The specific embodiment
Referring to Fig. 1 to Fig. 3, the bent axle of crank connecting link assembly by bearings in a left side, right crankcase 25, on 21, bent axle 1 is equipped with and primary drive gear 4 bonded assembly centrifugal type automatic clutchs, this power-transfer clutch is as low-speed clutch, outer cover 2 free-running fits of power-transfer clutch are on bent axle 1, primary drive gear 4 splines are connected on the outer cover 2 of this power-transfer clutch, adopt welding also can reach same effect, the driving disc spacing pressing 3 with centrifugal shoe plate of this power-transfer clutch is connected with bent axle 1 spline and with the fastening location of nut, interference fit has free-wheel clutch 5 on the outer cover 2 of power-transfer clutch, free-wheel clutch 5 and driving disc spacing pressing 3 free-running fits with centrifugal shoe plate.Transmission main shaft 7 is supported on the left and right crankcase 25,21.Described transmission main shaft is made up of gear wheel shaft 7 and two geared sleeves 11,12, free-running fit one geared sleeve 12 on the gear wheel shaft 7, free-running fit has another geared sleeve 11 on this geared sleeve 12, the geared sleeve 12 of free-running fit is the intermediate gear cover on the described gear wheel shaft 7, the number of teeth of this intermediate gear cover 12 is less than the number of teeth of another high speed gear cover 11 of free-running fit on this geared sleeve 12 more than the number of teeth of low speed gear axle 7.Gear wheel shaft 7 upper splines connect the outer cover 8 of an elementary driven gear 6 and a middle and high fast centrifugal type automatic clutch, and with ring washer or the fastening location of nut, elementary driven gear 6 and primary drive gear 4 engagements.Be provided with two driving disc spacing pressings 9,10 in the middle and high fast centrifugal type automatic clutch with centrifugal shoe plate, one of them driving disc spacing pressing 9 spline is connected on the intermediate gear cover 12, another driving disc spacing pressing 10 splines are connected on the high speed gear cover 11, the outer cover 8 of two driving disc spacing pressing 9,10 shared power-transfer clutchs, geared sleeve 11 cooperates with right crankcase 21 by bearing.Output countershaft 13 by bearings on left and right crankcase 25,21.This output countershaft 13 is provided with three driven gears, and one of them high speed driven gear 14 is connected with output countershaft 13 splines and meshes with high speed gear cover 11; On the middling speed driven gear 15 free-running fit have free-wheel clutch 16 and with output countershaft 13 free-running fits, these free-wheel clutch 16 splines are connected on the output countershaft 13, middling speed driven gear 15 and 12 engagements of intermediate gear cover; On the low speed driven gear 19 free-running fit have free-wheel clutch 18 and with output countershaft 13 free-running fits, these free-wheel clutch 18 splines are connected on the output countershaft 13, low speed driven gear 19 and 7 engagements of low speed gear axle.The number of teeth of described middling speed driven gear 15 is less than the number of teeth of low speed driven gear 19 more than the number of teeth of high speed driven gear 14.A recoil starter gear that starts for pin is supported on the left and right crankcase 25,21.The pin of this recoil starter gear starts starter receiver 17 of free-running fit on the axle 20, starter receiver 17 and low speed driven gear 19 constant-meshes, the ratchet 22 that spiral cooperates on the pin startup axle 20 is done very with starter receiver 17 by end tooth, and engagement cooperates, the jump ring 23 that starter receiver 17 is limited on the left crankcase 25 is circumferentially located, and the pull back spring 24 that pin starts axle 20 settings is limited in right crankcase 21.
During start the engine, handling actuating lever with pin makes staring torque pass to low speed driven gear 19 by the starter receiver 17 that pin opens on the axle 20, this moment free-wheel clutch 18 with low speed driven gear 19 short circuits, make low speed driven gear 19 form idle running, become the startup carrier gear, low speed driven gear 19 is passed to low speed gear axle 7 with power, and power is passed to bent axle 1 by outer cover 8, the free-wheel clutch 5 of elementary driven gear 6, primary drive gear 4, low-speed clutch, make Piston Compression recoil start the engine.After discharging manipulation, pull back spring 18 makes pin open axle 20 drive ratchets 16 and leaves starter receiver 15.
Engine operation, when the less engine speed of accelerator open degree is low, bent axle 1 drives rotary power outer cover 3 rotations of low-speed clutch by the driving disc spacing pressing 3 with centrifugal shoe plate of low-speed clutch, the outer cover 3 of low-speed clutch rotates by the gear wheel shaft 7 that primary drive gear 4, elementary driven gear 6 drive transmission main shaft, and gear wheel shaft 7 drives output countershafts 13 rotation outputting powers by low speed driven gear 19 through free-wheel clutch 18.This moment is because engine speed is lower, though the outer cover 8 of middle and high fast centrifugal type automatic clutch is with gear wheel shaft 7 rotations, but do not combine with the centrifugal shoe plate of two driving disc spacing pressings 9,10 as yet, middle and high fast centrifugal type automatic clutch is transferring power not, and driving engine is in the low speed turbine stage stage.
Aperture increasing along with throttle, the rotating speed of driving engine improves, when engine speed during in the 3500r/min left and right sides, when just middling speed is the 950r/min left and right sides in conjunction with rotating speed, in, the centrifugal shoe plate of the middling speed driving disc spacing pressing 9 of high-speed centrifugal self-acting clutch combines with outer cover 8, in, the high-speed centrifugal self-acting clutch is started working, so power by the outer cover 8 of power-transfer clutch through middling speed driving disc spacing pressing 9, intermediate gear cover 12 drives middling speed driven gear 15 rotations on the output countershaft 13, and middling speed driven gear 15 is passed to output countershaft 13 with rotary power by free-wheel clutch 16 and directly exported.At this moment, the centrifugal shoe plate of high speed driving disc spacing pressing 10 does not combine with outer cover 8 as yet, transferring power not, and free-wheel clutch 18 is low speed driven gear 19 short circuits, low speed driven gear 19 is around the idle running of output countershaft.Driving engine is in the middling speed level stage.
Along with the aperture of throttle further strengthens, the rotating speed of driving engine further improves, when engine speed during in the 6000r/min left and right sides, when just being the 1300r/min left and right sides in conjunction with rotating speed at a high speed, the centrifugal shoe plate of high speed driving disc spacing pressing 10 combines with outer cover 8, middle and high fast centrifugal type automatic clutch works on, so power is rotated through the high speed driven gear 14 that high speed driving disc spacing pressing 10, high speed gear cover 11 drive on the output countershaft 13 by the outer cover 8 of power-transfer clutch, high speed driven gear 14 is directly exported rotary power by output countershaft 13.At this moment, free-wheel clutch 18 is with low speed driven gear 19 short circuits, and free-wheel clutch 16 is with middling speed driven gear 15 short circuits, and low speed driven gear 19 and middling speed driven gear 15 are all around 13 idle running of output countershaft.Driving engine is in the level stage at a high speed.
Otherwise along with the aperture of throttle reduces gradually, the rotating speed of driving engine reduces gradually, and driving engine is by level stage, middling speed level stage return to the low speed level stage at a high speed.
