Embodiment Construction

[0021] The screw drive shown in the drawing is used to electrically adjust the vehicle adjustment component 1 formed by the rear cover. But the proposed screw drive can be used for all possible automotive tuning components 1 . For example, rear lids, bonnets, side doors, charging compartment covers, roof windows or the like of motor vehicles may be mentioned here.

[0022] Along a geometric screw drive axis 2 , the screw drive has a substantially tubular screw drive housing 3 and two connections 4 , 5 for deriving the linear drive movement.

[0023] The screw drive housing 3 is here preferably constructed in two parts and consists of an upper housing part 3a and a lower housing part 3b. The two housing parts 3 a , 3 b are formed tubularly with an essentially circular cross section. The two housing parts 3 a , 3 b are moved telescopically relative to each other during screw drive adjustment in a known manner.

[0024] Here the two screw-driven joints 4, 5 are preferably each...

Abstract

A method for producing a spindle drive for an adjustable element of a vehicle, wherein the spindle drive has a substantially tubular spindle drive housing and two connections for diverting driving movements, wherein at least one connection of the spindle drive has a connection head which is connected to the spindle drive via a connection neck which is thinner than the connection head. A sealing cap for the spindle drive housing is provided with a sealing opening, in order to install the sealing cap, the sealing cap is pulled with the sealing opening thereof over the connection head of a connection of the spindle drive, and the peripheral region of the sealing opening is elastically deformed by the engagement with the connection head and is therefore widened, and that the peripheral region of the sealing opening is subsequently deformed back elastically in frictionally sealing engagement with the connection neck.

Description

technical field [0001] The invention relates to a method for producing a screw drive of an adjustment component of a motor vehicle according to the preamble of claim 1 and a screw drive according to the preamble of claim 5 . Background technique [0002] The mentioned screw drive can be used in all possible adjustment components in a motor vehicle. Examples include rear lids, tailgates, bonnets, side doors, charging compartment covers, roof windows or similar devices of automobiles. [0003] A screw drive is known (EP 1 862 628 A1) for adjusting the rear lid of a motor vehicle. The screw drive is arranged at the rain gutter part attached to the rear cover hole and has a two-body screw drive housing. The two housing parts move telescopically relative to each other when the adjusting screw is driven. The housing part is correspondingly designed to be tubular. [0004] Known screw drives have two joints for deriving the drive movement, which are each additionally coupled to...
