Drive, in particular spindle drive

A drive, in particular a spindle drive, for adjusting an adjustable element, in particular

• a flap, of a motor vehicle;
• the drive having a first drive connection and a second drive connection for coupling it to the motor vehicle;
• the drive comprising a drive train with two drive portions, which can be adjusted relative to one another, in particular linearly, along a geometric drive axis between a retracted position and an extended position and which comprise a plurality of train components which are coupled to one another to transmit force or torque so as to transmit a force introduced into the drive connections, each of the drive portions being assigned to one of the drive connections;
• the drive having a feed gear for carrying out in particular linear drive movements along the geometric drive axis;
• one of the two drive portions having a drive unit with a drive motor, downstream of which the feed gear is arranged;
• and,
• the drive motor having a motor shaft that has a geometric motor shaft axis and transmits a torque generated by the drive motor, and a bearing arrangement with at least one motor shaft bearing, which comprises a geometric bearing center axis and is configured to radially support the motor shaft, wherein the drive has a radial force introduction unit configured to act radially on the rotating motor shaft in the assembled state so that the motor shaft rests against one side of the motor shaft bearing in a defined position.
