0.014D~0.016D, it is easy to bulb pin cap radial rotating, ensures the bulb of ball stud and bulb pin cap, ball cup is good connects
Performance is touched, improves the steering precision of tractor.Structure of the grease fitting mounted in screw lid upper end is easy to grease up, lubricates
Fat is injected in bulb pair through stage clip, improves the lubricant effect of the secondary each contact part of bulb.On dirt-proof boot of the present utility model
End is fixed on rod head by clamp ring, and it is new to improve this practicality by sealing lip ball sealer head pin for dirt-proof boot lower end
The dust-proof effect of type, prevent each part premature abrasion failure that bulb is secondary.
The advantages of the utility model and feature, diagram reconciliation will be carried out by the non-limitative illustration of preferred embodiment below
Release, these embodiments, only provide as an example referring to the drawings.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in figure 1, the utility model includes pull bar 1, ball stud 2, grease fitting 3 and dust-proof mechanism 4, ball stud 2
