Abstract
The utility model relates to an improved integrated type wheel hub for an electric tricycle comprising a wheel rim, a central seat and a plurality of ribs uniformly distributed between the wheel rim and the central seat. The utility model is characterized in that a plurality of auxiliary reinforcements are arranged on both sides of each rib and mutually connected with each other; each rib is integrally arc shaped and is provided with two parallel grooves; the intersection part between each rib and the reinforcement is arc shaped and a concave part extends in circumferential direction on the central seat; the wheel rim, the central seat, the ribs and the auxiliary reinforcements are cast into one body. For the device adopting the technical proposal that the integrated wheel hub is cast by gravity; the wheel rim, the central seat, the ribs and the reinforcements are connected without solder joints; every rib is integrally arc shaped, thus the wheel hub has improved mechanical property and greatly improved tensile strength; thereby the problems of fracture, deformation, load limitation and no uniform deadweight of the wheel hub are solved.
Description
Affiliated field
The utility model belongs to the accessory of vehicle, specifically belongs to the wheel hub of electro-tricycle.
Background technology
Little, the emission-free discharging of electro-tricycle noise, free from environmental pollution, it is a kind of transportation work of environment-friendly type, application in cities and towns is more and more universal, the wheel hub of electro-tricycle is one of major part of electro-tricycle, existing electric three-wheel wheel hub mostly adopts steel ring and spoke structure, its production process complexity of the wheel hub of this structure, strength coefficient, steel ring and spoke be easy to generate get rusty, the many problems of work such as distortion, breakage, incompatible existing carrying is heavy, the demand of the battery-driven car three-wheel vehicle of fireballing characteristics.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of intensity height, monolithic devices electric three-wheel wheel hub that bearing capacity is big are provided.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of improved monolithic devices electric three-wheel wheel hub, comprise wheel rim and centre mount, be evenly distributed with some muscle between wheel rim and centre mount, it is characterized in that: the both sides of every muscle are provided with interconnective auxiliary reinforced rib, every muscle integral body is curved, every muscle is provided with two parallel grooves, every muscle and auxiliary reinforced rib intersection are a camber line, centre mount is provided with the recess that circumferentially extends along it, and wheel rim, centre mount, muscle, auxiliary reinforced rib are cast as an integral body.
By above technical scheme as can be known: because whole wheel hub is the gravity casting casting, the junction does not have solder joint between wheel rim, centre mount, muscle, the auxiliary reinforced rib, every muscle integral body is curved, mechanical property, the tensile strength of wheel hub are increased substantially, solved in the past problem such as rupture, distortion, load-carrying limitation, wheel hub deadweight are inhomogeneous, every muscle is provided with two parallel grooves, further alleviate the weight of wheel hub on the one hand, make the moulded elegant in appearance, fashionable of wheel hub on the other hand, especially be fit to the electro-tricycle of tire more than 18 cun.
Description of drawings
Fig. 1 is a Facad structure scheme drawing of the present utility model.
Fig. 2 is a structure scheme drawing of the present utility model.
The specific embodiment
Referring to Fig. 1, a kind of monolithic devices electric three-wheel wheel hub, it comprises wheel rim 1 and centre mount 2, and wheel rim 1 is provided with valve port 3, is provided with in the centre mount 2 to be used to install the mounting hole 4 of axis and to play the keyway 5 that fixedly is used as, establish the recess 6 that circumferentially extends along it on the centre mount 2,2 of wheel rim 1 and centre mounts are distributed with some muscle 7, and muscle 7 best rectangular distributions are to keep whole wheel hub deadweight evenly, the quantity of muscle 7 can be set according to actual conditions, preferred 5.
Referring to Fig. 2, the both sides of every muscle 7, promptly the back side is provided with auxiliary reinforced rib 8, auxiliary reinforced rib 8 is positive mutually to be connected, every muscle 7 is whole curved, and every muscle 7 is a camber line 9 with auxiliary reinforced rib 8 intersections, and wheel rim 1, centre mount 2, muscle 7, auxiliary reinforced rib 8 are cast as an integral body.
In order further to alleviate the weight of wheel hub, every muscle 7 is provided with two parallel grooves 10, and the effect of groove 10 is set, and further alleviates the weight of wheel hub on the one hand, make the moulded elegant in appearance, fashionable of wheel hub on the other hand, especially be fit to the electro-tricycle of tire more than 18 cun.
