Description
Technical field
The utility model relates to a kind of portable automobile wheel steering angle tester.
Background technology
Steer angle refers to that wheel is when turning to, the angle between the center line of the center line of tire and wheel tire when in-line position.During wheel steering, first road surface can produce additional resistance to automobile, secondly when left and right wheel turns to identical corner, its radius of turn is also identical, this just causes each wheel to rotate around different turning centers, generation is breakked away by wheel, and tire will have abnormal wearing and tearing.
In order to avoid the irregular wear of wheel tyre, when turning to, left and right two wheels do pure rolling and are just inevitable, and at this moment require all to turn to around a turning center during all wheel steerings.The steering angle of left and right wheel would not be equal, from design get on the car left and right wheel turning angle meet the theory relation of Ackermann angle time, all wheels will do without break away pure rolling.
Utility model content
The purpose of this utility model is to provide a kind of portable automobile wheel steering angle tester, can measure the steering angle of the left and right wheel of automobile to be measured.
For solving the problems of the technologies described above, the utility model provides a kind of portable automobile wheel steering angle tester, comprises clamp assemblies, and clamp assemblies comprises two holders.The toothed gearing that steer angle tester is also comprised microcontroller, base and is connected with clamp assemblies by connecting rod; Toothed gearing comprises the driven wheel be fixed on by driving wheel on base, and is fixed on the follower gear on base by engaged wheel; Driven wheel is meshed with follower gear; Follower gear is provided with the scrambler with its coaxial rotation; Scrambler is connected to microprocessor, and microprocessor is connected with display panel.
Further, driven wheel comprises disc parts and outward extending two pitman arms of diametric(al) along disc parts; Two pitman arms are connected with a clamp assemblies respectively by a connecting rod; Disc parts is provided with the circular hole coordinated with driving wheel.
Further, driven wheel is only shaped with teeth portion in the outer rim of the disc parts of the side of engaging with follower gear.
Further, the card away from follower gear side of disc parts is provided with chute; The conduit be bolted on base is provided with in chute.
Further, base is also provided with follower gear covered on wherein in inverted U-shaped support, the top of support is provided with the spacing hole for firm scrambler.
Further, the bottom surface of base is provided with multiple feet.
The beneficial effects of the utility model are:
Be clamped on wheel tyre by clamp assemblies when 1, using, because clamp assemblies is connected with driven wheel by connecting rod, so when wheel tyre rotates, clamp assemblies will drive driven wheel to rotate, and drive engaged wheel to rotate further.Due to scrambler and engaged wheel coaxial rotating, the angle that follower gear rotates is transferred to microprocessor by scrambler as electronic signals, microprocessor goes out the anglec of rotation of wheel according to the gear ratio calculation of driven wheel and follower gear, and by the display of the anglec of rotation of wheel on a display panel.Adopt the steer angle tester of this kind of structure, highly sensitive, the steering angle of the left and right wheel of automobile to be measured can be measured.
2, the utility model can install this tester respectively simultaneously on the left and right wheel of automobile, can survey the steering angle of two wheels simultaneously, and demonstrate the difference of the steering angle of left and right wheel.
3, the utility model structure is simple, is easy to carry.
