Set 40 is connected with subframe, is connected by bulb assembly 20 with knuckle or steering guiding mechanism.
Fig. 3 is the main structure diagram of rubber bushing in Fig. 1, and Fig. 4 is the facing structure signal of rubber bushing in Fig. 1
Figure, as shown in Figures 2 to 4, in the present embodiment, back bush 40 include bushing outer tube 41, bushing bushing pipe 42, rubber bushing 43 and
Inner sleeve 44, inner sleeve 44 are arranged in rubber bushing 43, and are vulcanized with rubber bushing 43 and connected, and rubber bushing 43 passes through interference
In bushing bushing pipe 42, bushing bushing pipe 42 is pressed in bushing outer tube 41 engagement sleeves.
Multiple endergonic structures 45 are provided with rubber bushing 43, each endergonic structure 45 includes two overflow launders 451 and connected
Connect the limited ring groove 452 of two overflow launders 451, overflow launder 451 and limited ring groove 452 run through up and down the two of rubber bushing 43
End, limited ring groove 452 are interior formed with close to the first side wall 4521 of the side of inner sleeve 44 and where bushing bushing pipe 42
The second sidewall 4522 of side, the multiple of the oriented place direction of the first side wall 4521 protrusion setting are formed in second sidewall 4522
Lug boss 453.
In the present embodiment, overflow launder 451 can absorb deformation caused by rubber bushing 43, yielding rubber bushing 43 by
Impact, when rubber bushing 43 produce deformation when, limited ring groove 452 can equally be compressed, the first side wall of limited ring groove 452
4521 can move to the direction where second sidewall 4522, when the first side wall 4521 of bushing bushing pipe 42 contacts with lug boss 453
When, lug boss 453 is compressed, now, the impact that yielding rubber bushing 43 is subject to together with overflow launder 451 of limited ring groove 452, when
When lug boss 453 is compressed to the limit, lug boss 453 can be supported to the first side wall 4521 of limited ring groove 452, prevent rubber
Glue bushing 43 is torn because deformation quantity is larger.Therefore endergonic structure 45 is set on rubber bushing 43, make lower swing arm total
Rubber bushing 43 in can bear larger pressure, improve the life-span of back bush 40, ensure the overall performance of vehicle.
Further, in the present embodiment, on edge on the section of the central shaft of rubber bushing 43, limited ring groove 452
The central point of center line and overflow launder 451 along its length direction is respectively positioned on using the central point of rubber bushing 43 as the same of the center of circle
On one circumference.
Further, in order to ensure the uniform of when the first side wall 4521 is contacting with lug boss 453 stress, in this implementation
In example, the shape of all lug bosses 453 is identical, and distance of the peak of lug boss 453 away from the central shaft of rubber bushing 43 is equal,
Namely each lug boss 453 can be by equal pressure when rubber bushing 43 deforms upon.It is multiple in the utility model
Lug boss 453 can collectively constitute zigzag or waveform.
Further, the endergonic structure 45 on rubber bushing 43 is two, and two endergonic structures 45 are on rubber bushing
43 axisymmetrical.
Fig. 5 is the side structure schematic view of bottom arm assembly provided by the utility model, and Fig. 6 is VI-VI directions in figure
Cross section structure schematic diagram, as shown in Figures 5 and 6, the diameter in the middle part of the inner chamber of inner sleeve 44 are more than the inner chamber Liang Ge ends of inner sleeve 44
Diameter, when bottom arm assembly is connected on subframe by connecting bolt through the inner chamber of inner sleeve 44, connecting bolt with it is interior
Two ends contacts of the inner chamber of sleeve pipe 44, and leave gap between the middle part of the inner chamber of inner sleeve 44 and connecting bolt.
When lower swing arm assembly produces relative to subframe to be rocked, acted between connecting bolt and rubber bushing 43
Power, when the intermolecular forces of connecting bolt and rubber bushing 43 are smaller, deformation caused by inner sleeve 44 is smaller, the inner chamber of inner sleeve 44
Middle part do not contacted with connecting bolt, the active force between connecting bolt and rubber bushing 43 is by the inner chamber of inner sleeve 44
Two ends are transmitted, and now, the contact area of inner sleeve 44 and connecting bolt is smaller, are advantageous to rubber bushing 43 and shape occurs
Become, mitigate the vibrations of vehicle；When the active force between connecting bolt and rubber bushing 43 is larger, deformation caused by inner sleeve 44
Larger, the middle part of the inner chamber of inner sleeve 44 can contact with connecting bolt, now, the contact area of inner sleeve 44 and connecting bolt compared with
Greatly, the deformation quantity of rubber bushing 43 can be efficiently reduced, prevents rubber bushing 43 to be torn because of larger deformation quantity.
More specifically, rubber bushing 43 includes body 431 and is formed at the both ends of body 431, and respectively to
Extension 432 away from the direction extension where body 431, the thickness of the side wall of extension 432 are less than the side wall of body 431
Thickness, the body 431 of rubber bushing 43 are arranged in bushing bushing pipe 42, and the extension 432 of rubber bushing 43 is from bushing bushing pipe
42 both ends are stretched out, and above-mentioned endergonic structure 45 is arranged on the body 431 of rubber bushing 43；The middle part of inner sleeve 44 and rubber
The body 431 of glue bushing 43 is corresponding, two ends of inner sleeve 44, two phases of extension 432 with rubber bushing 43 respectively
It is corresponding.
When lower swing arm assembly shakes relative to subframe, because the extension 432 of rubber bushing 43 equally can be right
Connecting bolt produces support force, therefore reduces the pressure suffered by the main part of rubber bushing 43, further prevents rubber bushing
43 are torn because producing larger deformation.
In summary, bottom arm assembly provided by the utility model, by being set on the rubber bushing 43 of back bush 40
Overflow launder 451 and limited ring groove 452, and lug boss 453 is set on limited ring groove 452, lug boss 453 and overflow launder can be made
451 jointly when rubber bushing 43 is smaller by impulsive force absorb rubber bushing 43 because by impulsive force and caused by deformation, and
Limited ring groove 452 can be made when rubber bushing 43 is larger by impulsive force, limitation rubber bushing 43 further deforms upon, and prevents
Only rubber bushing 43 is torn because deformation quantity is larger, thus the rubber bushing 43 in the bottom arm assembly can bear it is larger
Pressure, improve the life-span of back bush 40, ensure the overall performance of vehicle.
The utility model additionally provides a kind of vehicle, and the vehicle includes bottom arm assembly provided by the utility model, on
Other technical characteristics of the vehicle, refer to prior art, will not be repeated here.
