Abstract
The utility model relates to a left cover air cooling structure of a motorcycle horizontal engine, which comprises a driving wheel chamber and a driven wheel chamber. The driving wheel chamber is separated from the driven wheel chamber through a separator. An air inlet is arranged at the side wall windward side of the driving wheel chamber of a left cover and an air outlet is arranged at the side wall of the driven wheel chamber of the left cover. A sealing board is added to the driving wheel chamber of the left cover. The sealing board is provided with a driving wheel installation through hole corresponding to the installation position of a driving wheel of the driving wheel chamber. The sealing board is provided with heat radiation ribs. In this way, when the motorcycle engine starts, natural air enters the driving wheel chamber from the air inlet which is arranged at the side wall of the driving wheel chamber of the left cover and then enters a left cover space at the upper part of the sealing board through the driving wheel installation through hole on the sealing board. Driven by the high speed running of the driving wheel, a belt and a driven wheel, the natural air fills the whole space, absorbs a great amount of heat and then is discharged out of the air outlet which is arranged at the side wall of the driven wheel chamber of the left cover. Consequently, parts which run at a high temperature in the engine are cooled effectively and the thermal load coefficient of the parts is greatly reduced.
Description
Technical field
The utility model relates to a kind of left side lid structure of motorcycle engine, relates in particular to a kind of left side lid air-cooled structure of motorcycle horizontal engine.
Background technique
Existing motorcycle horizontal engine left side lid is assemblied in the left box body side of motor, the belt that is equipped with driving wheel, follower in the left box body and connects driving wheel and follower, pin starting mechanism etc.During engine operation, the temperature conduction of piston, cylinder, cylinder head is to left box body and Zuo Gai; Simultaneously, fricative temperature also accumulates in a left side lid when driving wheel, follower, belt work, and the temperature at lid middle part, a left side has been greater than or equal to the operating temperature of motor.The high temperature that motor zero, parts running produce by lubricated cooling machine oil by the oil pump pump behind cylinder head, cylinder head cover, finally can gather the oil sump direction that flow to crankcase from the following spill port of chain chamber.The flushing of a large amount of machine oil no doubt can provide the good lubricating effect of piston, cylinder and cylinder head, take away the high heat temperature of its absorption, make parts in normal temperature work, but lubricating oil path does not communicate with left side lid, the heat that the parts of running produce between left box body and the left side lid can not dissipate timely, can not ensure the normal working temperature of the parts that respectively turn round.Main, follower, the high temperature of belt and each parts can make the useful horsepower of motor reduce, transmission efficiency reduces, the surface of contact of inorganic oil in addition, the working environment at left box body and left lid place is very abominable, the temperature that a left side covers is along with the operating time of motor is long more and high more, the component of high temperature can not get the cooling of lowering the temperature timely, like this, engine load is big, the road conditions complexity, long-time running makes engine power performance power (transmission efficiency) descend, quicken unable, oil consumption increases, deterioration of lubricant etc., cooling effect to the relevant running component of motor weakens gradually, quicken the wearing and tearing of component, even cause the damage of engine interior component or scrap, significantly reduce the working life of motor.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of left side lid air-cooled structure of the motorcycle horizontal engine that can dispel the heat.
Technological scheme
The purpose of this utility model is achieved in that a kind of motorcycle horizontal engine left side lid air-cooled structure, comprises driving wheel chamber, follower chamber, and driving wheel chamber and follower chamber are separated by dividing plate.On the sidewall windward side, driving wheel chamber of left side lid, establish an intake grill, on the follower chamber sidewall of left side lid, establish an exhaust outlet.Add a sealing plate on the driving wheel chamber of left side lid, the driving wheel mounting point of the corresponding driving wheel of sealing plate chamber is provided with is convenient to driving wheel installation via hole, is provided with the heat radiation rib on the sealing plate.
Beneficial effect:
Owing to adopted technological scheme described in the utility model: during motorcycle engine work, it is indoor that the intake grill of the driving wheel chamber sidewall that natural air covers from a left side enters driving wheel, by sealing plate the installation via hole of driving wheel enter the Zuo Gai space on sealing plate top, under the drive that runs up of driving wheel, belt, follower, after making natural air be full of whole space and absorbing a large amount of heats, discharge from the exhaust outlet of the follower chamber sidewall of left side lid again.Like this, the running gear of high temperature has obtained effective cooling in the motor, and part heat load coefficient reduces greatly.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the plan view of the utility model embodiment one described motorcycle horizontal engine left side lid air-cooled structure.
Fig. 2 is the left side lid plan view of the utility model embodiment one described motorcycle horizontal engine left side lid air-cooled structure.
Embodiment:
Be further described below in conjunction with the concrete structure of accompanying drawing the utility model embodiment.
With reference to Fig. 1, Fig. 2, be described motorcycle horizontal engine left side lid air-cooled structure, comprise driving wheel chamber 1, follower chamber 2, driving wheel chamber 1 and follower chamber 2 are separated by dividing plate 3.Establish an intake grill 11 on the sidewall of the driving wheel chamber 1 of left side lid, establish an exhaust outlet 21 on the sidewall of the follower chamber 2 of left side lid.Add a sealing plate 4 on the driving wheel chamber 1, sealing plate 4 is provided with the rib 41 that increases heat diffusion area, and the driving wheel mounting hole 12 of sealing plate corresponding driving wheel chambers 4 is provided with a driving wheel via hole 42 is installed.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.All foundations technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. air-cooled structure is covered on a motorcycle horizontal engine left side, comprise driving wheel chamber, follower chamber, driving wheel chamber and follower chamber are separated by dividing plate, its special way is: establish an intake grill on the sidewall windward side, driving wheel chamber of left side lid, on the follower chamber sidewall of left side lid, establish an exhaust outlet, add a sealing plate on the driving wheel chamber of left side lid, the driving wheel mounting point of the corresponding driving wheel of sealing plate chamber is provided with is convenient to driving wheel installation via hole.
