When the front wheel bounces, it will cause a vibration feeling in the vehicle, reducing the comfort of riding and the stability of handling; 2. Due to the simple structure, the design freedom is small and the handling stability is poor; 3. The vibration buffer for riding is not good, and the riding comfort and smoothness are poor; 4. For the upright cylinder type shock absorber, reciprocating motion generates friction and easily wears the shock absorber cylinder to generate gaps, resulting in poor controllability; 5. For the upright cylinder type shock absorber, when hitting obstacles with relatively large bumps on the road surface, it is easy to bend or break; Therefore, a front shock absorber device for a three-wheel passenger vehicle is proposed to solve the above problems.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 4, A front shock absorber device for a three-wheeled passenger vehicle in this embodiment includes a steering shaft 1, a lower link plate 2, two front arms 3, two swing arms 4, a damping shock absorber 5, a set of wheels 9, a set of brakes, a mudguard 11, a swing arm bearing 12, and a wheel 10;

[0021] The steering shaft 1 is fixedly installed on the lower link plate 2. The two front arms 3 are fixedly installed on the lower link plate 2. The swing arm 4 is rotatably connected to the front arm 3. A swing arm bearing 12 is provided at the lower end of the front arm 3. The lower end of the front arm 3 is rotatably connected to the swing arm 4 through the swing arm bearing 12. The wheel hub 9 is provided on the swing arm 4. A rotating shaft is provided at one end of the swing arm 4 away from the front arm 3. The wheel hub 9 is rotatably connected to the swing arm 4 through the rotating shaft;

[0022] The damping shock absorber 5 is hinged between the front arm 3 and the swing arm 4. The mudguard 11 is fixedly connected to the inner side of the front arm 3. The wheel hub 9 is rotatably connected to the swing arm 4;

[0023] A set of brakes consists of a brake pump bracket 6, a brake pump 7, and a brake disc 8. The brake pump bracket 6 is fixed on the rotating shaft of the swing arm 4. The brake pump 7 is fixedly installed on the brake pump bracket 6. The brake disc 8 is fixed on the wheel hub 9 and is located inside the brake pump bracket 6. The brake disc 8 is braked by the brake pump 7 located on the brake pump bracket 6 to achieve the effect of stopping.

[0024] In this embodiment, when the front wheel, i.e., the wheel 10, moves up and down, it relies on the up and down rotational movement of the center of the swing arm 4 to achieve the movement, and is connected to the damping shock absorber 5 with rubber sleeves installed at both ends, which improves the body stability and comfort; reduces the vibration of the frame and the body, improves the driving and steering comfort, increases the lateral, longitudinal, and up and down load-bearing mass of the front wheel, i.e., the wheel 10, reduces the impact load on the frame, and when hitting a relatively large bump on the road surface during driving, it will not bend or break, improving driving safety; when the vehicle is driving at high speed, it improves the riding comfort and stability; the up and down movement space of the front wheel, i.e., the wheel 10, is increased, which can improve its passing performance and driving smoothness.

[0025] The working principle of the above embodiment is as follows:

[0026] When the vehicle is driving, steering is achieved through the fixed shock absorber device of the steering shaft 1 and the frame. During driving, when the wheel 10 rotates, the wheel hub 9 of the wheel 10 moves up and down due to the uneven road surface. The swing arm 4 is driven to swing up and down through the swing arm bearing 12, pushing the damping shock 5 and the front arm 3 to form different distances to achieve the shock absorption effect. When braking or stopping is required, it is achieved through the friction of the brake pump bracket 6, the brake pump 9, and the brake disc 8. The muddy water during driving is blocked by the mudguard 11. In this way, the movement can achieve the comfort, smoothness, stability, safety, and driving smoothness of the vehicle.
