Problems solved by technology

Due to the different modulus of gears in different gears, the tooth surface contact fatigue bearing capacity, tooth surface bonding bearing capacity, tooth root bending fatigue bearing capacity and other parameters of gears in different gears also change, which can better correspond to actual driving. The impact on gears caused by changes in road conditions and engine operating conditions solves the problems of pitting, broken teeth, and gluing of transmission gears, and at the same time eliminates the noise caused by the above problems, improving the reliability of motorcycles and comfort

Embodiment Construction

[0006] The specific structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0007] see figure 1 , a variable mode transmission mechanism of the present invention, including a main shaft assembly 1 and a countershaft assembly 2, the key of which is to select different gear modules for gears of different gears to meet the requirements of different working conditions. In this embodiment: the first gear m=1.75, the second, third and fourth gears m=2, and the fifth gear m=1.5. The gear modulus is large, and the second, third, and fourth gears correspond to greater loads when the motorcycle is climbing, so the selected gear modulus is also large. The fifth gear corresponds to the flat road with the smallest load when driving at high speed, so the selected gears The modulus is the smallest. Since different gears use different modulus, each gear corresponds to the change of working conditions under normal driving, which sol...

Abstract

Changed module drive device includes main shaft subassembly and counter shaft subassembly. The key points of this invention are: selecting different module of gear for gears in different shift positions to meet the requirements of different operating modes. Because gears in different shift position have different module, then tooth surface contact fatigue, tooth surface glue, and tooth root flexural fatigue bearing capacity etc. of gears in different shift positions are changed, so, they are better to correspond to the changed road condition in the real running and the impact of change of engine operating mode on gear tooth, solve the problems of corrosive pitting, breaktooth, glue of drive gear, at the same time, eliminate the motion noise led by above problems, enhance the reliability and comfortability of a motorcycle.

Description

Technical field [0001] The invention relates to a reduction mechanism, in particular to a variable-mode transmission mechanism which can change the modulus of the transmission gear of the ordinary transmission reduction mechanism and use different modulus for the transmission gears of different gears to meet the changes of various working conditions. Background technique [0002] At present, in the field of mechanical transmission, especially in the motorcycle industry, the transmission reduction mechanism of the engine usually has the same modulus for different gears on the main and auxiliary shafts. In the actual driving process of the motorcycle, different gears have to deal with different road conditions and engine working conditions. For example, when a finished car starts, it generally corresponds to gear 1, gears 2, 3, and 4 are generally used when climbing a slope, and gear 5 is used when driving at high speed on flat roads. In this way, the existing gears with the ...
