Description
Technical field
The utility model relates to the technical field of fork truck accessory, especially relates to a kind of twins drive axle of side V shape fork truck.
Background technology
The particularity of the design of side forklift in the market on drive wheel, be that pressure and the rear overhang moment of torsion that drive wheel will carry substantially exceeds pressure and the front overhang moment of torsion that wheel flutter carries, so strengthening its ability to bear in drive axle part is necessary, drive axle is made up of main reduction gear, diff, semiaxis and axle housing, driving axle of forklift is the important component part of fork truck drive system, its effect is that the power that universal driving device is transmitted was rolled over 90 ° of angles, changes the direction of transfer of power.The end of drive axle in Power Train, its basic function is that the motor torque that universal driving device is transmitted passes to driving wheel by main reduction gear, diff, semiaxis etc., realizes reduction of speed and increases torque; Change the direction of transfer of torque by main reduction gear taper gear pair; Realize both sides wheel differential action by diff, ensure that medial and lateral wheel turns to different rotating speeds; Realize carrying and intermal force by axle housing body and wheel.Although current side forklift can be accomplished basic load-carrying capacity, but when through potted road surface, the phenomenon of easily blowing out, and also in braking, stopping distance is larger, in the time that fork truck load-carrying is more, the distance of braking can affect staff's life security.
Summary of the invention
The deficiency existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of overall performance that increases fork truck, make propulsive effort, drag friction power, vehicle stability, tire used safety all well be promoted and ensure, and staff's life security also be provided to the twins drive axle of the side V shape fork truck of corresponding guarantee.
For realizing above-mentioned object, the utility model provides following technical scheme:
A kind of twins drive axle of side V shape fork truck, comprise the body of drive axle, on the axle at the two ends of described body, be arranged with respectively two wheel hubs, the opening of two wheel hubs on the axle of every end all in the opposite direction, and the bottom surface of two wheel hubs on the axle of every end contacts, on the axle at described two ends, be respectively equipped with annular boss, on boss, be respectively equipped with several mounting holes, on the bottom surface of described two wheel hubs, be respectively equipped with the through hole matching with mounting hole, two wheel hubs of described every end pass mounting hole by bolt of rear end plate respectively and through hole is fixed on boss.
The utility model is further set to: described wheel hub comprises wheel rim, back-up ring and spoke, the rear end of described wheel rim is fixedly connected with spoke, described back-up ring fixed cover is located at the afterbody of wheel rim, is evenly equipped with the bolt hole that several and described through hole and mounting hole match on the end face of described spoke.
The utility model is further set to: after the outside bending of limit portion of the front end of described wheel rim, bend forward forms flange one again.
The utility model is further set to: after the rear end necking down of described wheel rim its limit portion more outwards bending form the draw-in groove with rib.
The utility model is further set to: described shield ring sleeve is located in described draw-in groove.
The utility model is further set to: the limit portion of described back-up ring is bent to form flange two backward.
The utility model is further set to: described bolt hole is the hole that middle part tilts from inside to outside to the bore edges of its both sides.
By adopting technique scheme, the technique effect that the utility model reaches is: the overall performance that increases fork truck, make propulsive effort, drag friction power, vehicle stability, tire used safety all well be promoted and ensure, when through potted road surface, the propulsive effort that twins drive wheel is given is very outstanding, and the more difficult phenomenon of blowing out, because of the increase of tyre surface, while making to brake, can reduce stopping distance, also provide corresponding guarantee to staff's life security.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is integral structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of wheel hub of the present utility model.
Detailed description of the invention
As Fig. 1, shown in Fig. 2, for the twins drive axle of the disclosed a kind of side V shape fork truck of the utility model, comprise the body 10 of drive axle, on the axle at the two ends of described body 10, be arranged with respectively two wheel hubs 11, the opening of two wheel hubs 11 on the axle of every end all in the opposite direction, and the bottom surface of two wheel hubs 11 on the axle of every end contacts, on the axle at described two ends, be respectively equipped with annular boss 12, on boss 12, be respectively equipped with several mounting holes 13, on the bottom surface of described two wheel hubs 11, be respectively equipped with the bolt hole 14 matching with mounting hole 13, two wheel hubs 11 of described every end are fixed on boss 12 through mounting hole 13 and bolt hole 14 by bolt of rear end plate 15 respectively.
In above-mentioned, described wheel hub 11 comprises wheel rim 16, back-up ring 17 and spoke 18, the rear end of described wheel rim 16 is fixedly connected with spoke 18, described back-up ring 17 fixed covers are located at the afterbody of wheel rim 16, on the end face of described spoke 18, be evenly equipped with the bolt hole 14 that several and described mounting hole 13 match, the hole that described bolt hole 14 tilts to the bore edges of its both sides from inside to outside for middle part.After the outside bending of limit portion of the front end of described wheel rim 16, bend forward forms flange 1 again, after the rear end necking down of described wheel rim 16 its limit portion more outwards bending form the draw-in groove 22 with rib 21, described back-up ring 17 is sheathed in described draw-in groove 22, and the limit portion of described back-up ring 17 is bent to form flange 2 19 backward.
