Bench test fixture for performance of steering boxes

Abstract

The invention aims to provide an adjustable bench test fixture for the performance of steering boxes. The bench test fixture for the performance of the steering boxes meets requirements of retest for the performance of the steering boxes, and comprises a base. A support plate is perpendicularly fixed onto the base, a slider capable of being adjusted in the height direction and the horizontal direction is arranged on the support plate and is movably provided with a steering box fixing plate via a rotary shaft, locking nuts used for locking the rotary shaft are mounted at ends of the rotary shaft, and the rotary shaft and the steering box fixing plate are integrated. The bench test fixture for the performance of the steering boxes is simple in structure, low in manufacturing cost, convenient to mount and adjust and high in universality and practicality, test requirements of the steering boxes with different sizes can be met, and preparation time for a bench test for the performance of a steering box is greatly shortened.

Description

technical field [0001] The invention belongs to the technical field of auto parts testing, and is particularly designed to a steering gear performance bench test fixture. Background technique [0002] At present, ordinary hydraulic power steering systems are still mostly used in the automotive field. As the most important component of ordinary hydraulic power steering systems, the performance curve of the steering gear directly determines the performance of the steering system. The structure and space of the whole vehicle are different, and the versatility of the steering gear is relatively poor, which leads to a large variety of steering gear performance bench test fixtures. Each steering gear corresponds to a kind of fixture, and the design and manufacture of the fixture takes at least half Monthly cycle, which not only wastes cost, but also seriously wastes test preparation time, which affects the development cycle of the steering gear, and even has an impact on the deve...
