Double-overrunning-clutch shaft sleeve output taper sleeve type self-adaptive automatic gear shifting spindle assembly

Abstract

The invention discloses a double-overrunning-clutch shaft sleeve output taper sleeve type self-adaptive automatic gear shifting spindle assembly. The double-overrunning-clutch shaft sleeve output taper sleeve type self-adaptive automatic gear shifting spindle assembly comprises a spindle, a gear shifting system and a power output shaft sleeve, wherein the gear shifting system and the power outputshaft sleeve are arranged on the spindle. The gear shifting system comprises a low speed gear power input member, a reverse gear power input member and a self-adaptive gear shifting assembly; the reverse gear power input member has a transmission ratio I, the low speed gear power input member has a transmission ratio II, and the transmission ratio I is greater than or equal to the transmission ratio II; the double-overrunning-clutch shaft sleeve output taper sleeve type self-adaptive automatic gear shifting spindle assembly utilizes reasonable matching of two overrunning clutches, a reverse gear structure and a low speed gear mechanism reasonably set the transmission ratios, so that the overall structure is simple and compact, no interference occurs, the overall performance is ensured, thestability of the transmission is ensured, the shaft sleeve is used for outputting power, the output parts can be selected according to needs, and the double-overrunning-clutch shaft sleeve output taper sleeve type self-adaptive automatic gear shifting spindle assembly is not only suitable for the field of electric vehicles, but also suitable for other fields of variable torque mechanical transmission; and meanwhile, the shaft sleeve output can further ensure larger output torque.

Description

technical field [0001] The invention relates to a motor vehicle transmission, in particular to a dual overrunning clutch sleeve output taper sleeve type self-adaptive automatic transmission main shaft assembly. Background technique [0002] The working conditions of mechanical transmission systems are generally complex, and torque needs to be distributed to realize the transmission of different loads and speeds. Taking electric vehicles as an example, the driving environment is complex and changeable. Moreover, the electric drive method commonly used in existing electric vehicles is a motor-driven fixed-speed ratio, and the reasonable range of high efficiency is narrow and limited, resulting in a vicious circle, resulting in the following problems: [0003] 1. It can only work within the torque range of a certain working condition. [0004] 2. In order to meet the road conditions under the condition of constant speed ratio, the speed of the motor can only be increased, whic...
