Provided is a support structure for a plurality of electrically actuated brake fluid pressure generation devices provided in a vehicle in which automated driving is enabled, the brake fluid pressure generation devices being configured to generate brake fluid pressure. The support structure includes a support member (a first bracket, a second bracket, and an actuator bracket) via which a brake actuator and a brake unit are supported by frame members forming a storage chamber separated from a vehicle cabin. The support member is supported by the frame members at two points. The brake actuator and the brake unit are mechanically connected to each other via the support member.

A spring brake chamber for pneumatic braking systems used in heavy commercial vehicles such as buses, trucks, trailers and tractors, includes a power spring configured to detect the parking position, the driving position and the situation in which the power spring is broken. The present invention allows the driver to be notified by sending a signal.

Disclosed is a rail braking system including a detection and storage device designed to receive first information representing the position of a device for locking a service brake piston, to receive second information representing the supply of a service brake pressure chamber with a pneumatic pressure agent, to deduce information representing the application of a parking brake from the first and second information, and to store the deduced information; as a result of which the information representing the application of the parking brake is kept even if the service brake pressure chamber is no longer supplied with the pneumatic pressure agent.

A suspension assembly for a heavy-duty vehicle axle/suspension system that includes a geometry that enables components of a brake system to be mounted above and be protected by a beam of the suspension assembly. In an embodiment of the suspension assembly, the beam includes a recessed area that allows a brake actuator to be positioned at least partially within or disposed adjacent the recessed area.

Self-steering axle assembly has an axle with central tube having a longitudinal central axis. A king pin is connected with an end portion of the axle. A knuckle is connected with the king pin. The knuckle includes a torque plate section. A first arm of the knuckle extends from a side of the torque plate section and receives a first end portion of the king pin. A second arm extends from the torque plate section in the same direction as the first arm. The second arm receives a second end portion of the king pin. A spindle is friction welded to the torque plate section and has a longitudinal central axis. The torque plate section has at least one surface on the torque plate section extending substantially perpendicular to the longitudinal central axis of the spindle. A tool engages the surface during friction welding of the spindle to the torque plate section. The relative locations of the axle, spindle and king pin enable an air disc brake actuator to avoid contact with components of the heavy-duty vehicle during steering and with the ground and debris.

An emergency braking device including an actuator (2), a pressurizing circuit (3) supplying the actuator (2) via a control pressure and a discharge circuit (4). The discharge circuit (4) includes restrictors (13, 14) for controlling the pressure and/or flow rate of the supply fluid of the actuator (2) during a discharge of the actuator. The restrictors (13, 14) are configured to define an intermediate pressure between a low pressure level and the control pressure of the actuator (2).

A powered vehicle includes a spring-applied hydraulic release (SAHR) vehicle brake comprising first and second mutually engageable brake elements. The first brake element is secured to or forms part of a rotatable element of the drive train of the vehicle and the second is non-rotatably moveably mounted on the vehicle such that the first and second elements are mutually engageable with and separable from one another. Mutual engagement of the brake elements causes braking of rotation of the rotatable element. The SAHR vehicle brake includes (i) a resiliently deformable member acting on the second brake element so as to urge the first and second brake elements into mutual engagement and (ii) a hydraulic control circuit for applying hydraulic pressure to the second brake element so as to oppose the action of the resiliently deformable member and thereby normally maintain the first and second brake elements separated from one another.

A rubber molded product such as a brake cylinder diaphragm with a balanced elongation substrate reinforcement in both the warp and fill directions incorporated therein is provided. The fabric substrate reinforcement is woven without size and overfed after the weaving process leading to balanced crimp and elongation in the length and width directions. The fabric member is also woven with a reduced number of weft threads to start, but which are added back by overfeeding to further render the fabric elongation more isotropic in at least the warp and fill directions. The reinforcement substrate is placed in the mold along with the molding material and formed into the desired shape to assist in shape retention and overall structural stability. A method of forming a molded product including a balanced crimp reinforcement substrate is also provided.
