A front mid-engine, rear-wheel-drive layout (FMR) places the engine in the front half of the vehicle but behind the front axle, which likewise drives the rear wheels via a driveshaft. Shifting the engine's center of mass rearward aids in front/rear weight distribution and reduces the moment of inertia , both of which improve a vehicle's handling .
The Honda AX-1 is a modified version of Honda NX250 intended only for the Japanese market but was offered in Oceania.Using the same chassis as the NX250, the AX-1 came standard with alloy rims, aluminum Pro-Link rear suspension this time with a rear disc brake, dual round headlights, taller cams, stainless steel exhaust and different carburetor settings.
A beam axle, rigid axle, or solid axle is a dependent suspension design in which a set of wheels is connected laterally by a single beam or shaft. Beam axles were once commonly used at the rear wheels of a vehicle, but historically, they have also been used as front axles in four-wheel-drive vehicles.
The functions of this design are to change the axis of rotation by 90 degrees (from the propshaft to the half-shafts) and provide a reduction in the gear ratio. The components of the ring-and-pinion differential shown in the schematic diagram on the right are: 1. Output shafts 2. Drive gear 3. Output gears 4. Planetary gears 5. Carrier 6.
Splines on a front drive axle. An axle that is driven by the engine or prime mover is called a drive axle. Modern front-wheel drive cars typically combine the transmission (gearbox and differential) and front axle into a single unit called a transaxle. The drive axle is a split axle with a differential and universal joints between the two half ...
For road vehicles with more than two axles (e.g. some trucks), the wheelbase is the distance between the steering (front) axle and the centerpoint of the driving axle group. In the case of a tri-axle truck, the wheelbase would be the distance between the steering axle and a point midway between the two rear axles. [1]
The mechanical advantage of a simple machine like the wheel and axle is computed as the ratio of the resistance to the effort. The larger the ratio the greater the multiplication of force (torque) created or distance achieved. By varying the radii of the axle and/or wheel, any amount of mechanical advantage may be gained. [18]
The transmission and final drive for the front axle are combined into one housing alongside the engine, and a single drive shaft runs the length of the car to the rear axle. This is a favoured design where the torque is biased to the front wheels to give car-like handling, or where the maker wishes to produce both four-wheel drive and front ...
