Cardan Drive Shaft is a mechanical connection device that allows for angular deviation between two shafts, capable of transmitting rotational motion and torque between two non coaxial shafts. Its core function is to solve the connection problem caused by misalignment of the axis during power transmission.
The working principle is based on the cross axis structure: when the driving shaft rotates, the rotational motion is transmitted to the driven shaft through the linkage of the cross axis. Even if there is a certain angular deviation between the two shafts (usually up to 45 degrees), continuous torque transmission can be maintained. This design enables the transmission system to adapt to various complex installation conditions and motion states.
Cross axis Cardan Drive Shaft
The most common type consists of two Y-shaped forks and a cross axis
Simple structure, strong load-bearing capacity, and low cost
Allow a working angle of 15 ° -45 °
Widely used in automotive transmission systems
Double Cardan Drive Shaft
Connected by a spline shaft between two cross axis Cardan Drive Shafts
Can compensate for greater angular deviation and axial displacement
Used for long-distance transmission or situations with significant installation errors
Cage type constant velocity Cardan Drive Shaft
Adopting a spherical raceway and cage structure
Realize true constant speed transmission without speed fluctuations
The maximum working angle can reach 50 °
Standard configuration of modern front wheel drive vehicles
Trident constant velocity Cardan Drive Shaft
Structure between cross axis and cage type

Common fault phenomena:
Abnormal vibration: usually caused by wear, imbalance, or excessive angle
Abnormal noise: a manifestation of insufficient lubrication or damage to internal components
Oil leakage: seal aging and failure
Excessive clearance: wear of the cross shaft or bearing
Maintenance points:
Regularly check the lubrication condition and replenish special lubricating grease according to the instructions
Maintain the working angle within the design range and avoid extreme deflection
Regularly check the status of fasteners to prevent looseness
Pay attention to dust and water prevention, and avoid impurities from entering the bearing area
High speed applications require special attention to the dynamic balance state
Replacement standard:
Radial clearance exceeding 0.5mm
The cross axis shows obvious wear grooves
The bearing needle roller is broken or missing
Cracks or deformations appear on the outer shell
As a classic invention in the field of mechanical transmission, Cardan Drive Shafts have maintained strong vitality after more than a hundred years of development. From simple agricultural machinery to precision aerospace equipment, this technology continues to evolve and provide reliable solutions for various rotary power transmission needs. Understanding its principles and characteristics is of great significance for mechanical design, maintenance, and fault diagnosis.
