Description

Technical Field

[0001] This application relates to the field of shock absorber technology, specifically to an adaptive electromagnetic damping adjustable motorcycle shock absorber. Background Technology

[0002] Motorcycle shock absorbers are an important component of motorcycles. Their main function is to mitigate and dampen the impact and vibration caused by uneven road surfaces during riding, ensuring a smooth and comfortable ride, and helping to improve the motorcycle's lifespan and handling stability.

[0003] Chinese patent document CN220134495U discloses an adjustable damping shock absorber, specifically including a mounting base, an outer cylinder, a cover, a piston rod, a piston assembly, and an inner cylinder. The mounting base connects to one end of the outer cylinder, the inner cylinder connects to the outer cylinder, and the cover connects the ends of the outer and inner cylinders. The piston rod is slidably connected to the cover, the piston assembly is connected to the end of the piston rod, and the piston assembly is slidably connected to the inner cylinder. The end of the inner cylinder away from the cover has two oil passage holes, a and b, allowing the oil tank and the oil storage tank to communicate with each other. An adjustment assembly is provided on the outer cylinder, and the adjustment assembly is connected to the oil passage hole a. In this embodiment, the adjustment assembly is located on the outer cylinder, making it more stable. The damping magnitude is further adjusted by moving the plug closer to or away from the oil passage hole a, thus regulating the flow rate of the oil. The operation of the adjustment assembly is simple and convenient.

[0004] However, in the aforementioned patent, the damping force of the shock absorber needs to be operated manually. This adjustment method cannot be adjusted randomly according to changes in road surface and load, making it difficult to meet market demands. Utility Model Content

[0016] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0017] like Figure 1-2As shown, an adaptive electromagnetic damping adjustable motorcycle shock absorber is characterized by comprising an inner cylinder 1 and an outer cylinder 2. The upper end of the inner cylinder 1 is sleeved inside the outer cylinder 2. A tension damping valve 21 is provided at the top of the inner side of the outer cylinder 2, and a compression damping valve 11 is provided at the bottom of the inner side of the inner cylinder 1. A piston body 12 is adaptedly provided inside the inner cylinder 1. A piston rod 13 is provided on the piston body 12. The piston rod 13 extends to the inner side of the outer cylinder 2. A locking block 22 is provided at the end of the piston rod 13 away from the piston body 12. The locking block 22 is used to lock the piston rod 13 and the tension damping valve 21.

[0018] Both the tension damping valve 21 and the compression damping valve 11 are solenoid valves. The tension damping valve 21 is used to regulate the flow rate of hydraulic oil in the outer cylinder 2, and the compression damping valve 11 is used to control the flow rate of hydraulic oil in the inner cylinder 1.

[0019] When the inner cylinder 1 and outer cylinder 2 are compressed, the hydraulic oil inside the outer cylinder 2 and inner cylinder 1 flows and compresses the working chamber inside the inner cylinder 1. Shock absorption is achieved through the compression and rebound of the gas within the working chamber. During the hydraulic oil flow, it passes through the tension damping valve 21 and the compression damping valve 11. At this time, the controller adjusts the required damping force according to the vehicle speed, that is, by controlling the opening of the tension damping valve 21 and the compression damping valve 11, the flow rate of the hydraulic oil is controlled, thereby achieving adaptive adjustment of the damping force and improving the user experience.

[0020] A valve body 14 is located above the piston body 12. The piston rod 13 is a hollow rod, and a valve rod 15 passes through the piston rod 13. One end of the valve rod 15 is connected to the valve body 14, and the other end of the valve rod 15 can slide within the piston rod 13. A variable resistor 16 is also provided on the inner side of the inner cylinder 1, and a terminal 17 is provided on the outer wall of the inner cylinder 1. The terminal 17 is used to electrically connect the controller and the variable resistor 16. The controller can control the resistance value of the variable resistor 16, thereby controlling the viscosity of the hydraulic oil inside the variable resistor 16. This further improves the control effect on the flow rate of the hydraulic oil, ensuring that the adjustment of the damping force is faster and more reliable.

[0021] Both the tension damping valve 21 and the compression damping valve 11 are equipped with electromagnetic actuators 110, which are used to control the opening degree of the tension damping valve 21 and the compression damping valve 11. After receiving a signal from the controller, the electromagnetic actuators 110 can quickly adjust the opening degree of the tension damping valve 21 and the compression damping valve 11, thereby quickly achieving the vibration reduction effect.

[0022] A limiting ring 18 is provided on the inner side of the inner cylinder 1, and a spring 19 is provided between the limiting ring 18 and the valve body 14. During the movement of the piston body 12, the valve body 14 and the valve stem 15 will be displaced. During the movement of the valve body 14, the spring 19 will be squeezed, thereby protecting the valve body 14 and also achieving a certain degree of shock absorption.

[0023] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
