Description
Technical field
The utility model relates to Electrical Bicycle technical field, particularly relates to the car wheel structure of Electrical Bicycle.
Background technology
The wheel hub of Electrical Bicycle, comprise two side covers being installed on wheel shaft outer circumferential side, the periphery of two side covers is equipped with tire, by support installing controller, winding iron core between two side covers.In existing wheel hub, tire sleeve is placed in side cover periphery, easily skids, and service life is shorter, and not dismounting; Support installing is in the periphery of wheel shaft, and its setting accuracy is low; Support installing is in the axially middle part of wheel shaft, and the space between itself and side cover is less, and the installation of controller is inconvenient, and the lead-in wire of controller is unreasonable, is easily wound around.
Utility model content
The above-mentioned shortcoming that the applicant exists for the wheel hub of existing Electrical Bicycle, provide that a kind of inner space is large, easy disassembly, reasonable in design the wheel hub of Electrical Bicycle.
The technical scheme that the utility model adopts is as follows:
A kind of wheel hub of electric bicycle of built-in controller, comprise the support be installed between two side covers, between the periphery of two side covers, steel ring is installed, with the installing space of controller between support and side cover, with the installation annular space of winding iron ring between support and steel ring, described support entirety is in disk-like structure, comprise disk body and be positioned at the wheel shaft at disk body center, two side covers are rotationally connected by bearing and wheel shaft, and the axial side of wheel shaft, with thickening circle, describedly to thicken on circle with the mounting hole installed with wheel carrier; The junction of described disk body and wheel shaft is positioned at the position offset in the middle part of axle axial, with described installing space between disk body and a side cover, the periphery of disk body with bracing ring, with described installation annular space between described bracing ring and steel ring.
Further improvement as technique scheme:
Described side cover with protruding the flange of outer peripheral face, with mounting tyre and the screw hole fixing two side covers and steel ring on described flange.
The sidewall of described wheel shaft is with through wires hole.
The beneficial effects of the utility model are as follows:
Structure of the present utility model is simple, reasonable in design; Adopt off-centre support, for controller provides larger installing space, the installation of controller is simple, quick; Support is structure as a whole, and avoids the installation error of conventional two-piece; Adopt screw fastening structure installment tire, avoid tyre slip to wear and tear, increase the service life, reduce costs.
Accompanying drawing explanation
Fig. 1 is cutaway view of the present utility model.
Fig. 2 is the front view of the utility model medium-height trestle.
Fig. 3 is the A-A cutaway view in Fig. 2.
In figure: 1, side cover; 11, flange; 12, screw hole; 2, support; 21, disk body; 211, bracing ring; 22, wheel shaft; 221, circle is thickeied; 222, mounting hole; 223, through wires hole; 3, steel ring; 4, installing space; 5, annular space is installed; 6, bearing.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1 to Figure 3, the wheel hub of electric bicycle of the built-in controller of the present embodiment, comprise the support 2 be installed between two side covers 1, between the periphery of two side covers 1, steel ring 3 is installed, with the installing space 4 of controller between support 2 and side cover 1, with the installation annular space 5 of winding iron ring between support 2 and steel ring 3, support 2 entirety is in disk-like structure, comprise disk body 21 and be positioned at the wheel shaft 22 at disk body 21 center, two side covers 1 are rotationally connected by bearing 6 and wheel shaft 22, the axial side of wheel shaft 22 is with thickening circle 221, thicken on circle 221 with the mounting hole 222 installed with wheel carrier, disk body 21 and the junction of wheel shaft 22 be positioned at offset wheel shaft 22 axially in the middle part of position, with installing space 4 between disk body 21 and a side cover 1, the periphery of disk body 21 with bracing ring 211, with installing annular space 5 between bracing ring 211 and steel ring 3.
In the utility model, side side cover 1 and the wheel carrier of wheel hub are installed, and install without the need to both sides, it is easy for installation, simple to operate; In support 2, disk body 21 and wheel shaft 22 axially middle part maintain certain distance, thus the spacing increased between disk body 21 and side cover 1, namely installing space 4 is increased, be beneficial to the placement of controller, and due to the setting of large space, controller can make waterproof construction separately, be independently installed in installing space 4; Support 2 is structure as a whole, and avoids the installation error between disk body 21 and wheel shaft 22, and its precision is high, and improves installation effectiveness.
As shown in Figure 1, side cover 1 is with the flange 11 protruding outer peripheral face, and with mounting tyre and the screw hole 12 fixing two side covers 1 and steel ring 3 on flange 11, wheel is installed on side cover 1 by screw hole 12, ensures that tire is non-slip, and is easy to dismounting.Run through screw in screw hole 12, screw is placed in the outside of side cover 1, conserve space.
As shown in Figure 1, the sidewall of wheel shaft 22 is with through wires hole 223, and through wires hole 223 facilitates the installation of the electric wire of controller, avoids being wound around.
In the utility model, side cover 1 and support 2 all adopt aluminum alloy material, compare traditional steel structure wheel hub, not only ensure that intensity but also alleviate weight.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range is see claim, and when without prejudice to spirit of the present utility model, the utility model can do any type of amendment.
