Description
Technical field
The present invention relates to technical field of automobile engine, in particular to a kind of interior oily bottom with bimetal leaf structure of controlling temperature
Shell.
Background technique
As oil consumption, emission regulation are increasingly stringenter, each Automobile Enterprises are employed new technology on the engine one after another, to meet
Laws and regulations requirement uses EGR technology, Sydney Atkinson-Miller cycle or full MAP control PCJ technology etc. such as in terms of economy.
It is well known that when cold-starting automobile, since the viscosity of machine oil is higher, frictional resistance between engine movements part compared with
Greatly, cause engine economy poor, and run a period of time, after oil temperature is increased to 80 DEG C or so, fuel consumption is
It can improve.
A kind of mount variable oil oil sump, vapour are disclosed in the Chinese invention patent application of Publication No. CN 109139179A
When vehicle is cold-started, the machine oil in interior oil sump is used only in lubricating system substantially, achievees the effect that similar rapid warming-up, when machine oil temperature
When degree is increased to certain value, whole machine oil in inside and outside oil sump participate in greasing cycle again.Interior oil sump bottom in the patent
Portion's side wall is equipped with temperature-conserving valve, and when machine oil reaches set temperature, temperature-conserving valve is opened, and machine oil flows into outer oil sump.But existing section
Warm valve is opened using paraffin volume expansion, and it is easy to damage to have the disadvantages that structure is complicated, at high cost;Paraffin is mounted in shell
In vivo, machine oil heat is conducted to certain time is needed inside paraffin, causes not prompt enough to oil temperature reacting condition, is opened stagnant
Afterwards.
Bimetal leaf is also referred to as thrermostatic bimetal-plate, since the thermal expansion coefficient of each constituent element layer is different, when the temperature is changed, actively
The deformation of layer is greater than the deformation of passive layer, so that the entirety of bimetal leaf will be then this compound to passive layer curving
The curvature of material changes to generate deformation.Wherein, the coefficient of expansion is higher is known as active layers;The lower title of the coefficient of expansion
For passive layer.Bimetal leaf is widely used in relay, switch, controller etc., but prior art bimetal leaf is only capable of position
In being installed in medium pipeline in valve body, structure is complicated and not can be used directly on the interior oil sump of open type.
Therefore, it is necessary to develop, a kind of structure is simple, the willing interior oil sump with bimetal leaf structure of controlling temperature.
Summary of the invention
The purpose of the present invention is to solve the deficiency of the above background technology, and it is simple, willing to provide a kind of structure
Interior oil sump with bimetal leaf structure of controlling temperature.
The technical solution of the present invention is as follows: a kind of interior oil sump with bimetal leaf structure of controlling temperature, which is characterized in that including
Shell and bimetal leaf component,
Oil leak hole is opened up on the shell, by Curved when draining bore closure and heat under the bimetal leaf component room temperature
Oil leak hole is opened in change.
Preferably, the bimetal leaf component includes that claw and heat bend the bimetallic of deformation along its length
Bimetal leaf is fixed on shell by piece, the claw.
Further, the shell is equipped with the mounting groove of indent, and oil leak hole is opened on mounting groove slot bottom, the installation
Clamping structure cooperation claw is equipped in slot to fix bimetal leaf head end.
Further, the clamping structure is the Y type bracket uniformly extended along bimetal leaf width direction, the Y type
Bracket includes that mounting groove slot bottom extends to form substrate and substrate at the fork plate for closing on the setting of shell side, the fork plate both ends
It is connect equipped with connection sheet with shell.
Further, claw includes corpus unguis and the card that is bent to form in corpus unguis one end corresponding with bimetal leaf head end
Hook, the corpus unguis extend towards bimetal leaf tail end and are gradually distance from oil leak hole, and the grab end is equipped with first latching tooth.
Further, bimetal leaf head end is bent to is bonded with substrate end-face, and the grab compresses the head of bimetal leaf
End and first latching tooth and fork plate close on the clamping of shell side, and the grab two sides and connection sheet cooperation limit.
Further, the cell wall of the mounting groove forms installation groove with respect to evagination, and it is recessed that the corpus unguis is installed on installation
In slot and bottom and installation groove are clamped.
Further, leak holes corresponding with oil leak hole are offered on the corpus unguis, the corpus unguis is wide along bimetal leaf
The two sides for spending direction are equipped with the first flange and the side wall of installation groove cooperates.
Further, the corpus unguis bottom is equipped with the second flange, is equipped with gag lever post in the installation groove, and described second
Flange is equipped with the second latch and gag lever post cooperation is clamped.
Further, the oil leak hole be towards the curved curved hole of enclosure interior, the bimetal leaf be under room temperature with
The arc-like sheet of oil leak hole fitting, tail end is towards claw Bending Deformation to being bonded with claw when the bimetal leaf heat.
Preferably, the thermal expansion coefficient that draining mesoporous metal member layer is closed in the bimetal leaf is greater than far from draining mesoporous metal
The thermal expansion coefficient of first layer.
Bimetal leaf head end, tail end refer to the both ends of length direction in above scheme, and any end is head end, and the other end is
Tail end.
The invention has the benefit that
1. bimetal leaf is directly contacted with machine oil, draining bore closure is bonded under room temperature, when machine oil is warming up to preset temperature
The rapid temperature-sensitive of bimetal leaf energy, itself Bending Deformation open oil leak hole in time.
2. only installing bimetal leaf by mounting groove on shell and claw, other installing components are not necessarily to, claw is not only
Bimetal leaf head end is connected and fixed, and extends outwardly away from oil leak hole towards tail end, is formed between mounting groove for bimetal leaf tail end
The space of flexion, and bimetal leaf bending deformation state is limited.
3. component is few, installation is quickly, at low cost, and when oil temperature is increased to preset temperature, bimetal leaf is by oil leak hole
It opens, inside and outside oil sump machine oil intercommunication, whole machine oil participate in circulation, guarantee the normally travel of engine, prevent too fast machine oil from splitting
Change.
