Differential gear e.g. roller bearing differential gear, for transmission of drive torque to front and rear wheels of all-wheel-driven vehicle, has paths formed in drive gears with gradient wave-shaped in radial direction of rotation axis
Differential gear e.g. roller bearing differential gear, for transmission of drive torque to front and rear wheels of all-wheel-driven vehicle, has paths formed in drive gears with gradient wave-shaped in radial direction of rotation axis
The gear (1) has a drive disc (2) for synchronization of a set of rolling bodies (3) i.e. ball, during rotation of the rolling bodies around a rotation axis (7). The rolling bodies are arranged in paths (11a, 11b) of two drive gears (4) to transfer torque from the drive disc to one or both drive gears, where the paths are formed as grooves. The paths circulate the common rotation axis, where the gradient of the paths is wave-shaped in a radial direction of the rotation axis.
