Column support system

Abstract

The invention provides a column supporting system which is formed by an experimental platform and two sets of column supporting mechanisms. Each set of the column supporting mechanism is formed by a cross sliding platform, an internal sliding module group and a lifting motor. The cross sliding platform comprises a lower fixed frame, a lower sliding guide column, an upper platform, an upper fixed frame and an upper sliding guide column. Both the lower fixed frame and the lower sliding guide column are fixed on the experimental platform. Both the upper fixed frame and the upper sliding guide column are fixed on the upper platform. The upper platform can move left and right on the lower sliding guide column. The internal sliding module group comprises two motion guide columns and a sliding sleeve. The upper part and the lower part of the internal sliding module group are provided with a rotating mechanism respectively. The rotating mechanism of the lower part of the internal sliding module group can move front and back on the upper sliding guide column. According to the system, the experiment needs of different directions, different angles and different positions of a vehicle steering column test platform are realized, the adjustment is simple, the replacement is convenient, the system is suitable for different types of prototypes, in addition, electric control lifting is employed, and the system has the advantages of convenient operation, high degree of automation and elegant appearance.

Description

technical field [0001] The invention relates to the technical field of automobile steering control, in particular to a column support system of an automobile steering column test bench. Background technique [0002] The steering column mainly supports and fixes the steering wheel in the car, and transmits the torque applied by the driver through the steering wheel. As people have higher and higher requirements for driving comfort, the position-adjustable four-way adjustable steering column is widely used in automobiles, and the quality inspection of the column before leaving the factory is particularly important. At present, there are very few testing equipments for the four-way adjustment durability of the steering column. Some steering column manufacturers use manual testing machines. The existing automatic testing equipment for the adjustment and durability of the steering column also has single function, complex structure, and inaccurate simulation. Human operation on t...

Problems solved by technology

At present, there are very few testing equipments for the four-way adjustment durability of the steering column. Some steering column manufacturers use manual testing machines. The existing automatic testing equipment for the adjustment and durability of the steering column also has single function, complex structure, and inaccurate simulation. Human operation on the steering wheel, inaccurate measured data, lack of reusability, and lack of wide applicability to various types of columns, etc. These problems limit the overall improvement of the steering column adjustment durability performance testing technology. Currently The industry's requirements for steering column tests are reflected in two aspects: First, because the safety performance of each new model needs to be repeatedly verified, tests in different directions, different angles and different positions are frequently carried out, and the experimental equipment should be able to adapt to multi-directional, Repeated use; Second, due to the differences in the experimental conditions required by different structural models, the experimental equipment should have strong general performance
