Abstract
In order to improve the dynamic and economy of electric tracked vehicle, a new tooth band brake was designed to replace the wet multi-plate clutch in the planetary transmission. A numerical model of the braking process was proposed based on the structure and working mechanism of tooth band brake. The variation law of parameters was studied, including the rotating angle and speed, as well as the braking torque of the brake drum. Moreover, a bench test was conducted to verify the feasibility of the brake structure and the correctness of numerical model. The results show that the initial rotational speed of the brake drum has a dramatic effect on the braking time and braking torque; the higher the rotating speed is, the shorter the braking time and the greater the braking torque. Compared with the original device, the new structure, can not only increase the braking speed range, but also provide better working reliability and application prospects.
