Abstract: A locking limited slip planetary differential for the transfer case of an all-wheel drive vehicle. First and second coaxially juxtaposed sun gears are mounted to first and second output shafts, respectively, for rotation therewith. A plurality of first planet gears are rotatably mounted on a carrier, each of which meshes with the first sun gear. A plurality of second planet gears is also rotatably mounted on the carrier. Each of the second planet gears meshes with the second sun gear and with an associated one of the first planet gears. A hydraulically actuated clutch pack is provided for selectively connecting the carrier to the first sun gear to limit relative rotation between the first output shaft and the second output shaft. The clutch pack is actuated by a swash plate pump mechanism provided on the first and second sun gears which supplies hydraulic fluid to the clutch pack when the first and second sun gears rotate relative to one another.

Abstract: A differential includes a planet gear through which two shafts coupled to laterally spaced road wheels of a motor vehicle are interconnected. The planet gear has a rotatable shaft with a brake mechanism coupled thereto. A braking force produced by the brake mechanism is transmitted through the differential to the road wheels depending on the rotational speeds of the road wheels. The brake mechanism may include either a turbine for producing a resistive force upon rotation thereof or a hydraulic damper comprising a hydraulic pump and a variable restriction.

Abstract: An automatic activation apparatus for a differential pawl which is independent of intervention by an operator of a vehicle, the invention controls the energy supply to the actuator by means of a control logic with two signal inputs. The control logic is fed a wheel slip signal directly at one signal input, and via a break-delay timing element at its other signal input. The control logic is thereby designed so that, by the excitation of both signal inputs, it switches into a standby position and then into its active position only upon the excitation of its signal input connected with the timing element.

Abstract: In an operation chamber 19 filled with silicone oil, there is provided a first resistance plate 21, which is spline-mated to the outer circumference of a first transmission shaft 3, and a second resistance plate 23, which is spline-mated to a second transmission shaft 9. These two resistance plates 21, 23 are clamped at both sides thereof by a clamp means formed from a pair of ring members 27, 29. The ring members 27, 29 are joined to a piston formed from the first transmission shaft 3, the sideplate 11, and a stopper ring 25. Then, when this piston moves in thrust and the clearance between the ring members 27, 29 shrinks, the blocks of the first resistance plate 21 and the second resistance plate 23 arranged side by side are clamped and abutted closely to produce a friction force at the resistance plates 21, 23.

Abstract: Each drive axle of a vehicle has an identical lockable differential which is controlled by a pneumatic control circuit. The control circuit is responsive to the accelerator pedal and the direction of movement of the vehicle. Each differential has a sliding collar which actuates one set out of two sets of sliding blocks to lock the differential. The collar has two cam surfaces on its inner periphery to alternately engage the two sets of sliding blocks. The sliding blocks engage chock slots located in the outer surface of a center ring and slide in radially disposed bores perpendicular to the axis of rotation of the differential. The pneumatic control circuit has electric switches which regulate the air flow and simultaneously engage all of the differential locks.

Abstract: An apparatus is provided for limiting the relative rotation between two drive members, including a differential having two input gears associated with the drive members, a carrier, and two coaxial differential gears carried by the carrier. One differential gear directly engages both input gears, while the other differential gear engages both input gears through idler gears. A threaded shaft is coaxially fixed to one of the differential gears and has a traveling nut thereon. A tubular shaft coaxially fixed to the other differential gear extends over the threaded shaft and has a spline connection with the traveling nut. Radially extending stops are provided on the threaded shaft and are adapted to engage axially extending tabs on the traveling nut when the drive members reach either selected limit of relative rotation.

Abstract: A differential gear drive having two output shafts each coupled through a differential gear train to a common input gear. The differential gear train comprises an annulus gear engaging the input gear, planet gears and a sun wheel. The output shaft is connected to a planet carrier and the output shaft is connected to the sun wheel. A pair of cam rings are rotatably coupled to the respective output shafts and are respectively coupled via clutch teeth to clutch rings respectively, which are engageable separately with a pair of meshing reference gears. The reference gear is rotatably fixed by a countershaft to the input gear. When both output shafts are driving against substantially equal torques the clutch rings are both disengaged from the reference gear and so the drive to each shaft is via the differential gear train. However when one of the output shafts commences to loose resistance torque, the respective clutch ring engages the reference gear and so a reaction via the reference gears is provided for the other output shaft, thereby maintaining traction in the case of a motor vehicle.

Abstract translation: 具有两个输出轴的差速齿轮传动装置，每个输出轴通过差速齿轮系联接到公共输入齿轮。 差速齿轮系包括接合输入齿轮，行星齿轮和太阳轮的环形齿轮。 输出轴连接到行星架，输出轴连接到太阳轮。 一对凸轮环可旋转地联接到相应的输出轴，并且分别经由离合器齿耦合到离合器环，所述离合器环可以与一对啮合的参考齿轮分开接合。 参考齿轮通过中间轴可旋转地固定到输入齿轮。 当两个输出轴都以大致相等的转矩驱动时，离合器环都与基准齿轮脱离啮合，所以每个轴的驱动通过差动齿轮系。 然而，当其中一个输出轴开始产生阻力扭矩减小时，相应的离合器环与参考齿轮啮合，因此通过参考齿轮提供反作用于另一个输出轴，从而在机动车辆的情况下保持牵引力。
