Problems solved by technology

[0004] In order to solve the problems existing in the automatic variable damping front shock absorber of motorcycles in the prior art, the compression and load of the shock absorbing spring, the stroke of the shock absorber and the cross-sectional area of ​​the piston to the maximum cross-sectional area of ​​the throttle hole and the rate of change of the cross-sectional area of ​​the throttle hole are not considered. In order to solve the problems such as the influence of road surface vibration, the present invention proposes a motorcycle front shock absorber with automatic variable damping

Embodiment 1

[0029] A pedal motorcycle, the design motorcycle and load weight W is 170kg, and the piston area F is 200mm 2 , The spring pressure and load T is 600N, and the piston stroke L is 60mm. Compared with the reference value of scooter motorcycles in the above table, the design values ​​of W and F are larger than the reference value, and the design value of L is smaller than the reference value. Positive number; if the design value of T is greater than the reference value, take a negative number; then:

[0030] = + =2.182+0.089 =2.415 (N·mm / kg)

[0031] = + =5.414+0.167 =5.554 (N·mm / kg)

[0032] = = 1.915 (mm 2 )

[0033] = = 0.883 (mm 2 )

[0034] = =0.0172 (mm 2 / mm).

Embodiment 2

[0036] An off-road vehicle motorcycle, the design motorcycle and load weight W is 310kg, and the piston area F is 500mm 2 1. The spring pressure and load T is 1300, and the piston stroke L is 200mm. Compared with the reference value of off-road motorcycles in the above table, the design values ​​of W and F are larger than the reference value, and take a positive number; the ratio of T and L design values If the base value is large, take a negative number; then:

[0037] = + =11.772+0.362 =12.076 (N·mm / kg)

[0038] = + =3.705+0.103 =3.891;

[0039] = =7.294 (mm 2 )

[0040] = =2.350 (mm 2 )

[0041] = =0.0247 (mm 2 / mm).

[0042] Obviously, the beneficial technical effect of the present invention is to accurately set the maximum cross-sectional area of ​​the throttle hole, the minimum cross-sectional area of ​​the throttle hole and the throttle The rate of change of the cross-sectional area of ​​the orifice ensures the comfort and safety of m...

Abstract

The invention provides an automatic variable damping front shock absorber of a motorcycle capable of vibrating along with ups and downs of a road surface to guarantee the comfort and the safety of motorcycle driving as much as possible and to accurately set the maximum cross sectional area and the cross sectional area change rate of a throttling groove of the automatic variable damping front shock absorber. The automatic variable damping front shock absorber comprises a base barrel, a fork pipe assembly, a damping spring, a positioning pipe, check valves, oil passing holes and a lower piston of the fork pipe assembly, a throttling hole is composed of a diameter-adjustable structure, and the maximum cross sectional area, the minimum cross sectional area and the cross sectional area change rate of the throttling groove are set according to the motorcycle, the loading weight, the solid load of the damping spring, the travel of the piston and the cross sectional area of the piston. The automatic variable damping front shock absorber has the advantages that the maximum cross sectional area and the cross sectional area change rate of the throttling groove of the automatic variable damping front shock absorber are accurately set, and the comfort and the safety of motorcycle driving are guaranteed to the maximum degree.

Description

[0001] technical field [0002] The invention relates to a motorcycle shock absorber technology, in particular to a motorcycle front shock absorber with automatically variable damping according to road surface vibration. Background technique [0003] In order to improve the comfort and safety of motorcycle riding, most motorcycles are equipped with front and rear shock absorbers to reduce the impact of vibration caused by uneven road surfaces on motorcycles and drivers. Most of the shock absorbers of prior art motorcycles adopt the damping mode of combining spring and hydraulic damping to absorb and consume the vibration energy during the running of the motorcycle. The so-called damping method of combining spring and hydraulic damping means that the shock absorber is equipped with both a damping spring and a hydraulic damping mechanism. The damping spring is mainly used to resist the vibration caused by inertial gravity, and the hydraulic damping mechanism is mainly used It...
