Abstract
Provided is a cylinder cover with a thermostat installing hole. The cylinder cover with the thermostat installing hole is used for engine assembling. An air inlet side and an air outlet side are arranged on two sides of a cylinder cover, a thermostat installing hole which is close to the air outlet side is installed on the top surface of the cylinder cover in a casting mode, the thermostat installing hole is communicated with a water jacket of the cylinder cover, installing bolt holes are arranged on the periphery of the thermostat installing hole in a symmetrical mode, a bottom hole of the thermostat installing hole is provided with a water inlet in a casting mode, a main through hole is installed on the bottom surface of the thermostat installing hole in a casting mode, a side through hole is arranged on the position of the air outlet side direction in a casting mode, the main through hole and the side through hole are respectively communicated with the water inlet. Due to the fact an integrated thermostat installing hole design is used by the cylinder cover with the thermostat installing hole, the thermostat is directly installed on the top surface of the cylinder cover, the structure is simple, the whole engine is compact, material cost is saved, the whole thermostat is integrated with the cylinder cover, and reliability is greatly improved.
Description
Technical field
The utility model relates to the Manufacturing Technology for Automotive Parts field, specifically a kind of cylinder cap with the thermostat mounting hole.
Background technique
Present engine generally adopts the cooling liquid forced circulation system to guarantee that motor works under more stable temperature, and the groundwork principle is to utilize vehicle water pump to improve the pressure of cooling liquid, it is done in whole engine system circulate.
The cooling water circulation of motor has two closed loops: major cycle and short circle.Major cycle refers to: open the limit value (for example 88 ℃) of setting when engine coolant is elevated to thermostat, the main valve of thermostat is all opened, the auxiliary-valve Close All, and cooling liquid flows through radiator by thermostat lowers the temperature, and gets back at last water pump.Short circle refers to: when engine coolant temperature does not also reach the limit value of thermostat unlatching setting, and the main valve Close All of thermostat, auxiliary-valve is all opened, and cooling liquid is got back to water pump at last by the water jacket of cylinder body and the water jacket absorbing heat of cylinder cap.Realizing that greatly in the selection of short circle and the temperature control, thermostat plays vital effect.
Present thermostat mostly is greatly the thermostat of monolithic construction, is divided into mechanical type and electronic type.Although the thermostat structure of monolithic construction can satisfy the functional requirement of thermostat, there is following drawback.
1, the motor complete machine size of independent installation thermostat is larger.Most of independent thermostat of installing all is the both sides at motor, and need to could practical function by exterior part, thereby causes complete machine wider.If be installed in both ends of the surface, cause complete machine oversize.
2, the overall cost of motor of independent installation thermostat is relatively high.Because the independent thermostat of installing must be realized by outside transition piece, so just needs to increase extra cost; Secondly in installation process, must carry out secondary installing, namely at first transition piece is installed on the cylinder body, again thermostat is installed on the transition piece, cause the increase of assembling set; Thereby whole motor cost is high.
3, the independent weak point in working life that thermostat is installed.Owing to adopting secondary installing, in use, particularly in the bad situation of working condition, when engine vibration is larger, the problem such as cause that construction bolt comes off easily.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of cylinder cap with the thermostat mounting hole, to realize improving the motor operational reliability, reduces the purpose of product cost.
For achieving the above object, the both sides of cylinder cap of the present utility model are distributed with air inlet side and exhaust side; Be cast with the thermostat mounting hole on the end face of cylinder cap, near the exhaust side, thermostat mounting hole and cylinder cover water jacket connect, be symmetrically distributed with the construction bolt hole around the thermostat mounting hole, the bottom orifice of thermostat mounting hole is cast with the water inlet, the place, bottom surface of thermostat mounting hole is cast with main through hole, the exhaust side surface direction place of thermostat mounting hole is cast with by-pass hole, main through hole, by-pass hole respectively with the water inlet with communicate.
The utility model compared with prior art has following advantage.
1, owing to adopt the design of integrated form thermostat mounting hole, do not need to design complicated exterior line again and be connected with transition, directly install at the end face of cylinder cap, simple in structure, the motor complete machine is compact.
2, directly thermostat is installed on the top surface of cylinder cover, the thermostat mounting hole of cylinder cap just is equivalent to the shell of thermostat, thereby can the economical with materials cost; In addition, owing to adopt direct-connected mode, the transition piece in the middle of not needing also can reduce cost.
3, thermostat directly utilizes bolt to be fixed connection with cylinder cap, and whole thermostat is connected as a single entity with cylinder cap, and reliability improves.
Description of drawings
Fig. 1 is top surface structure schematic representation of the present utility model.
Fig. 2 is the K-K sectional view of Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, be distributed with air inlet side 1 and exhaust side 2 in the both sides of cylinder cap; On the end face 3 of cylinder cap, near exhaust side 2, be cast with thermostat mounting hole 4, thermostat mounting hole 4 directly connects with cylinder cover water jacket by cast inside, around thermostat mounting hole 4, be symmetrically distributed with three construction bolt holes 5, be used for installing thermostat, bottom orifice at thermostat mounting hole 4 is cast with water inlet 6, place, bottom surface at thermostat mounting hole 4 is cast with main through hole 7, exhaust side surface direction place at thermostat mounting hole 4 is cast with by-pass hole 8, main through hole 7, by-pass hole 8 respectively with water inlet 6 with communicate.
The short circle process is during the utility model work: the water in the water jacket enters water inlet 6 by the water jacket that communicates with thermostat mounting hole 4, control the main valve Close All by the valve on the thermostat, auxiliary-valve is all opened, and makes all cooling waters flow back to water pump by by-pass hole 8.
The major cycle process is during the utility model work: the water in the water jacket enters water inlet 6 by the water jacket that communicates with thermostat mounting hole 4, controlling main valve by the valve on the thermostat all opens, the auxiliary-valve Close All, allow all cooling waters flow to external heat sink by main through hole 7 and cool off, then flow back to water pump.
