摘要： A power transmission device including a planetary gear, a differential gear and a differential case. The planetary gear includes a carrier, and pinion gears supported by pinion shafts. The differential gear includes a pair of bevel gears supported by a bevel gear shaft, and side gears engaged with the bevel gears. The carrier defines pinion shaft insertion holes in which pinion shafts are respectively inserted. The differential case defines bevel gear shaft insertion holes in which the bevel gear shaft is inserted. A straight line that penetrates the bevel gear shaft insertion holes overlaps with the pinion shaft insertion holes in a circumferential direction, and the bevel gear shaft passes through a center of a circle that connects the pinion shaft insertion holes. When viewed along an axial direction, the pinion shafts do not overlap the side gears, with the side gears being arranged radially inwardly than the pinion shafts.

摘要： To maintain smooth rotation of a pinion gear, a differential device includes: a differential case including a case main body and a bearing boss protruding from the case main body and rotatably supported about a first rotation axis; a side gear; and a pinion gear. An introduction groove for introducing lubricating oil into the case main body is formed on the bearing boss. An inner surface groove communicating with the introduction groove and extending toward the pinion gear is formed on the case main body. The inner surface groove includes a first groove portion and a second groove portion positioned radially outward from the first groove portion in the radial direction. The shape of at least a part of the first groove portion is a shape over which the lubricating oil is hard to climb during vehicle forward movement as compared with the shape of the second groove portion.

摘要： In a power transmission device in which a hub portion of a ring gear is fixed by a weld portion to a flange portion on an outer periphery of a transmission member, an annular groove that is recessed in the inner side of the axial direction is formed in a side face of the hub portion for making axial positions of the annular groove and the cavity part partially coincide with each other, the hub portion is narrowed partway along a part sandwiched between the cavity part and weld portion and the annular groove when viewed in a cross section transecting the annular groove, and a narrowed portion is set to have a thickness that alleviates residual stress produced around the weld portion of the flange portion by the force with which the flange portion and the hub portion pull each other in response to thermal shrinkage of the weld portion.

摘要： An axle assembly with a housing, an annular gear, a bearing, a differential, and a pair of output shafts. The housing has an annular hub. The annular gear is received in the housing. The bearing, which is a four-point angular contact bearing, supports the gear for rotation about an axis relative to the housing and has an inner bearing race, which is mounted on the annular hub, and an outer bearing race that is fixedly coupled to the annular gear. The differential is received in the housing and includes an input member, which is coupled to the annular gear for rotation therewith, and a pair of output members that are rotatable relative to the input member about the output axis. Each of the output shafts is coupled to an associated one of the output members for rotation therewith. One of the output shafts extends through the annular hub.

摘要： The invention relates to a spur gear differential (1), in particular for motor vehicles, comprising a planet carrier (2) for circulating about a differential axis (X), a first output spur gear (3), which is arranged coaxially to the differential axis (X), a second output spur gear (4), which is likewise arranged coaxially to the differential axis (X), and at least one pair (5) of planet gears (6, 7) that mesh with one another, said pair being rotatably arranged in the planet carrier (2), each planet gear (6, 7) meshing with one output spur gear (3, 4). At least one of the output spur gears (3, 4) and/or of the planet gears (6, 7) is conically toothed in such a way that, when the planet gears (6, 7) rotate relative to one another, the at least one of the output spur gears (3, 4) and/or of the planet gears (6, 7) is moved into a position in which a blocking effect is brought about. The invention further relates to a corresponding method for producing a spur gear differential (1) of this type.

摘要： An electronically locking differential assembly according to the present disclosure includes a differential case, a first and second side gear, a lock actuation mechanism, a first and second tone wheel, a first and second pickup sensor and a controller. The lock actuation mechanism includes a ramp plate that selectively moves between a locked state and an unlocked state. The first tone wheel has a first plurality of teeth formed on the differential case. The second tone wheel has a second plurality of teeth formed on the ramp plate. The first pickup sensor senses a position of the first plurality of teeth. The second pickup sensor senses a position of the second plurality of teeth. The controller determines whether the lock actuation mechanism is in the locked or unlocked state based on the respective positions of the first and second plurality of teeth.
