Test device for measuring and simulating brake hose

Abstract

The invention provides a test device for measuring and simulating a brake hose, which belongs to the technical field of vehicles and aims at solving the problem of how to simulate the mounting environment of the brake hose in a real vehicle. The test device comprises a frame body; two mutually-parallel and parallelly-arranged X scale guide rods are fixed on the frame body; at least two Y scale guide rods are connected between the two X scale guide rods in a sliding mode; the Y scale guide rods are vertical with the above two X scale guide rods; Z scale guide rods arranged along the vertical direction and vertical with the Y scale guide rods are connected in a sliding mode onto the Y scale guide rods; and a hose clamping device for clamping and fixing the brake hose and capable of adjusting the mounting angle of the brake hose is connected in a sliding mode onto the Z scale guide rods. The test device can simulate the mounting position and the mounting angle of the brake hose in the real vehicle, the brake hose sample can be prevented from being changed repeated for assembly verification in a vehicle loading stage, the development period of the brake pipeline is shortened, and teh development cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to a test device for measuring and simulating brake hoses. Background technique [0002] Automobile braking system refers to a series of braking devices specially installed on automobiles, the purpose of which is to make the driving car decelerate or even stop forcibly according to the driver's requirements, or to make the car park stably under various road conditions. Among them, the brake hose is a component used in the automobile braking system. Its main function is to transmit the brake medium in the automobile brake to ensure that the braking force is transmitted to the brake shoe or brake caliper of the automobile, and then Generate braking force, making the car brake effective at any time. [0003] For example, Chinese patent [application number: 201420781228.4; authorized announcement number: CN204383450U] discloses an automobile brake hose assembly, including a first hose...

AI Technical Summary

Problems solved by technology

[0004] However, in the known development of brake hoses, the analysis is done only through development engineering experience to determine the brake hose length and installation position

However, because the above-mentioned brake hose is made of flexible material, with characteristics such as uncertain trajectory and adjustable expansion, the analysis results are different from the actual loading, and the pipeline is too short, too long or the direction is different, resulting in a gap with the peripheral parts. small or interfering

In order to ensure that there is an appropriate gap between the brake hose and the surrounding parts during the running of the vehicle, it is often necessary to verify the brake hose several times to determine the appropriate length and installation position of the brake hose, which greatly reduces the Improved vehicle assembly efficiency of brake hoses
