Definitions
- the present invention relates to an electric parking brake with an improved interface between a caliper and a drive for actuating the parking brake.
- Torque transmission impairments lead, as they significantly reduce the efficiency and fatigue strength, as well as have sealing problems between the caliper and the engine-gear unit.
- the electric parking brake with the features of claim 1 has the advantage that it performs a radial centering between a caliper and a motor-gear unit only via torque transmitting parts with a simple structure and simple, cost-effective installation. Therefore, no overdetermination for the
- a spindle is axially directly connected to an output shaft of the motor-gear unit.
- the spindle is centered on the output shaft and mounted in a brake caliper.
- an interface between the caliper and the motor-gear unit can be realized by a direct connection of the spindle to the output shaft and bearing the spindle in the caliper.
- a distortion of the components during assembly of the gear unit on the brake caliper can be avoided due to unfavorable tolerance additions.
- the spindle is mounted radially and axially in the caliper by means of a bearing.
- the motor-gear unit can be stored directly via the output shaft and the spindle centric to an axial direction.
- the attachment of the engine-transmission unit on the caliper is preferably carried out via
- the output shaft preferably comprises a projecting end portion which engages in a central opening in the spindle.
- a positive connection is preferably provided between the output shaft and the spindle.
- the positive connection is preferably a toothing or alternatively also a square connection or multi-corner connection.
- a sealing element is further provided, which seals a gap extending in the radial direction, wherein the sealing element has a sealing surface directed in the axial direction.
- a defined sealing surface can be provided in the axial direction, which seals between the caliper and the motor-gear unit.
- the electric parking brake according to the invention has a corrosion relief groove, which avoids the occurrence of crevice corrosion at the radial sealing gap.
- the corrosion relief groove is radially outside the
- a sealing element according to the invention preferably an elastic O-ring or a liquid seal or a hose ring section is used. In this case, other types of seals are possible.
- a groove for receiving the sealing element is preferably provided in the caliper.
- this groove can also be formed in a housing component of the motor-gear unit.
- the housing component of the motor-gear unit is rotatably connected to the caliper by means of a rotation.
- the anti-rotation comprises in particular an axially projecting pin and a correspondingly formed recess.
- the pin may be provided either in the caliper or in the housing component of the motor-gear unit. Accordingly, the correspondingly formed recess is then provided in the opposite component.
- Figure 1 is a schematic sectional view of an electric parking brake according to an embodiment of the invention.
- the electric parking brake 1 comprises a motor-gear unit
- the engine-transmission unit 2 includes a - A - compact electric motor and a gearbox, which includes several gear elements.
- the engine-transmission unit 2 further includes an output shaft 3, at which an output torque is output.
- the output shaft 3 is arranged in an axial direction XX of the electric parking brake 1.
- a region 3a is formed with a smaller diameter.
- a toothing 3b is provided, which is in engagement with a toothing 5b of a spindle 5.
- the toothing 5b is in this case formed in an axial central Ausappeluung 5a of the spindle 5 complementary to the toothing 3b.
- the spindle 5 is part of a spindle device 4, which further comprises a nut 6.
- the spindle 5 is mounted via a bearing 9 in a brake caliper 7 concentric with the central axis X-X.
- the bearing 9 is arranged radially outside the connection between the spindle 5 and the output shaft 3.
- the caliper 7 is adjacent to a housing member 8 of the motor-gear unit 2, whereby, as can be seen from Figure 1, a directed in the radial direction gap between the
- housing member 8 and the caliper 7 is formed.
- annular groove 7a for receiving a seal 10 is provided in the caliper 7.
- the seal 10 in this embodiment is an O-ring seal.
- a corrosion relief groove 11 is formed at a position slightly radially outside the groove 7a, which is also provided annularly circumferentially.
- the Korrosionsentlastungsnut 11 has the task of a forced
- a pin 12 protruding in the axial direction XX is also formed on the housing component 8.
- an axial recess 13 is provided in the form of a bore in the caliper 7.
- the reference numeral 14 denotes an electrical plug connection to the engine-gear unit.
