[0023] The principles and features of the present invention are described below in conjunction with all the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] The utility model embodiment discloses a contact-type front wheel aligner detection device.

[0025] Reference Figure 1 A contact front wheel alignment detection device comprises a base 8, on which a frame structure for supporting is fixedly mounted, and the base 8 supports and fixes the position of related equipment. A detection mechanism 1 and a roller mechanism 3 are arranged on the base 8 in order from high to low.

[0026] Reference Figure 1 and Figure 2 The detection mechanism 1 is suitable for detecting the wheel camber angle, wheel toe angle (toe) and other data during the dynamic rolling process of the vehicle's front wheels. The detection mechanism 1 includes at least one positioning wheel 11 and an angle encoder. There are three positioning wheels 11 here. The positioning wheels 11 and the angle encoder are all set in the direction of the roller mechanism 3. The three positioning wheels 11 are all in contact with the front wheel tire. The rotation amount of the positioning wheel 11 is converted into an electrical signal by the angle encoder connected to the lower end of the positioning wheel 11. The system tests and displays the toe angle and camber angle and other data of the tested wheel.

[0027] Reference Figure 1 and Figure 2 A moving cylinder 12 is installed on one side of the detection mechanism 1, and the moving cylinder 12 moves in the horizontal direction. A lifting mechanism 2 is installed below the moving cylinder 12, and the lifting mechanism 2 moves in the vertical direction. The lifting mechanism 2 drives the detection mechanism 1 to move in a direction perpendicular to the moving cylinder 12, and the lifting mechanism 2 is connected to the base 8. The detection mechanism 1 can move freely on the X-axis and the Y-axis through the cooperation of the moving cylinder 12 and the lifting mechanism 2. Further, through the design of the moving cylinder 12 and the lifting mechanism 2, the positioning wheel 11 and the angle encoder can be quickly moved. Through the mutually perpendicular movement relationship, the wheel to be tested can be quickly and efficiently positioned, and the wheel camber angle, wheel toe angle (toe) and other data during the dynamic rolling process of the vehicle front wheel can be further efficiently detected.

[0028] Reference Figure 1 A photoelectric switch is also installed on the detection mechanism 1. Through the setting of the photoelectric switch, the position detection of the vehicle to be detected is realized and the false detection rate is reduced.

[0029] Reference Figure 1 and Figure 2The lifting mechanism 2 can be a cylinder-driven structure. The lifting mechanism 2 here includes a lifting cylinder 21. The lifting cylinder 21 is placed in a vertical state. The lifting cylinder 21 drives the movement direction of the detection mechanism 1 to be perpendicular to the movement direction of the moving cylinder 12, thereby realizing the movement of the detection mechanism 1 in the Y-axis direction, adjusting the height of the detection mechanism 1, and adjusting the position of the detection wheel to ensure that the three detection wheels can have good contact with the most convex surface of the tire side, thereby expanding the types and range of vehicles to be tested to adapt to the detection of tires of different models.

[0030] Reference Figure 1 and Figure 2 The lifting mechanism 2 can also be a common manual drive form, such as a common worm gear and screw handwheel structure. For example, a screw handwheel structure is used, and a locking screw is installed in the screw handwheel. The screw handwheel is used to ensure that the detection mechanism 1 moves in the Y-axis direction, so that the movement direction of the detection mechanism 1 driven by the screw handwheel is perpendicular to the movement direction of the moving cylinder 12. The position of the detection mechanism 1 is adjusted by turning the handwheel. After the position is adjusted, the screw handwheel is locked and fixed by tightening the locking screw. The operation method is to loosen the locking screw on the inside of the screw handwheel, rotate the screw handwheel, adjust the height of the detection mechanism 1, and adjust the positions of the three positioning wheels 11 to ensure that the three positioning wheels 11 can have good contact with the most convex surface of the tire side. After the adjustment is completed, tighten the locking screw on the inside of the screw handwheel.

[0031] Reference Figure 1 and Figure 2 The roller mechanism 3 includes a motorized roller 31, a driven roller 32 and at least one brake device, and the brake devices are connected to the motorized roller 31 and the driven roller 32. Under the friction of the roller surface, the tire rotates with the motorized roller 31 and the driven roller 32. The brake mechanism is used to hold the motorized roller 31 and the driven roller 32 tightly, so as to facilitate the vehicle to enter and exit.

[0032] Reference Figure 1 A floating mechanism 4 is installed below the roller mechanism 3. The floating mechanism 4 plays a shock-absorbing role. The floating mechanism 4 is connected to the base 8 and is placed between the roller mechanism 3 and the base 8, which greatly reduces the vibration force generated by the wheel during the test, further protects the detection equipment, and improves the overall service life of the equipment.

[0033] Reference Figure 1 and Figure 2A wheel-track moving mechanism 7 is arranged below the floating mechanism 4. The wheel-track moving mechanism 7 is a pulley structure that moves in position, drives the floating mechanism 4 to move, and further drives the base 8, the detection mechanism 1 and the rolling mechanism to move. The moving direction of the wheel-track moving mechanism 7 is consistent with the moving direction of the moving cylinder 12. By adjusting the wheel-track moving mechanism 7, various parameter detections can be performed on the wheels of vehicles of different types and sizes. At the same time, the floating mechanism 4 is used to support the roller mechanism 3, achieve a high degree of freedom, and release the stress of the tire.

[0034] Reference Figure 1 A centering mechanism 5 and a rear wheel alignment mechanism 6 are placed on one side of the base 8, and the rear wheel alignment mechanism 6 and the centering mechanism 5 are both located on the same side of the base 8. The arrangement of the rear wheel alignment mechanism 6 and the centering mechanism 5 facilitates the operator to calibrate and center the rear wheels of the vehicle to be tested, thereby simplifying the process steps of the operator's test operation.

[0035] The implementation principle of the contact-type front wheel alignment detection device of the utility model embodiment is as follows:

[0036] Drive the wheels of the waiting vehicle onto the roller mechanism 3, adjust the height of the detection mechanism 1 through the movement adjustment of the mobile cylinder 12 and the lifting mechanism 2, adjust the positions of the three positioning wheels 11, ensure that the three positioning wheels 11 can all have good contact with the most convex surface of the tire side, make the three positioning wheels 11 contact with the front wheel tire, and the rotation amount of the positioning wheel 11 is converted into an electrical signal by the angle encoder connected to the lower end of the positioning wheel 11, and the system tests and displays the data such as the toe angle and camber angle of the tested wheel.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
