Spindle drive

A spindle drive for an adjustment element of a motor vehicle, the spindle drive comprising:

• a tubular drive housing including a first housing pipe;
• a spindle/spindle nut transmission including a spindle and a spindle nut, the spindle nut in meshing engagement with the spindle nut, the spindle/spindle nut transmission configured to produce linear drive movements along an axially extending geometric drive axis;
• a first drive connection;
• a second drive connection, the first drive connection and at least one of the spindle and the spindle nut forms a first drive train component, and the second drive connection and the other of the at least one of the spindle and the spindle nut forms a second drive train component, wherein the first and second drive connection are collectively configured to discharge the drive movements;
• a housing cover, the housing cover axially closes the drive housing in a region of the first drive connection and arranged in an axially secure manner relative to the first drive connection, wherein the first housing pipe is arranged in an axially secure manner relative to the first drive connection;
• and
• a housing collar, wherein the spindle drive includes a first coupling portion, in which the housing collar is materially bonded and connected to the first housing pipe, and a second coupling portion in which the housing collar is coupled to the housing cover in an axially secure manner;
• wherein the housing collar in the first coupling portion of the spindle drive is materially bonded and connected to the first housing pipe by a weld or an adhesive, and, in the first coupling portion of the spindle drive, the housing collar defines at least one receiving space configured to receive melt of the first housing pipe produced by welding, or adhesive which has been introduced during the assembly by means of an adhesive bonding operation.
