An electro-hydraulic control unit for a vehicle brake system includes a hydraulic control unit including an HCU block defining a motor bore containing an electric motor and an eccentric chamber containing a rotating eccentric driven by the electric motor. The HCU block also defines a pump bore containing a piston pump including a piston rod having a generally cylindrical shape with a smooth exterior surface extending substantially its entire length. An end cap is press fit around an end of the piston rod and includes a flange portion extending annularly outwardly for engaging a return spring. A piston guide includes a tubular portion guiding the piston rod and a shoulder for engaging the return spring. A throat of the piston guide holds a gland seal surrounding the piston rod. An outlet valve housing includes a tubular protrusion extending into the throat of the piston guide to hold the gland seal.

According to at least one embodiment, the present disclosure provides a pump system for a brake system, comprising: an oil reservoir; a pump housing having a suction port and a discharge port formed therein; a motor disposed at a side of the pump housing; an electronic control unit disposed at another side of the pump housing; a pump installed in the pump housing and having a suction channel, which is connected with the suction port, and a discharge port, which is connected with the discharge port, therein; a shaft coupled to the motor to rotate and having a rotating body configured to operate the pump; and a pump-reservoir pipeline configured to connect the suction channel to the oil reservoir.

A towable crash-attenuating vehicle is shown having a frame; at least two axles coupled to the frame, each of the axles having wheels attached thereto; a T-shaped ballast coupled to the frame, and oriented such that the weight of the ballast is biased toward the front end of the frame; deflection shields coupled to the right and left sides of the frame, wherein the deflection shields cover the frame and a majority of the wheels on each side of the vehicle; a tow connection coupled to the front of the frame, pivotable from a deployed state to an undeployed state; an impact attenuator coupled to the rear of the frame; wherein the vehicle is provided with a brake system, and wherein said brake system may be locked and unlocked and wherein the vehicle is provided with an on-board mechanism for locking and unlocking the brake system.

A gasket device for a pneumatic valve system, in particular of a commercial vehicle, comprises gasket part being adapted to be inserted into at least a groove of a contact face of a first casing part, e.g. an adapter, the gasket part comprising at least one gasket chamber for sealingly connecting device channels of mounted casing parts; a body part being adapted to be received in a valve seat of the casing part; at least one spring part connecting the body part and the gasket part,
wherein the body part is moveable in an airflow direction relative to the gasket part by bending or stretching the at least one spring part,
wherein in an unbiased basic condition of the gasket device the body part is positioned above a gasket plane defined by the gasket chamber.

The gasket device is made as a single part of a flexible, elastic material.

The present invention relates to a braking arrangement for a vehicle, the braking arrangement comprising an electric machine electrically connectable to an electric power source, a brake compressor positioned in an air flow conduit, the brake compressor being configured to pressurize a flow of air and to exhaust the pressurized flow of air, and a compressor shaft mechanically connecting the electric machine and the brake compressor to each other, wherein the electric machine is configured to generate a torque on the compressor shaft for operating the brake compressor to pressurize the flow of air, the braking arrangement further comprising an air bearing arrangement, the air bearing arrangement being fluidly connectable to a pressurized brake air tank of the vehicle via an air bearing conduit, wherein the air bearing arrangement is suspending the compressor shaft to at least one of the electric machine and the brake compressor.

An electro-hydraulic brake system includes a master cylinder (MC) fluidly coupled to an MC fluid passageway and configured to supply fluid into the MC fluid passageway in response to pressing force on a brake pedal. A pressure supply unit (PSU) includes an electric motor and a PSU piston disposed within a piston bore, the PSU piston is movable through the piston bore by the electric motor and divides the piston bore into a first chamber and a second chamber. A pedal feel emulator (PFE) includes a PFE piston movable through a PFE bore and separating an upper chamber from a lower chamber. Fluid is conveyed from the lower chamber of the PFE to the second chamber of the PSU in response to a compression of the PFE. The MC fluid passageway provides a fluid path from the master cylinder into the upper chamber of the PFE.
