AI Technical Summary

Technical Problem

The existing four-wheel drive chassis dynamometer lacks left and right side limiting structures for the vehicle, which causes the car wheels to easily deviate during the test, resulting in wear and affecting the test efficiency.

Method used

A testing platform for new energy vehicles was designed, which adopts a limit wheel and lifting hydraulic cylinder structure. The position and height of the limit wheel are adjusted by adjusting the lead screw and sleeve to ensure that the car tire does not shift during the test. It is suitable for different car models and tire sizes.

Benefits of technology

It effectively prevents car tires from shifting during testing, ensuring the normal progress of the test, reducing wear, and is suitable for different car models and tire sizes, thus improving testing efficiency.

Abstract

This utility model discloses a testing platform for new energy vehicles, applied in the field of automotive testing equipment technology. It includes a first mounting base and a second mounting base. Both the first and second mounting bases have grooves on their tops. A lifting seat is installed inside each groove. A movable groove is symmetrically formed on the top of each lifting seat. A movable block is installed inside each movable groove. A support column is installed on the top of each movable block. Limiting wheels are fixedly fitted onto the surface of each support column. An adjusting screw, threadedly connected to the movable block, is rotatably connected inside the movable groove. This utility model, by installing movable blocks on the lifting base, allows the movable blocks to move when the adjusting screw is rotated. This causes the support column on top of the movable block to drive the limiting wheels to contact the outer surface of the vehicle tires. The four limiting wheels limit the movement of the four tires, preventing tire displacement during testing.
