Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to Fig. 1, the utility model comprises housing 1 and is installed in housing 1 motor 2 outward, active flywheel 4, belt pulley 5, driven flywheel 12 and driven gear 13, bent axle 3 is installed initiatively and from dynamic crankshaft 11 in housing 1, described active bent axle 3 and be separately installed with initiatively flywheel 4 from the two ends of dynamic crankshaft 11, belt pulley 5, driven flywheel 12 and driven gear 13, motor 2 links to each other with the belt pulley 5 of active bent axle 3 by the vee belt, described active bent axle 3 and from the crank-connecting rod of dynamic crankshaft 11 footpath, driving crank connecting rod 6 and driven crank-connecting rod 10 are arranged fixedly respectively, driving crank connecting rod 6 links to each other by lever 7 with driven crank-connecting rod 10, and the fulcrum 8 of described lever 7 is positioned at the back 2/3-4/5 place of lever 7 and active bent axle 3 tie points.The both sides that are positioned at fulcrum at housing 1 also are separately installed with the lever fixing frame of swinging for truck dead lever 79 all around, from dynamic crankshaft 11, gear 14 is arranged fixedly also, starter motor 15 that be meshed with gear 14 and that start simultaneously with motor 2 is fixedly arranged outside housing 1.Mainly be to prevent from counter-rotating when starting, occurring from dynamic crankshaft 11, at the inertia that adds driven flywheel 12, make from dynamic crankshaft 11 and rotate towards a direction all the time, also be connected with gearbox on the driven gear of the present utility model, this gearbox is respectively arranged with forward gears, reverse gear and neutral gear, and effect has two aspects, one, gear is placed on the neutral gear, make between lever energizing driver and the machinery equipment not connect, not transmission is convenient to lever energizing driver and is started under the situation that does not have load; Two, lever energizing driver is to a direction transmission all the time, and some machinery not only needs just changeing when proper functioning, also needs counter-rotating sometimes, so need use reverse gear.
Referring to Fig. 2, the perpendicular distance of 3 central points of active bent axle of the present utility model and active crankshaft crank connecting rod footpath central point is 2-4 times from the perpendicular distance of 11 central points of dynamic crankshaft and driven crankshaft crank connecting rod footpath central point, motor 2 drives initiatively, and bent axle 3 rotates, driving lever 7 power arms by driving crank connecting rod 6 moves up and down, lever 7 moves up and down, rotating from dynamic crankshaft 11 by driven crank-connecting rod 10 drives, initiatively the crank-connecting rod of bent axle 3 footpath goes to the B point by the A point, perpendicular distance equals the distance that the power arm of lever 7 moves up and down between 2, because power arm is 2-4 times of resistance arm, so the distance that resistance arm moves up and down is the 1/2-4/5 that moves up and down distance of power arm, the distance that resistance arm moves up and down equals to go to the distance that A is ordered from the crank-connecting rod footpath of dynamic crankshaft 11 by the B point, initiatively bent axle 3 turns to the B point by the A point, lever 7 power arms move up, the resistance arm of lever 7 moves down, simultaneously turn to the A point by the B point from dynamic crankshaft 11, the power of motor 2 outputs carries out reinforcing by lever, power after the reinforcing increases several times than the power of former motor 2, depend primarily on the position of the fulcrum 8 of lever, power arm is several times of resistance arm, depend primarily on the position of the fulcrum of lever, the position of balance pivot 8 depends on that again 3 central points of bent axle initiatively and the perpendicular distance of crankshaft crank connecting rod footpath central point initiatively are from 11 central points of dynamic crankshaft and driven crankshaft crank connecting rod several times of perpendicular distance of central point directly.
In Fig. 3, at the fixing steel axle of the power arm of lever 7, a bearing is fixed at the two ends of axle respectively, curved plate is close in the outer ring of bearing, along with lever moves up and down, bearing rolls along the arc track on the steel plate, and the fixing frame of resistance arm also uses the same method fixing, and the effect of lever fixing frame 9 is the swing of truck dead lever left-right and front-back.
