Description
Technical field
The present invention relates to a kind of hand cart tyre, specifically a kind of polyurethane hand cart tyre of not blowing out with buffer gear.
Background technology
Tire is the common name of tire, usually makes with antifriction rubber material, have solid tyre and air tyre point.Air tyre is made up of the inner tube of a tyre and cover tire, and the shortcoming of air tyre is that the elastomeric material of tyre surface is easy to wear, and secondly the inner tube of a tyre is owing to being inflated supporting, also therefore there is the possibility of blowing out.And solid tyre of the prior art also also exists many defects, such as, select which kind of material to make solid tyre, find that adopting polyurethane material to make hand cart tyre has extraordinary advantage afterwards under study for action, such as wear-resisting, hardness adjustable etc.
Applicant is applying for a series of patent about polyurethane hand cart tyre before, to comprise the applying date be the patent No. in November 29 in 2009 is the utility model patent of ZL200920274370.9, the utility model patent of the applying date, to be the patent No. on December 28th, 2011 be ZL201120578218.7 and the applying date are the number of patent application on December 28th, 2011 is the application for a patent for invention of 201110462022.6, in the research and development of hand cart tyre, find that polyurethane open architecture hand cart tyre will realize supportive, handling be a global difficult problem with the harmony of traveling comfort current.As two-wheeled hand cart tyre is designed to plane tire structure, be installed on trailing wheel less on the impact travelled, but when being installed on front-wheel, because the planar structure of its front-wheel is when rolling or turn, plane tire is at the antagonistic force rolled or the plane domain of turn direction side has a ground to give, i.e. screen resilience, cause plane tire to have one in inclination or turn direction side and return positive force, the curved surface tire close to conventional pneumatic causes vehicle to rock and waves, so can be selected in the tread design of hand cart tyre to design as far as possible.But find in the experimentation of reality, based on the requirement of above-mentioned Patent design, curved surface polyurethane open architecture hand cart tyre is in test process, and vehicle along with the hardness of carcass casting and can disturb the decline of bending degree, rocks and waves and aggravate trend in forward.
In experimentation, through repeatedly casting test and calculating, find that ring-type disc in above-mentioned Patent design is when curved surface tire is stressed, if polyurethane tyre body hardness is too low, first ring-type disc produces compression or warpage, and this point is particularly evident when vehicle roll or turning.First, first stress point of curved surface tire is at the center of surface of tyre surface, and be namely ring-type disc between the tyre surface dorsal part and wheel hub of center of surface point, when center of surface is as the first stress point, first its ground reaction force born is applied to the stay bearing plate of ring-type disc instead of ring-type disc both sides, if now the hardness of carcass and ring-type disc is enough, such as hardness shore A100, this hardness is generally proximate to a steel tire hardness, now ring-type disc can not produce any deformation and warpage, based on the structure of curved surface tire, now tire can complete and such as keep straight on, roll and all operations of substantially riding such as excessively curved.But problem is that the ground plane of now tire is very little, inadequate with the friction force on ground, the phenomenons such as braking distance prolongation, sideslip very easily occur, and do not have traveling comfort completely simultaneously, and judge with general knowledge, this kind of design not can be.
If reduce the polyurethane hardness of carcass, when center of surface is as the first stress point, first its ground reaction force born is applied to ring-type disc, continue to apply pressure to carcass, the stay bearing plate of next-door neighbour ring-type disc both sides, then the stay bearing plate away from ring-type disc both sides is stressed in turn, and carcass produces deformation, traveling comfort and handlingly thereupon to improve.But problem is, first stressed ring-type disc, if with the smooth level ground of theoretical ideal and straight-line travelling, now ring-type disc is in compressive state, can not produce in the ideal situation rock and wave with the stay bearing plate of the impartial deformation in both sides.But, at vehicle roll and when turning round, the stressing conditions of the stay bearing plate of the now impartial deformation of ring-type disc and both sides just produces change, the stay bearing plate deformation aggravation in inclination and direction of turning round, simultaneously because ring-type disc is non-perpendicular stressed and change lateral force into and produce Bending Deformation, the ring-type disc that hardness is lower even produces warpage.Center of surface in the ideal situation as first be also maximum weighted point situation vehicle roll, cross curved and other imperfect craspedodromes situation of riding under constantly changed, in these cases, the antagonistic force that ground gives ring-type disc makes ring-type disc constantly produce Bending Deformation or the warpage of left and right, rocks or wave to produce thus.
