The power conversion device comprises a reverse gear transition component, a power input mechanism and a power output mechanism, wherein the power output mechanism is connected with the power input mechanism in a sliding and sleeving mode; an engagement structure is arranged between the power input mechanism and the power output mechanism; the power input mechanism is further provided with a first inclined fluted disc; the power output mechanism is further provided with a second inclined fluted disc; and the reverse gear transition component is matched with the first inclined fluted disc and the second inclined fluted disc. According to the power conversion device, coaxial locking operation of a forward gear is achieved, a planetary gear which is large in size and high in energy loss and a complex variable speed control system are omitted, and the power conversion device has the remarkable advantages that coaxial locking operation of the forward gear is achieved, a reverse gear is powerful, stable and reliable, gear shifting is smooth, the size is small, energy loss is low, and maintenance is convenient.

Description

technical field [0001] The invention relates to a power conversion device, in particular to a power conversion device of a shifting mechanism. Background technique [0002] Existing mechanical automatic transmissions include two categories: the first type is a stepped automatic transmission, which realizes the purpose of automatic transmission through the automatic control of the automatic control system, such as AMT, AT, DCT, etc.; the second type is a continuously variable automatic transmission, such as CVT. Both of the above two automatic transmissions need to be equipped with complex automatic control systems and mechanical transmission systems. The stepped automatic transmission has a longer history and is used the most. The consumption is slightly insufficient. [0003] The shifting mechanism of the continuously variable automatic transmission, as an auxiliary mechanism of the continuously variable automatic transmission, is used in various vehicles, construction ma...

Problems solved by technology

[0005] (2) The entire shifting mechanism is large in size and high in energy loss: the large size of the planetary gear set is the root cause of the large size of the entire shifting mechanism, and the driving of the large-volume planetary gear set will consume more power when it starts, stops, and runs. energy of;

[0006] (3) In the case of the same input torque, the output torque of forward gear and reverse gear is also the same, resulting in the phenomenon that the CVT reverse gear is weak
