Abstract
The invention provides a device for detecting dynamic balance and uniformity of motor vehicle tyres. The structure is as follows: the head end of a central axle is provided with a circular tyre chuck plate used for clamping the tyre to be detected; a synchronous driver is assembled in the middle of the central axle and is driven by a variable frequency motor to rotate; a support is installed at a position closing to the circular tyre chuck plate; vibration sensors are symmetrically installed around the central axle on the support; and the detection signals of the vibration sensor is transmitted to an external industrial personal computer. The invention can not only detect the uniformity of motor vehicle tyres, but also can detect dynamic balance of the tyre; the invention has simple structure, low cost, convenient installation and use, light weight, easy dismounting and transmission; and the detection with high precision can be finished in a short time.
Description
Technical field
The present invention is used for a kind of machines motor-car tire dynamic and balance and inhomogeneity equipment, is particularly useful for a kind of machines motor-car air leak preventing tyre transient equilibrium and inhomogeneity equipment.
Background technology
Motor vehicle is in the process of travelling, especially running at high speed, if owing to tire motion state imbalance, particularly the front-wheel imbalance is very easily caused danger.Gently then vehicle shake, it is undesired to travel; Heavy then may cause sideslip, out of hand, even the pernicious traffic hazard that vehicle is overturned takes place, not only life danger easily takes place in driver and occupant, and entail dangers to is to the safety of other vehicles, personnel and society, thereby the country and people's lives and properties are caused quite serious harm and loss.Therefore, the dynamic equilibrium problems of tire is the minor issue that can not ignore, and it is related to the safety of people's life and property.
The existing in the market device that is used for the measuring wheel tyre uniformity, this device is only measured the homogeneity of testing tire; Also be useful on simultaneously the device of measuring tire dynamic and balance, the transient equilibrium that this device is only measured testing tire.Dynamic balance measuring device is the degree of eccentricity that detects this testing tire according to the vibrational state during its rotation.Therefore, its structure of this dynamic balance measuring device will be used to support rotatable testing tire, meanwhile, can allow it during turning to vibrate.But because in the difference that exists aspect the supporting testing tire; So, be difficult to adopt an independent general measurement mechanism not only to measure the homogeneity of testing tire but also measure its transient equilibrium always.For a long time, a kind of isolated system simple in structure is adopted in expectation always, and it is the homogeneity of energy measurement wheel tyre both, also the dynamic balance of energy measurement wheel tyre.
Summary of the invention
At the monistic defective of present above-mentioned checkout equipment, the purpose of this invention is to provide a kind of pick-up unit, adopt this independent device can carry out the homogeneity and/or the dynamically balanced measurement of wheel tyre, this device especially can detect the homogeneity and/or the transient equilibrium of air leak preventing tyre.
The present invention constitutes like this: a kind of tire dynamic and balance and homogeneity pick-up unit comprise tire chuck, shock sensor, synchronous driver, axis, plane electro-magnetic braking device, variable-frequency motor, bearing, industrial computer.
Tyre detection device of the present invention, the homogeneity that can not only detect automobile tyre also can detect the transient equilibrium of tire simultaneously, and it can detect the ordinary motor vehicle tire, is particularly useful for detecting air leak preventing tyre.The present invention is simple in structure, and is cheap, and it is extremely convenient to install and use, and in light weightly is easy to dismounting transportation, and the short time can be finished detection, and precision is higher.
Description of drawings
Fig. 1 is tyre evenness of the present invention and dynamic balance detecting device structural representation sketch.
Among the figure: 1 tire chuck, 2 shock sensors, 3 synchronous driver, 4 axis, 5 plane electro-magnetic braking devices, 6 variable-frequency motors, 7 bearings.
Embodiment
Referring to Fig. 1, structure of the present invention is: be equipped with the tire chuck 1 of a circle at the head end of axis 4, being used to clamp needs the tire that detects.Tire chuck 1 is many specifications formula, can adjust its diameter to adapt to the tire of all size.Synchronous driver 3 of assembling in the middle of the axis 4, synchronous driver 3 is by variable-frequency motor 6 driven rotary.Between synchronous driver 3 and circular tire chuck 1, near circular tire chuck 1 place bearing 7 is installed, axis 4 passes through from bearing 7.On bearing 7, be equipped with 4-10 shock sensor 2 symmetrically around axis 4, generally speaking, use 8 shock sensors 2 to detect.The detection signal of shock sensor 2 is transferred to outside industrial computer (not shown) by data line.At the tail end of axis 4, a plane electro-magnetic braking device 5 is installed, in order to axis 4 brakings to rotation.
The principle of work of the present invention and the course of work are: with automobile tyre, need not to install under the condition of wheel rim, utilizing the many specifications tire chuck 1 that is installed on the axis 4 to be fixedly clamped.Drive synchronous driver 3 by variable-frequency motor 6, thereby drive axis 4 rotations.Rotational speed can be decided to be the travel speed of simulation tire on the road surface.Utilization is installed in the shock sensor 2 of axis 4 symmetrical surface, the shock value that produces because of unbalance dynamic after the rotation is transferred to industrial computer by data line carries out interpretation calculating, after the unbalance dynamic calculated value is determined, control of conversion motor 6 slows down the output speed step, after determining unbalance dynamic point, when speed drops to setting value, be installed in plane electro-magnetic braking device 5 work of axis 4 tail ends.Finish measure numerical value after, industrial computer instruction variable-frequency motor 6 rotates to specified angle with tire chuck 1, plane electro-magnetic braking device 5 is with axis 4 lockings, promptly tire chuck 1 is locked, with uneven point location at set angle, so that begin to revise operation.
Adopt the measurement mechanism of said structure, with regard to measuring transient equilibrium, clamping will be tested the spindle unit of tire, can vibrate during it rotates; Yet, when carrying out uniformity measurement, during its rotation, to prevent the heart shaft part vibration; So just can utilize an independent device not only to measure the transient equilibrium of wheel tyre but also measure its homogeneity.
