Abstract: A differential gear is equipped with a selectively controllable locking device which is self energizing, i.e. it utilizes the differentiation energy to self-lock on its own accord. The control signal is therefore not needed to lock the locking device but rather to selectively, separately for each of the two possible differentiation directions, control it to not lock itself. This gives the differential gear four different working modes. These are: open regardless of differentiation direction; open in one differentiation direction but self-locking in the other direction; open in the other direction but self-locking in the first one; self locking regardless of differentiation direction. A control unit is supplied with sensor data of the present "driving situation". The control unit has a steering strategy. With the right steering strategy it can regulate the control signal so as to permit the differential gear to equalize the torque at each output shaft for as long as possible but still to practically eliminate the risk of one wheel spin.

Abstract: The present invention relates to a differential gear equipped with a selectively controllable locking device. Said locking device is self energizing, i.e. it utilizes the differentiation energy (i.e. the possible torque imbalance) to self- lock on its own accord. The control signal is therefore not needed to lock the locking device but rather to selectively control it not to lock itself. Said control signal is designed to, separately for each of the two possible differentiation directions, allow or not allow the locking device to lock. In this way the differential gear will get four different working modes. Said working modes are respectively; open regardless of differentiation direction; open in one differentiation direction but self-locking in the other direction; open in the other direction but self-locking in the first one; self-locking regardless of differentiation direction. A control unit is supplied with sensor data of the present "driving situation". Said control unit has a steering strategy. With the right steering strategy it can regulate the control signal so as to admit the differential gear to equalize the torque at each output shaft for as long as possible but still to practically eliminate the risk of one wheel spin.

Abstract translation: 本发明涉及配备有选择性控制的锁定装置的差动齿轮。 所述锁定装置是自激能的，即它利用微分能量（即可能的扭矩不平衡）自己自锁。 因此，不需要控制信号来锁定锁定装置，而是选择性地控制该锁定装置以使其不被锁定。 所述控制信号被设计为分别用于两个可能的微分方向中的每一个，允许或不允许锁定装置锁定。 以这种方式，差速齿轮将获得四种不同的工作模式。 所说的工作模式分别是 开放无论分化方向; 在一个分化方向开放，但在另一个方向自锁; 在另一个方向打开，但在第一个方向自锁; 自锁无论分化方向如何。 向控制单元提供当前“驾驶状况”的传感器数据。 所述控制单元具有转向策略。 通过正确的转向策略，它可以调节控制信号，以允许差速齿轮尽可能长地平衡每个输出轴处的扭矩，但仍然实际上消除了一个车轮旋转的风险。
