Technical Field

[0001] The utility model belongs to the technical field of motorcycle rocker arms, in particular to a motorcycle rocker arm with adjustable travel. Background Art

[0002] A motorcycle swingarm with adjustable travel usually refers to a swingarm designed with an adjustable connection point or structure, which allows the owner or technician to adjust the length or angle of the swingarm according to actual needs, thereby changing the travel of the rear wheel and the characteristics of the suspension system.

[0003] In the prior art, as one of the key components of a motorcycle, the motorcycle rocker arm has a relatively simple handle stroke adjustment function, which is often achieved by relying on a fixed connection method or a simple spring force. Since the motorcycle will inevitably vibrate during driving, although some motorcycle rockers use adjustable nuts to adjust the stroke, in the absence of effective locking measures, the nut is prone to self-rotation due to vibration, causing the adjusted stroke to change, thereby reducing the control safety and comfort during riding. In a vibrating environment, the stroke adjustment nut is not easy to maintain a fixed position, making it difficult to ensure the accuracy and stability of the motorcycle handle stroke. Utility Model Content

[0004] In order to solve the problems raised in the above-mentioned background technology, the utility model provides a motorcycle rocker arm with adjustable stroke, which solves the problem that the stroke adjustment nut is difficult to maintain a fixed position in a vibration environment, thereby making it difficult to ensure the accuracy and stability of the motorcycle handle stroke.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a motorcycle rocker arm with adjustable stroke, comprising a connecting block, a pin being provided inside the connecting block, the connecting block being connected to a handle via the pin, a spring being installed in the inner cavity of the handle, a stroke adjustment nut being installed at one end of the handle close to the spring, a positioning groove being machined on the back of the stroke adjustment nut, a positioning column being fixedly connected to one end of the connecting block close to the stroke adjustment nut, and a limit member being installed on the front of the connecting block;

[0006] The limiting member includes a limiting plate located on the front side of the connecting block, one end of the limiting plate is fixedly connected to a fixing column, and a rubber sleeve is provided inside the fixing column.

[0007] Preferably, a support is installed on one side of the connecting block, and a zipper adjustment nut and a brake switch are respectively installed on one end of the support, and the zipper adjustment nut is located above the brake switch.

[0008] Preferably, the inner cavity of the support is threadedly connected to a handle screw, and one end of the handle screw is threadedly connected to a nut.

[0009] Preferably, a small cover is installed at the bottom of the support, the bottom ends of the support and the small cover are both semicircular, and the bottom ends of the support and the small cover can be spliced ​​into a circle.

[0010] Preferably, the internal thread of the small cover is connected with a box cover screw, and there are two box cover screws, which are respectively located at both ends of the small cover, and the small cover is fixedly connected to the support through the two box cover screws.

[0011] Preferably, a handle is installed between the support and the bottom end of the small cover, and a through hole is opened on one side of the small cover.

[0012] Preferably, a plug hole is provided on the front of the connecting block, the plug hole is used to install a rearview mirror, and a retaining spring is installed at one end of the pin shaft.

[0013] Preferably, the connecting block and the support are fixed by a handle screw, and the bottom end of the spring is connected to the top surface of the connecting block.

[0014] Preferably, a threaded hole is provided on a side of the support opposite to the limiting plate, and a threaded bolt is provided inside the threaded hole.

[0015] Preferably, the limiting plate is connected to the support via a threaded bolt, and the fixing column and the rubber sleeve are both cylindrical.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] The utility model is provided with a pin shaft, a spring and a stroke adjustment nut, and the position of the stroke adjustment nut in the handle can be changed by rotating the stroke adjustment nut. The positioning groove on the back of the stroke adjustment nut cooperates with the positioning column at one end of the connecting block, which can play a role of positioning and stabilization when adjusting the stroke. When the stroke of the handle needs to be increased, the stroke adjustment nut is screwed out and the tail of the handle returns to bend upward. Conversely, when the stroke of the handle needs to be reduced, the stroke adjustment nut is screwed into the hole, and the tail of the handle will move downward. The back of the stroke adjustment nut is machined with a positioning groove. When the stroke adjustment nut is screwed to the appropriate position, the positioning column on the connecting block cooperates with the positioning groove to prevent the stroke adjustment nut from loosening. During the driving of the motorcycle, continuous vibration will be generated. Without the cooperation of the positioning groove and the positioning column, when the stroke adjustment nut is adjusted to a good position in the handle, it is easy to become loose or displaced due to vibration. Once this happens, the handle stroke will change, which will seriously affect the accuracy and stability of the operation.

[0018] The utility model inserts one end of the rearview mirror into the fixing column at one end of the limiting plate through the setting of the limiting piece, and sets a rubber sleeve inside the fixing column to increase friction or play a role of buffering, and connects the limiting plate to the support through the threaded bolt, so as to fix the limiting piece. The limiting piece is used to fix the rearview mirror, and a small cover is installed at the bottom of the support. The bottom ends of the small cover and the support are both semicircular, and the two can form a circle by splicing. The small cover is fixedly connected to the support through two box cover screws, and the connection between the fixing column at one end of the limiting plate and the rearview mirror is utilized, and the limiting plate is connected to the support through the threaded bolt, so as to form a stable fixing structure. This design can ensure that the rearview mirror remains stable during the driving of the motorcycle and will not be easily loosened or shifted due to vibration or bumps.
