BOOT UNIT FOR CONSTANT VELOCITY JOINT

摘要

PURPOSE: The deformation due to the pressure gradient and damage is prevented and durability can be improved in the inside heat generation of the constant velocity joint. CONSTITUTION: A boot unit(100) for the constant velocity joint comprises a boot body(110), a curved part(120), and a fixed part(130). The boot body is formed into the cylindrical shape. The boot body comprises the flange part(111) which is inserted in the driven shaft(14) and is touched. Two or more protrusions(113) are formed in phase if it scores of the boot body. The curved part is into one body extended in the other side of the boot body. It is extended from the curved part and the fixed part is fixedly inserted in the joint in which the end part of the housing cap is bent. In protrusion, the shape of the section is formed into circular.
