Damping hydraulic clutch planetary gear automatic transmission and gear shifting method thereof

Abstract

The invention relates to a damping hydraulic clutch planetary gear automatic transmission and a gear shifting method thereof, and belongs to the technical field of transmissions. The damping hydraulicclutch planetary gear automatic transmission specifically comprises an input shaft and an output shaft which are installed in a transmission shell, a plurality of low-speed gear mechanisms, a plurality of high-speed gear mechanisms and a reverse gear mechanism are installed on the input shaft, a plurality of first speed regulating gears which are correspondingly meshed with the low-speed gear mechanisms, the high-speed gear mechanisms and the reverse gear mechanisms are installed on the output shaft, an electronic synchronizer is arranged between the first speed regulating gears and the output shaft. The damping hydraulic clutch planetary gear automatic transmission and the gear shifting method thereof are reasonable in structural design, good in stability and long in service life, and power transmission does not need a friction piece.

Description

technical field [0001] The invention relates to a damping hydraulic clutch planetary gear automatic transmission and a shifting method thereof, belonging to the technical field of transmissions. Background technique [0002] There are gearboxes configured for all power output variable speed transmission systems including domestic and foreign vehicles. The transmission structure, manufacturing process and service conditions of the vehicle configuration are the most complex. Taking the automatic or manual automatic integrated gearboxes with 4 to 6 gears as an example, they all have the defects of complex structure, high manufacturing cost, large volume, difficult maintenance and high energy consumption. Although the existing manual gearboxes are relatively simple in structure, low in manufacturing cost, small in size, light in weight, easy in maintenance and low in energy consumption, they are likely to cause driver fatigue. These defects of existing gearboxes are mainly due...

Taking the automatic or manual automatic integrated gearboxes with 4 to 6 gears as an example, they all have the defects of complex structure, high manufacturing cost, large volume, difficult maintenance and high energy consumption

Although the existing manual gearboxes are relatively simple in structure, low in manufacturing cost, small in size, light in weight, easy in maintenance, and low in energy consumption, they are likely to cause driver fatigue

These defects of the existing gearboxes are mainly due to the single function of the traditional clutch, which has different defects.

For example, the traditional overrunning clutch can neither fix the speed nor control itself; the friction clutch has a complex structure, and requires a large external squeezing force perpendicular to the friction direction when engaging; the jaw clutch can only operate at extremely low speed or at rest. Engaged under the state, and the impact force cannot be avoided; at the same time, due to the existence of the friction plate, the stability of the gearbox is poor, which also affects the short service life
