Abstract
The invention provides a caterpillar traveling mechanism, which comprises a driving wheel, a driven wheel, a caterpillar, a supporting wheel, a driving shaft, a driven shaft and a support. The support is connected with a framework, the driving wheel is mounted on the driving shaft, the driven wheel and the supporting wheel are connected with the driven shaft, the caterpillar is arranged on the wheels in a covering manner, a dragging wheel is additionally disposed at one end, which is close to the outer side of a machine, of each shaft, and the caterpillar can be disposed on the dragging wheels in a covering manner. The caterpillar traveling mechanism is characterized in that each dragging wheel is a combination wheel and consists of two small wheels, and the axle centers of the small wheels and the axle center of the corresponding dragging wheel form three vertexes of a regular triangle. The caterpillar traveling mechanism has the advantages that the combination wheels replace integrated dragging wheels, weights of the dragging wheels are further lightened, grounding points are increased, unit pressure of ground connection is reduced, and the operation range of a machine is increased.
Description
Technical field
The invention belongs to the vehicle track technical field, especially relate to a kind of creeper undercarriage.
Background technology
In the prior art, the wheeled driving of the general employing of family's vehicle and common transport vehicle is to reach the purpose of light fast traffic.The general car body of engineering truck is big, and tonnage is heavy, and conventional tyre is difficult to bear so big pressure, and be difficult to satisfy in the wasteland, the hauling operation requirement in zones such as grassland, beach.Therefore, engineering trucks such as crane, bulldozer generally adopt track propulsion, to adapt to abominable surface condition.General crawler belt can only carry out work under the hard place operating mode of (or soil adds stone), and when we will carry out operation under softer operating mode, this crawler belt was with not competent.Therefore developing the little creeper undercarriage of grounding pressure extremely is necessary.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of creeper undercarriage is provided.
Technical scheme of the present invention is: a kind of creeper undercarriage, comprise driving wheel, flower wheel, crawler belt, caterpillar wheel, axle drive shaft, driven shaft, support, and support is connected with frame; Driving wheel is installed on the axle drive shaft; Flower wheel is connected with driven shaft with caterpillar wheel, and crawler belt is covered on each wheel, sets up one near an end in the body outside and drags wheel at each; Said crawler belt can be covered in and respectively drag on the wheel; It is characterized in that: the said wheel that drags is made up of two steamboats for combination wheel, three summits of the axle center of said steamboat and the axle center composition equilateral triangle that drags wheel.
Further, said steamboat is anodontia disc structure.
Advantage and good effect that the present invention has are: owing to use the wheel that drags of the alternative one of combination wheel, further reduced to drag the weight of wheel, increased earth point, reduced grounding pressure, increased mechanical scope of work.

Fig. 1 is the prior art constructions scheme drawing;
Fig. 2 is a structural representation of the present invention;
Fig. 3 is the structural representation that drags wheel.
Among the figure:

The specific embodiment
Like Fig. 1, shown in 2, a kind of creeper undercarriage of the present invention comprises driving wheel 6, flower wheel 1, crawler belt 7, caterpillar wheel 5, axle drive shaft 2, driven shaft 4, support 3; Support 3 is connected with frame; Driving wheel 6 is installed on the axle drive shaft 2, and flower wheel 1 is connected with driven shaft 4 with caterpillar wheel 5, and crawler belt 7 is covered on each wheel; Set up one near an end in the body outside and drag wheel 8, said crawler belt 7 can be covered in and respectively drag on the wheel 8 at each.Said drag wheel 8 for anodontia disc structure and with its place axle on other take turns big or small consistent, respectively drag and take turns 8 and arrange in a straight line.
As shown in Figure 3, dragging wheel 8 is a combination wheel, is made up of three summits of the axle center of steamboat 9 and the axle center composition equilateral triangle that drags wheel two steamboats 9.Use combination wheel can alleviate the weight that drags wheel on the one hand, increase the earth point that drags wheel simultaneously, be increased to two earth points, further reduced the ground connection ratio on the whole from an earth point.
During walking, drive axle drive shaft 2 by actuating unit on the frame and rotate, axle drive shaft 2 drives driving wheel 6 and rotates, and the crawler belt 7 that driving wheel 6 orders about on it rotates, and crawler belt 7 drives flower wheel 1, caterpillar wheel 5 again and drags wheel 8 and rotates.Drag wheel 8 owing to increased by a row, thereby widened the width of crawler belt 7, increased body and ground-surface area of contact greatly, reduced grounding pressure.
When with common crawler belt, can only under the hard place operating mode of (or soil adds stone), carry out work.If under softer operating mode, carry out operation, this crawler belt is with not competent.(answer left-right symmetric to install during installation) when having used new crawler belt, can under softer operating mode, carry out operation, such as all carrying out work under the operating mode on marshy area and mire ground.Enlarged mechanical range of use like this.
More than one embodiment of the present of invention are specified, but said content is merely preferred embodiment of the present invention, can not be considered to be used to limit practical range of the present invention.All equalizations of doing according to application range of the present invention change and improve etc., all should still belong within the patent covering scope of the present invention.
Claims (2)
1. a creeper undercarriage comprises driving wheel, flower wheel, crawler belt, caterpillar wheel, axle drive shaft, driven shaft, support, and support is connected with frame; Driving wheel is installed on the axle drive shaft; Flower wheel is connected with driven shaft with caterpillar wheel, and crawler belt is covered on each wheel, sets up one near an end in the body outside and drags wheel at each; Said crawler belt can be covered in and respectively drag on the wheel; It is characterized in that: the said wheel that drags is made up of two steamboats for combination wheel, three summits of the axle center of said steamboat and the axle center composition equilateral triangle that drags wheel.
2. creeper undercarriage according to claim 1 is characterized in that: said steamboat is anodontia disc structure.
