Embodiment Construction

[0028] The seven-speed transmission according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] like figure 1 , image 3 or Image 6 As shown, it is a specific embodiment of the seven-speed transmission of the present invention. The seven-speed transmission includes a transmission housing 10 . The transmission housing 10 is fixed with an input shaft 20 , an output shaft 40 and an intermediate shaft 30 that are parallel to each other. The input shaft 20 , the output shaft 40 and the intermediate shaft 30 . The shafts 30 are all sleeved with gears, and the gears include an empty movable wheel 60a and a fixed fixed wheel 60b. One side of the movable wheel 60a is provided with a shift synchronizer 70, and through the shift synchronizer 70 The combination and separation of the adjacent movable wheel 60a realizes the combination and separation of the movable wheel 60a with the corresponding input sha...

Abstract

The invention discloses a seven-gear transmission and relates to the technical field of transmissions, which is designed to further improve the dynamic property of a vehicle. The seven-gear transmission comprises a transmission casing; an input shaft, an output shaft and an intermediate shaft, which are parallel to one another, are fixed in the transmission casing; a gear is sleeved on the input shaft, the output shaft and the intermediate shaft and comprises movable gears which are loosely sleeved and fixed gears which are fixedly sleeved; a gear shifting synchronizer is arranged on one side of each movable gear; the movable gears can be combined with or separated from the adjacent movable gears through the gear shifting synchronizers so as to be capable of being combined with or separated from the input shaft, the output shaft and the intermediate shaft correspondingly; the gear comprises seven movable gears and seven fixed gears; and the seven movable gears and the seven fixed gears are meshed in pairs to form seven forward-gear gear sets with different transmission ratios. The seven-gear transmission is applicable to motor vehicles.

Description

technical field [0001] The invention relates to the technical field of transmissions, in particular to a seven-speed transmission on a motor vehicle. Background technique [0002] With the continuous development of the domestic automobile industry and automobile technology, many automobile enterprises have higher and higher requirements on the performance of the vehicle in all aspects, especially the power of the vehicle, which affects the power performance of the vehicle in many aspects. Among them, the transmission is a very important aspect. [0003] Usually, most of the vehicles used in daily life use manual transmission (MT) or mechanical automatic transmission (AMT), while manual transmission (MT) and mechanical automatic transmission (AMT) are mostly fifth and sixth gears. [0004] For example, a six-speed manual transmission (MT) or a mechanical automatic transmission (AMT) has six forward gear sets with different transmission ratios, so when switching six different...
