Abstract

The utility model discloses an automobile brake variable-pressure regulation and control device, which comprises an upper cover, a casing body, a piston and membranes. The upper end of the casing body is screwed with the upper cover; the upper cover and the casing body are respectively provided with an air inlet hole communicated with an upper chamber; an upper membrane, a gasket and the piston are arranged inside the upper chamber; a linkage rod is screwed with the upper membrane and the piston which are arranged inside the upper chamber; a lower membrane and a gasket are arranged inside a lower chamber; the lower end of the linkage rod is screwed with the lower membrane arranged inside the lower chamber; the tail end of the linkage rod matches with an air inlet valve and an air exhaust valve; and the lower end of the casing body is connected with an emergency relay valve, relay valves, trailer valves or brake master cylinders. The regulation and control device is connected with various trailer valves, the relay valves or the brake master cylinders through the lower end of the casing body, thereby regulating braking force of an empty automobile or a loaded automobile. As the piston for reducing pressure is arranged below the lower membrane inside the upper chamber of the casing body, the regulation and control device is capable of preventing poor braking after the upper membrane is damaged. The device enables air pressure entering a braking chamber to be divided into pressurization first stage and depressurization second stage, balances braking and facilitates operation of drivers. By arranging the upper membrane and the lower membrane, the device decreases friction resistance of the piston, and enables the piston to return easily and work flexibly.

Summary of the invention
The purpose of this utility model is to provide a kind of braking automobile transformation regulation device, can be under the different condition of load-carrying according to main drive axle, trailer axle, supply with the rational different pressures pressurized air in drag chamber, thereby play the effect of each bridge synchronous braking, unloaded effect of easing stress is good, and the heavy duty braking is strong.
The technical solution of the utility model is: braking automobile transformation regulation device, comprise loam cake, housing, piston and diaphragm, the housing upper end is spirally connected with loam cake, the housing two ends are provided with upper and lower chamber, loam cake and housing are respectively equipped with induction opening and are connected with upper chamber, upper diaphragm is set in the upper chamber, the upper diaphragm top is provided with pad, the below is provided with piston, housing one side between corresponding upper diaphragm and the piston is provided with air extractor vent, the diaphragm and the piston bolt that are provided with in trace and the upper chamber, trace is provided with air extractor vent; Bottom chamber is provided with down diaphragm, following diaphragm is provided with pad up and down respectively, the following diaphragm bolt that trace lower end and bottom chamber are provided with, the trace tail end matches with the intake and exhaust valve, and the housing lower end is connected with emergency relay valve, relay valve, trailer valve or master cylinder.
Described emergency relay valve, by lower house, air inlet and exhaust valve, brake piston, retarding spring and gland are formed, lower house and housing bolt, brake piston is arranged in the lower house, and air inlet and exhaust valve is arranged in the brake piston, and the brake piston lower end is provided with orienting sleeve and is located by jump ring.Retarding spring is arranged between piston and the gland, and lower house is provided with several deflation holes, check valve and several induction openings.
The utility model braking automobile transformation regulation device is connected with various trailer valves, relay valve or master cylinder by the housing lower end, thereby adjusts the braking force of empty wagons, loaded vehicle.The piston of decompression usefulness is set below the upper diaphragm of this regulation device in housing upper chamber, can prevent that upper diaphragm from damaging after, cause the poor stop phenomenon.This regulation device makes the air pressure that enters brake repair room be divided into the supercharging one-level, and the decompression one-level makes brake equalization, is difficult for locking, and it is fast to slow down, and reduces wear on tyres, prevents to break away, and chaufeur is easy to operate.The utility model is provided with upper and lower pair of diaphragm, has reduced the frictional resistance of piston, makes the easy return of piston, and work flexibly.
