Abstract

The utility model discloses a carcass composite piece for improving exposed lines in a tire, which comprises an airtight layer, a transition layer, a carcass, a carcass rubber sheet, a tire shoulder pad rubber, a tire crown, a tire sidewall and a carcass body rubber, the transition layer is paved on the airtight layer, the carcass is paved on the transition layer, the tire shoulder pad rubber is paved on the carcass and is positioned on the shoulder part of the tire, and the tire crown is paved on the tire shoulder pad rubber. The tire shoulder pad rubber is laid at the joint of the tire body and the tire shoulder pad rubber, the tire body rubber is arranged at the joint of the transition layer and the tire body and located at the tire shoulder, and the tire body rubber sheet is laid at the joint of the tire body and the tire shoulder pad rubber and located at the tire shoulder. The problems that gaps between tire body cord threads are increased, cord thread rubber materials are insufficient, and butyl rubber permeates into an air tight layer due to inflation shaping expansion are effectively solved, and when existing equipment is free of space transformation or capital is insufficient, the problem that threads are exposed in a tire due to the fact that the size and quality of half parts fluctuate, the Mooney viscosity of a transition layer is too low, and the assumed stretching value of the tire body cord threads is too large is effectively solved.

TECHNICAL FIELD

[0001] The utility model relates to a tire technical field especially relates to a tire body composite part that improves tire inside line. BACKGROUND

[0002] Tire is one of the most important components on the car, its role mainly has: support the whole weight of the vehicle, bear the load of the car, transmit the traction and the braking torsion, guarantee the adhesion of the wheel and the road, reduce and absorb the vibration and the impact force of the car when driving, prevent the severe vibration and the early damage of the automobile parts, adapt the high speed performance of the vehicle and reduce the noise when driving, guarantee the safety, the steering stability, the comfort and the energy saving economy of driving.

[0003] The existing tire structure is prone to tire inside line problems in the actual production process due to the size and mass fluctuation of semi-finished products, the excessively low mooney viscosity of the transition layer rubber, the excessively large assumed elongation of the tire body cord, the improper process parameter control during molding and the vulcanization process fluctuation, and therefore a tire body composite part that improves tire inside line is needed to meet the demand. UTILITY MODEL CONTENT

[0004] The utility model discloses a tire body composite part that improves tire inside line, which solves the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a tire body composite part that improves tire inside line, comprising an air tight layer, a transition layer, a tire body, a tire body rubber sheet, a shoulder pad rubber, a tire crown, a tire side and a tire body type rubber, the transition layer is laid on the air tight layer, the tire body is laid on the transition layer, the shoulder pad rubber is laid on the tire body and is located at the shoulder of the tire, the tire body type rubber is arranged at the connection between the transition layer and the tire body and is located at the shoulder of the tire, the tire body rubber sheet is laid at the connection between the tire body and the shoulder pad rubber and is located at the shoulder of the tire, the tire crown is laid at the upper end of the shoulder pad rubber, and the tire side is laid at the side end of the tire crown.

[0006] Preferably, the tire body type rubber adopts the same material as the transition layer, and the thickness, width and position of the tire body type rubber can be adjusted according to the needs to adapt to the use of different size specifications of the tire.

[0007] The utility model has the advantages of:

[0008] The utility model discloses a tire shoulder part thickness is improved indirectly through the setting of the tire body type glue, can effectively solve the tire manufacturing process, and the tire body cord interval becomes big that inflation setting expansion will cause, cord rubber material is not enough that butyl rubber of airtight layer penetrates into, and when the existing equipment has no space reformation or is insufficient in funds, effectively prevent the tire inside line exposure problem that appears because half part size and quality fluctuation, transition layer mooney viscosity is too low, tire body cord supposition extension value is too big etc. BRIEF DESCRIPTION OF DRAWINGS

[0009] Fig. 1 It is a tire shoulder part cross section structure schematic diagram of the tire body composite part of the utility model for improving tire inside line exposure;

[0010] Fig. 2 It is the tire body cross section development drawing of the tire body composite part of the utility model for improving tire inside line exposure.

[0011] In the drawing: 1, airtight layer;2, transition layer;3, tire body;4, tire body rubber sheet;5, tire shoulder pad rubber;6, crown;7, tire side;8, tire body type glue. DETAILED DESCRIPTION

[0012] The technical scheme in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments.

[0013] REFERENCE Figs. 1-2 A tire body composite part for improving tire inside line exposure, including airtight layer 1, transition layer 2, tire body 3, tire body rubber sheet 4, tire shoulder pad rubber 5, crown 6, tire side 7 and tire body type glue 8, its characterized in that: transition layer 2 is laid on airtight layer 1, tire body 3 is laid on transition layer 2, tire shoulder pad rubber 5 is laid on tire body 3, and is located in the shoulder of tire, tire body type glue 8 is set in the connecting place of transition layer 2 and tire body 3, and is located in the shoulder of tire, tire body rubber sheet 4 is laid in the connecting place of tire body 3 and tire shoulder pad rubber 5, and is located in the shoulder of tire, crown 6 is laid in the upper end of tire shoulder pad rubber 5, and tire side 7 is laid in the side end of crown 6.

[0014] Through the setting of tire body type glue 8, the thickness of tire shoulder part is improved indirectly, can effectively solve the tire manufacturing process, and the tire body cord interval becomes big that inflation setting expansion will cause, cord rubber material is not enough that butyl rubber of airtight layer penetrates into, and when the existing equipment has no space reformation or is insufficient in funds, effectively prevent the tire inside line exposure problem that appears because half part size and quality fluctuation, transition layer mooney viscosity is too low, tire body cord supposition extension value is too big etc.

[0015] Specifically, in the embodiment, the body type glue 8 adopts the same material as the transition layer 2, and the thickness, width and position of the body type glue 8 can be adjusted according to the requirements to adapt to the use of different size tires.
