Description
Technical field
A kind of toe-in of automobile measuring method the present invention relates to toe-in of automobile measuring device and using the device.
Background technology
Automobile chassis needs to be adjusted toe-in, and after automobilism for a period of time, it is overproof to easily cause Wheel toe-in, from
And phenomena such as causing running out the way, at a high speed pendulum shake, waving at high speed, abnormal tyre abrasion.At present, in the maintenance of steering axle of automobile
Cheng Zhong, many producers all adjust toe-in using the four-wheel positioning measurement equipment of specialty, but the kind equipment not only invest it is big but also
It is cumbersome, fail to obtain popularization and effectively application in regional service station and maintenance station.
To solve the above-mentioned problems, in the prior art frequently with easy prenex survey tool, as shown in Figure 1, prenex survey
Amount instrument includes left socle 80 and right support 81, and cross bar 82 is equipped between left and right stent, and left and right stent can be along the axis of cross bar 82
To guiding movement, and then the distance between two stands are adjusted, there is measurement head on two stands, the tire of measurement head and tire during measurement
Hat positioning contact, has scale on cross bar 82, it is measurable go out the distance between two stands.During measurement, by automobile parking in platform
On, positive vehicle steering is beaten, that is, it is in straight-going state to adjust automotive wheel 83, and a fixed point, two fixed points point are respectively taken on left and right wheel
It left Wei not measure fixed point and right measurement pinpoints, the left and right fixed point that measures is horizontal with the line at corresponding hub for vehicle wheel center,
Prenex survey tool is corresponding with measurement fixed point, as shown in Fig. 2, the distance between left and right measurement fixed point of measurement, measurement data is
A, rotates automotive wheel, turns a wheel 180 °, measures the distance between left and right measurement fixed point again, measures second group of number
According to B, it is known that a diameter of D of automotive wheel, calculates the difference B-A of A and B, which is toe-in value, according to the diameter of automobile
D can also calculate preceding beam tilt angle.
Above-mentioned toe-in survey tool measures on the inside of wheel, in measurement such as car, lorry, truck oversize vehicle
When, since the distance between left and right wheel is larger, it is necessary to increase the axial length of cross bar so that the length of prenex survey tool
Spend it is larger, during measurement adjustment and positioning be inconvenient, it is longer to be additionally, since the axial length of cross bar, cross bar there are radial missing,
Error during measurement is larger, causes measurement accuracy relatively low.
In the prior art also there are the toe-in value that a kind of toe measurement device of areal survey carrys out automobile, i.e., from automotive wheel
Outside measure, such as the Chinese invention patent application of Application No. 201310413041.9 discloses a kind of joint and receives
Cutting mill detection method for toe-in, and a kind of prenex detection device is disclosed, which uses in pairs, includes symmetrical set per a pair of
