Abstract
The utility model relates to a post drag link type two gears auxiliary speed variator. A middle gear sheathed on a middle shaft is composed of a high-gear and a low-gear which are combined, and the high-gear is engaged with the end tooth of an input shaft. A control mechanism is composed of a hand operating link and a shifting fork shaft, wherein, one end of the shifting fork shaft is connected with the hand operating link, the other end is connected with a sliding gear through a shifting fork, and the sliding gear is driven to move in a shaft direction through the hand operating link to be engaged with the low-gear of the middle gear or be engaged with the end tooth of the input shaft. The utility model has the advantages of simple and compact structure, convenient production and maintenance, easy operation and simple gear shift.
Description
The utility model relates to the speed-changing mechanism of automobile, and particularly a kind of rearmounted rod-pulling type two with the Automotive transmission adapted keeps off demultiplicators.
Existing NJ130 agricultural vehicle exists hill climbing ability poor for a long time, and it is poor to overcome difficulties the ground-surface driveability, also is difficult to overcome above-mentioned defective at bottom gear.Though had the fwd deceleration demultiplicator of main-gear box in the prior art, increased the load of main gearbox, the life-span of having reduced main gearbox; In addition, also have the planet demultiplicator that is contained in the main gearbox back, its shortcoming is that complex structure, manufacturing are difficult, manufacturing cost is high, and is poor because of other interchangeability of parts, makes maintenance difficult.
The purpose of this utility model is to provide a kind of can effectively improve the automobile hill climbing ability and at the rearmounted rod-pulling type two retaining demultiplicators of difficult road traveling ability.
Above-mentioned purpose of the present utility model is to realize by such technical scheme, be a kind of rearmounted rod-pulling type two retaining demultiplicators, comprise housing, input shaft, tween drive shaft, output shaft, countershaft-gear, cliding gear and pull bar steering unit, it is characterized in that: the intermediate gear that is enclosed within on the tween drive shaft is formed by top gear gear and bottom gear gear combination, the end tooth engagement of high speed gear and input shaft; Steering unit is made of hand operating lever and declutch shift shaft, wherein, declutch shift shaft one end is connected with hand operating lever, and the other end links to each other with cliding gear by shift fork, moves axially and meshes with the engagement of intermediate gear bottom gear tooth or with the input shaft end tooth by hand operating lever drive cliding gear.
Said structure of the present utility model can further specify by the embodiment that accompanying drawing provides.
The utility model has following accompanying drawing:
Accompanying drawing 1 is the structure cutaway view of the utility model embodiment;
Accompanying drawing 2 is the utility model and main gearbox bonded assembly outside drawing;
Accompanying drawing 3 is that the A of accompanying drawing 2 is to view.
Referring to accompanying drawing: rearmounted rod-pulling type two retaining demultiplicators among the figure, comprise housing, input shaft 5, tween drive shaft 7, output shaft 4, countershaft-gear 6, cliding gear 3 and pull bar steering unit, it is characterized in that: the intermediate gear 3 that is enclosed within on the tween drive shaft 7 is formed by top gear gear and bottom gear gear combination, the end tooth engagement of high speed gear and input shaft 5; Steering unit is made of hand operating lever 1 and declutch shift shaft 2, wherein, declutch shift shaft one end is connected with hand operating lever, and the other end links to each other with cliding gear 3 by shift fork, moves axially and meshes with the engagement of intermediate gear bottom gear tooth or with the input shaft end tooth by hand operating lever drive cliding gear.
The utility model demultiplicator directly is contained in the main gearbox back, connects in taking with main gearbox to constitute a compound transmission, and the back is connected with transmission shaft by the output shaft flange.
Transmission process of the present utility model is such: power is by driving engine → power-transfer clutch → main gearbox → demultiplicator → transmission shaft → back axle → tire.
In use of the present utility model, demultiplicator is hung top gear usually and is promptly directly kept off, and slide teeth and input shaft end tooth engagement at this moment respectively keeps off power by the demultiplicator input shaft with main gearbox, is directly passed to the demultiplicator output shaft.If meet difficulty the road surface, or climb when needing further to increase power, main gearbox is hung a retaining, the demultiplicator down shifting, it is the bottom gear tooth engagement that joystick drives cliding gear and intermediate gear, outputting power is doubled, and this moment, the speed of a motor vehicle reduced by one times, made it vehicle at an easy rate by difficult road surface and Po Lu.
In section-drawing, cliding gear 3 is under the effect of pull bar 1 and shift fork 2, and forward, slip will combine with input shaft gear, constitutes top gear, backward, will combine with tween drive shaft bottom gear gear, constitutes bottom gear.For the ease of installing, joystick 1 is arranged on the right side of main gearbox 9 joysticks 8.For fear of the impact of putting into gear, the increment of cliding gear 3 adopts big chamfering.
The good effect that the utility model produces owing to described structure is very significant: promptly to put demultiplicator simple in structure for the utility model, make easy to maintenance, zero, parts are general, interchangeability is strong, compact conformation, the good looking appearance gearshift is light, flexible.In addition, the cliding gear increment adopts big chamfering, makes gearshift easily, has reduced the gear impact, to improving gear life obvious effects is arranged.
The utility model is to the hill climbing ability that improves car load and overcome difficulties the ground-surface ability and produced positive effect.Be particularly suitable for being installed in the NJ130 agricultural vehicle, make an amendment slightly, also can use on the automobile of other model.
