Problems solved by technology
Although there are many inventions about parallel shaft transmissions, some of these inventions are new technical solutions about the number and position of shafts, some are new technical solutions about the number and positions of gears, and some are about the number and positions of shift control mechanisms. However, due to the limitation of the size of the transmission and the torque that the transmission needs to bear, the gears of the current practical multi-clutch structure parallel shaft transmission can only reach 6 forward gears
According to the current transmission structure, if the gears are increased, either the structure is too complicated, or the structure is too large to be practical.

A parallel axle transmission adopting a wheel axle structure and consisting of multiple idler wheel gears is called as a multiwheel axle-structured transmission for short; and under the combined action of a multi-wheel axle structure of the multiwheel axle-structured transmission and fitting spline hub sleeve axle mechanism, two-way overrunning clutch mechanism and tooth embedded clutch mechanism, 12 forward gears and 4 reverse gears are reached in the size range of a traditional transmission. The multiwheel axle-structured transmission comprises an input shaft, a multiwheel axle, an intermediate shaft and an output shaft arranged in parallel, and corresponding gears and clutch devices. The multiwheel axle-structured transmission has the following characteristics: (1) the ratio of the gear number to the gear number is the minimum, so that the size of the transmission is relatively the minimum; (2) the ratio of gear shifting control elements to the gear number is the minimum, so that the structure of the transmission is relatively simple; (3) the total tooth ratio range is widened; and the vehicle power performance is improved; (4) the gears are dense and reasonable; and the gear shifting smoothness and the fuel economy are improved; and (5) a torsion increasing gear set is arranged for bearing higher torque.
Description
technical field [0001] The invention belongs to the field of transmissions, in particular to parallel shaft transmissions. Background technique [0002] The transmission is the most important transmission part in the power transmission system, especially in the car, the performance of the transmission directly determines the performance of the car, determines the transmission efficiency of the car, determines the fuel economy of the car, and determines the smooth shifting of the car sex and comfort. Due to the huge investment of automobile companies and research institutions all over the world, the automobile transmission technology has been improved and developed unprecedentedly. Therefore, it can be said that the transmission technology on automobiles is the latest technology in the field of transmission. At present, the main structure of automobile transmission is divided into two categories: manual transmission structure MT and automatic transmission structure AT. The s...
