Abstract
The utility model discloses a three-axle synchronous relay valve, which is capable of synchronizing no-load three-axle braking and guaranteeing long service lives of tires. The three-axle synchronous relay valve comprises a valve body, a piston arranged in the valve body, and gas outlets arranged on two sides of the valve body and connected with a front axle cavity. A cavity of each gas outlet connected with the front axle cavity is provided with a throttle valve inside. The three-axle synchronous relay valve is applicable to braking of three-axle semitrailers.
Description
Technical field
The utility model relates to a kind of motor vehicle braking system, relates in particular to a kind of synchronous relay valve that is used on the three bridge superimposed trailer motor vehicle braking systems.
Background technology
At present, the common emergency relay valve of using on three bridge superimposed trailer vehicles comprises valve body, valve body one side is provided with and admission port, the air supply opening that is connected with air receiver, the air extractor duct that links to each other with brake system controlling control mouth that source of the gas is connected, be connected with the air feed source of the gas and the exhausr port that communicates with the external world, and the piston in the valve body, the valve seat below the piston and valve etc., its radical function is: realize service braking, air receiver is put on the air, realizes emergency braking etc.Three bridge stands under load are consistent as far as possible before, during and after when making heavy duty, the low diff-H design in high back before homemade three bridge superimposed trailer vehicle bridge adopt, thereby vehicle is when zero load, propons with in, back axle is stressed different, propons is lighter, in, back axle is heavier, the brake of three bridges can't realize synchronously when causing zero load, thereby the propons phenomenons such as tire is serious of dawdling take place, directly influence tire service life and traffic safety.
The utility model content
The technical problems to be solved in the utility model provide a kind of unloaded three bridges brake synchronously, the synchronous relay valve of three bridges of tire long service life.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises valve body, be located at piston in the valve body, be located at the air extractor duct that the valve body both sides are connected with the propons chamber, is provided with flow regulating valve in described and the air extractor duct cavity that the propons chamber is connected.
Owing to be provided with flow regulating valve in the utility model with in the air extractor duct cavity that the propons chamber is connected, when unloaded glancing impact, during the air-flow of this air extractor duct lags behind, back axle bonded assembly air extractor duct, thereby play the effect of slowing down braking, and when unloaded propons with respect in, back axle stressed less, bridge is realized synchronous braking before, during and after in the time of can making zero load, thereby avoids the dawdle generation of tire phenomenon of propons, improves tire service life.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail:
As shown in drawings: the utility model comprises valve body 1, be located at piston 2 in the valve body 1, be located at the air extractor duct that is connected with the propons chamber 3,5 of valve body 1 both sides, is respectively equipped with flow regulating valve 6,7 in air extractor duct 3,5 cavitys that are connected with the propons chamber.
During the utility model work, piston 2 moves down, gas is discharged to air extractor duct 3,5,8,9 respectively in valve body chamber 10, because the effect of flow regulating valve 6,7, the exhaust velocity of air extractor duct 3,5 wants slow with respect to the exhaust velocity of air extractor duct 8,9, and air extractor duct 3,5 is connected with the propons chamber, air extractor duct 8,9 with in, the back axle chamber is connected, thereby it is more slow relatively to act on the propons retro-speed, and the propons relevant position is stressed lighter when zero load, thus bridge synchronous braking before, during and after realizing when making zero load.
Claims (1)
1. synchronous relay valve of bridge comprises valve body, is located at piston in the valve body, is located at valve body both sides and the air extractor duct that the propons chamber is connected, and it is characterized in that being provided with flow regulating valve in described and the air extractor duct cavity that the propons chamber is connected.
