Description

Car and wheel thereof that can stair climbing

Technical field

The utility model relates in general to car that can stair climbing; More particularly, relate to the wheel that this car uses.

Background technology

Wheel great majority that in the market can stair climbing are cardan wheel, and cardan wheel is exactly so-called movable castor, and its structure allows the horizontal 360-degree rotation.Castor is a general designation, comprises movable castor and rigid castors.Rigid castors does not have rotational structure, and can not horizontally rotate can only vertical rotation.These two kinds of castors are all generally collocation weeks, and such as the structure of hand barrow is two, front tight pulley, back is two movable cardan wheels near what promote handrail.Cardan wheel refers to that the support that is arranged on the castor wheel can horizontal 360-degree rotation in dynamic load or static load.Or three wheels that are mutually 120 degree rotate around center shaft.When these two kinds of wheels are gone upstairs and the friction force of stair corner angle larger, all relatively the effort.

The utility model content

One of the purpose of this utility model is to provide a kind of wheel that can stair climbing, and it is very laborsaving when stair climbing.

According to wheel that can stair climbing of the present utility model, comprise:

The main wheel of being made by aluminum alloy wherein is evenly distributed with between eight gear teeth and adjacent teeth and forms the right angle V-shaped groove on the excircle of main wheel;

The rubber roll of installing at the tooth top of each gear teeth of main wheel; And

Be fixed on the rubber friction sheet on the sidewall of each right angle V-shaped groove of main wheel.

Wheel of the present utility model can also comprise the rubber sleeve wheel on the excircle that is removably mounted on main wheel.

The circumcircle diameter of main wheel is preferably 20-25 centimetre, and the diameter of rubber roll is preferably 2 centimetres.

Rubber friction sheet can be fixed by screws on the sidewall of right angle V-shaped groove and the outer friction surface of rubber friction sheet can be provided with the zig-zag striped.

Another purpose of the present utility model is to provide a kind of car that can stair climbing, and it is more laborsaving and shockproof when stair climbing.

According to car that can stair climbing of the present utility model, comprise:

Axletree;

Be arranged on the above-mentioned wheel at axletree two ends;

Be arranged on the axletree two ends and be positioned at the inertia wheel of wheel inboard; And

Be arranged on the vehicle frame on axletree by spring damper.

The design of wheel of the present utility model and car, realized the function that can go the heavier goods of transportation to go upstairs by power still less.In addition, the rubber sheath wheel be complementary with wheel can make wheel slide on level land, makes the use of wheel more flexible, and it is upper to make clog-free perambulator or wheelchair to apply to perambulator, wheelchair etc.In addition, the use of spring damper has reduced the vibrations that bring in the car operational process, makes the car operation more steady.

The specific embodiment

Describe wheel of the present utility model and car in detail below in conjunction with accompanying drawing.It will be appreciated by those skilled in the art that the embodiment the following describes is only to exemplary illustration of the present utility model, but not for it being made to any restriction.

Referring to Fig. 1, wheel of the present utility model comprises main wheel 1, roller 2 and friction plate 3, and wherein main wheel 1 is made by aluminum alloy, and roller 2 and friction plate 3 are made by rubber.

As shown in the figure, the profile of main wheel 1 is similar to gear, and its circumcircle diameter is between 20-25 centimetre.Be evenly distributed with on the excircle of main wheel 1 between eight gear teeth and adjacent teeth and form the right angle V-shaped groove.These eight right angle V-shaped grooves can effectively agree with the corner angle of stair.

Roller 2 diameters can be 2 centimetres, are arranged on the tooth top of each gear teeth of main wheel 1.When the corner angle of stair can not be stuck in the V-shaped groove of main wheel, can by roller 2 regulating rotaries to, the stair corner angle are stuck in V-shaped groove.Except being conducive to the rolling of wheel on stair, roller 2 can also be as the small wheels roll-sliding on the half space of stair.

Friction plate 3 can adopt any suitable method for example closely to be fixed on the sidewall of each right angle V-shaped groove of main wheel 1 by screw.Friction plate 3 shown in Fig. 1-3 and Fig. 5 and Fig. 6 is arranged on a sidewall of right angle V-shaped groove, but also can on two sidewalls of right angle V-shaped groove, friction plate 3 all be set.As shown in Figure 4, the outer friction surface of friction plate 3 is provided with the zig-zag striped to increase the friction force of wheel and stair.Friction plate 3 can also protect roller 2 can not damage in operation.

Wheel of the present utility model can also comprise the outer wheel 8 on the excircle that is removably mounted on main wheel 1.Outer wheel 8 is also made by rubber, is the hollow circular ring type, and slightly larger in diameter is in the circumcircle diameter of main wheel 1.Outer wheel 8 adopts coarse screw to be connected with main wheel 1, facilitates installation and removal.When car during excessively to stair, can be unloaded rapidly outer wheel 8 down stair climbing from level land, when car from stair excessively to level land the time, can load onto rapidly outer wheel 8.

As shown in Figures 6 and 7, car of the present utility model comprises axletree 4, wheel or main wheel 1, inertia wheel 6, bumper 5 and vehicle frame 7.

Two wheels or main wheel 1 are arranged on axletree 4 two ends.Two inertia wheels 6 also are arranged on axletree 4 two ends, and adjacent wheel is arranged on inboard.Vehicle frame 7 can be made and is arranged on axletree 4 by spring damper 5 by reinforcing bar.Spring damper 5 can actv. reduce car in the process of stair climbing due to wheel and the vibrations that the stair corner angle rub and produce, make the more steady of trolley travelling.Two 6 of inertia wheels can make car all more laborsaving on level land or in the process of stair climbing.

With traditional pass through three wheels sway realize that the wheel of stair climbing function compares with dolly, wheel provided by the utility model and car have overcome the shortcoming that conventional wheel and dolly are required great effort upstairs.Simultaneously, the utility model, by the design of wheel and car, has been realized the function that can go the heavier goods of transportation to go upstairs by power still less.The rubber sheath wheel be complementary with wheel can make wheel slide on level land, makes the use of wheel more flexible, and can apply on perambulator, wheelchair etc. and make clog-free perambulator or wheelchair.
