The driveline of the Automotive

 

The driveline of the vehicle 

The driveline is the drive chain of the Automotive.

An assembly of one or two universal joints connected to a propeller shaft, slip joint used to transmit power from the transmission (gearbox) to the drive axle. A chain that transmits power between the shaft joint to the drive wheel.

 

Propeller Shaft

A propeller shaft is provided to cope with and maintain the distance between the gearbox and differential and to adjust with the varied length and angles.

Purpose of universal joint

The purpose of the universal joint is to transmit power (torque) even at varied angles of the transmission system.

Types of universal joint 

1) Cross (spider) type universal joint. 

2) Slip joint  type universal joint and 

3) Constant-velocity (CV) universal joint.

 Cross (spider) type universal joint. 

In universal joint, the two yokes in which one is connected to the driveshaft and the other one is connected to the living driven shaft at right angles to each other by a cross (spider). Needle types

 bearing is mounted between yoke and cross ends.

Slip Joint type universal joint 

It has outside splines on the shaft and matching internal splines in a matching hollow shaft or yoke. When assembled, the spline causes the shaft to rotate together while they can move back and forth. This change the length of the propeller shaft or drive shaft. 

Constant-Velocity (CV) universal joint 

Constant-Velocity universal joint, in which the speed of the input and output shaft remains the same, regardless of the angle between the shaft.

Various types of CV joint include the Rzeeppa, double offset & tripod, most widely-used outer CV joint is Rzeppa CV joint type. 

The main advantage of the Constant-Velocity universal joint is the elimination of transmitted speed fluctuation.
