Description

A kind of electric vehicle PU solid wheels
Technical field
The utility model is related to electric vehicle tyre technical field more particularly to a kind of electric vehicle PU solid wheels.
Background technology
Existing tire for vehicles generally includes pneumatic tire and exempts to inflate solid tyre, and pneumatic tire is divided into there is inner tube of a tyre wheel Tire and tubeless tyre.
Tubed tyre is although cheap and damping performance is good, but easily by roughness pavement or pointed object Destruction, and the moment pricked just gas can have all been let out, if travel speed is very fast at this time, vehicle can be difficult control, it is especially right In the combination product that wheel footpath is smaller, movement velocity is higher, there is very big security risk.
Tubeless tyre is called vacuum tire, compared with tubed tyre, will not lose heart rapidly after being pierced through by foreign matter, peace Full property is higher, but its is expensive.In order to ensure the service life of vacuum tire and safety, the sizing material and enhancement layer of tire Thickness have to secure, since thickness is larger, for the smaller tire of wheel footpath, very big obstruction is had in production.
For the ease of trip, low-carbon environment-friendly, the electric vehicle of small portable, such as scooter and balance car, gradually by more Come pursuing for more people.Due to the wheel footpath very little of this small-sized electric car, being produced and used using the more difficult satisfaction of pneumatic tire will It asks.It is solid tire to exempt to inflate solid tyre i.e. carcass, simple in structure, it is easy to the tire of small-wheel-diameter to be made, and it is not afraid of It pricks tire, need not inflate, service life is long.However, PU solid wheels due to endogenous heat is serious and the thermal diffusivity of tire and wheel compared with Difference, for wheel at a high speed or under long-play, sizing material internal temperature will become very high;Prolonged high temperature can lead to PU tires Sizing material premature aging, tire are scrapped in advance.Although some sets heat emission hole to existing PU solid wheels in carcass, but heat emission hole In the presence of the intensity of reduction carcass that can to a certain extent, tire easily deforms in use for some time, and some even exists It cracks at heat emission hole, the extension of crackle eventually leads to scrapping for tire, reduces so as to cause wheel life, scraps in advance.How It is technical problem to be solved in the utility model to design the high electric vehicle PU solid wheels of a kind of perfect heat-dissipating, intensity.
Utility model content
The utility model in view of the deficiencies of the prior art, it is solid to provide the high electric vehicle PU of a kind of perfect heat-dissipating, intensity Wheel.
The utility model is realized by following technological means solves above-mentioned technical problem:
A kind of electric vehicle PU solid wheels including wheel rim and use the integrated poured molding carcass of polyurethane material, the tire Body is mounted on the outside of wheel rim, and there are one circular radiating channel and several straight heat dissipation channels for the interior setting of the carcass, described straight One end of shape heat dissipation channel is connected with circular radiating channel, and the other end of straight heat dissipation channel is connected with the inner wall of carcass, described The stabilizing bracket of annular is installed, the stabilizing bracket is hollow steel stabilizing bracket, and the straight radiates in circular radiating channel Steel pipe in channel is installed, is both provided with connecting the air hole of inner wall on the outer wall of the steel pipe and the outer wall of stabilizing bracket, it is described One end of steel pipe is connected with stabilizing bracket, and the other end of steel pipe is connected with wheel rim, and the wheel rim is in the junction position with steel pipe Heat emission hole is provided with, is interconnected between the steel pipe, stabilizing bracket and heat emission hole.
Preferably, a kind of electric vehicle PU solid wheels, the circular radiating channel, stabilizing bracket and carcass are concentric, The outer diameter of the stabilizing bracket is identical with the outer diameter of circular radiating channel.
Preferably, a kind of electric vehicle PU solid wheels, the cross section of the straight heat dissipation channel is circle, described The outer diameter of steel pipe is identical with the diameter of straight heat dissipation channel cross section, and the length of steel pipe and the length phase of straight heat dissipation channel Together.
Preferably, it is provided on the face of a kind of electric vehicle PU solid wheels, the carcass and ground contact anti-skidding convex It rises.
The utility model has the advantage of:The electric vehicle PU solid wheels of the utility model in carcass by setting heat dissipation logical Road greatly improves the heat dissipation performance of solid tyre, by installing the stabilizing bracket and steel pipe of steel in heat dissipation channel, significantly The intensity of solid tyre is improved, ensure that the service life of tire.
Further, the outer diameter of stabilizing bracket is identical with the outer diameter of circular radiating channel, and the support for playing stabilizing bracket is contributed to make With preventing squeegee action.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure diagram of the utility model carcass.
Fig. 3 is the schematic diagram of air hole on the utility model stabilizing bracket and steel pipe.
Specific embodiment
Purpose, technical scheme and advantage to make the utility model embodiment are clearer, new below in conjunction with this practicality Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched The embodiment stated is the utility model part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model Example, those of ordinary skill in the art's all other embodiments obtained without creative efforts, belongs to The range of the utility model protection.
A kind of electric vehicle PU solid wheels including wheel rim 1 and use the integrated poured molding carcass 2 of polyurethane material, described Carcass 2 is mounted on the outside of wheel rim 1, is set in the carcass 2 there are one circular radiating channel 3 and several straight heat dissipation channels 4, One end of the straight heat dissipation channel 4 is connected with circular radiating channel 3, the other end of straight heat dissipation channel 4 and the inner wall of carcass 2 Connection, is equipped with the stabilizing bracket 5 of annular in the circular radiating channel 3, and the stabilizing bracket 5 is hollow steel stabilizing bracket, institute Steel pipe 6 is installed in the straight heat dissipation channel 4 stated, be both provided with connecting on the outer wall of the steel pipe 6 and the outer wall of stabilizing bracket 5 in The air hole 7 of wall, one end of the steel pipe 6 are connected with stabilizing bracket 5, and the other end and wheel rim 1 of steel pipe 6 connect, the wheel rim 1 Heat emission hole 8 is provided in the junction position with steel pipe 6, is interconnected between the steel pipe 6, stabilizing bracket 5 and heat emission hole 8.
By installing stabilizing bracket and steel pipe respectively in circular radiating channel and straight heat dissipation channel, not only cause carcass Intensity does not reduce, also so that the non-deformability of carcass greatly enhances, since stabilizing bracket and steel pipe are hollow-core construction, and tube wall Upper setting air hole so that the heat-sinking capability of solid tyre greatly enhances, it is therefore prevented that carcass internal temperature is excessively high, ensure that carcass Service life.The electric vehicle PU solid wheels of the utility model greatly improve reality by setting heat dissipation channel in carcass The heat dissipation performance of heart tire by installing the stabilizing bracket and steel pipe of steel in heat dissipation channel, substantially increases solid tyre Intensity ensure that the service life of tire.
