Abstract:
An automatically opening/closing apparatus for vehicle of rack-and-pinion type is reduced in size and weight. The automatically opening/closing apparatus for vehicle is automatically opened/closed, by transmitting rotation of an electric motor to a back door through a drive power transmitting mechanism comprising a pinion and a rack. The rack is supported linearly reciprocably by a slide mechanism comprising a slide block and a guide rail. The slide block is formed to be sufficiently short to the entire length of the rack and the guide rail is accordingly formed to be short. Further, the rack is provided with a groove portion, and a holding member contacting with a holding face is disposed in the groove portion. Then, an interval between the rack and the opinion is maintained by the holding member, whereby engagement of the pinion therewith is ensured.
Abstract:
The invention concerns a command and release device for an electrical actuator for swing gates, that includes a transmission joint comprised of a coupling with frontal teeth (20,21) inserted between the output shaft of gear motor and a worm screw (14) and a release element (24). This element is associated in a radial way to the said coupling so that it can be manually released in an emergency. The release element is comprises an eccentric pin that engages the coupling element in a radial way that can be moved from an engagement position to a release position by being turned by a lock barrel (26) with its key.
Abstract:
An activating mechanism is provided for use with a four-link hinge of the type typically used for closure of a vehicle movable deck, such as a trunk lid or engine compartment hood. A lower link bracket is secured to the vehicle body and an upper link bracket is secured to the movable deck. Pivoting links may be connected between the upper and lower link brackets.
Abstract:
A drivable flap hinge for connecting a flaps such as a front hood or a trunk lid, to a body of an automobile in an articulated manner. The drivable hinge includes a first retaining part for fixing to the flap, a second retaining part for fixing to the body, at least one connecting member, which is pivotably arranged on at least one of the two retaining parts with a joint, and a driving motor, which is drive-connected to a joint pin of the joint. The flap hinge advantageously enables a front gate or tail gate of an automobile to pivot in a driven manner as a result of the driven joint pin connecting the first retaining part and the connection member.
Abstract:
A drive unit for a power operated vehicle closure has a track, a guide moveable along the track, a link attached to the guide at one end and adapted to be attached to the vehicle closure at the opposite end, and a motor assembly for moving the guide along the track. The motor assembly has an electric motor and a speed reducer driven by the electric motor that has a first stage and a second stage. The first stage includes a belt drive and the second stage is a spur gear set. Alternatively the first stage is a worm gear and a mating helical gear. The worm gear preferably has a high lead angle and a high number of leads. The speed of the electric motor is reduced to about 1000 rpm or less in the first stage permitting the use of spur gears in the second stage while retaining quiet operation.
Abstract:
A base plate has mutually opposed first and second side surfaces. A first group of parts are arranged on the first side surface, which includes an electric motor, a speed reduction unit and an electromagnetic clutch. The speed reduction unit has a gear member which is projected to the second side surface from the first side surface through an opening formed in the base plate and driven by the motor when the electromagnetic clutch assumes ON condition. A second group of parts are arranged on the second side surface, which includes an intermediate gear which is rotatably connected to the base plate and meshed with the gear member, an output gear which is rotatably connected to the base plate through a shaft secured to the output gear and meshed with the intermediate gear and an output arm which is connected to the output gear to rotate therewith. The output arm is connected to the lid through a link.
Abstract:
An actuating system includes a driving device fixed to a base part and operatively connected to a movable part. A sensor detects the rotational speed of the movable part at a reference measuring location, and a control system forms a differential of the rotational speed with respect to the time. The formed differential is compared in a comparison unit with a stored differential value which corresponds to a measuring point on a route of movement of the movable part. An obstacle is recognized when there is a difference above a threshold value between the formed differential and the associated stored value.
Abstract:
A magneto-rheological clutch assembly for use in an electromechanical system. The clutch assembly includes a motor having a shaft that is coupled to a magneto-rheological clutch. There is also included a gear plate that is attached to the clutch, as well as being connected to a contact plate and pinion gear. The pinion gear engages a corresponding connection of a power operator system. The magneto-rheological clutch prevents damage to the motor power operator system and panel by simulating a slipping condition when a load exceeding a specified tolerance is applied to the panel.
Abstract:
A device for a braked movement of furniture doors in particular with a horizontal rotation axis comprises two attachment pieces (11, 12, 211, 212, 311, 312, 411, 412) that are movable in opposite directions around a common rotation axis (13, 213, 313, 413) in a free manner in one rotation direction and against a resisting force of a friction joint in the other rotation direction. Between an attachment piece and the friction joint the device comprises a first surface (28, 228, 328, 428) and a second surface (27, 227, 327, 427) facing each other to delimit a space therebetween in which a wedging element (26, 226, 326, 426) is disposed. The extension of the facing surfaces and/or the shape of the wedging element between them are of such a nature that the wedging element tends to fixedly fit between said facing surfaces causing them to rotate integrally with each other when rotation of the two attachment pieces takes place in the direction that must involve a braked movement.
Abstract:
A power closure system (40) for a vehicle panel (22, 24) includes position initialization techniques that ensure accurate position initialization. According to this invention, any slack in a coupling (62) between the vehicle panel and a motor (42) for moving the vehicle panel is removed prior to obtaining an initialization position reading when the panel (22, 24) is in a closed position. The inventive arrangement also includes determining a desired torque at which to operate the motor (42) during a position initialization procedure.
