The invention relates to a parking brake for a motor vehicle, including a pivotable locking mechanism for applying a retaining force to a parking brake gear. The locking mechanism can lock into the parking brake gear by means of an axially movable first actuation unit. According to the invention, the first actuation unit is designed as a spring-loaded cam follower. The invention also relates to an operating method for locking and unlocking the parking brake.

A lock module assembly controls hill hold, park, and neutral states of a vehicle. The lock module assembly does all of this by controlling rotation of a wheel hub (or a shaft that rotates the wheel hub) of the vehicle. The lock module assembly includes a pocket plate fixedly secured to a rotating shaft. The pocket plate includes a locking element housed therein. A notch plate has first and second sets of notches with the first set complementing the pocket plate secured to the rotating shaft. A second set of notches complements a static pocket plate that houses at least clockwise actuator and at least one counterclockwise actuator. The actuators are used to control hill holds and park, whereas the locking element of the pocket plate disengages the wheel hub from the rotating shaft (neutral).

The present invention relates to an apparatus for engaging a first body with a second body, for example, for locking an oil rig platform to a rig leg. The apparatus comprises a driving portion, for example in the form of a driving wedge, which is moveably attachable to the first body, and an engaging portion, for example in the form of an engaging wedge, which is moveably attached to the driving portion. The driving portion is adapted to move in a first direction with respect to the second body and the engaging portion defines an engaging profile adapted to engage a complementary profile on the second body. Movement of the driving portion results in movement of the engaging portion. The apparatus also comprises an adjustment device connecting the driving portion to the engaging portion and adapted to move the engaging portion independently of the driving portion.

This invention relates to a braking device (10) for a passenger conveyor comprising at least one movable part (12). The braking device (10) comprises a braking element (18) having a braking portion (34) engageable with the movable part (12) of the passenger conveyor. The braking element (18) is movable in a first direction into a position in which the braking portion (34) engages with said movable part (12) of the passenger conveyor. The braking element (18), in a state in which the braking portion (34) engages with the movable part (12) of the passenger conveyor, is movable in a second direction from a position of initial engagement of the braking portion (34) into a braking position of the braking element (18). The movement in the second direction is driven by movement of the movable part (12) of the passenger conveyor.

A safety brake device for a power tool includes a decoupling device, configured to decouple an output unit from a drive unit during a braking operation thereby reducing at least one of a rotational mass and rotational energy of the output unit, and a brake device with a first brake device part and a second brake device part. The first brake device part is arranged on the output unit so as to allow essentially no relative rotation, and the second brake device part is configured to allow essentially no relative rotation with respect to the power tool. The first brake device part and the second brake device part are configured to interact mechanically with one another during a braking operation to stop rotation of the output unit. The first brake device part of the brake device is embodied in one piece with the decoupling device.

A safety brake device for braking a machining tool includes at least one brake device configured as an at least two-part claw clutch. The claw clutch includes a first claw-clutch part, and a second claw-clutch part. The first claw-clutch part is arranged on the output shaft so as to allow no relative rotation, the second claw-clutch part is configured to allow no relative rotation with respect to the power tool, each claw-clutch part has a respective plurality of toothing elements, the respective plurality of toothing elements are configured to engage with one another during a braking operation to stop rotation of the output shaft, and a maximum angular spacing Δmax of mutually adjacent toothing elements of at least one of the first plurality of toothing elements an the second plurality of toothing elements is determined depending on a maximum rotational speed of the output shaft.

A brake device including a brake unit; a contact device engageable by the brake unit and movable relative to the brake unit, wherein the brake unit includes at least one activation device and at least one brake member that includes a transmission member and a brake shoe that is pivotably supported in a pivot bearing at an end of the at least one brake member, wherein the at least one activation device engages the transmission member to move the at least one brake member towards the contact device until the brake shoe contacts the contact device in an activation position of the at least one brake member and the brake shoe, wherein the pivot bearing is arranged at the at least one brake member so that the pivot bearing is movable towards the contact device together with the transmission member.

An overload brake and method for trolley suspended on a flange of a load traveling apparatus girder prevents the displacement movement of a suspended load along a girder by clamping a brake between two symmetrical flange tabs of the girder. The girder is elastically deformed by the load which is applied to the girder by the contact between a surface of the girder and translation wheels that move the load along the girder. Upon sufficient elastic deformation, portions of the girder contact a brake to prevent movement of the load along the girder.

An electromagnetic brake (10) including a plurality of elastic members (25) which are arranged between an engagement surface of a brake pad (13) and an engagement surface of a hub (12) symmetrically about a center of rotation of the shaft (11). The biasing directions of the plurality of elastic members are in a rotational direction of the shaft.

To realize a mechanism that can support an article at a desired position in such a way as to be able to move the article, with a thin, simple configuration. A load support mechanism 1 includes a fixed support section 2, which includes a fixed cam 8; a movable support section 3, which receives a load and can move vertically; a horizontal cam groove 13, which is provided in the movable support section; a cam follower member 15, which can move horizontally along the cam groove; a first spring 4, which is mounted between the fixed support section and the movable support section to support a load; and a second spring 18, which pushes the cam follower member horizontally and presses the cam follower member against a fixed cam surface 9 of the fixed cam. A reaction force of the fixed cam against the cam follower contains a vertical component depending on a height position of the movable support section, and the vertical component assists or reduces the spring's force to push up the load. A cam shape of the fixed cam surface is provided in such a way that the load acting around the cam follower, the spring forces of the first and second springs, and the reaction force applied from the fixed cam are balanced against each other.
