Description

Technical fields:

[0001] This utility model relates to an auxiliary wheel for off-road motorcycles, belonging to the field of motorcycle technology. Background technology:

[0002] As people's living standards improve, when choosing their mode of transportation, many young people prefer motorcycles to four-wheeled cars because they are more flexible and convenient. However, due to their special two-wheeled design, motorcycles are more difficult to balance and require riders to have certain riding experience and good balance. Beginners do not have these advantages, so people choose to use training wheels to assist in riding.

[0003] The existing motorcycle training wheels have an unreasonable structural design, are cumbersome to install, and are not convenient to use. They cannot adjust the width and height according to different motorcycle models, thus failing to meet people's needs. Therefore, there is an urgent need for a motorcycle training wheel that is easy to adjust. Utility model content:

[0004] To address the above problems, the technical problem to be solved by this utility model is to provide an auxiliary wheel for off-road motorcycles.

[0005] This utility model discloses an auxiliary wheel for off-road motorcycles, comprising a left auxiliary wheel, a right auxiliary wheel, a first wheel rod, a second wheel rod, a rotating adjustment sleeve, a positioning seat, a washer, a screw, and an adjusting crossbar. The left and right auxiliary wheels are respectively fixed to one end of the first and second wheel rods by nuts. The other end of the first and second wheel rods is welded with a rotating adjustment sleeve. The rotating adjustment sleeve has a toothed column hole. The two rotating adjustment sleeves are respectively sleeved on the toothed column bodies of the two positioning seats through the toothed column holes, and are fixed to the central positioning hole of the toothed column body through the washer and the screw. The outer toothed ring on the toothed column body meshes with the inner toothed ring in the toothed column hole of the rotating adjustment sleeve.

[0006] Both positioning seats have threaded rods on their inner sides, with nuts screwed onto the threaded rods. The two positioning seats are assembled at the left and right ends of the adjusting column via the threaded rods and are screwed into the internal threaded holes inside the adjusting column, and are fixed by nuts.

[0007] Preferably, wheel rod one and wheel rod two adopt an arc-shaped structure design, and the height of the left and right auxiliary wheels off the ground can be adjusted by rotating the rotating adjustment sleeve.

[0008] Preferably, the threads on the threaded rods of the two positioning seats are designed with opposite directions, while the internal thread of the adjusting crossbar is designed with one direction. The purpose of adjusting the mounting hole distance of the positioning seats is achieved by adjusting the crossbar.

[0009] Preferably, each of the two positioning seats has a positioning hole on its upper part, and the two positioning seats are fixed on the left and right pedal support frames of the motorcycle frame and secured by screws and nuts.

[0010] The beneficial effects of this utility model are: it has a reasonable structural design, is easy to install and use. Through improvements, it can not only adjust the width to match motorcycles with different frame widths on the market, but also adjust the height to match motorcycles with different heights. The height of the motorcycle changes with the modification of the wheels, thus meeting people's usage needs. Attached image description:

Detailed implementation method:

[0018] like Figures 1-5 As shown, this specific embodiment adopts the following technical solution: It includes a left auxiliary wheel 1, a right auxiliary wheel 2, a wheel rod 1 3, a wheel rod 2 4, a rotary adjustment sleeve 5, a positioning seat 6, a washer 7, a screw 8, and an adjustment cross column 9. The left auxiliary wheel 1 and the right auxiliary wheel 2 are respectively fixed to one end of the wheel rod 1 3 and the wheel rod 2 4 by nuts. The other end of the wheel rod 1 3 and the wheel rod 2 4 are both welded with rotary adjustment sleeves 5. The rotary adjustment sleeves 5 are provided with toothed column holes 501. The two rotary adjustment sleeves 5 are respectively sleeved on the toothed column bodies 601 of the two positioning seats 6 through the toothed column holes 501, and are fixed to the center positioning hole of the toothed column body 601 through the washer 7 and the screw 8. The outer toothed ring on the toothed column body 601 meshes with the inner toothed ring of the toothed column hole 501 in the rotary adjustment sleeve 5.

[0019] Both positioning seats 6 have threaded rods 602 on their inner sides, and nuts 603 are screwed onto the threaded rods 602. The two positioning seats 6 are assembled at the left and right ends of the adjusting column 9 through the threaded rods 602 and screwed into the internal threaded holes in the adjusting column 9. After adjusting the installation width distance, they are fixed by nuts 603.

[0020] The rotating adjustment sleeve 5 is fixedly connected to wheel rod 3 and wheel rod 4 by welding. Wheel rod 3 and wheel rod 4 adopt an arc-shaped structure design. By opening the screw 8, the rotating adjustment sleeve 5 is separated from the toothed column 601. By rotating wheel rod 3 and wheel rod 4, the direction of the arc of wheel rod 3 and wheel rod 4 is changed to adjust the ground clearance of the auxiliary wheel. It is suitable for motorcycles with different wheel heights and frames. After adjustment, the rotating adjustment sleeve 5 is connected to the toothed column 601 and fixed by the meshing of the teeth on the locking screw 8.

[0021] The threads on the threaded rods 602 on the two positioning seats 6 are designed with opposite directions, while the internal thread of the adjusting column 9 is designed with one direction. By rotating the adjusting column 9 in both forward and reverse directions, the adjusting column 9 drives the threaded rods 602 to move inward or outward to adjust the installation width of the auxiliary wheel. After adjustment, the nut 603 is rotated to fix it to the adjusting column 9 to achieve a locking effect. At this time, it cannot be adjusted. Loosening the nut 603 and rotating the adjusting column 9 will adjust the width.

[0022] Positioning holes 604 are provided on the top of the two positioning seats 6. The two positioning seats 6 are fixed on the left and right pedal support frames of the motorcycle frame and are fixed by screws and nuts.

[0023] The working principle of this specific embodiment is as follows: Loosen the screw 8, rotate the adjusting sleeve 5 to disengage from the toothed column 601, and after rotating to the appropriate direction, the adjusting sleeve 5 connects with the toothed column 601. The toothed column hole 501 inside the adjusting sleeve 5 meshes with the external thread of the toothed column 601 and is fixed by the screw 8. The adjustment and fixing method of the internal and external teeth allows for more adjustment levels, and at the same time, the two teeth mesh more firmly.

[0024] This specific implementation method has a reasonable structural design, is simple to install, and is easy to use. Through improvements, it can not only adjust the width to match motorcycles with different frame widths on the market, but also adjust the height to match motorcycles with different heights. The height of the motorcycle changes with the modification of the wheels, thus meeting people's usage needs.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
