Abstract
The invention discloses a multi-speed transmission and relates to the technical field of automobile transmission. The multi-speed transmission is used to solve the problems that an existing multi-speed transmission is large in size and complicated in arrangement. The multi-speed transmission comprises an input shaft, an output shaft and a middle shaft, wherein the input shaft, the output shaft and the middle shaft are arranged in parallel. Gears are sleeved on the input shaft, the output shaft and the middle shaft and comprise movable gears and fixed gears, and shifting synchronizers are arranged on one sides of the movable gears. Combination and separation of the movable gears and the corresponding input shaft, the corresponding output shaft and the corresponding middle shaft can be achieved through combination and separation of the shifting synchronizers and neighboring movable gears. The movable gears and the corresponding fixed gears form a plurality of gear pairs, and the plurality of gear pairs comprise a high-speed gear pair and a low-speed gear pair which both can transmit power from the input shaft to the middle shaft in switching mode, and at least three gear pairs which can transmit the power from the middle shaft to the output shaft in switching mode. The multi-speed transmission is used to transmit the power of an engine.
Description
technical field [0001] The invention relates to the technical field of automobile transmission, in particular to a multi-speed transmission. Background technique [0002] With the continuous development of the automobile industry and automobile technology, many automobile companies have higher and higher requirements for the performance of vehicles in all aspects, especially the power of the vehicle, and the power performance of the vehicle includes many aspects, among which the transmission is A very important aspect. [0003] Existing multi-speed transmissions can generally realize the power switching of more than 6 gears. According to the layout of the engine, some multi-speed transmissions adopt a horizontal arrangement (front front drive), and some adopt a tandem arrangement (front Rear drive), this type of transmission mostly uses a planetary gear mechanism. The planetary gear mechanism usually requires multiple shaft sleeves to operate together, which makes the bear...
