3, realize that by the lifting of control floating axle axle load shifts, improve the adhesion value on tire and road surface, be conducive to car load and drive.
The Chinese patent Granted publication number is CN202180722U, Granted publication day is that the utility model patent on April 4th, 2012 discloses a kind of Swing Arm Type Balanced Suspension trip shaft supporting construction, by the Fig. 2 in this document as can be known, this utility model comprises a connection shaft, a pair of connection shaft support and a pair of swing arm, each correspondence of the two ends of connection shaft is provided with a connection shaft support and a swing arm, after connection shaft passed its corresponding connection shaft support, corresponding with it again swing arm rotation cooperated.This utility model has following defective:
At first, connection shaft in this utility model is connected with the connection shaft support by rubber bush, the characteristic of expanding with heat and contract with cold of rubber bush causes between connection shaft, rubber bush, the connection shaft support and can't clamp, easily cause connection shaft in vehicle travels, to rotate, and then produce a large amount of heats on the two sides of rubber bush, make rubber bush burn out inefficacy thereby cause temperature to raise fast;
Secondly, the connection shaft in this utility model directly rotates with swing arm and cooperates, and not only road shocks directly can be passed on the vehicle through connection shaft, swing arm and adorn, and damages the vehicle facility, and easily connection shaft, swing arm is caused wearing and tearing, shortens the service life of parts.
Summary of the invention
The purpose of this utility model is to overcome the connection shaft that exists in the prior art easily to rotate, the defective of no protecting against shock and anti-wear facility and problem between connection shaft, the swing arm, provide a kind of connection shaft to be difficult for rotating, vibration damping anti-transition of the Swing Arm Type Balanced Suspension of protecting against shock and anti-wear facility is arranged between connection shaft, the swing arm.
For realizing above purpose, technical solution of the present utility model is: a kind of vibration damping anti-transition of Swing Arm Type Balanced Suspension, comprise swing arm, connection shaft and connection shaft support, described connection shaft cooperates with the swing arm rotation behind the connection shaft support, and connection shaft is positioned at the inside of connection shaft support, swing arm; Be interference fit between described connection shaft and the connection shaft support.
The position that is positioned at swing arm inside on the described connection shaft is arranged with rubber bush, and the outer cover of this rubber bush is provided with swing arm.
The position that is positioned at swing arm inside on the described connection shaft is arranged with the non-metal wear-resistant sleeve, and the outer cover of this non-metal wear-resistant sleeve is provided with rubber bush, and the outer cover of this rubber bush is provided with swing arm.
End away from the connection shaft support on the described connection shaft is connected with the middle part of thrust plate, and the sidepiece of thrust plate and the inwall of swing arm fasten.
Captive joint with connection shaft by bolt in the middle part of described thrust plate.
Be provided with dust protecting cap between described connection shaft support and the swing arm.
Compared with prior art, the beneficial effects of the utility model are:
1, be interference fit between the connection shaft in a kind of vibration damping of the utility model anti-transition of Swing Arm Type Balanced Suspension and the connection shaft support, and no longer cooperate through rubber bush, the defective of effectively having avoided rubber bush to expand with heat and contract with cold obviously, be difficult for holding tightly, simultaneously, connection shaft support, connection shaft are metal parts, expanding with heat and contract with cold of metal piece is very little, thereby both direct interference fit can prevent from rotating.Therefore, the connection shaft in the utility model is difficult for rotating.
2, the position that is positioned at swing arm inside on the connection shaft in a kind of vibration damping of the utility model anti-transition of Swing Arm Type Balanced Suspension is arranged with rubber bush; the outer cover of this rubber bush is provided with swing arm; during use; wear-resisting, buffer action that rubber bush rises; the road shocks that can decay and transmit through floating axle; effectively adorn on the protection vehicle, especially when also being provided with the non-metal wear-resistant sleeve between connection shaft and the rubber bush, wear-resisting, buffering effect is better.Therefore, the utility model is provided with protecting against shock and anti-wear facility between connection shaft, swing arm, can improve wear-resisting, buffering effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: swing arm 1, connection shaft 2, connection shaft support 3, rubber bush 4, non-metal wear-resistant sleeve 5, thrust plate 6, dust protecting cap 7.
The specific embodiment
Below in conjunction with description of drawings and the specific embodiment the utility model is described in further detail.
Referring to Fig. 1, a kind of vibration damping anti-transition of Swing Arm Type Balanced Suspension comprises swing arm 1, connection shaft 2 and connection shaft support 3, and described connection shaft 2 cooperates with swing arm 1 rotation behind connection shaft support 3, and connection shaft 2 is positioned at the inside of connection shaft support 3, swing arm 1; Be interference fit between described connection shaft 2 and the connection shaft support 3.
The position that is positioned at swing arm 1 inside on the described connection shaft 2 is arranged with rubber bush 4, and the outer cover of this rubber bush 4 is provided with swing arm 1.
