The body rate of wear, further to extend the service life.
In above-mentioned knuckle, the annular seal is distributed there are two and along the axially spaced-apart of pin hole, two annulars
The annular oil storage tank for storing lubricant grease is formed between sealing.Using above-mentioned design, further to delay ring-shaped rubber
Body abrasion, Lai Yanchang service life.
In above-mentioned knuckle, the annular seal is triangular in shape in the upward section of pin bore axis.
In above-mentioned knuckle, the oil reservoir with a thickness of 0.1mm.
Compared with prior art, this knuckle is covered with one layer of oil reservoir for having lubricant effect by applying on the inside of bushing, and
Annular oil seal by the way that two sides are arranged in effectively, adequately protect to oil reservoir, effectively to extend the lubrication time of oil reservoir, from
And slow down the abrasion between pin shaft and bushing, the service life of Lai Yanchang knuckle.
