Problems solved by technology

The power of this structure is transmitted through the intersecting bevel gears, and the power loss is relatively large. In particular, the fork mechanism and the bevel gears use keys or keyways to cooperate, and the reverse gear must be switched in the parking state.

Embodiment Construction

[0010] see figure 1 , The circumference of the spline sleeve 2 is provided with transmission teeth, the transmission teeth and the spline sleeve 2 are an integral part, and the internal teeth of the synchronous ring 7 mesh with the transmission teeth of the spline sleeve 2. The reverse gear 4 and the output gear sleeve 3 are respectively vacantly sleeved on the spline sleeve 2 on both sides of the transmission gear. Both the reverse gear 4 and the output gear sleeve 3 are integral duplex cylindrical teeth, and their combined teeth are adjacent to the drive teeth of the spline sleeve 2, and have the same number of teeth and the same modulus as the drive teeth. The coupling teeth of the reverse gear 4 and the output gear sleeve 3 and the internal teeth of the synchronizing ring 7 are all triangular teeth, so that the synchronizing ring 7 and the coupling teeth can be meshed conveniently and freely without interference. One end of the spline sleeve 2 is transitionally fitted wit...

Abstract

A reverse unit installed to the secondary shaft of speed variator for motor-cycle is disclosed. A shift for assembly sleeves on a slide axle. Its fork is connected to cynchronizing ring engaged with the drive teeth of splined sleeve. The reverse gear and output toothed sleeve respectively sleeve on the splined sleeve at both sides of its drive teeth. The reverse gear is engaged with a connecting gear A. The output toothed sleeve is engaged with another connecting gear B. A is locally engaged with B. The splined sleeve is linked to the spline of said secondary shaft of speed variator.

Description

technical field [0001] The invention relates to a motorcycle reverse gear, in particular to an external reverse gear for three-wheeled and four-wheeled motorcycles. Background technique [0002] At present, three and four-wheel motorcycles use reverse gears, and more adopt driving gears on the secondary shaft of the engine transmission, and install a forward gear driven bevel gear and a reverse gear driven bevel gear on the output shaft of the reverse gear. It is oppositely meshed with the driving gear, and its output shaft is perpendicular to the secondary shaft of the transmission. By moving the connecting sleeve on the output shaft, it is connected with the driven bevel gear for forward gear or the driven bevel gear for reverse gear, so that the direction of rotation of the output shaft forms a clockwise rotation or Reverse, so as to realize the conversion of forward gear or reverse gear. For example, Chinese patents ZL01227818.1, ZL98201747.2, 02221957.9, and 00106301.4...
