Specific implementation mode
As shown in Figure 1, to use the embodiment of the vehicle of damping frame in the utility model:Vehicle includes vehicle frame, in vehicle
It is provided in frame to compressor of air conditioner 11, compressor of air conditioner 11 is connected with engine 12 by belt pulley, and is set on vehicle frame
There is the damping frame that vibration damping is carried out to compressor of air conditioner 11.Damping frame includes the bearing 1 for carrying compressor of air conditioner 11.Branch
Seat 1 is inverted triangle structure, and the middle part of bearing 1 is hinged with rotation seat, and bearing 1 can be rotated around rotation seat.Rotation seat includes U-shaped
The peripheral surface of skeleton, skeleton is enclosed with rubber pad 10, filled with the supporting block 8 for capableing of absorbing vibration damping in skeleton, in rotation seat
It is interior equipped with through-hole and the shaft 13 that is plugged in through-hole, axle sleeve 9 is equipped between shaft 13 and the through-hole of rotation seat.
The both sides of bearing 1 are provided with the identical pneumatic support seat of structure, pneumatic support seat includes the spring being vertically arranged
Cylinder 3, be provided in spring strut 3 with spring strut 3 be oriented to cooperation piston rod 2, piston rod 2 can pushing tow bearing 1, piston rod 2
3 inner space of spring strut is separated into a rod chamber and rodless cavity by the piston of lower part, and the bottom lock of rodless cavity becomes
One space that can be connected to pressure medium.The top of spring strut 3 is provided with inward flange, inward flange can be with the work of piston rod
Beyond the Great Wall end face block coordinate, so that the stroke of piston rod is restricted, spring strut 3 be additionally provided with to the piston on piston rod 2 into
The spring 4 of row pushing tow.It is connected with gas bag 6 in the bottom of spring strut 3, gas bag 6 can be that sufficient air source is provided in spring strut 3,
Piston rod 2 is driven to be moved up and down in spring strut 3.Control gas path on-off is provided in the gas circuit that gas bag 6 is connect with spring strut 3
Switch 7, the barometer 5 of atmospheric pressure value in capable of showing gas circuit is provided between the external interface of switch 7 and spring strut 3.
In technical staff using the damping frame in the utility model come when compressor of air conditioner is adjusted, damping frame
In supporting block 8 and rubber pad 10 can reduce the vibration that compressor of air conditioner 11 is transmitted on vehicle frame, and to branch in damping frame
There are two different working conditions for the tool of piston rod 2 that seat 1 is supported, and can absorb air-conditioning pressure in unpressurized spring 4
The vibration that contracting machine 11 generates, piston rod 2 can receive pressure and push upward pushing tow bearing 1, can increase what damping frame was applicable in
Range.When the vibration of horizontal direction and vertical direction occurs in compressor of air conditioner 11, the rotation of bearing 1, bearing 1 can be caused to rotate
The vibration that a part of vertical direction can be balanced out, the vibration being transmitted on piston rod 2 by bearing 1 can drive piston rod 2 to act, this
When piston rod 2 be in servo-actuated state, can be tension or in compression.Piston rod 2 action drive 4 deformation of spring, 4 deformation of spring by this
It is converted into mechanical energy and interior energy, reduces the vibration that bearing transmits outward.
When the idling of vehicle changes, 11 He of compressor of air conditioner is transmitted in engine 12 suffered by damping frame
The vibration frequency that compressor of air conditioner 11 itself generates can change, when intrinsic frequency of the driving frequency close to damping frame,
Damping frame can resonate with compressor of air conditioner 11, therefore technical staff carrys out regulating piston bar when damping frame is shaken
2, piston rod 2 is pushed using air pressure to carry out rigid support to the bearing 1 in damping frame.

Spring cylinder 3 coordinates preferably, and a pressure space can be provided for gas, and the air pressure of 3 lower half of spring strut at this time is got higher, and air pressure pushes
Piston moves up, 2 upward pushing tow bearing 1 of piston rod, and bearing 1 is vibrated when rotating down, can be by the support of piston rod 2
Power makes the rigidity of bearing 1 get higher.So that the intrinsic frequency of entire damping frame is changed by changing the rigidity of bearing 1, keeps away
Exempt from damping frame to resonate with compressor of air conditioner 11, the vibration of compressor of air conditioner 11 is passed on vehicle frame.
If satisfied effectiveness in vibration suppression cannot still be obtained by reaching maximum to the air pressure being filled in spring strut 3, technical staff can be with
It turns off the switch, deflates to the gas of rodless cavity in spring strut 3, the survival gas and spring 4 in spring strut 3 can integrate work
With ejector piston, until reaching satisfied vibrating effect, then the air pressure including spring strut 3 is constant, enables piston rod 2
It keeps acting on the rigid support of bearing 1, technical staff can observe the reading of barometer 5 to keep the air pressure of spring strut 3.
In other embodiments, the spring in spring strut may be replaced by other forms, such as spring is provided as
With the tension spring of piston rod cooperation, it can equally play and cushioning effect is played to the vibration of compressor of air conditioner, realize vibration and noise reducing
Purpose.
In other embodiments, spring can also be not provided in spring strut, gas has compressibility, can be to air conditioner compressed
Damping action is played in the vibration of machine.
In other embodiments, the upper surface of cylinder can also be not provided with inward flange, directly be set as uncovered structure, opening knot
There is no the air pressure for generating resistance is moved up to piston rod in structure.
In other embodiments, air pressure regulator may be replaced by other forms, such as be directly disposed as inflation/deflation
Connector is directly inflated when needing to be pressurized pressure chamber, when needing to depressurize or adjust, is directly deflated to realize control piston
Support situation of the bar to bearing.
