Longitudinal dual clutch automatic transmission device with direct gear

Abstract

The invention relates to a longitudinal dual clutch automatic transmission device with a direct gear. The device comprises a first clutch, a second clutch, and two input shafts which are fixedly connected with the clutches and are coaxial to each other, wherein a first input shaft gear is arranged on the first input shaft; a fifth synchronizer and an output shaft are arranged at an outward extending end of the first input shaft; a first reverse gear driven gear, a second and third gear driven gear and a fourth and fifth gear driven gear are arranged on the output shaft in sequence; a first intermediate shaft, a second intermediate shaft and a reverse gear shaft are respectively parallel to the output shaft; a first intermediate shaft gear, a fourth gear driving gear, a third synchronizer, a first synchronizer, a second gear driving gear and a reverse gear driving gear are arranged on the first intermediate shaft in sequence; a second intermediate shaft gear, a fifth gear driving gear, a fourth synchronizer, a second synchronizer, a third gear driving gear and a first gear driving gear are arranged on the second intermediate shaft in sequence; and a reverse gear intermediate gear is arranged on the reverse gear shaft. The longitudinal dual clutch automatic transmission device comprises the direct gear and has high transmission efficiency; and a gear is shared by a plurality of gears, and the axial length is short.

Description

technical field [0001] The invention belongs to the technical field of automatic transmissions, and in particular relates to a double-clutch automatic transmission transmission device. Background technique [0002] The dual-clutch automatic transmission transmission system refers to the power transmission system composed of clutches, gear transmissions, synchronizers, etc. that the transmission path of the dual-clutch transmission passes through. The dual-clutch automatic transmission has two independently controllable clutches, and the two clutches are respectively connected to the corresponding input shafts. The engine power can be transmitted to the input shafts by any clutch, and provides power to the vehicle through the transmission system. The odd and even gear input gears of the transmission are arranged separately on two shafts. Through the switching of the two clutches and the action of the synchronizer, the torque conversion and output are realized through differen...

Problems solved by technology

In a traditional dual-clutch automatic transmission, usually each gear requires a pair of gear pairs to complete the power transmission work. Therefore, when the transmission has many gears, the number of gears required is large, and the transmission is heavy, bulky, and expensive to manufacture. High, which is not conducive to the layout of the vehicle and the performance of vehicle power and fuel economy; the length of the hollow outer input shaft of the longitudinal dual-clutch automatic transmission is long, and the processing is extremely difficult; at the same time, most traditional dual-clutch automatic transmissions do not have direct gears. Each gear uses gear pair meshing to transmit power, the transmission efficiency is relatively low, and the noise is large
