A drive for a flap, wherein the drive has a housing, a motor and a spindle drive, wherein the motor and the spindle drive are drivingly connected to one another and make a motorized adjustment of the flap possible, wherein the drive moves the flap at least into an open position and a closed position, wherein the spindle drive has a threaded spindle with a nut and a thrust tube and the thrust tube is connected to the threaded spindle via the nut, wherein the thrust tube is moved via a translational movement, wherein the spindle drive is arranged inside a rotor and the motor drives the rotor, wherein the rotor is connected to the threaded spindle.

The invention relates to a control drive, in particular a spindle drive for adjusting a swivelable vehicle flap, comprising a housing (2), a spindle rod (3) that is rotatably mounted in the housing (2), a first coupling element (5) for driving a rotational movement of the spindle rod (3), and a torque-limiting device (6) arranged between the first coupling element (5) and the spindle rod (3) for limiting the torque transmitted from the first coupling element (5) to the spindle rod (3), comprising an adapter sleeve (8) arranged at a first end (3a) of the spindle rod (3) in a rotationally fixed manner, and a first tolerance element (13) arranged between the spindle rod (3) and the first coupling element (5). According to the invention, a control drive is provided, which is designed such that it is compact and can be economically produced, in such a way that the first tolerance element (13) is rotationally fixed to one of the first coupling element (5) and the adapter sleeve (8).

A power closure actuator for powering a movable closure includes a shaft situated between an electric motor and an output member. A brake device along the shaft is configured for actuation via an electric brake actuator to apply braking. An active brake clamp is movable by the electric brake actuator. An axially floating rotor is rotatable with the shaft and has a first axial side facing the active brake clamp a second axial side providing a second braking surface. A passive backing brake clamp is positioned adjacent the second braking surface. The axially floating rotor is biased away from the passive backing brake clamp by a first biasing member. Deflection of the first biasing member coupled with axial movement of the active brake clamp and the axially floating rotor enables braking by pinching action of the axially floating rotor between the active brake clamp and the passive backing brake clamp.

Drive apparatus for a closure element of a vehicle. The drive apparatus has a drive train with two drive sections, each having a drive connection. The drive sections are linearly movable with respect to each other in order to generate linear drive movements between the drive connections along a geometric axis between a retracted position and an extended position. An end stop is provided to limit the drive movement between the drive connections to the extended position, wherein the end stop has end stop faces movable toward each other on the drive sections and a damping device which, during a drive movement into the end stop, damps the drive movement in a manner which is dependent on its speed. The damping device has a damping element which, during the drive movement, is deformable by an axial impact of the end stop faces on each other or on an intermediate element.

A drivetrain for the motorized movement of a motor vehicle closure including at least one friction lock mechanism to provide a friction torque, the friction lock mechanism being part of a coupling mechanism of the drivetrain for coupling two drive components of the drivetrain for conjoint rotation, including a coupling piece on the motor side to a drive component on the motor side and via a coupling piece remote from the motor to a drive component remote from the motor, and including multiple friction lock elements which can be rotated about a drive axis, are situated coaxially to one another and form the friction lock mechanism, a middle one of the friction lock elements being concentric to one another and in frictional engagement with two others of the friction lock elements.

A transmission system with a protection device to enable access and damage control at a fare gate. The transmission system includes a motor, a gate paddle, and the protection device. The motor rotates a paddle shaft to drive the gate paddle. The gate paddle is operable to allow transmission through the fare gate. The protection device locks the paddle shaft in case of fare evasion at the fare gate. The protection device includes a locking mechanism integrated at the paddle shaft. The locking mechanism pulls shaft arms of the paddle shaft via a solenoid when torque applied to the paddle shaft reaches a preset threshold. The locking mechanism further locks the paddle shaft to stop rotation of the gate paddle and blocks transmission through the fare gate.
