Abstract
The spiral telescopic apparatuse for transmission rod to manually start engine of motor-driven vehicles can realize automatic axial movement and return of transmission rod. Its end face has opening with symmetric inclined guide surfaces. The obstructing sleeve supported by stop spring can prevent drive pin from rotating, so sprial axle sleeve drives drive pin in slot to push transmission rod to move axially, thus making the drive part at front end of transmission rod match with corresponding part of main shaft of engine.
Description
A kind of spiral telescopic apparatus of transmission rod that is used for the hand starting motor vehicle engine.
On microtractor, use a kind of known hand-operated starter by one-level gear pair speedup.Before piloting engine, need, make transmission lateral pin on the coupled drive link with the starting dog combination on the engine spindle head with hand propulsion driven gear movably.So this starter is loosely organized, it is big to take up room, and inconvenience is installed and operation.
The objective of the invention is, needs according to the hand starting motor vehicle engine, design a kind of simple in structure, easily make, reliable performance, it is little to take up room, be convenient to use, but the drive link automatic axial moves during rotation, and the driving component (or similar functions part) that makes the head installation is with the starting dog on the engine spindle (or identical function parts) combination, and the starting back is " spiral telescopic apparatus of transmission rod " of separation automatically.
The present invention is achieved in that is equipped with a drive link that moves the driving component of the parts interlock of installing with the engine spindle head or engagement through axle.Being sleeved on the other end of drive link has one section symmetrical spiral notch, and one by the spiral sleeve that is fixed on the bearing block support on the frame.Pass the pin-and-hole on the drive link, load exposes the drive pin that two ends has stopping table between two symmetrical spiral notches.One is with the shoulder supporting of spiral chute mouth termination by screw axis, and one is stuck in and makes drive pin lean against the return helical spring of one in spiral notch on the drive pin stopping table.Be sleeved on the spiral sleeve, the restriction drive pin drives drive link and rotates with spiral sleeve, with leaning against the bearing support end face, initial elastic force is greater than the retaining helical spring supporting of return helical spring elastic force, by the guide mechanism restrictive axial mobile position that is fixed on the bearing support, the termination has and a pair of or several a side is had the guiding surface of identical lift angle direction, the interference cover of the gap of the clamping drive pin of position symmetric arrangement.Rotating screw axle sleeve, drive pin are subjected to disturb cover gap clamping restriction not rotate thereupon, are promoted to make the drive link axial slip by the spiral notch.When the driving component that moves to its head during with the corresponding parts joining on the engine spindle, the effect that the spiral notch can utilize the restriction drive link of joining to rotate continues to promote drive link and moves axially, until driving component with the complete combination of corresponding parts on the main shaft.After the engine start, under the helical spring effect of return, drive link is got back to the origin-location of spiral notch.Driving component as the drive link head bumps with the corresponding parts top on the main tapping, and drive pin can disturb cover to shift out end face by the compression of gap inclined-plane, makes driving component turn an angle the back with corresponding combination on the main shaft with drive link.
The guide mechanism of spiral telescopic apparatus of transmission rod is the bent plate that curves the right angle by, be screwed on bearing support on one side, one side is parallel to disturbs cover and is processed with the straight trough mouth that is used for guide and limit, is fixed on the screw cap head that disturbs on the jacket wall and is embedded in formation in the notch.
Spiral telescopic apparatus of transmission rod of the present invention, the interference cover that has adopted the termination to have the gap of symmetric arrangement to support by the retaining helical spring, the restriction drive link rotates, make the spiral notch of spiral sleeve can be by carrying on a shoulder pole between notch, promote drive link by the driving pin of return helical spring supporting and move axially, be directed at the driving component that is loaded on the drive link head with the corresponding parts combination on the engine spindle.Be characterized in that simple in structure, it is little to take up room, adaptability is strong, easily makes, and is convenient to install combination and convenient separation operation automatically.
Accompanying drawing 1 of the present invention is embodiment's a structural member assembly view.
Spiral telescopic apparatus of transmission rod, its structure is, the drive link (7) that driving pin (8) radially are housed, insert in the axial bore of the spiral sleeve (5) that is supported by the bearing support (1) that is fixed on the frame its other end, the pin-and-hole of drive pin (4) by drive link (7) penetrates one section symmetrical spiral notch of spiral sleeve (5) and load therebetween, and exposing the termination has stopping table.Adorn a return helical spring (6) that makes drive pin lean against one in spiral notch between the termination shoulder of stopping table and spiral sleeve (5).Be sleeved on the spiral sleeve (5), the termination has two pairs one sides that the guiding surface of identical lift angle direction is arranged, and all claims to arrange the gap that is used for clamping drive pin (4).By the interference cover (3) of initial elastic force greater than retaining helical spring (2) supporting of return helical spring (6), the angle block of right angle (10) that one section guiding straight trough mouth is arranged that is fixed on the bearing support (1) with screw (11) disturbs on cover (3) wall by being fixed on, the cap head is embedded in the position that moves axially of interior screw (9) the limit interferences cover (3) of notch, rotating screw axle sleeve (5), under the restriction of disturbing cover (3) notch, the spiral notch promotes drive link (7) by drive pin (4) and moves axially, driving pin (8) is ridden on the gap limit of the starting dog on the engine spindle head, and the effect that utilizes its restriction to rotate makes two parts interlocks.After the engine start, make drive link (7) reposition by the elastic force of return helical spring (6).Withstand on the boss of starting dog as driving pin (8), drive pin (4) disturbs cover (3) to shift out end face and rotate a corresponding angle with the joining of starting dog gap by the guiding surface compression.
Claims (2)
1, a kind of spiral telescopic apparatus of transmission rod that is used for the hand starting motor vehicle engine, it constitutes, one is equipped with the drive link that moves the driving component of the parts interlock of installing with the engine spindle head or engagement through axle, be sleeved on the other end of drive link, one section symmetrical spiral notch is arranged, one by the spiral sleeve that is fixed on the bearing block support on the frame, the pin-and-hole load of passing drive link is between two symmetrical spiral notches, exposing two ends has the drive pin of stopping table, a shoulder supporting that is with spiral chute mouth termination by screw axis, one is stuck in and makes drive pin lean against the return helical spring of one in spiral notch on the drive pin stopping table, the invention is characterized in, be sleeved on the spiral sleeve, the restriction drive pin drives drive link and rotates with spiral sleeve, with leaning against the bearing support end face, initial elastic force supports greater than the retaining helical spring of return helical spring elastic force, by the guide mechanism restrictive axes pan position that is fixed on the bearing support, the termination has and a pair of or several a side is had the identical guiding surface of lift angle direction, and the folder of position symmetric arrangement is by the interference cover of the gap of drive pin.
