Rear axle reverse gear mechanism for four-wheel motorcycle

Abstract

The invention discloses a rear axle reversing gear of four-wheeled motorcycle, a trailing axle of a motorcycle runs through the shaft hole on both ends of shell, respectively positioning assembled with driving-driven bevel gears by a bearing, the driving-driven bevel gears are toothed with the inertia bevel gear respectively, and driving-driven bevel gears are equal-clearance fitted on the trailing axle, and the axle section of the trailing axle between two bevel gears spline matches a synchronizing sleeve that can make axial displacement, and the synchronizing sleeve can spline fit the driving-driven bevel gears by axial displacement, the shift fork is fastened in groove surrounds the excircle of the synchronizing sleeve, the driving bevel gear is spline connected with the chain wheel seat which is in clearance fit with shell and the trailing axle. The invention provides the rear axle of four-wheeled motorcycle, a trailing axle is used to transmit advance or recessional moment of torsion, which makes left and right rear wheel motion harmony unified, and the power transmission is steady, engine structure change is unnecessary, which has commonality, simultaneously, it simplifies structure of the rear axle reverse gear and lowers the cost.

Description

technical field [0001] The invention relates to the field of rear axles of four-wheeled motorcycles, in particular to a rear axle reverse gear mechanism of four-wheeled motorcycles. Background technique [0002] The four-wheeled motorcycle, commonly known as ATV, has a reverse gear mechanism because of its sports performance. One is to set a reverse gear mechanism in the engine transmission, which will change the internal structure of the engine and increase the volume of the engine, resulting in The engine of the four-wheeled motorcycle and other parts associated with the engine all need to be redesigned and molded, which increases the design and production costs. In order not to change the internal structure of the engine, the other is to use an external reverse gear. The reverse gear is installed on the engine case and connected to the output shaft of the engine. The reverse gear is connected to the four-wheel motorcycle through a long shaft. The gearbox of the rear axle...

Problems solved by technology

This reverse gear mechanism is installed in the differential case, the rear wheel output shaft is divided into left and right half shafts, and the transmission gear adopted is a rear axle reverse gear differential with cylindrical spur gears. The disadvantage is that The output shafts of the rear axle are left and right half axles, which makes the movement coordination of the left and right rear wheels poor. A differential must be set to distribute the transmission force, which makes the structure of the r
