Problems solved by technology

[0005] In the above conventional shock absorber, there is a problem that during the compression stroke, the lower end of the buffer rubber is pushed into the gap between the piston rod and the cap member, causing interference with the piston rod, causing friction noise
[0006] In addition, there is a problem that foreign matter penetrates into the gap between the piston rod and the cap member, and the penetrated foreign matter is deposited on the oil seal provided on the upper part of the base case to cause oil leakage.

Embodiment Construction

[0027] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited or limited to the Examples. The same reference numerals suggest the same parts in the various figures.

[0028] figure 2 It is a perspective view showing main parts of the shock absorber of the present invention.

[0029] Such as figure 2 As shown, the cap member 20 of the present invention is attached to the upper end of the base shell 11 . Same as the prior art, a guide rod (not shown) for guiding the linear motion of the piston rod 13 and an oil seal (not shown) for sealing the working oil filled in the cylinder are provided on the upper part of the base shell 11 that constitutes the cylinder shape. out). Further, a buffer rubber 17 is adhered to an outer peripheral surface of the piston rod 13 passing through one end of the base housing 11 and exposed upward. Here, the buffer rubber 17 is normally in cont...

Abstract

Provided is a dust lip for a shock absorber, which is provided between a dust cover and a piston rod to prevent foreign substances from flowing into an oil sealing unit in twice and eliminate noise generated by mutual interference between a piston rod and a bumper rubber. The dust lip for the shock absorber includes: a piston rod; a base shell through which a part of the piston rod passes such that the piston rod is exposed to one side; a cap member covering one end of the base shell through which the piston rod passes; a bumper rubber attached to an outer periphery of the exposed portion of the piston rod; and a dust lip provided between the piston rod and the cap member to remove a gap between the piston rod and the cap member.

Description

technical field [0001] The present invention relates to a shock absorber, a shock absorber, used in a vehicle, and in particular, to a dust lip of a shock absorber formed between a dust cover and a piston rod to prevent Foreign matter enters the oil seal and eliminates the noise caused by the mutual interference between the piston rod and the buffer rubber. Background technique [0002] In existing vehicles, a variety of cushioning devices are used in order to improve the handling performance or driving feeling, especially between the wheels of the vehicle and the vehicle body, in order to absorb shock or impact, a cushioning device combined with a spring is used, Namely the shock absorber. [0003] Generally, a shock absorber is composed of a cylinder filled with working oil, a piston mounted on the end of a rod to reciprocate in the cylinder, and a valve provided on the piston. [0004] Such as figure 1 As shown, in the existing shock absorber, a piston rod 3 that penet...
