A fastening shackle for fastening a leaf spring to a vehicle body of a vehicle, comprising:
- a first bearing end configured to fasten to the vehicle body, the first bearing end comprising an outer sleeve, an inner sleeve and a plastic plain bearing, wherein the outer sleeve is shorter than the inner sleeve, and wherein the plastic plain bearing being slidably mounted in the outer sleeve, and the inner sleeve being affixed to the plastic plain bearing, wherein the sleeve-shaped plastic plain bearing comprises, on each side, one circumferential side collar that forms a lateral stop and delimits the outer sleeve laterally;
- a second bearing end configured to fasten to the leaf spring;
- and
- a shackle body connecting the first bearing end and the second bearing end, wherein the second bearing end comprises a leaf spring holder configured to secure the leaf spring, wherein the leaf spring holder comprises two holding limbs which delimit a receiving space configured to receive a leaf spring end of the leaf spring, wherein an outer wall of the outer sleeve is integral with the shackle body, and wherein an outer wall of the plastic plain bearing is moveably coupled to an inner wall of the outer sleeve.
A leaf spring arrangement comprising:
- a leaf spring comprising an end;
- and
- a fastening shackle comprising:
- a first bearing end, the first bearing end comprising an outer sleeve, an inner sleeve and a plastic plain bearing, wherein the outer sleeve is shorter than the inner sleeve, and wherein the plastic plain bearing being slidably mounted in the outer sleeve, and the inner sleeve being affixed to the plastic plain bearing, wherein the sleeve-shaped plastic plain bearing comprises, on each side, one circumferential side collar that forms a lateral stop and delimits the outer sleeve laterally;
- a second bearing end;
- and
- a shackle body connecting the first bearing end and the second bearing end;
- wherein the end of the leaf spring is rotatably mounted at the second bearing end of the fastening shackle, and the first bearing end of the fastening shackle is fastened to a vehicle body, wherein the second bearing end comprises a leaf spring holder configured to secure the leaf spring, wherein the leaf spring holder comprises two holding limbs which delimit a receiving space configured to receive a leaf spring end of the leaf spring, wherein an outer wall of the outer sleeve is integral with the shackle body, and wherein an outer wall of the plastic plain bearing is moveably coupled to an inner wall of the outer sleeve.
A method for producing a fastening shackle for fastening a leaf spring to a vehicle body of a vehicle, comprising:
- providing a basic shackle comprising a first bearing end with an outer sleeve, a second bearing end, and a shackle body connecting the first bearing end and the second bearing end, wherein the second bearing end comprises a leaf spring holder configured to secure the leaf spring, wherein the leaf spring holder comprises two holding limbs which delimit a receiving space configured to receive a leaf spring end;
- introducing an inner sleeve into the outer sleeve, wherein the outer sleeve is shorter than the inner sleeve;
- and
- injecting a plastic between an outer wall of the inner sleeve and an inner wall of the outer sleeve to produce a plastic plain bearing that is slidably mounted in the outer sleeve, wherein the sleeve-shaped plastic plain bearing comprises, on each side, one circumferential side collar that forms a lateral stop and delimits the outer sleeve laterally, wherein an outer wall of the outer sleeve is integral with the shackle body, and wherein an outer wall of the plastic plain bearing is moveably coupled to an inner wall of the outer sleeve.
