摘要: A control system for a vehicle (1) provided with a differential mechanism (3) that applies a torque difference to left and right wheels (5) and two electric motors (2) coupled to the differential mechanism (3), the control system including: two control units (11, 12) being connected to each other via high-speed communication means and each controlling one of the two electric motors (2); a first rotation speed sensor (26R) that detects a first rotation speed of a first electric motor (2R) of the two electric motors (2) and outputs the first rotation speed to the two control units (11, 12); a second rotation speed sensor (26L) that detects a second rotation speed of a second electric motor (2L) of the two electric motors (2) and outputs the second rotation speed to the two control units (11, 12); and a superordinate control unit (10) that calculates demanded torques of the two electric motors (2) based on vehicle information of the vehicle (1). At least a first control unit of the two control unites (11, 12) calculates two assigned torques to achieve the demanded torques calculated in the superordinate control unit (10) based on detection signals of the two rotation speed sensors (26R, 26L).

摘要: 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.

摘要: In one example, a hybrid drive unit comprises an electric motor, an axle differential for connection with a further motor, a first axle half shaft and a second axle half shaft connected to the axle differential, a first clutching device and a second clutching device. The electric motor is selectively drivingly engagable with the first axle half shaft via the first clutching device and with the second axle half shaft via the second clutching device.

摘要: The differential control device prohibits or limits a differential motion generated by the differential device. The sensor detects a turning angular velocity of the motor grader. Based on the turning angular velocity detected by the sensor, the controller controls the differential control device to perform the differential prohibition or limitation.

摘要: An actuator is used to longitudinally move a spline sleeve for controlling drive mode of a differential on an off-road vehicle. The actuator's motor rotates an eccentric knob through a drive train including intermediate gears and a worm gear. The eccentic knob is linked to the spline sleeve through a torsion spring carried on a pivot plate, with legs of the torsion spring pushing a slide block, transferring a moment provided by the eccentric knob into a linear slide force. The pivot plate and torsion spring are jointly mounted on the actuator housing by a hub, opposite the rotational axis of the eccentric knob from the slide block. The slide block includes a contact which completes a circuit through conductive pads on the actuator housing, so the position of the slide block can be directly sensed.

摘要: Various systems and techniques for providing enhancements to bogie-equipped vehicles are described and discussed. Such systems and techniques include, for example, actively driven bogie differentials, elevated obstacle mounting techniques, worm-drive steering, parking modes using toe-in or toe-out wheel steering, speed-sensitive steering mode selection, and various other enhancements and techniques.

摘要: An actuator assembly including a housing. The housing having an actuator component, an armature, and at least a portion of a sensor disposed therein. The armature is selectively positionable between a first position and a second position. The sensor includes at least one sensing element disposed within the housing adjacent to the armature. The sensing element has a physical property which varies based upon a position of the armature within the housing.

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: Systems and methods for an electric drive axle are provided. In one example, the electric drive axle may include an electric motor-generator rotationally coupled to a gearbox having a one-way clutch mounted on an output shaft and operable in an engaged configuration and a disengaged configuration, where in the engaged configuration, the one-way clutch transfers rotational energy from the output shaft to an output gear rotationally coupled to a plurality of drive wheels. The gearbox further includes a mode adjustment mechanism including a lock ring rotationally coupled to the output shaft and configured to selectively engage an input gear and the one-way clutch in a plurality of operating modes.

摘要: Disclosed is a travel control apparatus for a four-wheel drive vehicle in which the states of engagements between a drive output part for secondary drive wheels and left and right secondary drive wheel axles are each changed to a torque transmission state or a torque transmission interruption state. The ratio of rotational speed of the drive output part to the average of rotational speeds of primary drive wheels is greater than 1. When the engagement states corresponding to the secondary drive wheels on the outer and inner sides of a turning locus have been set to the torque transmission state and the torque transmission interruption state, respectively, the engagement state having been set to the torque transmission state is changed to the torque transmission interruption state upon determination that an accelerator pedal is not operated and the magnitude of lateral acceleration is equal to or greater than a predetermined threshold.
