Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobile parts testing, in particular to a position regulating device for a steering gear input shaft. Background Art
[0002] The steering gear is an important part in a car. It is used to appropriately transform the steering torque and steering angle from the steering wheel and then output them to the steering rod mechanism to make the car steer.
[0003] Impact force testing is required in the early stage of steering gear development to verify the mechanical properties of the steering gear during impact. According to the test requirements, the impact force test of some models of steering gears requires the steering gear input shaft to be fixed. In order to ensure the validity of the test data, the steering gear needs to be assembled in a simulated vehicle position during the impact force test. And the impact force test generally requires testing three positions, namely the upper jump position, the lower jump position, and the design position. The steering gear needs to be changed in the X, Y, and Z directions at different test positions. Since the impact force test equipment is fixed, in order to fix the steering gear input shaft, it can only be adjusted by moving the input shaft fixing tooling.
[0004] In the prior art, input shaft fixtures need to be designed separately for different types of steering gears. This method not only requires tens of thousands of yuan in design and production costs, but also requires different fixtures to be replaced at different locations during testing, which takes several hours of testing time.
