Embodiment Construction

[0029] exist figure 1 shows a cylindrical tube 1 for a shock absorber of a motor vehicle with a longitudinal extension axis A and a carrier spring 2 , wherein the carrier spring 2 surrounds the cylindrical tube 1 in the circumferential direction. The carrier spring 2 has a first end section 3 and a second end section 4 and is supported at least indirectly with the first end section 3 axially relative to the axis of longitudinal extension A of the cylindrical tube 1 (not shown here). on the supporting device of the outgoing motor vehicle. The support spring 2 is supported axially with the second end section 4 on the cylindrical tube 1 of the shock absorber.

[0030] Furthermore, it is shown in all figures that the cylindrical tube 1 has a spring retainer 5 which is formed integrally with the cylindrical tube 1 from the cylindrical tube 1 and which has a support surface 6 for carrying the end coil 7 of the spring 2 . In this case, the spring ring 5 can also be formed out of th...

Abstract

A vibration damper for a motor vehicle includes at least one cylinder tube with a longitudinal extension axis and a support spring, wherein the support spring has a first end portion and a second end portion, the support spring surrounds the cylinder tube in circumferential direction and is axially supported by the first end portion indirectly at a supporting device of the motor vehicle with respect to the longitudinal extension axis of the cylinder tube, and wherein the support spring is axially supported by its second end portion at the cylinder tube of the vibration damper. The cylinder tube has a spring disk which is formed integral with the cylinder tube, is formed out of the cylinder tube, and has a supporting surface for an end coil of the support spring.

Description

technical field [0001] The invention relates to a shock absorber for a motor vehicle according to the preamble of claim 1 . Background technique [0002] A shock absorber is known from DE 197 48 634 A1, which comprises a cylindrical tube and a load spring. The carrier spring has an upper first end section and a lower second end section. The support spring surrounds the cylindrical tube in the circumferential direction and is supported at least indirectly axially with the upper end section on the support device of the motor vehicle. The support spring is supported indirectly on the cylindrical tube with the lower end section. This support is achieved by means of a separate spring washer fastened to the cylindrical tube, which is supported axially on an annular bead formed from the cylindrical tube. [0003] Document DE 198 51 484 A1 discloses a shock absorber which also has a cylindrical tube with a longitudinally extending axis and a load spring, wherein the load spring h...
