(Fig 1) A vehicle braking system 10 for use in a vehicle having a tractor and a trailer including: a control unit 50, a supply line 12 for connecting to a source of pressurised fluid, a control line 30 for connecting to a source of pressurised fluid on demand, an auxiliary fluid reservoir 28, a…
Systems and methods allow for controlling brakes of a trailer coupled to a tractor. The systems and methods utilize an inversion valve input between an emergency brake controller and a trailer connection at the tractor. The inversion valve receives a supply air from an output of the emergency brake…
A system for electrically controlling air brakes on a trailer having an electrically actuated valve for releasing pressurized air at a controlled rate. The trailer is connectable to a standard electrical connector on a towing vehicle that provides a proportional braking signal. The proportional…
The valve device has a trailer brake valve for brake assembly and a trailer associated valve such as level control valve or lifting axle valve for an air suspension system. The trailer associated valve of air suspension system is integrated into device main housing. An electronic control unit (72)…
The device (5) has an emergency brake valve (19) controlling pressurization of a service brake based on pressure at a terminal (21) that is connected with a coupling head (2). A spring accumulator valve controls the pressurization of a spring brake based on pressure at another terminal (45) that is…
The compressed air system (1) has an emergency brake valve (19) which is applied with a pressure of a container (4) depending on the pressure at a terminal (141). The terminal is connected with a coupling head (2). A shuttle valve is provided with an input which is connected with another terminal…
The assembly (7) e.g. modular valve unit (9), has a supply port (15) and a spring-loaded port (28), where an emergency braking- and/or uncoupling function is integrated in the assembly and causes automatic aeration of the spring-loaded port when the supply port is not under pressure. A valve body…
The parking valve (14) has an output terminal (34) for compressed air pressurization of a spring-loaded parking brake (16). A supply port (35) is connected to an output terminal in a ventilation position. A pressure safety valve (31) is interposed in the ventilation position between the supply port…
An inlet connection (24) works with a reserve pipe (20) and a connection (26) for a reservoir (28). A first outlet connection (OC) (37) operates brake control pressure for a service brake cylinder (46). A second OC (54) operates a release pipe that leads to spring brake cylinders. An emergency…
The combivalve (1) has a housing (2) containing an emergency braking piston (3) acted on by a spring (20) and incorporating a spring-loaded double valve element (14), cooperating with an inlet valve seat (17) and an outlet valve seat (30), an operating device for the combination valve providing…
When the brake pedal is depressed a pressure sensor (20) indicates the pressure required to apply the brakes (6) and the electric control system (23) adjusts a valve system (26,27,29) accordingly to admit air to the brake cylinder. Should the control unit fail an emergency brake device (14)…
