Problems solved by technology

The butter between the two plates of each group of steel plates needs to be maintained and added frequently, otherwise the friction coefficient will increase and people will not be able to push the car horizontally. With a little force, it appears that the mark has crossed the centerline of the traction track
This method also needs to push the cart back and forth many times before the test vehicle can be aligned, which wastes time and reduces the efficiency of the crash test

Embodiment Construction

[0065] The present invention will be described in further detail in conjunction with the following, so that those skilled in the art can implement it with reference to the description.

[0066] Such as figure 1 , figure 2 As shown, the present invention provides an electric straightening device for straightening a crash test vehicle. The drive plate is driven to move by a geared motor, and the driven device is driven to move laterally by the front and rear axles of the vehicle, thereby realizing the test vehicle. Lateral movement adjustment.

[0067] In this embodiment, the crash test vehicle is a four-wheeled vehicle, and the electric straightening device for straightening the crash test vehicle includes: a first driving device 100, a second driving device 300, a first driven device 200 and the second driven device 400, wherein the structure of the first driving device 100 and the second driving device 300 are identical, the structure of the first driven device 200 and the s...

Abstract

The invention discloses an electric straightening device for straightening a collision test vehicle. The electric straightening device comprises: at least two driving devices, at least two driven devices, wherein the at least two driven devices and the driving devices are symmetrically arranged along the longitudinal center line of the vehicle in a one-to-one correspondence manner. Each driving device includes: a first base including a first sliding portion and a power portion; a gear motor which is arranged on the power part; a ball screw, wherein the ball screw is fixed to the power part, the ball screw is parallel to the axis of the first base, and the ball screw is connected with the gear motor; a driving plate, wherein the driving plate is arranged on the first sliding part in a sliding manner, and the driving plate is movably arranged on the ball screw. Each driven device includes: a second base including a second sliding portion and a reinforcing portion; and a driven plate which is arranged on the second sliding part in a sliding manner. According to the invention, the to-be-collided test vehicle can be accurately straightened.

Description

technical field [0001] The invention relates to the technical field of automobile collision test, and more specifically, the invention relates to an electric straightening device for straightening a collision test vehicle. Background technique [0002] In recent years, with the continuous growth of domestic automobile production and sales, the mandatory items of new domestic automobile products, the amount of finalized tests, and the amount of automobile research and development tests have also increased year by year. It is imminent to optimize the work of each link of the test, shorten the test preparation time, and greatly improve the test efficiency. [0003] Because the car crash test requires the route of the vehicle to reach the barrier, there is a certain limit to the deviation of the theoretical trajectory in any direction in the lateral direction, which is generally called the offset. In order to ensure that the offset of the car crash test is within the allowable ...
