A wheel end disconnect assembly includes a housing, a shift ring, a shift fork and an actuator. The shift ring is supported for axial translation relative to the housing between a connected position in which the shift ring couples an input member to a wheel hub for rotation therewith and a disconnected position in which the input member and the wheel hub are rotatable relative to each other. The shift fork includes a first arm portion, a second arm portion, and an input portion extending from a junction of the first and second arm portions. The shift fork is pivotably coupled to the housing at the junction of the first and second arm portions. The actuator is configured to move the input portion to pivot the first and second arm portions such that the first and second arm portions translate the shift ring between the connected and disconnected positions.

Proposed is a disconnector apparatus including: a support ring provided in a differential casing and configured to support a pinion gear mounted therein; a clutch ring configured to be coupled to or decoupled from the support ring in the differential casing; an actuator including an armature provided at an outer side of the differential casing opposite to the clutch ring, the actuator being configured to couple the clutch ring and the support ring by pulling, with an electromagnetic force, the armature connected to the clutch ring by an application rod; and an elastic member coupled to a portion of the application rod in the differential casing and having one end in contact with the differential casing and the other end in contact with the clutch ring to elastically support the clutch ring.

A vehicle control system has a plurality of subsystem controllers including an engine management system 28, a transmission controller 30, a steering controller 48, a brakes controller 62 and a suspension controller 82. These subsystem controllers are each operable in a plurality of subsystem modes, and are all connected to a vehicle mode controller 98 which controls the modes of operation of each of the subsystem controllers so as to provide a number of driving modes for the vehicle. Each of the modes corresponds to a particular driving condition or set of driving conditions, and in each mode each of the functions is set to the function in mode most appropriate to those conditions.

A sensorless clutch state feedback method is provided including a driveline disconnect. To engage the sensorless disconnect, respective speeds of a motor assembly and the sensorless disconnect are synchronized to within a speed delta threshold of each other, a control system facilitates the engagement of the motor assembly and the sensorless disconnect, and the control system determines the success of the engagement by the motor speed response of the motor assembly (e.g., whether the presence of a load is detected).

An all-wheel drive system includes a center differential, a limited-slip differential clutch, a front-wheel torque transmission system, a rear-wheel torque transmission system, and a controller. The center differential distributes torque between front and rear wheels of a vehicle. The limited-slip differential clutch limits a differential operation of the center differential in accordance with an engaging pressure, and changes a front-rear torque distribution ratio between the front and rear wheels. The front-wheel torque transmission system transmits torque between the center differential and the front wheels. The rear-wheel torque transmission system transmits torque between the center differential and the rear wheels. The controller adjusts the engaging pressure based on a driving state of the vehicle. Reduction ratios of the front-wheel and rear-wheel torque transmission systems are set different from each other. The center differential is configured such that the front-rear torque distribution ratio is initially unequal and is changeable.

An autonomous mobile robot may use an improved steering system. The improved steering system may include a steering motor that is operably coupled to a motor shaft. The motor shaft may be aligned at an offset position relative to a center axis of the autonomous mobile robot. The motor shaft may be operably coupled to a front and rear steering linkage. Each steering linkage may include a pitman arm that is coupled to the motor shaft and a drag link. The drag link may be coupled to a first steering arm and a tie rod. The tie rod may also be coupled to a second steering arm. The first steering arm may be coupled to a first wheel and the second steering arm may be coupled to a second wheel.

An agricultural machine transmission has a powershiftable main group arranged upstream or downstream of a powershiftable split group in the direction of force transfer. The split group has an input shaft, an output shaft, and powershift elements, which when selectively actuated permit configurations of at least six different forward gears and at least three different reverse gears between the input shaft and the output shaft of the split group. A driveshaft of the main group is connectable by a first powershift clutch to a first input shaft and is connectable by a second powershift clutch to a second input shaft of the main group. Spur gear stages of the main group can be integrated into the force transfer path by actuating an associated shift element, coupling an associated input shaft to the drive shaft of the main group by configuring a respective gear of the main group.

A power divider unit including an input shaft, a drive gear disposed around the input shaft, an inter-axle differential assembly coupled to the input shaft, an output side gear coupled to the input shaft, and a locking system for the power divider unit. The locking system is configured to passively lock the inter-axle differential assembly. The locking system includes a ramped first clutch member in selective engagement with the drive gear, a mating second clutch member configured to engage the first clutch member, a clutch pinion, and a slip clutch assembly. The second clutch member and the first clutch member rotate at different speeds, the clutch pinion rotates and causes the slip clutch assembly and second clutch member to rotate at a speed of the input shaft, causing the first clutch member to mate with the first clutch member.

An axle assembly having an input shaft, an output shaft, and an interaxle differential unit. The interaxle differential unit includes a first side gear, a second side gear, a spider, at least one pinion gear, and a case. The case encircles the first side gear and the spider and has an integral drive gear.

A downsized differential assembly having a simple structure, which can be mounted easily on automobiles. The differential assembly comprises a set of first to third gears arranged coaxially while being allowed to rotate relatively to one another. A first eccentric gear meshes with the first gear, a second eccentric gear meshes with the second gear, and a third eccentric gear meshes with the third gear, while being supported by an eccentric member in such a manner as to rotate around an eccentric axis which is offset from a rotational axis. Gear ratios between the first to third gears and the first to third eccentric gears are set to different values so that rotational speeds of the first gear and the second gear are reduced slower than that of the eccentric member.
