  • Four-wheel locking system for a motor vehicle
    Patent number: 4986800
    Abstract: In the drive line of a motor vehicle, a planetary transmission is arranged as four-wheel locking system, a braking device acting upon the planet carrier of this planetary transmission. The planetary transmission includes an input sun gear, an output sun gear disposed coaxially next to it, and planet wheels mating simultaneously with both sun gears. In order to keep friction losses low and avoid a self-locking in the planetary transmission, the real pitch module of all gear wheels is as small as possible and proportional to the driving torque to be transmitted, and the operational pressure angle is as large as possible.
