Problems solved by technology

This speed change mechanism has the following disadvantages: Since the two wet-type off-stage devices are combined and fixed on the input shaft, although the axial dimension is shortened to a certain extent, due to the use of a mechanical shift synchronizer, the axial length is shortened while the axial length is shortened. A three-axis transmission system has been formed, and the radial dimension increases greatly. This structure makes the structure of the transmission more complicated. At the same time, the combined dual clutch has a complex structure and a larger volume, which increases the difficulty of maintenance. This makes the transmission of this transmission more complicated. The size and weight are still large, the structure tends to be complicated, and the price tends to be expensive, so it is not suitable for installation on small cars and economical cars

Abstract

The invention discloses a double-clutch automatic speed changer, which comprises an input shaft, a reverse shifting shaft and a power output device. Two sides of the input shaft are sleeved with two main shafts arranged collinearly with the input shaft respectively, and the input shaft between the two main shafts is provided with a supporting bearing; the two main shafts are provided with clutches, main shaft angle sensors, reverse driving gears and forward odd driving gears in turn; the reverse shifting shaft is connected with a reverse shifting gear which is meshed with the reverse driving gears on the main shafts; the power output device comprises a main power output shaft and an output shaft, one end of the main power output shaft is connected with a main power output shaft angle sensor, and a differential mechanism is connected between the main power output shaft and the output shaft; and the main power output shaft is provided with reverse driven gear and a forward driven gear which is meshed with the forward driving gears arranged on the two main shafts respectively. The double-clutch automatic speed changer has the advantages of small volume, little gear amount, compact structure, light weight and wide power transmission range, and is applicable to automobiles.

Description

technical field [0001] The invention relates to a vehicle transmission, in particular to a dual-clutch automatic transmission without a mechanical synchronizer. Background technique [0002] The existing dual-clutch automatic transmission includes two clutches, a mechanical shift synchronizer, a shift control system, an electronic control system TCU, and a six-speed transmission. Usually, two wet clutches are combined into an integrated dual clutch, which are respectively fixed on On the two main shafts, the driving gears of the odd and even gears of the transmission are respectively driven and connected with two wet clutches. The two clutches alternately transmit working power to realize switching between gears. This speed change mechanism has the following disadvantages: Since the two wet-type off-stage devices are combined and fixed on the input shaft, although the axial dimension is shortened to a certain extent, due to the use of a mechanical shift synchronizer, the ax...
