One-drive four-wheel-motion pivot steering device

Abstract

The invention relates to a one-drive four-wheel-motion pivot steering device which is composed of a drive system and a steering system. Axles of four wheels are connected with a drive mechanism through telescopic cardan shafts. One transmission output shaft in a cross-shaped commutator is connected with a motor. Bevel gears are fixedly connected to transmission output shafts driving the two wheelson the same side. The other two transmission output shafts are connected with sliding gears. One end of each telescopic cardan shaft is connected with the axle of the corresponding wheel, and the other end of each telescopic cardan shaft is connected with a bevel gear. The bevel gears on the telescopic cardan shafts driving the two wheels on the same side are in engaged connection with the bevelgears on the two corresponding transmission output shafts of the cross-shaped commutator. The bevel gears on the telescopic cardan shafts driving the two wheels on the other side are in engaged connection with the sliding gears on the other two transmission output shafts of the cross-shaped commutator. Steering shafts of the four wheels penetrate through a vehicle chassis and then are connected with bevel gears B. The bevel gears B on the steering shafts of the wheels located at two diagonal angles are in engaged connection with bevel gears A at the two ends of the same connecting rod.

Description

Technical field [0001] The invention relates to a vehicle omni-directional movement system, in particular to a steering device which can realize the three movement modes of vehicle forward, lateral movement and in-situ rotation. Background technique [0002] In daily life, due to the limitation of the driving structure of the car, when encountering parking and warehousing, L-shaped narrow roads, and complex road conditions, novices are often at a loss, waste a lot of time for car owners, and cause congestion in severe cases. [0003] Due to market demand, many universities and research institutions are studying all-round mobile platforms. At present, it is divided into two types of omnidirectional systems with steering mechanism and without steering mechanism. Similar programs are: [0004] 1) The in-situ steering system with steering mechanism adds a set of steering devices on the basis of ordinary gear trains to control the direction and movement direction of the wheel hub plane,...
