A clutch includes balls, an axle, a socket and a cylinder. The axle includes a circular section formed with alternate cavities and ridges. The socket includes a circular bore for receiving the circular section of the axle and apertures for receiving the balls. The cylinder includes an annular recess made in an internal face. The socket is movable in the cylinder between two positions. When the socket is the first position, the internal face of the cylinder abuts the external portions of balls to engage the internal portions of the balls with the ridges to cause the axle to rotate the socket via the balls. When the socket is in the second position, the annular recess receives the external portions of the balls to allow disengagement of the internal portions of balls from the ridges to allow the axle to rotate relative to the socket.

The present disclosure relates to an electronic brake system. The electronic brake system includes a reservoir in which a pressurized medium is stored, an integrated master cylinder having a master chamber and a simulation chamber, a reservoir flow path provided to communicate the integrated master cylinder with the reservoir, a hydraulic pressure supply device provided to generate a hydraulic pressure by operating a hydraulic piston according to an electrical signal output in response to a displacement of the brake pedal, a hydraulic control unit including a first hydraulic circuit provided to control the hydraulic pressure to be transferred to two wheel cylinders, and a second hydraulic circuit provided to control the hydraulic pressure to be transferred to the other two wheel cylinders, and an electronic control unit configured to control valves based on hydraulic pressure information and displacement information of the brake pedal.

An anti-rotation banjo connection comprising a banjo plate attached to a pipe at its own first end edge and including an opening configured to receive a bolt, the bolt being configured to be screwed into a port of a hydraulic component, wherein a second end edge of the banjo plate, opposite to the first end edge, is provided with a positioning notch configured to partially surround a stopping fastener when the bolt is screwed into the port, whereby an edge wall delimiting the positioning notch is configured to interfere with the stopping fastener preventing the banjo plate from rotating about the bolt.

Disclosed is a caliper brake including a carrier on which a pair of pad plates are installed to advance and retreat, a caliper housing slidably installed on the carrier and provided with a cylinder, a piston installed in the cylinder and provided to advance and retreat toward the pad plates by braking hydraulic pressure, a seal groove formed to be annularly recessed into an inner surface of the cylinder, and a ring-shaped seal member in close contact with an outer surface of the piston and accommodated in the seal groove, wherein the seal groove includes a bottom surface with which an outer circumferential surface of the seal member is in close contact, a first surface facing a front surface of the seal member, a second surface facing a rear surface of the seal member, and a bent surface in contact with the bottom surface and the second surface and provided in an arc shape.

In caliper seal structure, region on one side of caliper main body in axial direction of cylinder with respect to piston seal is set as fluid pressure side where fluid pressure is received, region on other side of caliper main body in axial direction of cylinder with respect to piston seal is set as atmospheric side that opens to atmosphere, and groove forming portion includes holding portion that sets groove width of seal groove in axial direction as first groove width and that is configured to hold piston seal by making inner side surfaces of seal groove in axial direction contact with outer side surfaces of piston seal in axial direction, respectively, and enlarged portion that sets groove width of seal groove in axial direction as second groove width which is increased to one side in axial direction so as to be greater than first groove width.

The present invention relates to an anti-drag structure of automobile brake calipers, comprising a brake caliper body which is provided with a cylinder bore and a brake claw arranged along the axis of the cylinder bore in an extending mode; and a cylindrical piston bush is pressed in the cylinder bore by interference fit, a step ring groove is formed in the inner wall of the piston bush and composed of a major diameter ring groove and a minor diameter ring groove which have rectangular sections. The present invention can improve the generality of the brake caliper body through the arrangement of the piston bush and improve the standardization of production manufacturing of brake calipers, and can reduce the residual drag moment of the brake caliper and the fuel consumption with the rubber seal ring and the phenolic resin PF ring to achieve the purpose of emission reduction.

A conducting element for conducting a pressurized fluid and for conducting a cooling fluid, as well as a hybrid module and a drive assembly having a hybrid module are provided. The conducting element for conducting a pressurized fluid for hydraulically actuating a clutch unit and for conducting cooling fluid for cooling a clutch unit has a cylindrical section and a securing section. At least one pressurized fluid channel is formed in the securing section for transporting pressurized fluid. The conducting element also has at least one cooling fluid channel which has at least one axial direction component in the cylindrical section, wherein the flow line element is fluidically connected to the cooling fluid channel for supplying a clutch unit and/or electric machine with cooling fluid. With this embodiment of the conducting element, a possibility for fluid conducting is created which combines the transport of cooling fluid and pressurized fluid in a fluidically separated manner and with limited axial installation space.
