Abstract
The utility model belongs to categories of automobile gearboxes, and particularly relates to an interlocking device of a main-auxiliary box structural gearbox assembly. The interlocking device comprises a main box and an auxiliary box. The main box has multiple gear positions, and the auxiliary box has two gear positions. Through the linkage of the main box and the auxiliary box, main-auxiliary box multiple gear position equal ratio range speed ratio is achieved. The interlocking device is characterized in that the main box gear position switchover is manipulated in a mechanical method, the auxiliary box high-low gear switchover is manipulated to complete in a pneumatic method, an air hole is formed in the middle of an auxiliary box cylinder, a path of air source is led out for manipulating a locking mechanism of a main box control mechanism, the air source air path is closed before gear shifting of the auxiliary box cylinder is not finished, the main box control mechanism is locked, after gear position switchover of the auxiliary box cylinder is finished, the air source air path is unlocked, and thus the main box control mechanism can finish gear shifting. According to the interlocking device, before gear position of an auxiliary box synchronizer is not put into, the main box cannot shift gear, misoperation by human factors is avoided, and the gearbox auxiliary box synchronizer can normally reach the designed service life.
Description
Technical field
The utility model belongs to the automotive transmission class, specifically a kind of interlock of major-minor case structure transmission assembly.
Background technique
The speed changer that heavy truck fills in the most domestic now is the transmission assembly of major-minor case structure, install preposition odd-side or the box back auxiliary box of one 2 gear additional at the main tank of a 4-6 forward gear, the transmission gear figure place is multiplied, realize that by the speed ratio arrangement design many gear casees with better cooperation motor curve, satisfy the needs of power character and fuel-economizing; In order to guarantee continuity that gear is arranged and the travelling comfort of gearshift, wait the general odd-side of major-minor case structure transmission assembly of extreme difference design velocity ratio all with synchronizer; This synchronizer is when theory is calculated, think that main tank is neutral, so it is generally all lower to calculate the rotary inertia of input end, this also is most of major-minor case structure transmission assembly when requiring the odd-side gearshift in operating instruction, and the driver waits for the reason of hanging again neutral a little.But present most transmission assembly all is the driver controls assurance voluntarily, and because the difference of each driver's driving habits, many drivers have just hung up the main tank gear when odd-side also is not suspended to gear fully, even the clutch that come loose, so that auxiliary box synchronizer needs the synchronously rotary inertia that surpasses Theoretical Design far away, cause auxiliary box synchronizer early failue, be significantly less than projected life.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, a kind of interlock of major-minor case structure transmission assembly is provided, guarantee that fundamentally auxiliary box synchronizer is before failing to hang up gear, main tank can not be shifted gears, avoided the misoperation of personal factor, made the secondary box of gearbox synchronizer can normally reach projected life.
The utility model is achieved through the following technical solutions:
A kind of interlock of major-minor case structure transmission assembly, comprise main tank, odd-side, main tank has a plurality of gears, odd-side has two gears, finish the realization of many gears of major-minor case geometric ratio extreme difference speed ratio by the interlock of major-minor case, it is characterized in that: the main tank gear switches to be handled by mechanical type, the switching of odd-side high to low gear is finished by air-operated control, in odd-side cylinder intermediate portion a pore is arranged, draw the lockable mechanism that one road source of the gas is handled the main tank operating mechanism, before the odd-side cylinder is finished gearshift, can not seal this source of the gas gas circuit, locking main tank operating mechanism, after the odd-side cylinder was finished the gear switching, release source of the gas gas circuit made the main tank operating mechanism can finish gearshift.
The lockable mechanism of the utility model main tank operating mechanism is realized by air pressure control interlock spring and the interlocking plunger of pore source of the gas.When odd-side was suspended to gear, gas circuit was unimpeded, and air pressure promotes the lockable mechanism on the main tank operating mechanism, so that main tank can easily be shifted gears; When odd-side in gearshift and when not being suspended to gear, the motion of also failing of the piston in the odd-side cylinder puts in place, at this moment piston so that the pore at cylinder middle part be closed, the gas circuit sealing, lockable mechanism withstands the main tank operating mechanism, so that main tank can not be shifted gears, reaches usage requirement with this.
The utility model fundamentally guaranteed auxiliary box synchronizer before failing to hang up gear, and main tank can not be shifted gears, and had avoided the misoperation of personal factor, made the secondary box of gearbox synchronizer can normally reach projected life.
Description of drawings
Fig. 1 is the utility model embodiment (ten shift transmissions) structural representation.
Fig. 2 is odd-side Pneumatic operating mechanism schematic diagram.
Fig. 3 is main tank operating mechanism fundamental diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is made specific descriptions:
As Figure 1-3, transmission assembly is divided into two casings, be respectively main tank 1, odd-side 3, in the main tank 1 five forward is arranged, two gears are arranged in the odd-side, realize the purpose of ten forward gears with this, top cover assembly 2 is the main tank operating mechanism, cylinder assembly 4 is the odd-side gear shifting actuating mechanism, and cylinder block 8 is the interlocking cylinder body.All gears of main tank switch to be finished by top cover assembly 2, the switching of odd-side high to low gear is finished by cylinder assembly 4, in odd-side cylinder intermediate portion a pore 11 is arranged, draw one road source of the gas and handle the lockable mechanism of main tank operating mechanism, before the odd-side cylinder is finished gearshift, can sealing not interlock gas circuit, locking main tank operating mechanism, after the odd-side cylinder is finished the gear switching, the odd-side cylinder provides one road source of the gas, and release interlocking gas circuit makes the main tank operating mechanism can finish gearshift.
When odd-side during at gear, as shown in Figure 2, odd-side is in low gear at this moment, and cylinder piston 12 is close to the right of cylinder, at this moment low gear suction port 9 has source of the gas to continue air feed, pore 11 can obtain source of the gas and supply with from cylinder, transmit air pressure to interlocking pore 7 shown in Figure 3, makes air pressure jack-up interlock spring 6, thereby make interlocking plunger 5 break away from interlocking position, in this time, top cover assembly 2 is not lockable, and can shift gears.When odd-side when hanging high gear, the high gear suction port 10 of odd-side cylinder has source of the gas to continue air feed, when promoting cylinder piston 12 in the odd-side cylinder to left movement, when odd-side also hangs gear fully, this time, cylinder piston 12 sealed pore 11, so that the interlocking gas circuit is closed, interlock spring 6 pushes up back interlocking plunger 5, locked shifting shaft is so that top cover assembly 2 can not shift gears, until odd-side is suspended to correct position fully, be that cylinder piston 12 is when being close to the cylinder left side, pore is ventilated for 11 these time again, and interlocking plunger 5 is pushed up back by air pressure, and top cover assembly 2 just can switch the main tank gear.In like manner, when odd-side is suspended to low gear from high gear, by opposite order, can guarantee equally the odd-side gear before not putting in place fully, main tank can not switch gear.
