In rear-wheel drive automobiles the central drive shaft ( or prop shaft ) engages the differential through a hypoid gear ( ring and pinion ).

API Category GL-4 designates the type of service characteristic of spiral-bevel and hypoid gears in automotive axles operated under moderate speeds and loads.
13.
Like the DE chassis on which it was based, the DC 27 had hypoid gear drive, independent front suspension, and hydro-mechanical brakes.
14.
Also note that the designations right hand and left hand are applied similarly to other types of bevel gear, hypoid gears, and oblique tooth face gears.
15.
Within the torque transfer unit is a short horizontal shaft and a hypoid gear set which turn the propeller shaft ninety degrees and moves it to the vehicle center line.
16.
The "'back cone "'of a bevel or hypoid gear is an imaginary cone tangent to the outer ends of the teeth, with its elements perpendicular to those of the pitch cone.
17.
The worm drive is not as efficient as a hypoid gear, and such trucks invariably have a very large differential housing, with a correspondingly large volume of gear oil, to absorb and dissipate the heat created.
18.
For practical purposes, it is often impossible to replace low efficiency hypoid gears with more efficient spiral bevel gears in automotive use because the spiral bevel gear would need a much larger diameter to transmit the same torque.
19.
In 1927, Gleason Works again led the innovation in this market, as it was the first machine tool builder to create machine tools to cut hypoid gears ( which are an advanced variant of spiral bevel gears ).
20.
"' Apex to back "', in a bevel gear or hypoid gear, is the distance in the direction of the axis from the apex of the pitch cone to a locating surface at the back of the blank.
