Cardan Drive Shaft for Automobile

The structure and function of the cardan drive shaft for automobile for car are somewhat similar to the structure and function of the human limb, which makes the angle between the connection parts change within a certain range.

 

In order to adapt to the angle change caused by the power transmission, steering and bouncing up and down during the driving process of the car, a universal joint is commonly used between the front drive axle axle and the wheel axle.

 


However, due to the limitation of the axial dimension and the large declination required, a single universal joint cannot make the instantaneous angular velocity of the output shaft equal to the instantaneous angular velocity of the input shaft.

 

It is easy to cause vibration, aggravate the damage of components, and produce a lot of noise. Therefore, various constant velocity universal joints have been widely used.

 

Automobile cardan drive shaft for automobile is a key component of automobile transmission shaft. Cars are moving objects. On a rear-drive vehicle, the engine, clutch, and transmission are mounted on the frame as a whole, and the drive axle is connected to the frame through an elastic suspension. There is a distance between the two and they need to be connected. The road is uneven and jumps.

 

The cardan drive shaft for automobile is generally composed of a cross shaft, a cross bearing and a flange fork. The universal joint is a key component of the automobile transmission shaft.

 

On vehicles driven by the front wheels of the engine, the universal joint drive shaft is installed between the transmission output shaft and the input shaft of the transaxle main reducer; while vehicles driven by the engine front wheels omit the transmission shaft, and the universal joint is installed on the half shaft between.

 

The front axle and wheels responsible for driving and steering. The angle and distance between the output shaft of the transmission and the input shaft of the final drive of the transaxle will change due to road jumps, load changes, or differences in the installation positions of the two assemblies. Therefore, a "variable strain" device is needed to solve this problem, so a universal joint is produced.


Cardan Drive Shaft for Front-Drive Vehicles

 

On front-drive vehicles, two car cardan drive shaft for car are used for each axle. The cardan drive shaft for car close to the transmission shaft is an inner half shaft universal joint and an outer half shaft universal joint close to the transmission shaft.

 

During vehicle operation, the angle and distance between the output shaft of the transmission and the input shaft of the final drive of the transaxle will change due to road pulsation, load changes, or the difference in position between the two assemblies.

 


Cardan Drive Shaft for Rear-Drive Vehicle



On a rear-drive vehicle, the engine, clutch, and transmission are mounted on the frame as a whole, and the drive axle is connected to the frame through an elastic suspension. There is a distance between the two and they need to be connected.


Therefore, the cardan drive shaft for car of the rear drive car adopts the form of double universal joint, that is, there is one cardan drive shaft for car at each end of the transmission shaft. The role of the universal joint is to make the angles at both ends of the transmission shaft equal to ensure that the instantaneous angular velocity of the output shaft and input shaft are always equal.

 

The development of the automobile industry and users' higher pursuit of automobile use and steering. The demand for better power, maneuverability and comfort has prompted the advent of FF and 4WD vehicles: their front wheels must have two steering and driving functions.

 

As a steering wheel, the wheels need to deflect a certain angle within a certain steering angle range. As the driving wheels, the half shafts need to have the same angle during the wheel deflection. Speed constantly transfers power from the final drive to the wheels.

 

The mechanism that transmits power between two shafts that do not overlap and whose position changes frequently is a constant velocity cardan drive shaft for car. The half shaft of the steering axle cannot be made into a whole plane, and the entire surface should be segmented.

 

The two axles are connected by a constant velocity universal joint between the wheel and the half axle. Even if the rear-wheel drive is used, due to the requirements of habitability, the wheels and axles of the half-axle are not consistent with the use of the independent suspension, and constant-speed universal joint drive is required.

 

In modern automobiles, the automobile cardan drive shaft for car transmission device is composed of a constant velocity universal joint, a transmission shaft and a bracket. The constant velocity cardan drive shaft for car connects the two axes so that they move at the same angular velocity.
