Abstract

The invention discloses a brake hydraulic pipeline, a brake hydraulic system and a vehicle. The brake hydraulic pipeline comprises a brake hard pipe, a connecting piece, a brake hose and a first noise reduction strip, and a first flow channel is formed in the brake hard pipe; one end of the connecting piece is connected with the brake hard pipe, and a second flow channel communicated with the first flow channel is formed in the connecting piece; one end of the brake hose is connected with the other end of the connecting piece, and a third flow channel is formed in the brake hose; the first noise reduction strip is located in the brake hose, a first noise reduction flow channel is formed in the first noise reduction strip, and the two ends of the first noise reduction flow channel communicate with the second flow channel and the third flow channel correspondingly. According to the brake hydraulic pipeline disclosed by the embodiment of the invention, the composite noise reduction pipeline is manufactured in the pipeline assembly by utilizing the flexibility characteristic of the brake hose and the noise reduction principle of the expansion chamber of the first noise reduction strip, so that some pump source pulsation is reduced, and the propagation of mechanical vibration frequency noise in the lower end pipeline and the hydraulic booster is reduced.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a brake hydraulic pipeline, a brake hydraulic system and a vehicle. Background technique [0002] The energy of the hydraulic booster of the existing model comes from the steering pump, which is a vane pump. When it works and rotates, it will generate mechanical friction, vibration noise and fluid pulsation noise. Part of the noise will be transmitted directly to the air through the casing; part of it will be transmitted through the output The port is pulsated by a certain fluid pulsation frequency and pressure, and is output to the pipeline through the fluid carrier wave and then spreads into the air. [0003] Noise transmitted to the surroundings through the hydraulic pipeline: a. Transmission of a certain amount of mechanical and fluid pulsation noise from the steering pump source; b. When the pulsating fluid passes through the pipeline, the pipeline will vibrate and resonate noise; c....
