The drive shaft is the shaft that can transfer power in the transmission of universal transmission device. It is a rotating body with high speed and little support, so its dynamic balance is very important. General transmission shaft before delivery into action balance test, and in the balancing machine has been adjusted. For front engine and rear-wheel drive vehicles, it is the shaft that transmits transmission rotation to the main reducer. It can be several knots, and the joints can be connected by universal joints.

Drive shaft classification

One, according to the elasticity can be divided into

According to whether the universal joint has obvious elasticity in the direction of torsion, it can be divided into rigid universal joint drive shaft and flexible universal joint drive shaft.

1. Rigid universal joint: transfer power by hinged connection of parts.

2. Flexible universal joint: transfer power by elastic parts, with buffering and damping.

Two, angular rate can be divided into

The rigid universal joint can be divided into unequal velocity universal joint (such as cross shaft type universal joint), quasi constant velocity universal joint (such as double type universal joint, three pin type universal joint) and constant velocity universal joint (such as ball cage type universal joint, ball fork type universal joint). Constant and unequal speed, refers to the driven shaft in rotation with the drive shaft, the rotation Angle rate of the two is equal, of course, the drive shaft and the drive shaft average speed is equal.

1. Constant velocity universal joint:

A universal joint where the angular velocity of the main and driven axes is still equal when the Angle between the two axes changes is called a constant velocity universal joint or a constant angular velocity universal joint. They are mostly used in steering drive axles, broken drive axles and other wheel transmission devices, mainly used for power transmission in cars.

2. Variable velocity universal joint:

The joint where the angular velocity of the main axis and the driven axis is not equal when the Angle between the two axes changes is called the variable velocity universal joint, also called the cross axis universal joint.

Cross shaft type rigid universal joint drive shaft is widely used in automobile transmission system and has a long history. When the car is rear-wheel drive, the cross shaft universal joint drive shaft is often used. For some high-grade cars, there are also constant speed ball head. When the car is front wheel drive, it is often used constant speed universal joint - constant speed universal joint is also a kind of transmission shaft, just a different name. Usually referred to as the drive shaft generally refers to the cross shaft type rigid universal joint drive shaft. Cross shaft type rigid universal joint is mainly used to transfer Angle changes, generally by the edge fork, cross shaft with needle roller bearing assembly, universal joint fork or sliding fork, middle connection fork or spline shaft fork, needle roller bearing axial fasteners, etc.

Three, according to the elasticity can be divided into

According to the transmission torque can be divided into mini car drive shaft, light car drive shaft, medium car drive shaft, heavy car drive shaft, engineering car drive shaft.
