Definitions
- the invention relates to a device for actuating a brake for a motor vehicle according to the preamble of claim 1 and according to the preamble of claim 14, comprising a brake lever pivotally mounted on a lever holder lever, a coupling unit which couples the brake lever and a brake cable, wherein the coupling unit a pulley arranged pivotably on the brake lever, wherein a toothing is arranged on the pulley, which can be coupled with a arranged on the brake lever lever, a arranged on the sheave linkage for the brake cable, and a pulley biasing spring element.
- DE 102 12 673 A1 shows a device for actuating a brake for a motor vehicle, in which a hand brake lever is pivotably arranged on a lever holder, wherein the brake actuating lever is coupled by means of a coupling unit with a brake cable.
- the coupling unit comprises a pulley pivotally arranged on the brake lever, wherein the pulley has a linkage for the brake cable.
- the pulley has a toothing, which is in engagement with a pivotably arranged on the brake lever lever.
- the pulley is acted upon by means of a first spring element for tensioning the brake cable.
- the pawl is biased by a second spring element against the arranged on the sheave toothing.
- a disadvantage of this type of device is the fact that the coupling unit has many components, so that the assembly work for the coupling unit is high.
- the pawl by means of the spring element against the toothing prestressed, whereby a secure engagement of the pawl is provided in the arranged on the sheave toothing and thus a secure transfer of the pivotal movement of the brake lever is ensured on the brake cable.
- the pawl and the lever are coupled together by means of an extension and a recess, wherein preferably the extension is arranged on the pawl and the recess on the lever.
- the extension is arranged in the recess for this purpose.
- the lever is advantageously pivotally mounted on the brake lever, whereby a pivoting movement of the Hebeis is given and by the coupling with the pawl, this can be further securely engaged with the teeth in and disengaged.
- Levers can be transferred to the latch.
- the pawl and the lever are connected to each other by means of a hinge, so that a pivoting movement of the lever is transmitted to the pawl.
- the lever and the pawl on the same pivot axis, wherein the pawl and the lever are pivotally mounted on the brake lever, whereby the structural complexity of the coupling unit and the space for the device is further reduced.
- a bolt is advantageously arranged, wherein the lever by means of the bolt on the brake lever is releasably fixed. This ensures that the lever in a simple manner to the brake lever in the first position, the transport position, can be fixed, wherein the bolt forms the positive connection with the brake lever.
- the latch is associated with a tab for releasing the lever from the Bremsbeuschistshebel, wherein by moving, for example pulling, the tab of the bolt with the lever disposed thereon is moved such that the positive connection with the brake lever is released.
- This ensures that the Lever can be easily solved by the brake lever, so that the brake from the transport position in which the pulley is locked, in the operating position in which the pulley is rotatable for tensioning the brake cable, can be brought.
- a translation between the spring element and the locking pawl wherein the translation as a result of different Hebelarmin between the inherent by the spring element of the lever arm and given by the lever and the pawl lever arm, said this from the articulation of the spring element on the lever extends to the engagement tip of the pawl on the toothing, is given.
- the thus generated locking force for the pawl is thereby greater than the pulley acting on the spring force of the spring element, wherein the ratio of the Nachspannkraft and the locking force is approximately proportional.
- a force adjustment of the locking of the pulley for actuating the brake is given by the engagement of the pawl in the toothing, wherein by the spring element on the one hand a force for tensioning the brake cable on the sheave and on the other hand a force to lock the sheave with the brake lever by means of Gearing and the pawl is given.
- the translation given by the lever ensures that the holding force acting on the pawl by the spring element is always greater than the tensioning force acting on the pulley by the spring element, so that a secure actuation of the brake is ensured without the tensioning device being locked during the process Actuation can be triggered.
- the lock is thus insensitive to component tolerances, since these are compensated by the elastic coupling of the sheave with the pawl.
- Fig. 1 shows a preferred embodiment of a device according to the invention for actuating a brake.
- a preferred embodiment of the device 1 according to the invention is shown in which a brake actuation lift! 2 on a lever holder 3, which is indicated schematically, is pivotally mounted.
- a pulley 4 is pivotally mounted about a pivot axis S, wherein on the pulley 4 a hook-shaped linkage 5 is provided for a brake cable 6, wherein the end of the brake cable 6 is eingahkt in the hook-shaped linkage 5.
- the pulley 4 is circular over an angle of approximately 135 ° and has a circumferential groove 4a, with which the brake cable 6 is arranged over an angular range of approximately 70 °.
- the sheave 4 is flattened and has a wave-shaped course, whereby the sheave 4 can be adapted to the space provided for the device 1 space.
- the articulation 5 for the brake cable 6 is provided on the flattened portion of the sheave 4.
- a spring element 7 is arranged with a first end on a projection 4b.
- the spring element 7 is designed as a tension spring and acts on the sheave 4 with a
- a toothing 8 is arranged, which has a curved course, wherein the curvature is approximately circular, ⁇ wherein the center is given by the pivot axis S of the Seiibeibe 4.
- the toothing 8 has three projections 8a, which form two corresponding recesses 8b " on the toothing 8. On the pulley 4, two projections 4c are formed, which are arranged in the recesses 8b of the toothing 8, whereby the toothing 8 on the pulley 4 is arranged.
- the toothing 8 has a plurality of teeth 9, which are arranged uniformly along the arcuate course. At the one end of the toothing 8, a recess 10 is provided, wherein the Ausnhemung 10 has the same orientation as the teeth 9.
- a pawl 11 can be brought into engagement, wherein the pawl 11 about an axis W, the. is provided parallel to the pivot axis S of the pulley 4, is pivotally mounted on the brake lever 2.
- the pawl 11 has an engagement tip 12, which has two adapted to the teeth 9 of the teeth 8 teeth 13.
- the pawl 11 has an extension 14 which is provided at the opposite end of the pawl 12 of the pawl 11, so that the pawl 11 as a lever with a first arm, which is given by the connection from the axis W to the engagement tip 12 is given, and a second arm, which is given by the extension 14, is given.
- the extension 14 is arranged in a recess 15 of a lever 16, wherein the lever 16 pivotally mounted on the brake lever 2 about the axis W is mounted so that the lever 16 and the pawl 11 are pivotally mounted about the same axis W on the Bremsbeuschitgungshebel 2.
- the spring element 7 is arranged with a second end.
- a latch 17 is provided, which is formed integrally with the Hebei 16, wherein the latch 17 with a arranged on the brake lever 2 projection 18 forms a positive connection, so that the lever 16 on the brake lever 2 is fixed.
- the device 1 is shown for actuating a brake in the transport position, wherein the lever 16 is provided by means of the positive connection of the arranged on the lever 16 bolt and arranged on the brake lever 2 projection 18 is non-rotatable.
- the pawl 11 is fixed in the recess 10, so that the pulley 4 is arranged non-rotatably on the brake lever 2.
- the actuation of the tab 19 releases the positive connection between the latch 17 and the projection 18, with the latch 17 being pulled out below the projection 18. If the positive connection between the integral with the bolt 17 formed lever 16 and the brake lever 2 canceled, the lever 16 is rotated by the spring member 7 about the axis W and the
- the spring element 7 thus tensioned on the one hand the pulley 4 and thus the brake cable 6 and on the other hand acts on the spring element 7, the lever 16 and thus the pawl 11, so that the pawl 1.1 is fixed by means of the engagement tip 12 in the toothing 8.
