Description

The special-purpose back axle of adobe machinery transport trolley

The utility model relates to a kind of vehicle of transportation.

At present, in producing, adobe also do not have special transport vehicle.Generally be to use three-wheeled farm transport vehicle.The back axle of this three-wheeled farm transport vehicle is made up of power-transfer clutch, change speed gear box, two semiaxis and two wheels.During use, drive the power-transfer clutch running by driving engine, again by the gear operation in the drive of the input shaft on the power-transfer clutch change speed gear box, thus two semiaxis runnings of the diff bonded assembly in drive and the change speed gear box.So just drive wheel.And carry out shift speed change by declutch shift shaft.Adopt three-wheeled farm transport vehicle transportation adobe to have following several problem: (1) is because the most of conditions of road, position, environment of the factory site of each machine brickkiln factory are poor, road is cheated protruding injustice, the gradient is big up and down, running velocity should not be too fast, and three-wheeled farm transport vehicle is suitable for moving on pitch, torsional forces is less, and speed per hour is higher.The damage rate height of car when therefore adopting three-wheeled farm transport vehicle transportation adobe is so must transform the change speed gear box of this car.(2) because the wheelspan of three-wheeled farm transport vehicle is 1200-1400mm, and during as the adobe transport trolley, wheelspan changes 900-980mm into, and the back axle of former change speed gear box is according to 1200-1400mm spacing design-calculated, and therefore dismounting, maintenance are all inconvenient.So in adobe is produced, need very much a kind of special transport vehicle.

The purpose of this utility model is to realize the special-purpose back axle of a kind of adobe mechanical transport, and this special use back axle is suitable for transporting under the ill-condition of brickkiln factory, and damage rate is low, and is convenient to dismounting and maintenance.

The utility model is realized by following manner.

The special-purpose back axle of this adobe machinery transport trolley, include power-transfer clutch, change speed gear box, two semiaxis, two wheels, and in order to control the declutch shift shaft of shift speed change, and shift fork, the input shaft of described power-transfer clutch is contained in the described change speed gear box by bearing, by bearing reverse gear shaft is housed respectively in this change speed gear box, the II axle, and described two semiaxis are affixed by the diff in bearing and this change speed gear box respectively, the other end of described two semiaxis connects described wheel respectively, being equipped with on the described input shaft can be along first power shift gear of this axis direction slip, second power shift gear, on described reverse gear shaft, be equipped with in order to the described first power shift gear ingear reverse gear shaft, first gear, in order to the described second power shift gear ingear reverse gear shaft, second gear, and reverse gear shaft transition gear, on described II axle, be equipped with and described reverse gear shaft transition gear ingear II axle transition gear, with the II shaft gear of the gear mesh of described diff, and by bearing be equipped with in order to the described first power shift gear ingear, and and the dual gear of described reverse gear shaft first gear mesh.

Be elaborated below in conjunction with accompanying drawing.

Fig. 4 is a scheme drawing of the present utility model

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model be on the basis of former three-wheeled farm transport vehicle, carry out improved.The input shaft 10 of the power-transfer clutch 2 of general three-wheeled farm transport vehicle back axle is contained in the change speed gear box 1, thereby drive the gear operation in the change speed gear box 1, and carry out shift speed change by declutch shift shaft 30,31, drive two-semiaxles 5 and two wheels 6 runnings by the diff in the change speed gear box 14 again.The utility model designs again to the gear installation site of change speed gear box 1 on this basis, to adapt to the needs of transportation adobe in brickkiln factory.Change speed gear box 1 middle gear installation site such as Fig. 2, Fig. 3, shown in Figure 4, when reversing gear operation, stirring driving lever 34 meshes first power shift gear 22 and the dual gear on the II axle 12 28 on the input shaft 10 by the I back fork 32 on the I back fork axle 30, reverse gear shaft first gear 25 engagements on dual gear 28 and the reverse gear shaft 11, make propulsive effort pass to reverse gear shaft 11, reverse gear shaft transition gear 23 and the II axle transition gear on the II axle 12 26 by reverse gear shaft 11 meshes again, propulsive effort is passed to II axle 12, by gear 29 engagements of the II shaft gear on the II axle 12 27 with diff 4, thereby two wheels 6 that drive on the two-semiaxle 5 turn round.When carrying out a retaining operation, by I back fork 32 first power shift gear 22 and first gear 25 of the reverse gear shaft on the reverse gear shaft 11 on the input shaft 10 are meshed, make propulsive effort pass to reverse gear shaft 11, similarly by reverse gear shaft transition gear 23, II axle transition gear 26; The gear 29 of II shaft gear 27, diff 4, thus two wheels 6 that drive on the two-semiaxle 5 turn round.When carrying out the second gear operation, by II retaining shift fork 33 second power shift gear 21 and second gear 24 of the reverse gear shaft on the reverse gear shaft 11 on the input shaft 10 are meshed, make propulsive effort pass to reverse gear shaft 11, similarly, and by reverse gear shaft transition gear 23, II axle transition gear 26; The gear 29 of II shaft gear 27, diff 4, thus two wheels 6 that drive on the two-semiaxle 5 turn round.The design of the gear installation site of the change speed gear box of this back axle is according to the demand of direction of travel in kiln factory and change speed and design-calculated.The power shift gear design and installation is on the high speed shaft at input shaft, makes reasonable in design.Because the back axle change speed gear box middle gear modulus of former three-wheeled farm transport vehicle is little, intensity is low, therefore in the utility model the module of gear in the change speed gear box is increased, and increases the intensity of profile of tooth, to adapt to adobe machinery working environment.

Because the spacing of former three-wheeled farm transport vehicle is 1200-1400mm, when changing the brick transportation into, spacing is 900-980mm.Therefore spacing dwindles greatly like this, when declutch shift shaft keep in repair, rear wheel and right axle shaft drg all after the dismounting, could must be taken out declutch shift shaft, and the replacing selector fork dismantles other each, changes each gear.Power-transfer clutch then will all be dismantled when maintenance in the seam of right axle shaft sleeve pipe, power-transfer clutch could be split out, and makes maintenance very inconvenient like this.So the utility model with the declutch shift shaft design and installation on gear shift cover.As Fig. 1, shown in Figure 3, described change speed gear box is provided with the hollow cover 35 of a projection, the inside of this projection hollow cover 35 communicates with described change speed gear box 1 inside, described declutch shift shaft 30,31 is inserted in the perforation of sidewall of this hollow cover 35, shift fork 32,33 on it is stretched in the described change speed gear box 1, in order to the declutch shift shaft retainer spring 36 of location usefulness, and steel ball 37 all be contained on the position on the perforation of a sidewall of this hollow cover 35.Declutch shift shaft of the present utility model is two, and promptly I back fork axle 30, II keep off declutch shift shaft 31, and corresponding with it shift fork is two, and promptly the I back fork 32, and II keeps off shift fork 33.Can carry out gear shift operation by driving lever 34.This back axle only needs dismounting hollow cover 35 when maintenance, can be with declutch shift shaft 30,31, and I back fork 32, II retaining shift fork 33 are all unloaded down, and can repair accessories such as other axle and gear simultaneously, and simultaneously, power-transfer clutch is also very convenient in unloading process.

In sum, special-purpose back axle of the present utility model is suitable under the ill-condition of brickkiln factory transportation, damage rate is low, and is suitable for the direction of advancing in kiln factory and the demand of change speed.And be convenient to dismantle and maintenance.
