According to the cylinder cover with the hydraulic tappet hole supporting structure, the structural strength and the rigidity of the cylinder cover are improved, the casting process and the machining process of the cylinder cover are improved and the actual operation process of a motor is more reliable.
Description
Technical field
The utility model relates to vehicle motor component technical field, refers to particularly a kind of cylinder head with hydraulic tappet hole supporting structure.
Background technique
At present, the motor of exploitation generally adopts single cylinder four valves, Dual Over Head Camshaft cylinder head and hydraulic rocker tappet timing system both at home and abroad; This type of cylinder head hydraulic tappet needs high-pressure oil duct that oil pressure is provided, generally hydraulic tappet hole boss is directly arranged on high-pressure oil duct, hydraulic tappet turns round with high engine speeds, hydraulic tappet active force repeated action is on horizontal oil duct, hydraulic tappet hole supporting structure is owing to being subject to periodic lateral forces, more easily produce stress deformation, this has proposed requirement to the intensity of hydraulic tappet hole supporting structure and reliability; And if tappet hole boss strength deficiency, machine adds in the process of cylinder head tappet hole and easily produces stress deformation herein, causes machine to add reject rate and rises, and expends a large amount of manpower and materials.
Summary of the invention
The purpose of this utility model is exactly the deficiency that will solve above-mentioned background technology, and a kind of cylinder head with hydraulic tappet hole supporting structure is provided, to improve the structural strength of cylinder cap.
The technical solution of the utility model is: a kind of cylinder head with hydraulic tappet hole supporting structure, it comprises two horizontal oil ducts that are set in parallel in cylinder head as hydraulic tappet and camshaft fuel feeding, described horizontal oil duct inner side is communicated with a plurality of hydraulic tappet hole boss, in described hydraulic tappet hole boss, hydraulic tappet hole is installed, in described hydraulic tappet hole, hydraulic tappet is installed, it is characterized in that: in described cylinder head, be also provided with spark-plug hole boss, described spark-plug hole boss is arranged on horizontal oil duct top, spark-plug hole boss is provided with gap with horizontal oil duct, described hydraulic tappet hole boss is connected in the radial outer wall of spark-plug hole boss, between described horizontal oil duct, be provided with reinforcement gusset, described horizontal oil duct, hydraulic tappet hole boss and spark-plug hole boss link into an integrated entity by strengthening gusset.
In such scheme:
Four of described hydraulic tappet hole boss are one group, are evenly distributed on the radial outer wall surrounding of spark-plug hole boss.
Described hydraulic tappet hole boss is connected by chamfering transition with the radial outer wall of spark-plug hole boss.
On described strong gusset, offer a plurality of lightening holes.
Described lightening hole is waist typed through hole.
The utility model can improve structural strength and the rigidity of cylinder head, and has improved casting technique and the mechanical processing technique of cylinder head, and the actual moving process of motor is also more reliable.
Accompanying drawing explanation
Fig. 1 is structure schematic top plan view of the present utility model;
Fig. 2 is structural upright schematic diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 1, a kind of cylinder head with hydraulic tappet hole supporting structure shown in Fig. 2, it comprises two horizontal oil ducts 7 that are set in parallel in cylinder head 2 as hydraulic tappet and camshaft fuel feeding, laterally oil duct 7 inner sides are communicated with a plurality of hydraulic tappet hole boss 8, hydraulic tappet hole 3 is installed in hydraulic tappet hole boss 8, in hydraulic tappet hole 3, hydraulic tappet is installed, it is characterized in that: in cylinder head 2, be also provided with spark-plug hole boss 1, spark-plug hole boss 1 is arranged on horizontal oil duct 7 tops, spark-plug hole boss 1 is provided with gap with horizontal oil duct 7, hydraulic tappet hole boss 8 is connected in the radial outer wall of spark-plug hole boss 1, laterally between oil duct 7, be provided with and strengthen gusset 4, laterally oil duct 7, hydraulic tappet hole boss 8 and spark-plug hole boss 1 link into an integrated entity by strengthening gusset 4.
When engine operation, produce periodic lateral force time, strengthen gusset 4 and spark-plug hole boss 1 and can there is supporting effect to hydraulic tappet hole boss 8, being hydraulic tappet hole boss 8 can the periodicity lateral force of negative function on hydraulic tappet hole boss 8 by strengthening gusset 4 and spark-plug hole boss 1, to improve the intensity of hydraulic tappet hole boss 8, prevent that hydraulic tappet hole boss 8 from deforming, bulk strength and the rigidity of cylinder cap is provided accordingly.
In the present embodiment:
8 four of hydraulic tappet hole boss are one group, are evenly distributed on the radial outer wall surrounding of spark-plug hole boss 1.Hydraulic tappet hole boss 8 is connected by chamfering 6 transition with the radial outer wall of spark-plug hole boss 1.
Exist in addition, on strong gusset 4, offer a plurality of lightening holes 5, lightening hole 5 is waist typed through hole.To improve casting manufacturability and to reach the object of loss of weight.
