Problems solved by technology

Obviously, the prior art motorcycle front shock absorber cannot meet the above-mentioned requirements, and the damping force of the shock absorber cannot be automatically adjusted with the vibration force that the motorcycle is subjected to, so its damping effect is limited, which directly affects the driving experience of the motorcycle. Comfort and Safety
[0003] In order to solve the problem that the damping force of the front shock absorber of the motorcycle cannot be automatically adjusted according to the vibration force received by the motorcycle, a kind of throttle hole is not provided on the positioning tube, but a variable diameter structure is used to form the throttle hole, that is, The outer diameter of the positioning tube gradually decreases from the upper end of the oil hole to the upper part of the positioning tube, so that the size of the orifice formed by the outer circle of the positioning tube and the inner circle of the lower piston of the fork tube assembly changes along the axial direction of the positioning tube

specific Embodiment 1

[0020] A certain type of motorcycle has a self-weight of about 110kg and can accommodate 2 people. At this time, the motorcycle and its load weigh about 250kg, and it is mainly driven on urban roads. The maximum cross-sectional area of ​​the throttle groove is 15.5mm 2 , the change rate of the cross-sectional area of ​​the throttle groove is 0.1345mm 2 / mm. When the shock absorber piston moves 30mm before the motorcycle is shaken, the cross-sectional area of ​​the throttle hole is 11.465mm 2 , the return velocity of the hydraulic oil in the hydraulic damping chamber is relatively large, that is, the damping force is small, and the shock absorbing spring will reset quickly; when the shock absorber piston moves 60mm before the motorcycle is shaken, the cross-sectional area of ​​the orifice 7.430mm 2 , the return velocity of the hydraulic oil in the hydraulic damping chamber is small, that is, the damping force is large, and the shock spring will reset slowly; when the shock a...

specific Embodiment 2

[0021] A certain type of motorcycle has a self-weight of about 200kg and can accommodate 2 people. At this time, the weight of the motorcycle and its load is about 340kg, and it is mainly driven on rural roads. The maximum cross-sectional area of ​​the throttle groove is 14.2mm 2 , the change rate of the cross-sectional area of ​​the throttle groove is 0.1355mm 2 / mm. When the shock absorber piston moves 30mm before the motorcycle is shaken, the cross-sectional area of ​​the throttle hole is 10.135mm 2 , the return velocity of the hydraulic oil in the hydraulic damping chamber is relatively large, that is, the damping force is small, and the shock absorbing spring will reset quickly; when the shock absorber piston moves 60mm before the motorcycle is shaken, the cross-sectional area of ​​the orifice 6.070mm 2 , the return velocity of the hydraulic oil in the hydraulic damping chamber is small, that is, the damping force is large, and the shock spring will reset slowly; when ...

Abstract

The invention provides a motorcycle automatic damping-changing front shock absorber damper for ensuring the comfortability and security of motorcycle driving as far as possible, and setting the maximum cross-sectional area of a throttling groove of the damping-changing front shock absorber damper and the cross-sectional area variable rate of the throttling groove precisely. The motorcycle automatic damping-changing front shock absorber damper provided by the invention comprises a bottom barrel, a forked pipe assembly, a damping spring, a locating pipe, a one-way valve, an oil through hole anda lower piston of the forked pipe assembly, wherein a throttling hole is of a reducing structure, and the cross-sectional area of the throttling hole and the cross-sectional area variable rate of thethrottling hole are set according to the weight of a motorcycle and load. The motorcycle automatic damping-changing front shock absorber damper provided by the invention has the beneficial technical effects that the maximum cross-sectional area of the throttling groove of the motorcycle automatic damping-changing rear shock absorber and the cross-sectional area variable rate of the throttling groove are set precisely, and the comfortability and the security of the motorcycle driving is ensured to the greatest extent.

Description

technical field [0001] The invention relates to a motorcycle shock absorber damper, in particular to a motorcycle automatic variable damping front shock absorber damper. Background technique [0002] With the development of motorcycle technology, the requirements for the comfort and safety of motorcycle driving are getting higher and higher. At present, most motorcycles are equipped with front and rear shock absorbers to reduce the impact of vibrations caused by uneven road surfaces on motorcycles and drivers. Most of the shock absorbers in the prior art motorcycles adopt the combination of spring and hydraulic damping to absorb and consume the vibration energy during the running of the motorcycle, so as to reduce the impact of vibration on the motorcycle and the drivers and passengers. The basic working principle of the motorcycle shock absorber is: when the motorcycle is running, if it encounters a raised ground, the front wheel of the motorcycle compresses the shock abso...
