Abstract
The invention discloses a special-shaped oil pan applied to a single-cylinder engine of an energy saving vehicle. At present, a traditional oil pan technology has such defects as oil leakage and insufficiency of lubrication. The special-shaped oil pan has the characteristics of capability of storing enough lubricant, excellent lubrication effect, light weight, no oil leakage and obvious vibration resisting effect. The special-shaped oil pan is realized through the technical scheme: the special-shaped oil pan is assembled by three parts of a contact flat plate, a main oil storage chamber and an auxiliary oil storage chamber; the main oil storage chamber and the auxiliary oil storage chamber are connected with the contact flat plate as a whole; the contact flat plate realizes the fastening bolt connection with the lower end of a crankcase through four bolt holes in the contact flat plate; the positions of the four bolt holes are determined according to fixed points of an engine body; and a layer of sealing ring for assisting the sealing is cushioned between the contact flat plate and the lower end of the crankcase.
Description
Technical field
The present invention is a kind of oil sump storing lubricant oil about energy saving vehicle single-cylinder engine.
Background technique
The energy-conservation sports contest of Honda China is initiated by Honda founder Mr. Soichiro Honda, establishes, have every year and take part in game more than 500 fleets in 1981 in Japan.From Honda China in 2007, China was come in energy-conservation sports contest, had successfully held 6 up to now.Unified 125cc low oil consumption 4 two-stroke engine provided of Honda is carried in match, and vehicle frame and vehicle body etc. then independently have been created by each fleet, finally how much plays off for the victory with the consumption of fuel oil.Omnidistance 5.277 kilometers of match, each racing car completes match at 26 points in 12 seconds, measures the oil consumption of 5.277 kilometers, amounts to into the mileage that often liter of oil can travel.The energy-conservation sports contest of honda in 2012, Ken Saiche team of Jilin University has won the champion of university's group, and achievement is 1042.3.3km/L, and the contest of energy-conservation sports Japan creates the record of 3435 kilometers/liter especially in calendar year 2001.
The key of match is the low oil consumption single cylinder engine for motorcycle of a 125cc, because enforcement 5.77 kilometers is only required in match, to the durability of motor and stability requirement not high, therefore motor is all carried out loss of weight transformation by all teams participating in the contest substantially.Excise unnecessary parts, as gearbox, radiating fin etc.Only remain primary transmission or two-stage drive part.Such machine rebuilding will certainly cause the lubrication system of motor to be seriously damaged, and thoroughly exposes at the bottom of crankcase.In order to ensure the normal lubrication of engine movements part, the mode that most of team participating in the contest all employ the bonding motor lower end of massive plate realizes storing machine oil, so not only insufficient strength, and lubrication effect is very poor, and especially easily leakage of oil, and quality is also larger.The present invention, according to the shape facility of improved engine crankshaft lower end, have devised a kind of special-shaped oil sump.Through calculating, this oil sump intensity is qualified, can not only store enough machine oil, and can ensure that sealing is intact, and unlikely leakage of oil, quality only has 1kg.
Summary of the invention
Seal that the lubrication effect occurred is poor to overcome the bonding oil storage of existing metal plate, leakage of oil and the large shortcoming of quality, the invention provides a kind of scheme of special-shaped oil sump.
The technical solution adopted in the present invention is integral type abnormity oil sump, for protruding two little cuboid grooves in the middle of cuboid plate, mainly can be divided into three parts: contact is dull and stereotyped, main apotheca, additional storage room.In order to ensure leakage of oil not to occur between apotheca and contact flat board, namely the present invention, by apotheca and contact the integral formula of slab design, does not have bonding yet and welds.Contact is dull and stereotyped and bent axle lower end is with bolts, and centre is added with one deck seal ring.In order to overcome the shortcoming that existing oil sump oil storage deficiency causes lubrication effect undesirable, the present invention is well-designed two accumulators, main accumulator can store the lubrication of movement parts in enough lubricant oil supply connecting rods and valve cage, the lubricant oil of auxiliary oil reservoir chamber can the external gear of sufficient lubrication, and, the profile design of auxiliary oil reservoir chamber becomes can tackle the lubricant oil that gear sputters, and overcomes " getting rid of machine oil " shortcoming of prior art.
Relative to existing metal plate Binding scheme, the present invention has following advantage:
1. intensity is high, and anti-shake performance is good.Adopt integral type to be connected with bolt, rigidity is comparatively large, produces huge vibrations when can resist engine operation.
2. good airproof performance.Do not have gap between apotheca and flat board, dull and stereotyped and bent axle lower end adopts seal ring sealing, and under the pretightening force effect that bolt is larger, flat board, seal ring, bent axle lower end three firmly combine, unlikely leakage of oil.
3. quality is light.Adopt full aluminum to do, by calculating, oil sump only has 1kg heavy, has very large contribution to motor loss of weight.
4. lubricity is good.Can store enough machine oil, and heat diffusion area is large, lubrication effect significantly improves.

Embodiment
The present invention is a kind ofly applicable to the oil-storing lubricating device of energy-conservation sports contest single-cylinder engine, can realize after engine mechanical transformation, seal its crankcase, store machine oil and leakage of oil does not occur, meet the requirement of structural strength.
For the implementation methods of the present invention of understanding clearly and application, below in conjunction with accompanying drawing, the invention will be further elaborated.
Fig. 1 is the distribution situation of all parts in the present invention.Wherein 1 is contact flat board, and 2 is main apotheca, and 3 is fixed bolt holes, and 4 is auxiliary oil reservoir chamber.Contact section that is dull and stereotyped and crankcase lower end is fitted, and because the crankcase lower end shape matching of machine rebuilding rear engine is special, therefore will measure it and draw.The shape of abnormity oil sump is also design according to the shape of crankcase lower end.The machine oil that main accumulator stores mainly supplies the lubrication of movement parts in connecting rod and valve cage, and the machine oil in auxiliary oil reservoir chamber is used for the lubrication of external driving gear.Four bolts hole on base plate are used to be connected use with engine body, are also overall engine and vehicle frame tie point simultaneously.In order to reach the object of loss of weight, by oil sump contact plate longitudinally two tip cut-offs two-part, can material be saved and loss of weight, can ensure that again bulk strength is enough.Redundance between two apothecas also does corresponding excision.
