Description
Technical field
The utility model belongs to automobile and trailer anti-splashing system, particularly relates to a kind of be adapted to automobile or trailer tyre
The dedicated curtain of rain of mud guard.
Background technique
Carrier road conditions in China's are more severe at present, and the main function of mud guard is the sand for effectivelying prevent adhering to by tire
Stone particle, rainwater splash everywhere；Protect the paint and metal plate of vehicle body.At present the material of state's inner fender be usually metal with it is non-
Metal material, processing technology include punching press, plastic uptake, SMC molding etc..Furthermore have a small number of using mud guard made of rubber, rubber
The mud guard of material is fixed on above subframe or chassis by mud cover support rod.Due to heavy truck work operating condition and
The particularity of form road conditions causes the service life of rubber fender to shorten dramatically, if will lead to using aluminum alloy material
Cost greatly improves.Therefore in the prevalence of power consumption of polymer processing height, product quality weight, transportation cost is high, and later period maintenance is at high cost
Problem；In addition existing fender structure can not prevent the sandstone of (especially when the vehicle is driving at high speed) wheel attachment very well
The splashing of grain and rainwater, sandstone particle and rainwater due to mud guard smooth interior surfaces, because accompanying by caused by wheel high speed rotation
Vehicular traffic and pedestrian are impacted without pop-up with part after mud guard collision.
For vehicle anti-splashing system in " automobile and trailer anti-splashing system performance and test method " (GB 34695-2017)
System structure, which proposes, to be distinctly claimed:
The system that tire splashes up water mist when anti-splashing system is for reducing vehicle movement.Anti-splashing system usually by
Mud guard, outer baffle, curtain of rain composition equipped with anti-splashing device.
Wherein anti-splashing device includes two types:
1, air/water divergence type device: a part of outer baffle and/or the curtain of rain is constituted, it can allow air to pass through, subtract simultaneously
Few water mist sputtering.
2, energy absorbing device: a part of mud guard, and/or outer baffle, and/or the curtain of rain is constituted, it can absorb water
Divide the energy of injection, to reduce water mist sputtering.
The curtain of rain is a kind of to be vertically mounted on wheel rear portion, the compliant member on chassis or loading platform lower part or mud guard.
The background technique that applicant is retrieved includes:
Application No. is a kind of automobile anti-splashing mud guard, including gear are disclosed in 201510322841.9 patent document
Mud plate ontology is provided with suppressing plate on mud guard ontology, and suppressing plate is arranged between wheel and mud guard, feature be suppressing plate with
Gap is provided between mud guard, gap forms runner, and multiple openings are provided in suppressing plate, and opening is connected with runner.On
The prior art is stated mainly by being provided with the suppressing plate of opening on mud guard ontology, and between mud guard ontology and suppressing plate
Gap is set, which forms runner, and muddy water, the grains of sand, stone of splashing etc. are entered in runner by opening, along runner stream
Out.The above-mentioned prior art has following defects that since protrusion unit surface is smooth and surface hardness is higher, when amount of rainfall is larger or
When person's speed is too fast, accompanying muddy water, sandstone particle can cannot be abundant by protrusion element because centrifugal force is larger on wheel
Energy is absorbed, anti-splashing effect is poor, and the sandstone particle of especially hard easily causes danger to vehicular traffic and pedestrian.
Application No. is a kind of vehicle mudguard is disclosed in 201480032873.9 patent document, it is related to through multiple holes
Rainy day (or snowy day) is excluded as traveling is on the ground (road) of ponding towards vehicle tyre rear with the save-all of matrix arrangement
Vehicle tyre the water (spray) that splashes of rotation so that can control generation spray, and can prevent from interfering traveling lane aside
Vehicle drive people sight, so as to the vehicle mudguard to try to avert accidents.The above-mentioned prior art have the following deficiencies: by
In using multiple aperture design principle, mud guard surface equally at smooth flat, encounter larger rainwater or wheel attachment rainwater,
When sandstone particle is more, because aperture is fixed and material surface hardness is higher, the effect for absorbing energy is poor, especially hard sandstone
Unordered splashing after particle can be collided with mud guard, and vehicular traffic and pedestrian are impacted, and noise is larger.
In view of the above problems, exploitation has the lower mud guard of noise under preferable anti-splashing effect and working condition dedicated
Not only those skilled in the art need the technical problem underlying solved to the curtain of rain, while also complying with industry technology under national standard and developing
Main way.
