Description
Technical field
The present invention relates to and matching used starter of explosive motor and generator, particularly the engine electromechanical assembly of collection starter and generator one.
Background technology
Existing compact internal combustion engine is when starting, and all outside starting of employing or two cover independent agencies start and power.One cover is starter (mainly by direct current series motor, transmission mechanism and control device, its function is the circuit that switches on or off between motor and storage battery, makes driven wheel and the flywheel ring gear engagement or the disengaging of starter), and another set of is generator.The general volume of the employed equipment of this mode is big, complex structure, toggle speed is slow, security performance is relatively poor.
Summary of the invention
The purpose of this invention is to provide a kind of starting-generating integration structure that is used for compact internal combustion engine that a kind of volume is little, in light weight, simple in structure, integrate starting and generate electricity.
The object of the present invention is achieved like this: a kind of starting-generating integration structure that is used for compact internal combustion engine, comprise the starter toothed wheel that is installed on the engine shaft, starter toothed wheel is installed on the engine shaft through first unilateral bearing, the gear that initiatively generates electricity is installed on the engine shaft through second unilateral bearing, and first unilateral bearing is opposite with the installation direction of second unilateral bearing; Also has brushless electric machine, initiatively starter toothed wheel and generating gear are installed on the brushless electric machine axle, active starter toothed wheel and starter toothed wheel engaged transmission, initiatively the number of teeth of starter toothed wheel is greater than the number of teeth of starter toothed wheel, initiatively generate electricity gear and generating meshed transmission gear, the number of teeth of the gear that initiatively generates electricity is less than the number of teeth of the gear that generates electricity.
Above-mentioned brushless electric machine is three-phase brushless magneto or direct current permanent magnet motor.
In the technical program, adopt three-phase brushless permanent magnet motor or dc permanent magnet motor; Engine initiatively is provided with two unilateral bearings that installation direction is opposite, structure is identical on the output shaft, takes not have the gap mode switch; When motor is initiatively worked, the unidirectional mechanism of the starter toothed wheel that speed reducing ratio is bigger locking, and therefore the unidirectional unlatching of generating gear can pilot engine; When engine is initiatively worked and output speed during greater than motor, or motor is when initiatively quitting work, owing to be subjected to the variation of force direction to cause the unidirectional mechanism of starter toothed wheel to be opened, the unidirectional mechanism of generating gear opens, generating gear unidirectional locking realizes that machinery does not have the conversion of intermittently starting, generating direction.
Motor turns clockwise when initiatively powering, and pilots engine to begin to rotate; When the engine start rotating speed surpassed minimum normal running speed, no longer initiatively motor was given in power supply, and motor this moment active rotation no longer drives the power transmission shaft rotation by engine, and motor is converted to generator.
The invention has the beneficial effects as follows: have advantages such as volume is little, in light weight, simple in structure, efficient, convenient, safe, be mainly used in the following compact internal combustion engine of 250CC.
Description of drawings
Fig. 1 is mechanical construction drawing of the present invention (a kind of typical mounting means);
Fig. 2 is starting and a generating kind of drive conversion schematic diagram between motor shaft shown in Figure 1 and the engine shaft.
Embodiment
Fig. 1 illustrates, the present invention includes the starter toothed wheel 2 that is installed on the engine shaft 7, starter toothed wheel 2 is installed on the engine shaft 7 through first unilateral bearing 5, the gear 4 that initiatively generates electricity is installed on the engine shaft 7 through second unilateral bearing 6, and first unilateral bearing 5 is opposite with the installation direction of second unilateral bearing 6; Also has brushless electric machine, initiatively starter toothed wheel 1 and generating gear 3 are installed on the brushless electric machine axle 8, active starter toothed wheel 1 and starter toothed wheel 2 engaged transmission, initiatively the number of teeth of starter toothed wheel 1 is greater than the number of teeth of starter toothed wheel 2, initiatively generate electricity gear 4 and generating gear 3 engaged transmission, the number of teeth of the gear 4 that initiatively generates electricity is less than the number of teeth of the gear 3 that generates electricity.Brushless electric machine is three-phase brushless magneto or direct current permanent magnet motor.
Below in conjunction with Fig. 2 starting and two kinds of working methods conversion of generating electricity are done further and to be specified:
Setting brushless electric machine axle 8 is the N2 axle, and engine shaft 7 is the N1 axle, and initiatively starter toothed wheel 1 is S1, and starter toothed wheel 2 is S2, and generating gear 3 is S3, and the gear 4 that initiatively generates electricity is S4 (so that narration).
(S1: S2)＜(S3: S4); The N2 axle is opposite with the direction of rotation of N1 axle.
1, rotated by motor drives N2 axle when ato unit, (S2＜S1), the S2 velocity of rotation is greater than N1 axle velocity of rotation at this moment, and the S2 transmission combines with D1 is unidirectional, and the S2 transmission drives N1 axle, ato unit then by D1 individual event device to drive the S2 transmission by the S1 transmission; In this simultaneously, the N2 axle drive the S3 transmission drive the S4 transmission to opposite spin (S4＜S3), but this moment the S4 rotating speed greater than N1 axle rotating speed, under the D2 single effect, N1 separates with S4, S3,4 transmission failure do not influence normal startup.
2, (be generally idling speed, but program is regulated) when the engine start rotating speed surpasses minimum normal running speed, no longer initiatively motor is given in power supply, and motor this moment active rotation no longer is converted to generator.
3, drive the rotation of N1 axle by engine, the N1 axle drives the unidirectional opposite spin of D2, and S4 transmission this moment velocity of rotation is less than N1 axle velocity of rotation, and D2 combines with the S4 transmission, drives the S4 transmission and is rotated counterclockwise, and the S4 transmission drives the S3 transmission, drives the motor generating then; S1 transmission meanwhile drives the S2 transmission, but the S2 rotary speed is lower than N1 axle rotating speed, the unidirectional separation of D1, and S1,2 transmission failure do not influence normal power generation.
