Abstract
The utility model is a kind of comprehensive low resistance platform running gear, this device relies on air cushion load capacity, load-carrying capacity is strong, required propulsive effort is little, and surface damage is little over the ground, adds four groups of omni-directional wheels, platform is not when changing self pose, just can realize omnibearing movable, motion flexibly, overcomes the defect that common shipping platform cannot carry out all-around mobile neatly in small space.
Description
Technical field
The utility model is a kind of comprehensive low resistance platform running gear, belongs to the technical field of structures of product.
Background technology
The motion of current carrying platform has various mode, and most of indoor transporting platform bearer ability is little, and required propulsive effort is large, move dumb, surface damage is large etc. over the ground, particularly at some special occasions, as realized the all-around mobile in small space.
Summary of the invention
The utility model designs for the shortcoming existed in above-mentioned prior art just and provides a kind of comprehensive low resistance platform running gear, this device relies on air cushion load capacity, load-carrying capacity is strong, required propulsive effort is little, and surface damage is little over the ground, adds four groups of omni-directional wheels, platform is not when changing self pose, just can realize omnibearing movable, motion flexibly, overcomes the defect that common shipping platform cannot carry out all-around mobile neatly in small space.
The purpose of this utility model is achieved through the following technical solutions:
This kind of comprehensive low resistance platform running gear, comprise a platform (5) and be arranged on four groups of omni-directional wheels (2) bottom platform (5), the installation site of four groups of omni-directional wheels (2) is in symmetrical between two, the hub axis of four groups of omni-directional wheels (2) is equal with the distance between ground, it is characterized in that: install two groups or more air-cushion unit for carrying platform weight (1) in the bottom of platform (5); On the wheel hub of omni-directional wheel (2), install the roller with hub axis angle at 45 ° along arrangement between outer, wheel hub both sides, each roller all can rotate along its own rotation axis, and roller is concentric circles along the enveloping outer enclosure of wheel hub and wheel hub.When omni-directional wheel (2) and earth surface, at least will there be a roller and earth surface each omni-directional wheel (2) any time, and four groups of omni-directional wheels (2) are rectangle or square profile.
The advantage of the utility model device is:
1. this device adopts the weight of air cushion carrying platform, improve load-carrying capacity, by the control to air cushion air pressure, after air cushion inflation, make itself and ground form one deck air film, greatly reduce the friction force between motion platform and ground, decrease the propulsive effort of motion platform simultaneously.
2. the traveling gear of this device adopts 4 omni-directional wheels that can independently control to drive, by turn to four omni-directional wheels and the control of speed can realize this stage apparatus and moves along any direction.

Fig. 2 is layout and the structural representation of omni-directional wheel and roller
Fig. 3 is the integral structure schematic diagram of the utility model device
Detailed description of the invention
Below with reference to drawings and Examples, the utility model is further described:
Shown in accompanying drawing 1 ~ 3, this kind of comprehensive low resistance platform running gear, four groups of omni-directional wheels 2 that this device comprises a platform 5 and is arranged on bottom platform 5, the installation site of four groups of omni-directional wheels 2 is symmetrical between two by oblong or square, the hub axis of four groups of omni-directional wheels 2 is equal with the distance between ground, it is characterized in that:
On the wheel hub of omni-directional wheel 2, install the roller with hub axis angle at 45 ° along arrangement between outer, wheel hub both sides, each roller all can rotate along its own rotation axis, and roller is concentric circles along the enveloping outer enclosure of wheel hub and wheel hub.By to the hand of rotation of each omni-directional wheel and the control of rotative speed, just can realize the omnidirectional moving of whole motion platform, comprise advance, retrogressing, translation, oblique movement, turning and rotation etc.As 4 wheels rotate forward with identical speed time, platform 5 can march forward along X; If wheels I 21, wheels IV 24 rotate forward, wheels II 22, wheels III 23 take turns reversion, and platform 5 can move to right along Y-direction; If wheels I 21, wheels III 23 take turns rotating forward, wheels II 22, wheels IV 24 reverse, can the right-hand rotation of implementation platform 5; By to each hand of rotation of omni-directional wheel 2 and the control of rotative speed, also can implementation platform turn, the motion such as oblique, original place rotation.
Arrange between omni-directional wheel 2 and the support 3 of platform 5 and take turns suspension 4, adopt the elastic mechanisms such as the air-cushion unit 1 of parallelogram sturcutre and controlled air bag of exerting pressure or spring that omni-directional wheel 2 is contacted constantly with ground.Omni-directional wheel 2 is controlled with platform 5 bottom hung, during to ensure that air-cushion unit 1 is not inflated, main hard point is on air cushion, instead of on omni-directional wheel 2, when ensureing that air cushion inflation floats formation air film 8 simultaneously, omni-directional wheel 2 and ground have certain positive pressure, to move required propulsive effort to meet platform 5.
The main hard point in the bottom of platform 5 is installed four groups of air-cushion units 1, its installation site is in symmetrical between two, its principle is that the mass loading 6 of motion platform 5 is carried by air-cushion unit 1, when air-cushion unit 1 fills after pressurized air 7 holds up platform 5, it and ground form the high stability air film 8 of one deck, effectively reduce the friction force between motion platform 5 and ground like this, and the platform 5 required propulsive effort that moves is reduced, reduce the damage to ground simultaneously, platform 5 is moved more flexible.
Compared with prior art less, the omnibearing ambulation that can realize neatly in small space of strong, the required propulsive effort of this stage apparatus load-carrying capacity.
Claims (2)
1. a comprehensive low resistance platform running gear, this device comprises a platform (5) and is arranged on four groups of omni-directional wheels (2) of platform (5) bottom, the installation site of four groups of omni-directional wheels (2) is in symmetrical between two, the hub axis of four groups of omni-directional wheels (2) is equal with the distance between ground, it is characterized in that: install two groups or more air-cushion unit for carrying platform weight (1) in the bottom of platform (5); On the wheel hub of omni-directional wheel (2), install the roller with hub axis angle at 45 ° along arrangement between outer, wheel hub both sides, each roller all can rotate along its own rotation axis, and roller is concentric circles along the enveloping outer enclosure of wheel hub and wheel hub.
