Description
Technical field
The utility model belongs to transmission technology field, and in particular to a kind of integrated odd-side stopper protection and rear power taking function
Vehicular transmission.
Background technique
Existing double jackshaft major-minor case speed changers, major-minor case mutual interlocking gear can guarantee: in odd-side shift process, main tank
It cannot shift gears；In gear, main tank can shift gears odd-side.Therefore it when manual shift operation, can prevent because being held not to shift opportunity
It is quasi- and cause auxiliary box synchronizer and its coupling gear premature failure.But after speed changer installs power takeoff additional, odd-side is in neutral gear
When, main tank can not put into gear, and power cannot be normally transmitted to rear power taking system, rear power taking system is caused to can not work normally.
The mechanism of existing secondary box of gearbox locking main tank is arranged referring to Fig. 1 to Fig. 4, including case of transmission 11 in speed change
An odd-side shift fork axle 14, multiple main tank shift fork axles 15 and locking plate 13 in device shell 11, in each main tank shift fork axle 15 respectively
The card slot cooperated with locking plate 13 is offered, is opened up in odd-side shift fork axle 14 there are two the groove reversed with card slot, is distinguished
For the first groove and the second groove, one end far from two grooves is equipped with the auxiliary box cylinder 16 connecting with odd-side shift fork axle 14, described
It is equipped with the auxiliary box cylinder piston 161 being connected with odd-side shift fork axle 14 in auxiliary box cylinder 16 and is set with the interval of auxiliary box cylinder piston 161
The middle position piston 162 set.The locking plate 13 is equipped with erecting bed, the installation with one end that odd-side shift fork axle 14 cooperates
Locking flat spring 12 is equipped between platform and case of transmission 11, described 12 one end of locking flat spring is contacted with erecting bed end face, separately
One end is contacted with the partition wall on case of transmission 11.
Fig. 1 is state when odd-side is in high gear position.The side wall of 16 region II of auxiliary box cylinder is equipped with stop block 163,
Therefore 161 movement travel of auxiliary box cylinder piston is only limitted between auxiliary box cylinder end face and stop block, the region II of auxiliary box cylinder 16
By high gear work 192 air inlet of gas circuit, the piston 161 of auxiliary box cylinder 16 is located at the left terminal location of cylinder stroke, at this time odd-side
The second groove in shift fork axle 14 close to auxiliary box cylinder 161 is aligned with locking plate 13, work of the locking plate 13 in locking flat spring 12
It is moved down under, on the groove for abutting against odd-side shift fork axle 14.Under this state, main tank shift fork axle 15 is not constrained by locking plate,
Any one shift fork axle can move axially operation of putting into gear.
Fig. 2 is state when odd-side is shifted gears.The region I of auxiliary box cylinder 16 passes through low gear work 193 air inlet of gas circuit, odd-side gas
The cylinder piston 161 is in the medium position of auxiliary box cylinder 16, the boss between 14 first groove of odd-side shift fork axle and the second groove at this time
The active force of locking flat spring 12 is overcome to jack up locking plate 13, locking plate enters the groove of main tank shift fork axle 15, so that main tank is dialled
Fork shaft 15 cannot move axially, so that main tank first hangs up gear and causes auxiliary box synchronizer too early during effectivelying prevent odd-side to put into gear
Failure.
Fig. 3 is state when odd-side is in low gear position.The region I of auxiliary box cylinder 16 continues air inlet, auxiliary box cylinder 16
Piston 161 is in the right terminal location of stroke of cylinder, and the first groove of odd-side shift fork axle 14 is aligned with locking plate 13 at this time, locking plate
13 move down under the action of locking flat spring 12, on the groove for abutting against odd-side shift fork axle 14.Under this state, main tank shift fork
Axis 15 is not constrained by locking plate, any one shift fork axle can move axially operation of putting into gear.
State when Fig. 4 is the speed changer trial progress force taking of parking operation for installing mutual interlocking gear additional.Auxiliary box synchronizer is necessary
Behind middle position, the region III air inlet of auxiliary box cylinder 16, auxiliary box cylinder piston 161 shifts middle position by middle position piston 162, the
Boss between one groove and the second groove is abutted with locking plate 13.And under this situation, main tank shift fork axle 15 is locked up plate 13
Constrain immovable, thus speed changer cannot hang up gear.Therefore when installation power takeoff, this lockable mechanism cannot be used.
Summary of the invention
The utility model aim is overcome the deficiencies in the prior art, and propose a kind of integrated odd-side stopper protection and after
The vehicular transmission of power taking function solves and causes auxiliary box synchronizer and its coupling gear mistake due to being not allowed because holding to shift opportunity
The problem of early failure, to transmission belt power takeoff and without power takeoff the case where, are applicable in, and improve the applicability of speed changer.
