Abstract:
A decoupling device for an electric motor in relation to a housing, comprising a motor mount that is connected to a motor housing of the electric motor and at least two decoupling elements made of elastic material, which extend along a longitudinal axis and coaxially to the axis and each of the at least two decoupling elements have a through opening with an interior wall, wherein each decoupling element (13) at least indirectly rests with a first contact point (22) against the motor mount (8) and rests with a second contact point (25) at least indirectly against the housing (9), the decoupling element is embodied as a decoupling bush (13) and, between the first contact point (22) and the second contact point (25), each decoupling bush (13) is secured so that the decoupling bush can be radially deflected in relation to the longitudinal axis (10), and at a first decoupling point (16) a circumferential retaining collar (20) is embodied on the motor mount (8) and at the first contact point (22) said retaining collar (20) protrudes into the through opening (14) of the decoupling bush (13) and rests against an interior wall (15), and a circumferential housing collar (19) is embodied on the housing (9), and at the second contact point (25), said housing collar (19) protrudes into the through opening (14) of the decoupling bush (13) and rests against the interior wall (15).
