Description
Technical field
The utility model discloses a kind of tractor frame beam, specifically a kind of front-wheel steering four wheel drive boat-type tractor vehicle frame.
Background technology
The use of boat-type tractor starts from China seventies in last century, and it utilizes slick and frivolous formula principle of work to carry out paddy-field-working, is one of Main Agricultural machinery of using of south China Rice Cropping region.Along with China's urbanization constantly advances, existing fraction horsepower boat-type tractor is difficult to the power demand in satisfied southern bulk paddy field.
Existing four wheel drive boat-type tractor mainly adopts the deck of boat to support the mode of whole driving system.In the operation of high-power boat-type tractor, easily there is the problems such as distortion, resonance in deck of boat structure, causes greater impact to driving system.Because boat-type tractor adopts slick and frivolous formula principle of work to carry out work, the overall box typed structure weight of the driving system that Conventional drum trac. adopts is excessive can not meet boat-type tractor demand.Along with technological advance, people consider to use front-wheel steering technology on the basis of four wheel drive, form front-wheel steering four wheel drive boat-type tractor, in this kind of tractor frame beam R&D process, it is found that, front-wheel steering four wheel drive boat-type tractor many employings differential steering, when turning to, energy consumption is large, easier greater impact is caused to vehicle frame, higher to the requirement of strength of vehicle frame; Further, owing to adopting front-wheel steering, the mounting plane of propons is high compared with the mounting plane of back axle, and existing tractor frame beam is difficult to meet installs needs.
Summary of the invention
The purpose of this utility model is to solve the problems of the technologies described above, and provides that a kind of structure is simple, structural strength is high, for the driving system of boat-type tractor and other structures provide the front-wheel steering four wheel drive boat-type tractor vehicle frame of strong protection and support.
Technical scheme comprises left girder and right girder, many crossbeams are connected with between described left girder and right girder, described many crossbeams hang crossbeam, auxiliary gear box after cross member, auxiliary gear box front cross rail, change speed gear box installation after cross member, change speed gear box installation front cross rail, driving engine after cross member, driving engine front cross rail and propons fixed beam by rear to being front followed successively by farm implements, the leading portion of described left girder and right girder is choose high step section, and described driving engine front cross rail and propons fixed beam are positioned at the leading portion of left girder and right girder.
On described left girder and right girder, symmetry is equipped with multiple shell support, and the lower end of described shell support is fixed on corresponding left girder or right girder.
Described change speed gear box is installed front cross rail and is provided with change speed gear box installing front support, and described change speed gear box is installed after cross member and is provided with change speed gear box installation after poppet.
Auxiliary gear box support is fixed with between described auxiliary gear box after cross member and auxiliary gear box front cross rail.
The front end of described left girder and right girder is connected with water tank fixed support.
Described propons fixed beam bottom surface is provided with propons and limits link stopper.
Beneficial effect:
1, the leading portion of left girder and right girder is designed to choose high step section, the installation requirement that during to adapt to front-wheel steering four wheel drive, front-wheel mounting plane is higher, ensures the reliable installation of each parts on vehicle frame.
2. the leading portion based on left girder and right girder is designed to choose high step section, and therefore the setting height(from bottom) of whole vehicle frame is sunk, and makes vehicle frame overhead nearer, improves intensity and the boat-type tractor operation stability of vehicle frame.
3. after declining for vehicle frame setting height(from bottom), shell directly can not be fixed on the problem on vehicle frame; devising multiple lower end and be fixed on shell support on corresponding left girder or right girder for installing shell, playing protection and supporting role to being arranged on each parts on vehicle frame simultaneously.
4. the utility model structure is simple, structural strength is high, for the driving system of boat-type tractor and other structures provide strong protection and support, be applicable to front-wheel steering four wheel drive boat-type tractor.
