In the process, the hole diameter of a hole b communicated with a hole c is changed by rotating a rotary knob, control over flow is achieved, the larger the hole diameter of the hole b is, the higher the flow speed is, the softer the rod body moves, and the harder the rod body moves, so that the steering handle is suitable for driving on different road surfaces.

Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle accessories, in particular to a rotary adjustable damper. Background Art

[0002] The steering damper on a motorcycle, also known as an "anti-tank slapper", has a structure including a needle, a sleeve, and a push rod. The function of the steering damper is to slow down the frequency and amplitude of the handlebar swing in situations such as high-speed driving, full-throttle start, and crossing ditches and bumps, and improve the stability of the vehicle when cornering.

[0003] The steering damper is like a double-edged sword. Just like a shock absorber, pursuing handling means sacrificing comfort, and vice versa. The better the damping effect of the steering damper, the lower the flexibility of the vehicle. When the vehicle flexibility increases, the risk of head shaking at high speeds also increases. The damping effect of existing dampers cannot be adjusted and cannot be adaptively adjusted according to the driving road conditions, which has certain limitations. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a rotary adjustable damper.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A rotary adjustable damper includes a cylinder block and an inner cylinder body located therein. Both ends of the inner cylinder body are fixed to the cylinder block through end caps and threaded plugs. The inner cylinder body divides the cylinder block into an inner cavity and an outer cavity. A piston a is arranged in the inner cavity. A rod body is installed on the piston a. Both ends of the rod body respectively penetrate through the end cap and the threaded plug. One end of the cylinder block is sleeved with a sealing sleeve. A piston cylinder is connected to the sealing sleeve. A piston mechanism is arranged in the piston cylinder. An annular cavity is arranged between the sealing sleeve and the cylinder block. A hole a communicating the annular cavity and the outer cavity is arranged on the side wall of the cylinder block. The annular cavity communicates with the piston cylinder through a hole d. A hole c is arranged on the threaded plug. The hole c communicates the inner cavity and the outer cavity. A flow rate regulating mechanism is arranged at the inner end of the hole c.

[0007] Preferably, the flow rate regulating mechanism includes a knob rotatably connected inside the threaded plug. A rotary damping mechanism is arranged between the knob and the threaded plug. A hole b opposite to the hole c is arranged on the knob. The hole b is annularly distributed, and the inner diameter of the hole b gradually increases in sequence.

[0008] Preferably, the piston mechanism includes a piston b. The piston b is connected inside the piston cylinder through an elastic member.

[0009] Preferably, protective rings are arranged on both sides of the piston a. The protective rings are sleeved on the rod body. A sealing ring is sleeved on the piston a.

[0010] Preferably, sealing structures are provided at the joints of the knob and the end cap with the rod body.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: In the present utility model, the inner cavity on the right side of piston a is filled with hydraulic oil. When the steering handle drives the rod body to move to the right, piston a squeezes the hydraulic oil, which enters the outer cavity through hole b and hole c, then enters the annular cavity through hole a, and then enters the piston cylinder through hole d to drive piston b to move. Conversely, when the steering handle drives the rod body to move in the reverse direction, the flow direction of the hydraulic oil is opposite, so as to buffer the jitter of the steering handle and ensure driving safety. During this process, by rotating the knob, the aperture of hole b communicating with hole c is changed to control the flow rate. The larger the aperture of hole b, the faster the flow rate, and the softer the movement of the rod body; on the contrary, the harder it is, so as to meet the driving needs on different road surfaces.
