特殊结构的驱动桥试验台

A Specially Constructed Test Bench for Driving Axle

介绍了一种特殊结构的驱动桥试验台。这种试验台由一个主试桥同时带动两个陪试桥,使陪试桥的扭矩降低到主试桥的一半,而转速与主试桥相同。这种试验台能使陪试桥齿轮的寿命大大延长。介绍了试验台传动系统的结构和试验方法。

A specially constructed test bench for driving exle is introduced.Two assistant axles,instead of one,are simultaneously driven by a main tested axle,thereforathe torque in each assistant axle is reduced to a half as in the main axle,white their speed are the same.In such a way,the operation durability of assistant axles can be greatly increased.The construction of driving system of the test bench and the testing procedure are presented.
