Embodiment Construction
[0011] The present invention is committed to providing a six-speed transmission for vehicles with more superior performance. The existing six-speed transmission transmission system for vehicles such as figure 1 shown. Because the technology of the six-speed transmission transmission system for vehicles is relatively mature, especially the design of the power transmission route is very complicated, and there are too many involved, so it is very difficult to design a new power transmission route. The method adopted in this specific embodiment is to optimize the design of its transmission system, specifically by rationally arranging the position of the clutch hub assembly, brake and one-way clutch, so that the structure of the six-speed transmission for vehicles is more compact, the assembly is simpler, and the power The loss is smaller. As for the composition of the transmission system and the power transmission route determined by the connection sequence between the various p...

The invention discloses a six-gear gearbox for a vehicle and a transmission system thereof. A first clutch and a second clutch of the transmission system are distributed at the rear part of a shell; apower input shaft is connected with a sun gear of a retroaction planetary gear system by the first clutch and connected with a planetary carrier of the retroaction planetary gear system by the secondclutch; the first clutch is also connected with the shell by a second brake; the second brake is positioned at the periphery of the first clutch and shares a hub with the first clutch; a first brakeis positioned at the periphery of an output planetary gear system, and the output planetary gear system is connected with the shell by the first brake; a third brake is positioned at the periphery ofthe retroaction planetary gear system, and the retroaction planetary gear system is connected with the shell by the third brake; and a one-way clutch is positioned at one end of the third brake and also connected with the retroaction planetary gear system. The six-gear gearbox for a vehicle of the transmission system has more compact gearbox structure, shorter power transfer path and less power loss due to reasonable arrangement of all gear shift parts.
Description
technical field [0001] The invention belongs to the technical field of automobiles, in particular to a vehicle transmission, in particular to a transmission system of a six-speed transmission for a vehicle, and a six-speed transmission for a vehicle including the transmission system. Background technique [0002] The speed change mechanism of the vehicle gearbox is composed of multiple planetary gear trains, which receive the speed and torque transmitted from the hydraulic torque converter, and transmit it to the output shaft after conversion. The more gears of the transmission, the more ideal the speed ratio can be designed, and the vehicle can have better fuel economy and driving performance. Because of this, people have also been studying more gears for vehicle transmissions. [0003] As we all know, in a vehicle transmission, the shift between gears is realized by the structural cooperation of two parts, one part is a transmission mechanism composed of multiple planetar...
