Model of Fully Floating Differential and Rear Wheel Mechanism Manufacturer,Supplier and Exporter in India

Product Code : EL-AELE-9425
Jlab Export is a leading Model of Fully Floating Differential and Rear Wheel Mechanism Manufacturer,and suppliers in India

In a fully floating rear axle, the axle casing carries the weight of the vehicle and the half shafts only drive the wheels. This model is built from original used heavy vehicle parts on a sturdy iron frame. It is sectioned to show the differential pinion, the crown wheel and the rear axle brake drums, and a crank handle drives it.

Load Path in a Fully Floating Axle

Each wheel hub of a fully floating axle runs on a pair of bearings fitted on the outside of the axle casing. The vehicle weight passes from the springs to the casing, then through those bearings to the hubs and wheels. At its outer end the half shaft is flanged and bolted to the hub, and its only job is turning the wheel.

At the centre of the axle the differential splits the drive between the two half shafts. When the vehicle runs straight, the cage, planet pinions and sun gears turn as one. On a bend the planet pinions rotate on their pin, so the outer wheel speeds up as much as the inner wheel slows down.

Lab Exercises for Automobile Students

Students can count the teeth on the pinion and crown wheel shown in the section and work out the final drive ratio. Turning the crank handle slowly, they then follow the drive from the pinion to each brake drum and name the parts it passes through.

For a wider picture, the teacher can show the whole drive line on the Car Chassis Rear Wheel Drive. It runs from the engine and gear box through the propeller shaft to the rear axle. The Differential Gear Assembly Actual Cut Section then lets students study the differential gears on their own.

Frequently Asked Questions

Which part carries the vehicle weight in a fully floating axle?
The axle casing does. The weight goes through the hub bearings on the casing to the wheels, so the half shafts carry only the driving torque and take no bending load.

What is the final drive in a rear axle?
It is the bevel pinion and crown wheel. Together they turn the drive from the propeller shaft through a right angle to the half shafts and give the last speed reduction before the wheels.

How does the differential let the wheels turn at different speeds?
The planet pinions in the differential cage mesh with sun gears on both half shafts. When one wheel has to turn faster on a bend, the pinions rotate on their pin and the other wheel slows by the same amount.

Why are brake drums shown on a differential model?
On a heavy vehicle the rear brakes sit at the axle ends, with each drum fixed to its wheel hub. Seeing the drums in section helps students relate the brakes to the hubs and bearings of the axle.
