Technical Field

The invention belongs to the technical field of vehicle braking systems, and particularly relates to a vacuum braking oil pipe assembly and a vehicle.

Background

The existing vacuum brake oil pipe assembly mainly comprises a nylon pipe, a one-way valve, an atmospheric pressure sensor, a tee joint, a rubber pipe, a hoop and the like. In the development process of a new vehicle type, parts of the vacuum brake oil pipe assembly needing to be redeveloped generally comprise a nylon pipe and a rubber pipe, wherein the development cycle of the rubber pipe is longer than that of the nylon pipe, and the requirements on sample pieces and the purchasing time are examined. And the rubber tube of the vacuum brake oil tube assembly is connected with the nylon tube through the hoop, so that the risk of rusting can exist for a long time. Moreover, when the vacuum brake oil pipe assembly is assembled with a vehicle body, all parts of the vacuum brake oil pipe assembly need to be assembled with the vehicle body respectively, and because the parts of the vacuum brake oil pipe assembly are too many, more connecting pieces are needed, the assembling links are many, the assembling difficulty is high, and the assembling efficiency is low. The vacuum brake oil pipe assembly has more parts, and the difficulty in sealing is increased.
