electric coil to generate a corresponding field strength. For power supply and / or data transmission is a cable 38 , The magnetic field lines run in the central region of the core 41 approximately perpendicular to the longitudinal extent of the piston rod 6 and thus pass approximately perpendicular to the damping channels. This causes an effective influence on the magnetorheological fluid located in the damping channels, so that the flow through the damping valve 8th can be effectively damped. The shock absorber 100 includes a first damper chamber 3 and a second damper chamber 4 that by the piston 5 trained damping valve 8th are separated from each other. In other embodiments, an external damper valve is also included 8th possible, which outside the damper housing 2 arranged and connected via corresponding leads.

To the end 102 hin close to the first damper chamber 4 the balance piston 72 and then the compensation room 71 at. The compensation room 71 is preferably filled with a gas and serves to compensate for the piston rod volume, which during compression in the entire damper housing 2 entry.

Not just in the damping valve 8th but here in the two damping chambers 3 and 4 Overall, here is a magnetorheological fluid 9 as a field-sensitive medium.

The flow channel 7 between the first damper chamber 3 and the second damper chamber 4 extends from the second damper chamber 4 first through the fan-like damping channels, at the other end into the collecting space 13 or in the collection rooms 13 lead. There, after exiting the damping channels, the magnetorheological fluid collects before passing through the flow orifices 14 . 15 in the first damping chamber 3 transgresses. During compression, ie in the compression stage, all flow openings are here 14 . 15 flows through. This means that the main part of the flow here through the flow openings 15 passes through and the one-way valves 17 at the flow openings 15 automatically open so that the magnetorheological fluid from the second damper chamber 4 in the first damper chamber 3 can transgress.

In the illustrated sprung state, the first damper chamber 3 completely radially from the second spring chamber 28 the spring device 26 surround. This allows a particularly compact design.

The shock absorber 100 includes a balancing device 290 , which provides pressure equalization between the positive chamber 270 and the negative chamber 280 allows. The position of the pressure compensation is adjustable. For this purpose, the compensation device 290 z. B. a telescopic balance ram 291 have, more or less from the suspension piston 37 is extendable. As a result, the extendable balance ram reaches 291 earlier (or later) a stop at the end of the negative chamber 280 , The equalizer 290 Can have an electrical cable 294 with the control device 60 be connected. When the balance ram 291 It opens a fluid opening on it, so that a gas balance and thus a pressure equalization between the positive chamber 270 and the negative chamber 280 he follows.

When rebounding the compensation device closes 290 again automatically. Depending on the position of the compensation different pressure conditions on the fluid spring 261 adjusted, which influence the chassis accordingly. It is also possible that at the end of the negative chamber 280 an adjustable or movable stop for a fixed balance ram 291 is provided to achieve a variation of the spring characteristic. Alternatively or additionally, a length-adjustable stop 297 be provided against which the balance ram 291 at an adjustable and changeable position 292 respectively. 296 strikes. When the balance ram 291 stops, the balance ram opens 291 the control valve 293 or forms a flow opening, through which a pressure equalization between positive and negative chamber can take place. 3b shows a position 292 with extended balance ram 291 , The balance ram 291 can also be retracted, leaving a different position 296 results in the compensation device 290 opens.

Furthermore, an electrically controllable and z. B. via the electrical cable 294 energized equalizing valve 293 be provided to at appropriate positions a partial or complete pressure equalization between the positive chamber 270 and the negative chamber 280 perform.

The balance ram 291 is preferably acted upon by a spring.

Furthermore, the positive chamber 270 from several subchambers 271 . 272 consist. To the basic chamber as a sub-chamber 271 can if required or on request, the sub-chamber 272 be switched to change the spring hardness and in particular to reduce. Conversely, the sub-chamber can also 272 switched off and from the sub-chamber 271 be separated when the spring hardness is changed and in particular to be increased.

Similarly, the negative chamber 280 from several subchambers 281 . 282 consist. To the first compartment 281 can if required or on request, the second compartment 282 be switched on. Accordingly, the sub-chamber 282 switched off and from the sub-chamber 281 be separated. In a further embodiment, the positive chamber comprises 270 subchambers 271 and 272 and the negative chamber 280 subchambers 281 and 282 , The equalizer 290 includes control valves in this embodiment 273 . 283 and 263 and a connection line 265 which are the sub-chambers 272 and 282 if necessary, connects with each other. Be the three control valves 273 . 283 and 263 opened, so finds a pressure equalization between the positive chamber 270 and the negative chamber 280 instead of. The position 292 the pressure compensation is arbitrary and independent of a balance ram 291 , Therefore, in such a design, neither a balance ram must 291 , another control valve 293 in the piston 37 , another adjustable stop 297 be provided.

The connection and disconnection of the sub-chambers can in all cases also be position-dependent when rebounding or rebounding.

The suspension piston 37 is at the end of the damper housing 2 intended. Arranged on it is a holder 73 who has a magnet 74 holds. The magnet 74 is part of a sensor 47 , The sensor 47 includes a magnetic potentiometer which detects a signal indicative of the position of the magnet 74 and thus the suspension piston 37 is representative. Such a potentiometer 47 allows not only the determination of a relative location, but also allows the absolute determination of the on or rebound of the shock absorber 100 , It is also possible to use an ultrasonic sensor to detect a distance.
