Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the braking effect of the front wheel or the rear wheel is mutually affected when there is a problem in the braking part of the front wheel or the rear wheel when the existing motor vehicle is braking, and the problem that the front wheel is locked first and the braking force of the rear wheel is insufficient during braking

Embodiment Construction

[0012] The oil outlet passage 11 of the first moving working chamber part of the proportional distribution type brake master cylinder of the present invention is connected with the front wheel brake wheel cylinder of the motor vehicle, and the oil outlet passage 11 of the driven working chamber part is connected with the rear wheel brake cylinder of the motor vehicle. Wheel cylinder connection. When the motor vehicle brakes, the ejector rod pushes the active push rod 4 to move forward, and the main component spring 5 drives the first-moving piston pair 3 to move forward, and the hydraulic oil in the first-moving working chamber is compressed to enter the front wheel brake wheel cylinder. Make the brake friction plate contact with the brake drum or the brake disc, at this moment the main force component spring 5 starts to compress. The active push rod 4 continues to move forward, pushes the driven push rod 6 and the driven piston 8 to move forward, and compresses the hydraulic ...

Abstract

The invention discloses a prorated type brake master cylinder. The middle part of a cylinder body 1 is provided with a clapboard 2 dividing the cylinder 1 into a first-mover operating chamber and a driven operating chamber which are sealed independently; and an active push rod 4 and a driven push rod 6 which are arranged on the first-mover operating chamber respectively pass through a main component force spring 5, a first-mover piston pair 3, an auxiliary component force spring 12, a resetting spring 9 and the clapboard 2 and finally connect a driven piston pair 8 arranged in the driven operating chamber. The prorated type brake master cylinder has simple structure and can replace a proportional valve and a brake master cylinder. When a vehicle with the prorated type brake master cylinder is in braking, under the action of the active push rod 4 and the component force spring 5, first wheels firstly brake rather than lock so as to achieve sufficient front and rear braking forces; under the combined action of the active push rod 4, the driven push rod 6, the main component force spring and the auxiliary component force spring, if one group of brake wheel cylinders or master cylinder packing cups of front wheels or rear wheels is damaged, or when connecting pipes leak oil, the braking effect of the other group can not be influenced.

Description

(1) Technical field [0001] The invention relates to a proportional distribution type brake master cylinder. (2) Technical background [0002] The dual pipeline hydraulic brake master cylinder that present motor vehicle uses is made up of circular cylinder body, piston, leather cup, return spring by the inside. When braking, the first set of piston cups pushes hydraulic oil and the second set of piston cups works. Therefore, when there is oil leakage in one of the brake pipes or the brake wheel cylinder cups of the front or rear wheels, it will affect the braking effect of the other group. At the same time, this type of brake master cylinder (generally, the first set of piston cups is partly connected to the rear wheel brake wheel cylinder, and the second set of piston cups is partly connected to the front wheel brake wheel cylinder), often It is the front wheel brake that locks first and the rear wheel brake is slow and insufficient. (3) Contents of the invention [000...
