Control of a limited slip differential based on an engine torque
A limited slip differential (LSD) is mounted on a driven axle of a vehicle to drive left and right wheels. To control the LSD, a current input torque applied to the LSD is determined and a predicted engine torque is determined based on an accelerator control position. A current average speed of the left and right wheels is also determined. A preload is applied to the LSD. The preload is determined based on the predicted engine torque and to the current average speed of the left and right wheels.
Electric actuator and rotation control mechanism
This disclosure provides an electric actuator and a rotation control mechanism. The electric actuator includes: a motor; a speed reduction mechanism; an output part; and a rotation detection device. The output part extends in an axial direction and is disposed on one side in the axial direction with respect to a motor shaft of the motor. The rotation detection device has: a magnet that is fixed to the output part and extends in a circumferential direction of the output part; and a rotation sensor that faces the magnet in the axial direction or in a radial direction. The magnet has multiple magnetic poles disposed in the circumferential direction. At least one magnetic pole of the magnet is disposed at a predetermined angular position with respect to an angle reference position of the output part in a rotation direction.
Motorized disconnect system and operation methods
Methods and systems are provided for a motorized disconnect operable to selectively engage and disengage two rotating components of a vehicle drivetrain. As one example, a motorized disconnect system is provided that operates via an electric motor and includes a shifter assembly with an oscillating gear track and cam profile for rotating the shifter assembly while moving it in an axial direction to selectively couple two rotating components.
Bicycle telescopic apparatus
A bicycle telescopic apparatus includes a first tube, a second tube, an actuating member, and a hydraulic positioning structure. The first tube defines an axial direction. The second tube is telescopically received in the first tube in the axial direction. The actuating member is movable relative to the first tube in the axial direction of the first tube. The actuating member is configured to move the second tube relative to the first tube in the axial direction. The hydraulic positioning structure is configured to position the first tube and the second tube relative to each other in the axial direction.
CONTROL OF A LIMITED SLIP DIFFERENTIAL BASED ON AN ENGINE TORQUE
A limited slip differential (LSD) is mounted on a driven axle of a vehicle to drive left and right wheels. To control the LSD, a current input torque applied to the LSD is determined and a predicted engine torque is determined based on an accelerator control position. A current average speed of the left and right wheels is also determined. A preload is applied to the LSD. The preload is determined based on the predicted engine torque and to the current average speed of the left and right wheels.
Locking transfer case
A transfer case comprises a primary output shaft, and a secondary output shaft selectively coupleable to the primary output shaft with a plate clutch to transfer torque therebetween. The plate clutch includes a housing, a plurality of interleaved plates that are engaged alternatingly with the primary output shaft and the housing to rotate therewith, and an apply plate non-selectively coupled to the primary output shaft to rotate therewith. The apply plate is moveable axially along the primary output shaft into a first configuration in which the apply plate is positively coupled to the housing to rotate therewith, a second configuration in which the apply plate rotates independent of the housing, and a third configuration in which the apply plate compresses the interleaved plates to form a friction coupling between the primary output shaft and the housing.
REFUELINIG CONTROL SYSTEM FOR INTERNAL COMBUSTION ENGINE
A refueling control system for an internal combustion engine includes a fuel tank; a vapor pipe; a step motor-driven shut-off valve; a fuel filler lid; and an electronic control unit configured to, when the fuel filler lid is to be opened, i) drive the shut-off valve such that the shut-off valve is opened, ii) close the fuel filler lid when an opening degree of the shut-off valve is less than a set opening degree, and iii) open the fuel filler lid when the opening degree of the shut-off valve is greater than or equal to the set opening degree. The electronic control unit sets the set opening degree such that the set opening degree when an opening speed of the shut-off valve is low is greater than the set opening degree when the opening speed of the shut-off valve is high.
ELECTRO-MECHANICAL ON DEMAND (EMOD) TRANSFER CASE - DUAL DRIVE GEAR AND SHIFT FORK CONSOLIDATION
A dual drive gear of an actuation assembly for a transfer case includes an annular disk, a dual drive gear hub, and a sense plate. The annular disk has an inner periphery and an outer periphery. The outer periphery defines a plurality of teeth projecting radially outward. The dual drive gear hub is attached to the inner periphery of the annular disk and has an inner surface that defines a bore extending through a center of the dual drive gear. The dual drive gear hub includes a pair of curved walls projecting from a first axial end face of the annular disk. The sense plate projects from a second axial end face of the annular disk opposite of the first axial end face and includes a plurality of curved wall sections. The annular disk, the dual drive gear hub, and the sense plate are formed together as a single piece.
STEPPER DRIVEN VALVE FOR CONTROLLING FLUID COMMUNICATION BETWEEN A FUEL TANK AND A CANISTER
A fuel system having a fuel tank, a filler pipe for adding liquid fuel, a carbon canister for collecting fuel vapors from the fuel tank during a refueling operation, a stepper motor and a stepper driven valve for controlling fluid communication between the fuel tank and the canister, where the valve is configured to be positionable in a closed position, an open position creating a passageway with a first size, and one or more intermediate positions each creating a passageway with a size which is smaller than the first size and having a moving element, movable relative to a valve opening between a closed position and an opened position, the moving element having: a sealing means for making a leak tight seal and, a deflecting means for controlling the fluid flow, where the deflecting means protrudes inside the valve opening and is adapted to be located upstream relative to sealing means.
Motorized disconnect system and operation methods
Methods and systems are provided for a motorized disconnect operable to selectively engage and disengage two rotating components of a vehicle drivetrain. As one example, a motorized disconnect system is provided that operates via an electric motor and includes a shifter assembly with an oscillating gear track and cam profile for rotating the shifter assembly while moving it in an axial direction to selectively couple two rotating components.
