Abstract

The invention discloses an automatic gearbox which comprises a gears gear driving system and a gear shift mechanism executing system. The automatic gearbox is characterized in that the gear shift mechanism executing system comprises a control device, a gear stabilizing device, a gear shift shifting device and a transmission buffering device. The gear stabilizing device is an elastic angle tooth device or a reverse action device, the gear shift shifting device is a key clutch or a combined sleeve clutch, the control device is connected with the reverse action device or a gear shifting spring matching with the elastic angle tooth device to achieve the function of the key clutch or the combined sleeve clutch, and the gears gear driving system is forced to shift gear to achieve speed change. A steel disc synchronous elastic combined sleeve of the combined sleeve clutch is assembled between a first gear sliding gear and a second sliding gear, and a gear shaft is provided with a torque limiter. The automatic gearbox is low in manufacture cost, high in transmission efficiency, long in service life, and capable of being assembled on various vehicles and agricultural machinery, and the using of the automatic gearbox is power-saving and fuel-saving.

Description

technical field [0001] The invention relates to an automatic transmission for gear shifting in motor vehicle transmission, in particular to a fully automatic gear shifting device for electric vehicles, fuel vehicles and hybrid vehicles, which belongs to the technical field of mechanical transmission. Background technique [0002] The existing continuously variable automatic transmission has low mechanical efficiency, is easily damaged, and has unstable performance; the mechanical automatic transmission is large in size and has various control systems, which is not suitable for small vehicles; the hydraulic automatic transmission has low transmission efficiency and is expensive; the mechanical manual transmission is cumbersome to operate , not convenient enough to use. [0003] In the prior art, in the transmission disclosed in the Chinese invention patent application (application number: 201010164267.6), the speed shifting device is that one end of the gear shaft is fixed wi...
