Embodiment 1

[0025] Embodiment one: see figure 1 , figure 2 , image 3 and Figure 7 , in the figure, 1-upper pump body, 2-retaining spring of ejector seat, 3-dust cover, 4-rubber pad for stabilizing pressure, 5- ejector seat, 6-retaining spring of dust cover, 7-upper piston sleeve , 8-upper valve, 9-rear brake air intake, 10-upper valve plug, 11-upper valve plug retainer, 12-lower piston sleeve, 13-front brake air intake, 14-lower pump Body, 15-lower valve plug circlip, 16-lower valve plug, 17-lower valve plug positioning seat, 18-front brake air outlet, 19-lower valve, 20-lower piston, 21-rear brake Vent, 22-boost air intake, 23-upper piston.

[0026] The three-inlet and multiple-outlet two-stage electromagnetic booster brake master cylinder includes an upper pump body 1 and a lower pump body 14, which are fixedly connected by bolts, and the upper pump body 1 is provided with a push rod seat 5 and a pressure-stabilizing rubber pad 4 , the upper piston 23, the upper return spring, t...

Embodiment 2

[0033] Embodiment two: see Figure 4 , Figure 5 , Figure 6 and Figure 7 , the number in the figure is the same as that of Embodiment 1. The meanings are the same, and the similarities will not be repeated. The difference is: the upper pump body 1, the lower pump body 14, the lower piston 20, the lower piston sleeve 12, and the dust cover 3 The specific structure is different from the corresponding parts in the first embodiment, and the dust cover 3 is provided with a gland 25, although the structures of the corresponding parts are different, but the working principle is the same. This embodiment is suitable for Cummins series air brake type.

Abstract

A three-in multi-out two-stage electromagnetic boosted braking pump is composed of an upper pump body with upper piston, upper valve and low piston modules, a lower pump body with lower valve module, an upper piston sleeve, and a two-position three-way electromagnetic valve.

Description

1. Technical field: [0001] The invention relates to an automobile brake pump, in particular to a three-inlet and multi-outlet type two-stage electromagnetic booster brake master cylinder. 2. Background technology: [0002] With the rapid development of the economy, more and more people and goods are appearing in various parts of our country. As one of the important means of transportation and transportation, automobiles are becoming more and more popular in families and businesses. But what followed was a sharp increase in traffic accidents, causing huge physical injuries and economic losses, and one of the reasons for traffic accidents is that the braking effect of vehicles is not suitable. The existing vehicle brake master cylinder drives a tappet down through the vehicle brake pedal to push the upper piston down, first opens the rear wheel brake valve to brake the rear wheel; then the upper piston contacts with the upper end of the lower piston, pushing The lower piston ...
