As shown in Figures 1 and 2, the bench test device of tire of the present invention is (following, sometimes referred to as " device ") 1, be for indoor for car with, motorcycle with and be known as SUV(Sports Utility Vehicle) etc. the device tested of the rideability of various tires (below sometimes referred to as " the tire ") T that uses etc. of the four-wheel drive used of multipurpose automobile, wherein, rideability is such as comprising that noiseproof feature, turn performance, water float performance, polishing machine etc.
The device 1 of present embodiment is for example configured to and comprises: can be along the rotary drum 2 rotating in a circumferential direction; Bolster 3, this bolster 3 keeps tire T in the mode of cantilever, and the tread surface T1 that makes to be installed on the tire T of wheel rim J contacts and rotates on the inner peripheral surface 2G of rotary drum 2; Drive the tire driver element 4 of this bolster 3; Above-mentioned rotary drum 2 is remained to the drum rotating axle 5 that can rotate in the mode of cantilever; And the rotary drum driver element 6 that this drum rotating axle 5 is rotated to driving.Like this, the device 1 of present embodiment becomes the measurement mechanism of built-in rotary drum (inside drum) formula that tire T travels on the inner peripheral surface 2G of rotary drum 2.
The rotary drum 2 of present embodiment comprises: the inner peripheral surface 2G that possesses the simulated roadway 7 that imitates the road surface of using in real vehicle running test; The side 2A of one side of above-mentioned drum rotating axle 5 is installed; And the side 2B with the opposite side of the opening O passing in and out for tire T.In addition, the periphery at above-mentioned opening O is provided with highly less flange part Of.
As shown in Fig. 3 (a), above-mentioned inner peripheral surface 2G has to outstanding circular-arc the level and smooth 2M of rotary drum radial outside in the cross section that comprises drum rotating axle 2c.Inventor's experimental result can distinguish, as shown in Figure 4, and the ground connection shape approximation of the tire travelling on the ground connection shape of the tire travelling on this circular-arc 2M and the road surface in real vehicle running test.Therefore, act on the load of the ground plane of the tire travelling on circular-arc 2M, distribute approximate with the load that acts on the ground plane in real vehicle running test.Therefore, the bench test device of tire of the present invention, can obtain the test findings higher with travel performance test results relevance at the outdoor tire based on real vehicle carrying out.

And in the situation that carrying out noiseproof feature test, except the shape of the inner peripheral surface 2G of rotary drum 2, all take the monomer bench test method of JASOC606-8 defined and carry out as benchmark in other aspects.
Described, travel in operation, by driving and tire T is rotated to driving being installed on the motor 15 of bolster 3.And, utilize cylinder body 12 that bolster 3 is declined, utilize contact load control apparatus control load, for example under regular load load condition, make tire T ground connection on the equator Ca of the inner peripheral surface 2G of rotary drum 2.In addition, at this, travel in operation, preferably described water receiving cover 22 is not measured to the reflecting background of described water receiving cover 22 from installing 1 dismounting.
Described " regular load load condition " means, wheel rim is assembled in regular wheel rim and has filled the tire after regular interior pressure, applies the state of regular load.Wherein, described " regular wheel rim " refers to the wheel rim of stipulating this specification in the schematism of specification that comprises tire institute foundation according to each tire, if for example JATMA represents standard rim, if TRA represents " Design Rim ", if or ETRTO represent " Measuring Rim ".Described " regular interior pressure " refers to the air pressure of stipulating described specification according to each tire, if JATMA represents hyperbar, if TRA represents the maximal value of recording in form " TIRE LOAD LIMITS AT VARIOUS COLD INFLATION PRESSURES ", if ETRTO represents " INFLATION PRESSURES ", the next 200kPa that is made as of situation at tire for car.Described " regular load " refers to the load of stipulating described specification according to each tire, if JATMA represents " maximum load capability ", if TRA represents the maximal value of recording in form " TIRE LOAD LIMITS AT VARIOUS COLD INFLATION PRESSURES ", if ETRTO represents " LOAD CAPACITY ".

According to inventor's checking, can distinguish, the noise testing result that noise fest method based on this tire is carried out, (for this point, will in the embodiment below, be described in detail with the correlativity of the noise testing result of carrying out in real vehicle running test is very high.）。Therefore do not carry out outdoor real vehicle inertia traveling test and just can correctly evaluate the noise fest of tire T.
As other embodiments, there is the method for the polishing machine of measuring tire T.In this case, described, travel in operation, the motor 17 that is installed on the motor 15 of bolster 3 or is installed on drum rotating axle 5 is driven, make tire T contact rotation with the inner peripheral surface 2G of rotary drum 2.Then, in measuring operation, measure the of poor quality of tire T before and after the above-mentioned operation of travelling.In measuring operation, except by measuring the method for the quality of trying to achieve the tire T before and after travelling, also there are the tire wear break flour producing in driving process the method for measuring its quality etc. of collecting.The measurement of quality is used to known quality meter.
As alternate manner, also there is the method for the frictional behaviour of measuring tire.For example, by making the rotational speed V(km/h of rotary drum 2) from the rotational speed v(km/h of tire T) different, and the coefficientoffrictionμ while measuring tyre slip and the relation of skidding between rate S (following, be called " μ-S characteristic "), can evaluate above-mentioned frictional behaviour thus.The value of the coefficientoffrictionμ between tire T and simulated roadway 7, the rate of the skidding S during according to the braking shown in following mathematical expression 1, driving changes.
(mathematical expression 1)
During braking: the rate of skidding S(%)={ (V-v)/V} * 100%
During driving: the rate of skidding S(%)={ (V-v)/V} * 100%
Particularly, in the operation of travelling, rotary drum 2 and tire T are rotated with identical rotational speed, then, the speed of maintenance rotary drum 2 is constant and utilize described rotation speed control device so that the mode that the rotational speed of tire T is slowed down is gradually braked.Then, in measuring operation, by the friction force under force cell 2 these on-positions of output, calculate thus coefficientoffrictionμ and evaluate the tyre slip rate-friction factor characteristic while braking.In addition, can also make the rotational speed of tire T sharply decline and become only (full lock) state of full lock, and evaluate tyre performance by the coefficientoffrictionμ of calculating under this state.
In addition, the evaluation method during with above-mentioned braking is contrary, can also make the rotational speed of tire T accelerate gradually and become driving condition, evaluates thus the tyre slip rate-friction factor characteristic while driving.And then, can also make the rotational speed of tire T sharply rise and become vehicle wheel rotation state, thereby evaluate the tyre performance under this state.
