Technical Field

[0001] This utility model relates to the field of motorcycle parts technology, and in particular to a high-strength motorcycle front fork tube. Background Technology

[0002] Existing electric bicycles and motorcycles are mostly composed of several major components: frame, motor, battery pack, and controller. By placing the controller, battery pack, motor, etc. in different positions of the vehicle, different types of electric vehicles can be formed.

[0003] The prior art discloses an electric bicycle, which consists of handlebars, a seat, a frame, front and rear wheels, a motor mounted on the central axle of the rear wheel, a battery, a driver, and a motor controller located between the two handlebars. The battery is installed in a battery box, which is inserted into a battery socket cavity.

The protective plate shell is installed at the bottom of the V-shaped triangle of the frame. The upper part of the cavity of the protective plate shell is the battery socket cavity. A socket plate is fixed on the battery socket cavity, and a pair of electrodes are provided on the socket plate. A pair of electrodes are provided on the battery. The battery is installed in the battery box, and the battery box is inserted into the socket plate through a socket plate. The socket plate slot and the socket plate engage to insert the battery box into the battery socket cavity, and the pair of electrodes on the battery contact the pair of electrodes on the socket plate. The pair of electrodes are connected to the driver through wires. Diagonal braces are provided on the front and rear sides of the battery.

[0004] However, the front fork tube of this type of vehicle has a relatively thin diameter, which makes it less able to withstand the strength when the vehicle is turning, making it prone to breakage and reducing its service life. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength motorcycle fork tube, which aims to solve the problem that the existing vehicle fork tubes have a small diameter, resulting in poor strength resistance when the vehicle is turning, easy breakage, and reduced service life.

[0006] To achieve the above objectives, this utility model provides a high-strength motorcycle fork tube, including a fork leg tube body. The fork leg tube body has a vertically arranged shaft hole, and the inner surface of the shaft hole is provided with an anti-corrosion galvanized layer. The bottom of the fork leg tube body is provided with a front wheel axle mounting hole, and the central axis of the front wheel axle mounting hole is perpendicular to the central axis of the fork leg tube body. The outer diameter of the fork leg tube body is 56mm.

[0007] The outer side of the front fork leg tube body is provided with a protective galvanized layer.

[0008] The bottom of the fork leg tube body is also symmetrically provided with reinforcing platforms.

[0009] The bottom of the fork leg tube body can also be detachably fitted with a decorative cover, which is located on one side of the front wheel axle mounting hole and is fixed by a locking mechanism provided on the fork leg tube body.

[0010] The locking mechanism includes a limiting screw and an anti-loosening nut. The limiting screw is integrally formed with the front fork leg tube body and is arranged in a ring around the outside of the front wheel axle mounting hole on the mounting part at the bottom of the front fork leg tube body. The anti-loosening nut is screwed onto the limiting screw.

[0011] This utility model discloses a high-strength motorcycle front fork tube. The front fork tube body has a vertically arranged shaft hole with an anti-corrosion galvanized layer on its inner surface. A front wheel axle mounting hole is located at the bottom of the front fork tube body, with the central axis of the mounting hole perpendicular to the central axis of the front fork tube body. The outer diameter of the front fork tube body is 56mm. This application sets the diameter of the front fork tube body to 56mm, resulting in greater strength, resistance to breakage, and a longer service life. Furthermore, the structure is simple and reasonable. By providing an anti-corrosion galvanized layer on the inner surface of the shaft hole, a high-strength acid and alkali resistant material effectively protects the interior of the tube body, preventing corrosion and damage from the inside out. This further strengthens the overall front fork tube body, thus solving the problem of existing vehicles having thinner front fork tube diameters, resulting in poor strength resistance during cornering, easy breakage, and reduced service life.

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of a high-strength motorcycle front fork tube. Figure 2 This is a bottom view of a high-strength motorcycle front fork tube. Figure 3 This is a schematic diagram showing the setting position of the limiting screw 108. This utility model provides a high-strength motorcycle fork tube: it includes a fork leg tube body 101 and a shaft hole 102 and a front wheel axle mounting hole 104 disposed on the fork leg tube body 101. The inner surface of the shaft hole 102 is provided with the anti-corrosion galvanized layer 103. The central axis of the front wheel axle mounting hole 104 is perpendicular to the central axis of the fork leg tube body 101. The outer diameter of the fork leg tube body 101 is 56mm. This solution solves the problem that existing vehicle fork tubes have a relatively thin diameter, resulting in poor strength resistance during cornering, easy breakage, and reduced service life. It is understood that this solution can improve the strength and service life of motorcycle fork tubes.

[0019] In this embodiment, the bottom of the front fork leg tube body 101 is a mounting part, and the top is a round tube part, which is made of high-strength stainless steel.

[0020] The fork leg tube body 101 has a vertically arranged shaft hole 102, and the inner surface of the shaft hole 102 is provided with an anti-corrosion galvanized layer 103. The bottom of the fork leg tube body 101 has a front wheel axle mounting hole 104, the central axis of which is perpendicular to the central axis of the fork leg tube body 101. The outer diameter of the fork leg tube body 101 is 56mm. The shaft hole 102 is vertically arranged, and the inner surface of the shaft hole 102 is provided with an anti-corrosion galvanized layer 103. The working principle of the anti-corrosion galvanized layer 103 is as follows: the galvanized layer is a zinc layer formed on the metal surface by hot-dip galvanizing or electroplating. Zinc is a reactive metal, highly reactive with oxygen, water, and other substances, forming a stable zinc oxide layer on the metal surface, which can effectively prevent metal oxidation and corrosion. It not only protects the metal surface from environmental erosion but also maintains the surface smoothness and aesthetics. During use, metal materials gradually age and fail due to oxidation, corrosion, and other reasons. The galvanized layer can prevent the above situation from occurring, thereby extending the service life of the metal. By setting the anti-corrosion galvanized layer 103 in the shaft hole 102, the service life of the front fork leg tube body 101 can be directly improved. Furthermore, the outer diameter of the tube body of the front fork leg tube body 101 is set to 56mm, which can further directly improve the strength and service life of the front fork leg tube body 101. The front wheel axle mounting hole 104 can be used for vehicle front wheel axle installation.

[0021] Secondly, a protective galvanized layer 105 is provided on the outer side of the front fork leg tube body 101. Similarly, by providing a protective galvanized layer 105 on the outer side of the front fork leg tube body 101, the service life of the front fork leg tube body 101 can be directly improved, thereby improving the service life of the vehicle's front fork tube.

[0022] Then, a reinforcing platform 106 is symmetrically provided at the bottom of the front fork leg tube body 101. The function of the reinforcing platform 106 is to improve the stability of the connection between the upper circular tube part and the lower mounting part of the front fork leg tube body 101, which helps to improve strength.

[0023] Furthermore, a decorative cover 107 can be detachably installed on the bottom of the front fork leg tube body 101. The decorative cover 107 is located on one side of the front wheel axle mounting hole 104 and is fixed by a locking mechanism provided on the front fork leg tube body 101. After the front wheel axle of the vehicle is installed, the decorative cover 107 is fixed by the locking mechanism on the front fork leg tube body 101, and the decorative cover 107 has a clearance cavity on the side facing the front wheel axle mounting hole 104.

[0024] Finally, the limiting screw 108 is integrally formed with the front fork leg tube body 101 and is annularly arranged on the outside of the front wheel axle mounting hole 104 on the mounting part at the bottom of the front fork leg tube body 101; the anti-loosening nut 109 is screwed onto the limiting screw 108. Four limiting screws 108 are provided and integrally formed with the front fork leg tube body 101 to ensure working strength and stability. The limiting screw 108 is a semi-threaded screw, that is, one side is a smooth shaft and the other side is a threaded end. The smooth shaft end is integrally formed with the front fork leg tube body 101, and the threaded end facilitates the installation of the anti-loosening nut 109.

[0025] To address the problem of existing vehicle fork tubes having a thinner diameter, resulting in poor strength resistance during cornering, easy breakage, and reduced service life, this utility model firstly addresses this issue by vertically configuring the shaft hole 102 on the fork leg tube body 101 and providing an anti-corrosion galvanized layer 103 on the inner surface of the shaft hole 102, thereby improving the service life of the fork leg tube body 101. Furthermore, by providing the front wheel axle mounting hole 104 at the bottom of the fork leg tube body 101, front wheel axle installation is facilitated. The central axis of the front wheel axle mounting hole 104 is perpendicular to the central axis of the fork leg tube body 101. The outer diameter of the fork leg tube body 101 is set to 56mm. Therefore, this application improves the service life of the fork leg tube body 101. The diameter is set to 56mm, which makes the entire front fork leg tube body 101 strong, not easy to be twisted and broken, and has a long service life. The structure is simple and reasonable. Furthermore, by setting the anti-corrosion galvanized layer 103 on the inner surface of the shaft hole 102, the tube body is well protected by high-strength acid and alkali resistant material to prevent corrosion and damage from the inside out. This further strengthens the overall front fork leg tube body 101. At the same time, a protective galvanized layer 105 is set on the outer side of the front fork leg tube body 101, which can further improve the service life. This can solve the problem that the existing vehicle front fork tubes are too thin, which have poor strength resistance when the vehicle is turning, are easy to break, and have a reduced service life.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
