摘要： A spring brake actuator has a combined housing including a first housing, a second housing, and connection part connecting the first housing and the second housing. Gas inlet ports are disposed along the circumference of the combined housing in a gas inlet port section. A mechanical connection section is disposed in the same axial space as the gas inlet portion section. A bayonet connection is arranged in the mechanical connection section, with gas inlet ports disposed between the bayonet elements. Port connectors may extend through recesses or holes and be threaded into the gas inlet ports, and which may block the bayonet connection and block relative rotation between the first and second housings. The connection part may include a ring shaped protrusion form fit with a protruding of the second housing, with the bayonet elements disposed at the opposite end of the connection part engaged with the first housing.

摘要： A brake force generator for a brake system. The brake force generator includes a driveshaft rotatably mounted in a housing, an electric motor, a displaceably mounted actuating element, and a transmission device that acts between the driveshaft and the actuating element in such a way that when there is a rotation of the driveshaft the actuating element is displaced. The transmission device has a planetary gear mechanism that has a sun gear connected in rotationally fixed fashion to the driveshaft, a rotatably mounted planet carrier, and at least one planet gear that is rotatably mounted on the planet carrier by a planet gear shaft. The planet carrier has a hollow shaft segment, and a jacket wall of the hollow shaft segment having a radial through-opening in which the planet gear lies. The planet gear shaft is mounted in the hollow shaft segment at both sides of the planet gear.

摘要： A multi-disc brake includes an annular brake coil holder with a wound brake coil, an armature plate with a disc support to which a multiplicity of armature plate discs is fastened. A compression spring brings about a linear spacing of the brake coil holder from the armature plate made of a ferromagnetic material in a braking position of the multi-disc brake and, when current is applied to the brake coil, a released position of the multi-disc brake can be created by attracting the armature plate in the direction of the brake coil holder. The braking effect results from the interaction of the armature plate discs with drive shaft discs on a drive shaft. The brake coil holder area of the brake coil holder and the cross-sectional area of the brake coil are substantially of rectangular single-legged design, and when installing the multi-disc brake, part of the wall of the drive support surrounds the brake coil on two sides and the brake coil holder on one side.

摘要： A motion conversion mechanism of a brake device includes a rotation member and a linear motion member that linearly moves accompanying the rotation of the rotation member. The rotation member is rotationally driven through a third gear. A male screw and a female screw mesh with each other on the side opposite to the brake shoe of the third gear, where one end of an actuating member receives a force for actuating the brake shoe from the linear motion member, and the other end actuates the brake shoe. The guide member that guides the actuating member is made of a material different from that of the rotation member, and slidably guides the actuating member in the axial direction.

摘要： A twin piston caliper with an electric parking brake and method of operating such a twin piston caliper with an electric parking brake. The twin piston caliper housing comprises two separate inner brake pads for each of the two pistons; one outer brake pad at the outer housing finger area; an electric parking brake mechanism configured to be incorporated in between the two pistons so that it is not embedded in the hydraulic piston and not the hydraulic brake fluid; and wherein the electric parking brake mechanism uses its own electric parking brake friction brake pad to clamp against the brake rotor. The method of operating the twin piston caliper with the electric parking brake comprising the following steps: using hydraulic pressure, preferably high pressure overlay, to clamp up inner brake pads and the outer brake pad against a brake rotor; applying the electric parking brake mechanism to clamp an electric parking brake friction brake pad against the brake rotor; releasing the hydraulic pressure to unclamp the two inner brake pads whereby the electric parking brake mechanism maintains the clamp between the outer brake pad and the electric parking brake friction brake pad.

摘要： An electric parking brake system includes a wheel driven by an electric motor to move a vehicle, a parking brake maintaining the wheel stopped, a parking brake actuator operating the parking brake, and a drive controller controlling the parking brake actuator. The drive controller controls the electric motor to maintain the wheel of the vehicle stopped while the vehicle is parked, and calculates a parking torque based on a control amount of the electric motor that maintains the wheel stopped. The drive controller calculates a necessary braking force for the parking brake to maintain the wheel stopped based on the calculated parking torque, and controls the parking brake actuator so that the necessary braking force is generated.
