Problems solved by technology

Through the description of the above working process, for a transmission with one intermediate shaft or two intermediate shafts, in the power transmission process, the power needs to be transmitted from the input shaft to the intermediate shaft through gear meshing, and then to the output shaft through gear meshing. Therefore , when the power is transmitted, the power needs to go through at least two pairs of gear pairs from the input shaft to the output shaft, and the gear mesh must have energy loss, which reduces the transmission efficiency of the transmission
In addition, when increasing the number of gears for a rear-drive transmission, the number of gear pairs on the intermediate shaft and the output shaft is required, which makes the entire transmission complex in structure and heavy in weight
[0005] To sum up, it can be seen that the transmission in the prior art has difficulty in increasing the number of gears, and after increasing the number of gears, the structure is complex, the weight is heavy, and there are also problems of low power transmission efficiency

Embodiment Construction

[0036] The core of the present invention is to provide a mixed-connection double countershaft transmission, which can reduce the length of the transmission compared with the existing transmission with the same number of gears. Another core of the present invention is to provide an automobile with the above-mentioned mixed-connection double countershaft transmission.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] Such as figure 1 and figure 2 As shown, the present invention discloses a mixed dou...

Abstract

The invention discloses an automobile and a mixed-connected double-intermediate-shaft transmission thereof. The mixed-connected double-intermediate-shaft transmission comprises an input shaft, a first intermediate shaft, a second intermediate shaft, an output shaft, gears installed and distributed on all the shafts, a gear shifting mechanism, a shell, bearing oil seals and other components. In the power transmission process, the second intermediate shaft can be connected to the first intermediate shaft to transmit power and can be directly connected with the input shaft without being connected with the first intermediate shaft to transmit power, and therefore the transmission efficiency of the transmission is improved. The gear number of the mixed-connected double-intermediate-shaft transmission is equal to the product of the number of gears on the first intermediate shaft and the number of gears on the output shaft, however, the gear number of an existing transmission is usually equal to the sum of all the gear meshing pairs of the transmission. By the adoption of the mixed-connected double-intermediate-shaft transmission of the automobile, on the premise that the size and the weight of a traditional 6-gear transmission are not changed, the transmission with 8 gears or 9 gears can be achieved. The power performance, the fuel economical efficiency and the driving and riding comfort of the whole automobile can be remarkably improved, and the transmission is particularly suitable for being used as an AMT.

Description

technical field [0001] The invention relates to the technical field of transmissions, and more specifically relates to an automobile and a mixed-connection double countershaft transmission thereof. Background technique [0002] Since the transmission was born, it has become an indispensable part of the car, and there are more and more types, and the development of the transmission tends to be diversified. Mainly divided into: manual transmission (MT), hydraulic automatic transmission (AT), electromechanical automatic transmission (AMT), continuously variable transmission (DCT). [0003] At present, the vast majority of passenger cars are front-wheel drive, and the matching transmission is a two-shaft transmission, including an input shaft and an output shaft, and the two shafts are arranged in parallel. The input shaft is also the driven shaft of the clutch, and the output shaft is also The drive shaft of the main reducer. In order to realize the change of the gear positio...
