Abstract

The invention discloses an ABS urgent relay valve, which consists of electromagnetic adjusting valve and relay valve, wherein the relay valve is fixed on the bottom of electromagnetic adjusting valve with inlet of master cylinder connecting inlet pipe through electromagnetic valve, which controls cavity C, the vent top of relay valve connects depression channel through electromagnetic adjusting valve, the relay valve adopts urgent relay valve with vent pipe in the center of urgent relay valve, when the gas supplying pipe is broken suddenly, the vehicle breaks gas to brake urgently, which improves safety of entire vehicle.

Description

Technical field [0001] The invention provides an ABS emergency relay valve, which belongs to the technical field of automobile braking. Background technique [0002] As my country's expressway backbone network has been basically formed, large-tonnage, long-wheelbase semi-trailers and trailers with obvious cost advantages per ton-kilometer are also increasing year by year. When a long-wheelbase vehicle brakes in an emergency, the wheels are locked and slipping, resulting in extended braking distances, vehicle deviation or sideslip, and loss of steering ability, especially in bad weather, poor road conditions, and high-speed driving prone to traffic accidents. Contents of the invention [0003] The object of the present invention is to provide an ABS emergency relay valve which can overcome the above defects, can be installed on a semi-trailer or a trailer, has an emergency braking function, and has excellent working performance. Its technical content is: [0004] Includi...
