A spring brake system includes a service brake chamber, a spring brake chamber adjacent to the service brake chamber, a wall separating the service brake chamber from the spring brake chamber, a shaft, and a device. The shaft extends from the service brake chamber into the spring brake chamber through an opening in the wall. The device is disposed along the shaft through the wall, the device being configured to: i) allow air to flow from the service chamber into the spring brake chamber, and ii) prevent air from flowing from the spring brake chamber into the service chamber. The air is within a range that is sufficient to reduce a pressure differential between the service brake chamber and the spring brake chamber. The air is also within a range that is sufficient to generate an anti-compounding effect.

The invention relates to a dynamic force-distributing device. The dynamic force-distributing device has a dynamic three-stage force distribution function, and is especially suitable for being applied to a single-handed braking device of various front and rear wheel form vehicles. The whole braking process can show three-stage functional characteristics such as safety, stability, reliability, fast stopping and the like, so that the problem of accidents caused by improper brake operation is avoided.

The present disclosure relates to an engagement structure of a push rod guide and a push rod guide cover of a brake chamber for a vehicle, in which a pair of semi-circular, hingedly connected, half members in a shape of a plate are assembled at a side surface of axial direction of the push rod into a shape of a disk, a push rod opening is formed at the center of the disk to guide a movement of the push rod, a protrusion projecting upwards is provided at a central part of the push rod guide, forming a step in a radial direction of the push rod guide, and a receiving groove corresponding to the step is formed on an inner circumferential surface of the push rod guide cover and is connected to the step.

A spring brake actuator (2) for use in a commercial vehicle includes a cylinder housing (4) including a spring brake piston (10) for applying a braking force, a spring guide (12) attached to the spring brake piston (10). The spring guide (12) includes a valve (14) and a retaining device (16) for retaining the valve (14). The retaining device (16) includes a basic body (34) and clamping portions (36) for clamping the retaining device (16) to the spring guide (12). The clamping portions (36) are arranged at the basic body (34) along a circumference (38) thereof, and the clamping portions (36) are spaced apart from each other forming slits (40) between the clamping portions (36) to allow for a circulation of air through the slits (40).

An electromechanically drivable brake pressure generator for a hydraulic brake system of a vehicle. The brake pressure generator including a spindle drive unit for converting a rotary movement on the drive side into a translational movement for the purpose of actuating a piston of a hydraulic piston-and-cylinder unit. A gear unit is arranged between the spindle drive unit and an electric drive motor. A drive motor axis and an axis of the spindle drive unit are arranged radially offset from one another. The piston-and-cylinder unit and the electric drive motor are arranged on axially opposite sides of the gear unit.

A brake release mechanism for a spring brake actuator includes a brake release bolt having a threaded portion, a running engaging the threaded portion, the running nut being adapted to axially travel along the threaded portion in order to move a spring brake actuator piston against a force of an actuator power spring, an indicator device comprising an indicator pin being at least partially accommodated in a receiving space of the release bolt, wherein the indicator device further comprises a pin actuator for axially moving the pin relative to the receiving space. It is proposed according to the invention that the pin actuator comprises an indicator cap being attached to the pin, the indicator cap comprising a basic body and at least one spacing element being attached to the basic body, the spacing element being configured to abut against the running nut.

A control system includes a plurality of request generation devices each of which outputs first and second requests based on a request generated by at least one application, an arbitrator that arbitrates the first and second requests and that outputs a single first request and a single second request, and a control apparatus that controls an actuator based on a final request obtained by arbitrating the first and second requests from the arbitrator and a request made by a driver. The arbitrator specifies the request generation device that has output a request corresponding to the final request based on the final request, the self-output first request, and the self-output second request. The request generation device specified by the arbitrator specifies the application that has generated the request corresponding to the final request based on the self-output first request, the self-output second request, and the request made by the driver.
