Definitions

  • the present invention relates generally to motor vehicle shaft joints, and more particularly concerns a rolling radial boot for a direct torque flow constant velocity joint.
  • Constant velocity joints connecting shafts to drive units are common components in automotive vehicles.

  • the drive unit is an axle, transfer case, transmission, power take-off unit or other torque device, all of which are common components in automotive vehicles.
  • one or more joints are assembled to the shaft to form a propeller or drive shaft assembly. It is the propeller shaft assembly, which is connected, for instance, at one end to the output shaft of a transmission and, at the other end, to the input shaft of a differential.
  • the shaft is solid or tubular with ends adapted to attach the shaft to an inner race of the joint thereby allowing an outer race connection to a drive unit.

Flexing also occurs for each rotation of the roll boot due to gravitational and centripetal forces.
  • the flexing action may increase material decay caused by mechanical, chemical and thermal attack related to the environment in which the boot is used.
