Abstract:
Method for enabling characteristic drum shape determination for a motorized building door arrangement (6; 6'; 6'') having at least one door section (3; 3'; 3'') which is moveable between a closed position and an open position, and vice versa, a drive unit (1) having a motor (8) connected to a transmission (11) with at least one drum (4; 4'; 4'') having said shape for achieving a movement of said door section (3; 3'; 3''), and a control unit (24) adapted to control said drive unit (1), said method comprising the steps of giving said door section (3; 3'; 3'') at least one movement, determining a drive unit (1) movement corresponding to said door section (3; 3'; 3'') movement, and comparing said door section (3; 3'; 3'') movement and said drive unit (1) movement for determining the shape of said drum (4; 4'; 4''). The invention also relates to a drive unit (1) for a building door arrangement (6; 6'; 6'') and the use of the drive unit (1) in a building door arrangement (6; 6'; 6'').
Abstract:
According to the invention, a variable transmission is provided in the sense of an essentially constant load of the drive motor over the entire regulating distance, especially an increased transmission when arriving in the closed position, in order to increase the work load of the actuating drive motor (1) while providing an improved jamming prevention of a closing part. Said closing part is, in particular, a motor vehicle window pane (2) which can be displaced by a transmission, especially a cable drive drum (3 or 4). For this, the drive motor, for example, is not to be designed with regard to the maximal load when arriving in the closed position and, at the same time, a rapid jamming prevention is possible due to the slower speed when approaching the closed position.
Abstract:
A transmission assembly (138) for a powered sliding door system (22) for an automotive vehicle (24). The transmission assembly (138) includes a rotatably input member (152), a stationary hub (198), and a planetary gearset (210) disposed within the hub (198) and operatively cooperating with the input member (152). The transmission assembly (138) also includes an electromagnetic brake (268) disposed within the hub (198) and operatively cooperating with the planetary gearset (210) to lock and unlock a gear of the planetary gearset (210). The transmission assembly (138) further includes a rotatable output member (144) operatively cooperating with the planetary gearset (210).
Abstract:
A motor driven power door control system for a vehicle door includes a door position sensor that generates a door position signal for each predetermined distance of door movement so that the period of the door position signal is a measure of door speed. The motor control voltage is variably controlled to a controlled value to establish the door speed at a desired speed value. A door position signal period stall time is determined that is a predetermined function of the controlled value of the motor control voltage so that the stall time is adapted to the motor torque. An obstructive load is indicated when the period of the door position signal exceeds the stall time.
Abstract:
A vehicle (10) has a sliding door (14) mounted on rollers (22, 24 and 30) that are supported by and slidable in tracks (16, 18 and 20). A front cable (74) is attached to a front cable drive pulley, and extends from the pulley through a front cable roller guide assembly and is attached to a hinge and roller assembly (26) on the sliding door. A rear cable (100) is attached to a rear cable drive pulley (136) and extends from the pulley through a rear cable roller guide assembly and is attached to the hinge and roller assembly (26). The front and rear cable drive pulleys (136,144) each have a large diameter spiral cable groove (164), a small diameter cable groove (208) and a transition cable groove (210). A motor rotates the front and rear cable drive pulleys to move the sliding door. Fixed idler rollers (226,254) and spring biased idler rollers (228,256) guide the front and rear cables (74,100) to and from the cable drive pulleys (136,144) and are positioned relative to the cable drive pulleys to insure that the total cable in the continuous cable loop is substantially the same when the cables are driven by the small diameter cable groove (208) as when the cables are driven by the large diameter spiral cable groove (164).

Dispositif d'équilibrage pour volet arrière (1) de véhicule automobile, ledit volet étant articulé, à sa partie haute, à la structure (2) du véhicule autour d'un axe horizontal (3) et comprenant au moins un organe d'équilibrage tel qu'un ressort pneumatique (5) articulé d'une part à la structure (2), d'autre part au volet (1), caractérisé en ce que le ressort pneumatique (5) est articulé sur le volet (1) ou sur la structure (2), par l'intermédiaire d'un premier levier (9) sur lequel est articulée une première extrémité d'une biellette (12) dont la seconde extrémité est articulée sur un deuxième levier (15), en un point intermédiaire entre une articulation (16) dudit deuxième levier (15) sur le volet (1) (ou la structure) et un galet (17) coopérant, au voisinage de la position de fermeture du volet (1) avec la structure (2) ou avec le volet (1). Ce dispositif très simple présente une meilleure efficacité que les dispositifs connus, quelle que soit la configuration du volet (1).
