Description
Technical field
A kind of liftable caravan trailer is the utility model is related to, specifically one kind pulls caravan chassis wheel liter
Descending mechanism and lift pull caravan chassis.
Background technology
Caravan chassis should have good stability, ensure caravan security and comfortableness.Prior art is used in room
The structure of several supporting legs that can be stretched is installed on the polycrystalline substance of car, when needing to fix caravan, stretches out supporting leg,
Against on the ground, the stability of caravan is improved to a certain extent.But because supporting leg is usually slim-lined construction, in strong wind etc.
Under mal-condition, caravan still has the risk toppled over., can be by the chassis design of caravan in order to further improve the stability of caravan
Into liftable structure, the center of gravity of caravan is reduced, can also improve the stability of caravan.But prior art can only finite reduction caravan
Chassis height, chassis can not still be implemented on the ground completely.
Utility model content
The utility model provides that one kind pulls caravan chassis vehicle wheel lifting mechanism and lift pulls caravan chassis, solves
Caravan chassis can directly implement technical problem on the ground, improve the stability and security on caravan chassis.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that：
One kind pulls caravan chassis vehicle wheel lifting mechanism, including the wheel group for support chassis, it is characterised in that described
Wheel group includes rotating shaft, two connecting levers and two wheels being transversely mounted on chassis, and two connecting levers are separately fixed at rotating shaft two
End, two wheels are separately mounted on the free end of connecting lever, and also installation makes the drive mechanism of axis of rotation on chassis.
Compared to the prior art, the beneficial effects of the utility model are to improve the stability on caravan chassis, are specifically driven
Motivation structure makes axis of rotation, and rotating shaft drives the connecting lever on both sides to rotate, so under the drive of connecting lever, the wheel of connecting lever free end
Just rotate around the axis, wheel is relatively moved with respect to chassis, wheel can be moved to above chassis, chassis is directly implemented
On the ground, chassis and contact area of ground are improved, significantly improves the stability of caravan.
The utility model also does following improvement：
The drive mechanism includes at least one set of hydraulic cylinder and pivoted arm, and pivoted arm is fixed in rotating shaft, and hydraulic cylinder one end is hinged
On chassis, the other end is hinged on the free end of pivoted arm, and hydraulic cylinder extension drive shaft rotates.
The drive device includes two groups of hydraulic cylinders and rotating shaft, and two groups of hydraulic cylinders and rotating shaft are arranged in the two of chassis
Side.
At least one set of wheel group in addition is also installed, the pivoted arm in the rotating shaft of adjacent wheels group is connected with transmission arm on chassis.
The utility model additionally provides a kind of lift and pulls caravan chassis, including pulls caravan chassis wheel as previously described
Elevating mechanism.

Reference
1 pivoted arm, 2 connecting levers, 3 chassis, 4 wheels, 5 hydraulic cylinders, 6 bearings, 7 rotating shafts,
8 pivoted arms, 9 wheels, 10 transmission arms, 11 rotating shafts.
Embodiment
The utility model is elaborated with reference to the accompanying drawings and examples.
It should be noted that having symmetrical structure in view of the utility model, accompanying drawing is attached most importance to the side of symmetrical structure
Mark, is illustrated mainly in combination with the part of mark below.
With reference to Fig. 1 and Fig. 2, the wheel group being made up of rotating shaft 7 and two wheels 4, rotating shaft 7 is arranged on the chassis of caravan,
Such as Fig. 1, chassis 3 is represented with straight line, for explaining the relative position on chassis and wheel.Rotating shaft 7 is arranged on chassis, is such as schemed
2, bearing is installed respectively in the both sides of rotating shaft 7, such as the bearing 6 in left side, bearing is fixed on chassis.
In order that forming eccentric structure between wheel and rotating shaft, such as Fig. 1 and Fig. 2, connecting lever is fixed at the both ends of rotating shaft 7, such as
The connecting lever 2 in left side.The free end installing wheel 4 of connecting lever 2.The so axis rotation of the rotational band motor car wheel 4 of rotating shaft 7 around the shaft, makes
Relative movement is formed between wheel 4 and chassis.Wheel 4 supports on the ground, when the change of the distance between wheel and chassis is small, bottom
Relatively face has a downward action to disk 3, declines chassis.On the contrary, when rotating shaft 7 rotates backward, between wheel and chassis
Distance become big, relatively face has a upward action on chassis, raises chassis.In order to more fully understand This move mistake
Journey, can be the state that chassis rises with reference to Fig. 1 and Fig. 3, Fig. 1, Fig. 3 is the state that chassis declines.
Such as Fig. 1 and Fig. 2, in order to realize axis of rotation, pivoted arm 1 is installed in rotating shaft both sides, pivoted arm 1 and rotating shaft are rigidly connected,
One end of pivoted arm 1 and hydraulic cylinder 5 is hinged, and the other end of hydraulic cylinder 5 is hinged on chassis.When hydraulic cylinder 5 stretches, by pivoted arm
1, it can rotate rotating shaft 7, the drive mechanism of hydraulic cylinder 5 and the composition axis of rotation of pivoted arm 1.Such as Fig. 2, two groups are installed in the present embodiment
The combination of hydraulic cylinder and pivoted arm, in fact, one group can also be only installed, but the technological means Shortcomings are that stability is poor,
And in order to ensure that application dynamics is uniform, it usually needs installed in the centre position of rotating shaft 7, the bottom that can so influence caravan is empty
Between, cause space waste.
In addition, the effect of drive mechanism is to make the positive and negative rotation of rotating shaft 7, thus it is not limited to the group using hydraulic cylinder and pivoted arm
Close, the devices such as swivel hydraulic cylinder can also be used alone.
In view of the stability on caravan chassis, two groups of wheel groups can be mounted side by side, also further increase the load on caravan chassis
Lotus ability, such as Fig. 4 and Fig. 5, on the basis of original wheel group, increase what is formed by 11, two wheels 9 of rotating shaft and two connecting levers
Another wheel group.Connected between pivoted arm 8 and pivoted arm 1 in the wheel group with transmission arm 10, so when pivoted arm 1 rotates,
Drive pivoted arm 8 to rotate simultaneously, make the axis of rotation of the roller group where pivoted arm 8, realize wheel in the wheel group and chassis
Relative movement.Make four wheel synchronization actions, reach the purpose of the stable lifting in chassis.
