By building the kinematic model, the kinematic analysis was conducted for the speed properties of the mechanism and the movement rules and space of the middle part. The electric wheel was simulated using ADAMS software and the results showed that it was feasible to use self-lubricating composite material PEEK in the structural design to solve the wear problems existed in the friction pairs of the cross slider mechanism. According to the simulation results, the inner diameter, outer diameter and the length of sliding channel were designed and calculated. The mechanical efficiency of the transmission mechanism was analyzed and the calculated efficiency was 98.8%.
