Automobile dual-clutch automatic transmission

Abstract

The embodiment of the invention discloses an automobile dual-clutch automatic transmission. A first input shaft is distributed to a first clutch. A second input shaft is distributed to a second clutch. The first input shaft is responsible for the input of a first gear, a third gear and a fifth gear. The second input shaft is responsible for the input of a second gear, a fourth gear, a sixth gear and a reversing gear. A first gear driving gear and a third and fifth gear driving gear are arranged on the first input shaft. A second gear driving gear and a fourth and sixth gear driving gear are arranged on the second input shaft. A first gear driven gear and a second gear driven gear are distributed on different output shafts. The second gear driven gear is also used as a reverse middle idle gear for the reversing gear and is aligned to the second gear driving gear and the reversing gear driven gear. A third gear driven gear and a fifth gear driven gear are distributed on different output shafts, are aligned to each other and share the third and fifth gear driving gear. A fourth gear driven gear and a six gear driven gear are distributed on different output shafts, are aligned to each other and share the fourth and sixth gear driving gear. A parking ratchet is arranged on an output shaft on which the first gear is arranged.

Description

technical field [0001] The invention relates to the technical field of stepped automatic transmissions for automobiles, in particular to an automatic double-clutch transmission for automobiles. Background technique [0002] Since the beginning of this century, wet-type and dry-type dual-clutch automatic transmissions have been put into the market successively with complete vehicles, gradually occupying an important market share, and major foreign powertrain companies have also produced other mass-produced models and models with more efficient internal configuration combinations. With the mass production capacity of external interface supply, dual-clutch automatic transmission has become the mainstream of research and development recognized and carried out by major domestic and foreign car companies. At present, the focus of development and competition in the market is whether it can be more efficient, more compact, more economical and more reliable. [0003] Since the radia...

Problems solved by technology

[0003] Since the radial and axial dimensions of the dry dual clutch are very large, it is far from being able to be treated the same as when it is used with an ordinary clutch or a wet dual clutch. In addition, the additional axial space occupied by the hydraulic or electric actuator of the dry dual clutch, and the extra radial space that the dual-mass flywheel may occupy, so that in the early stage of the original conventional vehicle chassis platform series, when the powertrain assembly is arranged, it will inevitably result in the configuration of the dry dual-clutch automatic transmission, which must be carried out on the chassis platform. Make major changes or simply develop a new platform. Without large-scale changes, you cannot configure a dry dual-clutch automatic transmission.
