WORK MACHINE AND CONTROL METHOD THEREOF
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.
VEHICLE DRIVE UNIT ASSEMBLY
A rear drive unit (RDU) for a vehicle includes a shift collar, a sleeve disposed around the shift collar, a planetary gear set, a differential including a side gear, and a locking plate configured to engage the side gear. The sleeve is configured to move the shift collar between a first position and a second position. The planetary gear set includes a sun gear and at least one planetary gear engaged with the sun gear. The sun gear is configured to engage the shift collar in the second position. The at least one planetary gear includes a pin extending through an entire length of the at least one planetary gear. The shift collar is configured to exert a force upon the locking plate via the pin to move the locking plate into engagement with the side gear in a third position.
ROTATABLE DRIVE AXLE ASSEMBLY FOR AN ELECTRIC VEHICLE
A rotatable drive axle assembly for an electric vehicle comprises a rotatable vehicle drive axle configured to be disposed along a transverse axis of an electric vehicle and having an axle end that is configured for attachment of a drive wheel. The rotatable drive axle assembly also comprises a selectively movable differential configured to be disposed on the rotatable vehicle drive axle and configured to operatively couple motive power of a selectively movable electric propulsion motor comprising a rotatable motor shaft rotatable about a motor axis to the rotatable vehicle drive axle and the drive wheel, the selectively movable electric propulsion motor and the motor axis configured to be oriented in a substantially vertical direction and movable with reference to the rotatable vehicle drive axle.
ELECTRIC VEHICLE COMPRISING A VERTICAL ELECTRIC PROPULSION MOTOR AND METHOD OF MAKING AND USING THE SAME
An electric vehicle comprises a vehicle chassis extending along a longitudinal axis and a rotatable vehicle drive axle disposed along a transverse axis and having opposed ends that are configured for attachment of a pair of opposed drive wheels. The electric vehicle also comprises a selectively movable electric propulsion motor comprising a rotatable motor shaft rotatable about a motor axis, the electric propulsion motor configured to be mounted within the vehicle chassis and operatively coupled to the rotatable vehicle drive axle and opposed drive wheels, the motor axis configured to be oriented in a substantially vertical direction.
ELECTRIC DRIVE MODULE CONFIGURED AS A BEAM AXLE
An electrically-operated electric drive module for use in a vehicle framework that is configured for a powertrain that includes an internal combustion engine. The electrically-operated electric drive module permits the vehicle to be converted to an electrically propelled vehicle in a manner that is cost-effective and which is relatively low in weight.
Hydraulic control unit with differential connection
A hydraulic control unit (HCU) assembly, for an electro-hydraulic limited slip differential system for a vehicle, includes a support bracket configured to couple to an underbody of the vehicle in a location remote from a live axle assembly of the vehicle, and an HCU including an integrated accumulator and reservoir assembly, a control valve assembly, and a motor and hydraulic pump assembly. The HCU is coupled to the support bracket.
Control of a limited slip differential based on a steering angle of a vehicle
A limited slip differential (LSD) transfers a torque from an engine to left and right wheels of a vehicle. A current angle of a steering device is determined. Rotational speeds of 5 the left and right driven wheels are also determined. A current wheel slip of is calculated as a difference between the rotational speeds of the left and right wheels. Maximum and minimum allowed wheel slips are calculated as a function of the current steering angle. The LSD is controlled so that the current wheel slip stays in a range between the maximum and minimum allowed wheel slips. To this end, the LSD is loaded if the wheel slip falls outside of the range 0 between the maximum and minimum allowed wheel slips.
Driving force transmission control apparatus
A control apparatus configured to control a driving force transmission apparatus. The control apparatus includes a torque command value calculator configured to calculate a torque command value for the right and left rear wheels based on a front-rear wheel rotation speed difference, a command value limiter configured to limit the torque command value to a value equal to or smaller than an upper limit value, and a current controller configured to control a current to be supplied to the driving force transmission apparatus so that a driving force determined based on the torque command value is transmitted to the right and left rear wheels. When the front-rear wheel rotation speed difference increases, the command value limiter sets the upper limit value smaller as a change amount of the front-rear wheel rotation speed difference per unit time increases.
VEHICLE FRAME ASSEMBLY
An assembly includes a vehicle frame having a crossmember defining a passage. The assembly includes a drive unit supported by the crossmember in the passage. The assembly includes a stabilizer fixed to the drive unit, the stabilizer permitting movement of the drive unit in a first direction relative to the passage and restricting movement of the drive unit in a second direction opposite the first direction.
ELECTRIC DRIVE MODULE WITH INDEPENDENT DRIVE UNITS HAVING FRICTION BRAKES THAT ARE SELECTIVELY ENGAGEABLE TO ONE ANOTHER
An electric drive module that includes a housing, a pair of drive units and a coupling unit. The drive units are disposed in the housing and each drive unit includes a motor unit and a friction brake. The motor unit has a stator, which is non-rotatably coupled to the housing, and a rotor that is rotatable about a motor axis and configured to drive a wheel of a vehicle. The friction brake has a first portion, which is non-rotatably coupled to the housing, and a second portion that is drivingly coupled to the rotor. The friction brake can be operated to create a rotational drag force that resists rotation of the second portion relative to the first portion. The coupling unit is configured to selectively rotatably couple the second portions of the friction brakes to one another.
