Description

[0001] A parking brake for a single-track vehicle is specified. This parking brake could, for example, be the parking brake of a motorcycle or a scooter.

[0002] Parking brakes on single-track vehicles usually feature conventional brake calipers operated by a cable. This solution is relatively expensive.

[0003] Publication JP 2002-284 079 A shows a parking brake for a motor scooter. A disadvantage of this parking brake is that the toothed mechanism necessitates expensive components. Furthermore, when the parking brake is applied, the teeth can jam, preventing the brake from engaging. Consequently, the vehicle must be moved until the brake engages.

[0004] Documents DE 10 2004 023 331 A1, WO 2009 / 036 787 A1 and DE 11 2010 001 397 T5 show a switchable freewheel for further developing an electromechanical vehicle brake into a parking brake, a locking device and an anti-theft device for a vehicle.

[0005] It is a problem to be solved for at least some embodiments to specify an alternative parking brake for a single-track vehicle that can be implemented cost-effectively.

[0006] This problem is solved by an object according to the independent patent claim. Advantageous embodiments and further developments of the object are further described in the dependent patent claims, the following description, and the drawings.

[0007] The parking brake for a single-track vehicle described here comprises a clamping roller and a clamping roller carrier. The clamping roller carrier is movable at least between a first position, in which the parking brake is not activated, and a second position, in which the parking brake is activated. Furthermore, the clamping roller carrier is designed to bring the clamping roller, or a circumferential surface of the clamping roller, into contact with a parking brake surface in the second position and / or to hold it in place. The parking brake surface is preferably the circumferential surface of a component that rotates during operation of the single-track vehicle. This component can be, for example, a thrust ring on the front or rear wheel of the single-track vehicle. It is also possible that the component is part of the rear axle drive of the single-track vehicle, or part of the transmission output shaft or the output of the manual transmission of the single-track vehicle. The clamping roller carrier can be, for example,be designed as a clamping shoe.

[0008] According to another embodiment, the parking brake has a positioning device by which the clamping roller carrier can be moved from the first position to the second position. The positioning device can, for example, include a brake actuator. The brake actuator can, for example, be designed to apply an actuating force to the clamping roller carrier.

[0009] According to a further embodiment, the clamping roller carrier has two ramp-shaped sections arranged relative to each other to form a recess. Preferably, the clamping roller is arranged in the recess formed by the ramp-shaped sections. In the second position, the ramp-shaped sections result in self-locking of the clamping roller and / or self-enhancing of the braking effect. Preferably, a radial frictional connection is generated between the clamping roller and the component in the second position.

[0010] Furthermore, the clamping roller carrier is designed to pivot. In particular, the clamping roller carrier can be pivoted from the first position to the second position via a pivoting mechanism, which may include a rotary bearing or swivel joint.

[0011] Furthermore, the clamping roller or the circumferential surface of the clamping roller and / or the locking brake surface of the component have a coating and / or knurling and / or toothing to increase friction.

[0012] According to another embodiment, the parking brake has a clamping roller cage for fixing the clamping roller to the clamping roller carrier. The clamping roller cage prevents the clamping roller from lifting off and / or being lost, as well as from unintentionally contacting the clamping roller with the parking brake surface of the component. Preferably, the clamping roller is movably mounted within the clamping roller cage. For example, the clamping roller cage can have a recess, which may be formed along the ramp-shaped sections, and the clamping roller can have an axle that is guided in the recess of the clamping roller cage.

[0013] The parking brake described here is advantageously inexpensive to manufacture and lightweight. Furthermore, the parking brake is advantageously characterized by its ease of use.

[0014] Further advantages and advantageous embodiments of the parking brake for a single-track vehicle described here will result from the following in conjunction with the Fig. 1, Fig. 2 to Fig. 3 described embodiments.

[0015] They show: Fig. 1 and Fig. 2 a schematic representation of a parking brake for a single-track vehicle according to an exemplary embodiment, and Fig. 3 a schematic representation of a parking brake and a sectional view of the parking brake along section AA according to a further embodiment.

[0016] In the exemplary embodiments and figures, identical or similarly functioning components may be designated with the same reference numerals. The depicted elements and their relative sizes are not necessarily to scale.

[0017] The Fig. 1 and Fig. Figure 2 shows a parking brake 1 of a single-track vehicle as described herein, according to a first embodiment. The Fig. 1. The parking brake 1 in a first position or in a disengaged position, as it would be, for example, during operation or travel of the single-track vehicle. Fig. Figure 2 shows the parking brake in an activated position, or in the second position or parking position.

[0018] The parking brake 1 has a clamping roller 2 and a clamping roller carrier 3, which is designed as a clamping shoe pivotable about a bearing 11. The clamping roller carrier 3 is located between the first position, in which the parking brake 1 is not activated ( Fig. 1), and the second position in which the parking brake 1 is activated ( Fig. 2), movable or swiveling.

[0019] The clamping roller carrier 3 is designed to bring the clamping roller 2 into contact with a parking brake surface 4 of component 5 in the second position, or to keep it in contact with that component. Component 5 is a component that rotates during operation or travel of the single-track vehicle. The parking brake surface 4 is the circumferential surface of component 5.

[0020] Component 5 could, for example, be a thrust ring on the rear or front wheel of the single-track vehicle. Furthermore, component 5 could, for example, be a component of the rear axle drive or a component of the gearbox of the single-track vehicle.

[0021] The clamping roller carrier 3 has two ramp-shaped sections 6 and 7 arranged relative to each other to form a recess in which the clamping roller 2 is positioned. The ramp-shaped sections 6 and 7 are designed such that a self-locking mechanism is created for the clamping roller 2 in the second position. The arrangement of the ramp-shaped sections 6 and 7 restricts the movement of the clamping roller. Furthermore, in the second position, a radial frictional connection is created between the clamping roller 2 and the component 5, preventing the single-track vehicle from moving in this position.

[0022] As an alternative to the embodiment shown, the circumferential surface of the clamping roller 2 and / or the locking brake surface 4 of the component 5 can have a coating and / or knurling and / or toothing to increase friction.

[0023] The Fig. Figure 3 shows a parking brake 1 according to a further embodiment. In contrast to the one associated with the Fig. 1 and Fig. In the embodiment described in Figure 2, the parking brake 1 has a clamping roller cage 8 for fixing the clamping roller 2 to the clamping roller carrier 3. The clamping roller cage 8 is directly connected to the clamping roller carrier 3. The clamping roller 2 is movably mounted within the clamping roller cage 8.

[0024] The clamping roller cage 8 has a recess 9 extending along the ramp-shaped sections 6, 7, in which an axle 10 of the clamping roller 2 is guided. The clamping roller cage 8 advantageously prevents the clamping roller 2 from being lost or from unintentionally coming into contact with the component 5.

[0025] The features described in the illustrated embodiments can also be combined according to further embodiments. Alternatively or additionally, the embodiments shown in the figures can have further features according to the embodiments described in the general description.
