Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle and electric vehicle steering accessory safety, and particularly relates to a steering damper for motorcycles and electric vehicles. Background Art

[0002] Nowadays, motorcycles and electric vehicles are developing towards the trend of light weight and large horsepower. And many high-end large-displacement models are equipped with electronic devices to ensure the safety and stability of vehicle driving. Therefore, some safety devices need to be installed, such as the steering damper of motorcycles and electric vehicles. It is installed at the front end of motorcycles and electric vehicles. The function of the steering damper is to damp the behavior of attempting to rotate the handlebar irregularly and widely within a short time due to the action of road surface or human external force during high-speed driving;

[0003] When the motorcycle or electric vehicle is in a high-speed state, it can also prevent the front end from swinging excessively. When cornering at high speed, it can attenuate the vibration feeling brought to the rider due to the excessive swing of the handlebar caused by the uneven road surface;

[0004] Secondly, during the use process, due to the loss of damping oil, the oil pressure in the upper oil chamber and the lower oil chamber is insufficient, which will cause gaps to occur when the piston moves, thus affecting the driving comfort;

[0005] Now, a steering damper for motorcycles and electric vehicles is proposed, so that the damper always works in an ideal state, without affecting the driving safety of the driver and increasing the stability of the handlebar during vehicle driving, and improving the driving comfort. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide a steering damper for motorcycles and electric vehicles to meet the current needs of the general public.

[0007] The purpose of the utility model can be achieved by the following technical solutions:

[0008] A steering damper for motorcycles and electric vehicles, comprising:

[0009] A damper body, and the damper body is provided with a piston traction mechanism that moves in the piston chamber, an external connection part opposite to the piston traction mechanism, and a replenishment part communicated with the piston chamber;

[0010] The piston traction mechanism divides the piston cavity into an upper oil cavity and a lower oil cavity through a piston part and a valve plate group. The upper oil cavity and the lower oil cavity are connected through an adjustment channel with an adjustment knob. The distance between the tapered head on the adjustment knob and the oil hole is adjusted up and down to control the flow rate of the damping oil in the adjustment channel. Among them, the valve plate group covers both sides of the oil passage of the piston part. When the piston part is subjected to an excessive turning force, the damping oil in the oil passage flushes open the valve plate group downward or upward to the corresponding oil cavity to maintain stability.

[0011] Furthermore, the piston traction mechanism includes an axis, an oil seal seat for sealing the piston cavity, a seat cover covering the oil seal seat, and a main piston composed of a piston part and a valve plate group. The oil seal seat includes an inner oil seal ring and an outer sealing ring. The seat cover covers the oil seal seat at the port of the piston cavity. One end of the axis is an axis ring, and the other end sequentially penetrates the seat cover, the oil seal seat, and the main piston, and limits the main piston through a fixing part.

[0012] Furthermore, the piston part is provided with uniformly arranged oil passages. The valve plate group controls the opening or closing of the upper oil cavity and the lower oil cavity. The end face of the piston part is provided with a flower-shaped surface, which is pressed against the valve plate group. Among them, the two parts of the flower-shaped surface are designed to be relatively staggered.

[0013] Furthermore, the supplementary part is a cavity connecting the piston cavity. An air chamber base and a floating piston are provided in this cavity. The floating piston divides this cavity into an air cavity and a supplementary oil cavity. In this structure, both the air chamber base and the floating piston are adjusted through air holes and screws.

[0014] Furthermore, the adjustment channel is composed of an installation cavity, a branch channel 1, and a branch channel 2. The adjustment knob is spirally installed in the installation cavity. The adjustment knob is installed in the damper body through a pressure adjustment seat by a knob. Rotate the knob and the adjustment rod below the pressure adjustment seat to drive the adjustment screw to move up and down. The end of the adjustment screw is provided with a tapered head.

[0015] Furthermore, the external connection part is in the same axial direction as the axis ring. The axis ring is fixedly installed on the handlebar rotation device of a motorcycle or an electric vehicle. The external connection part is installed on the frame of the motorcycle or the electric vehicle.

[0016] The beneficial effects of the present utility model:

[0017] It is installed in the damper body through a pressure adjustment seat. Rotate the knob and the adjustment rod below the pressure adjustment seat to drive the adjustment screw to move up and down. The end of the adjustment screw is provided with a tapered head. When the adjustment screw moves to the uppermost end, the gap between the oil hole and the tapered head of the adjustment screw is the largest at this time, and the flow rate of the damping oil in the branch channel is the largest. When the adjustment screw moves to the lowermost end, the gap between the oil hole and the tapered head of the adjustment screw is the smallest at this time, and the flow rate of the damping oil in the branch channel is the smallest.

[0018] The valve plate group is called by both the upper and lower ends of the main piston. During movement, the axis moves up and down, driving the piston to move up and down. When the piston moves downward, the damping oil in the lower oil chamber flows into the upper oil chamber through the adjustment channel. Since the flow of the damping oil in the adjustment channel is unobstructed and the adjusted damping oil flow rate is fixed, when the vehicle encounters a sharp turn and the force applied by the main piston downward or upward is too large, the damping oil will flush through the oil passage of the main piston to open the valve plate group and flow into the lower oil chamber or flow into the upper oil chamber through the oil passage to open the valve plate group, thus ensuring the safety and stability of the damper.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] According to Figures 1-4 shown,

[0027] A steering damper for motorcycles and electric vehicles includes a damper body 100, and the damper body 100 is provided with a piston traction mechanism 1 that moves in a piston chamber 200, an external connection part 2 opposite to the piston traction mechanism 1, and a supplementary part 3 connected to the piston chamber 200;

[0028] The piston traction mechanism 1 divides the piston chamber 200 into an upper oil chamber S1 and a lower oil chamber S2 through a piston member 11 and a valve plate group 12. The upper oil chamber S1 and the lower oil chamber S2 are connected through an adjustment channel 5 with an adjustment knob 4. The distance between the taper head 41 of the adjustment knob 4 and the oil hole 300 is adjusted by rotating up and down to control the flow rate of the damping oil in the adjustment channel. Among them, the valve plate group 12 covers both sides of the oil passage 111 of the piston member 11. When the piston member 11 is subjected to an excessive steering force, the damping oil in the oil passage 111 flushes the valve plate group 12 downward or upward to the corresponding oil chamber to maintain stability.

[0029] The piston traction mechanism 1 includes a shaft center 101, an oil seal seat 102 for sealing the piston chamber 200, a seat cover 103 covering the oil seal seat 102, and a main piston composed of a piston member 11 and a valve plate group 12. Specifically, the oil seal seat 102 includes an inner oil seal ring and an outer sealing ring, and the seat cover 103 covers the oil seal seat 102 at the port of the piston chamber 200. One end of the shaft center 101 is a shaft ring, and the other end sequentially passes through the seat cover 103, the oil seal seat 102, and the main piston, and limits the main piston through a fixing part.

[0030] Specifically, the piston member 11 is provided with uniformly arranged oil passages 111. The valve plate group 12 controls the opening or closing of the upper oil chamber S1 and the lower oil chamber S2. The end face of the piston member 11 is provided with a flower-shaped surface 112, which is pressed against the valve plate group 12. Among them, the two parts of the flower-shaped surface 112 are designed to be relatively staggered. Through the staggered design, there is no conflict during the downward or upward process.

[0031] Specifically, the supplementary part 3 is a cavity connecting the piston chamber 200, and an air chamber base 31 and a floating piston 32 are provided in this cavity. Among them, the floating piston 32 divides this cavity into an air chamber 33 and a supplementary oil chamber 34. In this structure, both the air chamber base 31 and the floating piston 32 are adjusted through air holes and screws.

[0032] The adjustment channel 5 is composed of an installation cavity 51, a branch one and a branch two. The adjustment knob 4 is spirally installed in the installation cavity 51. Specifically, the adjustment knob 4 is installed in the damper body 100 by a knob 45 through a pressure adjustment seat 42. Rotate the knob 45 and the adjustment rod 43 below the pressure adjustment seat 42 to drive the adjustment screw 44 to move up and down. The end of the adjustment screw 44 is provided with a taper head 41. When the adjustment screw 44 moves to the uppermost end, the gap between the oil hole 300 and the taper head 41 of the adjustment screw 44 is the largest at this time, and the flow rate of the damping oil in the branch is the largest. When the adjustment screw 44 moves to the lowermost end, the gap between the oil hole 300 and the taper head 41 of the adjustment screw 44 is the smallest at this time, and the flow rate of the damping oil in the branch is the smallest.

[0033] Specifically, the external connection part 2 is in the same axial direction as the shaft ring. The shaft ring is fixedly installed on the handlebar rotation device of a motorcycle or an electric vehicle, and the external connection part 2 is installed on the frame of the motorcycle or the electric vehicle.

[0034] During operation, the main piston calls the valve plate group 12 at both the upper and lower ends. During movement, the center axis 101 moves up and down to drive the piston to move up and down. When the piston moves downward, the damping oil in the lower oil chamber S2 flows into the upper oil chamber S1 through the adjustment channel 5. Since the flow of the damping oil in the adjustment channel 5 is fixed during flow, when the vehicle makes a sharp turn and the force applied by the main piston downward or upward is too large, the damping oil will flush through the oil passage 111 of the main piston to open the valve plate group 12 and flow into the lower oil chamber S2 or flow into the upper oil chamber S1 through the oil passage 111 to open the valve plate group 12, thus ensuring the safety and stability of the damper.

[0035] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
