Abstract
A spindle drive for motor-actuated adjustment of an adjusting element includes a tubular spindle drive housing for a drive unit with a downstream spindle-spindle nut gear unit for generating a linear driving motion. A connection part inserted into one end of the drive housing is connected to an exterior socket via a damping arrangement comprising an elastic damping material. The connection part includes first and second flange-like end portions having confrontingly opposed, spaced apart front sides sandwiching the damping arrangement 4 which is connected to the end portion front sides by vulcanization and/or gluing. The socket is carried on the second end portion remote from the damping arrangement 4.
Claims10
In a spindle drive for motor-actuated adjustment of an adjusting element having a tubular spindle drive housing for a drive unit with a downstream spindle-spindle nut gear unit for generating a linear driving motion,
- a connection part for insertion into one end of the spindle drive housing, the connection part comprising a first flange end portion having a front side and a second flange end portion having a front side, the front sides of the first and second flange end portions being disposed in confronting opposition and spaced apart by a spacing;
- a damping arrangement comprising an elastic damping material disposed in said spacing between the first and second flange end portions and having a first end face connected to the front side of the first flange end portion and a second end face opposite the first end face and connected to the front side of the second flange end portion, said connections of the end faces of the elastic damping material to the first and second flange end portions being by one of vulcanization and gluing;
- and
- a socket carried on a second side of the second flange end portion remote from the connection of the second flange end portion to the damping arrangement,
- wherein the first and second flange end portions and the damping arrangement have a coaxial through-hole that leads from the second flange end portion via a connection aperture to outside of the spindle drive, for receiving a power supply cable and a control cable in guided relation through the connection aperture and through-hole to a drive unit of the spindle drive.
