Description

Technical Field

[0001] This utility model relates to the field of rocker arm technology, specifically an impact-resistant motorcycle rocker arm. Background Technology

[0002] Currently, the swingarm is a crucial component of a motorcycle, connecting the frame and rear shock absorber. It transmits and bears the forces and torques between the two, making it an indispensable part of the vehicle's suspension system. A stable swingarm is essential for improving handling.

[0003] According to a motorcycle rocker arm disclosed in the public notice (Announcement No.: CN213229029U), when lubricating oil needs to be added, the elastic seal is removed from the fixed tube, and then lubricating oil is added into the operating hole. The lubricating oil passes through the operating hole and the insertion hole and enters the gap. After the lubricating oil is added, the operating hole is resealed with the elastic seal.

[0004] However, in actual use, although the above-mentioned equipment can add lubricating oil to the fixed tube, the fixed tube will vibrate after being impacted, causing the internal lubricating oil to flow out, resulting in instability during use; in view of this, we propose an impact-resistant motorcycle rocker arm. Utility Model Content

[0005] The purpose of this invention is to provide an impact-resistant motorcycle rocker arm to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an impact-resistant motorcycle rocker arm, comprising a support rod, a fixing rod provided on the outer wall of the support rod, a fixing tube fixedly connected to the end of the fixing rod, an impact-resistant component provided on the outer wall of the fixing tube to reduce impact when subjected to impact, the impact-resistant component comprising an extension plate, the extension plate fixedly connected to the outer wall of the fixing tube, a fixing bolt threadedly connected to the inner wall of the extension plate, a fixing nut threadedly connected to the outer wall of the fixing bolt, an installation plate detachably mounted on the outer wall of the fixing bolt, and an elastic telescopic plate fixedly connected to the outer wall of the installation plate; A connecting side plate is fixedly connected to the end of the elastic telescopic plate. An impact-resistant rubber pad is fixedly connected to the end of the connecting side plate. A protruding rubber block is fixedly connected to the outer wall of the impact-resistant rubber pad. An extension seat is fixedly connected to the outer wall of the mounting plate. A buffer rubber head is fixedly connected to the end of the extension seat.

[0007] Preferably, the center line of the extension seat and the center line of the buffer rubber head are on the same straight line.

[0008] Preferably, the impact-resistant rubber pad is slidably connected to the outer wall of the fixed tube, and the inner wall of the impact-resistant rubber pad is adapted to the outer wall of the fixed tube.

[0009] Preferably, the extension plates are provided in two sets, and the two sets of extension plates are arranged on both sides mirroring the center plane of the support rod.

[0010] Preferably, the outer wall of the mounting plate is provided with a positioning component for limiting the fixing bolts. The positioning component includes a turntable, which is rotatably mounted on the outer wall of the mounting plate. A spring-loaded telescopic rod is fixedly connected to the outer wall of the turntable. A movable plate is fixedly connected to the end of the spring-loaded telescopic rod. A limit head is fixedly connected to the outer wall of the movable plate.

[0011] Preferably, the centerline of the elastic telescopic rod and the centerline of the turntable are on the same straight line.

[0012] Preferably, the outer wall of the limiting head is adapted to the inner wall of the fixing bolt, so that the limiting head can be smoothly inserted into the inner wall of the fixing bolt.

[0013] Compared with the prior art, this utility model provides an impact-resistant motorcycle rocker arm, which has the following beneficial effects: 1. This impact-resistant motorcycle rocker arm allows for convenient application of lubricant to the fixed tube during daily use. During installation, the fixed tube can be quickly installed. Before installation, the mounting plate can be attached to the extension plate using fixing bolts. Simultaneously, the impact-resistant rubber pad is fitted onto the outer opening of the fixed tube. This allows the fixed tube to be cushioned by the impact-resistant rubber pad and the raised rubber block when subjected to external impacts, ensuring the normal operation of the motorcycle rocker arm. Furthermore, the extension seat and buffer rubber head allow for secondary cushioning of the impact-resistant rubber pad after displacement, further enhancing the overall stability and practicality.

[0014] 2. This impact-resistant motorcycle rocker arm, after the mounting plate is installed on the extension plate by fixing bolts, can pull the elastic telescopic rod and rotate the turntable, so that when the limit head on the moving plate moves to the fixing bolt, the stretched elastic telescopic rod can be released, so that the moving plate and the limit head can be engaged in the fixing bolt after displacement, ensuring that the fixing bolt will not be twisted due to accidental contact in subsequent operations, and that the fixing bolt can maintain good stability.

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: an impact-resistant motorcycle rocker arm, including a support rod 1, a fixing rod 2 provided on the outer wall of the support rod 1, a fixing tube 3 fixedly connected to the end of the fixing rod 2, an impact-resistant component 4 for reducing impact when subjected to impact provided on the outer wall of the fixing tube 3, the impact-resistant component 4 including an extension plate 401, the extension plate 401 fixedly connected to the outer wall of the fixing tube 3, a fixing bolt 402 threadedly connected to the inner wall of the extension plate 401, a fixing nut 403 threadedly connected to the outer wall of the fixing bolt 402, an installation plate 404 detachably installed on the outer wall of the fixing bolt 402, and an elastic telescopic plate 405 fixedly connected to the outer wall of the installation plate 404.

[0018] Furthermore, the connecting side plate 406 is fixedly connected to the end of the elastic telescopic plate 405, and an impact-resistant rubber pad 407 is fixedly connected to the end of the connecting side plate 406. A protruding rubber block 408 is fixedly connected to the outer wall of the impact-resistant rubber pad 407. An extension seat 409 is fixedly connected to the outer wall of the mounting plate 404, and a buffer rubber head 410 is fixedly connected to the end of the extension seat 409.

[0019] In the embodiments of this utility model, the center line of the extension seat 409 and the center line of the buffer rubber head 410 are on the same straight line. The impact-resistant rubber pad 407 is slidably connected to the outer wall of the fixed tube 3, and the inner wall of the impact-resistant rubber pad 407 is adapted to the outer wall of the fixed tube 3. The extension plate 401 is provided in two sets, and the two sets of extension plates 401 are mirrored on both sides with the center plane of the support rod 1.

[0020] The outer wall of the mounting plate 404 is provided with a positioning component 5 for limiting the fixing bolt 402. The positioning component 5 includes a turntable 501, which is rotatably mounted on the outer wall of the mounting plate 404. A spring telescopic rod 502 is fixedly connected to the outer wall of the turntable 501. A movable plate 503 is fixedly connected to the end of the spring telescopic rod 502. A limiting head 504 is fixedly connected to the outer wall of the movable plate 503. The center line of the spring telescopic rod 502 and the center line of the turntable 501 are on the same straight line. The outer wall of the limiting head 504 is adapted to the inner wall of the fixing bolt 402, so that the limiting head 504 can be smoothly inserted into the inner wall of the fixing bolt 402.

[0021] In this utility model, lubricating oil can be conveniently applied to the fixed tube 3 during daily use, and the fixed tube 3 can be quickly installed during installation. Before installing the fixed tube 3, the mounting plate 404 can be installed on the extension plate 401 using the fixing bolt 402. At the same time, the impact-resistant rubber pad 407 is fitted onto the outer opening of the fixed tube 3, so that when the fixed tube 3 is subjected to external impact, the impact-resistant rubber pad 407 and the convex rubber block 408 can buffer the impact, ensuring the normal operation of the motorcycle rocker arm. Furthermore, the extension seat 409 and the buffer rubber head 410 can provide secondary buffering for the impact-resistant rubber pad 407 after displacement, further improving the overall stability and practicality.

[0022] After the mounting plate 404 is installed on the extension plate 401 by fixing bolt 402, the elastic telescopic rod 502 can be pulled and the turntable 501 can be rotated. This allows the limiting head 504 on the moving plate 503 to relax the stretched elastic telescopic rod 502 when it is moved to the fixing bolt 402. As a result, after the moving plate 503 and the limiting head 504 are moved, the limiting head 504 can be engaged in the fixing bolt 402. This ensures that the fixing bolt 402 will not twist due to accidental contact in subsequent operations, and that the fixing bolt 402 can maintain good stability.
