摘要： A differential having an overrunning clutch provided. The differential includes an inertial compensation assembly that is configured to counteract movement of a roller cage relative to a clutch cam housing to prevent unintended roller cage and clutch cam housing engagements. Unintended roller cage and clutch cam housing engagements may occur when the differential is subject to rotational accelerations caused, for example by, vehicle acceleration/deceleration, sudden braking, sudden changes in traction, road irregularities, bumps, jumps, u-joint phasing, etc.

摘要： A drive control device includes: an estimated longitudinal acceleration acquisition part acquiring an estimated longitudinal acceleration of a vehicle based on an estimated driving force of the vehicle and a wheel speed of main drive wheels of the vehicle; an estimated lateral acceleration acquisition part acquiring an estimated lateral acceleration of the vehicle; an estimated tire load calculation part calculating an estimated tire load of the main drive wheels based on the estimated longitudinal acceleration and the estimated lateral acceleration ; and a drive mode selection part selecting one of a two-wheel drive mode driven only by the main drive wheels and a four-wheel drive mode driven by both the main drive wheels and auxiliary drive wheels. When the estimated tire load calculated by the estimated tire load calculation part is lower than a two-wheel drive threshold value, the drive mode selection part selects the two-wheel drive mode.

摘要： A torque sensing assembly of a differential of an axle assembly is described in the present disclosure. The differential may include a differential housing portion, a drive pinion positioned within the differential housing portion, a ring gear, a carrier, a differential pinion, a first side gear, a second side gear, a first bearing, a first bearing support, and the torque sensing assembly. The first bearing is coupled to the differential housing portion and rotatable with the carrier. The first bearing support is coupled to the differential housing portion and used to support the first bearing. The torque sensing assembly is coupled to the first bearing support and operable to measure a characteristic resulted from a separation force created between the drive pinion and ring gear.

摘要： A vehicle includes a first axle, a second axle, a driveshaft, a first clutch, a second clutch, a third clutch, and a controller. The second axle has first and second half shafts. The second axle has first and second wheels. The driveshaft is disposed between the first and second axles and is coupled to the second axle. The first clutch is configured to selectively couple the driveshaft to the first axle. The second clutch is configured to selectively couple the first wheel to the first half shaft. The third clutch is configured to selectively couple the second wheel to the second half shaft. The controller is programmed to repeatedly connect the first axle to the second axle via the driveshaft by alternating between (i) closing the second clutch and then the first clutch and (ii) closing the third clutch and then the first clutch.

摘要： A vehicle drive system configured to achieve a required driving force of braking force without changing an orientation of a vehicle in the event of slippage of a wheel. The vehicle drive system comprises: a torque generating device; a differential mechanism that allows a relative rotation between a right wheel and a left wheel; a differential restricting device that restricts a differential rotation between the right wheel and the left wheel; and a steering mechanism that controls a turning angle of pairs of the wheels. A first controller controls the relative rotation between the right wheel and the left wheel to be smaller than a predetermined value and second controller further controls a turning angle of the wheels controlled by the steering mechanism.

摘要： A vehicle driving-force distributing device includes: first connecting/disconnecting teeth disposed on the inner circumferential side of the ring gear; a connecting/disconnecting mechanism that includes a cylindrical member and a connecting/disconnecting sleeve including second connecting/disconnecting teeth and spline-fitted movably in the rotation axis direction and relatively non-rotatably to the outer circumferential side of the shaft insertion portion and that connects and disconnects a power transmission path between the ring gear and the differential case by moving the connecting/disconnecting sleeve in the rotation axis direction between a meshing position at which the second connecting/disconnecting teeth are meshed with the first connecting/disconnecting teeth and a non-meshing position at which the second connecting/disconnecting teeth are not meshed with the first connecting/disconnecting teeth; and a synchronizing mechanism disposed between the ring gear and the cylindrical member and reducing a relative rotation between the first connecting/disconnecting teeth and the second connecting/disconnecting teeth.

摘要： Methods and systems for a locking mechanism in an inter-axle differential are provided. A vehicle system, in one example, includes an electric motor coupled to a clutch assembly in a locking mechanism of an inter-axle differential coupled to a first axle and a second axle, the clutch assembly is configured to selectively disengage the locking mechanism, and in the disengaged configuration the locking mechanism permits speed differentiation between the first and second axles. The system further includes an electric motor brake coupled to the electric motor and configured to selectively apply a brake torque to the electric motor and the electric motor is configured to actuate the clutch assembly.

摘要： A drive module having a housing, an input pinion, a ring gear driven by the input pinion, a ring gear bearing supporting the ring gear for rotation relative to the housing, a pair of output shafts and a clutch that selectively transmits rotary power between the ring gear and the output shafts. The clutch includes a clutch input, which is rotatably coupled to the ring gear, a clutch pack separator that is rotatably coupled to the clutch input, a pair of clutch outputs, which are each coupled to a respective one of the output shafts, a pair of clutch packs, which transmit rotary power between the clutch input and a respective one of the clutch outputs, and a pair of apply pistons. The apply pistons are housed in the clutch pack separator.

摘要： In a transaxle, the transaxle includes a hydrostatic continuously variable transmission, at least one axle, a gear train for drivingly connecting the hydrostatic continuously variable transmission and the axle, a housing accommodating the hydrostatic continuously variable transmission, the axle, the gear train and storing an oil therein, and a reservoir tank connected to the housing so that the oil in the housing can be moved back and forth. The reservoir tank has a rectangular parallelepiped shape and is disposed on a side of a final reduction bull gear included in the gear train and above the axle along an axis direction of the axle.
