[0002] With the improvement of living standards, karts have become a common competitive and recreational vehicle in people's daily lives.

[0003] The kart's steering is a traditional pull-rod structure without any resistance devices. The basic handling quality of the kart is achieved by setting the kingpin caster angle and inclination angle. This basic physical setting either takes care of the stability of the steering at high speed by increasing the steering force, or loses high-speed stability by reducing the steering force. The steering damper can quickly solve the problem of rapid adjustment of the steering weight. Utility Model Content

[0010] Optionally, the rotary piston is provided with an upper O-ring and a lower O-ring on the upper and lower sealing ring grooves respectively.

[0011] Optionally, a scale is provided on the rotary oil valve.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model controls the steering of the eccentric oil tank by twisting the rotary oil valve. The eccentric oil tank controls the flow rate of the hydraulic oil, and the flow rate of the hydraulic oil is controlled to achieve rotary damping. By adjusting the rotary damping, the kart can realize rapid weight adjustment of the steering wheel according to the driver's needs when driving at high speed or low speed, so that when the driver faces the steering reaction of the steering wheel causing the direction to deviate, it plays a damping role, allowing the driver to have sufficient reaction time to control the direction, thereby greatly improving the safety of driving the kart.

[0014] The housing of the utility model is provided with a retaining spring at the installation position of the rotary oil valve. The rotary oil valve is fixed in the housing by the retaining spring, so that the position of the eccentric oil groove does not change, thereby improving the damper's reduction efficiency and further ensuring the driver's driving safety.

[0015] The utility model is provided with a push plate on the rotary piston. When the driver turns the steering wheel, the push plate on the rotary piston squeezes the hydraulic oil through the eccentric oil groove to achieve steering wheel damping, thereby providing the driver with a buffered reaction time when turning the steering wheel, thereby ensuring improved kart driving stability.

[0016] The upper cover, rotary piston and rotary oil valve of the utility model are all provided with sealing rings, which can effectively seal the oil inside the hydraulic damper, ensuring the normal operation of the hydraulic system and avoiding leakage or seepage. The sealing ring can also provide a certain friction resistance, making the movement process of the damper more stable and reducing impact force and vibration. The sealing ring also has good wear resistance and corrosion resistance, and can adapt to high temperature, low temperature and chemical media in different working environments.

[0017] The utility model provides a scale on the rotary oil valve, which can display the degree of lightness or heaviness of the steering wheel. The user can twist the rotary oil valve to select the degree of lightness or heaviness that suits the user, thereby further increasing the safety when driving the kart.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] According to the above solution, when steering a go-kart, the driver turns the steering wheel. In a damper for adjusting the steering wheel of the go-kart, a rotary piston 3 is connected to a steering rod by a screw. A push plate 14 is provided on the rotary piston 3. When steering, the driver turns the steering wheel so that the push plate 14 on the rotary piston 3 squeezes the hydraulic oil through the eccentric oil groove 17 to achieve steering wheel damping. This provides the driver with a buffered reaction time when turning the steering wheel, thereby ensuring improved driving stability of the go-kart.

[0030] The first installation cavity 12 is provided with a first oil cavity 15 and a second oil cavity 16 on both sides thereof. The second installation cavity 13 is connected to the first oil cavity 15 and the second oil cavity 16 on both sides thereof through oil grooves. The eccentric oil groove 17 is connected to the oil groove.

[0031] With the above solution, the driver controls the steering of the eccentric oil tank 17 by twisting the rotary oil valve 1. The eccentric oil tank 17 controls the flow rate of the hydraulic oil, and thus controls the flow rate of the hydraulic oil to achieve rotational damping. By adjusting the rotational damping, the kart can achieve rapid weight adjustment of the steering wheel according to the driver's needs when driving at high or low speeds, thereby playing a damping role when the driver faces the steering reaction of the steering wheel causing the direction to deviate, so that the driver has sufficient reaction time to control the direction, thereby greatly improving the safety of the kart.

[0032] Among them, the main body 6 and the upper cover 2 constitute a shell, the bottom of the shell can be connected to the steering wheel rod, the upper cover 2 and the main body 2 can be detachably installed, the upper cover 2 and the main body 2 are fixed by fixing screws, and the shell is provided with a retaining spring 11 at the installation position of the rotary oil valve 1, and the two ends of the retaining spring are respectively connected to the rotary oil valve 1 and the second installation cavity 13.

[0033] With the above solution, when the driver or staff installs the damper on the kart, a retaining spring 11 is arranged at the installation position of the rotary oil valve 1 on the body 6. The rotary oil valve 1 is fixed in the body 6 by the retaining spring 11, so that the position of the eccentric oil groove 17 does not change, thereby improving the damping efficiency of the damper and ensuring the safety of the driver during driving.

[0034] The rotary oil valve 1 is provided with a rotary oil valve upper sealing ring 9 and a rotary oil valve lower sealing ring 10 on the upper and lower sealing ring grooves respectively, an upper cover sealing ring 4 is provided at the bottom of the upper cover 2, and a rotary piston upper O-ring 5 and a rotary piston lower O-ring 7 are provided on the upper and lower sealing ring grooves of the rotary piston 3 respectively, and a scale 18 is provided on the rotary oil valve 1.

[0035] Adopting the above scheme: the upper cover 2, the rotary piston 3, and the rotary oil valve 1 are all provided with sealing rings, which can effectively seal the oil inside the hydraulic damper, ensure the normal operation of the hydraulic system, and avoid leakage or seepage; the sealing ring can also provide a certain friction resistance, making the movement process of the damper more stable, reducing impact force and vibration; the sealing ring also has good wear resistance and corrosion resistance, and can adapt to high temperature, low temperature and chemical media in different working environments.

[0036] The working principle and use process of this utility model:

[0037] When the user turns the steering wheel, the rotary piston 3 in the housing also rotates. A push plate 14 is provided on the rotary piston 3. The rotary piston 3, which is connected to the steering column, squeezes the hydraulic oil in the first and second oil chambers left and right through the push plate 14 to pass through the rotary oil valve 1. The flow rate of the hydraulic oil is then controlled by the eccentric oil groove 17 in the rotary oil valve 1 to achieve rotary damping. The user can observe the scale 18 and then adjust the rotary damping by twisting the rotary oil valve 1. This allows the kart to quickly adjust the steering wheel weight according to the driver's preference when driving at high or low speeds. The sealing ring in the main body 6 can effectively seal the oil inside the hydraulic damper, ensuring the normal operation of the hydraulic system and avoiding leakage or seepage. The retaining spring 11 in the main body is used to fix the rotary oil valve 1, making it difficult for the rotary oil valve 1 to fall off.
