Description
Technical field
The present invention relates to the device measured in the friction factor characteristic on the road surface of running car time contact tire.In more detail, relate to a kind of portable revolving frictionfactor measuring device for road surface that can carry and can directly measure to the friction co-efficient value that can correctly reflect the pavement characteristics that contacts with tire.
Background technology
The friction co-efficient value accurately on actual road surface is the important factors of prediction tyre performance, so the measurement of the friction factor that can correctly reflect pavement characteristics is being played an important role aspect the exploitation tyre performance.
Therefore, people wish to develop a kind of small-sized, portability and can directly carry out the device that friction co-efficient value is measured on the road surfaces of wanting to measure.
Friction factor between actual road surface and the tire by putting on tire pressure (loading) and the function between the sliding speed (slip velocity) that produces under steam represent.In the friction coefficient measuring apparatus that generally uses at present, because test film is made into direction motion forwards, backwards, so test film can't carry out the increase and decrease of speed freely.Therefore, the measurement that consider the sliding speed influence is quite difficult, so can not measure the characteristic on various road surfaces more exactly, is difficult to obtain the required surface friction coefficient accurately of exploitation tyre performance.
Summary of the invention
The present invention proposes in order to solve above-mentioned existing issue, its purpose is, a kind of portable revolving frictionfactor measuring device for road surface is provided, survey crew can carry this device directly in the measurement of the enterprising walking along the street face friction factor in the road surface of reality, can obtain measured value accurately thus.
To achieve the above object, portable revolving frictionfactor measuring device for road surface of the present invention comprises: main part, inside are equipped with working machine and sensor; The test film installation portion is connected with the turning axle of this main part, and rotates with pivot arm, and it has the rubber test sheet; Fulcrum arrangement is bearing in described main part on the road surface, is connected with on the working machine of described main part and sensor and can carries out various data input controls and output input control part and output processing part that handle, that be connected with portable power supply unit.
