  • Publication number: 20230108973
    Abstract: A spring part, in particular for a driving device, includes a spring body extending around a central axis. The spring body comprises several spring windings which run radially around a spring axis and are made of at least a base material. The base material is surrounded at least by a first protective layer, and the spring body is at least partially covered on the outside by a lubricant. 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.

  • Publication number: 20230041203
    Abstract: 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.

  • Patent number: 6934999
    Abstract: A double-armed hinge for use in a motor vehicle, includes a first bar for fastening to a front bonnet of said motor vehicle, a second bar for fastening to a body of said motor vehicle, a first arm, a second arm, and a thrust piece. At least one of said first arm and said second arm is constructed in two parts and includes a first strut and a second strut. The thrust piece thrust piece is applied to one of said first strut and said second strut. The thrust piece includes a head configured to grip behind the first or second strut. The first and second struts are pivotably connected to each other by a connecting joint and rigidly braced to each other by a connection device. The connecting device yields under a given load so that, under a sudden load that exceeds the given load, the connection device breaks and the first and second bars come closer to each other substantially without resistance.
