A method for manufacturing a spring part includes the steps of providing a spring body with several spring windings made of a base material and coating the base material at least with a first protective layer. The method includes the step of applying a lubricant formed as a silicone-based lubricant to the outside of the coated spring body.

The present invention relates to a rotary drive (100) comprising: an output shaft (330); a motor (20), acting on the output shaft (330) via a downstream gear mechanism (30); an energy-store module with a linear line of action and with transmission elements (32, 326) to apply pressure circumferentially to an eccentric cam disk (331) arranged on the output shaft (330) for conjoint rotation therewith; and an intermediate shaft (320), being offset in relation said line of action and being provided between the motor (20) and the output shaft (330). The transmission elements (32, 326) comprise a roller lever (32), having a cam-follower roller (326) spaced apart from the intermediate shaft (320), wherein the cam-follower roller (326), pressed circumferentially against the eccentric cam disk (331), interacts with the output shaft (330). The energy-store module is arranged on the motor side in relation to the intermediate shaft (320).

The disclosure relates to a drive arrangement for movement of a tailgate, wherein at least one drive unit is provided, having two drive connections, wherein a first drive unit is motor and spring-operated and has a drive unit motor as well as a drive unit spring, respectively acting on the two drive connections associated with the first drive unit, wherein the first drive unit comprises a movement sensor, representing movement information regarding a movement between the drive connections, wherein a second drive unit is spring-operated and has a drive unit spring, acting on the two drive connections associated with the second drive unit, wherein a drive unit controller is provided, which detects a predetermined deviation of the sensor signal of the movement sensor from a predetermined normal signal corresponding to the normal condition as an error condition and upon detecting an error condition carries out an error routine.

The present invention relates to a method, a swing door system and a swing door operator (10) for moving a swing door leaf (20) between a closed and an open position (C, O), the swing door operator (10) comprising at least one drive unit (100), a control unit (200) and a sensor (300), the control unit (200) is operatively connected to the drive unit (100) and to the sensor (300) and configured to regulate the drive unit (100) to move the swing door leaf (20) between the closed and open position (C, O), wherein the sensor (300) is configured to identify an object (30) in a safety volume (400) in front of a first side (21) of the swing door leaf (20), the safety volume (400) comprising a first volume (401) and a second volume (402).

The disclosure discloses a driving device for door opening and closing, which includes: a box body; a permanent magnet synchronous motor arranged inside the box body, an output shaft of the permanent magnet synchronous motor extending along a vertical direction; and a gear set arranged inside the box body and connected with the output shaft of the permanent magnet synchronous motor, and a gear at a tail end of the gear set is provided with a connecting rotating shaft that extends along a vertical direction and is used for connecting a door panel. The above driving device for door opening and closing uses the permanent magnet synchronous motor as a driving source, which is matched with the gear set to implement transmission, the door panel is driven to rotate by the connecting rotating shaft on the gear at the tail end of the gear set.

A flap assembly for a vehicle includes a flap, which by way of a linear actuator drive is pivotably drivable about a pivot axis from a closed position to an opened position. The drive includes a spring assembly that acts in a supporting manner on the flap. The actuator drive has an actuator housing that has one end articulated on the body of the vehicle, and an actuator rod being deployable from the other end of the housing. An external end of the actuator rod is articulated on the flap at a radial spacing from the pivot axis. The spring assembly is releasably disposed on the other end of the housing and has a compression spring supported by the actuator housing. The compression spring acts on the flap between a closed position and an initial opening angle of the flap.

A door control system is provided. The control system includes a controller configured to control a door via a motor. The motor is powered by a battery and bypasses the controller via relays and/or switches when power to the controller is disconnected. The current of the motor may be monitored and/or displayed to confirm that the door is balanced.
