Technical field
The utility model relates to a kind of fixture, in particular to a kind of reverse gear synchronizer ring gear pressing clamp.
Background technique
Since transmission input shaft and output shaft are rotated with respective speed, there are one " synchronizations " to ask for conjunction when converting gear
Topic.Two different gears of rotation speed engage by force will necessarily occur impact, damage gear.Therefore, old-fashioned speed changer
Shift will be by the way of " bipod clutch ", upshift stops a moment in neutral gear position, downshift will in neutral gear position open out, with
Reduce the rotational speed difference of gear.But this operation is more complicated, it is difficult to grasp accurate.Therefore designer creates " synchronizer ", leads to
Crossing synchronizer makes that meshed gears will be wanted to reach consistent revolving speed and smoothly engage.
The component of reverse gear synchronizer includes tooth set, and tooth set is annular in shape, and tooth further includes ring gear on inner wall, and ring gear passes through pressure
