Description
Technical field
The present invention relates to Design of Tire Structure, and in particular to a kind of imitative ram's horn tire construction belongs to field of automobile parts and components.
Background technique
The unique parts that tire is contacted as automobile with road surface need good ground connection performance, to provide enough drives
Power, brake force and lateral force, to guarantee dynamic property, braking, control stability and the safety of vehicle.In existing car
In the design of tire, it is always insoluble problem that tire shoulder stress, which is concentrated, and the ground grip ability for promoting tire are always to study to learn
The research emphasis of persons.Car in motion, tire be easy to appear tire shoulder stress concentration, cause tire shoulder serious wear,
The problems such as service life reduction；In driving and braking, since the contact area of tire is small, so as to cause tire ground grip ability not
Foot, reduces the dynamic property and braking of tire.The tyre surface of tire is the mere contact position on tire and ground, for connecing for tire
Ground performance has important influence.
Cat passes through evolution in millions of years, and superpower adaptability is formd to external environment, and sole has reliable
Grasp performance.Studies have shown that cat on horizontal road surface when walking, sole can form good in a short time with ground
Contact, and its palm pad position pressure distributing homogeneity with higher, this grounding characteristics of ram's horn palm pad improve the fortune of cat
Dynamic flexibility, key are the special geometric shape of ram's horn palm pad.The geometry of ram's horn palm pad is divided into three parts, middle part
Dividing is regular strip convex curvature, and two sides are height lower than middle position and slightly convex strip curved surface, two side portions are closed
Symmetrical in middle position, three parts curved surface is smooth excessive.By observation, ram's horn palm pad transversal cross-section outer contour shape is one
The curve of rule, curve middle position are one section of raised circular arc, and curve two sides are similar to the tread arc of car tire tire shoulder position.
So ram's horn the palm pad this geometrical characteristic, can make the palm pad with ground formed it is good contact, generate biggish contact area,
And there is good ground contact pressure distribution uniformity.Therefore, the geometry of ram's horn palm pad is the ground connection performance of tyres for passenger cars
Raising provide Bionic Design foundation.
Summary of the invention
The technical problem to be solved in the present invention: in the case where tire often uses load and standard pressure, increase tire and driving and making
Contact area when dynamic, tire shoulder stress when reducing tyre rotation are concentrated, and the ground connection distributing homogeneity of tire is improved.
The technical solution adopted by the invention is as follows:
A kind of imitative ram's horn tire construction, which is characterized in that including tyre surface, band, belt, body piles, liner layer, tire
Side, triangle rubber, tyre bead and tyre bead periphery；The tyre surface, band, belt and liner layer press tire radial direction from outside to inside
It is sequentially arranged；The belt includes No.1 belt and No. two belts, is sequentially arranged from inside to outside by tire radial direction；
The tire tread form is imitative ram's horn palm pad geometry design；The tyre surface arc shape is designed to seven sections.
Further, the geometry of the ram's horn palm pad is the outer contour shape of ram's horn palm pad transversal cross-section.
Further, in the tyre surface, the horizontal length of seven segmental arcs be followed successively by from left to right 11.0mm, 17.5mm,
19.0mm, 92.0mm, 19.0mm, 17.5mm and 11.0mm.
Further, in the tyre surface, the radius of seven segmental arcs is from left to right successively are as follows: 88.0mm, 44.0mm,
200.0mm, 300.0mm, 200.0mm, 44.0mm and 88.0mm.
Further, in the tyre surface, the height of seven segmental arcs is from left to right successively are as follows: 0.5mm, 1.2mm, 0.25mm,
3.5mm, 0.25mm, 1.2mm and 0.5mm.
It further, is the connection that smoothly transits between seven segmental arcs in the tyre surface.
Compared with prior art, beneficial effects of the present invention:
(1) present invention makes tread geometry and ram's horn slap pad geometry close by redesigning tire tread；It is logical
It crosses simulation analysis to obtain, with compared with money conventional tyre, in the case where tire often uses load and standard pressure, imitates cat paw bucket wheel tire
Contact area is constant at tire shoulder, and intermediate position contact area increases, and increases contact area of the tire when freely rolling
5.1%, the contact area in driving and braking increases 8%, and the grip performance of tire is significantly improved.
(2) in the case where tire often uses load and standard pressure, possess imitative cat paw bucket wheel tire, make the earth contact pressure force value at tire shoulder
Significantly smaller, the earth contact pressure force value of ground plane middle section is opposite to be increased, and the pressure distribution in the entire ground plane of tire is more
Uniformly, solve the problems, such as that the tire shoulder stress collection of tire neutralizes serious wear；Maximum ground contact pressure when rolling tire freely
Value reduces 14.5%, reduces 15.4% in driving and maximum pround contact pressure force value when braking, the ground contact pressure distribution of tire
Uniformity is effectively improved, and tire wear performance is significantly improved.
