Description
(1) technical field
The present invention is a kind of synchronized gear shift structure of automobile, particularly relates to a kind of diff, electrical motor of utilizing and makes hand-operated transmission carry out the structure of syn gear shift.
(2) background technology
Automotive engine is decided to turn round in the range of speed at a weighing apparatus substantially, but automobile need change speed in very big scope, make its reach increase turn round deceleration, become distortion speed and neutral gear, the reversing effect, therefore a change-speed box must be arranged, the structure of conventional manual change-speed box is, on imput shaft and driven shaft, disposed the multiple sets of teeth wheel respectively, on driven shaft, disposed corresponding movable spline housing, pull out gear by manual fork to needs, promote corresponding spline housing and move, make corresponding driven gear and output shaft spline engagement realize gear shift.The hand-operated transmission transmission system has that volume is little, in light weight, simple in structure, cost is low, reliable transmission, driving efficiency advantages of higher, therefore generally believe or traditional hand-operated transmission structure comparatively economical, reliable, practical.
