Embodiment 1

[0022] Embodiment one: see figure 1 , figure 2 , image 3 and Figure 5 , in the figure, 1-upper piston sleeve, 2-dust cover, 3-pump cover, 4-rod, 5-rod seat, 6-pressure stabilizing rubber pad, 7-pedal mounting seat, 8-rod seat Circlip, 9-upper piston, 10-upper pump body, 11-upper valve, 12-rear brake air intake, 13-middle pump body, 14-lower piston sleeve, 15-lower pump body, 16-front system Dynamic intake hole, 17-lower valve, 18-lower valve plug, 19-dust pad, 20-seat ring, 21-lower valve plug retainer, 22-front brake air outlet, 23-lower piston , 24-upper valve plug snap ring, 25-rear brake air outlet, 26-upper valve plug, 27-air vent, 28-pressurized air intake.

[0023] The single-input and multiple-outlet two-stage electromagnetic booster brake master cylinder includes a pump cover 3, an upper pump body 10, a middle pump body 13 and a lower pump body 15, which are fixedly connected by bolts in sequence, wherein the pump cover 3 and the upper pump body 10 The center ...

Embodiment 2

[0030] Embodiment two: see Figure 4 , the numbers in the figure are the same as those in Embodiment 1. The meanings are the same, and the similarities will not be repeated. The difference is that the middle pump body 29 is a combination of the upper pump body and the middle pump body in Embodiment 1, and the lower pump body 31. The specific structure of the lower piston 33, the lower piston sleeve 30, the lower valve plug 32, the dust-proof pad 34, and the lower piston 36 is different from the corresponding parts in the first embodiment, and the lower valve plug 32 is fixed on the lower pump with the lower end cover 33 Body 31, and dust-proof pad 34 is fixed on the lower end cover by rivet 35, the structure is different, but the working principle is the same. This embodiment is suitable for Qingdao Jiefang series air brake type.

Abstract

A single-in multi-out two-stage electromagnetic boosted braking pump is composed of the pump cove and upper pump body with upper piston module, a middle pump body with upper valve and lower 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 single-inlet and multiple-outlet 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 follows is a substantial increase in traffic accidents, causing huge physical injuries and economic losses, and one of the main reasons for traffic accidents is the inappropriate braking effect of vehicles. 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...
