Problems solved by technology

At present, in the existing two-speed transmission system, the transmission system usually adopts a planetary row structure, which eventually leads to a larger volume after the transmission system is integrated, poor flexibility in placement, large installation limitations, and is not conducive to assembly. During the process, the transmission system and drive axle system are installed separately. Usually, the system is installed in a horizontal arrangement. High vehicle assembly cost, poor installation flexibility, and more importantly, the drive axle system does not have a transmission function

Abstract

The invention discloses a variable-speed drive axle system which comprises a motor, a differential mechanism and a speed changer, and the differential mechanism and the speed changer are integrated. The speed changer comprises a first gear shifting set, a second gear shifting set, a transmission input gear, a first transmission shaft and a second transmission shaft. A drive axle comprises a differential mechanism input set and a differential mechanism output set. The first transmission shaft is parallel to the second transmission shaft. The first gear shifting set and the motor are coaxially connected to the first transmission shaft. The transmission input gear and the second gear shifting set are coaxially connected to the second transmission shaft. The transmission input gear and the differential mechanism output set are engaged and perpendicularly connected. The transmission input gear outputs power to wheels through the differential mechanism output set. According to the variable-speed drive axle system, the speed changer of a parallel-shaft structure is adopted, the speed changer and the differential mechanism are perpendicularly arranged to be integrated to the drive axle, the size of the system is effectively reduced, and the drive axle has a speed changing function.

Description

technical field [0001] The invention relates to the technical field of mobile new energy vehicles, in particular to a variable speed drive axle system. Background technique [0002] With the development of science and technology, the problems of energy constraints and environmental pollution are becoming more and more serious. Vigorously developing new energy can effectively solve energy and environmental problems and achieve sustainable development. With the improvement of living standards, more and more people own cars. With the increase of the number of cars, it is easy to cause problems such as road congestion and traffic accidents. More importantly, a large number of cars quickly consume energy such as oil. At the same time, the pollution of the environment has been greatly aggravated. Therefore, in the development of new energy, the development of new energy vehicles is particularly important. [0003] With the maturity of new energy technology, the drive system has a...
