Abstract
The utility model discloses a kind of cylinder cap camshaft hole structures, comprising: seat under camshaft is arranged on cylinder cap；The camshaft seat of honour is arranged on cylinder head cover, and seat cooperation constitutes the mounting portion of cam under the camshaft seat of honour and camshaft；The end face of seat is higher than the end face at the camshaft seat of honour under camshaft, and the end face of seat constitutes the thrust surface of limit cam axis platform rank under camshaft；The side that seat is contacted with the camshaft seat of honour under camshaft is equipped with guide angle, and guide angle extends to thrust surface, has thrust and lubricating action.
Description
Technical field
The utility model belongs to technical field of automobile engine more particularly to a kind of cylinder cap camshaft hole structure.
Background technique
In the process of implementing the utility model, the inventor finds that the existing technology has at least the following problems: traditional technology
In, the camshaft hole of cylinder convering system does not have thrust and lubricating action.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of cylinder cap camshaft with thrust and lubricating action
Pore structure.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the utility model is a kind of cylinder cap camshaft hole knot
Structure, comprising:
Seat under camshaft is arranged on cylinder cap；
The camshaft seat of honour is arranged on cylinder head cover, and seat cooperation constitutes the peace of cam under the camshaft seat of honour and camshaft
Dress portion；
The end face of seat is higher than the end face at the camshaft seat of honour under the camshaft, and the end face of seat is constituted under the camshaft
The thrust surface of limit cam axis platform rank；
The side that seat is contacted with the camshaft seat of honour under the camshaft is equipped with guide angle, and the guide angle extends to described
Thrust surface.
The guide angle makes have gap between the thrust surface of seat and the end face at the camshaft seat of honour under the camshaft, lubrication
Oil is able to enter in the gap.
The guide angle extends up to the inner circle arc portion of seat under the camshaft, and the lubricating oil in guide angle is able to enter convex
Under wheel shaft in the inner circle arc portion of seat.
A technical solution in above-mentioned technical proposal has the following advantages that or beneficial effect, and there is thrust and lubrication to make
With.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the cylinder cap camshaft hole structure provided in the utility model embodiment；
Fig. 2 is the partial enlarged view of Fig. 1；
Label in above-mentioned figure is equal are as follows: 1, seat under camshaft, 2, guide angle, 3, thrust surface, 4, the camshaft seat of honour.
Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type embodiment is described in further detail.
Referring to Fig. 1-2, a kind of cylinder cap camshaft hole structure, comprising:
Seat under camshaft is arranged on cylinder cap；
The camshaft seat of honour is arranged on cylinder head cover, and seat cooperation constitutes the mounting portion of cam under the camshaft seat of honour and camshaft；
The end face of seat is higher than the end face at the camshaft seat of honour under camshaft, and the end face of seat constitutes limit cam axis platform under camshaft
The thrust surface of rank；
The side that seat is contacted with the camshaft seat of honour under camshaft is equipped with guide angle, and guide angle extends to thrust surface.Cam
Lubricating oil on axis can enter guide angle by thrust surface.
Guide angle makes have gap under camshaft between the thrust surface of seat and the end face at the camshaft seat of honour, and lubricating oil can be into
Enter in gap.To which lubricating oil being capable of camshaft lubrication hole.
Guide angle extends up to the inner circle arc portion of seat under camshaft, and the lubricating oil in guide angle is able to enter seat under camshaft
Inner circle arc portion in.
After above-mentioned structure, there is thrust and lubricating action.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as the various unsubstantialities carried out using the method concept and technical solution of the utility model change
Into, or it is not improved the conception and technical scheme of the utility model are directly applied into other occasions, in the utility model
Protection scope within.
