Abstract
An air spring strut for a motor vehicle comprising an air spring with a shock damper for the spring-cushioning and damping of oscillations of a motor vehicle chassis, wherein the air spring comprises an air spring cover and a rolling piston, wherein a rolling bellows of elastomer material is clamped in an airtight manner between the air spring cover and the rolling piston, wherein the air spring cover comprises a damper bearing receptacle in which a damper bearing of the shock damper is arranged, and wherein the air spring cover comprises a clamping base to which a first end of the rolling bellows is attached, wherein at least the damper bearing receptacle of the air spring cover is produced from a plastic material.
Claims17
An air spring strut for a motor vehicle comprising:
- an air spring with a shock damper for spring-cushioning and damping of oscillations of a motor vehicle chassis;
- wherein the air spring comprises an air spring cover and a rolling piston, the air spring cover is produced in one piece and completely from the plastic material;
- wherein a rolling bellows of elastomer material is clamped in an airtight manner between the air spring cover and the rolling piston;
- wherein the air spring cover comprises a damper bearing receptacle in which a damper bearing of the shock damper is arranged, and wherein the air spring cover comprises a clamping base to which a first end of the rolling bellows is attached;
- wherein the damper bearing receptacle comprises an inner hollow cylindrical shoulder, wherein an inside diameter of the shoulder is less than the inside diameter of the damper bearing receptacle, with the result that the shoulder forms an annular stop, wherein the damper bearing lies on the annular stop;
- and
- wherein a plurality of bores is incorporated in the shoulder.
An air spring strut for a motor vehicle comprising:
- an air spring with a shock damper for spring-cushioning and damping of oscillations of a motor vehicle chassis;
- wherein the air spring comprises an air spring cover and a rolling piston;
- wherein a rolling bellows of elastomer material is clamped in an airtight manner between the air spring cover and the rolling piston;
- wherein the air spring cover comprises a damper bearing receptacle in which a damper bearing of the shock damper is arranged, and wherein the air spring cover comprises a clamping base to which a first end of the rolling bellows is attached;
- wherein at least the damper bearing receptacle of the air spring cover is produced from a plastic material;
- wherein the air spring cover comprises a plurality of receiving devices and a plurality of fasteners configured to attach the air spring strut to the motor vehicle, wherein one of the fasteners is at least partially engaged in a respective one of the receiving devices;
- and
- wherein the plurality of fasteners are at least partially overmolded with the plastic material of the air spring cover.
