[0010] Compared with the prior art, this utility model provides a front wheel shock absorber for a three-wheeled motorcycle, which has the following beneficial effects:

[0011] This type of front wheel shock absorber for three-wheeled motorcycles consists of a pressure plate, frame, shaft, elliptical wheel, compression rod, and sleeve plate. The pressure plate can be pressed down or lifted up, causing the frame to rotate. This, in turn, drives the elliptical wheel to rotate via the shaft. Under the action of the guide plate, the compression rod is compressed upwards, causing the sleeve plate to move upwards. At this point, the adjusting sleeve can be rotated to the appropriate position, and the tension of the telescopic spring can be adjusted under the action of the fixing block, thus achieving the purpose of adjusting the front wheel shock absorber of the three-wheeled motorcycle.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3In this embodiment: a front wheel shock absorber for a three-wheeled motorcycle includes a front fork 1, with dampers 3 on both sides of the front fork 1. An adjusting sleeve 4 is provided on the outer ring of the outer shell of the damper 3 for adjustment. Fixing blocks 14 are fixedly installed on both sides of the outer shell of the damper 3. Rotating shafts 13 are rotatably connected to both sides of the damper 3. Elliptical wheels 6 are installed at the ends of the two rotating shafts 13 that are far apart from each other. Rotating shafts 13 can drive elliptical wheels 6 to rotate. A pressing rod 5 is provided on the upper part of the elliptical wheel 6. Rotating elliptical wheels 6 can press against the pressing rod 5. A frame 7 is installed on the outer ring of the rotating shafts 13, and a pressure plate 8 is welded to one side of the frame 7. The pressure plate 8 can be pressed down or lifted up, which can drive the frame 7 to rotate.

[0018] In this embodiment, both sides of the adjusting sleeve 4 are stepped, and grooves are provided on the stepped surfaces of the adjusting sleeve 4. The top of the fixing block 14 matches the grooves on the stepped surfaces of the adjusting sleeve 4, allowing the adjusting sleeve 4 to be rotated to the corresponding position. Under the action of the fixing block 14, the tension of the telescopic spring 10 can be adjusted. The frame 7 is U-shaped, and one end of the U-shaped frame 7 is fixedly installed on the outer ring of the two rotating shafts 13. When the frame 7 rotates, the rotating shafts 13 can rotate. Guide plates 12 are welded to both side walls of the outer shell of the damper 3, and the compression rod 5 passes through the guide plate. Guide plate 12, under the action of guide plate 12, can make the compression rod 5 move vertically. Inside the damper 3, there is a piston rod 2 extending to the upper part of the damper 3. A fixing plate 11 is fixedly installed on the upper outer ring of the piston rod 2. A telescopic spring 10 is fixedly installed on the bottom surface of the fixing plate 11, which surrounds the outer ring of the piston rod 2. The lower part of the telescopic spring 10 surrounds the upper outer ring of the damper 3. A sleeve plate 9 is fixedly installed on the middle outer ring of the damper 3. The lower end of the telescopic spring 10 is fixedly installed on the top surface of the sleeve plate 9. The damper 3 and the telescopic spring 10 work together to play a role in shock absorption.

[0019] The working principle and usage process of this utility model are as follows: When adjusting the front wheel shock absorber of a three-wheeled motorcycle, the pressure plate 8 can be pressed down with the foot. This can be done by squatting or lifting the pressure plate 8, which rotates the frame 7, causing the rotating shaft 13 to rotate. The rotating shaft 13 then rotates the elliptical wheel 6. Under the action of the guide plate 12, the elliptical wheel 6 can press the compression rod 5 upwards, which in turn presses the sleeve 9 upwards, causing the sleeve 9 to move upwards. The adjusting sleeve 4 can then be rotated to the corresponding position. By rotating the adjusting sleeve 4 and under the action of the fixing block 14, the tension of the telescopic spring 10 can be adjusted, thus achieving the purpose of adjusting the front wheel shock absorber of the three-wheeled motorcycle.
