Abstract
The invention relates to an expansion sleeve (10), the sleeve being configured to be arranged on an axle (110) to secure the axle in a hole (4), the sleeve comprising: a first and second section (20, 30) with a first and second outer diameter (D11, D2); wherein the first section has a conical shape with a tapering inner wall (22), and an outer wall (24) configured to abut an inner wall of the hole, the second section being configured to axially abut a fastening device (130) arranged at an end of the axle, wherein the second outer diameter is smaller than the first outer diameter, and wherein the second section comprises an inner wall (32) extending with an angle relative the axial direction (A) of the sleeve which is smaller than the angle (β) of the tapering inner wall of the first section.
Claims12
An expansion sleeve for a connection device, the expansion sleeve being configured to be arranged on an axle of the connection device to secure the axle in a hole, the expansion sleeve comprising:
- a first section with a first outer diameter;
- and
- a second section with a second outer diameter,
- wherein the first section has a conical shape with a tapering inner wall configured to abut a tapered section of the axle and an outer wall configured to abut an inner wall of the hole, the second section being configured to axially abut a fastening device arranged at an end of the axle wherein the second outer diameter of the second section is smaller than the first outer diameter of the first section, and wherein the second section comprises an inner wall extending with an angle relative the axial direction of the expansion sleeve which is smaller than the angle of the tapering inner wall of the first section.
A connection device for connecting two components, the connection device comprising:
- an axle;
- at least one fastening device arranged in connection with the axle;
- and
- at least one expansion sleeve, the expansion sleeve comprising:
- a first section with a first outer diameter;
- a second section with a second outer diameter,
- wherein the first section has a conical shape with a tapering inner wall configured to abut a tapered section of the axle, and an outer wall configured to abut an inner wall of the hole, the second section being configured to axially abut a fastening device arranged at an end of the axle, wherein the second outer diameter of the second section is smaller than the first outer diameter of the first section, and wherein the second section comprises an inner wall extending with an angle relative the axial direction of the expansion sleeve which is smaller than the angle of the tapering inner wall of the first section;
- and
- wherein the axle comprises at least one tapered section and is configured to be arranged with the at least one tapered section in a hole, wherein the at least one expansion sleeve is arranged over the tapered section, the at least one fastening device pressing axially against the expansion sleeve, such that the first section of the expansion sleeve expands and the outer wall of the first section presses against the inner wall of the hole.
A vehicle, comprising a connection device to connect two components of the vehicle, the connection device comprising:
- an axle;
- at least one fastening device arranged in connection with the axle;
- and
- at least one expansion sleeve, the expansion sleeve comprising:
- a first section with a first outer diameter;
- and
- a second section with a second outer diameter,
- wherein the first section has a conical shape with a tapering inner wall configured to abut a tapered section of the axle, and an outer wall configured to abut an inner wall of the hole, the second section being configured to axially abut a fastening device arranged at an end of the axle, wherein the second outer diameter of the second section is smaller than the first outer diameter of the first section, and wherein the second section comprises an inner wall extending with an angle relative the axial direction of the expansion sleeve which is smaller than the angle of the tapering inner wall of the first section;
- and
- wherein the axle comprises at least one tapered section and is configured to be arranged with the at least one tapered section in a hole, wherein the at least one expansion sleeve is arranged over the tapered section, the at least one fastening device pressing axially against the expansion sleeve, such that the first section of the expansion sleeve expands and the outer wall of the first section presses against the inner wall of the hole.
