Problems solved by technology

This customer-specific adaptation prescribes, in particular, differently configured housing covers, which often have to be designed individually and therefore differently, since the fixed positioning or orientation of the housing cover relative to the housing base body is seen on the vehicle. Depending on the assembly situation is not possible to achieve

Embodiment Construction

[0021] exist figure 1 A spindle drive 10 is shown in simplified form as part of a convenience drive 100 for seat adjustment of a seat 1 in a motor vehicle. The spindle drive 10 includes a drive motor 12 designed as an electric motor, which is connected to a multipart gear housing 14 . The transmission housing 14 has a receiving space 16 for rotatably receiving a drive element 18 , in particular designed as a worm gear. The drive element 18 interacts with a not shown drive element of the drive motor 12 , for this purpose a shaft protrudes from the drive motor 12 into the transmission housing 14 , the shaft resting on a dome-shaped protrusion 20 of the transmission housing 14 . In this region, it is supported in a manner known per se on the side facing away from the drive motor 12 . The drive element 18 is connected in a rotationally fixed manner with the main shaft 22, the main shaft is connected between two figure 1 In the region of the end-side housing cover, which is not ...

Abstract

The invention relates to a spindle driver (10). The spindle driver is provided with a transmission mechanism shell (14) connected with a driving motor (12). Wherein the transmission housing (14) has ahousing base body (30) for fastening to the drive motor (12), the spindle drive further comprises a receiving space (16) formed in the housing base body (30) for receiving the drive element (18), andconnecting surfaces (32, 34) arranged on opposite sides of the housing base body (30). The connecting surfaces are respectively provided with a hole pattern (45); the holes are used for connecting the housing base body (30) with the housing covers (36, 38) through fixing bolts (40). Wherein at least the receiving space (16) and the housing cover (36, 38) are penetrated by a spindle (22) connectedto the drive element (18), wherein the holes (45) are formed in the two connection surfaces (32, 34) of the housing base body (30) in a uniform manner, wherein the connecting surfaces (32, 34) are arranged perpendicular to the axis of rotation (26) of the spindle (22), and wherein the bore (45) has bores (42) for fastening the bolt (40) in the housing base body (30), said bores being arranged ata uniform angular distance relative to each other with respect to the axis of rotation (26) of the spindle (22).

Description

technical field [0001] The invention relates to a spindle drive and to a comfort drive with a spindle drive according to the invention. Background technique [0002] From DE 10 2016 203 639 A1 of the applicant, a spindle drive is known as part of a comfort drive for seat adjustment in a motor vehicle, which has a drive motor designed as an electric motor, which is connected to a transmission Mechanism housing connection. A drive element in the form of a worm wheel is rotatably mounted in the transmission housing, the worm wheel being arranged in operative connection with the drive motor or rotatable by the drive motor. The drive element is in turn connected in a rotationally fixed manner to the main shaft, which passes through the transmission housing and is connected to the main shaft nut outside the transmission housing. Due to the rotationally fixed arrangement of the spindle nut with respect to the axis of rotation of the spindle, a longitudinal movement of the spindle...
