Abstract

The invention discloses a slide-way-type meshing device and a gear shifting device and further discloses a transmission comprising the gear shifting device. When meshing is needed, the rotating speedof a driven meshing gear is adjusted while a driving meshing gear is axially pushed; through the buffer, limiting and guiding effects of an inclined slide way on a limiting device, phase synchronization of the rotating speeds and rotating angles of the driving meshing gear and the driven meshing gear is stably achieved; when the limiting device slides along the inclined slide way to the gear groove end of the inclined slide way, the driving meshing gear fully meshes with the driven meshing gear; and the limiting device and the slide way are arranged for meshing guiding, and precise positioningbetween the driving meshing gear and the driven meshing gear is achieved so that a control motor can be only used for achieving rotating speed synchronization without precise rotating angle phase synchronization, and therefore, the precision requirement for the control motor is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle gear shifting, in particular to a slideway type engagement device and a gear shifting device. In addition, the present invention also relates to a transmission comprising the above-mentioned shifting device. Background technique [0002] A pure electric vehicle refers to a vehicle powered by an on-board power supply and uses a motor to drive the wheels. A hybrid vehicle refers to a vehicle with more than two power sources. Its appearance is between traditional vehicles and pure electric vehicles. Due to its impact on the environment Compared with traditional cars, it is relatively small, and its prospects are widely viewed. [0003] Compared with traditional cars, pure electric vehicles and hybrid vehicles not only have the advantages of energy saving and environmental protection, but also have the characteristics of constant torque at low speed and constant power at high speed, which are more in...
