    摘要： A drive-force-distribution control device includes an input-side bevel gear and an output-side bevel gear, a center shaft, left and right clutches, a housing, a bearing and a shim member. The output-side bevel gear is supported on the center shaft such that the output-side bevel gear meshes with the input-side bevel gear. The housing can be divided in the radial direction of the output-side bevel gear. The bearing is disposed at one end of the center shaft. The shim member is inserted in an axial-direction gap between the housing and the bearing. The output-side bevel gear and the center shaft can be attached to the housing from the radial direction. The axial end of the center shaft is located towards the other end with respect to the axial end of the bearing.

    摘要： In a transient control computing section, a left-right drive force difference transient control gain computing section finds a left-right drive force difference transient control gain α that is smaller than 1 in a region where a target yaw rate change rate is small, i.e., a low speed steering region, and a left-right drive force difference transient control computation value calculating section finds a left-right rear wheel drive force difference transient control computation value. The transient control computing section then multiplies the left-right rear wheel drive force difference transient control computation value by the left-right drive force difference transient control gain α to calculate the left-right rear wheel drive force difference transient control amount and contributes the same to a drive force distribution control for left and right wheels (left and right rear wheels).

    摘要： Upon determining than an over-steered state exits, a feedback control coefficient for a rear wheel total drive force is set to 0 and a feedback control coefficient for a rear wheel drive force difference is also set to 0 to impose a two-wheel drive state. As a result, it is possible to avoid a turn cruising instability caused by cruising in four-wheel drive in an over-steered state. Upon determining that an under-steered state exists, the feedback control coefficients are set such that four-wheel drive is allowed but a drive force difference is not set between the left and right rear wheels. As a result, when the under-steered state exists, excellent traction can be enjoyed by operating in four-wheel drive and the phenomenon of riding up a canted road surface due to a drive force difference set between the left and right rear wheels can be avoided.

The differential has a differential case, a pair of pinions rotatably supported in the differential case, a pair of side gears meshed with the pinions and secured to respective axles of the vehicle, and a final reduction gear secured to the differential case. A fluid-operated clutch controls the differential operation of the limited slip differential. The clutch has an outer drum integral with the differential case, an inner drum connected to one of the side gears, a plurality of outer disks secured to the outer drum, a plurality of inner disks secured to the inner drum, a piston slidably mounted in a piston chamber and operated by oil supplied to the piston chamber for engaging the outer drum with the inner drum, the outer disks and inner disks being disposed alternately with each other. Sealing members separate oil supplied to the piston chamber from oil for lubricating the final reduction gear.

    摘要： A drive system for a tractor. The output from a hydrostatic transmission is connected to the rotatable input member of a differential, while the output shafts of the differential are each connected to a drive wheel of the tractor. A clutch interconnects one output shaft of the differential with the input member, and when the clutch is engaged, the output shafts will rotate at the same speed, acting as a solid axle. The steering column of the tractor is connected to a steerable wheel, and when the steering column is rotated through a predetermined arc of about 15.degree., a linkage interconnecting the steering column and the clutch act to disengage the clutch, so that the drive wheels are permitted to rotate at different speeds. Rotation of the steering column through a greater arc of about 80.degree. will automatically operate a brake associated with the inside wheel in the turn. At higher speeds, rotation of the steering column through a given arc will also automatically reduce the speed of the hydrostatic transmission to eliminate possible instability in a tight turn.

    摘要： A behavior control device for a four-wheel drive vehicle that is applied to a vehicle which comprises a center differential device that transmits a driving force from a driving device to front and rear wheel rotation shafts, and permits differential of the front and rear wheel rotation shafts; and a braking force distribution ratio of the front and rear wheels being set to a value in which a proportion of front wheels is larger than that in an ideal distribution ratio. The behavior control device comprises a differential limiting device that changes the limitation degree of a differential between the wheel rotation shafts, and a control unit that controls the differential limiting device to increase the limitation degree of the differential during the vehicle is braked as a degree of an understeer state of the vehicle is high.
