Abstract
The utility model discloses a single-dual combined driving transfer case for an agricultural vehicle. The single-dual combined driving transfer case for the agricultural vehicle comprises a box body; two poking fork shafts, an input shaft, a middle shaft and two output shafts are arranged in the box body from top to bottom in parallel; two same input gears capable of sliding back and forth sleeve the input shaft; two same middle transition gears capable of freely rotating fixedly sleeve the middle shaft; the two output shafts are arranged left and right; rolling bearings respectively sleeve two ends of the output shafts and are contained in the middle of the box body in parallel; two same output gears normally meshed with the middle transition gears are respectively arranged on the left and right output shafts; the poking fork shafts are arranged at left and right sides of the same horizontal position; a poking fork for controlling a driving gear of the input shaft to slide back and forth is arranged on each of the left and right poking fork shafts. The single-dual combined driving transfer case is reasonable in configuration, novel in design and layout, strong in power, small in size, has the advantages of multiple functions, good performance and reliable quality, and is suitable for the multifunctional agricultural vehicles.
Description
Technical field
The utility model relates to gearbox technical field, relates in particular to the single duplex of a kind of agricultural vehicle and closes driving transfer case.
Background technique
Front and back wheel Dual Drive agricultural vehicle extremely suitable in field, hillside, field, beach, mud ground, desert, mountain region and the severe Ground Operation of environment; And the occasion, wheel list such as on the good road surface of amalgamation, start, travel, turn to drive to have given play to flexibly, economic, effect reliably.Therefore, for the agri-vehicle of the multi-functional assemblies such as agro-farming operation, transport, handling hoisting heavy or tipping bucket, need to its configure a kind of compact structure and can singly drive, Dual Drive have the transfer case of power taking function.
Model utility content
The purpose of this utility model is the deficiency in order to make up prior art, provides the single duplex of a kind of agricultural vehicle to close driving transfer case.
The utility model is achieved through the following technical solutions:
A kind of agricultural vehicle closes driving transfer case by single duplex, include casing, it is characterized in that: declutch shift shaft, input shaft, jack shaft, output shaft are installed in described casing from top to bottom side by side, on described input shaft, be set with two input gears identical and that can slidably reciprocate, on described jack shaft, fixed cover is equipped with rotation two identical middle transition gears freely; Described output shaft is each one around, its two ends put respectively rolling bearing bear side by side with casing in the middle of, the output gears identical with two of the normal engagement of middle transition gear are respectively housed on left and right output shaft; Described declutch shift shaft is two, and it is respectively the left and right declutch shift shaft in same level position, on described left and right declutch shift shaft, the shift fork that control inputs axle driving gear slidably reciprocates is respectively installed; Described input shaft one end is fixed on casing by bearing, and the other end is contained in the gear hole of the oil pump actuation gear axle head corresponding with it.
Described box cover has upper cover, and one end of described input shaft is provided with input flange, and two outer end fixed covers of described output shaft are equipped with output flange, and the outer end fixed cover of the output shaft of right-hand member is equipped with hand braking system disk.
Its working principle is:
Toward the power → input flange of transfer case input speed change, input shaft, input gear → jack shaft intermediate gear,
→ output shaft output gear →
Situation one: move to right → left end of input gear output gear → left end output speed ratio of stirring input shaft left end when left end shift fork is 1.792 power.(left end driving wheel)
Situation two: move to left → right-hand member of input gear output gear → right-hand member output speed ratio of stirring input shaft right-hand member when right shift fork is 1.792 power.(right-hand member drives wheel.Left end input gear is still in the time of engagement, and vehicle drives for two.）
Situation three: move to right → oil pump of the input gear gear shaft → output of stirring input shaft right-hand member when right shift fork drives oil pump.
The utility model has the advantages that:
1, reasonable in design, compact structure, simple, volume is little.
2, output power is large, and transmitted power is large, and kinetic equation loss is little, and mechanical efficiency is high.
3, structure is terse, simple to operate, easy to maintenance.
4, component manufacturing process is simple and easy, and assembling is lightly convenient.
5, supporting cost is low, has greatly strengthened the market competitiveness.
The utility model has the advantages that:
The configuration of the utility model structure rationally, layout is novel, power strength is strong, volume is little, has advantages of that function is multiple, performance good, reliable in quality, is applicable to multifunctional agricultural vehicle.
