Abstract:
A snubber apparatus comprises a casing defining an inner cavity. A shaft passes through the inner cavity and rotates about its longitudinal axis. The shaft has one or two ends laterally projecting out of the casing and being connected to a moving part of a tool to dampen given motions thereof. A wiper arm is on the shaft so as to rotate therewith the shaft, with a free end in close proximity to the surface portions of the inner cavity. The free end has an arcuate contour complementarily corresponding to a circumferential surface portion. A dam extends from the circumferential surface portion into close proximity to the wiper arm, to divide the inner cavity in two chambers, with movements of the wiper arm changing the volume of the chambers. A hydraulic circuit controls a flow of fluid between chambers to oppose a force to rotation of the shaft.
Abstract:
The present disclosure relates to a sliding door arrangement comprising at sliding door (1 ), the sliding motion of which is guided by a rail (7). A braking device (15) is attached to the door, and a collector device (17), attached to the rail. The braking device interacts with the collector device to brake the sliding motion of the door when the door approaches an end position. The collector device comprises a base portion (19), attached to the rail, and an arm portion (21 ) connected to the base portion by means of a hinge (23). A biasing spring (37) is connected to the base and arm portions to urge the arm portion towards the attachment surface, and an adjustment screw (41 ), attached to the arm portion (21 ), rests on the rail, such that adjusting the screw pivots the arm portion at the joint. This provides for an accurate adjustment of the collector device.

Vorrichtung 1 zur Unterstützung und Erleichterung des Öffnens und Schließens für einen Flügel 2 eines Fensters oder einer Tür 3, mit wenigstens einer zwischen einem Rahmen 4 und dem Flügel 2 des Fensters oder der Tür 3 zur Öffnungs- und Schließunterstützung wirkenden Federeinrichtung 5, die mit einer Ausstellschere 6 wirkverbunden ist, deren Öffnungsweite in einer Öffnungsendlage durch einen einerseits am Rahmen 4 und andererseits am Flügel 2 schwenkbeweglich angelenkten Ausstellelement oder Ausstellarm 7 begrenzbar ist, wobei der Ausstellarm 7 der Federeinrichtung 5 so zugeordnet ist, dass die Federeinrichtung 5 in Schließlage des Flügels 2 durch eine erste Längenänderung 8 derselben Energie speichert, beim Öffnen des Flügels 2 durch Längenänderung der Federeinrichtung 5 Energie freisetzt, um nach vollständiger Freigabe der Energie durch eine zweite Längenänderung 9, die entgegengesetzt zur ersten Längenänderung 8 wirksam ist, der Öffnung des Flügels 2 entgegen zu wirken, wobei die Federeinrichtung 5 dabei bis zur Erreichung einer Öffnungsendlage des Flügels 2 Energie speichernd aufnimmt.
Abstract:
The invention relates to a drive assembly for the motorized adjustment of an adjusting element (1) of a motor vehicle, wherein at least one drive (2) having an electrical drive motor (3), in particular a direct current motor, and a drive controller (5) associated with said drive (2) and connected to a supply (V), in particular a vehicle battery, having a supply voltage U v are provided, wherein said drive (2) is designed to not be self-locking, such that the drive motor (3) operates as a generator in the event of a non-motorized adjustment of the adjusting element (1) and creates a generator voltage U G , wherein the drive controller (5) has a drive unit (6) for supplying the at least one drive (2) with electric drive power. According to the invention, the drive controller (5) has a switching device (7) for switching the supply voltage (U v ) through to the driver unit (6) and a detecting device (8) for detecting a non-motorized adjustment of the adjusting element (1), and in the event of a predetermined, non-motorized adjustment of the adjusting element (1) being detected, the drive controller (5) switches the supply voltage (U v ) through to the supply terminals (9, 10) of the driver unit (6) in a switching operation by means of the switching device (7), such that the drive motor (3) acts on the supply (V) as a generator and is accordingly braked.
Abstract:
A brake device for a drivable part, in particular for use for a vehicle flap, in particular in an automobile, includes a drivable load device (11) which can be radially brought into contact with a disc (90) of the drivable part, with a first holding position and a second release position. At least one brake element rests against the periphery (92) of the disc (90) in a frictional manner in the holding position and secures the disc (90) from rotating using a specifiable force. In the release position, the at least one brake element is arranged at a distance from the periphery of the disc (90) and allows a free run of the disc (90), and the load device (11) can be adjusted between the holding position and the release position, preferably by a motor (12). A brake device or a rotating drive with which a drivable part of the drive is secured against a displacement on the basis of the mass of the component to be displaced even when the motor is not being provided with power or is deactivated is achieved in that the first holding position and the second release position are each designed as a metastable holding position.
Abstract:
A door brake system for braking and locking a hinged door of a motor vehicle includes a stop and a base body, which is moved relative to the stop via a swiveling motion of the door. The base body is hinged and/or detachably fastened to the door. The stop is arranged on the door frame or on a body of the motor vehicle. The base body is guided relative to the stop in a positive manner to improve an effect and/or the kinematics of the door brake system.

Abstract:
The invention relates to a drive arrangement for the motorized adjustment of an adjustment element of a vehicle, wherein at least one drive comprising an electric drive motor and a drive control means and is connected to a supply, wherein the drive is designed in a non-self-locking manner, the drive motor operates as a generator and generates a generator voltage, wherein the drive control means has a driver unit for supplying electrical power to the at least one drive. The invention proposes that the drive control means has a switching device and has a detection device for detecting a non-motorized adjustment of the adjustment element, and that the drive control means, when a predetermined, non-motorized adjustment of the adjustment element is detected, connects the supply voltage to the supply connections of the driver unit by means of the switching device in one switching operation.
