LINEAR DRIVE FOR A CLOSURE ELEMENT OF A MOTOR VEHICLE
The invention relates to a linear drive (100) for moving a closure element of a motor vehicle relative to a body of the motor vehicle. The linear drive (100) comprises an outer tube (110), an inner element (120) arranged in the outer tube (110), wherein the inner element (120) is telescopically extendable along a drive axis (A) of the linear drive (100) from an outlet end of the outer tube (110), and wherein an inner connecting element (128) for connecting the linear drive (100) to the closure element or to the body is fixed to the end of the inner element (120) which is extendable from the outer tube (110), a screw spring (130) arranged radially to the drive axis (A) between the inner element (120) and the outer tube (110), an inner support element (122) fixed to the inner element (120) axially to the drive axis (A), and an outer support element (111) fixed to the outer tube (110) axially to the drive axis (A), wherein the screw spring (130) is clamped axially to the drive axis (A) between the inner support element (122) and the outer support element (111). The linear drive (100) comprises a securing element (150) arranged between the screw spring (130) and the inner connecting element (128) and extending around the inner element (120) for securing the screw spring (130) against escaping from the linear drive (100), wherein, radially to the drive axis (A), an outer diameter of the securing element (150) is larger than an inner diameter of the screw spring (130), and an of the securing element (150) is smaller than an outer diameter of the inner connecting element (128), and wherein the inner element (120) is displaceable relative to the securing element (150) along the drive axis (A).
