Abstract: A pedestrian protection automotive hood hinge comprises a release assembly which comprises a retainer supported by one of a first member and a second member and a releasable pin supported by the other of the one of the first and second members. The releasable pin is captured in the retainer in the normally closed position and the normally opened position. An actuator is configured to engage the second member and move the second member upward relative to the first member in response to a collision input. The releasable pin is configured to be released by the retainer in response to the collision input permitting the second member to pivot about a member pin relative to the first member to an opened hood collision position. A retention link with a retention pin moves in a controlled manner during a collision so that the retention pin engages a retention slot. At maximum opening of the hood, the retention pin engages a retention clip adjacent the retention slot and begins to rebound. With continued force exerted by the hood on the retention clip, the retention pin passes through and exits the retention clip and the hood decelerates to a final post collision position.

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.

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: 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.

Abstract: A twist beam is manufactured from a tube and has a shorter sectional perimeter in the “V” or “U” shape center section and a longer sectional perimeter at the beam ends. The present disclosure therefore proposes to use a tubular member having a predetermined length. The tubular member is deformed at the center section of the tube into a “V” or “U” shape and then expanded at both end portions. This structure is formed using a closed die internal pressure forming process such as hydro-forming or blow molding or the like. The ends of the tubular member may also have a substantially oval or rectangular section. The tubular member of the present disclosure may also be heat treated in the closed die internal forming process to achieve a higher material strength. In this manner, the twist beam of the present disclosure is optimized to used the smallest possible section along its entire length, thus has a substantially lower mass and can be manufactured using less material and therefore at a substantially lower cost.

Abstract translation: 扭梁由管制造，并且在“V”形或“U”形中心部分具有较短的截面周长，而在梁端部具有较长的截面周长。 因此，本发明提出使用具有预定长度的管状构件。 管状构件在管的中心部分处变形为“V”或“U”形，然后在两个端部处膨胀。 这种结构使用诸如液压成型或吹塑成型等的封闭模具内压成形方法形成。 管状构件的端部也可以具有基本上椭圆形或矩形的部分。 本公开的管状构件也可以在封闭模具内部成形工艺中进行热处理，以获得更高的材料强度。 以这种方式，本公开的扭梁被优化以沿着其整个长度使用尽可能小的部分，因此具有基本上较低的质量，并且可以使用较少的材料制造，因此以显着较低的成本。

Abstract: An auxiliary hydraulic system for vehicles, in particular pick-up trucks, is configured to supply hydraulic fluid under pressure to both on-board and off-board auxiliary equipment such as snow plows, dump boxes and wood splitters. The auxiliary hydraulic system includes a multi-piston fluid pump with electrically selectable poppet valves and an associated microprocessor control that facilitates variable output so that a desired proportional flow can be supplied to the auxiliary equipment. The system also provides a switchable valve arrangement for directional control and an arrangement of fluid distribution pipes and detachable couplings so that a range of different auxiliary equipment can be quickly and simply connected to the system. A simple user interface is also included so that the operator can command the auxiliary equipment from either within or in close proximity to the vehicle.
