A brake pipeline connection and fixing structure

Abstract

The invention discloses a brake pipeline connection and fixing structure, which comprises a brake hard pipe joint, a brake hose joint, a shock absorbing assembly and a mounting bracket arranged between the brake hard pipe joint and the brake hose joint , the lower end of the brake hard pipe joint passes through the shock absorber assembly, and is threadedly connected with the upper end of the brake hose joint passing through the mounting bracket, and the two communicate internally; the upper part of the brake hard pipe joint is configured with an upper limit The lower part of the brake hose joint is equipped with a lower limiter; the upper part of the shock absorber assembly is in contact with the upper limiter, and the lower part of the shock absorber assembly is in contact with the installation bracket; the lower surface of the installation bracket is in contact with the upper limiter. The lower limit piece is in contact; the shock absorbing assembly includes a U-shaped clip and a shock-isolating ring. The beneficial effect of the present invention is: the external vibration of the present invention performs a first-stage shock absorption through the elastic deformation of the U-shaped clip, and then realizes the second-stage axial movement from the brake hose joint to the brake hard pipe joint through the function of the shock-absorbing ring. damping.

Description

technical field [0001] The invention relates to a mechanical connection structure, in particular to a brake pipeline connection and fixing structure. Background technique [0002] The brake pipeline is an important structure used to connect the ESC (electronic stability control system) and the caliper, and plays the role of transmitting hydraulic pressure. The existing brake pipeline is mainly composed of brake hard pipe and brake hose. The brake hard pipe is a rigid pipeline, which is generally fixed on the vehicle body; the brake hose is a flexible pipeline, which is excited by the driving process of the vehicle. As for vibration, if the joints of the two are not fixed well, it may cause problems such as torque attenuation, joint falling off, and brake fluid leakage, so the joint connection and fixing structure of the two is very important. [0003] In the prior art, there is a related connection structure for connecting the brake hard pipe and the brake hose. For example...

Problems solved by technology

However, this connection structure uses a support to connect to the brake hard pipe, and the side of the support facing the bracket is suspended in the air. During the assembly process, the support will rotate with the nut and has no anti-rotation function; Provides a first level of shock absorption for the brake line, poor shock resistance
