Preferably, described left-right longeron (17) front end is provided with oily machine adapter plate, and driving engine is installed on it; Change-speed box (4) fixedly is located at left-right longeron (17) rear end.
Preferably, have on the described left-right longeron (17) and through hole is installed and is provided with fixed block.
Preferably, described operator's compartment underframe (10) is triangular structure, which is provided with the direction machine cutter and auxiliary gear box installation cutter position are installed.
Preferably, described back underframe (8) is rectangular configuration, and its inside is provided with support, which is provided with back axle and trailing wheel fixed mount.
Preferably, propons (14) frame passes front-wheel (15) axis at leaf spring (16).
Preferably, described operator's compartment underframe (10) is gone up fixedly direction machine (11) and auxiliary gear box (6), and wherein, direction machine (11) is positioned at the position near tow the head (12), and auxiliary gear box (6) is located at operator's compartment underframe (10) middle part.
Preferably, described back underframe (8) frame on back axle (9), back axle (9) the two ends trailing wheel (18) that is connected.
Preferably, propons equates with the ratio of front-wheel with the trailing wheel radius ratio with the ratio of back axle ratio.
Beneficial effect
1, equates with front and back wheel radius ratio ratio owing to front and back axle ratio ratio, whenever make, any gear drives synchronously before and after can both realizing and travels, overcome at present and can only realize synchronous situation at some gears, make that like this hill climbing ability of trac. is stronger, purposes is wider, and load carrying ability increases, and moves more steady, good reliability adapts to road driving under the harsies environment such as mountain area, mire, forestry especially.
2, flexibly connect replacement and be rigidly connected, be conducive to vibration damping and the smooth-ride of trac. like this; The manufacturing of towing the head and installation make itself and compartment underframe angle reach minimum, are conducive to like this reduce the corner that vehicle travels, and make the Vehicular turn sensitivity.
