Description
Technical field
Bus coating that the utility model is related to manufacture field, more specifically a kind of passenger car air-conditioner compressor assembly every
The mechanism shaken with belt stable operation.
Background technology
The compressor of air conditioner assembly of most of cars be usually by the drive devices such as engine drive, the compressor assembly with
Engine is by suspending after vibration isolation, on vehicle body side member, due to both occurring relative fortune relative to crossbeam after vibration isolation
Dynamic, therefore, centre-to-centre spacing will inevitably change, and the change of centre-to-centre spacing can produce incentive action to belt, often make skin
With occurring very big vibration, particularly in engine speed range, intrinsic frequency and engine, the compression of belt oscillation crosswise
The excitation coupling of machine, it may occur that resonate for several times, test is found, belt amplitude can reach tens millimeters during resonance, and resonance makes car
Internal vibration noise deteriorates, and riding comfort declines.Still further aspect, belt, which resonates, has also seriously endangered the longevity of belt
Life, influence belt reliability of operation, particularly stability, if belt turns over band problem, can stop compressor of air conditioner
Work, influences to take the passenger of car in torridity summer, reduces the comfortableness of car.
As shown in figure 1, in the passenger train plan of prior art, power assembly（1）Pass through engine belt pulley thereon（11）With
Belt（4）Drive compressor assembly（2）On transition belt pulley（23）Rotate, then by transition belt pulley（23）Drive compressor total
Into（2）On compressor pulley（21）And generator pulley（22）Rotate operation, the compressor assembly（2）The rotating shaft of bottom
（8）Limit the compressor assembly（2）It can only rotate around it, meanwhile, the compressor assembly（2）The screw rod of upper setting（9）One hinge
Connect installed in vehicle body side member（3）On, other end is provided with nut（91）, the nut（91）In screw rod（9）The upper vibration damping by setting
Spring（7）It is rotatable to screw regulation setting, by rotating the shock-absorbing spring（7）, then to compressor assembly（2）Installing plate（10）
Power is acted, compressor assembly is allowed（2）There is trend rotationally clockwise, by this method tightening belt（4）.It is another
Aspect, the rotating shaft（8）Outer surface be arranged with a ring-like rubber blanket（12）, pass through the ring-like rubber blanket（12）Shaken to isolate
It is dynamic.
The shortcoming of prior art passenger train plan：1. due to needing the requirement of holding flatness between belt pulley, it is undesirable to allow
Compressor assembly has swing, is considered based on stability, and the rigidity of ring-like rubber blanket only has the very big of design, makes deformation displacement pole
It is small, it is exactly almost rigidity, it is impossible to produce vibration isolating effect, or even amplify vibration；2. the main function of shock-absorbing spring is to carry herein
It is not isolation vibration for belt tension, because power assembly and compressor assembly are all that to be installed to vehicle body big by each suspending
Liang Shang, vibration can produce displacement during work, the length of belt is ensued change；3. in the structure, compressor
Assembly rotates around the axis, and excitation orientation of the motion in Belt Length direction and transverse direction is all important, easily encourages belt, makes skin
Band also vibrates；4. the belt has 2360N power when mounted, this power be present in power assembly and compressor assembly it
Between, for power assembly, it is not balanced, it can be acted on to a direction application, to dynamic assembly suspension
System has a negative impact, including suspension vibration isolation reduction, and suspending spacing gap and reducing even can encounter limited block, once encounter limit
Position block, the progress that the vibration of engine will not pass through decay is transmitted.
So, in the industry field that bus coating is manufactured, in order to coordinate the contradiction of each structure, it is necessary to develop one kind both
The requirement of vibration isolation can be met, the tensile force demand of belt and the stabilizing mechanism of belt operation can be met again.
