Definitions
- the invention relates to a trailer for a bicycle, pointing to ⁇ a drawbar for coupling to the bicycle and acting on a wheel or the wheels of the trailer braking device.
- Such a bicycle trailer is described for example in DE 10 2010 051 838 AI.
- an acting on the brake of the trailer electronic logic circuit is provided, which is set up so that the trailer during coasting and braking of the bicycle does not exert a noticeable effect on the handling of the bicycle.
- the electronic logic circuit signals of a pedal pressure sensor, a brake force sensor, a force sensor in the trailer hitch and a revolution sensor are supplied. Except for the revolution sensor, which is arranged in the area of one of the wheels of the trailer, the sensors are arranged on the bicycle.
- a disadvantage of the proposed trailer is that this can not be operated universally with conventional bicycles in the proposed manner, since the trailer requires wheel-side sensed sensor data.
- the trailer is thus usable in the proposed mode of operation only with a bicycle equipped with corresponding sensors for detecting the data required for the logic circuit.
- the object of the invention is in particular to provide a bicycle trailer that exerts no noticeable effect on the behavior of the bicycle when braking the bicycle and that can be used universally with conventional bicycles.
- the bicycle trailer according to the invention has, in accordance with the prior art, a drawbar for coupling on
- the trailer further comprises a sensor device which delivers a measured variable which is a measure of an acceleration force acting on the trailer via the drawbar.
- the sensor device can be designed, for example, as a force sensor which measures a force acting on the drawbar.
- the sensor device can also be designed as a travel measuring unit, which detects a deflection caused by the acting acceleration force.
- the sensor device can be integrated in the coupling, in the drawbar or in the attachment between drawbar and trailer.
- the trailer further comprises a regulator acting on the brake device of the trailer, which is set up to act on the brake device depending on the measured variable determined by the sensor device such that an inertial force of the trailer generated during braking of the bicycle is compensated or at least reduced.
- the trailer thus has a control circuit, in which the measured variable detected by the sensor device serves as a controlled variable for the controller, which in turn outputs a corresponding manipulated variable to the braking device.
- the controller determines a value of the manipulated variable so that the bicycle trailer is decelerated when braking the bicycle so that an inertial force of the trailer is reduced or compensated. A compensation of the inertial force causes the pendant ⁇ nger during driving behavior no appreciable effect on the driving of the bicycle exercise.
- a particular advantage of the invention is thus that the driving characteristics of a coupled with the trailer bike when braking by means of converted in the trailer Brake control less or preferably not significantly changed for the driver.
- a braking distance is shortened, which increases road safety.
- the trailer further comprises a decoupling device, which is designed for the partial mechanical decoupling of a movement of the bicycle trailer to the bicycle in the longitudinal direction of the bicycle trailer. Movement in the longitudinal direction is understood to mean a movement in or counter to the direction of travel.
- the decoupling device thus allows a limited relative movement of the bicycle trailer to the bicycle in or against the direction of travel when the trailer is coupled to the bicycle, in particular such that the bicycle trailer reacts delayed to a pulling movement or braking movement of the bicycle.
- the partial mechanical decoupling offers the advantage of smoothing jump-like acceleration forces and a delayed reaction of the trailer body, so that the inertial force of the trailer body is not immediately perceived by the cyclist.
- the delayed reaction of the trailer body can be utilized by the control circuit for determining the value of the manipulated variable, in order to apply, in accordance with the determined value of the manipulated variable, a suitable reaction force for compensating or reducing the inertial force generated in the trailer.
- the decoupling device In conjunction with the partial mechanical decoupling, it is also possible to achieve a particularly jolt-free compensation of the forces of inertia, which is less perceptible to the cyclist, and thus improved driving dynamics.
- a further advantage is that the provision of the decoupling device enables a particularly accurate and structurally simple determination of the aforementioned measured variable, which is a measure of an acceleration force acting on the trailer via the drawbar, which will be explained in more detail below.
- the trailer further comprises an electric drive for driving the trailer, wherein the controller is further configured to accelerate the trailer by means of the electric drive so that one in train operation, depending on the measured variable determined by the sensor device inertial force of the trailer generated by the bicycle is compensated or at least reduced.
- the force in the drawbar can thus preferably be regulated to a value of zero, so that the trailer is no longer perceived by the cyclist as inertial mass.
- the trailer according to the invention does not require any operating unit or sensor device attached to the bicycle and thus can be used flexibly with conventional bicycles which only require a conventional coupling for fastening the drawbar.
- the decoupling device is advantageously provided with a spring-damping function, ie the decoupling device has resilient and damping properties.
- the resilient function allows a provision of the decoupling device in a central position, while the damping function limits the vibrations occurring.
- the sensor device may be provided on the decoupling device.
- the sensor device can be set up to derive a measure of the acceleration force acting on the trailer via the drawbar on the basis of the limited relative movement between the bicycle and the trailer made possible by the decoupling device. Based on the limited relative movement between the bicycle and the trailer, the acceleration forces acting on the trailer can be accurately determined in the direction of travel.
- the sensor device may be configured to determine a deflection of a movable element of the decoupling device, wherein the deflection of the movable element is a measure of an acceleration force acting on the trailer via the drawbar.
- the sensor device may comprise a force sensor with which the force acting on the decoupling device acceleration force can be measured directly.
- the invention is not limited to a particular type with regard to the measuring principle or structural design of the sensor device used.
- the sensor device may comprise at least one strain gage (DMS), which is a cost-effective and easy-to-install way, since a strain gauge can be glued directly to the element, which is subject to stretching due to the force of the cyclist.
- the sensor device tion may further comprise a Hall sensor and / or a piezo bending beam sensor.
- stop means which limit a relative movement of the bicycle trailer to the bicycle to a predetermined maximum value, can also be provided on the decoupling device.
- large acceleration forces do not have to be completely absorbed by the spring damping function of the decoupling device, but can be absorbed by the stop means.
- the movable elements of the decoupling device for smaller forces and the sensor device can be designed for a smaller measuring range and thereby work more precisely.
- the decoupling device may be provided in the connection between the bicycle and the trailer, for example at the coupling between the bicycle and the trailer or along the drawbar.
- the decoupling device comprises two bending elements, each at one end on the trailer body and at the opposite end to the drawbar are attached.
- the bending elements extend here in the non-deflected state substantially transverse to the longitudinal direction of the trailer and are bendable in the longitudinal direction of the trailer.
- the two bending elements are preferably designed plate-shaped and can be made for example of a carbon fiber composite material.
- the size, the thickness and the material of the bending elements, the resilient and damping properties of the decoupling device formed by the bending elements can be adjusted.
- a particular advantage of this embodiment lies in the structurally simple structure, since no additional storage or storage elements are required.
- the sensor device can have at least one piezo bending beam sensor, which is arranged parallel to one of the bending elements, such that the piezoelectric
- Bending beam sensor performs a deflection corresponding to the bending element under the action of a force and the charge displacement of the piezoelectric element is thus proportional to the deflection of the bending elements.
- the sensor device may have a Hall sensor, which is arranged so that a magnetic flux through the sensor is proportional to the deflection of the bending elements.
- the sensor on the trailer and a corresponding magnet adjacent to it can be mounted on the drawbar.
- the sensor device has the possibility of that the sensor device comprises one or more strain gauges (DMS), which are applied to one or both bending elements, for. B. are glued.
- DMS strain gauges
- the elongation of the bending elements can be measured. From the strain can be deduced on the acceleration force.

- a bending body which at one end on the trailer body and at the opposite end to the
- Tiller is attached, be provided, which extends transversely to the longitudinal direction of the trailer and is bendable in the longitudinal direction of the trailer.
- the spring stiffness and damping of the decoupling device is thus not by the two
- Swing arms but provided by the additional bending body, which in turn is subjected to shear.
- the decoupling device is not limited to the two abovementioned variants having the bending elements or the pivoting arms, which, however, are particularly advantageous for cost and production reasons.
- the decoupling device comprises at least one spring which can be deflected in the longitudinal direction.
- the translatory degree of freedom of the decoupling device in the longitudinal direction of the trailer can be realized by a guide mechanism, by means of which a carriage can slide limited by stops in the longitudinal direction.
- the guide mechanism can, for example, by a guide rail and
- Linear ball bearing be realized.
- On the carriage can be attached to form the spring-damping function of the decoupling device two springs which are deflectable in the longitudinal direction of the trailer.
- a spring is fixed with its not attached to the carriage end to the drawbar and the other spring with its not attached to the carriage end to the trailer body.
- the carriage may be formed as a Z-shaped plate, wherein at the two diagonally opposite ends in each case a spring is attached.
- the electric drive can be designed as a wheel hub motor.
- the wheel hub motor is provided only on one of the wheels of the trailer, as this is advantageous for cost reasons and due to better handling characteristics in the curve.
- a wheel hub motor can be attached to each of the two wheels of the trailer.
- the electric drive can also be designed as a conventional electric motor.
