Abstract
A suspension means for mounting an instrument or the like which is susceptible to shock on a movable carrier, in particular a vehicle, comprises a flexible sealing means adapted to absorb shocks in at least one direction and further comprises a blocking device for rigid coupling of said instrument with said carrier, the blocking device being actuable by a drive means which works in said one direction against the resiliency of the sealing means.
Claims21
A suspension means for mounting on a movable carrier an instrument or the like which is susceptible to shock, said means comprising:
- flexible sealing means adapted to absorb shocks in at least one direction, said flexible sealing means including two coaxial, radially spaced rubber-elastic sealing rings which are biased between the annular surfaces of an inner ring connected with the instrument and an outer ring connected with the carrier, said inner and outer rings being disposed to radially define a fluid pressure cavity which controls the axial spacing of said sealing rings;
- and
- a blocking device adjustable against the resiliency of the sealing means in the axial direction for rigidly coupling the instrument with the carrier.
Vibration resistant mounting means comprising:
- an inner ring having a pair of radially outward facing surfaces;
- an outer ring axially spaced from said inner ring and having a pair of radially inward facing surfaces, one of said outward facing surfaces being radially outside of one of said inward facing surfaces;
- and
- a pair of resilient sealing rings disposed one each between a radially inward and a radially outward facing surface of said rings.
Vibration resistant mounting means comprising:
- an inner ring having a pair of radially outward facing surfaces;
- an outer ring axially spaced from said inner ring and having a pair of radially inward facing surfaces;
- a pair of resilient sealing rings disposed one each between a radially inward and radially outward facing surface of said rings;
- and
- means for selectively varying the axial spacing between said rings including means for pressurizing the cavity defined by the radially outward surface of said inner ring, the radially inward facing surface of said outer ring and said sealing rings.
Vibration resistant mounting means comprising:
- an inner ring having a pair of radially outward facing surfaces;
- an outer ring axially spaced from said inner ring and having a pair of radially inward facing surfaces;
- and
- a pair of resilient sealing rings disposed one each between a radially inward and a radially outward facing surface of said rings,
- said surfaces being generally parallel frustoconical surfaces whereby the likelihood of rolling contact between said surfaces and said sealing rings is enhanced.
A suspension means for mounting an instrument or the like which is susceptible to shock on a movable carrier, said means comprising:
- two coaxial, radially spaced rubber-elastic sealing rings biased between the annular surfaces of an inner ring connected with the instrument and an outer ring defining an anular cavity and connected with the movable carrier, said two sealing rings being adapted to absorb shocks in at least one direction and
- a blocking device comprising a servo drive means operatively communicating with said anular cavity to urge said inner and outer rings away from each other against the resiliency of said sealing rings in said at least one direction for rigidly coupling the instrument with said carrier.
A suspension means for mounting an instrument or the like which is susceptible to shock on a movable carrier, said means comprising:
- two coaxial, radially spaced rubber-elastic sealing rings biased between the annular surfaces of an inner ring connected with the instrument and an outer ring defining an anular cavity and connected with the movable carrier, said two sealing rings being adapted to absorb shocks in at least one direction and
- a blocking device comprising a servo drive means operatively communicating with said anular cavity to urge said inner and outer rings away from each other against the resiliency of said sealing rings in said at least one direction for rigidly coupling the instrument with said carrier,
- said blocking device further comprising adjustable stop pins equally spaced around the periphery of said inner ring for engagement with corresponding receiving elements in the outer ring assembly under the action of said servo drive means.
