Abstract

The utility model provides a motorcycle engine comprising a valve train, a crankshaft connecting rod system, a lubrication system, an ignition system and an engine block. A sealed shape cavity is arranged in the oil inlet of an engine oil filtrator inhered in a right crankshaft crankcase cover. A filter is arranged in the shape cavity. The lever section of the right crank which is lengthened extends into the hole of the sealed shape cavity, and sealed by oil seal. The collar extension section of the sealed shape cavity is sealed by a visual cover and a rubber O-shaped ring or an asbestos pad. A piston ring adopts the structure of a plurality of sheet rings; a counter bore which is connected with a starter gear body through rivets and reduces the height of the magneto rotor is arranged at the bottom of the magneto rotor of the ignition system. The utility model can observe, detach, clean the filter at any time, and greatly improves the seal performance at the same time; the motorcycle engine enlarges the space axial direction clearance, and can shorten the redundant height of magnetic cylinder.

Description

A kind of motorcycle engine

Technical field

The utility model relates to the engine modifications technology, specifically motorcycle engine distribution device, crankshaft ﹠ connecting, lubrication system, body, ignition system is carried out improved technology.

Background technique

Mainly there is following defective in the four-stroke vertical engine of prior art:

1, lubrication system mainly is made up of oil pump, oil filter and oil duct etc.Rotary oil filter is made up of oil guide pipe, oil guide pipe spring, oil filter rotor cover, rotor assembly etc. usually, is installed in right crank end, and oil filter is with crankshaft rotating.There are shortcomings such as filtering weak effect, installing/dismounting inconvenience in the oil filter of this structure; Simultaneously, oil filter is difficult to know the self-filtering pollution condition after by housings close.

2, the function of ignition system is that the low tension that generator is exported is become high-tension electricity, on time high-tension electricity is distributed to spark plug by the job order of motor and is produced electrical spark, lights compressed inflammable mixture, makes it the work done of burning.Existing ignition system, it is made up of magnetogenerator ignition, magnetogenerator flywheel, spark coil, high voltage wire and spark plug etc., is fixed with spark coil on the magnetogenerator base plate, and the rotary flyweights that magnet is housed carries out electromagnetic induction and generates electricity.Existing big displacement motorcycle engine magneto rotor is too high, it mainly is motorcycle magneto rotor more than eight grades, because too high some the unnecessary magnetic line of force of magneto rotor fully do not cut, and when engine start, consumed power, wasted fuel oil because of weight is big.

The model utility content

At the prior art above shortcomings, the purpose of this utility model is: at first for overcoming existing filter cleaner filtering weak effect, installing/dismounting inconvenience, being difficult to know inner this shortcoming of oil pollution situation; Secondly, reduce power dissipation, saving fuel oil; Provide a kind of improved motor cycle motor based on this purpose.

The purpose of this utility model is achieved in that a kind of motorcycle engine, comprise distribution device, crankshaft ﹠ connecting, lubrication system, ignition system and body, its improvements are to establish an enclosed shape chamber at the original oil filter oil inlet hole of right crankcase cover place, filtrating equipment is installed in the shape chamber, right toggle-action lever portion lengthening is put in the enclosed shape lumen pore, it is sealed with oil sealing; Add rubber o-ring with visual lid or asbestos packing seals at enclosed shape chamber outer port part.Filtrating equipment can adopt automobile to add filtrating equipments such as rubber or paper filter with steel mesh circular, deltiod.

One to improve part be that the magneto rotor bottom of ignition system is established counterbore and connected the one-way element body by rivet again, or change one-way element into the needle bearing structure and just can cancel connection, and the magneto rotor height is reduced.

Adopt said structure, the utlity model has following advantage:

1, the cyclist can observe engine oil cleaning and filtration situation at any time, in case when seeing that filter is dirty from visual lid, just can easily take visual lid cleaning and filtering apart, has played the effect of clean machine oil greatly.

2, magneto rotor is changed thin, joint bolt is changed into riveted joint, increased space axial clearance, so just unnecessary magnetic cylinder height can be shortened.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is the utility model agent structure schematic representation.

Fig. 2 is the structural representation of the utility model filter cleaner part.

Fig. 3 is the structural representation of the utility model magneto rotor part.

Embodiment

As shown in Figure 1, motorcycle engine comprises distribution device, crankshaft ﹠ connecting, lubrication system, body, ignition system, and the utility model improvements are the oil filtration structure 1 of lubrication system, the piston ring 2 of distribution device and the magneto rotor 3 of ignition system.

As shown in Figure 2, with original oil filter cancellation, at the original oil filter oil inlet hole of right crankcase cover place, if filtrating equipment 5 is installed in an enclosed shape chamber 4 then in the shape chamber, with the former fitting machine oil rectifier bar of right crank 6 portion lengthening, put in the enclosed shape lumen pore, use oil sealing 7 its sealing.In addition, add rubber " O " type circle or asbestos packing at enclosed shape chamber outer port part with visual lid 8 and carry out the oral area sealing.

As shown in Figure 3, change joint bolt 10 into riveted joint after, be about to magneto rotor 9 and change thinly, increase space axial clearance, so just unnecessary magnetic cylinder height can be shortened, thereby alleviate the weight of magneto rotor, save power and fuel oil greatly.

The utility model is not limited to the structural type of above-mentioned embodiment, the conversion that it will be apparent to those skilled in the art that or substitute and remodeling all falls among the protection domain of the present utility model.

Claims

1, a kind of motorcycle engine, comprise distribution device, crankshaft ﹠ connecting, lubrication system, ignition system and body, it is characterized in that covering original oil filter oil inlet hole place at right crankcase, an if enclosed shape chamber (4), establish filtrating equipment (5) in the shape chamber, right crank (6) bar portion lengthening is put in the enclosed shape lumen pore, use oil sealing (7) its sealing; Establish at enclosed shape chamber (4) outer port part that visual lid (8) adds rubber o-ring or asbestos packing seals.

2, motor according to claim 1 is characterized in that counterbore is established by rivet (10) connection one-way element body in magneto rotor (3) bottom of ignition system, and magneto rotor (9) is highly reduced.
