Description
Technical field
The utility model relates to heavy duty tire, specifically a kind of carcass ply end construction.
Background technology
Along with the development of tire science and technology, tire safe capability more and more comes into one's own.Minimizing accident possibility occurrence is put in the first place in TBR tire (all-steel radial tyre) design.And on TBR tire, tyre bead bead because the end of carcass ply and steel wire heel fabric be subject to tire internal motion impact and there is large motion, be Frequent Accidents position.
Summary of the invention
The utility model, for the problems referred to above, provides a kind of carcass ply end construction, adopts this end construction can effectively improve load-carrying capacity and the service life of tire.
According to the technical solution of the utility model: a kind of carcass ply end construction, it is characterized in that: comprise upper triangular part and lower triangular part that end is closely abutted together, the below of described lower triangular part is provided with bead coil, on the excircle of bead coil, be coated with a circle bead ring wrapper, the border that carcass ply forms along upper triangular part, lower triangular part, bead coil three arranges, and arc-shaped surface laminating in described carcass ply bottom is provided with steel wire heel fabric; Inside liner and wheel rim protect glue and are arranged at respectively described steel wire heel fabric both sides, described wheel rim protects between glue and steel wire heel fabric and is provided with nylon heel fabric, described nylon heel fabric upper end extends to the side place of triangular part, between described nylon heel fabric and described upper triangular part, carcass ply and steel wire heel fabric, form space, in described space, be filled with carcass selvedge portion type adhesive tape; Described wheel rim protects and between glue upper end and nylon heel fabric, is provided with rim of the mouth and protects glue, and sidewall laminating is arranged at described rim of the mouth protects the outside of glue.
As further improvement of the utility model, the upper outside that described lower sidewall fits in wheel rim protects glue.
As further improvement of the utility model, described rim of the mouth is protected glue upper inner and is fitted with the surface of upper triangular part and carcass ply successively, and rim of the mouth is protected upper/lower terminal outside glue and protected glue and fit with sidewall, wheel rim respectively.
As further improvement of the utility model, the lower end of described inside liner is arranged at wheel rim protects the inner side of glue lower end.
As further improvement of the utility model, described carcass ply both sides are respectively higher than the steel wire heel fabric of corresponding side, and the boss of described carcass selvedge portion type adhesive tape is resisted against respectively the end of described steel wire heel fabric, the corresponding side of carcass ply.
Technique effect of the present utility model is: the utility model product structure is simple, reasonable in design, can effectively solve the phenomenon that the easy breach in drop center portion position easily comes to nothing, load-carrying capacity and the service life of tire are improved, reduce the bad probability of occurrence such as finished product tire position bubble class, improved the qualification rate of finished product tire.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further described.
In Fig. 1, comprise that carcass ply 1, steel wire heel fabric 2, inside liner 3, bead coil 4, bead ring wrapper 5, wheel rim protect glue 6, nylon heel fabric 7, lower triangular part 8, upper triangular part 9, carcass selvedge portion type adhesive tape 10, rim of the mouth and protect glue 11, sidewall 12 etc.
As shown in Figure 1, the utility model is a kind of carcass ply end construction, comprise upper triangular part 9 and lower triangular part 8 that end is closely abutted together, the below of described lower triangular part 8 is provided with bead coil 4, on the excircle of bead coil 4, be coated with a circle bead ring wrapper 5, the border that carcass ply 1 forms along upper triangular part 9, lower triangular part 8, bead coil 4 threes arranges, and described carcass ply 1 bottom arc-shaped surface laminating is provided with steel wire heel fabric 2; Inside liner 3 protects glue 6 with wheel rim and is arranged at respectively described steel wire heel fabric 2 both sides, described wheel rim protects between glue 6 and steel wire heel fabric 2 and is provided with nylon heel fabric 7, described nylon heel fabric 7 upper ends extend to the side place of triangular part 9, between described nylon heel fabric 7 and described upper triangular part 9, carcass ply 1 and steel wire heel fabric 2, form space, in described space, be filled with carcass selvedge portion type adhesive tape 10; Described wheel rim protects and between glue 6 upper ends and nylon heel fabric 7, is provided with rim of the mouth and protects glue 11, and sidewall 12 laminatings are arranged at described rim of the mouth protects the outside of glue 11.
The upper outside that 12 bottoms, described sidewall fit in wheel rim protects glue 6.
Described rim of the mouth is protected glue 11 upper inner and is fitted with the surface of upper triangular part 9 and carcass ply 1 successively, and rim of the mouth is protected glue 11 outside upper/lower terminals and protected glue 6 with sidewall 12, wheel rim respectively and fit.
The lower end of described inside liner 3 is arranged at wheel rim protects the inner side of glue 6 lower ends.
Described carcass ply 1 both sides are respectively higher than the steel wire heel fabric 2 of corresponding side, and the boss of described carcass selvedge portion type adhesive tape 10 is resisted against respectively the end of described steel wire heel fabric 2, the corresponding side of carcass ply 1.
The carcass ply end construction that the utility model provides, by being set in carcass ply anti-package distal portion, carcass selvedge portion type adhesive tape 10 fills the space occurring because of carcass ply 1 and steel wire heel fabric 2 end offsets, prevent the breach at rim line position, alleviating the stress that carcass ply 1 anti-package end causes because of stiffness change sharply concentrates, and absorb wheel rim position because the stress energy of the steel wire rotary torque that bent rich stress causes, thereby improve resistance to the coming to nothing property of carcass ply anti-package end, improve tire safe capability.
In actual production process, because the filling of carcass selvedge adhesive tape has reduced carcass ply and gas possibility is deposited in steel wire heel fabric end, reduce finished product tire wheel rim position bubble badness probability of occurrence.
