Study on a New Type of Differential with Variable Ratio for Off-road Vehicles
摘要
Abstract
A new type of differential with variable ratio for off-road vehicles was put forward, in which the transmission ratio varied at a circle of the planetary gear, which had half the number of the teeth of the half-axle gear. The variable range of ratio can go extreme as much as ±40% , resulting in locking coefficients of 2. 33(theoretical) and 3. 15(practical), which would be of great help to improve the passing capability of the vehicle. Based on the round trip mapping algorithm with preserved geodesic curvature between a sphere and a plane, the design methods of the pitch curves as well as the tooth profiles were presented, and an actual case study was illustrated to show the effectiveness of the new differential.关键词
