A brake module for a drive system, in particular for doors, including at least one thrust washer and at least one brake disc, wherein the at least one thrust washer and the at least one brake disc each have at least one friction surface rubbing against each other during braking operation is provided. The embodiments also relate to a drive system, in particular for doors, including such a brake module. The embodiments further relate to a production method for a brake module of the abovementioned type. Known brake modules have a high variation in the braking force on the one hand in the course of their service life and on the other hand as a function of the temperature.

An attachment structure is a structure that attaches an annular brake disk to an attachment object member that is a wheel or a disk body of a railway vehicle. The attachment structure includes a fastening member and an elastic member. The elastic member is disposed between a nut of the fastening member and the brake disk. The elastic member has a member body having a tubular shape, and a flange. The flange is connected to an end part on the nut side among two end parts of the member body. The flange protrudes outward from the member body and contacts an outer peripheral portion of the nut.

The present disclosure relates to the positioning of a disc brake caliper mounted to a rigid bicycle fork. In one aspect, the disc brake caliper is attached to a portion in front of the fork and the front wheel axle, hence exposing the disc brake caliper to the maximum cooling potential of the airflow. Further, the disc brake caliper is positioned roughly horizontally in-line with the wheel axle to provide aerodynamic benefits for the trailing front wheel axle.

A radial mounting torque plate for mounting a disk brake component for heavy-duty vehicles, the torque plate comprising an annular portion and a pair of mounting arms. The annular portion is formed with an opening for receiving an axle of the heavy-duty vehicle. The mounting arms are integrally formed with and extend longitudinally outward in opposite directions from the annular portion and have a T-shaped cross-section.

A thermal management system includes a shaft extending along an axis and configured to rotate in at least one of two different directions about the axis, and a brake system operably coupled with the shaft. The brake system controls a speed of rotation of the shaft in the at least one of the different directions. A first fan structure is operably coupled with the shaft and disposed on a first side of the brake system, and a second fan structure is operably coupled with the shaft and disposed on a second side of the brake structure. One of the first or second fan structures is configured to direct fluid toward the brake system and the other of the first or second fan structures is configured to direct at least some of the fluid away from the brake system to control a temperature of the brake system.

A carrier pot for a brake disc includes a radially inner hub ring portion for fastening to a wheel axle, a radially outer brake disc ring portion for fastening to the brake disc, and at least one electric/electronic functional component. The carrier pot is made from a fiber-plastic composite and the at least one electric/electronic functional component is integrated into the fiber-plastic composite.

A braking system for a portal lift assembly includes a shaft operably connected to a vehicle power source and effective to directly or indirectly rotate a wheel of the vehicle upon rotation of the shaft about its axis, a piston positioned along the shaft and effective for applying an axial force along the axis of the shaft, a fluid channel fillable with a non-compressible fluid and effective to apply a hydraulic force to the piston when pressure is applied to fluid in the line, a pressure plate positioned along the shaft and effective for applying an axial force along the axis of the shaft in response to the application of an axial force by the piston. A clutch pack is positioned between the pressure plate and the piston, and includes two sets of clutch plates radially surrounding the shaft. The first set of clutch plates is connected to the shaft in a manner effective to cause those clutch plates to rotate about the axis of the shaft when the shaft rotates. The second set of clutch plates is prevented from rotating about the axis of the shaft. Members of the first set of clutch plates are interspersed between members of the second set of clutch plates, so that when the clutch pack is sufficiently compressed by axial forces applied by the piston and the pressure plate, the first set of clutch plates is forced against the second set of clutch plates so that friction forces between members of the first set of clutch plates and members of the second set of clutch plates slow and may subsequently stop the rotation of the shaft.

A brake assembly has a wheel body, a first stopping device, and a second stopping device. The wheel body has a central axle and two engaging portions formed respectively on two ends of the central axle. The first stopping device is connected with the engaging portions of the wheel body and has a resilient member and a magnetic unit. The resilient member is C-shaped and has a lateral rod and an inclined rod connected integrally with an end of the lateral rod. The magnetic unit is mounted on the lateral rod of the resilient member and has a sleeve having a bottom opening and a magnetic element mounted in the sleeve and selectively abutting the wheel body. The second stopping device is connected securely with the lateral rod of the resilient member and is engaged selectively with the engaging portions of the wheel body.

A thermal management system includes a shaft extending along an axis and configured to rotate in at least one of two different directions about the axis, and a brake system operably coupled with the shaft. The brake system controls a speed of rotation of the shaft in the at least one of the different directions. A first fan structure is operably coupled with the shaft and disposed on a first side of the brake system, and a second fan structure is operably coupled with the shaft and disposed on a second side of the brake structure. One of the first or second fan structures is configured to direct fluid toward the brake system and the other of the first or second fan structures is configured to direct at least some of the fluid away from the brake system to control a temperature of the brake system.

A brake disc configured to control airflow through portions of a brake disc assembly includes a brake disc, at least one airflow restrictor, and an actuator. The at least one airflow restrictor includes at least one gate member configured to move between a closed position and an open position. In the closed position, the at least one gate member at least partially reduces airflow between a circumferential inner edge and a circumferential outer edge of the brake disc. In the open position, the at least one gate member is positioned to permit increased airflow between the circumferential inner edge and the circumferential outer edge of the brake disc, relative to when the at least one gate member is in the closed position. The actuator is coupled to the at least one airflow restrictor and configured to move the restrictor between the open position and the closed position.
