Abstract
The invention discloses a device for measuring a dynamic external outline of a tire. The device is characterized by comprising a base plate, a support plate, a guide wheel measurement mechanism, a displacement measurer, a cylinder and a guide wheel, wherein the guide wheel measurement mechanism and the displacement sensor are arranged above the support plate; the cylinder and the guide wheel are arranged below the support plate; the guide wheel measurement mechanism consists of a guide column and a slider which is arranged on the guide rod and can slide left and right; one end of the guide column is fixedly connected with the base plate; the slider is hinged with the guide wheel through the support plate; and the displacement sensor is connected with a signal processor of measurement software. The device can perform measurement during the dynamic experiment of the tire, has the characteristics of simple structure, convenience and practicability and is economic, practical and high in measurement precision.
Description
Technical field
The present invention relates to measurement mechanism, specifically is the dynamic outline measurement mechanism of a kind of tire.
Background technology
In the development and production to tire, the physical dimension of tire is in a relatively-stationary scope, and under static state, we can come the physical dimension of drawings through survey instruments such as steel tapes.But in the actual use of tire, tire is rotating with certain speed.Under the condition of high speed rotating, tire is owing to action of centrifugal force, and the profile of tire has certain expansion, and this expansivity is vital for aircraft tyre wheel limited space, cabin.The measurement mechanism that China is not relevant at present comes drawings in the dynamically variation of physical dimension down, generally all is to calculate according to experimental formula, but along with science and technology development, depends formula to calculating alone and can not satisfy the research and development needs.
Summary of the invention
The objective of the invention is for overcoming the deficiency of prior art, and provide a kind of economical and practical, and the high dynamic outline measurement mechanism of tire of measuring accuracy.
The technical scheme that realizes the object of the invention is:
The dynamic outline measurement mechanism of a kind of tire; By base plate, back up pad, be arranged on guide wheel measuring mechanism and displacement transducer on the back up pad, the signal processor of the Survey Software that is connected with displacement transducer and cylinder and the guide wheel that is arranged under the back up pad form, back up pad links with displacement transducer.
Said guide wheel measuring mechanism by guide pillar be arranged on the slide block that can horizontally slip on the guide pillar and form, guide pillar one end and base plate are affixed, slide block pass through back up pad and guide wheel hinged.
During measurement, after tire reaches measuring speed, rapidly tire and rotary support are broken away from; Utilize cylinder that guide wheel is ejected; Contact rotation with tire, and the distance that guide wheel ejects is sent to displacement transducer, calculate reduction through Survey Software again and obtain tire dynamic profile size.
Advantage of the present invention is: this measurement mechanism can carry out in the tire dynamic test, has simple in structure, convenient and practical characteristics, and economical and practical, and measuring accuracy is high.
Description of drawings
Fig. 1 is the structural representation of the dynamic outline measurement mechanism of tire of the present invention.
Among the figure: 1. base plate 2. slide blocks 3. guide pillars 4. displacement transducers 5. back up pads 6. guide wheels 7. cylinders 8. tires.
Embodiment
Consult Fig. 1; The dynamic outline measurement mechanism of a kind of tire; By base plate 1, back up pad 5, be arranged on slide block 2, guide pillar 3, the displacement transducer 4 on the back up pad 5 and the guide wheel 6 and the cylinder 7 that are arranged under the back up pad 5 are formed, what slide block 2 can horizontally slip is sleeved on the guide pillar 3, and hinged through back up pad 5 and guide wheel; Guide pillar 3 one ends and base plate 1 are welded as a whole, and displacement transducer 4 is connected with the signal processor of Survey Software.
During measurement, under tire 8 static state, utilize cylinder 7 that guide wheel 6 is ejected earlier, measure the distance that tire 8 static lower tumblers 6 eject, this distance is demarcated according to the outside dimension of static state.
According to requirement of experiment, when tire 8 bands being gone to command speed, tire 8 and wheel hub are broken away from rotary support (rotary drum); In the moment that tire 8 and rotary drum break away from; Utilize cylinder 7 that guide wheel 6 is ejected, slide block 2 ejects with guide wheel 6 and on guide pillar 3, slides, and the distance that will slide is sent to the signal processor of Survey Software through displacement transducer 4; Through Survey Software the information of displacement transducer 4 is reduced, can measure tire physical dimension.
