Description
The utility model relates to the motorcycle gasoline engine electric starter, particularly a kind of cam type overpass clutch electric starter of and motorcycle gasoline engine magnetogenerator adapted.
The principle of available technology adopting free wheel device is made the motorcycle electric starter and is had the accuracy of manufacturing height, the complex structure defective, and escaped to eliminate gradually owing to when using want consumption of engine power.Though centrifugal electric starter is simple in structure, it starts by driving magnetogenerator by the open clutch friction plate of rotary centrifugal force, and friction mechanism resets by extension spring, exists poor reliability, often the normal deficiency of booster magneto.In addition, the motorcycle electric starter of prior art mostly is outlet structure greatly, promptly increase in the outside of magnetogenerator friction disk and can with the mechanism of this friction disk clutch.This structure exist take outer space big, must be to the problem of original shroud structure correct.
The purpose of this utility model be to provide a kind of can make magnetogenerator simple in structure, compact, as to make motorcycle gasoline engine start rapidly, reliable, not only can do built-in installation but also can make the cam type overpass clutch electric starter of external installation.
Above-mentioned purpose of the present utility model is to realize by such technological scheme, it is a kind of cam type overpass clutch electric starter, comprise driving gear or chain, starter receiver or sprocket wheel, driving gear or chain are given starter receiver or sprocket wheel with the transmission of power of actuating motor, it is characterized in that: on the bent axle that starter receiver is installed at one end with magneto rotor is connected, cam by its driven rotary is installed on it, be with floating disc on the cam, float on the floating disc be equipped with can by cam in rotation radially extrapolation or in push away, and can automatically reset and be close to the roller or the ball of cam working face; Device drives bent axle by the roller of radially being extrapolated or ball and the fixing follower disk frictional engagement of petrol engine magneto rotor and rotates, or by the roller that inwardly pushed away by the footpath or ball directly and the bent axle frictional engagement drive its rotation.
Said structure of the present utility model can further specify by the embodiment that accompanying drawing provides.
The utility model has the following drawings:
Accompanying drawing 1 cuts open schematic representation for the utility model embodiment 1 structure side;
Accompanying drawing 2 is that the A of accompanying drawing 1 is to schematic representation;
Accompanying drawing 3 cuts open schematic representation for the utility model embodiment 2 structure side;
Accompanying drawing 4 is that the B of accompanying drawing 3 is to schematic representation.
Referring to accompanying drawing: the cam type overpass clutch electric starter among the figure, comprise driving gear or chain 12, starter receiver or sprocket wheel 8, driving gear or chain are given starter receiver or sprocket wheel with the transmission of power of actuating motor, it is characterized in that: starter receiver or sprocket wheel 8 are installed on the bent axle 10 that at one end is connected with magneto rotor, cam 9 by its driven rotary is installed on it, be with floating disc 7 on the cam, float on the floating disc be equipped with can by cam in rotation radially extrapolation or in push away, and can automatically reset and be close to the roller or the ball 11 of cam working face; Device drives bent axle by the roller of radially being extrapolated or ball 11 and fixing follower disk 4 frictional engagement of petrol engine magnetogenerator 3 rotors and rotates, or by the roller that inwardly pushed away by the footpath or ball directly and the bent axle frictional engagement drive its rotation.
Referring to accompanying drawing 1,2, in the present embodiment, be enclosed within on the bent axle after cam 9a and sprocket wheel are fixing, floating disc 7a is enclosed within on the cam, has notched chimb on it, the number of breach is identical with the chimb of cam and corresponding, and floating in each breach is equipped with ball or roller 11, and a pair of reed 6 that ball or roller are resetted is installed in the outer of breach; The outside of floating disc has annular groove, is installed in damping jump ring card 2 on the casing 1 in poor.
Cam 9a in the accompanying drawing can be for biconvex limit formula cam or many chimbs formula cam, as the equilateral triangle cam; Each salient angle has one and puts the arc back of the body or the straight back of the body of transition gradually to height by low spot.
Referring to accompanying drawing 3,4, in the present embodiment, cam 9b be ring-type convex formula etc. bilateral or etc. polygon cam, floating disc 7b is positioned at cam and is enclosed within on the bent axle, have the breach identical and corresponding with the cam chimb on the floating disc with number, float in each breach ball or roller 11 are installed, a pair of reed 6 that ball or roller are resetted is installed on the interior edge of breach; Be installed with jump ring ring 13 outsides on the floating disc 7a and have annular groove, be installed in damping jump ring 2 on the casing 1 be stuck in poor in.In the present embodiment, be added with fixing with it protection lining on the bent axle 10, drive crankshaft rotating after the frictional engagement with it by ball or roller 11.
Among above-mentioned two embodiments, baffle plate 5 is stamped in floating disc 7 and cam 9 tops.The described device of two embodiments both can be built-in also can be external, when external, be installed in the left cap of motor.
The working procedure of the foregoing description 1 is such, actuating motor 1 drives by chain 12 and starts sprocket wheel 8 rotations, cam 9a rotates with sprocket wheel 8, and floating disc 7a is under the effect of damping jump ring 2, produce staticly relatively, make cam 9a be very easy to outwards to promote reliably ball or roller 11, and make its outer with and the inner edge of the fixing follower disk 4 of petrol engine magneto rotor rub and combine, drive bent axle 10 and rotate, thereby make motorcycle engine work.After the engine operation, because the speed of its rotation is much larger than the speed of cam rotation, this speed official post ball or roller 11 fall behind and are positioned at the lower of cam, behind the actuating motor power supply that breaks, automatically reset under the effect of ball or roller 11 springs 6.
The working procedure of the foregoing description 2 is such: actuating motor 1 drives by chain 12 and starts sprocket wheel 8 rotations, cam 9b rotates with sprocket wheel 8, and floating disc 7b is under the effect of jump ring ring 13 and damping jump ring 2, produce static relatively, make cam 9b be very easy to inwardly promote reliably ball or roller 11, edge drives its rotation with bent axle 10 frictional engagement in it and make, thereby makes motorcycle engine work.After the engine operation, because the speed of its rotation is much larger than the speed of cam rotation, this speed official post ball or roller 11 fall behind and are positioned at the lower of cam, behind the actuating motor power supply that breaks, automatically reset under the effect of ball or roller 11 springs 6.
The utility model is owing to the remarkable advantage that described structure produces is: simple in structure, compact, and peace Dress does not change the contour structures of motorcycle engine, starts quick, reliable.
