Abstract

The invention is suitable for the technical field of transmissions, and discloses a gearbox for an electric vehicle. The gearbox comprises a motor, a transmission and a differential mechanism. The motor comprises a stator, a rotor and a motor shell. The transmission comprises a planet gear transmission device, a transmission gear set, an electromagnetic brake and a transmission shell. The differential mechanism comprises an output shaft and a differential mechanism shell. The motor is further provided with a motor output shaft. The planet gear transmission device comprises a planet carrier, a sun gear, a planet gear and an inner gear ring. The transmission gear set comprises a first-gear driving gear, a first-gear driven gear, a second-gear driving gear and a second-gear driven gear. The electromagnetic brake comprises a magnet yoke and an electric driving board. According to the gearbox for the electric vehicle, the area and the complex degree of a gearbox outer shell are effectively reduced, the size is small and exquisite, and the manufacturing cost is low; the technical problems of a large current and power consumption during starting, climbing and overloading of an existing electric vehicle are effectively solved, and therefore the overall performance and the market competitiveness of the electric vehicle are easily improved.

Description

【Technical field】 [0001] The invention relates to the technical field of transmissions, in particular to a transmission for electric vehicles. 【Background technique】 [0002] At present, internal combustion engine vehicles occupy most of the market, but internal combustion engine vehicles are facing two difficult problems of emission and shortage of oil resources. Starting from solving the energy crisis and environmental protection needs, the development of new energy vehicles represented by pure electric vehicles has attracted widespread attention from all over the world. [0003] Abroad, represented by Japan and the United States, are at the forefront of the world in the research of electric vehicles and hybrid vehicles. The number of hybrid vehicles in Japan reached 197,000 in 2004, mainly the third generation of Toyota Prius and Honda Civic. In the second generation, there are more than 20 varieties. The United States is accelerating the development of diesel hybrid pow...
