Description

Tyre side-wall impact test device
Invention field
The present invention relates to device that the sidewall impact resistance of tire is tested, relate to the tyre side-wall impact test device that tire is applied load and camber angle and may command impulsive force size in more detail.
Background technology
Because in the road up train, so tire can be subjected to various damages because of the state difference of road, this is because any barriers such as the nail on the road, stone fragment, glass all are the materials harder than the rubber of tire.
In addition, tire only could keep the sufficient life-span with the corresponding atmospheric pressure state of load, thus more than suitable air pressure or following state drive a vehicle and also can cause accident.
The major accident of tire is owing to multiple reason such as crack (Crack), inordinate wear, separation (Separation), concussion fracture produces.For this reason, manufacturing firm applies various variations in order to deal with the accident of tire to tire, has carried out multiple tire test.
In this tyre testing apparatus, representative impact test apparatus is the test unit of introducing among the SAE J1981 " Road hazard impact test for tire assemblies (the pavement damage shock-testing of tyre assembly) ".This test unit is the assembly that makes tyre and rim in halted state from just adding impact in the face of tire, the device that judgement could damage the Outer Tyre face.
But it is effective not enough that above-mentioned test unit is considered to.Its reason is that when tire has an accident because of impact, the barrier as the stone of rank, roadside on the road will be attacked the sidewall of tire.That is the position that, damages on tire and the state of tire (can not load and keep the flare angle) are different with actual situation.
The tread that contacts with the road surface part of tire is owing to comprising tread rubber and steel belt layer, so hardly can be destroyed because of impact.But, barrier is arranged on the road surface, perhaps when the like that highly different road surface up train of the rank, roadside of road stone, the side wall portion of tire is had impact.As shown in Figure 2, the sidewall 1a of tire 1 might be damaged.
Summary of the invention
The present invention be directed to above-mentioned problem proposes.Its purpose is to provide a kind of tyre side-wall impact test device, for tire under average operating because outstanding position such as rank, the roadside stone of road and the sidewall that damages easily, estimate the performance of its anti-impact force.
In order to achieve the above object, tyre side-wall impact test device of the present invention comprises: keep platform, utilize to keep platform that the subjects tire is connected fixed part on wheel rim (rim) assembly, load pressurization part to the tire application of load, detection applies the load test section of load to tire from this load pressurization part, the side wall portion of tire is applied the impact portion of impact, the level that is provided with of jointed shaft of the axle that dangles by above-mentioned impact portion keeps platform, a moving part that dangles that makes impact portion keep platform to move from above-mentioned level, be used to tangle the switch portion of the wheel on the above-mentioned impact portion, and for the control part that electric wire is connected that passes through to above-mentioned tire control camber angle and load value and on the tire fixed part and the test section of loading.
Description of drawings
Fig. 1 is the synoptic diagram of expression tyre side-wall impact test device of the present invention;
Fig. 2 is the local figure of the tire of the side wall portion state of breakage on the common tire of expression.
Most preferred embodiment
Describe the present invention with reference to the accompanying drawings in detail.
Fig. 1 is the figure of expression tyre side-wall impact test device of the present invention.
The formation of tyre side-wall impact test device of the present invention comprises: keep platform 2, by keeping platform 2 that subjects tire 1 is connected fixed part 3 on the wheel rim assembly, load pressurization part 4 to tire 1 application of load, detection applies the load test section 5 of load to tire 1 from this load pressurization part, the side wall portion 1a of tire 1 is applied the impact portion 6 of impact, the level that axle 7 the jointed shaft 8 that dangles by impact portion 6 is provided with keeps platform 9, the moving part 10 that dangles that keeps platform 9 to move from level impact portion 6, be used to tangle the switch portion 12 of the wheel 11 on the above-mentioned impact portion 6, and control part 14 for above-mentioned tire 1 control camber angle and load value are connected by electric wire 13 on the tire fixed part 3 and the test section 5 of loading.
The following describes the principle of work of the tyre side-wall impact test device of the present invention of above-mentioned formation.At first, with subjects tire 1 with the state of wheel rim assembling under be fixed on the fixed part 3.In order to apply specified test condition, utilize control part 14, fixed part 3 and load pressurization part 4 are moved shown in the arrow A of Fig. 1 and B, make tire 1 have camber angle (camber) and tire 1 is applied load.
Like this, the sidewall 1a of above-mentioned tire 1 is different because of air pressure, camber angle and load, becomes the state of compression and stretcher strain.
On the other hand, because tire 1 is applied impact, the impact portion 6 that is suspended on the axle 7 that dangles is moved by the moving part 10 that dangles.If the wheel 11 of this impact portion 6 is fixed on the switch portion 12 set on the level maintenance platform 9, then above-mentioned impact portion 6 becomes the free-falling state of preparing.
Then, if open the switch portion 12 that above-mentioned level keeps platform 9, then impact portion 6 is a fulcrum with jointed shaft 8, rotates in free-falling mode by the direction of arrow C of Fig. 1, thereby the sidewall 1a of tire 1 is hit.
Then, in order to estimate the interior impulsive force of above-mentioned sidewall 1a,, can judge that the impact to tire could damage by to the visual analysis of the sidewall 1a of tire 1, and air pressure inspection.
As mentioned above, tyre side-wall impact test device of the present invention, by to prior art the shock resistance of the sidewall that can not estimate estimate, finally can obtain the effect that the performance that makes tire is improved.
