Abstract
The utility model discloses a reverse gear shifting structure. Internal splines are arranged on the inner wall of a slide sleeve, ring grooves are formed on the outer wall of the slide sleeve, external splines which can be matched with the internal splines of the slide sleeve are arranged on a reverse gear, internal splines and external splines which can be matched with the internal splines of the slide sleeve are arranged on a reverse gear clutch body, and the slide sleeve can move relative to the reverse gear and the reverse gear clutch body in the axial direction. When all the internal splines of the slide sleeve are completely separated from the external splines of the reserve gear and are meshed with the external splines of the reverse gear clutch body, reverse gear take-off is achieved. When one part of the internal splines of the slide sleeve are meshed with the external splines of the reverse gear clutch body, and the other part of the internal splines of the slide sleeve are meshed with the external splines of the reverse gear, reverse gear engaging is achieved. Gear engaging can be achieved easily with no internal splines with helical angles are machined on the slide sleeve of the structure. Therefore, slide sleeve is simple in machining, rejection rate is reduced, and manufacturing cost of the reverse gear shifting structure is correspondingly reduced. The utility model further discloses a transmission with the reverse gear shifting structure and a car.
