Torque convertor. Torque convertor. Axle shafts. Axle Shafts Design Rear axle construction In cases where the rear suspension is non-independent, the type of axle used is either a dead axle or a live axle.
The former only has to support the weight of the vehicle, where the latter has to fulfill this task and, in addition, contain a gear and shaft mechanism to drive the road wheels. Axle shafts The axle shaft (half shaft) transmits the drive from the differential sun wheel to the rear hub. Differential. Final drive diagram. Worm and wheel gear. Synchromesh. Introduction Early cars demanded much more skill from the driver than do modern machines.
One of the major skills that the driver had to acquire was that of changing gear silently and smoothly. Originally, gear changes were affected by sliding one gear out of mesh with another and then engaging another pair of gears. The small clearance between the sets of teeth demanded that the speeds of the gears that were to be engaged had to be accurately synchronized if noise and damage were to be avoided. This difficulty meant that the driver had to master the technique of "double declutching", a skill which is still of value to drivers of cars that have no synchromesh between first and second gears.
