Problems solved by technology

[0003] 1) The spring has a large degree of freedom. When the vehicle is overloaded, it cannot resist the left and right swing of the engine. In this way, the left and right swing of the engine is relatively large, reaching 20-30mm, which will cause damage to the reverse gear, transmission shaft or muffler.
[0004] 2) The spring is prone to fatigue, not durable, and the service life is not guaranteed
[0005] 3) The shock absorption effect is poor, which will affect the driving comfort
[0006] 4) The exposed spring will affect the appearance of the three-wheeled motorcycle

Embodiment 1

[0024] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the present embodiment is made of rubber cover 1, upper base 2, upper screw rod 3, lower base 4, lower screw rod 5, upper connecting buckle 7, lower connecting buckle 8, metal inlaid ring 9 and rubber sleeve 10, etc. Wherein, the rubber cover 1 has holes along the axis line, and the upper and lower ends of the rubber cover 1 are open. An upper base 2 is arranged on the upper end of the rubber cover 1, and the upper base 2 is circular, and is fixed with the rubber cover 1 through vulcanization molding. The edge of the upper base 2 is flanged downwards to form an upper skirt 2a, and the upper skirt 2a is wrapped in the rubber outer cover 1 . The upper screw rod 3 is arranged at the central position of the upper base 2, and the upper screw rod 3 is perpendicular to the upper base 2, and the lower end of the upper screw rod 3 is fixed with the upper base 2. The upper base 2 seals the upper port of the rubber...

Embodiment 2

[0031] In this embodiment, the airtight chamber 6 is provided with air whose pressure is equal to that of the external atmosphere. The rest of the structure of this embodiment is the same as that of Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a shock absorber. The two ends of an outer rubber cover (1) are open. An upper base (2) is fixed to the upper end of the outer rubber cover (1). A lower base (4) is fixed to the lower end of the outer rubber cover (1). The two ends of the outer rubber cover (1) are sealed through the upper base (2) and the lower base (4) respectively. A closed cavity (6) is formed in the outer rubber cover (1). An upper connecting buckle (7) and a lower connecting buckle (8) which are fastened with each other are arranged in the closed cavity (6). The shock absorber is ingenious in design, simple in structure and easy to operate; the double shock absorption effect achieved through the outer rubber cover and pressure gas is good, vehicle body vibration can be effectively reduced, and riding comfort is greatly improved; meanwhile, the lateral oscillating quantity of an engine in the overload process can be reduced within 5 mm, so that a reverse gear device and a transmission shaft cross-shaped joint are effectively prevented from being damaged or a silencer is effectively prevented from being broken.

Description

technical field [0001] The invention belongs to the technical field of shock absorption, and in particular relates to a shock absorber. Background technique [0002] At present, the shock absorbers used for engine shock absorption on three-wheeled motorcycles are generally spring-type structures, and the springs mainly play the role of shock absorption. The existing deficiencies are: [0003] 1) The spring has a large degree of freedom. When the vehicle is overloaded, it cannot resist the left and right swing of the engine. In this way, the left and right swing of the engine is relatively large, reaching 20-30mm, which will cause damage to the reverse gear, transmission shaft or muffler. . [0004] 2) The spring is prone to fatigue, not durable, and the service life is not guaranteed. [0005] 3) The damping effect is relatively poor, which will affect the comfort of driving. [0006] 4) The spring is exposed, which will affect the aesthetic appearance of the three-wheele...
