Problems solved by technology

At present, the existing dual-clutch automatic transmission generally adopts a parallel-shaft gear structure. The structure of the automatic transmission with this structure is not compact enough, and there are many actuators, and the actuators change during gear shifting, which is easy to cause motion interference.

Abstract

The invention discloses a single-stage and double-stage planet gear combined type six-gear automatic transmission. The single-stage and double-stage planet gear combined type six-gear automatic transmission comprises a front-row single-stage planet gear mechanism composed of a front-row planet carrier (6), a front-row planet gear (7), a front-row sun gear and a front-row gear ring, a middle-row double-stage planet gear mechanism composed of a middle-row planet carrier (13), a middle-row first planet gear (11), a middle-row second planet gear (10), a middle-row sun gear and a middle-row gear ring, and a rear-row single-stage planet gear mechanism composed of a rear-row planet carrier (15), a rear-row planet gear (17), a rear-row sun gear (16) and a rear-row gear ring (18). The automatic transmission has the beneficial effects of being simple and compact in structure, few in machining part type, low in cost, few in executing component, little in executing component transformation during gear shifting and not prone to movement interference.

Description

technical field [0001] The invention relates to a single and double-stage planetary gear combined six-speed automatic transmission. Background technique [0002] An automatic transmission mainly includes a planetary gear unit, clutches and brakes. The automatic transmission uses automatic transmission oil for energy conversion and power transmission, and uses oil pumps, oil circuits, clutches, planetary gear sets, multiple solenoid valves and other components to realize automatic transmission, bringing easy and simple driving experience to people's car driving . [0003] And existing double-clutch automatic transmission has two power input clutches, and wherein a clutch is responsible for the power input of odd-numbered gears, and another clutch is responsible for the power input of even-numbered gears, and it has the advantages of smooth shifting, good comfort, and fuel economy. At present, the existing dual-clutch automatic transmission generally adopts a parallel-shaft ...
