Abstract
An engine mount for resiliently connecting an engine to a vehicle body. The engine mount has an isolator and a bracket. The isolator includes an inner tubular member, an outer tubular member, and a resilient member arranged between the inner and the outer tubular members. The outer tubular member is fixedly connected to the bracket, which is fixedly connected to the engine. The inner tubular member is fixedly connected to the vehicle body. A weight member is connected, at a position opposite to the position of connection of the outer tubular member to the bracket, to the outer tubular member via resilient members.
Claims6
An engine mount for connecting an engine to a vehicle body, the engine mount comprising:
- a bracket having a first surface for connecting the bracket to the engine in a cantilever fashion and a second surface;
- an outer rigid tubular member having an axis which is parallel to the second surface;
- a first connection means for fixedly connecting the outer rigid tubular member to the second surface of the bracket;
- an inner rigid tubular member which is concentric with respect to the outer rigid tubular member;
- a first resilient member of tubular shape fixedly arranged between the outer and the inner rigid tubular members;
- a second connection means for connecting the inner rigid tubular member to the vehicle body;
- and
- damping means connected to the outer rigid tubular member for achieving resonant frequencies of the mount outside of a predetermined frequency band corresponding to specified types of noises, wherein said damping means comprises a free weight member located at a position opposite to the first connection means and resilient means for connecting the free weight member only to the outer rigid tubular member.
