Description
Technical field
The present invention relates to cart technical field, be specifically related to a kind of compact being applied to cart
Post-suspension structure and cart thereof.
Background technology
The rear suspension system of sulky vehicle (such as motorcycle, electric motor car etc.) mainly has a following several ways:
1, damping type after left and right is double, rear suspension of motorcycle as a kind of in Chinese invention patent (CN105329396A)
Device includes vehicle frame, back vent, rear shock absorber, connecting rod and connecting plate；Connecting plate is for having three hinge holes
Platy structure；Connecting plate is hinged with hind axle by the hinge hole I being positioned on hind axle axle center；Connecting plate
It is articulated and connected by one end of hinge hole II with connecting rod；The other end of connecting rod is hinged on vehicle frame；Rear shock absorber
Upper end be articulated and connected with vehicle frame；The lower end of rear shock absorber is hinged with the hinge hole III of connecting plate, hinge hole III
The bottom of hinge hole I it is positioned at initial position.There is cost height in this kind of rear-mounted, both sides damping needs to control
The problems such as concordance.
2, damping type after central authorities are single, as it is shown in figure 1, the two ends of amortisseur 201 are respectively articulated with vehicle frame 202 He
The cross bar 205 in trailing wheel 204 front it is positioned on chain stay 203.Chain stay front portion is occupied at this kind of rear suspension system
Larger space, causes the increase of chain stay length, stress to become big, the problems such as vehicle wheelbase is long.
3, damping type after reel cage formula central authorities are single, as Chinese utility model patent (CN201432776) discloses
A kind of back hanging device for motorcycle, including vehicle frame, rear shock absorber and chain stay, rear shock absorber lower end is hinged with three
The connecting plate of dihedral, the journal stirrup arranged on the downside of a hinge of connecting plate and chain stay is hinged, another hinge of connecting plate
Point is hinged with one end of rear shock absorber, and the 3rd hinge of connecting plate is hinged with one end of rocking arm, described rocking arm
After the other end and vehicle frame, the journal stirrup of pipe is hinged；The chain stay articulated section that described chain stay is provided with axis hole by front end is hinged
After vehicle frame on pipe, after chain stay and vehicle frame, the chain stay articulated section of pipe is provided with the fuel filler neck for oil addition.
Although this kind of rear-mounted improves damping effect, but occupies the space that chain stay is anterior equally, cause chain stay long
Degree increases, stress becomes big, the problems such as vehicle wheelbase is long.
Additionally, in above-mentioned three kinds of rear suspension systems, bottom fork axis is monoblock type, by lining or needle roller
Chain stay fixed by bearing, thus installation place axially compressed behavior is poor.
Summary of the invention
For the above-mentioned problems in the prior art, after now providing a kind of compact being applied to cart
