Abstract
The utility model relates to a front-driving electric-spraying gasoline engine for mini cars. A crankshaft is connected with a piston rod connected with a piston, the outer shaft end of the crankshaft is fixed with a pulley, and the inner side of the crankshaft is fixed with a driving synchronizing chain wheel. A chain is arranged on the driving synchronizing chain wheel, and the outer side of the crankshaft is provided with an outer cover and a motor-oil pump shell. Through improving the structure of the original engine, the utility model redesigns a front-driving electric-spraying gasoline engine suitable for the mini cars. The utility model redesigns the gasoline engine, the engine can be arranged conveniently on the front-driving mini cars of which the front wheel track is 1200MM, and the driving performance and the comfortable property of the front-driving mini cars with small wheel track are satisfied.
Description
The utility model relates to a kind of petrol engine, particularly a kind of minicar forerunner electronic injection gasoline engine.
As shown in Figure 1, existing minicar engine belongs to mid-, rear-guard dynamic formula motor.Its structure has following characteristics: 1, the enclosing cover of timing mechanism and oil pump enclosing cover are two independently parts; 2, the toothed belt transmission is adopted in the transmission of timing mechanism; 3, the water pump of water inlet system is arranged in the front end of motor.Existing minicar 4 Cylinder engines all are the rear driving motors, and except the speed changer of the body of its motor, other length is all very long, and can not satisfy front tread is the front wheel driving minicar of 1200mm.
The purpose of this utility model provides a kind of compact structure, and function admirable can be crossed and satisfy the minicar forerunner electronic injection gasoline engine that forerunner's minicar is used.
The purpose of this utility model realizes by following structure: a kind of minicar forerunner electronic injection gasoline engine, bent axle is connected with piston rod, piston rod connects piston, bent axle outside axle head is installing and fixing belt pulley, the active synchronization sprocket wheel is being fixed in the bent axle inboard, be equipped with chain on it, the bent axle outside is installed with enclosing cover and oil pump housing assembly, and sprocket wheel fixing on the water pump main shaft is connected with chain with the inboard active synchronization sprocket wheel of bent axle.
The utility model redesigns out the electronic injection gasoline engine that is fit to the minicar front wheel driving by the architecture advances to prototype: DA462-1A.The utility model has redesigned petrol engine, and motor can be installed on the front wheel driving minicar that front tread is 1200mm smoothly, has fully satisfied the minicar cornering ability and the ride comfort performance of front wheel driving steamboat distance.The utility model has reached following technique effect: 1, cancelled cap assembly in oil pump pad and the synchronous cog belt, engine oil pump assembly moved outward to make the outer cap assembly and two of oil pump enclosing cover and toothed belt be one, simultaneously the convex portion of oil pump is embedded in the crank pulley (having the air-conditioning belt pulley) of redesign 2, the transmission of timing mechanism adopts chain transmission; Chain is the short pitch precision roller chain; 3, the water pump that will directly influence engine body length rearranges air inlet side at motor by original motor head, simultaneously in order also to have set up the water inlet adapter with being connected of cylinder block.4, in order to increase the heat load ability of piston, change the original drain pan of piston into equally distributed draining hole.

Below in conjunction with drawings and Examples the utility model is further described.
Embodiment:
The utility model as described in Figure 2 is that a kind of minicar forerunner electronic injection gasoline engine is a kind of minicar forerunner electronic injection gasoline engine, bent axle 8 is connected with piston rod, piston rod connects piston, bent axle 8 outside axle heads are installing and fixing belt pulley 6, active synchronization sprocket wheel 16 is being fixed in bent axle 8 inboards, be equipped with chain 15 on it, bent axle 8 outsides are installed with enclosing cover and oil pump housing assembly 12, and sprocket wheel fixing on the water pump main shaft 10 is connected with chain 15 with the inboard active synchronization sprocket wheel of bent axle.As shown in Figure 3, water pump main shaft 10 is positioned at the air inlet side of body.
Except the cylinder core distance, the factor that influences engine body length mainly is: for the prototype engine machine have 1., the oil pump pad is the oil resistant asbestos slate; 2., engine oil pump assembly; 3., cap assembly in the synchronous cog belt; 4. active synchronization gear ring washer; 5., active synchronization gear; 6., crank pulley.The utility model motor is then taked: 1, cancelled cap assembly in oil pump pad and the synchronous cog belt, engine oil pump assembly moved outward to make the outer cap assembly and two of oil pump enclosing cover and toothed belt be one, the convex portion with oil pump is embedded in the crank pulley that has the air-conditioning belt pulley of redesign simultaneously.2, chain transmission is adopted in the transmission of timing mechanism; Chain is the short pitch precision roller chain; 3, the water pump that will directly influence engine body length rearranges air inlet side at motor by original motor head, simultaneously in order also to have set up the water inlet adapter with being connected of cylinder block.4, in order to increase the heat load ability of piston, change the original drain pan of piston into equally distributed draining hole.The model utility motor can be installed on the front wheel driving minicar that front tread is 1200mm smoothly, has fully satisfied the minicar cornering ability and the ride comfort performance of front wheel driving steamboat distance.For example: as be loaded on Harbin Aircraft Mfg. Co's hundred sharp cars
The difference of concrete structure of the present utility model and prototype is illustrated by the following drawings: Fig. 1 is the part-structure of prototype: oil pump pad 1; Engine oil pump assembly 2; Cap assembly 3 in the synchronous cog belt; Active synchronization gear ring washer 4; Active synchronization gear 5; Crank pulley 6; Toothed belt enclosing cover 7; Bent axle 8; Toothed belt 9; Water pump main shaft 10.
Fig. 2 is the utility model partial structurtes sectional view bent axle 8; Enclosing cover and oil pump housing assembly 12; Crank pulley 6; Water pump main shaft 10; Chain 15; Active synchronization sprocket wheel 16.
Fig. 3 is the piston portion structure sectional view of motor in the prior art: drain pan 17.
Fig. 4 is the piston portion structure sectional view of the utility model motor: rush down oilhole.
