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 one grade of tooth that the free gear on the countershaft drives on the main shaft by the starter receiver on the starting shaft, one 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 one 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 and just to reset and vehicle must be moved forward and backward after present motorcycle stops working with horizontal engine, so that the gear of motor returns to neutral gear earlier, thus the problem of use effort, inconvenience.

The purpose of this utility model is achieved through the following technical solutions:

A kind of motorcycle is shelves starting horizontal engine arbitrarily, comprise bent axle, main shaft, countershaft and startup axle, wherein on the bent axle driving tooth is arranged, the gear driving gear is arranged on main shaft and the countershaft, clutch is installed on the main shaft, the clutch driven tooth is installed on the clutch housing, clutch driven tooth and driving tooth engagement, start on the axle starter receiver and ratchet are arranged, the startup axle passes right crankcase cover and stretches into right crankcase, the right-hand member kink of described countershaft has the gap bridge tooth, and should the gap bridge tooth be positioned at the right side wall inboard of right crankcase, and gap bridge tooth and kink are in the starter receiver engagement that starts on the axle, be set with spline tooth on the main shaft, this spline tooth passes the right side wall of right crankcase, inner and gap bridge tooth engagement, and the outer end links together by spline and clutch housing.

Gap bridge tooth and spline tooth all work the moment of torsion of pass a bridge doing in order on will starting spool and are delivered on the clutch driven tooth in the utility model.When motor in that arbitrarily shelves are flame-out will reset the time, 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 return to 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.

The meaning of each label is among the figure: 1 driving tooth, 2 bent axles, 3 clutch 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 starter receiver friction springs, 15 start axle, 16 starter receivers, 17 ratchets, 18 right side walls, 19 right bent axle bodies, 20 right crankcase covers.

Five, embodiment:

As shown in Figure 1: bent axle 2, main shaft 6, countershaft 13 and startup axle 15 are arranged in crankcase, wherein on the bent axle 2 driving tooth 1 is arranged, on main shaft 6 and the countershaft 13 the gear driving gear is arranged, on the main shaft 6 clutch is installed, described gear driving gear is arranged in right crankcase 19, driving tooth 1 and clutch are positioned at the outside of right crankcase 19 right side walls 18, clutch driven tooth 3 is installed on the clutch housing 4, clutch driven tooth 3 and driving tooth 1 engagement, start on the axle 15 starter receiver 16 and ratchet 17 are arranged, startup axle 15 passes right crankcase cover 20 and stretches into right crankcase 19, the right-hand member kink of countershaft 13 has gap bridge tooth 10, and the inboard that should gap bridge tooth 10 be positioned at right crankcase 19 right side walls 18, gap bridge tooth 10 meshes at the starter receiver 16 that starts on the axle 15 with kink, be set with spline tooth 5 on the main shaft 6, this spline tooth 5 passes the right side wall 18 of right crankcase 19, inner and gap bridge tooth 10 meshes, the outer end links together by spline and clutch housing 4, gap bridge tooth 10 by bearings on the right side wall 18 of right crankcase 19.In order to hold gap bridge tooth 10, the section that right crankcase 19 right side walls 18 are used for supports main shaft 6, countershaft 13 and start axle 15 should outwards be moved.

As can be seen from Figure 1: be the helical teeth engagement between described ratchet 17 and the startup axle 15, be wound with starter receiver friction spring 14 on the ratchet 17, one pin of starter receiver friction spring 14 is fixed on right crankcase 19 inwalls, in the startup axle combination of this structure, ratchet 17 places radially take up room little, can guarantee the layout of countershaft 13 and top gear driving gear thereof.

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, driving ratchet 17 rotates, the helical teeth that ratchet 17 starts on the axle 15 in the twisting force lower edge of starter receiver friction spring 14 is starting slip on the axle 15, when sliding into starter receiver 16 engagements, ratchet 17 drives starter receiver 16 and rotates synchronously with startup axle 15; Starter receiver 16 drives gap bridge tooth 10 rotations with its engagement again, 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.
