Spindle drive
The invention relates to a spindle drive for a valve (2) of a motor vehicle, comprising a motor drive arrangement (6), comprising a spindle gear mechanism (7) drivingly connected downstream of the motor drive arrangement (6), and comprising two drive connections (8, 9) for transmitting drive movements. The spindle gear mechanism (7) has a spindle (10) which can be rotated by the motor drive arrangement (6) and a spindle nut (11) which is engaged with the spindle in a rotationally fixed manner. The spindle nut (11) carries out an axial retraction movement (12), in which the distance between the two drive connections (8, 9) is reduced, and an axial extension movement (8, 9), in which the distance between the two drive connections (7, 8) is increased, according to the rotational direction of the spindle (10). The spindle nut thread (11a) extends beyond the spindle thread (10a) in the direction of the retraction movement (12) at least in the fully retracted position and surrounds at least one part of the motor drive arrangement (6).
