A kind of open flume type structure polyurethane hand cart tyre that will not be blown out
Technical field
The present invention relates to a kind of hand cart tyre, a kind of specifically open flume type structure polyurethane hand cart tyre that will not be blown out.
Background technology
Tire is the common name of tire, is generally made of abrasive rubber material, point for having solid tyre and air tyre.Air tyre by
The inner tube of a tyre and cover tire composition, the shortcoming of air tyre are that the elastomeric material of tyre surface is easy to wear, and secondly the inner tube of a tyre is due to being inflated supporting, also
Therefore there is the possibility blown out.And solid tyre of the prior art is there is also many defects, such as from which kind of material system
Make solid tyre, find that hand cart tyre is made using polyurethane material an extraordinary advantage under study for action later, such as wear-resisting,
Hardness is adjustable etc..
Applicant is applying for a series of patents on polyurethane hand cart tyre before, including the applying date is in November, 2009
29 Patent No. ZL200920274370.9 utility model patent, the Patent No. that the applying date is on December 28th, 2011
ZL201120578218.7 utility model patent and the applying date are that the number of patent application on December 28th, 2011 is
201110462022.6 application for a patent for invention, in the research and development of hand cart tyre, it is found that polyurethane open architecture hand cart tyre will be realized
Supportive, the handling harmony with comfortableness are a global problems at present.Such as the design of two-wheeled hand cart tyre
For plane tire structure, it is smaller to be installed on influence of the trailing wheel to traveling, but when being installed on front-wheel, because the planar structure of its front-wheel is in side
When inclining or turning, plane domain of the plane tire in inclination or turn direction side has the reaction force that a ground is given, i.e.,
Screen resilience, causes plane tire to have one in inclination or turn direction side and returns positive force, cause vehicle to rock and wave, so
It can be designed as far as possible from the curved surface tire close to conventional pneumatic in the tread design of hand cart tyre.But in actual experimentation
It was found that, based on the requirement of above-mentioned Patent design, curved surface polyurethane open architecture hand cart tyre is in test process, and vehicle can be with tire
The hardness of body casting and the decline for disturbing degree in the wrong, rock and wave in positive aggravation trend.
In experimentation, through test and the calculating of casting repeatedly, find the ring-type disc in above-mentioned Patent design in curved surface
In the case of tire stress, if polyurethane tyre body hardness is too low, ring-type disc produces compression or warpage first, and this point is in vehicle side
It is particularly evident when inclining or turning.First, the first stress point of curved surface tire tyre surface center of surface, and in the tire of center of surface point
It is ring-type disc between face dorsal part and wheel hub, when center of surface is as the first stress point, its ground reaction born
Power is preliminarily applied to the supporting plate of ring-type disc rather than ring-type disc both sides, if the now hardness foot of carcass and ring-type disc
Enough, such as hardness shore A 100, this hardness is generally proximate to a steel tire hardness, and now ring-type disc will not be produced
Any deformation and warpage, based on the construction of curved surface tire, now tire can complete straight trip, roll and excessively curved etc. all basic
Ride operation.But problem is that the ground plane of now tire is very small, the frictional force with ground is inadequate, braking distance extension, sideslip
Easily occur etc. phenomenon, while being judged completely without comfortableness with general knowledge, such a design can not be.
If reducing the polyurethane hardness of carcass, when center of surface is as the first stress point, the ground that it is born is anti-
Active force is preliminarily applied to ring-type disc, continues to apply carcass pressure, followed by remote close to the supporting plate of ring-type disc both sides
The supporting plate of ring-type disc both sides sequentially stress, carcass produces deformation, comfortableness and handling is improved therewith.But problem
It is, first the ring-type disc of stress, if with theoretical ideal smooth level ground and straight-line travelling, now at ring-type disc
In compressive state, it will not be produced in the ideal situation with the supporting plate of the impartial deformation in both sides and rock and wave.But, in vehicle side
When inclining and turning round, now ring-type disc and the stressing conditions of the supporting plate of the impartial deformation in both sides just produce change, roll and turn round
Direction supporting plate deformation aggravation, simultaneously as the non-perpendicular stress of ring-type disc and be changed to lateral force produce Bending Deformation, firmly
The relatively low ring-type disc of degree even produces warpage.Center of surface is also in the ideal situation the situation of maximum weighted point as first
In vehicle roll, it is excessively curved and other non-ideal straight trips ride in the case of be constantly changed, in these cases, ground is given
The reaction force of ring-type disc makes ring-type disc constantly produce the Bending Deformation or warpage of left and right, rocks or waves and thus produces.
