Traction Force and Climbing Capacity Theoretical Analysis of Hydraulic In-wheel Motor Drive System

摘要

The objective of this paper is to introduce a newly developed Hydraulic In-wheel Motor Drive System (HIMDS) mainly made up of a variable displacement pump and two motors. The new HIMDS is primarily applied to heavy truck to improve its passing ability when encountering the low- m roads. This paper Not only illustrates the structure and working principle of the system, but also gives a detailed description of calculation of the improvement in traction force and climbing capacity of the vehicle after working with HIMDS. The Simulation results show that after using the system, the vehicle traction force was increased by 23%, and the climbing capacity was improved by 30% mostly.
