The thermostat base is more compact and reasonable in structure, water temperature signals of the whole instruments, an ECU unit and an EGR unit are integrated on the thermostat base to be together collected, and the thermostat base adopts a full-space-utilizing design according to the designed space structure of a diesel engine, so the complete size of the diesel engine can be basically kept unchanged due to the technical scheme.
Description
Technical field
The utility model belongs to engine component, is specifically related to a kind of thermostat base device of use for diesel engine.
Background technique
Along with the increasingly stringent of national environmental protection rules, the dual fuel of diesel engine standard is also more and more stricter.Much diesel engine producer adopts the multiple technologies measure to control toxic emission at present, and a lot of important parts all adopt electronic control.ECU(finished vehicle electronic control system for example) control unit need to provide water temperature signal, with associated components, carries out corresponding control operation; In cooling system for recycled exhaust gas, also need to provide water temperature signal to control the size that the EGR valve is opened to its corresponding control unit.At present the collection of a lot of diesel engine water temperature signals, all be selected in thermostat base, thermostat housing or other relevant position usually, so just makes signal acquisition point more messy and be not easy to the wire harness reasonable Arrangement.The utility model will propose a kind of thermostat base that more rationally gathers water temperature signal, make above-mentioned technological deficiency be improved significantly.
Summary of the invention
The purpose of this utility model is to provide a kind of and will gather car load instrument, ECU unit and EGR(gas recirculation system) three thermostat bases that the control unit water temperature signal is integrated in one.
Below in conjunction with accompanying drawing, principle of the present utility model and structure are described.
Many interfaces thermostat base, comprise thermostat base, thermostat housing, heater switch device, ECU cooling-water temperature sensor, EGR cooling-water temperature sensor, instrument cooling-water temperature sensor and sebific duct etc.Its technological scheme is: thermostat base top is connected by flange with thermostat housing; With the thermostat base upper flange, be 45 ° and be provided with the heater switch device; The left side of thermostat base is provided with the ECU cooling-water temperature sensor; The right side of thermostat base is provided with the EGR cooling-water temperature sensor; The below of ECU cooling-water temperature sensor is provided with the instrument cooling-water temperature sensor; The EGR(control unit) below of cooling-water temperature sensor is provided with the water feeding of water pump adapter, and water feeding of water pump is connected to sebific duct.In thermostat base, heater switch device interface center line and EGR cooling-water temperature sensor interface center line are 45 ° and cross.
Thermostat base except be provided with engine body and thermostat housing junction surface, also being provided with 5 main interfaces, i.e. heater switch device interface, ECU cooling-water temperature sensor interface, EGR(control unit) cooling-water temperature sensor interface, instrument cooling-water temperature sensor interface and water pump take over interface.The warm-air drier interface is located at the side of thermostat base flange, and ECU cooling-water temperature sensor interface is mutually corresponding with the left and right side that EGR cooling-water temperature sensor interface is located at thermostat base, and water pump is taken over the below that interface is located at EGR valve cooling-water temperature sensor interface.Make like this structure of thermostat base compacter and reasonable, the water temperature signal of car load instrument, ECU unit and EGR unit is concentrated on thermostat base and gathers together.Thermostat base carries out " seizing every opportunity " formula design according to the specific spatial structure of diesel engine fully, thus this technological scheme can to remain Diesel Engine Complete Machine boundary dimension substantially constant.
Characteristics of the present utility model and beneficial effect are that thermostat base is simple in structure multiplex, can meet state's III, IV product for the requirement that gathers water temperature signal, and compact structure has well utilized the space of " leaving unused ".This structure setting is development and Design on the basis of state's II product, and all component that are connected with its (state's II diesel engine structure arranges) like this can change, and can save multinomial development and Design cycle and die cost.It is substantially constant that the utility model can be remained Diesel Engine Complete Machine boundary dimension, for installing space has been saved in the assembling of diesel engine car load.

Fig. 3 is the three-dimensional structure diagram of the left apparent direction of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, structure of the present utility model is further described.
Many interfaces thermostat base, its structure is: thermostat base 1 top is connected by flange with thermostat housing 2; With the thermostat base upper flange, be 45 ° and be provided with heater switch device 3; The left side of thermostat base is provided with ECU cooling-water temperature sensor 4; The right side of thermostat base is provided with EGR cooling-water temperature sensor 5; The below of ECU cooling-water temperature sensor is provided with instrument cooling-water temperature sensor 6; The EGR(control unit) below of cooling-water temperature sensor is provided with water feeding of water pump and takes over 7; Water inlet is connected to sebific duct 8.In thermostat base, heater switch device interface center line and EGR cooling-water temperature sensor interface center line are 45 ° and cross.
In order to make the parts compact mounting structure of thermostat base for this reason that takes up room be: thermostat base is mounted on engine body by 4 through holes of base, and thermostat housing is connected with 2 M8 bolts hole of thermostat base by 2 through holes on flange.EGR and ECU cooling-water temperature sensor all are fixed on the corresponding interface of thermostat base by the M12 thread section, and instrument cooling-water temperature sensor and heater switch all are installed on the corresponding interface of thermostat base by the NPT3/8 thread section.Water outlet sebific duct one end is fixing with adapter; The other end is arranged on the pump water inlet joint.
This thermostat base is formed by the cast aluminium casting, and ECU cooling-water temperature sensor mounting point and level are at 45 °.Instrument cooling-water temperature sensor and pump water inlet and thermostat base flanged surface distance highly are 55mm, the EGR(control unit) position of cooling-water temperature sensor and thermostat base flanged surface be apart from being highly 26mm, 45 ° of heater switch center line and thermostat base flanged surface angles.
