MULTIFUNCTIONAL TRAILER BRAKE VALVE Russian patent published in 2024 - IPC B60T7/20 B60T13/68 B60T13/26 B60T15/22 

FIELD: automotive technology.

SUBSTANCE: multifunction trailer brake valve. The multifunctional trailer brake valve consists of a housing (1) in which a piston (2) is installed, spring-loaded from above by a spring (3); cavity A, which communicates with the power line from the tractor (4); cavity B, which communicates with the signal line from the tractor (9); cavity C, which communicates through the channel (10) in the wall of the body with the brake chambers (11) of the trailer; cavity D, in which the solenoid rod (12) is installed, which rises up into the piston (7) until it is stopped by the spring (13), winding (14), which can be connected to the battery (15) through a normally open contactor (16) with a piston (17) spring-loaded from below, while an anti-winding (18) is installed around the solenoid rod (12), which is connected to a microgenerator (19), which, together with the speedometer cable (20), has a common drive from the worm gear (21) on the output shaft gearboxes (22), moreover, the anti-winding (18) allows opening the winding (14) of the inlet valve-piston (31) to the extent that the braking force of the trailer or semi-trailer corresponds to the braking force of the tractor in all types and modes of braking.

EFFECT: ensuring trailer or semi-trailer braking for all types and modes of braking.
