Generally, the test speed is the same speed when turning. However, during actual driving, the rotation speed may vary due to terrain, which may cause damage to the drive module. Since this is not reflected in the experiment, effective data cannot be measured, thus affecting the use effect after leaving the factory. Therefore, it does not meet the speed measurement requirements. Summary of the Invention

[0008] In the above-mentioned steering drive module assembly for speed measurement, the balance frame consists of an L-shaped bottom frame connected to the axle bridge and a straight-line long frame arranged on and connected to the L-shaped bottom frame. The straight-line long frame is inclined. An installation seat connected thereto and for installing the slewing support seat is arranged on the straight-line long frame, and a buffer unit for buffering is arranged between the installation seat and the L-shaped bottom frame.

[0009] In the above-mentioned steering drive module assembly for speed measurement, the buffer unit is an oil cylinder with a telescopic rod. One end of the oil cylinder is connected to the mounting seat, and the telescopic rod at the other end of the oil cylinder is connected to the L-shaped chassis. An installation groove for installing the telescopic rod is provided on the L-shaped chassis, and the L-shaped chassis is connected to the telescopic rod through a connecting shaft.

[0010] Compared with the prior art, the steering drive module assembly for speed measurement of the present invention has the following advantages:

[0011] 1. Speed control units for controlling the rotation speed of the tires are provided at both ends of the axle bridge and are connected thereto. The steering unit is a slewing support seat provided on the balance frame and connected thereto. An output motor for driving the slewing support seat is provided on the side wall of the slewing support seat. With the above structure, steering tests at different speeds can be carried out.
