Die Erfindung betrifft eine Scharnier für eine Fahrzeugklappe, umfassend ein an einem von Fahrzeugrahmen und Fahrzeugklappe angeordnetes erstes Scharnierteil (2; 2'; 2"; 2'"), ein an dem anderen von Fahrzeugrahmen und Fahrzeugklappe angeordnetes zweites Scharnierteil (3; 3'; 3"; 3'"), wobei das erste Scharnierteil (2; 2J; 2"; 2'") und das zweite Scharnierteil (3; 3'; 3"; 3'") schwenkbar miteinander verbunden sind, einen Umlenkhebel (7; 7'; 7"; 7"') mit wenigstens einem ersten Gelenk (10; 10'; 10"; 10'") und einem zweiten Gelenk (13; 13'; 13"; 13'"), wobei der Umlenkhebel (7; 7'; 7"; 7'") mit dem zweiten Gelenk (13; 13'; 13"; 13'") an einem bezüglich des ersten Scharnierteils (2; 2'; 2"; 2'") beweglichen Teil schwenkbar angeordnet ist, und ein Federelement (11 ; 11'; 11"; 11 '"), das das erste Scharnierteil (2; 2'; 2"; 2'") und den Umlenkhebel (7; 7'; 7"; 7'") an dem ersten Gelenk (10; 10'; 10"; 10'") koppelt. Eine Scharnier, das ein sicheres und zuverlässiges Öffnen der Fahrzeugklappe ermöglicht, wird dadurch geschaffen, dass der Umlenkhebel (7; 7'; 7"; 7'") eine Abstützung (14; 14'; 14"; 14'") mit dem bezüglich des ersten Scharnierteils (2; 2'; 2"; 2'") beweglichen Teil aufweist.
Abstract:
Die Erfindung betrifft einen Türantrieb, bestehend aus mehreren Komponenten, wie mechanischen, hydraulischen und elektrischen Antriebsaggregaten und/oder einem oder mehreren Gehäusen (1, 2), wobei die Komponenten miteinander verbunden sind, und dass mindestens zwei Komponenten mit einer steck- oder drehbaren Kupplung (4) miteinander verbunden sind.
Abstract:
A vehicle closure hinge includes a mount having a pivot axis flange, a pivot link, a pivot coupling the pivot link to the pivot axis flange and a spring formed by a laterally coiled strand extending from a first coil end to a second coil end in a direction substantially perpendicular to the plane of displacement about the pivot axis. The coil size, the strand size and the number of coils can be varied as desired to vary the spring biasing force exerted against the vehicle closure without varying other components of the hinge. The hinge parts may be designed with various configurations including simple pivoting links or a four bar linkage. A strand end of the coil spring extends along the direction of the coil to a position at a first coil end to maintain biasing force near the plane of displacement about the pivot axis.
Abstract:
A power closing assembly operates a closure panel hingedly secured to a motor vehicle. The power closing assembly includes an actuator mounted to the motor vehicle, a movable striker also mounted to the motor vehicle to receive the closure panel's latch, and a rotary power cable connecting therebetween. The actuator has a closure cable on a spooling drum extending to the closure panel for closing from an open position when the actuator operates. The movable striker moves between a nominal inboard position and an outboard position. A rotary power cable connects between a provided output on the actuator and an input on the striker so that the striker's movement is powered and synchronized by the actuator. With the closure panel open, the actuator begins a closing cycle by driving in a direction to spool in the closure cable extending to the closure panel. The actuator's direction, using the rotary power cable, simultaneously causes the striker to move outboard. When the closure panel is pulled completely closed, the striker has also moved to its outboard position whereupon the closure panel's latch readily receives and engages the striker. Upon engagement the actuator reverses its drive direction. This reverse direction causes both the actuator to reset with respect to its closure cable spooling drum and the rotary power cable to turn in the other direction causing the striker to return to its inboard position and fully close the closure panel against its seal load.
Abstract:
A drive assembly moves a vehicle closure panel from an open to a closed condition. The drive assembly has a housing and a motor mounted on the housing. A drum and gear assembly is rotatably mounted on the housing. The drum and gear assembly has a drum having a helical groove, a gear in driving engagement with the motor, and a spring biasing the drum in a winding direction relative to the gear. The drum and gear have a lost motion connection therebetween. A cable has an end connected to the closure panel and an opposite end connected to the drum about the helical groove in the winding direction. The drum rotates in the winding direction relative to the stationary gear as the closure panel is manually moved from the open to the closed condition with the spring maintaining a cable tension. The drum and gear rotate together in the winding direction upon energizing the motor effecting powered movement of the closure panel to the closed condition. The motor is afterwards energized in an opposite direction counter-rotating the gear relative to the drum back to a start position.
Abstract:
An internal entrapment system for a garage door operator (30), comprising a motor, a pulse counter (62) for detecting a speed of the garage door (12), a potentiometer (56) for determining a plurality of positional locations of the garage door (12), and a control circuit (50) for calculating a motor torque value from the speed for each of said locations to compare with door profile data points, wherein said control circuit (50) takes corrective action if the difference between the motor torque value for each of said locations and said door profile data points exceeds a predetermined threshold, and otherwise updates said door profile data points to the motor torque values. In another embodiment both speed and position are detected by a slider element (58) which is connected to the control circuit (50). A closed loop lift cable system (100) may be employed.
Abstract:
The invention relates to a device for opening of doors. Electromechanical systems contain many expensive components and are thereby expensive to manufacture. Installed electromechanical systems are expensive in operation by virtue of the high and energy-demanding friction which always are present in mechanical constructions. The present operating device is less energy-demanding by the formed transmission of power via two piston-like parts (5 and 6). A driving device (2) is arranged to drive the piston-like part (5) and the second piston-like part (6) is connected to an operable element.
