Integrated multifunctional power-assisted gearshift mechanism

Abstract

The invention discloses an integrated multifunctional power-assisted gearshift mechanism. A central rotary shaft of the integrated multifunctional power-assisted gearshift mechanism is provided with arotary shaft body and a cam installed on the rotary shaft body; a gearshift module comprises an inner gear, a central shell arranged at the middle part of the inner gear, and a plurality of gear assemblies which are slidably nested onto the central shell; the rotary shaft body stretches into an empty cavity of the central shell, the gear assemblies are distributed around the rotary shaft body, and the whole assembly structure is simple and compact, so that realization for miniaturization production is benefited; the cam is capable of being abutted against one end of any gear assembly while rotating, the gear assembly is ejected to the other end to be connected with the inner gear, fixing for a gear is realized, and in this way, switchover for the different gears can be realized by virtueof the rotation of the cam, and the gearshift process is flexible and convenient; and moreover, a return component is arranged, the gear assemblies can automatically return to the original positions after separating from the cam, and interference among the different gears can be avoided, so that the accuracy of gear switchover is increased; and the integrated multifunctional power-assisted gearshift mechanism is used in the field of gearshift control machinery.

Description

technical field [0001] The invention relates to the field of gear shifting control machinery, in particular to an integrated multifunctional power-assisted gear shifting mechanism. Background technique [0002] At present, most of the devices for the elderly adopt the mode of manual shifting. During the process of manual shifting, the user needs a lot of force to complete the shifting, which is not conducive to the operation of the sick or the elderly. [0003] In addition, most of the existing gear shifting mechanisms are double-row sliding gear transmission mechanisms, and its parts include dozens of sliding shift forks, spline shafts, positioning steel ball groups, dial pins, rotating shafts, and guide keys; at the same time, In order to control the multi-stage speed change, the mechanism often needs to install multiple rotating shafts, and the gear of the main shaft changes up and down to mesh with the gear of the auxiliary shaft to achieve the effect of speed change.
