Abstract

In order to realize the miniaturization and electrification of heavy vehicles, this paper innovatively puts forward a two-speed transmission device equiped with electrically controlled toothed band brakes. The dynamic models of the planetary gear and toothed band brake are derived, and the shift strategy is established to achieve the optimal dynamic performance. Moreover, the gearshift characteristics under different working parameters are studied to verify its feasibility. The results demonstrate that the toothed band brake has a short braking time and contributes to good shift performance, thus has potential for application. The effect of synchronous speed and actuator speed on shift performance is also analyzed. The increase of both speeds is beneficial to speed up the shift time, but lead to increased shift impact. The application of such a brake offers the possibility of full-electric and lightweight for electric vehicles.
