Abstract: Methods and systems are provided for an electric axle. The electric axle system includes, in one example, an electric machine and a multi-speed transmission that is rotationally coupled to the electric machine and rotationally coupled to two output shafts. The transmission includes a differential rotationally coupled and positioned coaxial to a mode planetary gear set. In the electric axle system, the mode planetary gear set is a meshed planet compound planetary gear set and a mode clutch in the transmission is configured to selectively shift the mode planetary gear set between a first mode and a second mode.

Abstract: A front-rear wheel driving force distribution device includes a center differential and a limited slip differential. The limited slip differential includes a first clutch, a second clutch, a first piston, a second piston, and a one-way clutch provided between the first clutch and a rear propeller shaft. If the second clutch is engaged by the second piston, the propeller shaft on the rear side rotates at increased speed as compared with a case where the first clutch is engaged by the first piston. The one-way clutch couples the first clutch and the rear propeller shaft if a number of rotations of the first clutch is same as or higher than a number of rotations of the rear propeller shaft, and idles if the number of rotations of the first clutch is lower than the number of rotations of the rear propeller shaft.

Abstract: A differential for a vehicle. The differential includes a cage, which is rotatable about a first axis of rotation and has a drive interface, a first driven gear, mounted in the cage to be rotatable about the first axis of rotation, a second driven gear, mounted in the cage to be rotatable about the first axis of rotation, a compensating gear, which is mounted in the cage about a second axis of rotation extending perpendicularly to the first axis of rotation and meshes with the first and the second driven gear, a flywheel mass, coupled to the cage and locked against rotation with respect to the first axis of rotation and displaceable in a radial direction perpendicularly to the first axis of rotation, and a clutch, which, as a result of an outward movement of the flywheel mass in the radial direction, is movable into a locking state.

Abstract: Cable-actuated differential enabling N degrees of freedom provided by a plurality of pulleys and at least N+1 tensioning cables. The cable-actuated differential increases a dynamic force range by minimizing co-activation of the tensioning cables at any operating point. A cable-actuated differential having three cables provides motor based control of a 2 DOF joint that can be applied to robots or teleoperation. A cable-actuated mechanical differential having opposing bevel gears and a middle bevel gear meshed with the opposing gear allows an output connector to controllably and independently rotate about the x axis or y axis via three operational modes without backlash.

Abstract: A method for determining, in real-time, an electronic limited-slip differential (eLSD) clutch torque includes receiving vehicle data in real-time, wherein the vehicle data includes a torque request, determining a preliminary eLSD clutch torque using a neural network and the vehicle data, determining clutch torque bounds of the eLSD using a physics-based model, determining whether the preliminary eLSD clutch torque is outside the clutch torque bounds of the eLSD, adjusting the preliminary eLSD clutch torque using clutch torque bounds to determine a final clutch torque of the eLSD in response to determining that the preliminary eLSD clutch torque is outside the clutch torque bounds of the eLSD, and commanding, in real-time, the eLSD to apply the final clutch torque to a clutch of the eLSD.

Abstract: A handcart may include a chassis unit and a container unit configured to be detachably attached to the chassis unit. The chassis unit may include a front wheel unit rotatably supporting a front wheel; a rear wheel unit rotatably supporting a rear wheel; a chassis frame extending in a front-rear direction and supporting the front and rear wheel units; and a prime mover configured to rotate at least one of the front wheel and the rear wheel as a drive wheel. The container unit may be selected from a group including at least a first container unit and a second container unit. The first container unit may include a first container and a first container frame extending in the front-rear direction and supporting the first container. The second container unit may include a second container and a second container frame extending in the front-rear direction and supporting the second container.

Abstract: 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.

Abstract: 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.

Abstract: 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.
