In above-mentioned two clutch gearboxes, described clutch is: on the left side of intermediate transmission combination tooth, offer spline, the right side of center tooth is provided with the spline tooth mating with spline, between the left side of center tooth and jackshaft left end bearing, be provided with by controlling the flexible back-moving spring of driving lever control, back-moving spring is fixedly connected with jackshaft left end bearing respectively with on the left of center tooth, and the control spring contraction of control driving lever or stretching, extension push spline grafting by center tooth right side and fix or separation.
In above-mentioned two clutch gearboxes, described intermediate transmission combination tooth is: gear one is fixedly connected with jackshaft, on the axle sleeve on gear one right side, is fixed with gear two, gear one and gear two concentric settings.
In above-mentioned two clutch gearboxes, the one grade of gear that comprises concentric setting and the intermediate gear of described driving tooth are integrally formed, and the movement of fork controls driving tooth makes one grade of gear and gear one engaged transmission or makes intermediate gear and gear two engaged transmission or make driving tooth and intermediate transmission combination tooth separates.
In above-mentioned two clutch gearboxes, the reverse gear driving tooth that has been connected with a joggle of the intermediate gear in described driving tooth, described reverse gear driving tooth is moved with intermediate transmission combination tooth engaged transmission or is separated by fork controls.
The utility model compared to existing technology outstanding and useful technique effect is:
1, the utility model is applicable on mini-size tillage machine, has improved the safety coefficient of mini-size tillage machine, makes to adopt the mini-size tillage machine of this gear-box to use safer, reliable.
2, of the present utility model pair of clutch gearbox, realizes power conduction without engage a gear and separates, and easy to operate, in work, realizing is that pine stops, and has reached good result of use.
3, structural design novelty of the present utility model, practical.
Accompanying drawing explanation
Fig. 1 is structure principle chart of the present utility model.
Fig. 2 is partial structurtes enlarged diagram of the present utility model.
Fig. 3 is structure principle chart of the present utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-3:
Two clutch gearboxes, comprise casing 1, described casing is provided with power shaft 2, power shaft outside casing is provided with driving wheel 3, it is characterized in that: in described casing, be provided with jackshaft 4, on jackshaft, be fixed with intermediate transmission combination tooth 5, described power shaft is provided with driving tooth 6, driving tooth is moved with intermediate transmission combination tooth engaged transmission or is separated by fork controls, on described jackshaft, slidably connect the center tooth 7 of transmission output shaft 8, described center tooth is linked or separates with intermediate transmission combination tooth by clutch control.
Described clutch is: on the left side of intermediate transmission combination tooth, offer spline 9, the right side of center tooth is provided with the spline tooth 10 mating with spline, between the left side of center tooth and jackshaft left end bearing 11, be provided with by controlling the flexible back-moving spring 12 of driving lever control, back-moving spring is fixedly connected with jackshaft left end bearing 11 respectively with on the left of center tooth, and the control spring contraction of control driving lever or stretching, extension push spline grafting by center tooth right side and fix or separation.
Described intermediate transmission combination tooth is: gear 1 is fixedly connected with jackshaft, on the axle sleeve 14 on gear one right side, is fixed with gear 2 15, gear one and gear two concentric settings.
The one grade of gear 60 that comprises concentric setting and the intermediate gear 61 of described driving tooth 6 are integrally formed, and the movement of fork controls driving tooth makes one grade of gear and gear one engaged transmission or makes intermediate gear and gear two engaged transmission or make driving tooth 6 and intermediate transmission combination tooth separates.
