Problems solved by technology

The preload is related to the preset optimal load. The greater the optimal load, the greater the preload of the spring. When the actual load is much greater than the optimal load, the shock absorption stroke of the shock absorber will not be enough, which will affect the comfort performance, and when the actual load is far less than the optimal load, the damping range of the shock absorber is small (expressed as hard), which affects the comfort
[0003] However, in actual use, two-wheel vehicles, tricycles, four-wheel vehicles and other means of transportation generally have the problem of large load changes. Sometimes they carry 1 person, sometimes 2 people, sometimes 5 people, sometimes cargo, minimum load and maximum load It is not fixed, the difference is large, and it is impossible to accurately select the appropriate preload
[0004] For this reason, the general way in the prior art is to select the shock-absorbing spring that the coefficient of elasticity is big for use, sacrifice comfort.

Embodiment 1

[0024] A shock absorber with the function of intelligently and automatically adjusting the preload, comprising a damping rod composed of a first telescopic part 5 and a second telescopic part, the first telescopic part 5 is a piston cylinder, the second telescopic part is a piston rod, and the damping rod Upper cover damping spring 8, one end of damping spring 8 is space-limited with the limit structure on the first telescopic part 5, and the other end of shock-damping spring 8 is space-limited with the position-limiting structure on the second telescopic part. The limit structure on the telescopic part 5 is the lifting seat 9, which can be lifted up and down with the first telescopic part 5, and the first telescopic part 5 of the damping rod has an adjusting thread and an adjustment screw sleeved on the telescopic part. The adjusting gear 7 fitted with thread, the adjusting gear 7 drives the lifting seat 9 to go up and down, adjusts the pre-pressure of the shock absorbing spri...

Embodiment 2

[0038] Compared with Embodiment 1, the first driven gear 17 and the third driven gear 19 have a one-way clutch mechanism inside, so that the first driven gear 17 and the third driven gear 19 only move up and down on the main rack 1. Reverse rotational movements can be output to the reversing gears 22, respectively. The three step surfaces on the gear plate 2 are set from high to low, and the height of the upshift position 2-0 is the highest, so as to ensure that the correct shift lever 24 is correctly shifted.

Embodiment 3

[0040] Such as figure 1 , 2 , 3, 4, and 5, compared with Embodiment 1, the contact surface between the toggle switch 27 and the fixed seat 25 has a rough surface that can provide a certain friction force to overcome the reset force of the switch spring 26. In the toggle switch The head of 27 is provided with retractable pointer 28, is provided with the pointer spring that is used for telescopic reset between pointer 28 and shift switch 27, has drag shift shift switch 27 to compress on the contact surface of pointer 28 and gear plate 2 Or break away from the rough surface of the fixing seat 25, the elastic force of the switch spring is greater than the elastic force of the pointer spring.

[0041] This scheme can reduce the shifting frequency of the shift paddle 24 .

[0042] When the shock absorber rises, the main rack 1 drives the gear plate 2 to rise together, and the gear plate 2 will squeeze the shift switch 27 when it moves upward, causing the shift switch 27 to move le...

Abstract

The invention relates to a shock absorber with the intelligent automatic pre-pressure adjusting function. The shock absorber comprises a damping rod and a damping spring. A first telescopic portion of the damping rod is provided with a lifting seat and an adjusting gear. The adjusting gear drives the lifting seat to rise and fall to adjust the pre-pressure of the damping spring. An adjusting device comprises a main rack, a gear plate, a gear shifting mechanism and a gear shifting transmission mechanism. The gear shifting transmission mechanism is provided with three gears, namely the forward gear for driving the adjusting gear to fall, the neutral gear not driving the adjusting gear and the reverse gear for driving the adjusting gear to rise. The gear shifting transmission mechanism is located in different gears through gear shifting motion of a gear shifting driving lever, and when a gear shifting switch is located in the upshift position, the gear shifting transmission mechanism is in the reverse gear state; when the gear shifting switch is located in the downshift position, the gear shifting switch drives the gear shifting driving lever to make the gear shifting transmission mechanism located in the forward gear state. The shock absorber has the advantages that the pre-pressure can be automatically adjusted according to loads, and the comfort requirements under different load conditions are met.

Description

technical field [0001] The invention relates to a shock absorber with the function of intelligent automatic adjustment of pre-pressure. Background technique [0002] Shock absorbers are widely used in vehicles because they can quickly attenuate the impact and vibration caused by changes in vehicle speed, load and various road conditions. The comfort of the shock absorber is directly related to the elastic coefficient and preload of the shock absorber. Under the same shock absorbing stroke, the greater the elastic coefficient of the shock absorber (expressed as harder), the better the comfort. Poor, the greater the difference between the maximum load and the minimum load that can be tolerated; the smaller the elastic coefficient of the shock absorber spring, the better the comfort, but the smaller the difference between the maximum load and the minimum load that can be tolerated. The preload is related to the preset optimal load. The greater the optimal load, the greater the...
