Abstract
The utility model discloses a relay valve assembly for an automobile, which comprises a lower valve body and an upper valve body which is arranged on the lower valve body, wherein a control opening, a service opening and an exhaust opening are arranged on the upper valve body; a valve assembly is arranged in the upper valve body, and a vent pipeline I is also arranged on the upper valve body and is communicated with a vent pipeline II which is arranged on an air inlet of the lower valve body. The utility model causes the braking reaction time and the braking release time to be shortened, the operation is flexible and convenient, and any hysteresis effect can not be generated. The utility model is suitable for various middle heavy type trucks and passenger cars.
Description
Technical field
The utility model relates to a kind of Car Relay Valve assembly.
Background technology
The kind of automobile is a lot, and the vehicle wheel base that has is longer, and its brake piping is also longer relatively, and the air pressure in the pneumatic process lags behind, and has had a strong impact on traffic safety.Standard GB 12676 regulations, from October in 2003 M3 class on the 1st motorcoach, N2 class load-carrying vehicle and O4 class trailer must install and meet a class anti-skid brake system (ABS) and an automatic clearance adjuster of stipulating among the GB13594, but facts have proved, air brakes vehicles for long wheelbase, even ABS anti-skid brake system and automatic clearance adjuster have been installed, still can not solve the traffic safety problem preferably, for the long wheelbase vehicle of running at high speed, the reaction time hysteresis problem of compression air brake remains subject matter.
Summary of the invention
The purpose of this utility model is to provide a kind of flexible operation, the Car Relay Valve assembly that brake response time is short.
To achieve these goals, the technical solution adopted in the utility model is, described Car Relay Valve assembly comprises valve body and the upper valve body that is installed in down on the valve body down, upper valve body is provided with a control mouth, a service port and an exhausr port, it is characterized in that: be provided with valve assembly in upper valve body inside, also be provided with vent line I on the upper valve body, and communicate with vent line II on being located at down the valve body admission port.
Described valve assembly comprises the base of being with O-ring seals, be located at fixed cover, big piston, an end on the base is through valve piston in the big piston, is located at the valve seat on the exhausr port and is located at two way valve on the valve seat, also be provided with back-up ring on the described base, the described valve piston end that is through in the big piston is provided with spring perch, between spring perch and fixed cover, be provided with pull back spring, be provided with pull back spring between described valve piston and two way valve.
As a kind of optimal way of the present utility model, described vent line I is 7 fonts.
The utility model compared with prior art has following obvious advantage and progress: (1) the utility model has shortened brake response time and has removed braking time; (2) the utility model flexible and convenient operation does not have any gantry hysteresis.The utility model is applicable to all kinds of medium and heavy lorries and passenger vehicle.
Description of drawings
Fig. 1 is an integral structure cut-away view of the present utility model.
