Problems solved by technology

Since the above-mentioned gearbox realizes the reduction transmission between the input shaft and the output shaft through only one auxiliary shaft, the gear sets of all gears are arranged linearly and sequentially on the first input shaft and the second input shaft, and its output The shaft and the input shaft are located on the same axis to form a series arrangement, so that the length of the entire gearbox case is longer, and it is difficult to meet the shifting needs of vehicles with front transverse front drive

Abstract

The invention discloses a double clutch type automatic gearbox, which comprises a shell of the gearbox, first and second input shafts, and first and second automatic clutches which selectively transmit the rotation of a motor to the first or second input shaft; two sides of the first and second input shafts are provided with first and second output shafts basically parallel to the first and second input shafts; driving gears arranged on the input shafts are meshed with driven gears capable of rotatably sleeved on the first output shaft and / or the second output shaft; and at least one driving gear in the driving gears arranged on the first input shaft or the second input shaft is simultaneously two driven gears on the first and second output shafts. The driving gears are shared, so the arrangement mode of the gear transmission group is changed into a parallel arrangement mode, the length of the gearbox can be greatly shortened, the gearbox can be provided with eight gears on the premise of maintaining the same dimension as a five- or six-gear gearbox, and the dynamic property, the economical efficiency and the grade of the whole vehicle are obviously improved.

Description

technical field [0001] The invention relates to a transmission for a vehicle, in particular to a double-clutch automatic transmission for a front-transverse front-drive car. Background technique [0002] At present, the three main types of automatic transmissions used in automobiles are divided into hydraulic automatic transmission AT (Automatic Transmission) composed of hydraulic torque converter, planetary gear mechanism and electro-hydraulic control system, traditional fixed shaft transmission and dry transmission. The electro-mechanical automatic transmission AMT (Automated Manual Transmission) and the continuously variable automatic transmission CVT (Continuously Variable Transmission) are composed of the clutch and the corresponding electro-hydraulic control system. [0003] The hydraulic automatic transmission AT has the advantages of stable start, rapid acceleration, uniformity and softness. It is the leading product of vehicle automatic transmission at present, but ...
