Embodiment
[0048] Example: see figure 1 , 3 , Figure 5-8 , A secondary point brake master valve, including an upper valve body and a lower valve body connected together by bolts,
[0049] The upper half of the upper valve body shell is provided with a stepped balance piston chamber,
[0050] In the balance piston chamber, there is a two-stage point brake balance piston assembly, including a balance piston body, a spring pack, and a mandrel seat. The upper part of the balance piston body is a cylindrical web chamber, and the lower part of the balance piston body The protruding cavity-shaped protrusion is the rod chamber; the upper part of the ejector rod seat is the frame plate, and the lower part is the three-stage stepped rod body extending from the frame plate, which is successively tapered. The rod body, the second rod body, the third rod body, and the lower section of the third rod body are inserted into the rod chamber at the lower part of the balance piston body, and the web is instal...

Abstract
A two-stage and three-stage point brake master valve, the spring package of the internal two-stage point brake balance piston and the three-stage point brake balance pistonassembly adopts the upper ring-shaped inner flanging and the lower ring-shaped outer flanging The structure simplifies the structure of the spring clasp, reduces the difficulty of processing and assembly, and can greatly improve the pass rate of the product. The spring pack can be formed directly by cutting, or it can be formed once by stamping process. The processing process is simple, and the spring installation inside the spring pack is also much simpler.
Description
Technical field [0001] The invention mainly relates to the technical field of parts and components of automobile brake valves, in particular to a secondary and tertiary point brake master valve. Background technique [0002] The brake system of trucks and heavy vehicles in the prior art brakes too quickly, and the foot feel is not well controlled. It is easy to cause the brake pads to heat up rapidly and cause carbonization, which directly affects the braking effect. The deviation affects the overall stability, resulting in insecurity or unnecessary economic losses. In order to solve these braking problems of trucks, our unit has successively proposed patents for the two-stage spot brake master valve and the three-stage balanced pistonassembly, which can output “two or three-stage spot brakes”. The principle of "spot brake" enables compressed air to form pulses in the control pipes and air chambers, which act on the brake pads, and each pulse is equivalent to rubbing the brake ...
