【摘要】 一种由于输入转速和输出扭矩的变化而无级变速的V带传动,已成功的在极地雪橇车和小型汽车的变速器中得到了应用。这种变速器的普遍应用和具有的可靠性,发展了它的设计。本文介绍了摩托车上常用的V型皮带式无级变速器的工作原理。通过对V型皮带式无级变速器主动轮和从动轮的力学分析,建立了皮带传动的力学关系式,推导了这种传动的设计公式,并指出了现有公式的不足。更多还原

【Abstract】 A type of V-belt drive which shifts ratios in accordance with input speed and output torque has been successfully employed as the transmission for vehicles ranging from snowmobiles to compact automobile. Increasing popularity of this kind of transmission has created the need for more reliable criteria to be used in its design; The operation principle of V-belt continuously variable transmissions equipped on motorcycles is presented .On the basis of force analysis of the driving clutch and the driven clutch ,and has set up the mechanical equation of belt transmission. this paper presents a derivation of design equations,the fault of present calculation formula has been pointed out.更多还原
