Abstract
The present invention relates to a transmission for cars, preferably with driving of the front wheels, comprising an engine (2), a gearbox (8), a final gear (20), first link mechanisms (16A, 16B) which connect each axle shaft (12A, 12B) to said final gear (20), second link mechanisms (18A, 18B) which connect the other end of each of said axle shafts (12A, 12B) to its driving wheel (6) and preferably an intermediate transmission (4) between the engine and the gearbox (8), said final gear comprising two planetary gears (20A, 20B) which give an exchange gear reduction of between 1.2:1 and 10:1.
Claims18
A transmission for a car,
- said car comprising a number of suspended wheel pairs, a transmission to drive at least one of said wheel pairs, to form at least one pair of drive wheels, and an engine to drive said transmission, said transmission comprising a gearbox having a primary transmission part, a secondary shaft and a pair of final gears connected to said secondary shaft, a pair of axel shafts connecting each one of said drive wheels with one of each said pair of final gears, a first pair of axle joints pivotally connecting each of said shafts to one each of said pair of final gears and a second pair of axel joints pivotally connecting each of said shafts to a respective drive wheel, to provide sufficient wheel suspension for said drive wheels, wherein each one of said final gears comprises planetary gear sets, which planetary gear sets provide an exchange gear reduction of between 1.2:1 and 10:1 of the rotational speed from said secondary shaft to said axle shafts.
