Abstract
The utility model discloses a simple water cooling cylinder body of a motorcycle engine, which comprises a main body of the cylinder body. The utility model has the improvement that a casing layer is arranged on the outer surface of the main body of the cylinder body, a cooling water passage is arranged between the casing layer and the wall of a cylinder barrel, and a water inlet hole and a water outlet hole are arranged on the casing layer. The simple water cooling cylinder body has the advantages of simple structure, high durability and good cooling effect. After the device is adopted, the average temperature of lubricating oil is 15 to 20 DEG lower than the temperature of the lubricating oil which adopts natural wind cooling through tests. Matching and installing dimensions and the precision of the cylinder body are not changed, connecting and matching relation of the cylinder body and other components is not changed, and the utility model has high universality. Cooling water is naturally circulated, and the output power of the engine is not consumed. Costs are not increased basically, and the utility model can accommodate the need of markets.
Description
Technical field
The utility model relates to a kind of motorcycle engine cylinder body, especially motorcycle engine plain type water-cooled cylinder body.
Background technique
At present, the motor of float amount motorcycle comprises and the motor of two-wheeled and motor tricycle mostly adopts nature air swept type, relies on air flows to dispel the heat; In order to improve cooling effect, just must increase heat diffusion area, all be cast with radiating fin in the periphery of cylinder block.Adopt the motorcycle of nature air swept type structure, its deficiency mainly is that cooling effect is undesirable, especially in the summer of weather sweltering heat, has influenced the proper functioning of motor to a certain extent, reduces its output power.Particularly for motor tricycle, because the overcover of its front is more, air flows itself is just not really smooth and easy, be in maximum or very big output torque, and be that uphill way or load-carrying are bigger again, during slow situation of travelling speed, its air cooling effect is poorer, and the motor of this moment is owing to be in maximum or very big output torque state, be to need most when in time being cooled, but because its travelling speed is relatively slow, can not rely on flowing fast of air in time to obtain the good effect that cools, cause engine overheat, and then reduce its output power, shorten its operating life etc.
In the prior art, the water-cooled motorcycle engine of employing is also arranged, name as the application of Lifan, Chongqing company is called " water-cooled engine ", the patent No. is the utility model patent of ZL01214087.2, it adopts parts such as water pump body (comprising water pump gear, axle, impeller etc.), cooler, bearing, spring, can reach that rate of cooling is fast, the effect of good cooling results.But its deficiency is a complex structure, and component are more, need do corresponding change to housing structure, and wants the part output power of consumption of engine to drive the water pump gear rotation.
Summary of the invention
The utility model adopts natural air cooled deficiency at motor tricycle of the prior art, provide a kind of simple in structure, durable in use, do not increase the motorcycle engine plain type water-cooled cylinder body of cost substantially.
The technical solution of the utility model: motorcycle engine plain type water-cooled cylinder body, comprise the cylinder body body, its improvements are: be provided with outer shell layer on described this external surface of cylinder body, between outer shell layer and cylinder barrel wall, be provided with cooling water channel; On outer shell layer, be provided with water inlet and osculum;
Described cooling water channel is a sealed cavity, is arranged in the space range of peripheral about 270 degree of cylinder barrel wall.
Motorcycle engine plain type water-cooled cylinder body of the present utility model, simple in structure, durable in use; Good cooling results, adopt this device after, the temperature of lubricant oil is than adopting natural air cooled average low 15-20 degree after tested; Do not change cooperation, installation dimension and the precision of cylinder body, constant with being connected of other parts, matching relationship, highly versatile; Cooling water is by natural circulation, the not output power of consumption of engine; Substantially do not increase cost, can adapt to the needs in market.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the natural air cooled engine cylinder-body structural drawing of available technology adopting.
Fig. 2 is the utility model housing structure plan view.
Fig. 3 be Fig. 2 along A-A to sectional view.
Fig. 4 be Fig. 2 along B-B to sectional view.
Embodiment
In Fig. 1,1-cylinder body body, 2-radiating fin.Figure 1 shows that blower cooled engine cylinder body of the prior art, especially for the engine cylinder-body of 110,150 type motor tricycles.Being provided with cylinder barrel, chain chamber (push rod chamber), location and installation hole etc. in the cylinder body body 1, all being provided with radiating fin 2 in its side, generally is on its 3 sides radiating fin 2 to be set.Cylinder body body 1 through the location and installation hole etc. with other assembly of motor, link together as cylinder head cover, crankcase etc.As prior art, be not described further at this.
In Fig. 2,3,4,1-cylinder body body, 3-outer shell layer, 4-water inlet, 5-osculum, 6-cylinder barrel wall, 7-cooling water channel.
Simple and easy water-cooled housing of the present utility model, comprise cylinder body body 1, cylinder body body 1 is provided with the cylinder barrel identical with air-cooled cylinder body of the prior art, chain chamber (push rod chamber) and location and installation hole etc., be that cylinder barrel of the present utility model, chain chamber (push rod chamber) and location and installation hole, installation precision etc. do not change substantially, it remains unchanged substantially with being connected of other assembly of motor, positioning relation.
Improvement of the present utility model is as follows: the radiating fin on the cancellation cylinder body body 1, on cylinder body body 1 outer surface, set up outer shell layer 3, and outer shell layer 3 is provided with water inlet 4 and osculum 5, and water inlet 4 links to each other with water tank respectively with osculum 5 again.Between outer shell layer 3 and the cylinder barrel wall 6, cooling water channel 7 is set,, plays the effect of heat exchange between cooling water and the cylinder barrel wall 6 as the flow of cooling water passage.Outer shell layer 3 of the present utility model is identical with the material of cylinder body body 1, the cast iron that is commonly used, and shell 3 and the 1 one-step casting moulding of cylinder body body become an overall structure; During casting, between shell 3 and cylinder barrel wall 6, core is set, just obtains cooling water channel 7 at last.Cooling water channel 7 is arranged in the space range of cylinder barrel wall 6 peripheral about 270 degree as the cavity of relative closure, and promptly (push rod chamber) side is not provided with this cooling water channel 7 in the chain chamber.
When actual fabrication, the thickness of outer shell layer 3 and cylinder barrel wall 6 should be decided by process parameter; Simultaneously, outer shell layer 3 also can be inequality with the material of cylinder body body 1, and material will not increase manufacturing process simultaneously, correspondingly will increase cost.
Working procedure of the present utility model: with cylinder body of the present utility model with after other assembly of motor is connected, installs, water inlet 4 and osculum 5 are connected with external cooling water tank, cooling water enters cooling water channel 7 from the water inlet 4 that is arranged in relatively low position, plays the effect of water-cooled; According to thermal convection principle, hot water flows back to cooling water tank from the osculum 5 that is arranged in relative higher position, plays hydronic effect then.
