Drive Shaft

Wheel Drive Shafts Description and Operation
Wheel drive shafts are flexible assemblies consisting of an inner tripot joint and an outer constant velocity joint
connected by an axle shaft. The inner joint is completely flexible, and can plunge in and out. The outer joint is also
flexible, but cannot plunge in and out. These drive axles are used to transmit rotational force from the transaxle to the
front tire and wheel assemblies.
Seal and Clamp
The wheel drive shafts use inboard and outboard joint seals made of thermoplastic material, and clamps made of
stainless steel. The functions of the seals are as follows:
• The seals protect the internal parts of the inboard and outboard joints.
– They protect the joint lubricating grease from surrounding detrimental atmospheric conditions; such as extreme
temperatures, ozone gas, etc.
– They protect the joint lubricating grease from foreign materials; such as stones, dirt, water, salt, etc.
• The seals facilitate angular and axial movement of the inboard joint.
• The seals facilitate angular movement of the outboard joint.
The function of the clamps is as follows:
Provide a leak proof connection at both the housing and the axle shaft for the inboard and outboard joints.
The thermoplastic material performs well against normal handing, operational wear and conditions. This material
however, is not strong enough to withstand abusive handling or damage due to objects such as sharp tools or the
sharp edge of any other surrounding component on the vehicle.
Inner Joint
The inner joints are of the tripot design without an over-extension limitation retainer. The inner joints incorporate a
male spline which interlocks with the transaxle using snap rings.
Outer Joint
The outer joints are of the Rzeppa, constant velocity joint design. The shaft end which mates with the wheel bearing
and hub assembly, incorporates a helical spline to assure a tight, press-type fit. This design assures that no end play
will exist between the hub bearing and the drive shaft assembly for added durability and reduced bearing noise.
