The front drive axle is providing the force to drive the truck. In fact, only one wheel of that axle is actually moving the truck and trailer down the road. Some simple vehicle designs, such as leisure go-karts, may have a single driven wheel where the drive axle is a split axle with only one of the two shafts driven by the engine, or else have ...
Steering knuckle. In automotive suspension, a steering knuckle or upright is that part which contains the wheel hub or spindle, and attaches to the suspension and steering components. [1] The terms spindle and hub are sometimes used interchangeably with steering knuckle, but refer to different parts. The wheel and tire assembly attach to the ...
Direct-drive mechanisms are used in applications ranging from low speed operation (such as phonographs, telescope mounts, video game racing wheels and gearless wind turbines) [14] [15] [16] to high speeds (such as fans, computer hard drives, VCR heads, sewing machines, CNC machines and washing machines.)
Contents. Differential (mechanical device) A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others. A common use of differentials is in motor vehicles, to allow the wheels at each end of a drive axle to rotate at different speeds while cornering.
In the case of French TGV power cars, a motor mounted to the power car's frame drives each axle; a "tripod" drive allows a small amount of flexibility in the drive train allowing the trucks bogies to pivot. By mounting the relatively heavy traction motor directly to the power car's frame, rather than to the bogie, better dynamics are obtained ...
A double wishbone suspension is an independent suspension design for automobiles using two (occasionally parallel) wishbone -shaped arms to locate the wheel. Each wishbone or arm has two mounting points to the chassis and one joint at the knuckle. The shock absorber and coil spring mount to the wishbones to control vertical movement.
A direct-drive simulator steering wheel (sometimes abbreviated " DD ") is a simulator steering wheel with a direct-drive mechanism between the drive and output, i.e. without gearing (as opposed to simulator steering wheels with reduction gearing via gears or belts [1][2][3][4]), and is used similarly as with other simulator steering wheels for ...
This design is still in use in trucks and other large vehicles, where rapidity of steering and direct feel are less important than robustness, maintainability, and mechanical advantage. The worm and sector was an older design, used for example in Willys and Chrysler vehicles, and the Ford Falcon (1960s). To reduce friction, the sector is ...
