Description
Technical field
The present invention relates to three-wheel vehicle, particularly a kind of three-wheel vehicle both legs front fork.
Background technology
At present, three-wheel vehicle especially electro-tricycle is the main transportation means of manpower, has that load carrying ability is big, the characteristics of maneuverability.Especially load-carrying three-wheel vehicle quality is bigger owing to three-wheel vehicle, and the car front fork that the fork leg that symmetry installs is constituted often is difficult to bear the impact in travelling, and causes the distortion of fork leg, damages, even have influence on person for driving a car's life security.Therefore, there is comparatively serious potential safety hazard in existing single leg front fork in the load-carrying requirement of aspect out of reach three-wheel vehicles such as intensity, damping.
By retrieval, do not find identical with present patent application or akin publication document as yet.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of intensity and toughness height, damping and safety performance good three-wheel vehicle both legs front fork.
The present invention solves its technical matters and is achieved through the following technical solutions:
A kind of three-wheel vehicle both legs front fork, comprise that fork standpipe, fork shoulder, fork leg and fork collude, the plane installs the fork standpipe on the fork shoulder, install two fork legs of symmetry at the lower plane of fork shoulder, all being fixed with a fork in the lower end of each fork leg colludes, it is characterized in that: installed a pair of fork leg again and made the fork leg form forward and backward two couple in the fork leg back that lower plane installed of fork shoulder, four uniform lower planes that are packed in the fork shoulder of fork leg, the fork standpipe is packed in the last planar central of fork shoulder.
And parallel the installing in the top of described fork shoulder pitched shoulder and made the fork shoulder form upper and lower two-layer on one.
And, described each fork leg by coaxial mounted outer fork leg and in the fork leg constitute, interior fork leg is coaxial to be installed in the outer fork leg, the outer fork leg lower end of homonymy installs a fork jointly and colludes.
And the described fork shoulder of going up installs in one pair of fork standpipe and the fwd and pitches leg, and the fork leg only is packed on the following fork shoulder in a couple of back.
And welding is fixed with the door frame plate between forward and backward two external fork legs.
And, be coaxially installed with the plastics sliding sleeve in the outer fork leg in each between fork leg and the outer fork leg.
And, pitch outside between leg and the interior fork leg damping spring is installed.
Advantage of the present invention and beneficial effect are:
1, these both legs front fork has installed another front fork again on original single leg front fork basis, forms the both legs front fork, can greatly strengthen the intensity and the rigidity of front fork thus, has improved the intensity of resisting of the central horizontal impact that produces that travels; Simultaneously, because the both legs front fork has increased a pair of damping spring again, also improved the damping performance of three-wheel vehicle, the corresponding comfort that increases the person for driving a car.
2, these both legs front fork fork that can make welding be packed in outer fork leg lower end colludes and has increased bonding area, has improved firm welding.
3, these both legs front fork integral structure is comparatively simple, though improved certain cost, has promoted safety, stability and the comfort level of three-wheel vehicle very effectively, and degree of innovation is higher, has promoted the development of load-carrying three-wheel vehicle industry effectively.

The specific embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
Embodiment 1: referring to Fig. 1,2,3.
A kind of three-wheel vehicle both legs front fork comprises that fork standpipe 1, fork shoulder 4, fork leg and fork collude 7, and the plane installs the fork standpipe on the fork shoulder, installs two fork legs of symmetry at the lower plane of fork shoulder, all is fixed with fork in the lower end of each fork leg and colludes.Innovative point of the present invention is: at the fork shoulder fork leg that lower plane installed is forward and backward two couple, four uniform fork shoulder lower planes that are packed in of fork leg, and the fork standpipe is packed in the center that the fork shoulder is gone up the plane.Concrete structure is:
1, the middle part on plane installs the fork standpipe on the fork shoulder, lower plane at the fork shoulder is that symmetry uniform installing in axle center pitched leg 3 in four with the fork standpipe, there is an outer fork leg 6 fork leg bottom with outer shaft sleeve in each, the lower end of the external fork of each of homonymy leg installs a fork jointly and colludes, the lower end of interior fork leg is the reducing mode, pitch the interior bottom of leg outside and install a transverse slat 11, in be coaxially installed with a bolt 9 with outer fork leg between reducing position, lower end and the outer fork transverse slat that leg installed of fork leg, pitch outside on interior interior fork leg of leg and the bolt between the transverse slat and be set with a damping spring 10.Present embodiment is to adopt damping modes, also can not adopt damping modes, and outer fork leg promptly is not set; Simultaneously, present embodiment adopts the interior leg plug-in mounting of pitching to go into outer mode of pitching in the leg, also can adopt and go into interior mode of pitching in the leg with pitching the leg plug-in mounting outward.
In order to improve the intensity of fork shoulder, and the stability that installs fork standpipe and interior fork leg, present embodiment parallel installing above the fork shoulder pitched shoulder 2 on one, promptly the fork shoulder forms shown in the drawings upper and lower two-layer as present embodiment, should go up the fork shoulder and install fork leg and fork standpipe in one pair of the fwd, the fork leg only is packed on the following fork shoulder in a couple of back; Certainly, also fork leg in a couple of back also can be packed on the fork shoulder.Present embodiment is provided with upper and lower individual layer fork shoulder mode, also can change a certain individual layer fork shoulder into double-deck fork shoulder, to improve fastness and stability under extraordinary circumstances require.
Externally pitch the fastness of leg and the stability that installs in order to improve two, externally weld between the fork legs in front and back two and be fixed with a door frame plate 5.
In addition, pitching outside in the leg for fork leg in improving can soft elastic telescopic, is coaxially installed with plastics sliding sleeve 8 in fork leg and the outer fork leg of pitching between the leg outward in each.
Embodiment 2: referring to Fig. 4.
And the difference of embodiment 1 only is damping spring is installed on interior fork leg and the outer interior fork leg of pitching between the leg, saves and pitches installation damping spring in the leg outside.
The mode of installing that the present invention is not described in detail is generally welding and installs, and also can adopt engagement to install.
