Abstract
A drive system driving front wheels and rear wheels of a vehicle includes a powertrain comprising an output shaft, a rear driveshaft coupled to the rear wheels, a drive mechanism coupling the output shaft to the rear wheels, a front driveshaft shaft coupled to the front wheels and a prop shaft coupling the rear driveshaft and to the front driveshaft.
Claims10
A drive system driving front wheels and rear wheels of a vehicle comprising:
- a powertrain comprising an output shaft, said output shaft comprising a first pulley or a first sprocket;
- a rear differential having a rear transaxle shaft coupled to the rear wheels through a pair of rear half shafts, said rear transaxle shaft having a second pulley or a second sprocket affixed thereto;
- a belt or a chain directly connecting the first pulley or first sprocket to the second pulley or the second sprocket;
- a pair of front half shafts coupled to the front wheels;
- a front coupler coupling the pair of front half shafts to a prop shaft;
- and
- the prop shaft disposed below the powertrain and directly coupling the rear differential to the front coupler.
