Background
The transmission of the commercial vehicle usually adopts a three-shaft structure with an input shaft and an output shaft on the same axis, and the output end is connected with a drive axle through a transmission shaft and then output to wheels on two sides. The passenger car transmission mostly adopts a structure that an input shaft and an output shaft are parallel, the differential is integrated in the transmission, and two sides of the differential are connected with the driving half shafts and then output to wheels on two sides. When the synchronizer is subjected to relevant verification tests, the running speed of a real vehicle is simulated mostly in a mode of driving by the output end of a transmission, the synchronizer testing device of the commercial vehicle only has one output end, and the synchronizer testing device of the passenger vehicle needs two output ends. From the above requirements, it can be seen that the test apparatus of the quotient-by-two synchronizer is not universal. If a passenger car product is verified by using the synchronizer device of the commercial car, a sample needs to be damaged, and a differential half shaft gear and a planetary gear of a passenger car transmission are welded to realize unilateral output. It is undesirable to destroy the sample first when performing bench tests, especially for those very important standards. And newly purchasing or building resources such as funds, fields and the like required by the passenger car test device.
