The Scheme of Lightweight Integrated Mixing Transmission Based on Flat Motor for Tracked Vehicle

According to the requirements of tracked vehicles for high power supply capacity，high volume power density，high mobility，multi-function，light weight，etc.，a lightweight integrated mixing transmission based on flat motor is proposed by using the multi-objective comprehensive evaluation method to optimize a variety of transmission types，such as integrated hydro mechanical transmission，composite electro-mechanical transmission，pure electric drive，comprehensive heavy hybrid drive and light comprehensive hybrid drive. In the proposed scheme，the development trend and technical maturity of integrated hydro mechanical transmission and electric drive technology are considered.The proposed scheme can effectively tackle the problem of insufficient power supply capacity of integrated hydro mechanical transmission，improve the volume power density，enhance the mobility， expand the function of vehicle power cabin，and effectively control the weight.For the proposed scheme，the parameters were matched，and the maneuverability was predicted. The results show that the proposed scheme can effectively solve the layout and installation of vehicle power cabin，and avoid other problems caused by the long direction of vehicle compared to the original scheme， and the structure is reasonable and feasible.
