[technical field]
This utility model relates to the technical field that fork truck manufactures, particularly a kind of vehicle auxiliary wheel position limiting structure
Technical field.
[background technology]
The fork truck that warehousing forklift mainly designs for goods in stock carrying.Except minority warehousing forklift is to adopt
With manually driven, other are all with motor-driven, because its car body is compact, it is flexible, from heavy and light to move
It is widely used at warehousing industry with good environmental protection.Typically can be in the driving wheel left and right sides on warehousing forklift
Two set auxiliary wheel assemblies are installed and share the axle load of drive shaft side.Load first passes through support, then is transmitted by spring
On auxiliary wheel.Owing to when spring designs, fork truck typically can only be taken into account in the case of zero load and fully loaded two kinds
The magnitude of load scope of auxiliary wheel assembly, and fork truck can not be taken into account and held on centripetal side auxiliary wheel when turning to
The huge centripetal force being subject to.So when the spring on centripetal side auxiliary wheel assembly bears huge centripetal force when,
Spring is often compressed to the limit, makes spring material certain plastic deformation occur, it is impossible to return to design
Time state, have influence on the later normal use of fork truck.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of vehicle auxiliary wheel and limits
Bit architecture, it is possible to ensure that fork truck, when turning to, makes can to bear on centripetal side auxiliary wheel assembly bigger centripetal
Power, makes spring be not subject to huge centripetal force and produce plastic deformation, affects fork truck and normally use.
For achieving the above object, the utility model proposes a kind of vehicle auxiliary wheel position limiting structure, including interior
Hex screw, the first spring washer, the first plain washer, dust-proof door, the first circlip, bearing block,
Double-row angular contact bal bearing, the second circlip, seam support, Rectangular Spring, bolt, the second plain washer,
Second spring washer, hex nut, directly overlapping bearing, wheel carrier, described seam cradle top is arranged with successively
Two circlips, double-row angular contact bal bearing, bearing block, the first circlip, dust-proof door, first flat
Packing ring, the first spring washer, soket head cap screw, described seam frame bottom side is provided with spring mounting post,
Described Rectangular Spring is arranged in spring mounting post, and described wheel carrier is provided with installation post holes, and described wheel carrier leads to
Cross bolt and be arranged on seam frame bottom, described bolt is arranged with successively directly overlap bearing, the second plain washer,
Second spring washer, hex nut.
As preferably, described first circlip is circlip for shaft, and described second circlip is that hole is used
Circlip.
As preferably, described wheel carrier being provided with bolt collar, described bolt is arranged in bolt collar, institute
The quantity stating straight set bearing has two, and described straight set bearing is positioned at bolt collar.
As preferably, the quantity of described spring mounting post at least two, the position of described installation post holes and bullet
Spring mounting post one_to_one corresponding, the top, front side of described wheel carrier is provided with the first limited block, the rear side of described wheel carrier
Afterbody is provided with the second limited block.
The beneficial effects of the utility model: this utility model by by soket head cap screw, the first spring washer,
First plain washer, dust-proof door, the first circlip, bearing block, double-row angular contact bal bearing, the second bullet
Property back-up ring, seam support, Rectangular Spring, bolt, the second plain washer, the second spring washer, hex nut,
Directly overlap bearing, wheel carrier combines, through optimum experimental, when fork truck is turning to when, centripetal side
The huge centripetal force that auxiliary wheel assembly bears, is delivered on seam support, is then passed on Rectangular Spring,
Rectangular Spring is made to produce compression.Rectangular Spring is compressed to certain deformation when, first on wheel carrier
Produce rigid contact at front end on limited block and seam support, thus ensure that Rectangular Spring no longer continues pressure
Contracting, produces plastic deformation, thus ensures the normal use of vehicle.Simultaneously when fork-truck steering, non-centripetal side
Auxiliary wheel assembly, the least by the load born thereon, Rectangular Spring can be caused to be compressed
Part is released.Preventing Rectangular Spring during unclamping for wheel, Rectangular Spring spring from wheel carrier is pacified
Come off on dress post, when design, make seam support spacing by the second limited block at rear portion, thus ensure rectangle
Spring will not come off from auxiliary wheel assembly.This utility model ensure that fork truck, when turning to, makes centripetal side
Bigger centripetal force can be born on auxiliary wheel assembly, make spring be not subject to huge centripetal force and produce and mould
Property deformation, affect fork truck and normally use.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.
