A hydraulic block of an electronic braking device for vehicles, includes: a first input port for receiving brake oil from a master cylinder; a first output port for discharging the brake oil to a wheel brake; a first inlet valve port for accommodating a first inlet valve disposed on a first inlet flow path connecting the first input port to the first output port; and a first outlet valve port for accommodating a first outlet valve disposed on a first outlet flow path configured to depressurize the brake oil. The first outlet flow path is configured to pressurize the first outlet valve in an axial direction of a first plunger mounted inside the first outlet valve and to deliver the brake oil to the first outlet valve.

A master cylinder for a brake. The master cylinder includes a cylinder main body having a hydraulic pressure chamber, a reservoir tank having a storage chamber, and a separator that is provided in the reservoir tank to divide a space in the storage chamber of the reservoir tank into an upper region and a lower region. A hydraulic fluid is storable in the hydraulic pressure chamber, and is storable in the storage chamber for thereby replenishing the hydraulic pressure chamber. The hydraulic fluid is circulatable between the upper region and the lower region, such that a liquid surface of the hydraulic fluid is in the upper region. The separator has a lower surface in the lower region. The lower surface has an inner portion, and an inclined portion that surrounds the inner portion and that is inclined outwardly and upwardly with respect to the inner portion.

A brake system damping device includes a first space, a second space, a third space, a first separating element, a second separating element, a closure element, and a plug-type element. The first space is configured to have hydraulic pressure applied thereto. A compressible medium is situated in the second space and the third space. The first separating element separates the first space from the second space, and the second separating element separates the second space from the third space. The second space is connected in medium-conducting fashion to the third space by a passage formed in the second separating element. The closure element is configured to be moved with the first separating element so as to close the passage in a movement direction as soon as the hydraulic pressure has reached a predefined pressure value in the first space. The plug-type element is arranged in the passage.

A vehicle braking system includes a service brake and/or a parking brake, a network of pneumatic pipes provided for supplying, via at least one pneumatic pressure agent, the service brake and/or the parking brake to place the brake(s) in an engaged state or a disengaged state, and a display device for displaying the engaged state and/or the disengaged state of the service brake and/or of the parking brake. The display device includes at least one pneumatic intake connected to the service brake and/or to the parking brake via the network of pneumatic pipes, at least one electrical input, at least one electro-pneumatic triggering member connected to the pneumatic intake and to the electrical input, and at least one electronic display member connected to the electro-pneumatic triggering member and controlled to display the engaged state or the disengaged state of the service brake and/or of the parking brake.

A brake release system for a vehicle is described to transfer mechanical movement between two hydraulic actuators. The system includes a first hydraulic system on a removable portion of the vehicle and a second hydraulic system on a main chassis of the vehicle. The two hydraulic systems are mechanically engaged with each other where the removable portion of the vehicle attaches to the main chassis. In this way, a force applied to the removable portion of the vehicle when the vehicle's tow hook is engaged may be transferred to release the parking brake on the main chassis without a hydraulic connection between the removable portion and the main chassis. This may be useful when a removable battery frame with a tow hook makes up a separable rear portion of an electric vehicle, allowing the battery frame to be quickly and efficiently removed from the main chassis of the vehicle.

A gladhand assembly includes a gladhand that rotates about a first axis with respect to a sealed housing. The sealed housing includes a lever affixed to the first axis to rotate as the gladhand rotates. A stop within the sealed housing may be configured into an engaged position in which it engages with the lever to lock the gladhand into a fixed position in which the gladhand cannot be rotated about the first axis. In addition, the stop may be configured into a retracted position to permit the lever to rotate and allow the gladhand to be rotated into a deployed position.

Air brake tubing is provided having an air brake tube body comprising at least one layer formed from a composition comprising a copolyester, polyethylene terephthalate or polybutylene terephthalate; and a thermoplastic polyurethane.
