Description
Technical field
The utility model relates to a kind of four-wheel position finder as automobile detection apparatus.
Background technology
Four-wheel position finder is mainly for detection of the mutual alignment between the automotive wheel and orientation angle, comprise camber angle and toe-in angle, to determine vehicle wheel alignment parameter, thereby instruct the auto repair pilot to adjust wheel alignment parameter, to satisfy the Automobile Design requirement, realize ride comfort, the security of running car, reduce automobile fuel consumption and tire wear.
Existing four-wheel position finder mainly is the chuck mode four-wheel position finder.Utilize three claws of chuck to contact with 3 of tire lateral surfaces, these 3 planes that determine are considered to tire plane of living in.Its major defect is: the first, because tire distortion can occur through sidewall face after using, may be in the sags and crests of tire with the contact position of claw, cause 3 planes that determine inaccurate; The second, since only according to 3 of choosing at random as the detection side to reference point, image data quantity is few, does not have the statistical significance of science, what cause finally that wheel alignment parameter detects is inaccurate.
Also having a kind of four-wheel detection and localization mode is optical method, adopts laser probe to detect tire location, obtains testing result by Computer Processing, belongs to contactless four-wheel localization method.The major defect of this method is that the checkout equipment cost is high, and is not suitable for the vehicle testing line of middle and small scale.
The utility model content
Technical problem to be solved in the utility model is, a kind of contacting roller four-wheel position finder is provided, and can gather a large amount of reference datas under the tyre rotation state, thereby obtain accurately four-wheel detection and localization result, to overcome the defective of existing four-wheel position finder.
It is as follows that the utility model solves the problems of the technologies described above the technical scheme that adopts:
The contacting roller four-wheel position finder comprises erecting frame, it is characterized in that: described erecting frame is connected with lower carriage by horizontal rotating shaft, and this lower carriage is equipped with lower roller by web joint; Described lower carriage upper end is connected with horizontal link by vertical rotating shaft, slidely connects respectively the roller installing plate that can lock at the two ends of described horizontal link, on the roller installing plate roller axle is installed, and is connected with roller in described roller axle; One end of described horizontal rotating shaft is connected with lower gear, a side of this lower gear lower induction gear that has been connected with a joggle, and described lower induction gear is connected with lower sensor; Described vertical rotating shaft is connected with cog (10), the described upper induction gear that has been connected with a joggle that cogs, and described upper induction gear is connected with upper sensor.
Also comprise the processor that is connected respectively with described lower sensor and upper sensor.
Also comprise cylinder, described cylinder also is fixedly connected with the trend slideway consistent with cylinder; Described erecting frame is fixedly connected with the slide block that can slide in described slideway; Described erecting frame also is connected with the piston of described cylinder.
Good effect of the present utility model is: when three groups of rollers contact with the tire lateral surface, owing to being provided with take horizontal rotating shaft and the linkwork of vertical rotating shaft as fulcrum, realize unsteady applying between three groups of rollers and the tire lateral surface, can remain good rolling contact.The change amount at the inclination angle of the surface of contact between described roller and the tire is passed through the rotational angle reflection of induction gear, and sends in the processor by sensor, as the basic data of calculating testing result.In addition, the utility model detects under tyre rotation, can obtain to have in a large number the reference data of statistical significance, has guaranteed the accuracy of four-wheel detection and localization data.
