Description
Technical field
The utility model relates to gearbox operation system, is specially a kind of many gears commercial car speed changer major-minor case mutual interlocking gear.
Background technique
Along with the fast development of modern logistics industry and domestic expressway construction, the fuel economy that many gears commercial car speed changer brings to car load is quite obvious, and driver is when handling the gearshift of many gear speed transmissions, can because be difficult to the gearshift opportunity accurately grasping main tank and scope gear odd-side, the synchronizer of damage scope gear odd-side, cause TRANS PROGRAM, affect the normal operation of car load.Domestic many gear speed transmissions do not have major-minor case mutual interlocking gear mostly, though have a mutual interlocking gear can not protect auxiliary box synchronizer completely, cause scope to keep off auxiliary box synchronizer rate of fault very high.
Summary of the invention
The utility model, in order to there is fragile synchronizer when solving existing shift of transmission and then cause the problem of TRANS PROGRAM, provides a kind of many gears commercial car speed changer major-minor case mutual interlocking gear.
The utility model adopts following technological scheme to realize: many gears commercial car speed changer major-minor case mutual interlocking gear, comprise main tank housing, main tank shift rod and odd-side shift rod, all slot is had on front side of right part on main tank shift rod, odd-side shift rod left part has the ring-type draw-in groove corresponding with slot position, main tank housing is fixed with the central pin shaft between main tank shift rod and odd-side shift rod, in central pin shaft, cover has with it for the center of circle is rotated and the interlock board be positioned on front side of main tank shift rod and odd-side shift rod, the left side of interlock board is provided with interlocking blocks, the right side of interlock board is provided with interlocking pressing plate, interlock board top leading portion is fixed with column bayonet lock, column bayonet lock front is provided with plug screw, goring push spring is provided with between plug screw and column bayonet lock.
During operation, after the gearshift of scope gear odd-side puts in place, interlock board top is inserted in the ring-type draw-in groove of odd-side shift rod under the action of the spring, and interlock board bottom is in main tank shift rod front, and main tank can carry out gear shift operation; When odd-side is in shift process, interlock board top is positioned at outside the ring-type draw-in groove of odd-side shift rod, and interlock board bottom is inserted in the slot of main tank shift rod, and main tank can not carry out gear shift operation, realizes latch functions; After odd-side gearshift puts in place, interlock board top is inserted in the ring-type draw-in groove of odd-side shift rod, and interlock board bottom is positioned at main tank shift rod front, and main tank can carry out gear shift operation, and main tank unlocks; When main tank is not in neutral, interlock board bottom is positioned at outside main tank shift rod slot, and interlock board top is inserted in the ring-type draw-in groove of odd-side, and odd-side can not carry out gear shift operation, realizes latch functions.There is fragile synchronizer when overcoming existing shift of transmission and then cause the problem of TRANS PROGRAM.
The utility model reasonable in design is reliable, under realizing any gear shift operation situation, to the general protection of scope gear auxiliary box synchronizer, has simple, the easy to operate and advantage that cost is low of structure.
