The utility model is loaded onto locomotive, block with rocking handle and to recoil the one-way shaft right-hand member counterclockwise around to the regulation number of turns, just can realize later on hypergolicing start, no longer hand starting, when locomotive need start, the decompression Joystick should be pulled to the starting position, make control point A and its lock jail on the decompression locking plate, the locomotive of this moment is in decompression state, open throttle subsequently, clutch handle is pulled back counterclockwise, make eccentric openings place and separator levers head end lock jail on clutch handle one end, this moment, clutch handle just can't return, when the pulling clutch handle, because the displacement of clutch handle, the interlocking pin will be pulled back by the interlocking backguy, and itself and operating crank loss of interlocking are controlled.Simultaneously because the effect of clutch disengaging pawl, when the pulling clutch handle, distance between clutch handle and clutch disengaging pawl are axial will be elongated, thereby force the clutching pressure bearing, the pressure transmission ring set, pressure transmission pin and clutch for clutch control pin together are moved to the left, the clutch for clutch control pin is outwards extruded the clutch ball in the clutch hollow shaft, make that the clutch ball is in that clutch hollow shaft and clutch just overlapping axially between both cards are one, the locomotive of this moment is in treats starting state, stir operating crank then counterclockwise backward, because the effect of starting disengaging pawl, the starting clutch cover will be forced to move right when stirring, up to thoroughly separating with the starting clutch gear, after the separation, the starting clutch gear lose the starting clutch cover to it control and unrestricted motion, discharge thereby power spring is out of control, spring shaft, line shaft, power gear, the automatic control timing gear, together with the deceleration built-up gear, starting clutch gear and overdrive clutch gear are all done and are run up, a free wheel device is housed between overdrive clutch gear and connection shaft, its effect is when power spring discharges, it can be an one with overdrive clutch gear and connection shaft card, when the speed on the connection shaft surpasses speed on the overdrive clutch gear, their mutual noninterferences of will turning round separately, therefore the power spring the time is in releasing state, overdrive clutch gear and connection shaft just wedge are that one runs up, because of connection shaft is connected with one heart with the clutch hollow shaft, the locomotive belt pulley just is forced to run up, and the automatic control timing gear on the line shaft drove the counting crop rotation and moved counterclockwise this moment.When the decompression timing pin on the counter wheel contacts with the decompression controlling rod,, thereby make the action of decompression locking plate by decompression control backguy along with running decompression timing pin will force the action of decompression controlling rod; When the decompression Joystick lost the control that A is ordered on the decompression locking plate, because the effect of decompression control spring, the decompression Joystick resetted rapidly, closes decompression and makes locomotive break out starting.

Behind the train starting, the rotating speed on the connection shaft raises gradually, and power spring has discharged, and the overdrive clutch gear just loses the control of free wheel device with connection shaft and staticly do not rerun; Connection shaft drives the crop rotation of deceleration disjunctor chain by chain and turns round counterclockwise, slows down and drive One-way chain wheel by the rough lock bar again after the disjunctor sprocket wheel slows down and do running counterclockwise together with recoiling sprocket wheel under the direct transmission of locomotive belt wheel; Recoil one-way element in the One-way chain wheel aims at hand recoil energy storage and designs, purpose is: recoil one-way shaft when rotating counterclockwise blocking with handle, tooth embedding that starting clutch puts and the mutual wedging of tooth embedding on the starting clutch gear are together rotated and the One-way chain wheel transfixion, only after locomotive operation is normal, when recoiling sprocket wheel and driving it and do running counterclockwise by chain and deceleration disjunctor sprocket wheel, rough lock bar, recoiling guider just can with One-way chain wheel and to recoil the one-way shaft wedge be that one together turns round and realizes recoiling automatically energy storage; This moment, locomotive ran well, One-way chain wheel and recoil one-way shaft are all in counterclockwise running, therefore operating crank is also in the starting position time, the starting clutch cover is in separated state with the tooth embedding of starting clutch gear, the starting clutch gear can't be with recoiling the one-way shaft running, and power spring also can't be realized recoiling; Its belt wheel clutch part; Connection shaft and chain transmission system comprise that recoiling one-way shaft all dallies in the running with locomotive.If unclamp operating crank this moment, because the existence of starting return spring, operating crank resets rapidly, the starting clutch cover has lost the control of operating crank, operation left under the effect of place spring is stretched on the right side, and when the tooth embedding of starting clutch cover combined with the tooth embedding of starting clutch gear, the starting clutch gear just together turned round counterclockwise along with recoiling one-way shaft, thereby through the rear driving of deceleration built-up gear guiding, power gear makes power spring recoil energy storage; Along with the automatic control timing gear on rotation, the line shaft are also turning round, the counting crop rotation is moved clockwise, when power spring takes up, the eccentric movable lug of separating controlling on the counter wheel just in time with separator levers to pressing down an angle, and the head end of separator levers just upwards moves an angle and breaks away from control to clutch handle.Clutch handle reverses rapidly under the effect of interlocking spring and resets, clutching pressure bearing, pressure transmission ring set, pressure transmission pinning, clutch for clutch control pin move to right rapidly under the effect of pressure spring, the clutch ball just falls in the hollow cavity of clutch hollow shaft again, clutch is just being overlapped out of hand with the clutch hollow shaft and is being separated all stop motions of each of starter; And this moment, power spring took up, its active force is divided into two-way by power gear, the deceleration built-up gear of leading up to will make the starting clutch gear clockwise rotate, another road is by the overdrive clutch gear, connection shaft, recoil sprocket wheel are through chain and deceleration disjunctor sprocket wheel, driving the recoil sprocket wheel by the rough lock bar again forces the recoil one-way shaft to rotate counterclockwise, like this, the active force of power spring and reaction force are packed with regard to the tooth that has dropped on starting clutch gear and starting clutch cover, as long as it is not separated that their tooth embeddings of two are bitten, power spring just can't discharge.Want to make power spring to discharge, stir operating crank with regard to necessity, after starter is static, because of the clutch handle reposition, the interlocking backguy is by tightly fluffing, and the pulling force of interlocking pin loss of interlocking backguy sets back under the effect of interlocking spring, stings tightly with operating crank again, make it under the situation of not handling clutch handle, can't make the operating crank action.Such interlocked control has guaranteed that promptly starter misoperation can not occur, has also increased its safety coefficient simultaneously.

Owing to adopted above-mentioned technological scheme, make the utility model that cheap cost and very strong adaptability be arranged, very high safety coefficient and starting performance are also arranged simultaneously.
