Abstract
Description
Technical Field
[0001] The utility model relates to the field of motorcycle detection equipment, in particular to a motorcycle front and rear wheel alignment detection device. Background Art
[0002] Two-wheeled motor vehicles are currently the most commonly used means of transportation, especially in congested cities, where they are increasingly used due to their convenience.
[0003] Currently, motorcycles are tested for centering of the front and rear wheels before leaving the factory or during maintenance to ensure the stability of the motorcycle. However, the existing front and rear wheel alignment is usually only judged by the experience of workers, and there are no special tools for front and rear wheel alignment detection, which makes the front and rear wheel alignment detection have a certain possibility of error. Utility Model Content
[0004] The utility model aims to provide a motorcycle front and rear wheel centering detection device which can increase the accuracy of the motorcycle front and rear wheel centering.
[0005] In order to solve the above technical problems, the utility model provides a motorcycle front and rear wheel centering detection device, including a frame, and at least two centering detection mechanisms symmetrically arranged on the inner side of the frame, the centering detection mechanism includes a movably arranged main board and a sub-board rotatably arranged on both sides of the main board, when the motorcycle is in the detection position, the sub-board is placed on the side of the front wheel or the rear wheel.
[0006] Furthermore, a main telescopic rod is connected between the main board and the frame, a secondary telescopic rod is connected between the secondary board and the frame, and an elastic part is built into the secondary telescopic rod. When the main telescopic rod is extended or retracted, the secondary telescopic rod is extended or retracted synchronously.
[0007] Furthermore, the end of the secondary telescopic rod facing the secondary plate is provided with a laser element, and a plurality of detection strips are arranged at intervals along the horizontal direction on the inner side of the secondary plate, and the plurality of detection strips are correspondingly matched with the laser element.
[0008] Furthermore, a limiting plate is provided on one side of the auxiliary plate, and a rotating shaft is rotatably installed between the limiting plate and the auxiliary telescopic rod.
[0009] Furthermore, an observation window is provided on the top of the sub-plate, and the observation window corresponds to a plurality of detection strips.
[0010] Furthermore, depressions are provided on both sides of the frame, and the front wheels and the rear wheels enter the inner side of the frame from the depressions.
[0011] Furthermore, an indicator line is provided at the middle position of the depression.
[0012] The beneficial effect of the utility model lies in that the two centering detection mechanisms on the inner side are stabilized by the frame. When the motorcycle needs to perform front and rear wheel centering detection, the motorcycle is placed on the inner side of the frame and between the two centering detection mechanisms. Then the main board is moved toward the position of the motorcycle. At this time, the main board drives the sub-board to move synchronously, so that the sub-board clamps and detects the sides of the front and rear wheels. During the clamping detection process, if the front and rear wheel centering detection is normal, that is, the sub-board will not rotate relative to the main board, and if the front and rear wheels are unbalanced in centering, that is, the front or rear wheel is skewed or offset, the sub-board at this location is blocked by the tire, so that the sub-board will tilt and rotate to one side during the movement of the main board, so that the staff can easily and intuitively see the imbalance in centering of the front and rear wheels.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.
[0018] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.
[0019] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.
[0020] like Figure 1-3 The utility model provides a motorcycle front and rear wheel centering detection device, comprising a frame 1, and at least two centering detection mechanisms symmetrically arranged on the inner side of the frame 1. The centering detection mechanism comprises a movably arranged main board 2, and a sub-board 3 rotatably arranged on both sides of the main board 2. When the motorcycle is in the detection position, the sub-board 3 is placed on the side of the front wheel or the rear wheel.
[0021] The two centering detection mechanisms on the inner side are stabilized by the frame. When the motorcycle needs to be tested for front and rear wheel centering, the motorcycle is placed on the inner side of the frame and between the two centering detection mechanisms. The main board is then moved toward the position of the motorcycle. At this time, the main board drives the sub-board to move synchronously, so that the sub-board clamps and detects the sides of the front and rear wheels. During the clamping detection process, if the front and rear wheel centering detection is normal, that is, the sub-board will not rotate relative to the main board, and if there is an imbalance in the centering of the front and rear wheels, that is, the front or rear wheel is skewed or offset, the sub-board at this location will be blocked by the tire, so that the sub-board will tilt and rotate to one side during the movement of the main board, so that the staff can easily and intuitively see the imbalance in the centering of the front and rear wheels.
[0022] It is worth mentioning that the main boards in the two pairs of detection mechanisms are parallel to each other, and when the front and rear wheels are not detected, the sub-boards in the two pairs of detection mechanisms are parallel to each other.
[0023] Preferably, a main telescopic rod 4 is connected between the main board 2 and the frame 1, a secondary telescopic rod 5 is connected between the secondary board 3 and the frame 1, and the secondary telescopic rod 5 has an elastic member built therein, and when the main telescopic rod 4 is telescoped, the secondary telescopic rod 5 is telescoped synchronously.
[0024] Specifically, when the main board moves toward the position of the motorcycle, the main board is driven to move by the extension of the main telescopic rod. At the same time, since the secondary telescopic rod has an elastic member inside, the elastic member pushes the secondary telescopic rod to move synchronously. When the front and rear wheels are unbalanced in alignment, the secondary board is blocked by the tire, so that the elastic member cannot continue to push the secondary telescopic rod to extend, and then the secondary board rotates relative to the main board when the main board continues to move.
[0025] Wherein, the elastic member adopts a spring structure.
[0026] Preferably, the end of the secondary telescopic rod 5 facing the secondary plate 3 has a laser element 6 , and a plurality of detection strips 7 are arranged at intervals along the horizontal direction on the inner side of the secondary plate 3 , and the plurality of detection strips 7 correspond to the laser element 6 .
[0027] Specifically, the laser element emits a laser toward the position of the detection strip. When the sub-board is blocked by the front wheel and tilted, the position of the laser emitted by the laser element will also be shifted accordingly, so that the staff can easily observe whether the front and rear wheels are skewed through the position of the laser irradiation.
[0028] The laser element may be a level instrument or the like.
[0029] In particular, the interval between two adjacent detection strips can be adjusted at the factory or during design, so that the detection strips can more accurately display the front and rear wheel offset conditions.
[0030] Preferably, a limiting plate 8 is provided on one side of the auxiliary plate 3 , and a rotating shaft 9 is rotatably installed between the limiting plate 8 and the auxiliary telescopic rod 5 .
[0031] Specifically, by cooperating with the limit plate and the rotating shaft, when the sub-plate is tilted, it can rotate relative to the sub-telescopic rod. Since the sub-telescopic rod itself will not rotate accordingly, the irradiation position of the laser element will change when the sub-plate is tilted, thereby improving the convenience of detection.
[0032] Preferably, an observation window 10 is provided on the top of the sub-plate 3 , and the observation window 10 corresponds to the plurality of detection strips 7 .
[0033] Specifically, since the detection strip is located on the inner side of the sub-plate, an observation window is provided to facilitate observation by the staff, so that the staff can conveniently observe the laser irradiation position from the observation window.
[0034] Preferably, recesses 11 are provided on both sides of the frame 1 , and the front wheels and the rear wheels enter the inner side of the frame 1 through the recesses 11 .
[0035] Specifically, when the motorcycle enters the inner side of the frame and waits for centering detection, the motorcycle can enter the frame through the recessed position, making the process of the motorcycle entering the frame easier.
[0036] Preferably, an indicator line 12 is provided in the middle of the recess 11 .
[0037] Specifically, the entry position and parking position of the motorcycle can be indicated by the indicator line to facilitate the accuracy of subsequent centering detection.
[0038] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
