A circuit has a fluid line matrix and brake components connected to the fluid line matrix. Changes in the brake designs or brake functions can be carried out easily in that at least one interface is provided for connecting a distributor block. The interface is designed such that a configuration of the fluid line matrix can be formed by connecting or exchanging the distributor block. There is also described a distributor block which is suitable for forming a configuration of the fluid line matrix of the circuit by connecting to the at least one interface of the circuit.

A diagnostic method performs a self-diagnosis of an electronically controllable pneumatic braking system for a commercial vehicle. The method includes: receiving a learning signal about the braking system; in response to the reception, putting the braking system into a learning mode and performing the steps: performing a predetermined first activity of the braking system with the commercial vehicle stationary or moving; detecting via a sensor arrangement a first learning system reaction of the braking system in response to the execution of the first activity; and storing the detected first learning system reaction as the first target system reaction in a memory. A braking system and a computer program are also disclosed.

One variation of a system includes a bogie including: a chassis; a first set of latches configured to transiently engage a first subset of engagement features, in a first array of engagement features on a left rail and in a second array of engagement features on a right rail of the trailer, to retain the bogie below a floor of the trailer; a driven axle suspended from the chassis; and a motor coupled to the driven axle and configured to output torque to the driven axle and regeneratively brake the driven axle. The system further includes a battery assembly: including a second set of latches configured to transiently engage a second subset of engagement features, in the first array of engagement features and in the second array of engagement features, to retain the battery assembly adjacent the bogie; and configured to receive electrical energy from the motor.

A braking system may include an enclosed cylinder and a double-sided piston assembly disposed therein. The double-sided piston assembly includes a first piston disposed within the enclosed cylinder, a second piston disposed within the enclosed cylinder, and a linear piston leg connecting the first piston and the second piston. The linear piston leg includes two opposite racks. A segmented pinion is disposed between the two opposite racks, where the segmented pinion includes a cogged segment and a cogless segment. The cogged segment and the cogless segment are on opposite sides of the segmented pinion. A brake shaft is connected to and rotatable with the segmented pinion. A transmission system is configured to couple the brake shaft to a drive shaft of a vehicle. Compressed air or oxygen may be drawn in or discharged from the enclosed cylinder via a one-way inlet valve and a one-way outlet valve.

A compressed-air braking system (DBA*) for a motor vehicle, includes a compressed-air supply device (1) with a compressor (2) and several brake circuits which are connected to the compressed-air supply device (1) via a multi-circuit protection valve (7) and include at least one parking brake circuit with parking brake cylinders (25.1, 25.2). In order to reduce the operating noise of the compressed-air braking system (DBA*) occurring in particular on venting of the parking brake cylinders (25.1, 25.2), it is provided that the parking brake cylinders (25.1, 25.2) can be vented, per wheel or per vehicle axle, alternately either to the surrounding atmosphere or into an additional reservoir (31) via a respective quick-venting valve (29) connected to a connecting line (28) and a changeover valve (30) arranged downstream thereof.
