Arm.
Second counter-jib 52 includes：Forward horizontal stand arm section 521 and rear balance arm section 522.The He of forward horizontal stand arm section 521
Balance arm section 522 misplaces connection along the horizontal plane of vehicle-body width direction afterwards, and has a lap；Wherein, rear balance
Arm section 522 is towards the unilateral biasing L1=90mm~175mm of vehicle frame center line L0, so that the second light plate spring 32 and rear steel
Flat spring 41 biases to vehicle frame center line L0, realizes the second light plate spring 32 and the outer space of rear spring 41
Expand.
The widening structure of second middle spring bracket 63 is engaged the connection that can make both it with the structure of the second counter-jib 52
It is more stable.
In actual use, the width of each leaf spring can also be the other sizes in addition to 90mm, and it is according to reality
The model and adaptation conditions of border trailer determine；The rear balance arm section 522 of second counter-jib 52 is unilateral towards vehicle frame center line L0
The scope of biasing, it can also be determined according to the leaf spring width of actual selection, or according to different trailer vehicles and matching requirements
It is determined that it is not construed as limiting herein.
Further, the suspension 100 of the present embodiment also includes shaft connector (not shown), for by steel plate
Spring is connected to the axletree of trailer.The shaft connector includes：Bridge welding assembly, leaf spring is connected to bridge welding assembly
U bolt and the torque arm link for torque arm to be connected to bridge welding assembly front end.
The suspension 100 of the present embodiment trailer, on the whole in the narrow structure in the wide rear end in front end.In order to the suspension system
System 100 coordinates, and longitudinal beam is also the wide rear end narrow structure in front end, convenient mutually assembling.More preferably, longitudinal beam corresponds to suspension
The position of second counter-jib 52 is widening structure in system 100, and its lateral surface and medial surface are variable section structure, with enhancing
The bulk strength of suspension 100.
The operation principle of the present embodiment trailer suspension 100 is identical with conventional suspension, and it possesses conventional suspension
While systemic-function and use, by the way that the second counter-jib 52 is designed into staggered floor construction, by the steel earlier above of rear spring 41
The unilateral inwardly biasing of flat spring 21 also be L1=90~175mm, the centre-to-centre spacing for reducing rear spring 41 be 180mm~
350mm, ensure the installation and use of low damage axletree；And each parts reasonable Arrangement of system can be made, ensure axletree, tire,
The activity space of the steering mechanism such as steering link and the normal use of transfer.It is meanwhile normal in trailer suspension 100
The stability in the case of use, reduce tire wear, improving steering behaviour and enhance trailer traveling.
Embodiment two
As shown in Figure 8 and Figure 9, the structure of the suspension 100 of the present embodiment trailer is roughly the same with embodiment one, different
Part is：The suspension 100 of the present embodiment trailer is five axis suspensions.
That is, in the present embodiment, light plate spring also includes the 3rd light plate spring 33.3rd light plate spring
33 are connected with the second light plate spring 32 and rear spring 41 respectively.Correspondingly, the 3rd light plate spring 33 and rear steel plate bullet
It is connected with each other between spring 41 by setting up the 4th counter-jib 54, the 4th counter-jib 54 passes through the 4th middle spring bracket 65 and trailer
Longeron is connected.3rd light plate spring 33 and the attachment structure of the second light plate spring 32 and rear spring 41 and front spring bullet
Spring 21 is identical with the connection of the first light plate spring 31, repeats no more.
The suspension 100 of the present embodiment, its second light plate spring 32, the 3rd light plate spring 33 and rear steel plate bullet
The unilateral centre-to-centre spacing for biasing L1=90mm~175mm to vehicle frame center line L0, reducing rear spring 41 of spring 41, to realize
The expansion of its outer space.
In other embodiments, the axis suspension of suspension 100 or three of trailer, or other Multi-shaft suspensions；Can also be
Other counter-jibs are designed to staggered floor construction, can realize that rear spring 41 to vehicle frame center-biased, is not made herein
Limit.
Suspension of the present utility model can be applied on all kinds of trailers, be effectively improved the use of trailer suspension
Performance, the application cost of low damage axletree is reduced, solve skill of the low damage axletree in multiaxis leaf spring balancing suspension system
Art bottleneck.Reduce tire wear, improve steering behaviour, the stability of increase trailer traveling.
Although describing the utility model with reference to above exemplary embodiment, it is to be understood that, term used is to say
Bright and exemplary and nonrestrictive term.Because the utility model can be embodied without departing from practicality in a variety of forms
