A parking valve for manually actuating a spring-loaded parking brake, includes: a housing with a port that can be fluidically connected to a release chamber of a spring-loaded brake cylinder, a port that can be fluidically connected to a brake supply reservoir, and a ventilation port; a slide for manual actuation and which can be moved along a full section between two end positions inside the housing. The slide assumes positions along the full section, in which, as a result of at least one seal, there is no fluidic connection between the port to the release chamber and the ventilation port, and assumes other positions along the full section, in which, as a result of the at least one seal, there is no fluidic connection between the port of the release chamber and the port to the brake supply reservoir. A blocking device acts on the slide during movement at least along a partial section of the full section in at least one direction, with a continuously variable counterforce dependent on the position of the slide on the partial section.

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 invention relates to an arrangement (1) for assisting a parking brake (10), which parking brake (10) comprises a brake lever (12) which is supported in a carrier device (14) such that it is pivotable between a release position and a locking position and is able to be coupled to a braking system by means of a transmission means. The arrangement (1) comprises a lifting element (20) with an energy storage unit (22), which is operatively connected to the brake lever (12). The operative connection comprises a redirecting element (30) which is supported in a way pivotable about a pivot axis (32) and is arranged in such a way that the redirecting element couples the lifting element (20) to the brake lever (12).

A device designed for controlling and regulating an electro-pneumatic parking brake circuit includes a manual controller configured to actuate a parking brake via the electro-pneumatic parking brake circuit, the manual controller having a first circuit arrangement and a second circuit arrangement, the first circuit arrangement being a digital, bidirectional circuit arrangement and the second circuit arrangement being an analog circuit arrangement. The device further includes control electronics electrically connected to the manual controller. The first circuit arrangement is connected to the control electronics via a first connection cable and the second circuit arrangement is connected to the control electronics via a second connection cable. The first connection cable is a digital data transmission channel configured to enable a digital data transmission between the digital circuit arrangement and the control electronics. The second connection cable is an analog data transmission channel configured to enable an analog data transmission.

A parking brake control device, including: a base attached to the vehicle body; a lever body rotatable with respect to the base and including a tubular handle portion; a ratchet gear formed on the base; a pawl rotatable with respect to the lever body and engaging with the ratchet gear to regulate rotation of the lever body; a release knob protruding from an end of the handle portion; a compression coil spring positioned inside the handle portion, the spring having a first end and a second end, wherein the compression coil spring at the first end urges the release knob outward of the handle portion; and a release rod inserted through the compression coil spring, with one end attached to the release knob, and another end connected to the pawl, wherein pushing in the release knob causes the release rod to rotate the pawl to disengage from the ratchet gear.

A sealing element for sealing a pressure chamber is provided in a master cylinder for a clutch or brake system. The sealing element has a sealing lip for sealing a feed of hydraulic fluid from a reservoir mounted on a housing of the master cylinder into the pressure chamber and has a sealing structure for sealing the pressure chamber from the surroundings of the pressure chamber.

The present disclosure relates to an integrated control apparatus for an autonomous driving vehicle, in which operation for accelerating, braking, and steering of a vehicle is implemented through one integrated lever and buttons for starting and shifting of a vehicle are disposed on one case together with the integrated lever. Accordingly, the integrated control apparatus can be easily used for an autonomous driving vehicle.

A steering wheel assembly having a braking function, including: a steering wheel, a steering shaft, and a controller. The steering wheel is connected to one end of the steering shaft. The steering wheel includes a rim body and spokes. The rim body is connected to the steering shaft via the spokes. A force sensor, a photoelectric sensor, a mechanical wave sensor or a switch are provided between the rim body and the spokes, or provided on one side of the rim body away from a driver, or provided between the spokes and the steering shaft, or provided on the steering shaft, and are connected to the controller. The controller is connected to a braking system.

One or more sets of dual brake pads and related assemblies are disposed over and upon one or more wheels of an inline skate. One or more center assemblies are above each brake enabled wheel and center over each wheel. A brake assembly may be secured to a skate boot or to the frame of an inline skate. A brake assembly may attach to a hand control braking system enabling foot free braking. A brake assembly may be attached to one or more center wheels of an inline skate so as to not impede skating maneuvers.
