Description

Technical Field

[0001] The invention relates to the technical field of shock absorbers, in particular to a shock absorber with buffer damping. Background Art

[0002] Shock absorbers are used to suppress the shock caused by the rebound of the spring after absorbing the shock and the impact from the road surface. They are widely used in automobiles to accelerate the attenuation of the vibration of the frame and body to improve the driving smoothness of the car. When the piston reciprocates in the cylinder, the oil in the shock absorber flows back and forth between the two mutually isolated inner cavities through the narrow pores on the valve. Due to the friction between the pore wall and the oil and the internal friction of the liquid molecules, a damping force is formed, thereby converting the mechanical energy of the body vibration into heat energy which is absorbed by the oil and the shell.

[0003] In the prior art, some shock absorbers are equipped with gas cylinders to make the damping of the shock absorbers smoother. However, when the temperature rises, the gas pressure in the gas cylinder increases, which makes the gas difficult to compress, and directly affects the shock absorbing effect of the shock absorber, resulting in a weakened shock absorbing effect. In addition, under colder conditions, the gas cylinder has no thermal insulation effect, and the material of the seal may become brittle or soft, causing the shock absorber to leak.

[0015] The present invention has the following beneficial effects:

[0016] (1) The present invention is provided with a temperature regulating cylinder. When the temperature of the gas cylinder or the outside temperature is high, the motor works and is threadedly connected with the connecting thread through the threaded rod. In combination with the limiting effect of the limiting rod on the limiting cylinder, the temperature regulating cylinder is pushed downward, and the top of the gas cylinder is exposed to the air, thereby increasing the contact area with the air and improving the heat dissipation effect.

[0017] (2) When the temperature inside the gas cylinder or the outside temperature is too low, the motor of the present invention starts to work, driving the temperature regulating tube to move upward, and the gas cylinder will shrink into the inside of the temperature regulating tube. The vacuum inside the temperature regulating tube is used to isolate the gas cylinder from the outside air, thereby keeping the gas cylinder warm, thereby preventing the seal from becoming brittle or soft due to the low temperature, which may cause leakage of the shock absorber.

[0018] (3) In the present invention, when the temperature regulating cylinder moves downward, the pressure regulating rod moves downward synchronously, the length of the pressure regulating rod between the floating piston plate and the base is shortened, and the volume between the floating piston plate and the base is increased, thereby further reducing the gas pressure inside the gas cylinder and preventing the gas pressure inside the gas cylinder from being too high, resulting in a weakened shock absorption effect;

[0019] When the temperature regulating cylinder moves upward, the pressure regulating rod moves upward synchronously, the volume of the top of the pressure regulating rod extending into the space between the floating piston disc and the base increases, the volume of the space between the floating piston disc and the base decreases, and the air pressure increases, thereby compensating for the volume contraction of the gas at low temperature, thereby ensuring the stability of the shock absorber during operation.

[0043] Example 2

[0044] See also Figure 7 - Figure 8 As shown, a side of the bottom of the fixing plate 51 away from the motor 52 is fixedly connected to a limiting rod 511, and the limiting rod 511 is slidably disposed inside a limiting cylinder 53 away from the threaded rod 521;

[0045] When the motor 52 is working, the threaded rod 521 is threadedly connected with the connecting thread 531, and the limiting rod 511 cooperates with the limiting effect of the limiting cylinder 53 to control the temperature regulating cylinder 5 to move up and down;

[0046] A pressure regulating rod 54 is fixedly connected to the central axis of the temperature regulating cylinder 5, and the pressure regulating rod 54 is slidably arranged inside the base 46;

[0047] By extending one end of the pressure regulating rod 54 to the inside of the floating piston disc 45 and the base 46, when the gas cylinder 4 and the temperature regulating cylinder 5 move relative to each other, the length of the pressure regulating rod 54 extending between the floating piston disc 45 and the base 46 will be changed, thereby changing the volume of the space between the floating piston disc 45 and the base 46 to adjust the gas pressure inside the gas cylinder 4.

[0048] A mounting thread 541 is provided at the top of the inner wall of the pressure regulating rod 54, a slot 2 55 is provided at the bottom of the temperature regulating tube 5, a clamping nut 56 is arranged inside the pressure regulating rod 54, the clamping nut 56 is threadedly connected with the mounting thread 541, a sealing gasket 57 is sleeved on the clamping nut 56, and the nut of the clamping nut 56 presses the slot 2 55 inside the slot 2 55, a groove 8 58 is provided at the top of the temperature regulating tube 5, a sealing ring 8 581 is arranged inside the groove 8 58, and a clamping cover 59 is fixedly installed on the top of the temperature regulating tube 5.

[0049] When in use, when encountering bumps, the barrel body 1 and the piston rod 2 will move relative to each other. When the piston rod 2 slides toward the inside of the barrel body 1, the piston plate 22 moves synchronously. The piston plate 22 pushes a portion of the hydraulic oil into the gas cylinder 4 through the connecting pipe 1131, and then pushes the floating piston plate 45 to slide downward inside the gas cylinder 4, and the gas between the floating piston plate 45 and the base 46 is compressed.

[0050] When the piston plate 22 moves upward inside the barrel body 1, the oil pressure at the top of the piston plate 22 is greater than the pressure at the bottom of the piston plate 22, and the hydraulic oil will push the valve plate 224 to open the valve plate 224, so that the hydraulic oil can flow to the bottom of the piston plate 22. In addition, the hydraulic oil at the top of the piston plate 22 can also flow into the bottom of the piston plate 22 through the central tube 225, the connecting hole 202 and the bypass hole 203, so as to control the flow rate of the hydraulic oil and achieve a buffering and damping effect.

[0051] When the spring 3 rebounds, the piston plate 22 moves downward inside the barrel 1, and the hydraulic oil at the bottom of the piston rod 2 is pressured to flow back to the top of the piston plate 22 through the bypass hole 203, the connecting hole 202 and the center tube 225;

[0052] By adjusting the setting of the nut 25, the adjusting nut 25 is screwed, so that the adjusting nut 25 moves inside the deep hole 24, and then the movable rod 23 is pushed to move up and down through the connection between the inclined surface 251 and the bottom spherical surface of the movable rod 23, so that the size of the opening between the conical head 231 and the conical groove 226 can be changed, thereby achieving the effect of changing the damping size;

[0053] By providing the temperature regulating cylinder 5, when the temperature of the gas cylinder 4 changes, the motor 52 will be controlled by the temperature change signal to rotate forward and reverse. When the temperature of the gas cylinder 4 or the external temperature is high, the motor 52 works, and the threaded rod 521 is threadedly connected with the connecting thread 531, and the limiting rod 511 cooperates with the limiting effect of the limiting cylinder 53, which will push the temperature regulating cylinder 5 downward, and the top of the gas cylinder 4 will be exposed to the air, thereby increasing the contact area with the air and improving the heat dissipation effect.

[0054] In addition, when the temperature regulating cylinder 5 moves downward, the pressure regulating rod 54 moves downward synchronously, the length of the pressure regulating rod 54 between the floating piston plate 45 and the base 46 is shortened, and the volume between the floating piston plate 45 and the base 46 is increased, thereby further reducing the gas pressure inside the gas cylinder 4, and preventing the gas pressure inside the gas cylinder 4 from being too high, resulting in a weakened shock absorption effect;

[0055] When the temperature inside the gas cylinder 4 or the outside temperature is too low, the motor 52 works to drive the temperature regulating cylinder 5 to move upward, and the gas cylinder 4 will shrink into the inside of the temperature regulating cylinder 5. The gas cylinder 4 is isolated from the outside air by the vacuum inside the temperature regulating cylinder 5, and the gas cylinder 4 is kept warm to prevent the seal from becoming brittle or soft due to the low temperature, which may lead to leakage of the shock absorber.

[0056] When the temperature regulating cylinder 5 moves upward, the pressure regulating rod 54 moves upward synchronously, the volume of the top of the pressure regulating rod 54 extending into the space between the floating piston disk 45 and the base 46 increases, the volume of the space between the floating piston disk 45 and the base 46 decreases, and the air pressure increases, thereby compensating for the volume of the gas contraction at low temperature, thereby ensuring the stability of the shock absorber during operation.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described.
