Embodiment
Below in conjunction with brief description of the drawings and embodiment, the present invention is described in further detail.
Referring to Fig. 1-Fig. 3, electronics thermoregulator assembly for a kind of heavy duty diesel engine, comprises cover body, joint 5, push rod 6, big spring 7, inductor 8, valve seat 9, valve 10, little spring 11, push-rod lock 12 and support 13; In described inductor 8, be provided with temperature-sensitive cured.Described push rod 6 one end are positioned at inductor 8, and the other end is positioned at outside inductor 8 and is connected with cover body; Push rod 6 inside are provided with heating element, and described heating element is connected with joint 5 by wire, and described joint 5 is positioned on cover body and with automobile ECU and is connected, thereby automobile ECU can be controlled heating element heating.Described valve seat 9 is made up of valve seat base plate 15 and valve seat side plate 16, and described valve seat side plate 16 is cylindrical shell, and valve seat side plate 16 lower ends are connected with valve seat base plate 15 peripheries, and valve seat side plate 16 upper ends are connected with cover body; On described valve seat base plate 15, be provided with supporting rib 17, between described supporting rib 17, form the through hole 19 that supplies water and pass through.Described valve 10 is tubular construction, the upper end of valve 10 is open-mouth end, and it is corresponding with the sealed step in valve seat base plate 15, and the lower end surface of valve 10 is flat mouth structure, the lower end surface of described valve 10 is provided with connecting tendon 18, forms the opening 20 that supplies water and pass through between described connecting tendon 18.Described support 13 upper ends are connected with inductor 8 and are provided with big spring 7 location hooks, described support 13 lower ends are provided with through hole, inductor 8 lower ends are connected with push-rod lock 12 upper ends through the through hole of support 13 lower ends, and described push-rod lock 12 lower ends are connected by the mode of riveted joint with the connecting tendon 18 on valve 10 lower end surfaces.Described big spring 7 is arranged between support 13 upper end location hooks and valve seat base plate 15, and supporting rib 17 on valve seat base plate 15 is used for supporting big spring 7; Described little spring 11 is arranged between the connecting tendon 18 on support 13 lower ends and valve 10 lower end surfaces.
Referring to Fig. 1, preferred, described cover body comprises upper outlet body 1 and lower cover 2, and upper outlet body 1 is connected with motor waterexit end, and lower cover 2 is connected with water feeding of water pump end; Described upper outlet body 1 is connected with lower cover 2, described push rod 6 is connected with lower cover 2, described joint 5 be positioned on lower cover 2 and joint 5 and lower cover 2 by seal ring II 4 or sealant sealing, described valve seat side plate 16 upper ends are connected with lower cover 2.Further, between described upper outlet body 1 and lower cover 2, seal by O RunddichtringO I 3.
Referring to Fig. 4-Fig. 5, preferably, on described lower cover 2, be provided with the stiffening rib 14 of rectangular V-shape; Because lower cover 2 bears valve 10 while the opening counter-force of push rod 6 and the impact force of engine cooling water, therefore the strong muscle 14 of thinner thickness is set at lower cover 2, and the impact force that makes lower cover 2 can bear push rod 6 counter-forces and current can effectively reduce again coolant flow resistance.
Referring to Fig. 1, when work, automobile ECU sends heating or does not heat instruction according to situations such as engine coolant temperature, operating conditions, intake temperature, thereby to the energising of device assembly or the no electric circuit of originally adjusting the temperature electronically.When originally adjusting the temperature electronically after the energising of device assembly, the heating element that is positioned at push rod 6 starts heating, makes the cured thawing of temperature-sensitive in inductor 8, volumetric expansion, and the interior pressure of inductor 8 strengthens; Simultaneously because push rod 6 is fixed on lower cover 2, inductor 8 pressurizeds start to move down, again because inductor 8 is connected with push-rod lock 12 upper ends, push-rod lock 12 lower ends are connected with the connecting tendon 18 on valve 10 lower end surfaces, valve 10 departs from valve seat 9 and also moves downward, valve 10 upper ends are separated with valve seat base plate 15, thereby between valve seat 9 and valve 10, form the circulation passage of hollow, again because valve 10 is tubular construction, so cooling liquid is from 360 ° of evenly outflows of circulation passage of hollow between valve 10 and valve seat 9, therefore, cooling drag is little.Meanwhile, because the lower end surface of valve 10 is flat mouth structure, after valve 10 moves down, will fit with seal face on motor in its lower end surface, thus the circulation passage that throttle down 10 lower end surface upper sheds 20 form; And when now inductor 8 moves downward, belt supporting frame 13 moves together, and in movement process, big spring 7 is compressed.In the time originally adjusting the temperature electronically the power-off of device assembly, heating element stops heating, cured the solidifying of temperature-sensitive in inductor 8, volume-diminished, at pulling force effect lower valve 10, support 13, inductor 8, push-rod lock 12 returns of big spring 7, valve 10 upper ends and valve seat base plate 15 are fitted, and by the through hole 19 on valve seat base plate 15, the opening 20 from valve 10 lower end surfaces flows away cooling water, thereby play the effect of adjusting engine operating temperature, make motor reach best working state.
The device assembly structure that adjusts the temperature electronically of the present invention is simple, and more reliable performance, is active in one's movements, and controls respond wellly, can reduce engine fuel consumption 2%-3%; Reduce CO and HC discharge 5-15%; The discharge of nitrogen oxide is controlled; Reduce soot emissions 20-30%.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, said structure all should be considered as belonging to protection scope of the present invention.
