Abstract
The invention relates to a tire tread with a concave bottom surface and a tire crown structure applying the same. A concave-convex type groove along the length direction of the tire tread is formed in the bottom surface of the tire tread with the concave bottom surface, the width of the concave-convex type groove is consistent with the width of a belt ply to be combined with the tire tread, and the shape of the concave-convex type groove is matched with the concave-convex shape of the top surface of the belt ply to be combined with the tire tread. The tire crown structure comprises the tire tread and the belt ply, wherein a belt ply with a top surface in the concave-convex shape which is of a layered overlaying structure is adopted as the belt ply, and the tire crown structure is characterized in that the tire tread with the concave bottom surface is adopted as the tire tread, the width of the concave-convex type groove in the bottom surface of the tire tread is consistent with the width of the belt ply, and the shape of the concave-convex type groove is matched with the concave-convex shape of the top surface of the belt ply. The tire tread with the concave bottom surface can reduce the tire tread deformation, shorten the rolling time, and can also well improve the gas trapping phenomenon at steps of the belt ply after rolling, raise the tire inspection qualified rate and prolong the service life.
Description
Technical field
The present invention relates to a kind of tire protector and application thereof, specifically a kind of bottom surface concave type wheel tire tread and apply its tire crown structure, belong to tire equipment technical field.
Background technology
Existing wheeled car, particularly Large freight load-carrying vehicle, they run quickly on express highway, should fast again safety but also energy-conservation, this just has higher requirement to the tire of load-carrying vehicle.Existing tire construction is made up of nine large foundations such as crown, sidewall, triangle, pad glue, inside liner, bracing ply, carcass, chafer and bead coils substantially, the key point affecting tire load carrying behaviour mainly contains 2 points: one is the crown structure of tire, and two is the cage construction (as bracing ply, carcass, chafer, bead coil) of tire and various material selection.In these 2, the crown structure of tire affects particular importance to tire load carrying behaviour, because the crown of tire is the bridge connecting ground and tyre framework material, crown reasonable in design can enable the tire application force that in use tyre surface is subject to ground evenly be delivered on tire belt and tire carcass, makes tire uniform stressed; Tire protector reasonable in design in addition can embody excellent adhesion value in actual use, Duola can hurry up, realizes high efficiency hauling operation.
Tyre crown is generally made up of tire protector, bracing ply and carcass plies, and tire protector end face arranges certain shape to adapt to the demand of different kinds of tyre decorative pattern, and tire protector bottom surface and bracing ply end face will adopt forming roll pressing on forming machine.But in current each tyre production enterprise, the bottom surface of tire protector is plane, and bracing ply adopts stratiform overlaying structure, end face is concaveconvex shape, tire protector and bracing ply merge for reaching gapless, need to apply roll extrusion that the is powerful and long period to tire protector, make tire protector bottom surface produce huge distortion to adapt to the concaveconvex shape of bracing ply end face below.There is following defect in above array configuration: 1, tire protector distortion is large, and tire protector bottom surface deflection is uncontrollable, and needs the roll extrusion of long period in actual production process; 2, often occur that gap exists at the step place tire protector rolling process of bracing ply superposition, the air in these gaps can become bubble after tyre vulcanization, becomes the origination point that tire destroys.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of bottom surface concave type wheel tire tread is provided and applies its tire crown structure, described bottom surface concave type wheel tire tread can not only become the bracing ply of concaveconvex shape to match better with end face, reduce tyre surface distortion, shorten the roll extrusion time, and deposit gas phenomenon after the roll extrusion at bracing ply step place can being improved very well, improve tire inspection qualification rate and service life.
According to technical scheme provided by the invention: bottom surface concave type wheel tire tread, it is characterized in that: the bottom surface of described tire protector is provided with the concave-convex type groove along tire protector length direction trend, the width of described concave-convex type groove with will be consistent with the width of the bracing ply that tire protector combines, the shape of concave-convex type groove matches with the concaveconvex shape of the end face of the bracing ply that will combine with tire protector.
As a further improvement on the present invention, described concave-convex type groove is provided with at least single order recess step and single order central protuberance step by trough rim successively to center, the quantity of described recess step and shape and the quantity of the side raised step of the end face side of bracing ply that will combine with tire protector and form fit.
A kind of tire crown structure, comprise tire protector and bracing ply, described bracing ply adopts the end face of stratiform overlaying structure to be the bracing ply of concaveconvex shape, it is characterized in that: described tire protector adopts above-mentioned bottom surface concave type wheel tire tread, the width of the concave-convex type groove of described tire protector bottom surface is consistent with belt width, and the shape of concave-convex type groove and the concaveconvex shape of bracing ply end face match.
compared with prior art, tool has the following advantages in the present invention:bottom surface of the present invention concave type wheel tire tread can not only become the bracing ply of concaveconvex shape to match better with end face, reduce tyre surface distortion, shorten the roll extrusion time, and deposit gas phenomenon after the roll extrusion at bracing ply step place can being improved very well, improve tire inspection qualification rate and service life.
Accompanying drawing explanation
Fig. 1 is the constructional drawing of embodiment of the present invention bottom surface concave type wheel tire tread.
Fig. 2 be in Fig. 1 bottom surface concave type wheel tire tread and bracing ply combine before constructional drawing.
Fig. 3 is the constructional drawing that in Fig. 1, bottom surface concave type wheel tire tread and bracing ply, carcass plies are combined into crown.
Detailed description of the invention
The invention will be further described to combine concrete drawings and Examples below.
As shown in the figure: Fig. 1 is a kind of bottom surface concave type wheel tire tread, the bottom surface of this tire protector 1 is provided with the concave-convex type groove along tire protector 1 length direction trend, and described concave-convex type groove is provided with two rank recess step 1a and single order central protuberance step 1b by trough rim successively to center.
Fig. 2 be bottom surface concave type wheel tire tread 1 and will with the bracing ply 2 of its combination, as seen from Figure 2, the width of the concave-convex type groove of described tire protector 1 bottom surface is consistent with the width of bracing ply 2, and the concaveconvex shape of the shape of concave-convex type groove and the end face of bracing ply 2 matches.
Fig. 3 is a kind of tire crown structure, it mainly comprises tire protector 1, bracing ply 2 and carcass plies 3, described bracing ply 2 adopts the end face of stratiform overlaying structure to be the bracing ply 2 of concaveconvex shape, described tire protector 1 adopts the bottom surface concave type wheel tire tread in Fig. 1, the width of the concave-convex type groove of described tire protector 1 bottom surface is consistent with bracing ply 2 width, and the shape of concave-convex type groove and the concaveconvex shape of bracing ply 2 end face match.
By adopting this bottom surface concave type wheel tire tread, not only greatly reducing tire protector 1 and being out of shape, shortening the roll extrusion time, improve tire production efficiency, and improve and deposit gas phenomenon after the place's roll extrusion of bracing ply 2 step, improve tire inspection qualification rate and service life.
