It is that lug boss 21,22 is made up of synthetic material, synthetic material is, for example, polyamide 6 .6 (PA) or polyether-ether-ketone (PEEK).
As shown in Figure 4 and Figure 5, lug boss 21,22 is overmolded on the base portion 13 and flange 14,15 of the metal.It is convex
Edge 14,15 includes pass through openings 14a, 15a, and the material of lug boss 21,22 is molded in the pass through openings to ensure to assemble
The strength of good supportive body 4 is fixed.Lug boss 21,22 is molded during same processing step by identical material, and is passed through
The coupling part 23 of base portion 13 is taken shape in link together.Selected as one kind, lug boss 21,22 can be separately formed.
(not shown) is selected as one kind, lug boss 21,22 with base portion 13 and flange 14,15 is made by belonging to same
, be made up and the single metal plate deformed of punching press.
Lug boss 21,22 each includes the first longitudinal direction holding meanss 24,25 coordinated with tappet body 7.It is described to keep dress
24, the 25 laterally outwardly flanges 26,27 for each including extending laterally towards tappet body 7 from the lug boss 21,22 are put, and
The holding meanss 24,25 are provided with lower support surface.
The hole 10b of tappet body 7 includes inwardly projecting portion 28,29, and the inwardly projecting portion is endured from hole 10b directions
The inner transverse extension of bar main body 7, and each there is the top edge 30,31 with upper support surface.Hole 10b ledge
28th, 29 is relative to each other relative to axis X 2, and the position of ledge 28,29 and the position of the lug boss 21,22 of supportive body 4
Put corresponding.The upper support surface of inwardly projecting portion 28,29 supports the lower support table of laterally outwardly flange 26,27 in the vertical
Face.
Advantageously, it is provided between laterally outwardly flange 26,27 and associated ledge 28,29 between axial direction
Gap.
Advantageously, the ledge 28,29 each includes being exclusively used in the respective shapes with laterally outwardly flange 26,27
Surface engagement fi-ustoconical surface.More precisely, formed by the fi-ustoconical surface of the ledge 28,29
Conical tip centered on central axis X 2 and point to roller 6, i.e. the circular cone is along the insertion with rolling assembly 3 in tappet 2
Point in direction identical direction.The fi-ustoconical surface being engaged of part 26,27 and 28,29 respectively along with by the support
Main body 4 from tappet body 7 remove displacement conversely to direction point to.Supportive body 4 is substantially improved in tappet body 7
Axially retain.
Lug boss 21,22 also each include with the lower surface of laterally outwardly flange 26,27 it is longitudinally opposed to chamfered portion
32、33.The chamfered portion 32,33 of lug boss 21,22 is exclusively used in and the respective ramp part of inwardly projecting portion 28,29 34,35
Coordinate, to be convenient to make lug boss 21,22 to be slidably inserted into tappet body 7, more particularly, by inwardly projecting portion 28,
29 and insert in tappet body 7.
Rolling assembly 3 is inserted longitudinally into cavity volume 11 by the lower edge 9 from the tappet body 7 towards top edge 8.It is raised
Portion 21,22 is arranged on the chamfered portion 34 of the inwardly projecting portion 28,29 in the hole 10b of tappet body 7,35 elastic deformations.
Lug boss 21,22 slides against the inwardly projecting portion 28,29, until the laterally outwardly flange 26,27 of lug boss 21,22 is logical
Untill the edge 30,31 for crossing the part 28,29.Lateral flange 26,27 is supported by the edge 30,31 in the vertical.Then
The rolling assembly 3 for including the supportive body 4 of supporting pin 5 in the vertical and roller 6 is configured in the cavity volume of cylindrical tappet body 7
In 11, and it is maintained at by means of the lug boss 21,22 in the tappet body.
Tappet body 7 also includes being used for the second longitudinal direction holding meanss 36,37 being maintained at rolling assembly 3 in tappet 2.The
Two longitudinal holding meanss are each included from the lateral part that the top edge 8 of tappet body 7 extends towards the inner side of tappet body 7
36、37.Lateral part 36,37 is relative to each other towards axis X 2.
The lateral part 36,37 covers the end 18,19 of pin 5 in the vertical, so as to be able to prevent the pin 5 by from very
Any dismounting (dismounting) of the upside of bar main body 7, therefore rolling assembly 3 is prevented by from the upside of tappet body 7
Any dismounting.
First fixing device 24,25 of the lug boss 21,22 that then rolling assembly 3 passes through supportive body 4 in side is with enduring
Between the inwardly projecting portion 28,29 of bar main body 7 cooperation come longitudinally keep and in opposite side by tappet body 7 second
Fixing device 36,37 is longitudinally kept.
The difference of second embodiment and Fig. 1 to Fig. 4 embodiment shown in Fig. 5 to Fig. 7 is, first longitudinal direction holding meanss
24th, 25 also include the swells (bulge) 38,39 with the cooperation of the inwardly projecting portion 28,29 of tappet body 7.
Swells 38,39 is laterally projecting from lug boss 21,22 towards tappet body 7 respectively.Advantageously, swells 38,
39 can have hemispherical shape as shown in Figure 6 or frusto-conical as shown in Figure 7, to be easily inserted tappet master
In the hole 10b of body 7 inwardly projecting portion 28,29.When supportive body 4 is inserted in the cavity volume 11 of the tappet body 7, institute
Swells 38,39 is stated to slide against the chamfered portion 34,35 of the inwardly projecting portion 28,29.
Inwardly projecting portion 28,29 is each respectively arranged with recess 40,41.Swells 38,39 be entrenched in the recess 40,
In 41 and it ensure that longitudinal direction of the improved supportive body 4 in tappet body 7 is kept.In fact, the supportive body 4 is by two
Kept on individual longitudinal direction, and prevent any relative rotation between the supportive body 4 and tappet body 7.
As an alternate embodiment (not shown), lug boss 21,22 can only include the swells 38,39 and be used as the
One longitudinal holding meanss 24,25.
