CARDAN REPAIR AND REPLACEMENT

The driveshaft, commonly known as the cardan, is a mechanical device used to transmit torque from the gearbox to the drive wheels of a vehicle, especially in vehicles with rear-wheel or all-wheel drive. It consists of s
everal key elements, such as universal joints, bearings, and couplings, which provide flexibility and allow it to operate under various conditions.

Main Functions and Structure of the Driveshaft:
  1. Torque Transmission: The driveshaft transmits rotational motion from the gearbox to the rear differential (in the case of rear-wheel drive) or to both front and rear differentials (in the case of all-wheel drive).
  2. Compensation for Angle and Length Changes: Since the axle and gearbox are at different heights and can shift relative to each other (especially when driving over rough terrain), the driveshaft must be flexible. This flexibility is provided by the universal joints and spline connections.
Driveshaft Installation:
  1. Preparing the Vehicle: Before installing the driveshaft, the vehicle is lifted on a hoist, ensuring easy access to the underside and the gearbox.
  2. Removing the Old Driveshaft (if necessary): Using wrenches and other tools, the old shaft is dismantled, and the bolts securing the universal joints and coupling are removed.
  3. Installing the New Driveshaft:
    • The new shaft is lifted into place.
    • The shaft is secured with fastening elements on the splines and universal joints.
    • Special attention is given to the torque of the bolts to ensure secure fastening and prevent vibrations.
  4. Balancing and Testing: After installation, the shaft is checked for balance. If the balance is off, adjustments are made to eliminate vibrations during movement. A test drive is then conducted to verify the operation.
Driveshaft Usage:

The driveshaft is used in vehicles to transmit torque over distances where a simple connection of shafts is impossible due to changes in angle and length. This is especially relevant for vehicles with high ground clearance or off-road vehicles.

Types of Services Related to the Driveshaft:
  • Driveshaft Diagnostics and Repair: Includes checking for wear on universal joints, bearings, spline connections, and replacing them if necessary.
  • Driveshaft Balancing: A process aimed at eliminating vibrations during shaft rotation, which is especially important for a comfortable and safe ride.
  • Driveshaft Replacement: Complete replacement of the driveshaft if diagnostics reveal significant damage or wear
