摘要： A transfer case is provided utilizing dual planetary gearsets to provide a low gear ratio that can be engaged and disengaged on the fly without binding of gears. The transfer case provides an option for engaging the front, rear, both front and rear, or none of the wheels of a vehicle and is especially suited for off road vehicles such as rock crawlers.

摘要： A sun gear 6 is concentrically, rotatably disposed inside an internal gear 4. Plural planet gears 8, carried by a planetary carrier 10, are disposed between and in meshing engagement with the internal gear 4 and the sun gear 6. The planetary carrier 10 is connected to a shaft extending from an engine while the internal gear 4 and the sun gear 6 are connected to output shafts. The internal gear 4 is molded by a plastic working, followed by a thermal treatment including soft-nitriding, a nitriding and a carburizing hardening step. The inner surface of the internal gear 4 is formed with internal gear teeth 4b, except for an axial portion 4d, while a spline groove 4a is formed on the outer surface of the internal gear 4 at a location corresponding to the portion 4d where no internal teeth 4b are formed for engagement with a spline 2a on a housing 2. The internal gear 4 is reduced in size while improving the mechanical strength thereof.

摘要： A clutch drum is engaged to the rear part of a carrier of a center differential device. A clutch piston, which is rotated together with the rear drive shaft while allowing it to retractively move in a direction along a rear drive shaft, is provided within the clutch drum. Pinion shafts are protruded from the rear end face of the carrier to form protruded parts, which are confronted with the front end face of the clutch piston. A cam part, which is in sliding contact with the protruded parts, is formed on the front end of the clutch piston. When the carrier and the rear drive shaft relatively rotate, the protruded parts retractively move the clutch piston along cam crests of the cam part to press a clutch mechanism.

摘要： A differential apparatus for controlling the wheel speed of a vehicle includes a primary driving input, and first and second output shafts. The differential apparatus also includes a first planetary gear system in driving engagement with the first output shaft for rotating the first output shaft, and a second planetary gear system in driving engagement with the second output shaft for rotating the second output shaft. At least one auxiliary input mechanism selectively drives the first and second planetary gear systems for rotation in opposite directions to effect different rotational speeds to the first and second output shafts, thereby controlling the wheel speed of the vehicle.

摘要： The present disclosure relates to a gearing arrangement for a tandem axle assembly for a vehicle that reduces parasitic losses associated with the bearings of a drive pinion. The gearing arrangement includes a first helical gear in driving engagement with an input shaft and a portion of an interaxle differential; a second helical gear coupled to a pinion shaft with at least two bearings mounted on either side of the second helical gear on the pinion shaft; and a drive pinion coupled to the pinion shaft and meshingly engaged with a ring gear. The ring gear is in driving engagement with a forward differential assembly. The first helical gear and second helical gear are meshingly engaged and have a predetermined gear ratio.

摘要： A vehicle planetary gear device includes a ring gear, a sun gear, and a carrier, and pinions housed in the carrier. A penetration hole formed in a hollow cylindrical portion of the carrier has two inner wall surfaces that face an outer peripheral surface of a pinion. One of the inner wall surfaces has a curvature radius larger than the radius of the pinion, and has a curvature center that is apart from the radius center of the pinion gear. The pinion is disposed with respect to the carrier with a predetermined space formed between the one of the inner wall surfaces and the outer peripheral surface of the pinion, and thereby slides along a radial direction of the carrier.
