AI Technical Summary

Problems solved by technology

The transmission shafts of constant velocity universal joints are all equipped with rubber dust jackets. The low temperature resistance of the rubber materials of the dust jackets of the existing constant velocity universal joint transmission shafts is around -40°C, which cannot meet the lower temperatures in northern my country and Russia. Under the requirements of use, it needs further improvement to improve low temperature resistance

Description

technical field [0001] The invention relates to the technical field of production of rubber products for vehicles, in particular to a low temperature resistant dust jacket rubber. Background technique [0002] With the development of the car industry, users have higher and higher requirements for the comfort, power, and maneuverability of cars. The market demand directly promotes the development of FF (front-engine front-wheel drive) and 4WD (four-wheel drive) vehicles. appear. Their front wheels, that is, the driving wheels, can realize both steering and driving functions at the same time, and the front axle drive shaft continuously transmits power from the final drive to the wheels at the same angular velocity during the wheel deflection process. In order to realize this function, a constant velocity universal joint mechanism was developed to connect such two transmission shafts whose axes do not overlap and whose mutual positions change frequently, and transmit motion an...
