Technical Field

[0002] Electric crawler vehicles refer to "cars" that use crawler running systems instead of wheel running systems. This type of vehicle has low ground pressure, small sinking, strong adhesion and strong driving ability. The cab, cargo platform or carriage are basically the same as those of ordinary wheeled vehicles. Generally, according to the running system structure, they can be divided into three types: semi-tracked type with sleds or wheels on the front axle (driven axle) and tracks on the rear axle, full-tracked type with tracks on both the front and rear axles, and wheel-tracked type with wheels and tracks interchangeable.

[0003] Prior art CN202243744U is an electric crawler transport vehicle, which can effectively utilize the kinetic energy of the high-speed rotation of the driven wheels of the crawler transport vehicle to generate electricity, reasonably convert mechanical energy into electrical energy, and further provide electrical energy for the transport vehicle, thereby avoiding the waste of kinetic energy. Since the electric crawler transport vehicle of the utility model is provided with an outer rotor generator, the driven wheels can be automatically powered and charged during driving, which greatly reduces the operating cost and saves energy and is environmentally friendly. However, there are still certain problems, and the specific problems are as follows;

[0004] At present, most electric crawler vehicles on the market use shock-absorbing springs to cushion the electric crawler vehicles while transporting products. This shock-absorbing method has a poor shock-absorbing effect, which causes the goods inside the electric crawler vehicle to shake and be damaged, thereby causing property loss.
