Definitions

  • the invention relates to an actuating device for a parking brake according to the preamble of claim 1.
  • Such an actuating device is known for example from DE 10 2005 013 475 AI.
  • This actuating device comprises a handbrake lever pivotally mounted on a bearing block, a fixing device which has a blocking segment fixed on the bearing block and a movably mounted pawl, and an actuating linkage guided in the handbrake lever which can be actuated by means of a pushbutton against the spring force of a spring.
  • the actuating linkage has for coupling to the pawl on a web, wherein in a locking position of the pawl it is fixed by means of the spring force of a pawl spring on the locking segment, while the web rests against a segment of the locking segment facing edge of the pawl.
  • a force acting against the spring force of the pawl spring force is exerted by means of the push button through the web on the pawl, through which the pawl is released from the locking segment.
  • a disadvantage of this actuating device is, as with corresponding known actuating devices of this type, that the movement of the actuating linkage must be converted into a pivoting movement of the pawl.
  • the pawl is this purpose generally rotatably mounted on a rotary bearing.
  • the provision of this pivot bearing generally requires additional parts, which entails an undesirable cost. This cost is further increased by the fact that the additional parts of this Drehlage- assembled and mounted on the handbrake lever.
  • Also provided at the front end of the handbrake lever push button and its coupling to the actuating linkage requires considerable design effort.
  • the invention has for its object to provide an actuator of the type mentioned, in which a high functionality is given with reduced design effort.
  • the invention relates to an actuating device for a parking brake and comprises a pivotally mounted on a bearing block handbrake lever, at the free end of a handle is provided. With a fixing device of the handbrake lever can be fixed in a pivot position on the bearing block.
  • the handle forms an actuating element by means of which the fixing of the handbrake lever on the bearing block can be canceled.
  • the basic idea of the invention is therefore to release the fixing device of the actuating device by actuating, that is to say moving the handle on the handbrake lever.
  • actuating that is to say moving the handle on the handbrake lever.
  • the previously exclusively used concept of known actuators to release the fixing device by pressing a push button at the front end of the handbrake lever so as to operate the parking brake can be abandoned.
  • the actuating device according to the invention advantageously, according to known actuators of this type, as fixing a stationary mounted locking segment with a toothing and this movably mounted pawl, being fixed by engagement of the pawl on the teeth of the locking segment of the handbrake lever.
  • An essential aspect of the invention is that the movement of the handle can be implemented in a simple manner on the pawl, so that in general the structural means for the movable mounting of the pawl are considerably simplified, whereby the design complexity for the entire actuator considerably can be reduced.
  • the fixing device is achieved by a linear movement of the handle on the handbrake lever.
  • the linear movement of the handle is converted into a linear movement of the locking pawl.
  • the linear movement of the handle is advantageously implemented without deflection in a linear movement of the pawl.
  • a coupling means is guided in the handbrake lever, which transmits the linear movement of the handle on the pawl.
  • the coupling means is a rod, a rope or a Bowden- train.
  • the grip on the handbrake lever is pushed to the rear or pulled forward to actuate the fixing device.
  • the pawl Since in contrast to known actuating devices, the pawl is no longer moved with a pivoting movement on the blocking segment or moved away from it, but according to the invention with a linear movement, results in a further advantage that the pawl may have not only one, but a plurality of ratchet teeth, which can be brought into engagement with the toothing of the locking segment. As a result, the grip of the pawl on the locking segment is considerably improved in its detent position.
  • the fixing device is released by a rotational movement of the handle.
  • the handle for releasing the fixing device is rotated.
  • the rotational movement of the handle is then implemented via coupling means in a movement, in particular linear movement of the pawl.
  • Figure 1 Components of a first embodiment of the inventive actuating device.
  • FIG. 2 Handbrake lever with handle of the actuating device according to FIG. 1 mounted thereon.
  • Figure 3 Components of a second exemplary embodiment of the invention B etuschistsvorraum.
  • Figures 1 and 2 show the essential components of a first embodiment of the actuator 1 according to the invention for a parking brake of a motor vehicle.
  • the actuating device 1 has a hand brake lever 2 and a bearing block 3.
  • the handbrake lever 2 has a tubular receptacle 4, which is assigned to two bores 5 in the bearing block 3, wherein in each case a bore 5 in a leg 3a of the bearing block 3 is arranged.
  • These legs 3a extend parallel to each other at a distance and each open at a right angle from the bottom part 3b of the bearing block 3.
  • the handbrake lever 2 By means of a shaft, not shown, or the like, which is inserted into the tubular receptacle 4 of the handbrake lever 2 and into the bores 5 of the bearing block 3, the handbrake lever 2 can be pivoted on the bearing block 3 about a horizontal axis.
  • the respective pivot position of the hand brake lever 2 is transmitted via a tie rod, not shown, to the likewise not shown parking brake of the motor vehicle, in which the B etuschistsvortechnisch 1 is installed.
  • a fixing device For fixing the handbrake lever 2 in a predetermined pivot position, a fixing device is provided.
  • This fixing device comprises a mounted on the bearing block 3 and fixedly connected to this locking segment 6, which has a toothing with an array of teeth in a known manner.
  • a pawl 7 is provided on the hand brake lever 2.
  • This pawl 7 is slidably mounted on opposite sides in receiving grooves 8 of the hand brake lever 2 in the longitudinal direction. At its end projecting beyond the receiving grooves 8, the pawl 7 has three latching teeth 7a which are adapted in their geometries to the teeth of the blocking segment 6, so that they can latch into place there.
  • a pivotal position of the handbrake lever 2 is fixed by the pawl 7 is pressed against the locking segment 6 with a contact pressure, which is generated for example by a not shown, acting on the pawl spring element 7, so that the locking teeth 7a of the pawl 7 firmly engage the toothing.
  • a Bowden cable 9 is coupled to the latching teeth 7a opposite end of the pawl 7 as a coupling means.
  • the Bowden cable 9 extends in a laterally on the handbrake lever 2 exposed guide, the lateral boundaries in the form of two rail segments 10, which is formed integrally with the handbrake lever 2 having. Also integrally formed guide elements 11 are provided between the rail segments 10, which enclose the Bowden cable 9 in a clamp shape, so that it is guided in the guide elements 11 with low backlash.
  • the visible in Figure 1 free end 9a of the Bowden- train 9 is coupled to a handle 12 which is placed on the rod-shaped front end of the handbrake lever 2.
  • the handle 12 is displaceably mounted in the longitudinal direction of the front end of the hand brake lever 2, that is, the handle 12 can perform a linear movement on the hand brake lever 2.
  • the handle 12 is pulled by an operator on the hand brake lever 2 forward.
  • This linear movement is transmitted via the Bowden cable 9 as a coupling means directly and without deflection on the pawl 7, so that the pawl 7 also performs a linear movement and is pulled away with this linear movement of the locking segment 6.
  • the handbrake lever 2 can be pivoted on the bearing block 3.
  • FIG. 3 shows a second exemplary embodiment of the actuating device 1 according to the invention.
  • This actuating device 1 also comprises a bearing block 3 and a handbrake lever 2, which is pivotally mounted on the latter and is shown in a partial representation in FIG. Analogous to the embodiment according to FIGS. 1 and 2, the bearing block 3 again consists of a bottom part 3b with two legs 3a which open out perpendicularly therefrom.
  • the hand brake lever 2 a tubular receptacle 4 and the bearing block 3 has two holes 5, in which a shaft, not shown, or the like can be introduced.
  • the fixing device of the actuating device 1 consists again of a toothing having a locking segment 6, which is fixedly connected to the bearing block 3, and a pawl 7 with a plurality of locking teeth 7 a, which is mounted on the hand brake lever 2.
  • a rod 13 is slidably mounted in the axial direction in the present case as a coupling means in the hand brake lever 2.
  • a driver 14 is provided, which couples the rod to the pawl 7.
  • the opposite end of the rod 13 is connected to an in Figure 2 not shown handle 12 coupled, which is mounted on the hand brake lever 2 and is slidably mounted on this in the longitudinal direction, that is, the handle 12 can perform a linear movement on the hand brake lever 2.
  • the handle 12 In order to release the pawl 7 from the locking segment 6, the handle 12 is pulled on the hand brake lever 2 to the rear in the present case. Thereby, the rod 13 is moved in the same direction. This movement is transmitted by the driver 14 on the pawl 7, so that it is pulled away from the locking segment 6 and thus the locking teeth 7a of the pawl 7 are no longer in engagement with the teeth of the locking segment 6. So that the pawl 7 executes an exactly linear movement, this is guided in guides 15, which are part of the handbrake lever 2. After releasing the pawl 7 from the locking segment 6, the handbrake lever 2 can be pivoted to the desired position. As soon as the desired position has been reached, the operator lets go of the handle 12 and the pawl 7 engages automatically with its ratchet teeth 7a on the teeth of the blocking segment 6.
