What is the effect of rear axle movement?
Consequence of the rear axle movement and deflection of the spring is, to alter the position of the final drive shafts also. This shafts is position may result in bending of the propeller shafts which is avoided by using a universal joint at the rear end of the propeller shaft.
How is the propeller shaft attached to the rear axle?
The propeller shaft is provided with two universal joints and also a sliding joint. The spring is fixed rigidity in the middle, to the rear axle. The front end of the spring is fixed rigidity on the frame, while the rear end is supported in a shackle. The driving thrust is transmitted to the frame by the front half the springs.
How is the axle attached to a differential?
Axle is the important part of the differential. The axle is a straight shaft that is fixed in location , it is combined with bearing or brushing use to mount rotating wheel or gears. The wheel or gear can be attached to it with a built in gearing or bushing.
Why are rear axle bearings and axle housing important?
The bearings and rear axle housing are key components of the rear axle assembly. They are designed to support and align the differential assembly and the drive axles. Notice that the bearings and axle housing are large, heavy-duty parts. This is to ensure they will stand up under hard usage.
When do the axle and output shaft joint angles equal?
When the transmission output shaft centerline and axle input shaft centerline intersect midway of the driveshaft, the joint angles are equal. However, due to the change to unequal joint angles during up and down axle movement, this is a more undesirable condition than parallel centerlines.
How is shaft deflection related to side load?
Shaft deflection due to side load This schematic illustrates how an overhung side load produces lateral shaft deflection through flexure of the shaft. When the location of the side load moves, the deflection can impact runout. Shaft deflection has to be considered when designing seal grooves and extrusion gap clearance.
What’s the maximum driveline angle for a short coupled drive?
Example: A short coupled driveshaft with a 15″ length would be limited to 3 degrees maximum operating angle. A 30″ shaft would be limited to 6 degrees. When the transmission output shaft centerline and axle input shaft centerline intersect midway of the driveshaft, the joint angles are equal.
What’s the maximum U-joint operating angle for a transmission?
When the transmission output shaft centerline and axle input shaft centerline are parallel, the u-joint operating angle permissible is length of driveshaft divided by five. Example: A short coupled driveshaft with a 15″ length would be limited to 3 degrees maximum operating angle. A 30″ shaft would be limited to 6 degrees.
