Abstract
The utility model relates to a kind of compound scroll wheels, belong to General Mechanical Parts field.Obstacle detouring cannot be rolled when to overcome existing universal wheel to encounter the barriers such as handstone, small stair, and common major diameter scroll wheel is easy to cross these small barriers, but problem can only be rolled along fixed-direction, the utility model discloses a kind of compound scroll wheels.Universal wheel and common scroll wheel groups are combined, realization can either flexibly turn to and being capable of obstacle detouring.Realizing the technical solution of above-mentioned utility model is: universal wheel being evenly arranged on wheel disc, bind mode is threadedly coupled.Compound scroll wheel disclosed by the utility model can take into account flexibly commutation and two functions of obstacle detouring.
Description
Technical field
The utility model relates to a kind of scroll wheels, belong to machine component field, relate in particular to a kind of compound scroll wheel.
Background technique
General universal wheel has direction flexibility, but when it encounters the barriers such as handstone, small stair cannot roll
Obstacle detouring.The wheel of common major diameter is easy to cross these small barriers, but can only roll along fixed-direction, cannot arbitrarily change
Variable roll direction.Publication No.: the utility model patent of CN2499251Y discloses a kind of (universal) efficiency passing wheel, but its ten thousand
Jib-length to fork is long, and the internal stress of generation is big, and ball frictional force is big, rotates inflexible.
Small-sized vehicle frame, the luggage truck that can either conveniently cross small obstacle in order to realize, and can flexibly move etc.
Movement, the utility model disclose a kind of compound scroll wheel for combining universal wheel and common wheel, gather the excellent of the two
Point, realization can either flexibly turn to and being capable of obstacle detouring and reduction omnidirectional mechanism jib-lengths.
Summary of the invention
Realizing the technical solution of above-mentioned utility model is: universal wheel being evenly distributed on the circumference for being attached to scroll wheel, is existed in this way
When normal flat overground locomotion, carried out rolling Forward and steering by universal wheel, when encountering obstacle, then wheel disc rolls obstacle detouring.This is practical
Novel particular content is:
A kind of compound scroll wheel, by one group of 2, one, wheel disc, 4, one, bearing fixing piece of pivot pin 3, one of universal wheel 1, one
5 are constituted, it is characterized in that: the universal wheel 1 is evenly arranged on the circumference of wheel disc 2；
The universal wheel 1 is at least three or more and is evenly distributed with；
The ratio between maximum outside diameter is not more than 1:2 when 2 diameter of wheel disc and universal wheel 1 are installed to wheel disc 2；Universal wheel 1 it is straight
The circumcircle diameter ratio of diameter and wheel disc 2 is 1:3 or more；
Bind mode of the universal wheel 1 on wheel disc 2 has welding, bonding, threaded connection and screw to be coupled；
There are two types of structures for wheel disc 2, one is circular configuration；The second is just more square structures.
Compound scroll wheel disclosed by the utility model has the advantage that
(1) it can flexibly commutate；
(2) it can be convenient obstacle detouring；
(3) most dangerouse cross-section internal stress is small small with the frictional force of ball.
Detailed description of the invention
Fig. 1 is the main view of compound scroll wheel；
Fig. 2 is the left view of compound scroll wheel；
Fig. 3 is the schematic shapes of wheel disc 2；
The meaning that expression is respectively marked in figure is as follows:
1-universal wheel, 2-wheel discs, 3-pivot pins, 4-bearings, 5-fixing pieces.
Specific embodiment
1 provide specific embodiment with reference to the accompanying drawing.
One embodiment of the utility model is that six small universal wheel 1 is evenly arranged on wheel disc 2, and bind mode is connected with screw thread
It connects on round wheel disc 2.
Another embodiment of the utility model is that eight small universal wheel 1 is evenly arranged on the wheel disc 2 of all directions shape, wheel disc 2
Using etc. eight square structures, universal wheel 1 is on four screws connection wheel discs 2.
These principles are identical, and variation can constitute the other embodiments of the utility model on specific structure.
