Embodiment Construction

[0026] 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 creative efforts fall within the protection scope of the present invention.

[0027] An embodiment of the present invention provides an automatic transmission, such as figure 2 As shown, it includes a first input shaft 12, a first planetary gear mechanism 13, and a gearbox housing 17, and the planetary gear mechanism 13 includes: a first main sun gear 131, a first secondary sun gear 132, a first short planetary gear 133 , the first long planetary gear 134, the first planetary carrier 135, the first ring gear 136 and the first constant meshi...

Abstract

The embodiment of the invention discloses an automatic transmission and a vehicle applying the same, relating to the technical field of vehicle fittings and solving a problem that the vehicle has poor gear-shifting smoothness and low power performance when a traditional four-gear transmission is used. The automatic transmission disclosed by the invention comprises a second input shaft, a second planetary gear mechanism and a second transmission mechanism, wherein the second transmission mechanism is properly selected to operate when the second input shaft acts, so that a second planetary gear forms transmission ratio of four advance powers; the second input shaft is matched with the first input shaft, so that a first planetary gear and the second planetary gear jointly form transmission ratio of eight advance powers, the gears of the vehicle are increased, and a speed ratio of the gears is reduced; moreover, the first input shaft and the second input shaft operate independently, when one input shaft operates, the other input shaft can achieve pre-shifting, thereby reducing the gear-shifting time and improving the gear-shifting smoothness; simultaneously, the requirements of the vehicle under different powers are satisfied, thereby greatly bringing the vehicle dynamic performance into effect furthest, and improving the dynamic performance and economic performance of the vehicle.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an automatic transmission and an automobile using the same. Background technique [0002] Cars equipped with automatic transmissions have the advantages of high comfort, convenient operation, and good fuel economy. Therefore, many domestic automakers are making continuous efforts to independently develop cars with automatic transmissions. Among them, four-speed automatic transmissions or five-speed automatic transmissions Most of the transmissions. [0003] In a car equipped with an automatic transmission, the torque converter is generally driven by the engine, and the power of the torque converter is then transmitted to the differential through the transmission to complete the power output. Such as figure 1 As shown, the four-speed automatic transmission includes: an input gear 11, an input shaft 12, a planetary gear mechanism 13, a speed change mechanism 14, an intermediat...
