DETAILED DESCRIPTION

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figure 1-Figure 3As shown in the figure, a split motorcycle rear fork structure with a pedal includes two rear fork side plates 1 and an upper fork frame 2 that are symmetrically arranged on the left and right. The tail ends of the rear fork side plates 1 have a connecting portion 11 and a connecting ear 12 for connecting the rear fender and the shock absorber respectively. A U-shaped groove 13 for connecting the rear wheel is opened at the tail end of the rear fork side plate 1. It is characterized in that it further includes a pedal 3 and a square tube 4 corresponding to the rear fork side plates 1 one by one. The upper fork frame 2 is in a U shape. The upper fork frame 2 is attached to the heads and tails of the two rear fork side plates 1 and fixed by a first bolt 5. A first sliding groove 14 is opened on the outer side surface of the rear fork side plate 1, and second sliding grooves 21 connected to the first sliding groove 14 are opened on both sides of the upper fork frame 2. A number of circular sliding holes 22 arranged in a line are opened at the bottoms of the first sliding groove 14 and the second sliding groove 21, and a strip-shaped fixing hole 23 is opened below the sliding hole 22. The pedal 3 includes a stepping portion 31 and a side portion 32 vertically and fixedly connected to the stepping portion 31. The side portion 32 is arranged in the first sliding groove 14 and the second sliding groove 21. A connecting hole 321 docked with the fixing hole 23 is opened on the side portion 32. The side portion 32 is fixed to the fixing hole 23 by a second bolt 6. A pair of pull rods 33 are connected to the inner side of the side portion 32. The pair of pull rods 33 slidably pass through the sliding holes 22. The outer end of the pair of pull rods 33 has a thread. The pair of pull rods 33 slidably pass through the square tube 4 and are in threaded cooperation with the square tube 4.

[0020] During installation, first, the upper fork frame 2 is attached to the heads and tails of the two rear fork side plates 1 and fixed by a first bolt 5. The side portion 32 of the pedal 3 is clamped into the first sliding groove 14 and the second sliding groove 21 and adjusted to an appropriate position. The pair of pull rods 33 are passed through the sliding holes 22 and slidably pass through the square tube 4. By rotating the square tube 4, a clamping prestress is generated inward on the side portions 32 on both sides. The upper fork frame 2 is connected to the rear fork side plates 1 and forms an internal support for them, and is combined with the prestress of the side portion 32 of the pedal 3 to improve the connection strength between the rear fork side plates 1 and the upper fork frame 2.

[0021] The outer side surface of the rear fork side plate 1 is flush with the side surface of the upper fork frame 2, so that the connection between the outer side surface of the rear fork side plate 1 and the side surface of the upper fork frame 2 is smooth.

[0022] The side length of the square tube 4 is 12 - 20 mm, which is used to cooperate with the upper fork frame 2 to ensure that there is sufficient strength for the pulling force in cooperation with the pair of pull rods 33.

[0023] The middle part of the rear fork side plate 1 is hollowed out, and a metal partition net 7 covering the hollow opening is fixed inside it. While ensuring the strength of the rear fork side plate 1, hollowing out its middle part greatly reduces its overall mass and the side wind pressure during the vehicle's driving. The metal partition net 7 can prevent gravel or other solid impurities from entering through the hollow opening during the motorcycle's driving and damaging the tire.

[0024] The inner side of the rear fork side plate 1 is provided with a limiting groove 15, and both sides of the upper fork frame 2 are protruded to form limiting parts 24 inserted into the limiting groove 15. The limiting groove 15 cooperates with the limiting part 24 to prevent the first bolt 5 from loosening under the condition of long-term vibration of the vehicle, thereby preventing displacement between the rear fork side plate 1 and the upper fork frame 2.

[0025] Furthermore, the tie rod 33 is located directly below the pedal portion 31 , and the connection between the tie rod 33 and the side portion 32 is hidden below the pedal portion 31 , thereby ensuring aesthetics and safety in use.

[0026] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
