Abstract

The invention relates to the technical field of speed reducers, in particular to a speed reducer and an automobile. The speed reducer comprises a shell, a planet row, a first gear, a second gear, a differential mechanism, a first connecting part and a second connecting part, the planet row comprises a gear ring, a planet carrier, a planet wheel and a sun wheel used for inputting power, the secondgear is in meshing connection with the first gear, the first gear drives the second gear to rotate, the differential mechanism is connected with the second gear, and the differential mechanism is usedfor outputting power and connected with automobile wheels and can drive the wheels to rotate, so that automobile driving is achieved. The first connecting part is used for connecting or separating the gear ring from the shell of the speed reducer, and the gear ring is used for adjusting the speed reducer to a first gear after being connected with the shell of the speed reducer; and the second connecting part is used for connecting the planet row into an integrated structure or separating the planet row into a split structure, and after the planet row is connected into the integrated structure, the planet row is used for adjusting the speed reducer to a second gear. The speed reducer has the advantages of being simple in structure and small in occupied space.

Description

technical field [0001] The present disclosure relates to the technical field of reducers, in particular to a reducer and an automobile. Background technique [0002] Facing the coming of the era of energy conservation, environmental protection and low carbon, the industrialization of environmentally friendly, efficient and pollution-free electric vehicles is a feasible change in automotive technology, which is not only about protecting the environment, but also related to future sustainable development. After more than 10 years of hard work, my country's electric vehicle independent innovation has made important breakthroughs, self-developed products have begun to enter the market in batches, the development environment has gradually improved, the industry has a good foundation for development, and has favorable conditions and comparative advantages for accelerated development. [0003] However, the existing electric vehicle is a three-shaft reducer, which has the problems o...
