Abstract
A coupling for resilient interconnection of two objects, especially a wheel axle housing and a chassis of a vehicle. The coupling comprises an elongated supporting piece, which extends in a longitudinal direction and has two end attachment portions and a central portion. The coupling also comprises an elastic element, which is arranged around the central portion and has an approximately cylindrical outer surface and two end surfaces. The coupling further comprises a first and a second abutment member, where the first abutment member has a bottom and a tubular portion, which is fixed to the bottom and has an open end portion and a cylindrical inner surface. The bottom has a trough-going hole through which one end attachment portion can extend. The second abutment member has a hole through which the second end attachment portion can extend. The abutment members are arranged to be interconnected in order to enclose the element. According to the invention the second abutment member is designed in a similar manner to the first abutment member, end surfaces of the open end portions being arranged to abut against each other.
Description
- This application is a divisional of copending application Ser. No. 10/507,318 filed on Sep. 10, 2004, which is the National Phase entry of PCT International application no. PCT/NO03/00082 filed on Mar. 10, 2003, which claims priority to Norwegian application no. 20021215 filed on Mar. 12, 2002, the disclosures of which are expressly incorporated herein by reference.
- The invention relates to a coupling for resilient interconnection of two objects, especially a wheel axle housing and a chassis of a vehicle, comprising
- an internal coupling device comprising a supporting piece, which extends in an axial direction and has an axial supporting piece portion,
a rubber-elastic element, which is arranged round the supporting piece portion and has an axially extending outer surface and two substantially radially extending end surfaces, and
an external coupling device comprising two, approximately cup-shaped abutment members with a tubular wall portion and a bottom portion defining an inner portion of the abutment member, where each wall portion has an inner surface arranged to extend along and radially outside respective end portions of the outer surface of the element, the end of the wall portion facing away from the bottom has an end surface, and an inside of each bottom portion facing the inner portion of the abutment member are each arranged to abut against an end surface of the element for axial compression thereof, while the abutment members are pushed towards each other. - In U.S. Pat. No. 3,030,132 a coupling is disclosed where a body of a rubber-elastic material is cast between coupling devices or members during the actual assembly of the coupling. In order to ensure that the material is adequately compressed, during the casting process a recess is formed in the body while the cup members are kept at a correct distance apart. This is a laborious method, which is unsuitable for modern, fast serial production of vehicles. There is no indication of how a correct centering of the two cup members relative to each other is achieved during casting. A correct relative positioning of the cup members and the internal ball surface also seems to be important in order to ensure that the rubber-elastic material is not pinched between the cup members or that this material completely fills the space between the cup members and the
interior ball surface 1. This is also important to ensure that the coupling obtains the correct spring characteristic. - U.S. Pat. No. 6,231,264 illustrates a bearing device for a torque rod where an intermediate sleeve may be provided inside eyelets forming end portions of arms. In the intermediate sleeve is provided a bearing sleeve. The eyelets are not arranged to provide an axial compression of the bearing sleeve. The intermediate sleeve is only provided in order to create an axially fixed connection between the bearing sleeve and the eyelets, since the intermediate sleeve may be axially secured to the bearing sleeve on one side and on the other side to the eyelets via snap rings. The function of the intermediate sleeve is not for centering the eyelets or for counteracting the penetration of material of the bearing device between the eyelets, and it has a row of circular grooves that weaken it.
- In U.S. Pat. No. 5,649,719 an assembly is illustrated comprising a wheel axle housing and a chassis of a vehicle, and a coupling of the above-mentioned type for interconnecting the wheel axle housing and the chassis.
FIG. 1 is a perspective view of the assembly, where components have been separated from one another, andFIG. 2 illustrates a longitudinal section through the coupling. - As illustrated in
FIG. 1 , afirst end portion arms 2, 4 is each connected with alongitudinal frame beam 10 of a vehicle. Second end portions of eacharm 2, 4 converge at acoupling 12 located above and in front of awheel axle housing 14, connecting thearms 2, 4 to the wheel axle housing via abracket 16. - As illustrated in
FIG. 2 , thecoupling 12 comprises an internal coupling device with an elongated supportingpiece 20 withend attachment portions 22, 24 via which the supporting piece can be attached to the wheel axle housing, and acentral portion 26, which carries a rubber-elastic element 28. - The
element 28 is radially enclosed by an external coupling device, which is fixed to thearms 2, 4 and comprises afirst abutment member 30 with a bottom orshoulder 32, and asecond abutment member 34, provided in the form of a ring. Thisring 34 may be inserted in thefirst abutment member 30 and prevented from being moved out of it by means of asnap ring 36, which is arranged for insertion in a groove in thefirst abutment member 30. Theshoulder 32 and thering 34 are arranged to abut against respectiveopposite end portions element 28. In addition to thering 34, the known coupling comprises anadditional ring 42, which is arranged to abut against theshoulder 32, for extra support of theelement 28 axially, i.e. in the supporting piece's longitudinal direction. - During operation the coupling is influenced by substantial forces in its longitudinal direction as well as in its transverse direction. There is therefore a need for extremely strong and hence expensive rings, which may have to be forged from steel. When the coupling is assembled, the
element 28 is compressed axially by thering 34 being forced axially by means of a separate tool in the direction of theshoulder 30 or theadditional ring 42, whereupon thesnap ring 36 is inserted in the groove by expanding radially therein. Compression stresses are thereby advantageously created in the element. During this process it is vital for thesnap ring 36 to come into a correct engagement with the groove in order to ensure that thesnap ring 36 will not be forced out of the groove under the influence of the highly fluctuating stresses on thecoupling 12 during operation of the vehicle. - The object of the invention is to provide a coupling of the above-mentioned type, which is encumbered to a lesser extent by the above-mentioned drawbacks.
- A coupling for resilient interconnection of two objects, especially a wheel axle housing and a chassis of a vehicle is provided, comprising an internal coupling device comprising a supporting piece, which extends in an axial direction and has an axial supporting piece portion, a rubber-elastic element, which is arranged around the supporting piece portion and has an axially extending outer surface and two substantially radially extending end surfaces, and an external coupling device comprising two, approximately cup-shaped abutment members with a tubular wall portion and a bottom portion defining an inner portion of the abutment member, where each wall portion has an inner surface arranged to extend along and radially outside respective end portions of the outer surface of the element, the end of the wall portion facing away from the bottom has an end surface, and an inside of each bottom portion facing the inner portion of the abutment member are each arranged to abut against an end surface of the element for axial compression thereof, while the abutment members are pushed towards each other, characterized in that between the wall portions and the element an axially extending sleeve is mounted for relative centering of the abutment members and for counteracting the penetration of portions of the element between the end surfaces of the wall portions during the axial compression of the element.
