Abstract
The utility model relates to a rocker arm assembly, which comprises two rocker arm heads. The rocker arm heads are respectively arranged on two sides of a shaft sleeve, a circular abrasion resistant head is arranged on each rocker arm head, and threads are arranged on the abrasion resistant heads and fixed with threads on the rocker arm heads by means of screwing. The rocker arm assembly has the advantages of simple forming, lower cost and small condemnation factor due to the fact that traditional square press-in type abrasion resistant heads are modified into the circular threaded abrasion resistant heads, structurally simplified support structure and capabilities of reliably guaranteeing power performance and simultaneously having certain superiorities in aspects of service life, part stability and easy installation and maintenance.
Description
Technical field
The utility model relates to a kind of engine fittings, relates in particular to a kind of Rocker arm assembly.
Background technique
The pitman arm shaft assembly is as a kind of accessory of motor, offers rocker shaft hole and be used for by the bolt hole of bolton on engine cylinder on structure is formed.But the wear-resisting head structure of existing a lot of Rocker arm assemblies mostly is the square part combination, and be pressed into by mould, wherein exist a lot of defectives, as consuming bigger cost aspect the processing, having higher scrappage aspect the utilization, causing mould to damage easily installing.
The model utility content
At above defective, the utility model provides a kind of supporting structure, cost is lower, scrappage is little Rocker arm assembly simplified, to solve like product in the defective aspect working life, part stability and the installation and maintenance.
For achieving the above object, the utility model is by the following technical solutions:
A kind of Rocker arm assembly comprises two rocker heads, and the axle sleeve both sides are respectively equipped with a rocker head, and described rocker head is provided with circular wear-resisting head; Described wear-resisting head is provided with screw thread and is tightened with the rocker head screw thread.
The beneficial effect of Rocker arm assembly described in the utility model is: traditional square forced wear-resisting head is improved to round thread formula wear-resisting head, makes that its moulding is simple, cost is lower, scrappage is little; Structurally simplified supporting structure, when reliably guaranteeing power performance, in working life, part stability and be easy to have certain advantage aspect the installation and maintenance.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the Facad structure schematic representation of the described Rocker arm assembly of the utility model embodiment.
Among the figure:
1, rocker head; 2, wear-resisting head; 3, axle sleeve; 4, fixing bolt; 5, pitman arm shaft.
Embodiment
As shown in Figure 1, the described Rocker arm assembly of the utility model embodiment, comprise rocker head 1 and axle sleeve 3, penetrate pitman arm shaft 5 in the axis hole of axle sleeve 3, engine cylinder is fixed in by fixing bolt 4 and the while in axle sleeve 3 middle parts, described axle sleeve 3 both wings positions all are provided with rocker head 1, and described rocker head 1 is provided with circular wear-resisting head 2, and this wear-resisting head 2 is provided with screw thread and is tightened with rocker head 1 screw thread.
Above embodiment is more preferably embodiment a kind of of the utility model, and the common variation that those skilled in the art carry out in the technical program scope and replacing should be included in the protection domain of the present utility model.
