    Abstract: Pinion gears are rotatably carried within pinion gear receiving openings formed in a differential case. The inner pinion gear holding surfaces of the receiving openings are enlarged inwardly to form extensions to hold not only portions of the pinion gears that are located outwardly and that are to be held, but also part of inner meshing portions of the pinion gears that are disposed in meshing engagement with side gears in an overlapping manner. This construction prevents a tilting of the pinion gears and improves the durability.

    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 translation: 差速齿轮配备有可自动启动的选择性控制的锁定装置，即，它利用分化能量自行自锁。 因此，不需要控制信号来锁定锁定装置，而是分别针对两个可能的微分方向中的每一个选择性地进行锁定，从而控制它不会自动锁定。 这给差动齿轮四种不同的工作模式。 这些是：无论分化方向是开放的 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。 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，以便允许差速齿轮尽可能长地均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。

    Abstract: An improved differential gear mechanism is characterized by a lockout mechanism (129) operably associated with a latch member (119) that cooperates with a flyweight mechanism (53) to retard differentiating action in the differential gear mechanism. The lockout mechanism (129) includes a lockout member (131) positionable, in response to an input signal, in a normal condition and a lockout condition. In the normal condition, the lockout member (131) permits the latch member (119) to move freely between a locking position and an unlocking position. In the lockout condition, the lockout member (131) prevents the latch member (119) from moving into the locking position.

    Abstract: A differential gear mechanism, of either the locking or limited slip type, including a gear case (11) rotatably disposed within an outer housing (H) and a mechanism (37) to limit rotation of side gears (23,25) relative to the gear case, this rotation limiting mechanism including a member (41) which is axially moveable between a first position (FIG. 2) and a second position (FIG. 5). The mechanism includes a sensor assembly (95;101) and a sensor element (97;107) disposed adjacent the gear case (11). The axially moveable member includes a sensed portion (89) surrounding an annular surface (11S) of the gear case, and disposed between the annular surface and the sensor element, in one embodiment. Movement of the sensed portion corresponding to changes within the mechanism between unlocked and locked conditions results in the sensor assembly transmitting an electrical output. The vehicle control logic can know the condition of the differential mechanism and control certain other parts or functions of the vehicle accordingly.

    Abstract: A lightweight limited slip differential for a tubular or independent axle assembly. The differential biases the torque applied to the wheels through clutch rings engaged on the pinions. The pinions include a mating surface that engage a similar profile on the clutch rings. The clutch rings may be frictionally restrained or coupled together so that the pinion movement is restrained to bias the torque between the wheels.
