Abstract: A vehicle door checker integrated with a power drive unit for an automobile door includes a direct current permanent magnet electric motor subject to cogging torque. The electric motor includes a central shaft. The vehicle door checker also includes a cogging torque increase device that is mounted to the central shaft externally of the motor. The cogging torque increase device includes pairs of oppositely magnetized permanent magnets that are mounted coaxially in a stator and rotor respectively about the motor shaft. The stator magnets and the rotor magnets shift into and out of alignment with each other as the shaft is rotated such that the motor is held in multiple discrete stable positions that correspond to check positions of an automobile door.

CPC classification number: F16F9/3405 , F16F9/5126
Abstract: A hydraulic damper spool valve (15) includes a pair of resilient energy storage members (47, 49) one of which is disposed between each of a valve spool (39, 41) and a valve body dividing section (27) so as to bias the valve spools (39, 41) in opposing directions to the forces generated by the operating pressures in the hydraulic fluid of the hydraulic damper (1). The valve spools (39, 41) are configured to vary the hydraulic flow restriction between the upper portion (11) and the lower portion (13) of the hydraulic damper (1). A compression hydraulic flow path is structurally separate from a rebound hydraulic flow path to prevent backflow via the other hydraulic flow path during hydraulic flow in either direction, each said flow path communicating with only the at least one shaped aperture (35, 37) adjacent the opposing end of one of the valve sleeves (23, 25).

Abstract: A vehicle tailgate assembly comprises a frame with a transverse base and support arms extending perpendicularly therefrom adjacent distal ends of the base, a central section also extending perpendicularly from the base but to a lesser extent than the support arms, a door rotationally mounted to the frame between the support arms, the door being profiled with a central opening matching the central section and aligned therewith in a co-planar manner when the door is in a fully closed position, a mating portion comprising an indentation in the door adapted to mate with the central section when the door is rotated 180 degrees from the fully closed position to a working position to expose the central opening with the door co-planar with the frame.

Abstract: A door power drive module includes a housing and a motor arranged in the housing. First and second gearboxes are arranged in the housing and are coupled in series with one another by a shaft member. The first gearbox connects the motor to the second gearbox. An output shaft is coupled to the second gearbox. A brake assembly is selectively connected to the shaft member. The brake assembly has a normally closed position in which the shaft member is grounded to the housing. The brake assembly includes an open position corresponding to one of a door closing mode and a door opening mode. The shaft member is configured to be rotatable relative to the housing in the brake open position in response to the motor driving the first gearbox. The brake assembly includes a holding torque in the normally closed position. A torque is applied to the brake assembly above the holding torque that permits the shaft member to rotate in any direction of rotation. A position sensor is configured to detect rotation of the output shaft.

Abstract: A deployable vehicle rear wing conforms closely to the styled surface of the vehicle body in a retracted, or stowed, position while adaptively changing its cross section in a deployed position so as to provide a highly efficient airfoil section, with an integrated Gurney flap. Additionally, the adaptive cross section changes and Gurney flap deployment is provided via a linkage that utilizes a drive mechanism of a main deployment system.

Abstract: An automotive hinge assembly adapted to facilitate motion of a closure panel relative to a fixed body structure comprises a door component constructed from two press formed angle brackets structurally connected via a pivot pin and adapted to be mounted to a vehicle closure panel, a body component constructed from two press formed angle brackets structurally connected via a simple formed feature and the pivot pin and adapted to be mounted to a vehicle body structure, such that the pivot pin structurally assembles the two hinge components, facilitates relative rotary motion between them and structurally connects the multiple press formed angle brackets so that the resulting assembly achieves a much higher material efficiency than the prior art with an associated significant cost reduction.

Abstract: A power assisted automotive door system has a power drive module which includes an electric motor and integrated gearbox drive unit that provides a driving torque around the door's pivot axis. A controller is in communication with the electric motor, a torque sensor, a velocity sensor, and an accelerometer and processes measured and provided data and to predict a door torque using a real-time simulation. The controller commands the power drive module to produce a compensating torque that achieves a predetermined desired resistive door torque that corresponds to a desired door velocity in response to an operator's manual operation. The operator can move the door at any desired velocity only having to overcome the predetermined desired resistive door torque allowing the door to feel as if the vehicle is on flat and level ground.

Abstract: An automotive door system includes a hinge that supports a door. A switch provides a first input in response to a user request to automatically open or close the door. An output shaft of a power drive module is connected to the door and a gearbox to provide an output torque that corresponds to a desired motion of the door about the hinge. A brake assembly is connected to a shaft member and has a normally closed position in which the shaft member is grounded to the housing and an open position that corresponds to one of a door closing mode and a door opening mode. A position sensor detects rotation of the output shaft and provides a second input in response thereto, which corresponds to a manually initiated movement of the door that exceeds a slip torque of the brake assembly in the normally closed position.
