Abstract

The utility model relates to a starting device for the engine of a motor tricycle. A starting motor is arranged on the box body of an engine crankshaft. The shaft end of the starting motor is provided with a driving gear. Chain gear assembly is fixedly arranged at the end of the engine crankshaft. A starting gear is sheathed on the chain gear assembly. Two intermediate gears are arranged between the starting gear and the driving gear. A chain gear disk is arranged at one end of the chain gear assembly. A cover disk is arranged in an on/off mode at the other end of the chain gear assembly. A notch is arranged on the circumference of the cover disk. A groove is arranged on the gear disk of the starting gear. A centrifugal lock block is arranged in the groove through a pin shaft. If the utility model is arranged on the engine, the engine has the advantages of electric starting and free direction change for traveling.

Description

Starting means of engine for motor tricycle

The utility model relates to a kind of engine for motorcycle starting arrangement.

022 motor of using on the existing 021 type motor tricycle can only be used foot pedal starting, because this engine power is bigger, thereby actuating ratio is required great effort, also can injure starting person's pin if igniting adjustment on opportunity is inaccurate, though can solve starting problem if load onto common electric starter, but run into the tricycle astern condition, starter motor will damage because of hypervelocity.

The purpose of this utility model is to provide a kind of engine for motorcycle starting arrangement, and this device can not only solve the electric starting problem, and allows engine inversion, and motor tricycle can move forward and backward easily.

The purpose of this utility model is achieved in that a kind of engine for motorcycle starting arrangement, actuating motor is arranged, driving gear, described actuating motor is installed on the described engine crankshaft casing, this actuating motor axle head is equipped with driving gear, engine crankshaft end fixed installation chain wheel assembly, suit starting gear on this chain wheel assembly, two idle wheels are housed between starting gear and the driving gear, chain wheel assembly one end is a clutch cover dish for the chain sprocket the other end, have breach on this cover dish circumference, the wheel disc of starting gear is provided with groove, and centrifugal lock dog is installed in this groove by bearing pin.The utility model is mixed the double platinum firing circuit again, when positive car starting is moving, dragging starting gear by actuating motor counterclockwise rotates, this moment, the head of the centrifugal lock dog in this gear disk groove radially rotated, and the indentation, there that is stuck in centrifugal cover dish drives chain sprocket and rotate together, thereby engine start is got up, actuating motor cuts out thereupon, starting gear stops the rotation, and centrifugal lock dog resets, and starting gear and motor and engine crankshaft break away from drive connection.When need were moveed backward, motor turned clockwise and can realize reverse travel.Realized the engine free commutation.

Therefore, the utility model is installed on the engine for motorcycle, can make motor have electric starting and travel in the advantage that can freely commutate.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1, the utility model drive connection figure.

Fig. 2, Figure 1A-A sectional view

Fig. 3, centrifugal lock dog installation diagram

Fig. 4, the firing circuit schematic diagram

Shown in Figure 1 is a example to 022 engine modification, 022 motor is to aim at the matched two-stroke gasoline engine of motor tricycle, this petrol engine can be equipped with double platinum firing circuit shown in Figure 4, and storage battery 27, spark coil 22, positive and negative car diverter switch 23, spark plug 24, positive car platinum 25 and anti-car platinum 26 are arranged in this firing circuit.The cylinder body 1 of this petrol engine is installed on the crankcase 2, the utility model is installed in the crankcase side, actuating motor 3 is fixed on the crankcase upper right corner, its axle head is driving gear 4 fixedly, engine crankshaft 9 axle heads fixed installation chain wheel assembly 5, one end of (referring to Fig. 2) this chain wheel assembly is that chain sprocket 6 is used for installing drive chain, the other end is a clutch cover dish 7, have a breach 8(on the circumference of this cover dish and see Fig. 3), clutch cover dish and chain sprocket can be whole, also can adopt two other parts to connect firmly into an assembly with pin, this example adopt exactly two in addition part by three pins 13, the chain wheel assembly that connects firmly, suit starting gear 10 on chain wheel assembly, this starting gear can relatively rotate with chain wheel assembly, a round boss is arranged on the starting gear, this boss and clutch cover dish suit, on the round boss of starting gear, offer groove 14, its interior bearing pin 21 fixing centrifugal lock dogs 15 of using of (see figure 3), the stem of this lock dog has V-notch 16, afterbody has two arc notch 17, offer spring groove 18 on the groove right side, spring 19 is housed in it, the decorative pearl on top of an official cap 20 is equipped with on the spring top, this decorative pearl on top of an official cap is against in the arc notch of centrifugal lock dog afterbody, play the role of positioning, make centrifugal lock dog can keep a stable position in the condition that is not subjected to external force, also be provided with two idle wheels 11 between starting sprocket wheel and the driving gear, two axle of carrier pulley 12 all are fixed on the crankcase, cover crankcase cover, the utility model, just can use, though the utility model adopts electric starting, but still keep the mechanism that has ridden, use during in order to the battery power deficiency.
