Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Below, the invention is explained in more detail with reference to two embodiments shown in a total of three figures. Shown are:

(2) FIG. 1 a longitudinal section through a device according to the invention shown here only schematically,

(3) FIG. 2 a variant of the device from FIG. 1, and

(4) FIG. 3 an individual part from FIG. 1.

DETAILED DESCRIPTION

(5) FIG. 1 shows a device for adjusting the height of a motor vehicle body 3. An actuator 1 sketched here only schematically is mounted on the vehicle body 3 with an elastomer support 2 in-between. A cut-out with a longitudinal carrier 20 and a rear-axle carrier 21 of the vehicle body 3 is sketched. The actuator is connected to a height-adjustable spring seat of a suspension spring 15 not shown here.

(6) A pin 4 for connecting the actuator 1 to the vehicle body 3 is provided that is guided with its actuator-side pin section 10 through a support eye 6 of a support plate 7 of the actuator 1. An elastomer part 8 of the elastomer support 2 is arranged on the vehicle body-side end of the support plate 7 between the support plate 7 and a flange 9 provided on the pin 4. Another elastomer part 22 of the elastomer support 2 is arranged on the actuator-side end of the support plate 7.

(7) The flange 9 is formed on its one end for supporting the elastomer part 8 of the elastomer support 2 and on its other end for supporting the pin 4 on the vehicle body 3. The pin 4 has an actuator-side and a vehicle body-side pin section 10, 11 each with a screw thread 13, 12, wherein the flange 9 is arranged between the two pin sections 10, 11.

(8) The support plate 7 is arranged between the flange 9 and a nut 14 screwed on the screw thread 13 of the actuator-side pin section 10. The elastomer part 22 of the elastomer support 2 is arranged between the nut 14 and the support plate 7.

(9) The pin 4 has a one-part construction with the pin sections 10, 11 connected rigidly to each other.

(10) FIG. 2 shows a variant of the device according to FIG. 1. The difference consists essentially in that the pin 4 has a two-part construction and only the elastomer part 8 of the elastomer support 2 is provided. A vehicle body-side pin part 16 carries the vehicle body-side pin section 11 with the screw thread 12 and an actuator-side pin part 17 carries the actuator-side pin section 10 with the screw thread 13. The two pin parts 16, 17 are guided so that they can move longitudinally one in the other. The flange 9 is connected rigidly to the vehicle body-side pin part 16.

(11) In the case of the first variant, the one-part pin 4 is arranged along the pin axis relative to the support plate 7. The elastomer parts 8, 22 arranged on both sides of the support plate 7 can be deformed elastically with these relative movements.

(12) In the case of the second variant, the support plate 7 is connected rigidly to the actuator-side pin part 17 of the pin 4. The elastomer support 8 arranged between the flange 9 and the support plate 7 can be elastically deformed with relative movements between the two pin parts 16, 17.

(13) The flange 9 of the pin 4 is formed in the two embodiments of the external hexagon head, in order to screw the pin 4 into a vehicle body-side threaded hole 18 formed in the longitudinal carrier 20 using a tool and thus to hold the device on the vehicle body 3.

(14) FIG. 3 shows the pin 4 described at the top of FIG. 1 as an individual part with the elastomer support 2. The elastomer parts 8, 22 are formed in both variants as washers.
