Description

TECHNICAL AREA

The technical field relates to brake levers and means for operating the brake levers. In particular, brakes for stepless adjustment of hand or foot brake levers are particularly affected on handlebars. An application for this are, for. B. Hand brake lever on the handlebars of two-wheelers or any other type of vehicles, especially aircraft. In particular, the invention relates to locking devices according to the preamble of claim 1 and the use of self-locking components therefor.

BACKGROUND

Brake levers with brakes are in many cases designed so that the angle of rotation from the brake lever to the brake bearing block can be determined by pawls or detents. Such devices are z. In DE 10 2007 040 293 A1 or DE19522259A1 described, in particular also for use on handlebars.

With conventional pawls, a design-specific way must be covered in order to lock the pawl can. In addition, it is necessary to set the brake system so that there is enough braking effect when the handbrake is locked. In particular, due to Temperaturschwankungs- and wear length change of the actuating system must be readjusted if necessary quite often the actuation path.

Lock with detents are effective over a larger tolerance. With the pawls they have in common that they have to lock the brake lever only a certain angle of rotation must be covered in order to engage the pawl or detent. Here, therefore, a certain force is required, which consequently also claims the system (trains and bearings).

In both systems, it is possible to adjust the locking device so that it automatically engages or disengages when the brake lever is actuated. Depending on the setting, this may result in unintentional latching or unlatching. In addition, it may happen that the barrier construction is not fully engaged and in particular due to vibration jumps out again. Here is a potential risk, or a source of danger, especially when used in larger passenger vehicles. Trusting to leave you alone do not want vehicles with such braking devices so much.

A stepless locking device for a motor vehicle hand brake is z. B. already in DE19800974A1 been described. However, it operates on a different operating principle than the invention presented here, namely by means of mechanical clamping elements, which are formed of individual fingers with open-ended heads, wherein a brake cable is actuated via a pull rod, which is actuated by means of a push button, which upon actuation a linearly mounted on the pull rod housing. A structure that might require a very fine tuning.

Other arrangements of brake valves z. In JP H09-142 359 A , in CH 212 319 A or in US 3,546,960 A described.

The invention has for its object to provide a locking device by means of which a (hand) brake lever in a simpler, more flexible and / or safer way can be determined, in particular continuously. It is desirable that the system can be integrated in a (hand) brake lever fitting or can be attached to existing brake valves as an independent assembly.

SUMMARY

This object is achieved by the subject matter of claim 1 or by the use of a locking device or components thereof described below.

There is provided a locking device for stepless adjustment of a brake lever, in particular on hand or Fußbremshebelarmaturen, especially on handlebars, in which a pressure bridge in the manner of a cantilevered lever and a cam, in particular spiral eccentric are geometrically mutually corresponding respectively rotatably mounted on the brake lever in that the angle of rotation of the brake lever, relative to a brake lever bearing block on which the brake lever is mounted, is thus infinitely ascertainable, in particular in the closing direction. Such a locking device allows a brake can be sensitively detected regardless of Einstellschwankungen the actuating travel continuously to the desired braking effect. Likewise, the brake can be continuously steered or released directly. The pressure bridge and the cam can each be mounted on a rocker rotatably mounted on the brake lever.

In the following description, the principle of the invention is explained in more detail and described in more detail by way of example, in particular, also as an attachment design to a handbrake lever. For this purpose, further developments and exemplary embodiments are described below.

According to one embodiment, the angle of rotation can be determined by support to impact or by frictional support of the pressure bridge to a housing or brake lever bearing block, in particular without positive locking. This allows various intermediate positions and can ensure effective support with advantageous levers. In addition, the locking device can be easily adapted to specific arrangements or ergonomic requirements.

According to one embodiment, the locking device has at least one Wälzpaarung at least formed by the pressure bridge and the cam. Pressure bridge and cam can form abutting abutment. In this case, a blocking gear function can be provided by means of the abutment or Wälzpaarung. Pressure bridge and cam may have geometrically corresponding to each other trained rolling contours. The formation of a Wälzgetriebes by means of rolling elements not least provides the advantage of a large variability. The individual rolling elements can be arranged, dimensioned or shaped for blocking or securing themselves in desired positions. The individual rolling elements can be displaced together with the brake lever relative to the housing.

According to one embodiment, the locking device has at least one Wälzpaarung for predetermining the angle of rotation or a plurality of rotational angular positions of the brake lever, wherein axes of rotation of rolling elements of Wälzpaarung are rotatably mounted about the axis of rotation of the brake lever, so flying, not stationary, but in particular rotatable about a Momentanpol , The axes of rotation of Wälzpaarung can be performed on circular orbits about the axis of rotation of the brake lever, in the manner of a planetary motion, as the sun or fixed star anyway the pivot or the axis of rotation of the brake lever is definable. Depending on the embodiment, the system may only have planets or moons. According to a variant, the rotary joint or the axis of rotation of the pressure bridge and the cam disk can be defined as a moon, which moon rotates about the rotary joint or the axis of rotation of one rocker (planet). According to another variant, the rotary joint or the axis of rotation of the pressure bridge and the cam disc can be defined as a planet, which planet rotates about the sun (axis of the brake lever). Such a system does not necessarily have a moon as well. Pressure bridge and cam can be mounted either on a planet or moon orbit around the axis of rotation of the brake lever.

The relative position of the axes of rotation of the Wälzpaarung relative to each other can be predefined. This arrangement provides ergonomic advantages in addition to a high variability in the setting of different Wälzkurven for self-locking or frictional engagement. On the one hand results on the shape of the rolling elements, on the other hand on their relative arrangement to each other and the axis of rotation of the brake lever, a very wide range of possible variations, especially with regard to a wide range of leverage or Zugseilkräften, depending on the application.

According to one embodiment, the locking device on at least three or four axes of rotation, of which two or three are movably mounted and mounted relative to each other in predefined relative position, and on which at least the brake lever, the pressure bridge and the cam are rotatably mounted, and optionally also a pressure intermediate piece is rotatably mounted between the pressure bridge and a housing or brake lever bearing block for the locking device. This can also ensure the aforementioned variability.

According to one embodiment, the pressure bridge and the cam and optionally also a pressure intermediate piece are mounted together with the brake lever rotatable about the axis of rotation of the brake lever. This allows various relative positions for specifying rotational angle positions of the brake lever.

The locking device may have at least two or at least three rolling elements mounted on each other rolling, in particular the pressure bridge and the cam and optionally also a pressure intermediate piece, one of which manually operable and one on the housing or. Brake lever bearing block is supportable. This provides a simple, robust construction with high variability.

According to one exemplary embodiment, the pressure bridge has a convex contour adapted for supporting in a plurality of relative positions on / on the housing or brake lever bearing block, or wherein the convex contour forms a rolling pair together with the housing or brake lever bearing block. This provides benefits previously described.

According to one embodiment, the pressure bridge has at least one pressure side with a convex contour, in particular two pressure sides each with a convex contour or a pressure side with a concave contour and a pressure side with a convex contour, wherein the pressure sides can taper on one side. The pressure bridge is mounted between the pressure sides as a one-sided lever. The tip can have a small radius. By means of the spiral eccentric disc is a compressive force on the Pressure bridge transferable, in particular to the pressure bridge at a shoulder or edge of a bearing block on which the brake lever is mounted, to wedge or press against it, in particular the front side.

According to one exemplary embodiment, a beginning and / or end of a spiral curve contour of the spiral eccentric disk formed geometrically corresponding to the pressure bridge merges into an actuating lug of the spiral eccentric disk, wherein the pitch ratio of the spiral curve contour is designed for self-locking. As a result, the positioning lug remains in a rotational angle position that has been set once, without any additional form-locking locking mechanism having to be actuated. The spiral eccentric disc is set up, self-locking, z. B. by frictional forces, ie frictional connection, or even positive engagement, to be positioned at the pressure bridge in freely selectable rotational angle positions.

According to one embodiment, the rocker is attached as a two-sided lever on the brake lever or on a brake lever bearing block on which the brake lever is mounted or integrated therein, that the rocker is pressed on one side with a spring against a stop formed on the brake lever. The spring is preferably arranged on a side lying opposite the pressure bridge-seen relative to the axis of rotation of the rocker-and designed as a compression spring.

According to one embodiment, the cam, in particular spiral eccentric and the pressure bridge are rotatably mounted on the brake lever, in particular on the rocker that they form at each convex contours at least one Wälzpaarung, or such that upon rotation of the cam and / or pressure bridge / a convex Contact contour of the pressure bridge and the spiral eccentric curve over a predefined rotation angle range or can be rolled onto one another. This allows stepless adjustment even with very good ergonomic properties and direct, rotational position-specific (pressure) power transmission.

According to one exemplary embodiment, the pitch of a spiral eccentric contour changes in the opposite direction to a rotational stroke or a direction of rotation of the pressure bridge. An example: If the cam rotates clockwise, the pitch increases and causes the pressure bridge to roll on the cam and rotate clockwise. In the circumferential direction on the cam, the slope increases in the counterclockwise direction. This allows a comparatively sensitive locking of the brake lever, in particular in an already quite tightened position of the brake lever. By means of the slope, the translation and thus also the pressure exerted on the pressure bridge pressure force can be adjusted.

According to one exemplary embodiment, a part of the concave contour or one of the convex contours of the pressure bridge, in particular a pressure bridge tip, can be positioned for spacing at a stop or a pressure point or a pressure contour of a brake lever bearing block on which the brake lever is mounted / storable or on the brake lever bearing block engageable. This allows effective engagement in different rotational positions.

According to one embodiment, the pressure bridge with a / the tip behind a / the stop of the brake lever on a brake lever formed on the rocker bearing base can be supported, in particular in an unactuated arrangement. This arrangement corresponds to in 1 shown position "off" the locking device. The convex reverse side or contour of the pressure bridge can form a positive fit with the rest position bulge at the beginning of the slope of the spiral eccentric curve. This curve area is not designed for self-locking.

According to one embodiment, a grinding hump is arranged or formed on the cam, in particular spiral eccentric disk. By means of the Schleifbuckels the positioning of the disc can be facilitated. The operation can also be more intuitive, especially without having to pay attention to an exact position of the disc or flag.

According to one embodiment, a detent bore or bead or a grinding hump is formed on the brake lever or on the pressure bridge, and / or the locking device has a leg spring and / or a spring-loaded detent ball as rest position detent. This facilitates the positioning of the brake lever, in particular an automatic reset when the brake lever is not tightened.

As already mentioned, the pressure bridge and the cam disk can also be mounted rotatably on the brake lever on a rotatably mounted rocker. This results in more relative positions. The pressure bridge and the cam may be (unchanged) mounted around the axis of rotation of the brake lever, but in addition also about an axis of rotation of the rocker. The pressure bridge and the cam can form a Wälzpaarung, which are mounted together about two axes of rotation, of which a rotation axis is rotatably mounted about the other axis of rotation. In this way, a momentary pole for the pressure bridge and the cam can be realized, which deviates from the axis of rotation of the brake lever, at least temporarily emigrated. This results in new, more relative positions and can be used to adjust the angle of rotation of the brake lever facilitate specific arrangements. The pressure bridge and the cam, or the Wälzpaarung, may be resiliently biased pivotally mounted about an axis of rotation which is mounted on a circular path displaceable about the axis of rotation of the brake lever.

In particular, the pressure bridge and the cam can be mounted on a rotatably mounted rocker, which rocker is attached as a two-sided lever on the brake lever or on a housing or brake lever bearing block or integrated therein that the rocker is pressed on one side with a spring against a stop formed on the brake lever , This also provides a simple adjustment option.

According to one embodiment, an annular groove segment is formed on the rocker, in particular on an inner surface, in a circular segment about a bearing bore of the cam disk, in particular spiral eccentric disk. Optionally, a piece of the rocker can be unlatched around the bearing bore. In this case, the annular groove segment can be arranged or dimensioned for interaction with the grinding hump or formed geometrically.

The operation of the locking device will be explained in more detail below.

The stepless adjustment takes place, for example, by pulling the (hand) brake lever and tracking an / the flag, whereby a / the cam is rotated. The cam may have the shape of a spiral eccentric disc whose contour slides on a lever mounted on one side and presses. Such a lever is referred to below as a pressure bridge. The pressure bridge and the spiral eccentric can be rotatably mounted in the radial direction on a rocker or housing rocker. The rocker may be attached to a lever assembly or integrated therein, in particular rotatable about an axis mounted in the lever assembly.

Stepless adjustment is to be understood as a continuous or continuous setting independent of discrete (latching) positions.

By turning the cam, the lock bridge fails. At the opposite part of the active pair brake lever - brake lever bearing comes the pressure bridge deflection to the system and prevents pivoting back of the actuated brake lever. The lock is located on the brake lever or brake lever bearing. The slope of the spiral eccentric of the cam can be designed for self-locking friction, so that the disc does not turn back automatically under load by the brake actuation force. In this case, the pitch curve of the spiral eccentric curve can be designed so that the self-locking only after overcoming an initial route - is secured - about the length of a brake actuation game. This means that the spiral eccentricity curve slope is not self-locking in this area. Upon release of the brake lever and actuated scroll cam, the pressure bridge and the scroll cam may spring back to a secured "off" position. In order for a transition from this unsecured Spielwegstellung to the secure locking position for the operator is noticeable, a noticeable Verstellwiderstand can be generated on the usable Feststellweg, in particular by a grinder. This also prevents inadvertent self-adjustment of the spiral eccentric disc by a brake lever operation.

The grinder consists for example of a projection on the surface of the spiral eccentric disc and rubs against the wall of the bowl rocker. A reverse arrangement of this adjustment resistance system is also possible. Then z. B. the hump be replaced by a resilient pressure piece. In the transition of the spiral eccentric curve to the rest position bulge, the hump can move without friction in an annular groove segment. Optionally, a piece of the (bowl) rocker can be disengaged in the appropriate area. To release the brake, the brake lever is pulled slightly to cancel the frictional force between the cam and pressure bridge. The spiral eccentric disc is rotated against the slope, so that the applied pressure bridge can swing back to release the blocking path.

The direction of rotation of the spiral eccentric slope curve is opposite to the direction of rotation of the pressure bridge. This has the following advantages: brake lever actuating direction and brake lever locking direction are the same. The contact surface of the pressure bridge acts against the slope surface of the spiral eccentric curve. This causes an increasing torque and clamping reinforcement in the reverse direction by the recorded Bremsfeststellkräfte.

In the off position of the locking device (position of the smallest pitch of the spiral eccentric cam) and the return of the brake lever, the pressure bridge is displaced from the closing opening gap of the stops between brake lever bearing block and brake lever and slides over the edge of the base of the rocker bearing socket. The edge acts as a pressure point behind which the pressure bridge tip jumps to a safe home position.

The pressure bridge is transmitted by the counteraction of the compression spring, transmitted through the Bowl rocker, held in a stable position between spiral eccentric disc and rocker bearing base. The pressure bridge is mounted on the rocker. Form contact in the rest position bulge of the spiral eccentric disc with the convex back of the pressure bridge prevents independent rotation / adjustment of the spiral eccentric disc.

According to one embodiment, the direction of action of a pressure bridge and the cam disc oppressive force from a housing or brake lever bearing block towards the brake lever. With hand brake lever, it will be useful in many cases, by means of a Bremszugseiles exert a tensile force from the brake lever in the direction of the housing. The opposite effective direction of the housing / bearing block in the direction of the brake lever can be particularly advantageous if a foot brake lever is to be locked.

The aforementioned object is also achieved by a locking device, in particular a locking device described above, produced by forming at least one Wälzpaarung at least by a / the pressure bridge and / a cam of the locking device, which Wälzpaarung is mounted around at least three or four axes of rotation, of which two or three are movably mounted relative to a housing or brake lever bearing block and are mounted relative to each other in predefined relative position. This gives advantages previously described.

The above object is also achieved by the use of a locking device described above for providing a lever mounted on a handlebar brake lever for continuously adjusting the brake lever relative to a housing or brake lever bearing block. This gives advantages previously described.

The above object is also achieved by the use of a locking device, in particular a locking device described above, for providing a continuously adjustable brake lever, wherein the locking device comprises at least two rolling elements rolling against each other at least comprising a pressure bridge in the manner of a cantilevered lever and a cam, one of which is brought into engagement with a gap between a fixedly arranged brake lever bearing block and the brake lever pivotally mounted thereon in response to a rotational movement of the other, or of which one in response to a rotational movement of the other at predefined contact points along a pressure contour on a Housing or brake lever bearing block or is positioned relative thereto. This results already mentioned advantages.

The aforementioned object is also achieved by the use of a locking device, in particular a locking device described above, on a handlebar for providing a continuously adjustable, attached to a handlebar brake lever, wherein the locking device comprises two rolling elements rolling against each other, one of which in response to a rotational movement of the other is brought into engagement in a gap between a stationary block and the rotatably mounted thereon brake lever. The locking device may be formed of five interacting with each other and relatively movable parts, of which four parts are movably mounted, in particular in each case relative to each other. This results already mentioned advantages.

The aforementioned object is also achieved by the use of a locking device for providing a continuously adjustable brake lever, in particular a locking device described above, wherein a rocker of the locking device is rotatably mounted on the brake lever, wherein the rocker has three axes of rotation, of which a rotation axis of a pivot bearing Rocker forms and wherein about the other two axes of rotation geometrically mutually corresponding parts, in particular a pressure bridge and a cam, in particular spiral eccentric, in different rotational positions are mutually storable, wherein the two parts for locking the brake lever in a desired position of geometrically corresponding contours rolled together become. This results already mentioned advantages.

The aforementioned object is also achieved by using a locking device described above for continuously adjusting a brake lever, wherein a respective position of the brake lever by means of at least one Wälzpaarung from at least two flying rotatably mounted rolling elements at least comprising the pressure bridge and the cam is defined.

DETAILED DESCRIPTION OF THE FIGURES

With respect to reference numerals which are not explicitly explained in one of the figures, reference is made to the other figures.

In the 1 is a bearing block 4 on a handlebar 30 attached. On the bearing block 4 is a brake lever 5 stored, in a swivel joint 13d , The components described below form at least partially a stepless locking device 20 without locking positions. The brake lever 5 can be adjusted continuously. In other words, the braking force can be adjusted continuously. At the brake lever 5 is a seesaw 3 in a swivel joint 13c stored. On the seesaw 3 is a manually operated spiral eccentric disc 2 in a swivel joint 13b stored. Further, on the rocker 3 also a lever 1 , here called pressure bridge, in a swivel joint 13a stored. On the seesaw 3 Thus, two geometrically corresponding parts are rotatably mounted. The respective rotary joint can also be referred to as a bearing axis or pivot bearing. The swivel joint 13a is in geometrically predefined positional relation to the hinge 13b arranged. Thus, the rocker points 3 three hinges or pivot points or axes of rotation on which or around which in each case a relative rotational movement can take place, on the one hand the rocker itself, on the other hand pressure bridge 1 and spiral eccentric disc 2 , At least two of the swivel joints 13a . 13b . 13c form a continuously adjustable pivot bearing assembly 13 ,

The flat, drop-shaped pressure bridge 1 is longer than a distance dz between the rotation axis 13a and the bearing block 4 , This allows that in a tightened position of the lever 5 a peak 16 the pressure bridge in engagement with or for abutment against an edge or an edge or stop 14 of the bearing block 4 can come as in 2 shown. Because if the lever 5 in the direction of the handlebar 30 is pulled, increases the distance dz and there is a gap between the upper edge of the lever 5 and the adjacent edge 14 of the bearing block 4 , The gap is due to the fact that the axis of rotation 13d of the lever 5 is arranged at a distance dz1 to the upper edge.
