Embodiment Construction

[0022] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] see Figure 1 to Figure 4 As shown, the present invention provides a kind of vehicle steering system resistance test device, comprising:

[0024] The fixed frame 1 is placed horizontally on the ground and is used to support the test platform 3 and the wheels on it. On the top surface of the fixed frame 1, there is a first arc-shaped groove opening downward, and the depth of the first arc-shaped groove is about 5mm , an angle scale 2 is provided on the outer edge of the first arc-shaped groove.

[0025] Test platform 3, test platform 3 is an arc-shaped plate, wherein, the arc-shaped surface of the arc-shaped plate is on the same circular surface, this design considers that when the subsequent force is applied, the force arms on the surface...

Abstract

The invention discloses a finished automobile steering system resistance testing apparatus comprising a fixing rack, a testing platform, a ball and a loading device. A first arc-shaped groove downwardly opening is formed on the top surface of the fixing rack; angle scales are arranged on the external edge of the first arc-shaped groove; the testing platform is an arc-shaped plate; an arc-shaped surface of the arc-shaped plate are on the same circuit surface; the bottom surface of the testing platform is tightly close to the arc-shaped surface and is provided with a second arc-shaped groove sharing the same circle center of the testing platform; two ends of the second arc-shaped groove are opened; the testing platform is horizontally arranged on the fixing rack; a scale pointer is protruded from the middle of the arc-shaped surface; the ball is arranged between the first and second arc-shaped grooves; the fixing rack is in a slideable connection with the testing platform via the ball; and the loading device works on the arc-shaped surface along a tangential direction of the arc-shaped plate to pull the testing platform to rotate in the fixing rack. The invention further provides a finished automobile steering system resistance testing method; and the rotary testing platform is employed to bear wheels and real conditions are simulated during the test, so accurate test can be achieved.

Description

technical field [0001] The invention relates to the field of vehicle steering system detection, in particular to a device and method for testing resistance of a vehicle steering system. Background technique [0002] In order to reduce the workload of the driver and ensure the straight-line driving performance of the car, the front steering wheel is required to have an automatic return to alignment function. When the car is turning, it mainly relies on the caster drag generated by the wheel caster angle and the centering moment formed by the centrifugal force to make the wheel return to the center. The centering torque is determined by the steering wheel alignment parameters and the wheel angle. Therefore, the wheel alignment parameters affect the wheel alignment performance. , however, when the design and calculation of the front wheel alignment meet the requirements, there will still be a problem of alignment difference. The main consideration is the influence of system res...
