Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further:
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of vehicle frame of cross-country traveling ability wheelspan energy step-less adjustment, comprises the upper frame 1 being provided with driving engine, drive axle, and described upper frame 1 is hinged by left side connecting rod 2 and sinistral carriage 4; The right side of described upper frame 1 is hinged with swing axle 8, and swing axle 8 is hinged by right side connecting rod 7 and dextral carriage 5; Left-side support screw rod 3 is hinged with between described left side connecting rod 2 and sinistral carriage 4; Right side support screw rod 6 is hinged with between described right side connecting rod 7 and dextral carriage 5;
Described sinistral carriage 4 is provided with left side front-wheel and left side rear wheel, the left side connecting rod 2 be articulated and connected between described sinistral carriage 4 and upper frame 1 is three, two, inner side is in a plane, a connecting rod in outside is in another plane, three parallel left side connecting rods 2 form the parallel four-bar mechanism in a space with the upper frame 1 of its upper articulation with the sinistral carriage 4 of lower hinge, i.e. left side four-bar mechanism;
Described dextral carriage 5 is provided with right side front wheel and right side rear wheel, right side connecting rod 7 hinged between described dextral carriage 5 and the swing axle 8 being arranged on on the right side of upper frame 1 is three, two, inner side is in a plane, a connecting rod in outside is in another plane, three parallel right side connecting rods 7 form the parallel four-bar mechanism in a space with the swing axle 8 of its upper articulation with the dextral carriage 5 of lower hinge, i.e. right side four-bar mechanism.
Vehicle frame of the present invention is sectional construction, and whole vehicle frame to become a movable mechanism by upper frame, sinistral carriage, swing axle, dextral carriage with right side rod hinge connection by left side connecting rod.If car gage can not meet agriculture requirement when carrying out farm work, can by regulating the length of the studdle of arranged on left and right sides respectively, make sinistral carriage, dextral carriage relative to upper frame sway, to change the distance between sinistral carriage and dextral carriage, make left and right wheels apart from carrying out step-less adjustment according to agriculture requirement, because left and right vehicle frame and upper frame form parallelogram lindage, ensure regulating wheel distance time about vehicle frame all the time horizontal direction move, rotation of wheel plane vertical ground all the time, leaning angle, the casterangle of front-wheel steering column are constant.In the process of walking, dextral carriage, right side connecting rod and swing axle can carry out swing by opposing left vehicle frame, and vehicle still can be landed by four wheels when surface irregularity is larger, ensure the stability of vehicle to run.When this vehicle frame carries out farm work, upper frame exceeds crops top, wheelspan can carry out step-less adjustment according to agriculture requirement, mechanical wounding to crops when effectively avoiding vehicle farm work, solves high general character when vehicle carries out farm work and wheelspan can carry out step-less adjustment problem according to agriculture requirement.
The present invention is by being provided with movable left side four-bar mechanism in the left side of upper frame and right side is provided with movable right side four-bar mechanism, right side four-bar mechanism by swing axle and upper frame hinged, define a movable integrated model on the whole, can ensure that vehicle still can land by four wheels when surface irregularity is larger, ensure the stability of vehicle to run; When this vehicle frame carries out farm work, upper frame exceeds crops top, wheelspan can carry out step-less adjustment according to agriculture requirement, mechanical wounding to crops when effectively avoiding vehicle farm work, solve high general character when vehicle carries out farm work and wheelspan can carry out step-less adjustment problem according to agriculture requirement, avoid agricultural machinery injury to crops when farm work, raising crop yield is ensured that crops good harvest serves positive booster action.
Above case study on implementation is only for illustration of the preferred embodiment of the present invention; but the present invention is not limited to above-mentioned embodiment; in the ken that described exercising ordinary skill possesses; the any amendment done within the spirit and principles in the present invention, equivalent to substitute and improvement etc., the protection domain of the application all should be considered as.
