Abstract

The utility model provides a random gear starting horizontal engine for a motorcycle. A crank shaft 2 is provided with a driving tooth 1, and a main shaft 6 is provided with a clutch compressing disc 12, a clutch driven disc 11 and a clutch outer cover 4; the clutch outer cover 4 is provided with a clutch driven tooth 3, and the clutch driven tooth 3 is meshed with the driving tooth 1; a starting shaft 15 extends into a right crankcase body 19 through a right crankcase cover 20. The structural characters of the random gear starting horizontal engine for a motorcycle are that: the right end of a countershaft 13 is movably sheathed with a gap-bridge tooth 10, and the gap-bridge tooth 10 is meshed with a starting gearing 16 which is movably sheathed on the starting shaft 15; the main shaft 6 is movably sheathed with a spline tooth 5, the spline tooth 5 is connected with the clutch outer cover 4 by a spline groove, and the spline tooth 5 is meshed with the gap-bridge tooth 10. The random gear starting horizontal engine for a motorcycle can restart without slipping back to neutral position when the engine conducts flameout, so the horizontal engine started at arbitrary gear for a motorcycle is labor-saving and convenient to be used.

Description

Motorcycle is shelves starting horizontal engine arbitrarily

One, technical field:

The utility model relates to a kind of motor, especially can be at the motorcycle horizontal engine of any shelves starting.

Two, background technique:

At present, the rearmounted manual clutch horizontal engine of the little discharge capacity of 50～150ml uses quite universal on riding type car, beam bending bicycle and tricycle, during this engine start, rotate by 1 grade of tooth that the free gear on the countershaft drives on the main shaft by the starter receiver on the starting shaft, 1 grade of moving main shaft of cingulum rotates, the driven gear that main shaft drives on the clutch housing rotates, and the driving gear that driven gear drives on the bent axle again rotates, thereby pilots engine.But must fall back on neutral gear earlier in the time of will resetting after this Engine Series is flame-out, promptly make 1 grade of tooth and the engagement of the free gear on the countershaft on the main shaft again, because the restriction of major and minor axle existing structure, need when moving back grade vehicle is moved forward and backward conveniently to move back shelves, this has brought great inconvenience for the user in actual use, and motor tricycle user particularly is because the deadweight of tricycle itself is very big, the user moves forward and backward very effort, uses very inconvenient.

Three, model utility content:

The purpose of this utility model provides a kind of motorcycle shelves starting horizontal engine arbitrarily, solve in the time of to reset after present motorcycle horizontal engine stops working and to fall back on neutral gear earlier, then need vehicle is moved forward and backward in order to make motor fall back on neutral gear, use the problem of effort, inconvenience.

The technical solution of the utility model is: a kind of motorcycle is shelves starting horizontal engine arbitrarily, bent axle is arranged in crankcase, main shaft, countershaft and startup axle, wherein on the bent axle driving tooth is arranged, clutch compressing disc is arranged on the main shaft, clutch driven plate and clutch housing, the clutch driven tooth is installed on the clutch housing, clutch driven tooth and driving tooth engagement, the startup axle passes right crankcase cover and stretches into right crankcase, it is characterized in that: the right-hand member kink of countershaft has the gap bridge tooth, gap bridge tooth and kink are in the starter receiver engagement that starts on the axle, kink has spline tooth on the main shaft, and spline tooth links together by spline and clutch housing, spline tooth and the engagement of gap bridge tooth.

After any shelves are flame-out, to reset when motor in the utility model, at this moment main, also be in the tooth engagement of certain gear between the countershaft, clutch compressing disc is separated with clutch driven plate, rotate and start axle, the starter receiver that starts on the axle rotates by the spline tooth on the moving main shaft of the gap bridge cingulum on the countershaft, spline tooth links together by spline and clutch housing, therefore spline tooth drives the rotation of clutch driven tooth, the clutch driven tooth drives bent axle by driving tooth again and rotates, thereby realize starting, because spline tooth, gap bridge tooth sky respectively is enclosed within the master, on the countershaft, so when starting, main, countershaft is not with spline tooth, the gap bridge tooth rotates synchronously, thereby has realized resetting at any shelves.

The utility model has the advantages that: need not fall back on neutral gear behind the engine misses earlier and just can reset, use more laborsaving, convenient.

Four, description of drawings:

Fig. 1 is a structural representation of the present utility model.

Five, embodiment:

The meaning of each label is in Fig. 1: 1 driving tooth, 2 bent axles, 3 driven tooth, 4 clutch housings, 5 spline tooths, 6 main shafts, 7 clutch separation cams, 8 push rods, 9 clutch release bearings, 10 gap bridge teeth, 11 clutch driven plates, 12 clutch compressing discs, 13 countershafts, 14 ratchet guide plates, 15 start axle, 16 starter receivers, 17 ratchets, 18 ratchet springs, 19 right bent axle bodies, 20 right crankcase covers, 21 ratchet spring seats.

As shown in Figure 1: driving tooth 1 is arranged on the bent axle 2 in the utility model, clutch compressing disc 12 is arranged on the main shaft 6, clutch driven plate 11 and clutch housing 4, clutch driven tooth 3 is installed on the clutch housing 4, clutch driven tooth 3 and driving tooth 1 engagement, startup axle 15 passes right crankcase cover 20 and stretches into right crankcase 19, its structure characteristic is: the right-hand member kink of countershaft 13 has gap bridge tooth 10, gap bridge tooth 10 meshes at the starter receiver 16 that starts on the axle 15 with kink, kink has spline tooth 5 on the main shaft 6, spline tooth 5 links together by spline and clutch housing 4, spline tooth 5 and 10 engagements of gap bridge tooth.

As can be seen from Figure 1: be set with ratchet 17 with spline on startup axle 15, be provided with ratchet spring 18 between ratchet 17 and the ratchet spring seat 21, there is ratchet guide plate 14 top of ratchet 17, ratchet guide plate 14 and ratchet 17 engagements.

Working principle: in the time of will resetting after motor is flame-out on gear, earlier with clutch brake handle under the hand, 7 rotations of clutch separation cam promote push rod 8 and push down clutch release bearing 9, and clutch driven plate 11 and clutch compressing disc 12 are separated; At this moment, pin is stepped on starting bar and is made 15 rotations of startup axle, drives ratchet 17 and separates from ratchet guide plate 14, and ratchet 17 is sliding on startup axle 15 under the effect and starter receiver 16 engagements at ratchet spring 18, drives starter receiver 16 and rotates synchronously with startup axle 15; Starter receiver 16 drives gap bridge tooth 10 rotations with its engagement, gap bridge tooth 10 drives spline tooth 5 rotations with its engagement, because the clutch driven tooth 3 on spline tooth 5 and the clutch housing 4 has been connected into an integral body of rotating synchronously, and this integral body is that sky is enclosed within on the main shaft 6, so at this moment clutch driven tooth 3 is rotated synchronously with spline tooth 5, and major and minor axle does not at this moment rotate, clutch driven tooth 3 drives driving tooth 1 rotation with its engagement, driving tooth 1 is fixed on the bent axle 2, thereby bent axle 2 is driven the starting that realizes motorcycle.
