Coupling

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.
