摘要： Frictional resistance is appreciably increased in parallel-axis/torque-proportioning types of automotive differentials to improve torque bias characteristics. A pair of sun gears (15, 17) receive, respectively, the ends of coaxial drive axles, and the sun gears (15, 17) are interconnected by at least one planetary pair of combination gears (23, 25) positioned in the housing circumferentially around the sun gears (15, 17). Each combination gear (23, 25) of the pair has a first engagement portion (27, 29) that is in mesh with a respective one of the sun gears (15, 17), and each also has a second engagement portion (31, 33) that is in mesh with its paired combination gear (23, 25). The first engagement portion (27, 29) of each combination gear (23, 25) is designed to develop end thrust on the combination gear to increase the frictional resistance between an end face of the gear and a bearing surface of the housing whenever the differential is subjected to a torque difference between its respective sun gears; and the gear's second engagement portion is specifically designed so that it develops either (a) no end thrust in a direction opposite to the direction of the end thrust developed by the first engagement portion or (b) end thrust in the same direction.

摘要： A continuously variable differential (10) uses a continuously variable transmission (50) that is rotated by drive torque and controlled to vary the speed ratio between its outputs. These, which previously transmitted power through the transmission, are connected with a pair of drive shafts such as opposed drive axles (17 and 18) that rotate with the transmission under drive power. Differentiation between the shafts transmits through the transmission via variable speed ratios that control the moment arms, mechanical advantages, and torque bias ratios. This arrangement allows the torque to be distributed according to sensed vehicle conditions. It can apply more torque to a wheel retaining traction when its opposite wheel slips, and it can apply a larger portion of the torque to wheels bearing more weight or to a faster rotating wheel on an outside of a curve.

摘要： A limited slip differential gear assembly has a rotating housing (1) containing meshing spur gears (16, 17) each turning a gear element (e.g. 23) which is externally helically toothed. Each gear element (e.g. 23) meshes with its own externally helically-toothed gear member (e.g. 30) which has a larger diameter and drives one of two output shafts (26, 27) between which differential movement is to take place. The meshing helical gear teeth have the characteristic that the efficiency of drive transmission in opposite directions is different and this provides the limited slip. As the axes of rotation of all rotating parts of the assembly are parallel, reduced constructional and operating costs are claimed.

摘要： The arrangement to oppose difference in relative rotational speed between two rotatable shafts (1, 2) including a primary element, made to rotate with one of the shafts, and a secondary braking element, made to rotate with the other shaft, whereby both sets of braking elements could be changed from a free running position to an engaged position in order to oppose the difference in rotational speed between the two shafts. One of the shafts is carrying a rotatable unit that is showing an angled surface, circular and slightly off 90 degree from the drive shafts. This unit is connected to one side of the braking element and rotating together and sideways movable relatively to the other braking element belonging to the other shaft. Fitted to one of the shafts is a rotatable unit containing a set of movable pistons, relatively running together with the angled surface, in such a way that when a torsional movement takes place at least one of the pistons is pushing back against the fluid system pressure.

摘要： A tractor locking differential (12, 18) is controlled by a solenoid operated hydraulic valve (34). The solenoid valve is in turn controlled by a logic circuit (36) which is responsive to signals received from a differential lock floor switch (32), application of brake lights (26) through the closing of a contact (28 or 30), and also from powering up the tractor. When the ignition (20) is turned on a flip-flop (50) within the circuit (36) will be cleared by action of a power up to clear circuit (58, 60, 64, 66) to dispose valve (34) in its unlocked position. After power up the operator can selectively lock or unlock the differential by application of momentary contact switch (32) which causes flip-flop (50) to toggle. When a brake light switch (28 or 30) is closed the flip-flop (50) will be cleared causing valve (34) to be disposed in its unlocked position.

摘要： A control system (29) for a lockable drive differential (22) of a vehicle (11) locks up the differential (22) during straight travel within a predetermined lower portion of the total range of vehicle speeds and unlocks the differential (22) during turns other than minor or momentary turning movements, manually initiated lock up being available to the operator during a turn if wheel slippage occurs. The control system (29) also maintains the differential (22) in an unlocked condition when the vehicle transmission (16) is in neutral or is shifted to a high speed range. By controlling the lockable differential (22) in response to changes of the mode of travel of the vehicle (11), rather than in response to speed differences between the differential output members (24, 26), better control of vehicle motion is realized and power dissipation and component wear in the differential is reduced. Although the control system (29) is adaptable to a variety of vehicles it is particularly advantageous in earthmoving vehicles such as loaders, for example, which are often operated on rough terrain providing poor traction.

摘要： A torque proportioning differential (10, 60, or 120) is modified to exhibit a bias ratio that varies with torque transmitted by the differential. Thrust forces (34 and 36, 88 and 90, or 144 and 146) generated within the differential are opposed by at least one pair of surfaces (38 and 40, 96, 98 and 104, 106, or 152, 154 and 156, 158) having different frictional characteristics. One of the surfaces (38, 96 and 98, or 152 and 154) opposes a portion of the thrust forces, and the other surface (40, 104 and 106, or 156 and 158) opposes a remaining portion of the thrust forces. A control member (54, 100 and 102, or 152) responsive to the transmitted torque limits the respective portions of the thrust forces opposed by each of the two surfaces.

摘要： The friction coupling of a differential has a friction disc set (31), which is axially subdivided by an intermediate ring (7) into an inner part (I) and an outer part (E). The friction disc set (31) is supported, in the direction of rotation, between the axle shaft (21) and the differential body (5) and can be compressed both by pressure movements of the axially mobile drive wheel (2A) due to the forces which separate or expand the teeth and by any external force, for example by means of a sliding bushing (8) against an external pressure plate (9). A stop ring (6) limits the expansion stroke (S) of the drive wheel (2A) toward the exterior and allows the intermediate ring (7), in the direction of expansion, only the clearance of the discs of the inner part (I) arranged in front of it on the side of the conical gear wheel. The discs of the inner part (I) can therefore be activated by a very small expansion stroke (S) without the discs of the outer part (E) being loaded simultaneously, which would entail a correspondingly longer expansion stroke (S). When an external force (F) is applied to the pressure plate (9), the discs of both parts (I, E) form a common disc set (31), because the intermediate ring (7) is thrust by the outer disc set (E) against the inner part (I) and both parts, including the intermediate ring (7), come to a standstill uniformly, with the inner part (I) resting against the cage (5) or its contact surface (10). This structure results in a more favorable distribution of the loads on the friction surfaces and shorter expansion strokes (S) as well as fast, smooth responses and less wear on the differential gear teeth.
