The engine, the clutch, the main gearbox and the auxiliary gearbox are sequentially in rigid connection to form a whole to be arranged on the front portion of the tractor frame, the front axle is arranged on the front lower portion of the tractor frame, the back axle is arranged on the back lower portion of the tractor frame, the back axle is connected with the auxiliary gearbox through the transmission shaft, the front axle and the back axle are connected with the tractor frame through the plate spring, the weight box is installed on the back upper portion of the tractor frame, and the power output box and the hydraulic suspension are installed on the back end face of the tractor frame. The tractor frame is composed of a front tractor frame body and a back tractor frame body, longitudinal beams on the two sides of the front tractor frame body and the two sides of the back tractor frame body are mutually connected in a sleeved mode, and the front tractor frame body and the back tractor frame body can be flexibly adjusted in the length direction of the front tractor frame body and the back tractor frame body and are fixedly connected by the same set of fixing bolts in a fastened mode. The full-frame type tractor is compact in structure, reliable in usage and good in safety, an integral transporting unit can be formed, and the requirements for farmland operation and transporting operation can be met at the same time.
Description
Technical field
The utility model belongs to trac. field, relates to a kind of adjustable shaft apart from full posture trac..
Background technology
As everyone knows, trac. wheelbase is one of important parameter of complete machine of tractor design.Its size affects the main performance of tractor set operation.Whether trac. of the prior art is by being divided into and having posture and without two types of postures, be about to each drive disk assembly of trac. and be fixed together rigidly, without connecting with vehicle frame without posture with vehicle frame; Have posture by integral rigidity vehicle frame, each parts of trac. to be combined, its driving system is conventionally with transmission shaft.No matter have posture or without posture trac., the size of its wheelbase is mainly that the requirement that meets its farmland operation is determined, and limited by its rigid construction, the size of wheelbase all can not be adjusted.When trac. carries out hauling operation, trac. is connected with trailer by the drawbar frame at rear portion, forms radial type transport unit, its safety and less stable.Therefore the structure of this rigid wheelbase is difficult to meet the requirement of trac. farmland operation and hauling operation simultaneously.
Utility model content
The purpose of this utility model is exactly in order to overcome the deficiency in above technology, a kind of compact conformation is provided, use reliable, safety is good, can form integral type transport unit, meet farmland operation and hauling operation requirement simultaneously, is convenient to the adjustable shaft of going into operation fast apart from posture trac. entirely.
The purpose of this utility model is to adopt following technical scheme to realize: adjustable shaft, apart from full posture trac., comprising: vehicle frame, driving engine, power-transfer clutch, main-gear box, auxiliary gearbox, propons, back axle, transmission shaft, power output box, hydraulic suspension, leaf spring, weight box, loading space; Driving engine, power-transfer clutch, main-gear box, auxiliary gearbox are rigidly connected to be successively integral and are arranged in vehicle frame front portion, lower disposed propons before vehicle frame, vehicle frame rear lower is arranged back axle, back axle is connected by transmission shaft with auxiliary gearbox, propons adopts leaf spring to be connected with vehicle frame 1 with back axle, vehicle frame upper back is provided with weight box, and power output box and hydraulic suspension are installed on vehicle frame aft end face.
Two side girders of the forward and backward vehicle frame of vehicle frame are socketed mutually, the adjustment of stretching along its length of forward and backward vehicle frame, and forward and backward vehicle frame is fastenedly connected with one group of bolt of rear end plate.
The utility model can reach following beneficial effect after adopting technique scheme:
1, driving engine, power-transfer clutch, main-gear box, auxiliary gearbox adopt bolt to be rigidly connected, then connect by transmission shaft the main transmission that back axle is combined into trac., simple in structure, easy to maintenance, use reliably, are convenient to complete machine and arrange.
2, adjust the length of vehicle frame, shorten trac. wheelbase, in weight box, putting into suitable clump weight increases adhesive weight, then by equipment and machine coordinations such as power take-off shaft, hydraulic suspensions, form traditional farm tractor, can meet the requirement of farmland operation unit.
3, adjust the length of vehicle frame, increase trac. wheelbase, container is directly installed on vehicle frame, form integral type transporting tractor, can meet the requirement of hauling operation unit.Compare with trac. radial type transport unit, safety and stability significantly improve.
accompanying drawing explanation
Fig. 1 is that the utility model adjustable shaft is apart from the structural representation of full posture trac. farmland operation unit;
Fig. 2 is that the utility model adjustable shaft is apart from the structural representation of full posture trac. hauling operation unit.
the specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.As shown in Figure 1 and Figure 2, adjustable shaft, apart from full posture trac., is mainly comprised of vehicle frame 1, driving engine 2, power-transfer clutch 3, main-gear box 4, auxiliary gearbox 5, propons 6, transmission shaft 7, back axle 8, power output box 9, hydraulic suspension 10, leaf spring 11, weight box 12, loading space 13.Driving engine 2, power-transfer clutch 3, main-gear box 4, auxiliary gearbox 5 are rigidly connected and are integral successively, be arranged on the front portion of vehicle frame 1, vehicle frame 1 rear lower is provided with back axle 8, and auxiliary gearbox 5 connects back axle 8 by transmission shaft 7, back axle 8 two ends are installed and are driven wheel, form the driving system of trac.; The front bottom of vehicle frame 1 is provided with propons 6, propons 6 is connected with vehicle frame 1 by leaf spring 11 with back axle 8, vehicle frame 1 upper back is provided with weight box 12, and power output box 9 and hydraulic suspension 10 are installed on vehicle frame 1 aft end face, and vehicle frame 1 front upper part is provided with car bonnet and handles parts.
Vehicle frame 1 adjustment of can stretching along its length, unclamps bolt of rear end plate, shortens the length of vehicle frame 1 to accompanying drawing 1 state, is connected composition farmland operation unit by equipments such as power output box 9, hydraulic suspensions 10 with facility.
Increase the length of vehicle frame 1 to accompanying drawing 2 states, the weight box 12 that vehicle frame 1 upper back is installed changes the outfit as loading space 13, forms hauling operation unit.
During trac. work, according to need of work, be adjusted to farmland operation unit or hauling operation unit, the power of driving engine reaches back axle 8 by driving engine 2, power-transfer clutch 3, main-gear box 4, auxiliary gearbox 5, transmission shaft 7, drives vehicle wheel rotation, can carry out respectively farmland operation or hauling operation.
