[0004] Aiming at the problems in the prior art of the air pressure braking technology device that the emergency brake is lightly stepped and the brake is not effective when the heavy step is applied, the present invention provides a cylindrical cone type relay pump valve device for automobiles and its braking method and application. The high-pressure gas pushes the cylindrical cone and then pushes the brake moving groove and the brake roller to achieve the purpose of valve opening, so that the high-pressure gas enters the inner cavity of the relay valve, and the high-pressure gas generated by the relay valve is delivered to each brake through the brake air channel. Slave cylinder to achieve good braking effect

Abstract
The invention discloses an automobile cylindrical cone type relay pump valve device and a braking method and application thereof, and belongs to the technical field of automobile braking. The relay pump valve device comprises a relay valve top cover, a master pump air inlet and outlet channel I, a brake piston, a brake piston return spring, a cylindrical cone, an air inlet channel, an air inlet channel pressure spring, an air inlet channel pressure valve body, an air inlet channel rubber sealing gasket, an exhaust channel, a brake air channel, a shell square hole, a brake moving groove, a brake roller, a relay valve shell, a brake air chamber and the like. According to the device, the cylindrical cone is arranged below the brake piston, the brake piston drives the cylindrical cone to move downwards under the action of high-pressure air flow, a brake roller or a brake moving steel ball can be quickly and accurately pushed, a contact interface is gradually changed, braking is flexible, and the effects of light treading deceleration and heavy treading emergency braking can be effectively achieved; therefore, the problems that in the prior art, due to the fact that a relay valve is inflexible in braking, emergency braking is caused by light treading, and braking is inflexible due to heavy treading are effectively solved, and the rapid and accurate speed reduction or braking effect is achieved.
Description
technical field [0001] The invention belongs to the technical field of automobile braking, and in particular relates to a cylindrical-cone relay pump valve for an automobile braking system, and a braking method and application of the relay pump valve. Background technique [0002] When the car is running or parking, it needs a good braking system to slow down or stop in time to ensure the safety of the car. At present, there are two kinds of braking systems used in automobiles: one is hydraulic braking technology device, and the other is pneumatic braking technology device. Among them, the pneumatic brake technology device is mainly composed of an air pump, an air storage tank, a master cylinder, a relay valve and a sub-pump. Its main working process is as follows: the air pump (also called air compressor) is driven by the engine, compresses the air into high-pressure gas, and stores it in more than two air storage tanks. The pumps are connected; the other air storage tank...
