Abstract

The invention provides a one-driving-four front-to-back linkage brake pump, belongs to the technical field of machinery, and solves the problems of poor brake effect and unbalanced brake force of the existing brake. The one-driving-four front-to-back linkage brake pump comprises a front brake caliper body, a rear brake caliper body and a linkage pump which is connected with a vehicle pedal plate; the linkage pump is respectively connected with the front brake caliper body and the rear brake caliper body through an oil pipe joint and a hollow bolt for oil; the linkage pump is internally provided with a front braking plunger chamber and a rear braking plunger chamber which are internally and respectively provided with a brake pump piston and a restoration spring; and the linkage pump is provided with an oil ring which is communicated with the front braking plunger chamber and the rear braking plunger chamber. The one-driving-four front-to-back linkage brake pump has the advantages of good braking effect and balanced and synchronous brake force.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a brake pump, in particular to a one-to-four front and rear linkage brake pump suitable for automobiles. Background technique [0002] The one-to-four front and rear linkage brake is a dual oil circuit, front and rear linkage braking device. Through the foot brake, the front and rear brakes work together to achieve the purpose of braking. According to market feedback, this type of brake has insufficient rear wheel braking force and out-of-synchronization of front and rear brakes. When braking, the front wheels of the vehicle have been locked, and the rear wheels are still rotating, making it difficult to control the direction. There are even more dangerous situations such as deviation. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems in the existing technology, and propose a one-drag four-front and rear linkage b...
