Abstract
The utility model relates to an engine forced air cooling device, which aims at resolving the problems of engines cooling in a three-wheel motorcycle, a four-wheel beach vehicle and a field vehicle, comprising a forced air cooling device with a fan arranged on an engine frame; the utility model is characterized in that the forced air cooling device is fixed by a plurality of bolts on the dynamic output side of the engine; a main shell is arranged by pins on an engine casing; a gear group for the fan shaft is arranged in a main shell with a bearing; the outer end of the fan shaft is connected to the fan through a flange or a wheel sleeve; the gears of the fan shaft gear group are meshed with the gears on the engine crankshaft; an oil seal is arranged in the connection place of the fan shaft and the main shell. When the engine is started and the crankshaft is rotated; the fan gear shaft assembly is driven into rotating by the gears on the crankshaft, to drive the fan blades into rotating to generate forced wind. The utility model has the advantages of low cost, convenient usage and maintenance, being reliable with long service life, and being suitable for the three-wheel motorcycle, the four-wheel beach vehicle and the field vehicle.
Description
Technical field
The utility model relates to the motor forced air cooling device of using on a kind of motor tricycle, four-wheel beach buggy and the field vehicle.
Background technique
It is poor that the motor with multistage variable block that uses on existing tricycle, four-wheel beach buggy, the field vehicle ventilates owing to the speed of a motor vehicle is low, and ubiquity the problem of cooling difficulty.Be head it off, the car that has uses water cooled engine, but involves great expense, and the heat radiation of water tank need add electric fan, and in addition, outlet pipe can not get cooling, and the hot gas around the motor is difficult for being discharged at the bottom of the car or outside the car; The direct usefulness that has is natural air cooled, and engine cooling is not enough; Also having a kind of is motor band The forced air cooling with the transformation of the way of foot plate bicycle motor, but its blast fan is arranged on the magneto rotor, easily causes the maintenance difficulty and the cost height of the dynamo-electric starting of magnetoelectricity transmission system.
Summary of the invention
The purpose of this utility model be overcome above-mentioned defective and design a kind of cost low, use convenient for installation and maintenance, reliability and durability forced air cooling device.
The technical solution of the utility model is: this motor forced air cooling device, the forced air cooling device that comprises fan is arranged on the engine body, it is characterized in that, described forced air cooling device is arranged on the engine shaft power outlet side by bolt, main casing is with pin and engine housing location, fan shaft gear combination two ends are arranged in the main casing by bearing, the fan shaft outer end is connected with fan by flange or wheel cover, the gear of fan shaft gear combination and the gear engagement on the engine crankshaft are provided with oil sealing at fan shaft and main casing junction.
Work as engine start, during crankshaft rotating, the gear driven fan gear axle combination on the bent axle, fan gear axle combination rotation, the rotation of drive blast fan produces forces wind-force.
Bottom at main casing is provided with two holes corresponding to motor shift axle position place, can be for shift axle, starting shaft are installed.For electricity pilot engine or the user without pin starting or do not need the shift axle is located at the user on motor right side, available stopper is sealed up two holes.
The beneficial effects of the utility model are: 1, open the throttle when car, when the motor heating load increased, wind speed increased, provides the pressure cooling air.2, reliable in structure is durable, and is easy to maintenance.3, cost is low.
Description of drawings
Figure is a main cross-sectional schematic of the present utility model.
Among the figure: 1. main casing, 2. left bearing, 3. fan gear axle combination, 4. right bearing, 5. circlip for hole, 6. oil sealing, 7. flange, 8. fan, the 9. bent wheel of motor.
Embodiment
As shown in the figure.
The forced air cooling device that comprises fan 8 is arranged on the engine body, is arranged on the engine shaft power outlet side by bolt.
The fan gear axle makes up 3 two ends and is installed on the main casing 1 by left bearing 2 and right bearing 4, and circlip for hole 5 is installed on and blocks right bearing 4 in the annular groove.Oil sealing 6 is installed on fan gear axle right-hand member and is used for sealing.Flange 7 or axle sleeve are installed on the fan gear axle, and fan 8 is installed on the flange 7 (or axle sleeve).The gear of fan shaft gear combination and the gear engagement on the engine crankshaft 9.
When engine crankshaft 9 rotations, fan gear axle combination 3 is driven in rotation, and is delivered on the fan 8 by flange 7, and the drives fan wheel rotation produces forces wind-force.
Bottom at main casing is provided with two holes corresponding to motor shift axle position place, can be for shift axle, starting shaft are installed.For electricity pilot engine or the user without pin starting or do not need the shift axle is located at the user on motor right side, available stopper is sealed up two holes.
