Abstract

The utility model relates to a small-sized general gasoline engine starting device, which comprises a shifting fork device, a starting wheel, a plane volute spring, an outer housing, a stay cord and a stay cord handle, wherein the shifting fork device comprises a gland, a shifting fork, a spring, a torsional spring, a shifting fork shaft fixed on the starting wheel and an outer housing fixed on a gasoline engine box body, the gland is in a bowl shape and is provided with a rectangular opening, and a boss is arranged on the starting wheel at a position corresponding to the opening on the gland; the shifting fork and the starting wheel are in arc clearance fit. Simple structure, safety and reliability.

Description

A kind of small utility gasoline engine starting arrangement

(1) technical field

The utility model relates to a kind of small utility gasoline engine starting arrangement.

(2) background technique

At present, the starting arrangement of mini four-stroke general gasoline engines mainly is to start the cup transmission by being fixed on movable shift fork on the boot disk, driving, because shift fork is the cantilever working state, when starting, impulsive torque is bigger, causes that shift fork fractures, and causes starting arrangement to lose efficacy.

(3) summary of the invention

In order to overcome above-mentioned defective, the utility model provides a kind of small utility gasoline engine starting arrangement, can improve the reliability of gasoline starting.

The technical scheme in the invention for solving the technical problem is: a kind of small utility gasoline engine starting arrangement, comprise shifting fork device, driving wheel, plane vortex ring spring, outer casing, stay cord, stay cord handle, described shifting fork device comprises gland, shift fork, spring, torsion spring, is fixed on the declutch shift shaft on the described driving wheel, be fixed on the outer casing on the petrol engine casing, it is characterized in that: described gland is bowl shape, have rectangular linchpin mouthful, on the described driving wheel with described gland on linchpin mouth corresponding position boss is arranged; Described shift fork has 2-3 spare; Described shift fork is that arc-shaped gaps cooperates with described driving wheel.

The beneficial effects of the utility model are simple in structure, and are safe and reliable.

(4) description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the axonometric drawing of starting arrangement

Among the figure: 1, outer casing, 2, driving wheel, 3, plane vortex ring spring, 4, stay cord, 5, the stay cord handle, 6, bent axle, 7, gland, 8, shift fork, 9, spring, 10, torsion spring, 11, declutch shift shaft, 12, linchpin mouthful.

(5) embodiment

Embodiment:

In Fig. 1, gland 7 is bowl shape, at excircle rectangular linchpin mouth 12 is arranged, an end face has boss on driving wheel 2, and declutch shift shaft 11 is fixed on the driving wheel 2, and shift fork 8 has 2, the endoporus of shift fork 8 and declutch shift shaft 11 Spielpassung, the outside of shift fork 8 cooperates for arc-shaped gaps with driving wheel 2.

Driving wheel 2 is installed on the outer casing 1 by plane vortex ring spring 3, shifting fork device is installed in the declutch shift shaft 11 on the driving wheel 2, shift fork 8 can rotate around declutch shift shaft 11, make the head of shift fork 8 scalable outside gland 7, in, when driving wheel 2 being rotated, by gland 7 and driving wheel 2 rotary centrifugal forces with stay cord handle 5 pulling stay cords 4, the outside that makes the head of shift fork 8 stretch out gland 7, the starting cup that drive links to each other with gasoline engine crank rotates, and bent axle rotates thereupon, realizes start-up course.

Claims

1, a kind of small utility gasoline engine starting arrangement, comprise shifting fork device, driving wheel, plane vortex ring spring, outer casing, stay cord, stay cord handle, described shifting fork device comprises gland, shift fork, spring, torsion spring, is fixed on the declutch shift shaft on the described driving wheel, be fixed on the outer casing on the petrol engine casing, it is characterized in that: described gland is bowl shape, have rectangular linchpin mouthful, on the described driving wheel with described gland on linchpin mouth corresponding position boss is arranged.

2, a kind of small utility gasoline engine starting arrangement according to claim 1, it is characterized in that: described shift fork has 2-3 spare.
