ABSTRACT:
An automotive final drive assembly which utilizes a worm gear system for speed reduction between a vehicle's engine and drive wheels. The final drive assembly is capable of reducing the high speed from the engine and delivering it to the vehicle's drive wheels, all within an extremely compact space. Furthermore, the large contact area between the thread of the worm and the teeth of the worm gear provides for a high load capacity with relatively low friction, such that the final drive assembly is efficient and operates at lower temperatures. Finally, the worm gear is a ball worm gear having a spheroidal shape. As a result, the structure of the final drive assembly is simplified and suitably rigid to maintain the threads of the worm in mesh with the teeth of the worm gear.
