Research of the Traction Control of Flexible Work Surface Belt Drive of Heavy Duty Construction Vehicle by Lou Jie

“…To reduce the energy consumption of heavy duty construction vehicle pollution,and improve the capacity of the complex conditions of the vehicle,the multi-metal complex with stepless transmission and front / rear axle torque distribution device in the traditional drive system are imported,a new mathematical model of heavy duty four-wheel heavy duty construction vehicle is established,finally,a four-wheel drive heavy duty construction vehicle traction integrated control strategy is obtained.The results show that large ratio change conditions required for the engine reaches maximum speed of the longest and highest speed reached a minimum;small ratio change conditions can achieve high speed,the speed curve more smooth and steady acceleration phase speed change under the conditions of large ratio rate change;after the introduction of traction control system,slip phenomenon can be well suppressed over a driving wheel,the drive wheel speed control range of the space in the target vehicle speed.…”
