ELECTOMECHANICAL BRAKE ACTUATOR WITH VARIABLE SPEED EPICYCLIC GEARBOX
An electromechanical actuator is provided comprising a housing, a rotor disposed in the housing, an selective gearbox mechanically coupled to the rotor and disposed in the housing, a first output of the selective gearbox configured to rotate at a different speed than the rotor, and a second output of the selective gearbox configured to rotate at a same speed as the rotor.

Actuator assembly for a parking brake system
Disclosed is an assembly that includes a spindle; a brake cable in communication with the spindle; and a spring in communication with the spindle. Movement of the spindle in a first direction causes the brake cable to move so that a clamping force is created. Movement of the spindle in a second direction causes the brake cable to move in a second direction so that the clamping force is released. Movement of the spindle in both the first direction and the second direction causes the spring to compress so that a controller can determine when the clamping force is created and released.
Bicycle rim brake
A bicycle rim brake comprises a first brake arm, a second brake arm, and a pivotal cam member. The first brake arm is configured to pivot about a first pivot axis. The first brake arm includes a first mounting portion and a first follower. The second brake arm is configured to pivot about a second pivot axis which is different from the first pivot axis. The second brake arm includes a second mounting portion and a second follower. The pivotal cam member is configured to pivot about a third pivot axis which is different from the first pivot axis and the second pivot axis to guide the first follower and the second follower so that the first brake arm pivots about the first pivot axis and the second brake arm pivots about the second pivot axis.
INSULATING DEVICE FOR A BRAKE ACTUATING LINKAGE
Insulating device for a brake actuating linkage, with a cylindrical insulating or damping bushing which comprises an inner cylinder sleeve, an outer cylinder sleeve coaxially surrounding the inner cylinder sleeve so as to form an annular gap, and an elastic element which fills the annular gap and is fixedly connected to the two cylinder sleeves, with a brake-pedal-side linkage section and a brake-valve-side linkage section, the two linkage sections engaging the insulating bushing along their cylinder axis on opposite sides such that the elastic element is sheared reversibly under the action of an increasing actuating pressure applied to the linkage sections by parallel displacement of the two cylinder sleeves in relation to each other until a mechanical end stop limiting the parallel displacement is reached.

Force generating device, in particular for a parking brake, method for operating the device and system having the device
A device for generating a force applied to a component includes a force generating element supported on a resilient support device having first and second, or only a second, spring elements in series in a force transmission chain being stressed during force transmission. The first spring element is less stiff than the second. The first spring element is stressed by a first supporting force over a first spring travel. A spring travel exceeding the first spring travel and a force absorption by the first spring element exceeding the first supporting force are prevented by a first mechanical engaging device. The second spring element is formed by a spring module having a second spring stressed by a second mechanical engaging device with a second supporting force permitting the second spring to only be further stressed when exceeding the second supporting force. A travel sensor detects displacement of the force generating element.
Parking brake apparatus and control method thereof
A parking brake apparatus may include: a motor unit; a driving unit operated by the motor unit; a nut screw rotated by the driving unit; a bolt screw coupled to the nut screw so as to pass through the nut screw, and moved in a longitudinal direction inside the nut screw in connection with the rotation of the nut screw; a cable having one side connected to the bolt screw; a hook part connected to the other side of the cable; and a boot part having an internal space in which the cable and the hook part are moved in the longitudinal direction, and including a stopper arranged on a moving path of the hook part so as to restrict the movement of the hook part.
Support arrangement with activation mechanism
A support arrangement having an activation mechanism to control the movement of wheels is provided. The support arrangement includes a platform, a chassis attached to the platform, a pair of wheel assemblies movably coupled to the chassis, and the activation mechanism. The pair of wheel assemblies are operable between a first state and a second state. The activation mechanism includes a track having a first stable position and a second stable position spaced along a length of the track, and a pin configured to travel along the track. Wheels are in the first state when the pin is in the first stable position and are in the second state when the pin is in the second stable position.
Electric parking brake having a gearing unit
A gearing unit of a motor vehicle actuator, in particular an electric parking brake, includes a gearing housing in which a driven first shaft and a driving second shaft having fixed rotational axes are located. A first toothed wheel is mounted on the first shaft and a second toothed wheel is mounted on the second shaft. The first toothed wheel and the second toothed wheel engage with one another through a third toothed wheel. The housing for the third toothed wheel has at least two spatially offset bearing points in order to adjust a transmission ratio between the first shaft and the second shaft. An electric parking brake having a gearing unit is also provided.
