摘要： A limited slip differential (10) for use in model cars includes a pair of pressure plates (40) installed within a housing (20) and a differential element (50) is located between the pressure plates (40), so that when the rotation speed of a drive wheel (60,70) of the model car increases, the differential element (50) will move toward against the pressure plates (40) causing gear racks of the differential element (50) to frictionally contact the shafts of the helical gears (54) on a cross shaft (52). This lowers the rotation speed of the helical gears (54), while at the same time separately lowers the rotation speed of the drive wheel (60,70), and raises the rotation speed of the other drive wheel (70,60) allowing the model car to be able to turn at high speed.

摘要： Die Erfindung betrifft ein selbstsperrendes Differenzialgetriebe eines Kfz-Antriebsstrangs, mit einem mit einem Antriebselement in Triebverbindung stehenden und mehrere drehbare Ausgleichsräder (3) tragenden Differenzialkorb (2), mit zwei jeweils mit einer Abtriebswelle drehfest verbundenen und über die Ausgleichsräder (3) miteinander gekoppelten Abtriebsrädern (4, 5), und mit zumindest einer zwischen einem der Abtriebsräder (4, 5) und dem Differenzialkorb (2) angeordneten und durch das betreffende Abtriebsrad (4, 5) betätigbaren Reibungsbremse (9, 10). Um bei kompakter und kostengünstiger Bauweise eine exakter einstellbare Sperrwirkung und eine erhöhte Toleranz gegenüber einer Axialverschiebung der Abtriebsräder zu erzielen, ist das Differenzialgetriebe (1) als ein Kronenraddifferenzial mit kronenverzahnten Abtriebsrädern (4, 5) und mehreren umfangsseitig verteilt angeordneten und jeweils um eine radiale geometrische Achse drehbar in dem Differenzialkorb (2) gelagerten stirnverzahnten Ausgleichsrädern (3) ausgebildet.

摘要： A limited slip differential having a carrier (20) with a plurality of recesses (50) disposed symmetrically relative to a gear opening (21). Each of the recesses (50) includes a chamfer (526,528) leading to the gear opening (21). The gear opening (21) has a gear diameter (510), and each of the plurality of recesses (50) has a recess diameter (520). The gear diameter (510) intersects the recess diameter (520) of each of the plurality of recesses (50) at corresponding first and second intersections. An acute angle (θ) is formed between a line tangent to the recess diameter (520) at the first or second intersection and a line tangent to the respective the first or second chamfers (526,528) of between approximately 30 degrees and approximately 32 degrees.

摘要： A one-piece differential casing for a parallel-axis differential assembly is provided. The integral casing includes a drum segment defining an internal chamber and a flange segment extending radially from the outer periphery of the drum segment. The casing further includes a window aperture extending through the drum segment that communicates with the chamber, a pair of sockets formed in the axle openings to rotatably support the side gears therein, and paired sets of gear pockets. A set of first pinion pockets are formed as elongated bores which communicate with the internal chamber and have an opening through one end wall of the drum segment. In addition, a set of second pinion pockets are formed as elongated bores which communicate with the internal chamber and have an opening through the opposite end wall of the drum segment. The first and second pinion pockets are arranged in paired sets and each has an axis which is parallel to the axis of the axle openings. After pinions are installed through the openings in the ends of the first and second pinion pockets, plugs are mounted in the openings to enclose the pockets, thereby retaining the pinion in the integral casing.

摘要： A differential apparatus (7) comprises: a differential casing (21) rotated by an engine power; a plurality of pinion gears (65, 66) slidably housed in accommodation holes (63, 64) formed in the differential casing: a pair of side gears (35, 37) geared with each other via the pinion gears, two opposing end surfaces thereof being slid each other directly or via a thrust washer (61); and a block member (47, 91, 97) interposed between two inner circumferential surfaces of the two side gears so as to center the side gears, respectively. In particular, at least one oil sump (77, 79; 95; 101) is formed between the block member and the side gears, to supply lubricant to sliding portions between the block member (47, 91, 97) and the side gears (35, 37) and between two opposing end surfaces of the two side gears, by a centrifugal force generated by the rotating differential casing. Further, it is preferable to further form at least one central oil passage (301, 303, 305) at the centering portion (365) so as to extend from an inner circumferential side to an outer circumferential side of the boss portions (357, 359) of the two side gears (353, 355). Further, it is also preferable to form at least two radial oil passages (881, 885; 977, 978) between inner wall surfaces of the differential casing (821, 921) and the side gears (835, 837; 939, 941), respectively in such a way that a radially inward end thereof communicates with the helical oil passage (877, 879; 979L, 979R) and a radially outward end thereof communicates with sliding portion between the side gear and the differential casing, respectively.

摘要： The compact, all-gear full-traction differential includes meshing pairs of side-gear worms and worm-wheel balance gears having a "hybrid" design. Preferably, the teeth of each side-gear worm have an involute profile but are cut with only plunge feed, while the teeth of the worm-wheel portions of the balance gears are helicoid worms having tip and root modifications made by a convex-shaped cutter. The side-gear worm teeth have a helix angle equal to or greater than 45° and significantly chamfered ends, and the gears are designed to provide a gear ratio between 1.5:1 and 2.5:1. The numbers of teeth in the spur-gear portion and worm-wheel portion of each balance gear and in each side-gear worm are all divisible by 2 or by 3, preferably by both 2 and 3.
