A drive device, in particular for an adjustable vehicle flap, comprising includes a housing extending axially along a drive axle, a motor for generating a driving force in the direction of the drive axle, a first drive element, and a coupling device arranged between the motor and the first drive element. The coupling device comprises a coupling housing and at least one first coupling part with a coupling section for coupling to the first drive element. The first drive element is coupled to the coupling device via the coupling section of the first coupling part, and a braking device for braking a drive movement of the first drive element. A drive device, in particular for an adjustable vehicle flap, which has a lower residual installation length and can thus be used more flexibly in various installation space situations is created by the braking device being arranged axially in the coupling section of the first coupling part.

A brake arrangement for a drive apparatus, in particular for a drive apparatus for adjusting a vehicle flap, includes a brake housing (2), wherein the brake housing (2) comprises a first brake housing part (3) and a second brake housing part (7), a first brake element (13) which is arranged non-rotatably in the brake housing (2), a second brake element (15) which is arranged rotatably in the brake housing (2), and a preload means (19) for preloading one of the first brake element (13) and second brake element (15) toward the other of the first brake element (13) and second brake element (15) in the direction of a longitudinal axis (L) of the brake housing (2). The brake housing (2) has a connecting section (11) for connecting the first brake housing part (3) and the second brake housing part (7), and in that the first brake housing part (3) and the second brake housing part (7) are welded to one another in the connecting section (11).

A hinge has two arms that can be pivoted relative to one another between a closed initial position and a second position. A first arm has a first guide slide. A second guide slide can be shifted along the pivot axis and can contact the first guide slide. When the two arms are moved towards the initial position, at least one cylinder-piston unit can be loaded by means of the second guide slide. The second guide slide can be rotationally fixedly coupled to the second arm in a first pivoting angle sub-range bordering the initial position and to the first arm in a second pivoting angle sub-range bordering the second position. The hinge has a first control slide rigidly connected to the second arm and a second control slide that makes contact with the first control slide and that is coupled against rotation to the first guide slide.

A hinge includes a leaf unit, first and second action units and an axle unit. The leaf unit includes first and second leaves that are rotatable relative to each other. The first leaf has a first barrel. The second leaf has a second barrel. The first and second action units are co-rotatable with the first leaf. The axle unit includes a fixing member mounted in the second barrel and co-rotatable with the second leaf, and first and second axle constituents respectively associated with the first and second action units and co-rotatable with the fixing member.

A device to be installed in any type of door, be it of glass, wood, aluminum or steel, in order to allow its automatic and controlled opening or closing, with minimum effort. The configuration 10 consists of a cap 20 and a wrapper 30, having in the inner part of the wrapper a plate-type spring 40, a fixed drum cam 50 and a movable drum cam 60. If the mechanical spring is installed in the center of the door, it can be rotated 360 degrees with displacement points at 90 degrees and 270 degrees and stop points at 180 degrees and 360 degrees.

A torsion washer of the present disclosure includes a base portion and an elastic unit extended from the base portion. The elastic unit includes an external elastic arm and a torsion-adjusting arm arranged inside the external elastic arm. A space surrounded by the base portion and the external elastic arm is divided into a hole and a slot, in air communication with the hole, by using the torsion-adjusting arm. A distance, i.e., a radius, between the external elastic arm and a center of the hole is larger than a distance, i.e., an interference distance, between the torsion-adjusting arm and the center of the hole. Moreover, the present disclosure provides a torsion device including a plurality of the torsion washers and a shaft coupling through the holes of the torsion washers, and the shaft is configured to selectively contact each torsion-adjusting arm.
