Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0011] Such as figure 1 Shown is a shock absorber that can eliminate the shock absorbing oil foam, including the oil storage tank 1, the working cylinder 2 in the oil storage tank 1, the piston rod 3 in the working cylinder 2 and the piston rod 3 connected Piston 4 5, a defoaming spring 6 is fixedly sleeved on the outer wall of the working cylinder 2 .

[0012] When the shock absorber piston 4 moves up and down, the shock absorber oil 5 circulates in the oil storage tube 1 and the working cylinder 2 in the direction of the arrow in the figure, and the shock absorber oil 5 is generated in the oil storage tube 1 during the flow process. A large number of damping oil foams, these foams move with the flow of the damping oil, when these foams meet the defoaming spring 6 fixedly set on the outer wall of the working cylinder 2 during the movement, the foams b...

Abstract

The invention discloses a damper capable of eliminating damping oil foam. The damper comprises an oil storage barrel, a work cylinder arranged in the oil storage barrel, a piston rod in the work cylinder and a piston connected on the piston rod. A foam eliminating spring is fixedly sleeved on the outer wall of the work cylinder, the foam eliminating spring can scrape foam in damping oil away, the damping oil foam is prevented from entering the work cylinder, idle running and distorsion in a work process of the damper are eliminated, abnormal sound in a running process of the damper is removed, and vehicle comfortableness and vehicle stability are improved.

Description

technical field [0001] The invention relates to the field of vehicle shock absorbers, in particular to a shock absorber capable of eliminating the foam of shock absorbing oil in the working cylinder of the shock absorber. Background technique [0002] When the vehicle is running, the piston rod of the shock absorber continuously performs telescopic movement in the working cylinder, and the damping oil in the working cylinder generates a damping force through the resistance valve system to buffer the impact force and reduce the vibration during the driving process of the vehicle . During the working process of the shock absorber, the shock absorber oil is continuously pressed into the oil storage tank and then flows into the working cylinder. When the shock absorber oil is flowing at high speed, high pressure and frequently, the temperature of the shock absorber oil continues to rise, and the shock absorber oil emulsifies to produce foam , resulting in an increase in the vol...
