Abstract
The utility model relates to a small rear-driving transporting tractor which is characterized in that a diesel engine 3 is positioned on a front axle 17; the motive power of the diesel engine can reach a rear axle 13 through the transmission of a clutch 1, an auxiliary gear box 4, a main gear box 7 and a transmission axle 14, and accordingly, the drive of rear wheels can be realized. The utility model not only has high speed, strong climbing capacity, and safe and reliable braking, but also can fully perform the existing actual loading function of the tractor. The small rear-driving transporting tractor has the advantages of simple structure, increased seats for passengers, convenient loading and unloading, flexible and convenient operation, safe and reliable use, etc.
Description
The utility model relates to a kind of small-sized transportation type trac..
At present, existing hand-variable transport plane and the bearing circle trac. that sways one's hips mostly adopts f-w-d, mechanical type is adopted in the front and back wheel braking, the shortcoming of this type is: speed is slow, load carrying ability is little, adhesive ability is little, hill climbing ability is low, turn to underaction, the braking is unreliable, can not bring into play the characteristics of transportation type trac. " Duola hurries up " effectively.Though what the disclosed radial type rear drive of ZL95209378 transportation type trac. adopted is rear drive, because its vehicle frame is divided into front and back two parts, and be to adopt the traction articulated mounting, so vehicle frame is stable bad.
The purpose of this utility model provides that a kind of speed is fast, load carrying ability is big, adhesive ability is big, hill climbing ability is strong, turns to flexibly, brake safe is reliable, can give full play to the rear drive transportation type trac. of trac. " Duola hurries up " characteristics.
The purpose of this utility model is such realization:
A kind of small-sized rear drive transportation type trac. is made up of parts assemblies such as diesel engine 3, power-transfer clutch 1, auxiliary gearbox 4, main-gear box 7, transmission shaft 14, front axle 17, back axle 13, steering swivel system 5, brake system 8, hydraulic pressure unloading system 11, suspension 10, vehicle frame 12, electric equipment 2, operator's compartment 6 and loading spaces 9.It is characterized in that diesel engine 3 is positioned on the front axle 17, its power arrives back axle 13 by power-transfer clutch 1, auxiliary gearbox 4, main-gear box 7 and transmission shaft 14 transmissions, thereby realizes back-wheel drive.The main-gear box of band auxiliary gearbox by the major-minor shifter bar of control major-minor change speed gear box, can be realized nearly 8 D Drives and 2 backward gears.The right flank of main-gear box 7 is equipped with power takeoff 16, in order to transmission hydraulic pressure unloading system 11.Steering swivel system 5 is made up of steering hardware on wheel steering device, pitman arm and the front axle.Brake system 8 is made up of dual circuit foot brake system and hand braking system 15.Dual circuit foot brake system is made up of master brake cylinder, front and back four-wheel wheel cylinder, pipeline and steering unit.Double-pipe line hydraulic brake is adopted in braking, and brake safe is reliable.Hydraulic pressure unloading system 11 is made up of gear type pump, distributing box, oil cylinder, fuel tank and pipeline, and the commutation of control dispenser just can reach the compartment and tumble and reset.Vehicle frame 12 adopts whole posture, and operator's compartment 6 is made up of ceiling 21, hood frame 18, front windshield 19, left-hand mirror 20 and seat 22, and the operator's compartment passenger seat is two.Loading space 9 terrain clearances are 660 millimeters, are easy to loading.
Owing to adopted technique scheme, compared with prior art, not only speed is fast, hill climbing ability is strong for the utility model, brake safe is reliable, but also brought into play the original actual load ability of trac. fully, and have advantages such as simple in structure, that the passenger seat increases, handling goods makes things convenient for, flexible and convenient operation, and is safe and reliable.
Fig. 1, structure master of the present utility model look scheme drawing;
Fig. 2, structure schematic top plan view of the present utility model;
The structural representation of Fig. 3, operator's compartment of the present utility model.
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described further.
A kind of small-sized rear drive transportation type trac., driving engine is selected the vertical water-cooled diesel engine 3 of the single cylinder of 8.8～13.2KW power for use, front axle 17 is selected TY-1608 farm vehicle front axle for use, back axle 13, direction machine assembly, dual-line braking system etc. adopt the structure of BJ-130, hand braking system 15 is general with NJ-130's, forms for the NJ-130 change speed gear box increases odd-side 4 with the change speed gear box of secondary speed change.Major-minor speed change driving lever be positioned at change speed gear box on cover, handle secondary speed change driving lever, be used for the high and low shift speed change; Handle main transformer speed driving lever and be used for D Drive and backward gear.By control major-minor shifter bar, can obtain different eight kinds of D Drives and two kinds of reverse speed of a motor vehicle.There is power takeoff 16 main-gear box 7 sides, by handling power takeoff 16 driving levers, the transferring power of may command hydraulic pressure unloading system.Power-transfer clutch 1 of the present utility model, hang 10, compartment 9, hydraulic pressure unloading system 11, electric equipment 2, seat 22, ceiling 21 and hood frame 18 etc. all with workers and peasants-12K
1Type bearing circle waist-twisting machine identical, particularly seat 22 has two.In addition, front windshield 19 and left-hand mirror 20, front-wheel steering are established in operator's compartment 6 front portions, vehicle frame 12 adopts whole posture, brake system 15 adopts the BJ-130 double-pipe line hydraulic brake, and the employing of these technology has improved stability, traveling comfort and safety that the utility model is driven greatly.
