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.

    本发明公开了一种制动液压管路、制动液压系统及车辆,包括:制动硬管、连接件、制动软管和第一降噪条,制动硬管内具有第一流道;连接件的一端与制动硬管相连,连接件内形成有与第一流道连通的第二流道;制动软管的一端与连接件的另一端相连,制动软管内形成有第三流道;第一降噪条位于制动软管内,第一降噪条内形成有第一降噪流道,第一降噪流道的两端分别与第二流道和第三流道连通。根据本发明实施例的制动液压管路,通过利用将制动软管的挠性特性与第一降噪条的扩张室减噪原理,在管路总成中制成的复合式减噪管路,降低了一些泵源脉动,降低了机械振动频率噪音在下端管路以及液压助力器中的传播。
