【摘要】：基于汽车分时驱动和全时驱动整车动力性能要求,研究了分动箱链传动的匹配计算,分析了分动箱在各种典型工况下,其分动箱链条所承受载荷的计算方法,并据此提出安全匹配设计方法。介绍了分动箱链传动的试验方法并分析了试验结果,列举了分动箱选择匹配设计实例。结果表明,汽车分动箱链条的匹配设计在满足汽车分动箱动力分配的前提条件下,可以充分保证链传动系统的疲劳性能和磨损性能,该方法对汽车领域四驱分动箱链传动系统的自主开发具有重要的指导意义。
[Abstract]:Based on the dynamic performance requirements of the vehicle with time-sharing drive and full-time driving, the matching calculation of the chain drive of the shunting box is studied, and the calculation method of the load of the shunting box chain under various typical working conditions is analyzed. According to this, the design method of safety matching is put forward. The test method of chain drive of shunt box is introduced, and the test results are analyzed, and an example of selecting matching design of shunt box is given. The result shows that. The matching design of automobile shunt box chain can fully guarantee the fatigue and wear performance of the chain transmission system under the precondition of satisfying the power distribution of the automobile shunting box. This method has important guiding significance for the independent development of the chain drive system of four-drive split-box in automobile field.
