Description
Technical field
The utility model discloses a kind of novel omnidirectional wheel, belong to a kind of omnidirectional wheel.
Background technology
Omnidirectional's wheel is a kind of wheel that can be used to build comprehensive mobile platform.Its feature is to be distributed with the steamboat angled with bull wheel around larger wheels.Bull wheel can be used as driving wheel or flower wheel, and steamboat is as flower wheel.If bull wheel rotates as driving wheel, omnidirectional's wheel just only can offer frame along the power of steamboat on axially, is free to slide on little wheel radial.
The bull wheel of existing omnidirectional wheel and the angle of steamboat are divided into 90 degree and 45 usually and spend two kinds.When the omnidirectional more than three or three wheel is mutually certain angle when arranging, by the velocity composition between the control wheel, the equipment of can realizing under situation about not turning to directly to the motion of any direction.Because this feature, the mobile platform of utilization omnidirectional wheel is compared common train platform, has higher kinematic dexterity, can adapt to and more move in the narrow space.
Existing 90 degree omnidirectionals wheels can be divided into single and two kinds of double-banks usually.Single wheel is owing to exist the gap between each steamboat, and whole wheel outer is discontinuous, and rotation has shake, and robust motion and continuity are relatively poor.Existing double omnidirectional wheel, ubiquity complex structure, shortcoming such as manufacturability is poor, is unfavorable for industrialized mass production, and load-carrying capacity is lower.
Having occurred the patent No. subsequently is 200920212646.0, and the applying date is the patented technology scheme of 2009-12-07, and the technical scheme of this patented technology is as follows:
A kind of new omnidirectional wheel, it is characterized in that, comprise: forward and backward single-wheel dish, form by wheel hub and flower wheel, at least three Y shapes of rectangular distribution branch on the circumference of described wheel hub is respectively offered a concentric circular hole between the adjacent in twos described Y shape branch, and a little wheel shaft is located between described two circular holes, described flower wheel is located on the described little wheel shaft, and the radius of described forward and backward single-wheel dish equals the axial cross section profile arc radius of described flower wheel; The wheel core print seat comprises a centre hole; Wherein, some fasteners are fixed on described the wheel on the core print seat with the described forward and backward wheel disc 30 ° of angles of staggering mutually.The shortcoming of this technical scheme is:
1, complex structure, manufacturing procedure is many, is difficult to realize industrialized mass production.
2, concentric circle holes processing difficulties in twos on the wheel hub.
3, little wheel shaft is deviate from the axial direction easily.
4, stock utilization is low, under the equivalent material intensity a little less than.
The utility model content
The utility model provides a kind of later-model omnidirectional wheel, and whole double omnidirectional wheel wheel hub can only be processed by a bulk metal plate.And the structure of this omnidirectional wheel is simple relatively, good manufacturability, and the bulk strength height is convenient to industrialized mass production.
For realizing above-mentioned technical purpose, the technical solution of the utility model is as follows:
A kind of novel omnidirectional wheel, comprise wheel hub and flower wheel, described wheel hub is by at least one metal sheet punch forming, the annular working face of wheel hub is provided with the groove of a plurality of being shaped as " protruding " shape, " protruding " shape end face of groove is along the axial setting of wheel hub, a plurality of grooves connect as one, and " protruding " shape end face of adjacent two grooves is opposing, and flower wheel is arranged in the groove through adapter shaft and perpendicular to the axial direction of wheel hub.
" protruding " shape end face of described groove has connecting bore, connecting bore be respectively equipped with along wheel hub annular working face both sides perpendicular to hub spindle to and with first arc of adapter shaft coupling.
Also comprise cover plate and attaching parts, cover plate is provided with the hole, and the both sides, hole are provided with second arc with the adapter shaft coupling, and first arc is relative with the concave surface of second arc, and " protruding " shape end face of cover plate and wheel hub upper groove coincide, by the attaching parts captive joint.
Described first arc or second arc are punch forming.
Described wheel hub upper edge diametric(al) also is provided with ripple.
The beneficial effects of the utility model are as follows:
1, because the utility model has adopted metal sheet is struck out the groove of arranging to dislocation along hub spindle, flower wheel is arranged in the groove of both sides, therefore, realized directly making double omnidirectional wheel wheel hub by the single piece of metal plate, simple in structure, good manufacturability is convenient to industrialized mass production.Omnidirectional's wheel double-bank structure is compared single, and driving surface is more approaching just round, and is more steady during running.
2, because the utility model adopts the axle of the convex surface clamping flower wheel of a cover plate and wheel hub upper groove, the deep-slotted chip breaker of convex surface is relative on deep-slotted chip breaker on the cover plate and the wheel hub, fix by attaching parts, therefore, under better simply mode, realized more firm the fixing of little wheel shaft.
3, because wheel hub of the present utility model and cover plate all adopt punch forming, therefore, the manufacture craft of omnidirectional's wheel is simple.
4,, therefore, under the prerequisite that does not increase material, increased the intensity of omnidirectional's wheel because wheel hub upper edge diametric(al) is provided with ripple.
