Abstract
An engine mount device includes a housing, a carrier within a cavity in the housing, and a flexure flexibly connecting the carrier to the housing, with a pin disposed in a hole in the carrier to support an engine. A method of providing isolation in the engine mount device includes transmitting a force from the pin into the carrier; mechanically isolating the carrier from the housing via the flexure; and providing, via the flexure, a higher stiffness in one or more radial directions of the hole compared to a stiffness provided in an axial direction of the hole.
Claims52
An engine mount device comprising:
- a housing;
- a carrier that is at least partially inside the housing, the carrier comprising a hole through at least a partial thickness of the carrier, the hole being configured to receive a trunnion pin;
- and
- at least one flexure connecting the carrier to the housing,
- wherein the at least one flexure has a stiffness in one or more radial directions of the hole that is at least double to a stiffness in an axial direction of the hole,
- wherein the housing and/or the carrier comprise one or more snubbing surfaces configured to limit a deflection of the carrier relative to the housing.
In an engine mount device comprising:
- a housing, a carrier within the housing, and
- at least one flexure flexibly connecting the carrier to the housing, with a trunnion pin being disposed in a hole in the carrier to support an engine,
- a method of providing isolation in the engine mount device, the method comprising:
- transmitting a force from the trunnion pin into the carrier;
- mechanically isolating the carrier from the housing via the at least one flexure;
- and
- providing, via the at least one flexure, a higher stiffness in one or more radial direction of the hole compared to a stiffness provided in an axial direction of the hole, and
- limiting a deflection of the carrier relative to the housing by forming one or more snubbing surfaces in the housing and/or the carrier.
