Abstract
The utility model discloses a rolling resistance testing device of tyre testing machine, which is provided for overcoming disadvantages that when testing the rolling resistance of tyres currently, a torque transducer is installed between an output shaft and a rotary drum shaft of a driving device of a testing machine to test torque value, then the torque value is converted to the testing data of the rolling resistance value, which is unreliable. The rolling resistance testing machine comprises a rotary drum, a hydraulic motor which is connected with a rotary drum shaft, a wheel rim shaft for installing a tyre, and a push plate which is connected with a piston rod of a hydraulic cylinder, wherein one end of a torque arm which is transversely arranged is fixed on a shell of the hydraulic motor, and the other end of the torque arm is connected with the lower end of a force transducer, and the upper end of the force transducer is provided with a stand which is arranged on one side of the hydraulic motor. As the torque arm which is fixedly connected with the shell of the hydraulic motor is connected with the force transducer, the hydraulic motor overcomes the friction between the tyre and the rotary drum and drives the rotary drum to rotate, the force transducer can directly detect the required torque value, the detected value does not need conversion, and can completely and correctly reflect the rolling resistance of the tyre, and the testing data is reliable.
Description
Technical field
The utility model belongs to test mechanical, and is specifically a kind of on tyre tester, tire carried out the device of resistance to rolling performance test.
Background technology
Before the research and development and the vehicle tyre of each batch of going into operation, all will produce the tire sample earlier, then sample be carried out the simulated roadway test of travelling, for example travel speed of tire test, durable test etc. are to guarantee the safe, reliable of vehicle '.
Tire is carried out the resistance to rolling test, prior art is carried out on tyre tester, the structure of testing machine comprises: be supported on the rotary drum that is driven by driving arrangement on the testing machine fuselage, and the wheel rim axle of support vehicle wheel rim, the periphery of rotary drum is the simulated roadway face, the output shaft of driving arrangement and rotary drum back shaft are equipped with torque sensor between the diaxon on same axial line.When doing test, earlier tire is installed on the wheel rim, the periphery of tire is leaned against on the periphery of rotary drum, promotion wheel rim axle makes tire rely on the simulated roadway face in the drum commentaries on classics and applies certain pressure, the driving rotary drum rotates, friction force is rolled tire on the simulated roadway face, at this moment, torque sensor promptly demonstrates the size of driving torque, obtains the resistance to rolling of tire through converting.But in the time will on same chaptrel tire testing machine, doing other and not needing with torque sensor, as the high speed of tire and long duration test, because torque sensor is connected on the rotary drum axle, so torque sensor is just being worked always, unnecessary like this use, make the normal shortening in serviceable life of torque sensor, damage easily.
The utility model content
Technical problem to be solved in the utility model is, overcome prior art tire is carried out the resistance to rolling test, employing is at the testing machine driving arrangement of existing band high speed and long duration test, the torque sensor of installing between output shaft and the rotary drum axle can not be thrown off, unnecessary always working makes the flimsy shortcoming of torque sensor, and a kind of resistance to rolling proving installation of tyre tester is provided.
In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: the rotary drum that its periphery simulated roadway road surface is installed in the fuselage upper support of testing machine, the output shaft of drive unit is connected with the rotary drum axle, the wheel rim axle that tire can be installed is parallel with the rotary drum axle, support and be installed on the slide unit of fuselage, and the piston rod of hydraulic cylinder is being connected from rotary drum one end with slide unit; Perpendicular to the toggle of rotary drum axle horizontally set, the one end is fixed on the housing of oil motor, and the other end is connected with the lower end of force transducer, and the upper end of force transducer is installed in the stand that is arranged at oil motor one side on the fuselage.
The utility model also has following technical characterictic:
The installation of described force transducer upper and lower side, below described stand, flap seat is installed, suspension rod, force transducer, pull bar are installed downwards below the flap seat successively, its tie point is hinge and connects, the lower end of pull bar is fixed with hanger, leaving between oil motor one end of hanger and toggle flexibly connects with bearing pin;
Be positioned at a side of hanger on the column of described stand, be provided with bearing above toggle, stop screw was twisted the bolt hole on the bearing downwards, the upper edge of subtend toggle.
When being installed in tire on the wheel rim and carrying out the resistance to rolling test, start the hydraulic cylinder of fuselage, slide unit push boat tire is pressed to simulated roadway face on the rotary drum by the load of setting, primer fluid pressure motor band rotary drum rotates, the reacting force of the tyre rotation of bearing on the oil motor, pass to force transducer by the toggle that is fixed on the oil motor housing, thereby finish the resistance to rolling test of tire.
Advantage of the present utility model and good effect be, owing between hydraulic motor output shaft and the rotary drum axle, directly connect without torque sensor, do not exist because of unnecessary use and damage problem easily.Owing to be connected with force transducer with the fixedly connected toggle of oil motor housing, like this, the friction force that oil motor overcomes between tire and rotary drum drives the rotary drum revolution, and required torque value is directly detected by force transducer, force transducer degree of accuracy height, test data is reliable; Said apparatus is simple in structure, uses maintenance very convenient.
