Description
Technical field
The utility model relates to motor, specifically, relates to a kind of engine cylinder-body stiffening plate.
Background technique
Diesel engine generally adopts oil sump welding baffle plate or baffle plate is installed on cast aluminum sump at present, reduce in vehicle movement machine oil with this rocks and causes machine oil to mix with air in oil sump, make large quantity of air enter machine oil, can also avoid motor climb and fall oil pump cannot be drawn onto machine oil and be drawn onto air.But the restriction that installed by link motion track and punching press baffle plate, baffle plate cannot cut off contacting of machine oil pasta and the interior air of engine cavity, must cause large quantity of air to enter into the machine oil of oil sump.Mainly there is following problem in current existing structure:
1. oil delivery is arrived bent axle, camshaft place by oil pump, lubricated bent axle, camshaft guarantee its normal operation, but the oil bubbles that contains gas is broken in extrusion process, the bubble impact bearing shell breaking causes bearing shell cavitation pitting, thereby causes the faults such as motor damage;
2. oil sump simplicity of design and can not strengthen engine cylinder-body rigidity, causes engine luggine, defect that noise is large on the contrary;
3. because the movement parts such as engine crankshaft, camshaft adopts oil lubricating, movement parts runs up and is with engine oil to splash, make the closed chamber inner engine oil of motor fully mix and swim in air with air, gas in cylinder block enters into pressurized machine and firing chamber through forced ventilation structure, enters into firing chamber burning in a large number cause motor discharge to exceed standard also may to damage motor simultaneously containing the air of organic oil.
In sum, there are some defects in existing design proposal, is therefore necessary to research and develop the stiffening plate that a kind of new engine cylinder-body is used, to address the above problem.
At present, we retrieve the open source literature of some engine cylinder-body stiffening plates, for example:
1. Chinese Patent Application No. 200820034672.4, in open day on January 28th, 2009, this application case discloses a kind of reinforcing plate of diesel engine crankshaft case, and it relates to the reinforcing plate of diesel engine crankshaft case supporting with diesel engine body.Reinforcing plate of diesel engine crankshaft case is the recessed rectangular plate-like in middle part, and its length direction dual-side is respectively equipped with 6-10 mounting hole, is provided with one or more stiffening rib in the middle part of its width direction, stiffening rib both sides uniform more than one spill port.Stiffening plate material is steel plate, and thickness range is 4-8 millimeter.Its deficiency is: the machine oil of falling drops in the machine oil of oil sump from spill port can bring air into, therefore poor effect.
2. Chinese Patent Application No. 201220022654.0, open day on November 14th, 2012, this application case discloses a kind of cylinder body stiffening plate, engine cylinder-body is strengthened structure, motor and automobile, it comprises cylinder body stiffening plate, the size of this cylinder body stiffening plate (2) is configured as at this cylinder body stiffening plate (2) and is installed under the state of described engine cylinder-body (1) bottom, and this cylinder body stiffening plate (2) is corresponding to the partial cylinders at least two cylinders in described engine cylinder-body (1).Its deficiency is: 1. the machine oil falling after rise drops in the machine oil of oil sump from spill port can bring air into, therefore poor effect; 2. integral rigidity is poor.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide that a kind of machine oil entrained air amount is few, oil consumption is little, effectively strengthens the motor cylinder body stiffening plate of engine cylinder-body skirt section intensity.
For achieving the above object, the utility model is realized by following scheme:
A kind of engine cylinder-body stiffening plate, described engine cylinder-body stiffening plate comprises flange joint and connected framework, described framework is hollow rectangle, and inside is provided with arc T-shaped type muscle and vertical stiffening rib, and described arc T-shaped type muscle and vertically stiffening rib are being divided into several separate spaces in framework.
Described arc T-shaped type muscle head and the tail are not connected mutually, and height staggers.
Described framework comprises cylinder body attachment face, and described cylinder body attachment face is provided with machine oil return flow line.
Described flange joint is connected with framework by stiffening rib.
Working principle of the present utility model: adopt arc T-shaped type muscle and vertical rib that in-engine machine oil is divided into fritter in stiffening plate framework, reduce vehicle machine oil slosh in operation process, because having reduced oil gas contact, the existence of rib amasss, thereby reducing machine oil in body stiffening plate mixes with air and causes air to be dissolved in machine oil, arc T-shaped type muscle is conducive to collect and in motor cavity, splashes in airborne machine oil, machine oil is assembled on arc T-shaped type muscle, reduce airborne machine oil oil content in motor cavity, in air, machine oil content has lacked, can reduce forced ventilation motor like this and enter the oil level of pressurized machine or engine air in-cylinder combustion, not only guarantee engine reliable work but also reduced engine motor oil consumption, integral rigidity can increase well body skirt section intensity simultaneously, be conducive to reduce motor machine vibration and noise.
Compared with prior art, the utlity model has following beneficial effect:
1. machine oil entrained air amount is few.The utility model does not want that by head and the tail the arc T-shaped type muscle connecting becomes one by one separate space independently with vertical stiffening rib stiffening plate internal insulation, effectively stop machine oil rocking in vehicle movement, height and amplitude that machine oil splashes are weakened, machine oil and air mixing phenomena are reduced, effectively reduce the mixed volume of air in machine oil, compare traditional design, larger prolongation the time of engine bearing generation cavitation pitting, ensure motor long-time steady operation.
2. oil consumption is little.Thereby structure of the present utility model has stoped rocking of machine oil to reduce machine oil content in the interior gas of motor cavity, thereby the oil level that enters combustion chambers burn is reduced, reduce engine motor oil consumption, reduce motor discharge, ash content, the pollution of carbon distribution to oil sump machine oil of avoiding too much machine oil burning to produce, and stop up oil sprayer spray orifice and cause engine performance to worsen, the sulphate of simultaneously having avoided machine oil burning to produce makes reprocessing poison deactivation, has improved the Environmental Protection Level of motor.
3. effectively strengthen engine cylinder-body skirt section intensity.With respect to traditional scheme of installing or welding baffle plate on oil sump, the utility model adopts die casting aluminium one-body molded, and inside is provided with many stiffening ribs, and integral rigidity is better, increase the intensity in engine cylinder-body skirt section, can reduce the noise of motor because of generation of vibration.
