Abstract
The utility model relates to a relay valve for a vehicle, which belongs to the technical field of vehicle braking component. The relay valve comprises a relay valve body, a relay valve cover, a piston, a fixing seat and an air inlet valve sliding bar, wherein the piston is installed in the relay valve cover, and an exhaust valve is installed below the piston; the fixing seat and the air inlet valve sliding bar are installed in the relay valve body, and an air inlet valve is installed on the air inlet valve sliding bar; a control port is arranged on the relay valve cover; an air inlet and an air outlet are arranged on the relay valve body, and an exhaust port is arranged at the lower end of the fixing seat. The control port and the piston are adopted to control the air pressure at the air inlet and the air outlet to form difference between controlled air pressure and output air pressure, thereby avoiding the problems that the vehicle starts up slowly, the sensitivity is poor and the driving safety of the driver is affected due to the structural reason of the prior relay valve; the vehicle braking can be more rapid and reliable, the braking can be released rapidly, the vehicle can starts up quickly, and better safe driving effect is brought to the vehicle users.
Description
Technical field:
The utility model relates to a kind of Car Relay Valve, belongs to automobile brake component technology field.
Background technology:
Car Relay Valve is to be used for shortening the brake response time of handling in the gas circuit, plays a part to quicken and put soon.At present, the heavy position relay valve that truck adopted in China's auto trade, because its structural reason makes vehicle start slow, sensitieness is poor, the braking releasing time is long, influences the traffic safety of the drive behavior and the automobile of chaufeur.
Summary of the invention:
The purpose of this utility model is: a kind of good reliability is provided, and highly sensitive, the braking releasing time is short, can improve the Car Relay Valve of whole brake system of car response time.
The utility model is to realize above-mentioned purpose by following technical solution:
A kind of Car Relay Valve, it is made of relay valve valve body, relay valve valve gap, piston, permanent seat, air inlet valve sliding bar, it is characterized in that: in the relay valve valve gap piston is housed, drain tap is housed below the piston; Permanent seat and air inlet valve sliding bar are housed in the relay valve valve body, between permanent seat and the air inlet valve sliding bar spring are housed, on the air inlet valve sliding bar air intake valve is housed; Be shaped on a boss on the outside face of relay valve valve gap, boss is provided with the control mouth; The relay valve valve body is provided with an admission port and three delivery ports, and admission port and three delivery ports are mutually 90 ° of rectangular distributions, and the permanent seat lower end is provided with exhausr port, and the relay valve valve gap is installed on the relay valve valve body through bolt.
The utility model beneficial effect compared with prior art is:
The utility model adopts control mouth and piston that the air pressure of admission port and delivery port is controlled, form the difference of control air pressure and output pressure, thereby avoided existing Car Relay Valve because the vehicle start that reasons in structure caused is slow, sensitieness is poor, influence the problem that driver safety is driven, realize making automobile brake failure-free purpose more rapidly, brought safe driving effect better for vast user vehicle.
Description of drawings:
Fig. 1 is the contour structures scheme drawing of Car Relay Valve;
Fig. 2 is the sectional structure scheme drawing of Car Relay Valve.
Among the figure: 1, boss, 2, drain tap, 3, control mouthful, 4, piston, 5, the relay valve valve gap, 6, air intake valve, 7, bolt, 8, the relay valve valve body, 9, admission port, 10, exhausr port, 11, delivery port, 12, permanent seat, 13, the air inlet valve sliding bar, 14, spring.
The specific embodiment:
This Car Relay Valve is made of relay valve valve body 8, relay valve valve gap 5, piston 4, permanent seat 12, air inlet valve sliding bar 13.Piston 4 is housed in the relay valve valve gap 5, and piston 4 constitutes an annular seal space with relay valve valve gap 5 inside faces, drain tap 2 is housed below the piston 4.Permanent seat 12 and air inlet valve sliding bar 13 are housed in the relay valve valve body 8, between permanent seat 12 and the air inlet valve sliding bar 13 spring 14 are housed, air intake valve 6 is housed on the air inlet valve sliding bar 13.Be shaped on a boss 1 on the outside face of relay valve valve gap 5, boss 1 is provided with control mouthfuls 3, and control mouthfuls 3 is connected with annular seal space.Relay valve valve body 8 is provided with an admission port 9 and three delivery ports 11, and admission port 9 and three delivery ports 11 are mutually 90 ° of rectangular distributions, and permanent seat 12 lower ends are provided with exhausr port 10, and relay valve valve gap 5 is installed on the relay valve valve body 8 through bolt.
The utility model working process is, the pressurized air of coming from source of the gas enters from admission port 9, and this moment, air intake valve 6 was in closed condition, and drain tap 2 is in opening.When automobile brake, the pressurized air that brake activation valve transports enters from control mouth 3, acts on piston 4 tops, produces downward application force, and piston 4 moves downward, and closes drain tap 2, opens air intake valve 6, and delivery port 11 has air pressure to transfer to brake cylinder; When reaching balance, air intake valve 6 and drain tap 2 are closed simultaneously, realize automobile brake failure-free purpose more rapidly.When brake off, piston 4 upper pressure are zero, piston 4 upward movements, and air intake valve 6 is closed, and drain tap 2 is opened, and the air pressure of delivery port 11 is then discharged rapidly from exhausr port 10, and brake off is rapid, makes vehicle start very fast.
