Abstract
The invention relates to the structure and shape of a universal wheel, disclosing a new universal wheel, composed of big and small waist drum rollers, batwing bracket, long and short mandrels, side cover plate, bearing, sleeve, central shaft, wheel frame and so on. Its character: the two rollers and the two mandrels fixed on the batwing bracket compose the wheel edge, the batwing bracket is linked with the side cover plate, and the bearing, the central shaft and the wheel frame are installed in the center of the side cover plate, thus composing it. It uses the two rollers to compose double-freedom mechanism, thus able to be pushed in an arbitrary direction to move without rotating the direction of the wheel when used, saving the rotary space. In addition, it has not only better stopping property to prevent the sand from intruding into the inner cavity of the rollers, but also has advantages of reasonable structure, good technique, etc.
Description
Technical field
The present invention relates to the structure and the shape of cardan wheel, is the structure and the shape of the later-model cardan wheel that just can be on the level land moves towards any direction with the external force effect of a kind of not rotating wheel direction specifically.
Background technology
Traditional universal caster wheel is subjected to the promotion of external force, its wheel must redirect to and could drag it by external force when consistent with external force direction and move along external force direction, when external force changes sense of motion, traditional universal caster wheel needs one section process of adjusting wheel direction, phenomenon so in use often appears waving, use dumb, and traditional universal caster wheel is subjected to the direction and wheel off centering one segment distance of load, make wheel carrier produce very large eccentricity moment, influence the service life of wheel carrier, also have traditional universal caster wheel installing space to give and reserve wheel around the rotating space of wheel carrier vertical shaft.
The inventor has proposed utility model in December, 2002, patent of invention and PCT application, application number: 02291781.0, and 02130670.2 " a kind of later-model cardan wheel " of three same structures of PCT/CN02/00880, its embodiment is that Y type support is installed on little drum-shaped roller, but this Y type support exists weak point, this support will pass and be fixed on half wheel hub groove center between two big drum-shaped rollers, such structure can influence wheel can not install other parts in the centre, as antifriction-bearing box etc., space, end at big or small drum-shaped roller connection big waist drum type roller is bigger, invaded by sand easily, influence the rotation of big small roller, half wheel hub structure of both sides and manufacturability complexity, the corresponding tooling cost that improved.
Show that according to related datas such as Chinese patent retrievals present except that I invent do not have single roller to need not the report that the rotating wheel direction can be pushed the later-model cardan wheel that any direction moves with the external force effect in use as yet.
Summary of the invention
In order to overcome the defective of structure, performance, installation and the use etc. that have cardan wheel now, the invention provides a kind of later-model cardan wheel.
The technical solution adopted for the present invention to solve the technical problems is: a kind of later-model cardan wheel that is made of parts such as big or small drum-shaped roller, bat shape support, length axle, side cover plate, bearing, sleeve pipe, center shaft and wheel carriers is characterized in that: the wheel rim that the outer ring of wheel is made up of big or small waist drum type roller; Central mounting at little waist drum type roller has a long axle, the long axle of little waist drum type roller centre is mounted on the bat shape support, also respectively have an axis hole that the short axle of big waist drum type roller can be installed below about bat shape support, so little waist drum type roller just can freely rotate on bat shape support; And big waist drum type roller is enclosed within on the short axle, can inject bat shape lower left, support two ends or lower right because the both ends of big waist drum type roller are fluted, between two bat shape supports big waist drum type roller bearing is got up, so big waist drum type roller also can freely rotate; The size drum-shaped roller has constituted wheel rim by bat shape bracket supports; At the side cover plate central mounting bearing is arranged, bearing center is a center shaft, and wheel carrier is installed on the center shaft, and they have constituted cardan wheel of the present invention.Described long axle left part is that the half moon spindle nose matches with bearing oblique crank Z in the first half of the month hole on the bat shape support left side, has axis hole to be connected with long axle spindle nose on the right bearing of bat shape support, and rivets together.Described short axle two ends spindle nose is all made the half moon spindle nose and is connected with the oblique below of bat shape support half moon axis hole.Described bat shape mid-stent is flat trapezoid boss on the two sides, also there is being its position of flat trapezoidal slotted eye corresponding on two side cover plates with flat trapezoid boss on the bat shape support, so big or small drum-shaped roller, bat shape support, along the circumferential direction single uniform the assembling up of length axle, aim at flat trapezoid boss insertion on the bat shape support by two side cover plates, so just big or small drum-shaped roller and bat shape support are fixed between two side cover plates.Described big or small drum-shaped roller quantity is 3 pairs～30 pairs.Can be installed on the carrier with three or four cardan wheels of the present invention during use, just can make carrier on the level land, arbitrarily push the place of any direction to.
The invention has the beneficial effects as follows: cardan wheel of the present invention utilizes big or small drum-shaped roller to form double freedom mechanism because used big or small drum-shaped roller on the wheel rim, can arbitrarily push any direction to and moves thereby need not the rotating wheel direction when using.Cardan wheel of the present invention does not need the rotating wheel direction, thus save the structure rotation space, and also cardan wheel of the present invention is stressed good, does not have eccentric moment, long service life.Cardan wheel of the present invention is owing to overcome my former invention 02130670.2,02291781.0 and the defective of PCT/CN02/00880 and the problem of existence, so make more reasonable structure, compacter, so big or small drum-shaped roller is connected good, the gap is very little, 1 millimeter is only arranged, so operate steadily noiseless.In addition, cardan wheel leak tightness of the present invention is better, avoids sand to invade the roller inner chamber.Therefore, cardan wheel of the present invention has rational in infrastructure, and good manufacturability is easy for installation, low cost and other advantages.
