Abstract

The invention provides a transmission, a driving system with the transmission, and a control method for the driving system. The transmission comprises a first shaft, a first clutch, a second clutch, a planetary gear mechanism and a second shaft which are coaxial, wherein the planetary gear mechanism comprises a sun gear, a gear ring, a planetary gear and a planetary carrier; the planetary gear can rotate on the planetary carrier and rotate around the sun gear and the gear ring; a driving disc of the first clutch, the first shaft and the gear ring are integrally arranged; the sun gear and a driven disc of the second clutch are integrally arranged; and the planetary carrier, a driven disc of the first clutch and the second shaft are integrally arranged. Through the arrangement, a multi-shaft design is avoided, the number of gears is reduced, the design, manufacturing and assembly of a transmission system are greatly simplified through a group of planetary gear mechanism and a few clutches, cost is reduced, the total weight of equipment is reduced, and the requirement on driving devices such as a motor and an engine is reduced.

Description

【Technical field】 [0001] Generally speaking, the present invention relates to the field of variable speed transmission; more specifically, the present invention relates to a speed change device, a driving system including such a speed change device and a control method thereof. 【Background technique】 [0002] Transmission (transmission) is often called "gearbox" in vehicles, especially automobiles, and is a device for mechanical power conversion. Usually it converts high-speed, low-torque mechanical power generated by a power source (internal combustion engine or electric motor) into more efficient low-speed, high-torque power to drive a mechanical device. A special transmission may also be used to increase the speed and reduce the torque. The transmission installed on the car usually has several different speed / torque conversion ratios, usually called "gears" or "gears", to meet the different requirements for the combination of speed and torque at different driving speeds....
