Description
Technical field
The utility model relates to automobile gearbox, is specially the medium-sized six gear vehicle gearboxes of a kind of large speed ratio.
Background technique
Current six shift transmissions, two jack shaft not tape synchronizer or the pin-type synchronizer of basic employing in structure, two jack shaft is tape synchronizer shift of transmission difficulty not, and high to the skill requirement of operator, pin-type synchronizer axial dimension is large, lock pin is easily broken, lock ring type list conical surface synchronizer capacity is little, and acceptor center is apart from restriction, and first speed speed ratio is little, gear quantity is few, is not suitable with the demand of the multiple speed ratio of various road conditions.
Summary of the invention
There is the less problem being not suitable with various road conditions demand of ratio coverage in order to solve existing six shift transmissions by structural limitations in the utility model, provides the medium-sized six gear vehicle gearboxes of a kind of large speed ratio.
The utility model adopts following technological scheme to realize: the medium-sized six gear vehicle gearboxes of large speed ratio, comprise main tank output shaft, the right side of main tank output shaft is provided with odd-side, main tank output shaft is connected with the odd-side low gear gear being positioned at odd-side, the right-hand member cover of main tank output shaft has auxiliary box output shaft, on auxiliary box output shaft, cover has odd-side high gear gear, and the left end of auxiliary box output shaft is provided with the tooth cover horizontally slipped thereon, tooth cover top is provided with the shift fork be through on fork shaft, fork shaft right-hand member is connected with manipulating cylinder, jack shaft in parallel is provided with below auxiliary box output shaft, jack shaft is provided with the countershaft-gear with odd-side low gear gear and odd-side high gear gears meshing.
When not needing to increase transmission gear ratio, tooth cover is connected with the conical ring of odd-side low gear gear by manipulating cylinder shift fork, and now, main tank output shaft drives odd-side low gear pinion rotation, and then drives tooth cover and auxiliary box output shaft to rotate, and realizes steadily exporting; When needs increase transmission gear ratio, tooth cover is connected with the conical ring of odd-side high gear gear by manipulating cylinder shift fork, now, main tank output shaft drives odd-side low gear pinion rotation, and then drive the rotation of countershaft-gear, odd-side high gear gear, tooth cover and auxiliary box output shaft, ratio coverage is double, overcomes existing six shift transmissions and there is the less problem being not suitable with various road conditions demand of ratio coverage by structural limitations.
The utility model reasonable in design is reliable, first speed speed ratio is large, realize multi-gear transmission, the requirement of various light medium-duty truck, engineering truck, motor bus and the special car that engine power is 125-140 horsepower section can be met, there is simple, the easy to operate and advantage that cost is low of structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-main tank output shaft, 2-odd-side, 3-odd-side low gear gear, 4-auxiliary box output shaft, 5-odd-side high gear gear, 6-tooth cover, 7-fork shaft, 8-shift fork, 9-manipulating cylinder, 10-jack shaft, 11-countershaft-gear.
