Detailed Description
In order to make the objects, contents and advantages of the present invention clearer, the following description will make a detailed description of embodiments of the present invention with reference to the accompanying drawings and examples.
This embodiment proposes a tread pattern structure for a rubber belt track, as shown in fig. 1 to 3. The ground pattern structure comprises a ground plane 1, a side cambered surface 2, a drainage groove 3 and a resistance reducing groove 4.
The ground plane 1 is surrounded by a first straight side 5, an arc side 6 and two second straight sides. Wherein the first straight edge 5 is perpendicular to the direction of the vehicle speed; the arc edge 6 is arranged opposite to the first straight edge 5; two ends of the first straight edge 5 and the arc edge 6 are respectively connected through two second straight edges which are parallel to the direction of the vehicle speed. The diameter of the arc edge 6 is 2.5-3.5 times of the width of the crawler belt. The arc edges 6 can enable the width W2 of the two sides of the rubber belt type track landing plane 1 to be smaller than the width W1 of the middle part of the track, and can effectively reduce the soil rubbing area during steering, thereby reducing the lateral resistance of the ground. When the vehicle walks forwards, the arc edge 6 lands firstly, and the first straight edge 5 lands secondly, so that the land area of the rubber belt type track is increased along with the gradual increase of the load, the uniform distribution of the load is realized, and the impact and the vibration of the vehicle are reduced.
The side arc surfaces 2 are located on both sides of the ground plane 1, connected to the two second straight edges of the ground plane 1, and protrude to both sides in the track thickness direction. The radius of the side cambered surface 2 is more than or equal to half of the thickness of the crawler belt, so that the side resistance of the ground can be reduced.
The drainage channel 3 sets up on the surface of the plane 1 that lands, and the width is greater than 10mm, and the direction is 10 ~ 20 degrees with the vehicle direction of travel, and the degree of depth is not less than 10mm, can play the effect of drainage, also can play the effect of mud of arranging on muddy road surface to improve rubber belt formula track ground adhesive force, improve vehicle mobility. Simultaneously, water drainage tank 3's cross-sectional design is trapezoidal, and the outside opening is great, and the inboard opening is less, forms the inclination, can effectively reduce the condition emergence of stone card in water drainage tank 3.
The resistance reducing groove 4 is a notch formed on the side cambered surface 2, and the direction of the notch corresponds to the angle formed by the landing plane 1 and the shape of the side cambered surface 2. The maximum depth of the resistance reducing groove 4 is not less than 8 mm. The resistance reduction groove 4 can improve the lateral deformation capacity of the rubber belt type track. When the vehicle encounters a hard bulge during steering to cause the crawler belt to receive great lateral resistance, the resistance reduction groove 4 can effectively change the shape of the rubber belt type crawler belt to reduce the lateral resistance applied by the ground bulge, and can effectively reduce the risk of vehicle belt release.
By using the rubber belt type track ground pattern structure of the embodiment, when a vehicle turns, the side cambered surfaces 2 and the resistance reducing grooves 4 on the ground pattern of the rubber belt type track can reduce the lateral resistance of the ground, so that the vehicle turns more lightly and the maneuvering performance of the vehicle is improved.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
