Transmission Driveshaft & CV joints from Shaftec

Examining Shaftec’s transmission programme for 2015.

 

Shaftec’s transmission programme focuses on the products that are prone to high failure rates and in high demand in the aftermarket. Shaftec offers new CVJs and a recently introduced CV boots, with a focus on remanufacturing for their driveshaft product range.

As the range of driveshaft and CVJs is ever-increasing, factors will only typically stock the most popular applications due to their cost and size. 

Transmission Basics

The driveshaft is the link between the engine and the wheels and is made up of an inner and outer joint along with a connecting shaft. Its function is to transmit the engines rotational power (i.e. torque) to the wheels.

The CVJ allows the driveshaft to drive the wheels of the vehicle through all degrees and at a constant velocity.  This is made possible through the use of ball bearings running in a ‘race’.

The CVJ consists of the following:

Outer CVJ: allows the driveshaft to transmit the engine’s rotational power through a variable angle and at a constant velocity.

Inner CVJ: is the direct link between the transmission and the drive shaft. The inner CVJ turns with the rotation of the engine and spins the driveshaft with it.

Inner and Outer CV Boots – These protect the CVJs by keeping dirt and water out and reducing the chance of salt entering the system which can otherwise cause corrosion to the internal components and ultimately lead to their premature failure. The inner and outer CV boots also act as a means to seal essential lubrication in.

Increased Demand in the winter months

Driveshafts and CVJs come under increased pressure during the winter months. If the boots on the CVJs split, water ingress and salt can corrode the internals of the joint. The combination of poor quality of some UK roads and extremely wet winter conditions results in an increased demand for these parts in the aftermarket in the first quarter of the year.

 

Other issues that can go wrong with a driveshaft or a CVJ are:

  • Wear in ball bearings in CVJ.
  • Wear on spline of the driveshaft.
  • CV boot not fitted correctly.
  • Wear on outer and inner race of the CVJ.
  • Lack of maintenance – not regularly lubricated.
  • Fitting damage (spline, thread, inner and outer race).
