摘要:
The actuator comprises a housing which has a longitudinal axis Z and in which an electric motor having a pinion is arranged. The pinion is in engagement in each case with at least one first gearwheel of a planetary gear, the first gearwheel forming, in each case together with a second gearwheel arranged directly adjacent, a uniform double gearwheel. One or more double gearwheels are arranged here. The first gearwheels run in a first toothed ring, which is connected fixedly to the housing. The respective second gearwheels run in a rotatably mounted, second toothed ring, which is connected to the part which is to be driven, with the number of teeth of the first toothed ring not being identical to the number of teeth of the second toothed ring. The invention furthermore relates to the use of the actuator for actuating a parking brake in a motor vehicle.

The invention relates to an electromechanically actuatable brake (2), comprising an electrically actuatable actuator (30) for applying the brake (2) in an application direction (42), which actuator (30) converts a rotary motion of a spindle (20) into a translational motion of an application element (26), in particular a piston, wherein the spindle (20) is driven by an electric motor (8), wherein a mechanical store for storing energy by twisting is provided, the first end of which store is coupled to the spindle (20) and the second end to a bracing element (80), wherein the store takes up energy during rotation of the spindle (20) in the application direction (42), by which energy the spindle (20) is rotated back against the application direction (42) in the currentless state of the electric motor (8), whereby the brake (2) is released.

A servo drive for activating a tailgate of a motor vehicle has a drive, a sun wheel driven by the drive and rotatably mounted on a first axle, and a planetary wheel rotatably mounted on a second axle. The sun wheel engages with the planetary wheel. The first and second axles have ends, are movably arranged at their ends facing away from the drive in a common web, and are spaced apart from one another by a constant distance. The planetary wheel engages in a ring gear segment which is fixedly connected to a bodywork, and an end of the web, which faces the ring gear segment, is movably connected to a connecting rod through a third axle. An end of the connecting rod facing away from the third axle is movably connected, via a fourth axle, to an output element which is connected by an end facing away from the fourth axle to the tailgate.
摘要:
A door-locking device having an inside door-handle element movable by an inside door handle. An outside door-handle element movable by an outside door handle. A driver element can be coupled in a form-fitting manner to the inside door-handle element and the outside door-handle element by a coupling. An authorization signal can be directed in a contact less manner to a control unit by a mobile authorization unit, and the outside door handle is assigned a switch by which, when the actuation of the outside door handle begins, a signal can be produced and directed to the control unit and when this signal and the authorization signal are present a drive can be activated by the control unit such that an uncoupling element can be driven to move from its uncoupled position into its coupled position by the drive.

A lock, particularly for the door of a motor vehicle, having lock elements including at least one lock element which can be connected by connecting elements to at least one manipulator. A coupling device is arranged in a force transmission path between the manipulator and the at least one lock element.
摘要:
A lock, suitable for use in a car door, has a rotary latch which cooperates with a locking wedge, or the like, and can be locked by a locking pawl in a locking position. The pawl is actuatable by a setting device for bringing the rotary latch at least into an open position. In order to provide a lock which is of improved efficiency and is both compact in construction and operates reliably, transmission elements are arranged between the pawl and the setting device for transmitting movement of the setting device, in stepped-down fashion, to the pawl.
摘要:
A closing device, in particular for vehicle doors or the like, having at least one manipulator which, with the interpositioning of a coupling device via connecting elements to a lock element can be driven by a setting drive, in particular a pawl when the setting device is activated, a transmission of force can take place from the at least one manipulator to the lock element over the coupling device which has a setting device.
摘要:
A lock including a device for unlocking the door of a motor vehicle in case of a malfunction of the lock, as in the event of an accident of the motor vehicle, to open the lock or allow the lock to be reliably opened manually. The unlocking is triggered by a setting device which can be operated during a malfunction independently of a supply of electric current for unlocking the door. Also included in the lock is a rotary latch for engaging a closure wedge upon a locking of the door, and a pawl which holds the latch in a locked position during normal locking of the door, but releasing the latch upon operation of the setting device in the event of a sensed malfunction.

A brake, in particular for motor vehicles, has a friction member (1) which can be pressed an actuator (15) against or released from the friction face of an element (3) which is to be braked. The brake is equipped with a particularly simple and reliable readjustment device (7) and with an emergency release device (12), wherein the readjustment device has a spindle (9) which drives an adjustable element (8) which is connected thereto, and the emergency release device (12) has two cam disks (13, 14) which are rotatable relative to one another, one (14) of which cam disks is rotationally fixedly connected to the spindle (9).
