Abstract
The utility model relates to a small four-wheel tractor which is directly transmitted by gears, composed of the front axle assembly of a belt-transmission small four-wheel tractor, a back driving wheel assembly, a steering machine assembly, the cladding element of a gearbox assembly, a vertical engine assembly, a front axle carrier, a gap bridge casing, a clutch assembly, connection box body and direction-changing bevel gears. An existing belt-transmission four-wheel tractor is modified into a direct gear-transmission small four-wheel tractor by using the connection box body and a group of direction-changing bevel gears, so the disadvantages of the belt-transmission four-wheel tractor is eliminated.
Description
The utility model is bevel gear to be set to change belt-driving into the direct geared small four-wheel tractor by a connect box, former change speed gear box I axle.
Known belt-driving small four-wheel tractor, owing to use horizontal cylinder diesel engine and belt-driving, diesel oil, consumption of lubricating oil are big, and driving efficiency is low, and element part is easy to wear.Adopt the vaporation-type water cooling, water tank often is in fluidized state, influences power and normally brings into play, domestic limited production, external eliminating.
The purpose of this utility model be to the belt-driving small four-wheel tractor improve, Assembling gear transmission small four-wheel tractor.By connect box vertical engine is connected with belt-driving small four-wheel tractor back axle change speed gear box, produces a kind of new gear transmission small four-wheel tractor, eliminated the shortcoming of belt-driving small four-wheel tractor.
Gear transmission small four-wheel tractor of the present utility model is achieved in that front axle assy, rear drive sprocket assembly, steering box assembly, transmission assembly and the cover panel with the belt-driving small four-wheel tractor is support, equipped vertical engine assembly, front axle carrier, gap bridge housing, clutch assembly and newly-installed connect box, power commutation bevel gear etc., realize the gear small four-wheel tractor that direct transfers, see Fig. 1.
Connect box (8) is the framed structure casing, front end and vertical engine gap bridge housing (6) bolted; Rear end and belt-driving small four-wheel tractor change speed gear box (9) bolted.I axle (13) is supported with bearing in the casing both sides, and the extension of I axle (13) front end is connected with universal-joint (12) spline.I axle (13) key connection duplex fixed gear wheel (22) is seen Fig. 2, Fig. 3 in the casing.
II axle (15) is positioned at I axle (13) top, is that an end has the strong axle of spending of bevel gear, fixes with casing by bearing (14,18) supporting, extends to change speed gear box (9) through change speed gear box through hole (19).II axle (15) is equipped with double-sliding gear (17) in the casing, and device one gear shift fork is stirred double-sliding gear (17) according to gear change hand lever (16) on this gear, realizes that former six gears that advance change the conversion of many gears, see Fig. 2.
Connect box finishes transmission of power and speed change can take to establish in the casing I axle (26), II axle (27), fixes one group of straight gear (28) with key on it, sees Fig. 4; Also can take to improve engine center---promptly move down front axle carrier (2) and wave axis hole distance or driving engine connecting bore.Specifically be in the connect box (8) axle (29) that one one end has bevel gear to be set, this end extends to change speed gear box through change speed gear box through hole (30), and other end extension is connected with universal-joint (12) spline, sees Fig. 5.
I axle (25) in the change speed gear box (9), be fixed on the casing with single-row garden taper roller bearing (24) supporting, near the fastening bevel gear of bolt with flange (20) its central authorities, bevel gear (23) engagement on bevel gear (20) and the connect box output shaft, to finish transmission of power and direction transformation, see Fig. 2, Fig. 4, Fig. 5.
Other detail assembly of gear transmission small four-wheel tractor of the present utility model is identical with existing small four-wheel tractor, sees Fig. 1.
