Abstract:
The present invention provides a pneumatic tire (100) with integrated envelope comprising, a tread (1), a belt system (2), and a tire casing (3), wherein said tire casing (3) comprises a side wall (4), a bead (5), a plurality of layer including but not limited to a carcass ply (6) acting as a top layer, an inner liner (7) acting as bottom layer and an envelope (8) that is sandwiched between said carcass ply (6) and the inner liner (7), said envelope (8) is injected with a fluid inside said tire casing (3) in which said tire casing (3) is pasted on said belt system (2) and said belt system (2) is pasted on said tread (1) in said pneumatic tire (100) and said side wall (4) protects said tire casing (3).
Abstract:
The present invention relates to a manufacturing process of envelope(s) integrated tubeless tyre. More specifically, the invention provides a manufacturing process for integrating envelope(s) to accommodate sealant, coolant, etc. in a tubeless tyre. The invention aims to provide a manufacturing process that overcomes the drawbacks and enables effective and efficient integration of envelope(s) to accommodate sealant, coolant, etc. in a tubeless tyre. The manufacturing process of envelope(s) integrated tubeless tyre is limited to high quality semi vulcanized tubeless tyres and envelope(s) made as per specification for undergoing further manufacturing processes. Though the rubber of the tyre and envelope(s) is semi-vulcanised and ready to use, still they are soft with some flowability for superior grip and further processing.
Abstract:
A Pneumatic Pressure Sensor (PPS) for vehicles comprising of means to sense the deformation in side walls or distance between wheel and crown portion of tyre; means to capture details of deformation or distance; and means for transmitting the same information to ECU which further sends signal to the dashboard after processing the same information. Said means to sense deformation or distance comprises of a flexible wire loop (7) of whose one end is fixed to a housing (5); said wire loop passes through supporting wire notch at the inner side of the crown portion of the tyre (8) and free end of said wire loop is passed through receptors (6) to capture details of deformation or distance. Sensors/transducers are provided at the side wall of the tyre where maximum deformation is possible.
Abstract:
A multi-chambered inner-part of tyre/tube (2) and manufacturing process for the same for vehicles comprising of at least one chamber (4) adjacent to the crown portion of the tyre (2) having a no-return inlet valve in the inner part of said chamber (4) to provide pressurized air to enter inside the chamber (4), at least one master chamber (3) adjacent to the rim (1) joined to one inlet of master valve, the said master valve having at least two outlets, one of which acts as the inlet for the said master chamber (3) and the other outlet supplying pressurised fluid to different chambers (4), the pressurised fluid is provided to all the chambers (3; 4) by separate no-return valves and in case of tube, chambers (4) other than master chamber (3) are provided with no-return outlet valves for maintenance purpose.
Abstract:
A multi-chambered tyre with or without pressure-loss sensor for vehicles comprising an inner tyre (2) and an outer tyre (1 ), wherein at least one chamber (8) adjacent to the crown portion of the outer tyre (1 ) having a separate no-return inlet valve (one way valve) (9) in the inner part of each chamber (8) to provide pressurized fluid to enter inside the chamber. The side walls of the chambers (10) are parallel to each other /parallel to each other and equidistance from each other/ parallel to each other along axial direction/parallel to each other along circumferential direction/parallel to each other along circumferential and axial direction /at a certain angle to each other along axial direction or along circumferential direction or along both axial and circumferential direction.
