Abstract
The utility model relates to a front wheel independent suspension rack steering system for a four-wheel farm vehicle. The utility model is mainly composed of a double-cross arm spiral spring independent suspension rack, a combined drive box, a ball fork type universal joint, a steering joint, a drive semi-shaft, a steering transmission mechanism, etc. The combined drive box and a motor are both fixed on a vehicle frame. Influence resulting from wheel hop is avoided. The problem of belt transmission quality of a tradition three-wheel farm vehicle is solved. The technical proposal inherits the advantages of simple structure and low cost of the three-wheel farm vehicle. Meanwhile, control stability and drive power are improved. The utility model is particularly suitable for belt driven four-wheel farm vehicles with a single cylinder diesel as the power.
Description
The utility model relates to a kind of four-wheel farm vehicle front wheel independent suspension driving and steering system, particularly is applicable to the single cylinder diesel to be power, bel-drivenn four-wheel farm vehicle f-w-d system.
Traditional three wheeled transport vehicle used for farm all adopts the layout of front-wheel steering, back-wheel drive, and its representative type transmission connected rear axle combines as a whole power-transfer clutch, change-speed box, diff, semiaxis, axle housing, and the power of driving engine that is fixed on vehicle frame is through the belt-driving input clutch.The advantage of this form be simple in structure, easy to manufacture, cost is lower, but its road-holding property is poor, and because the bel-drivenn width between centers is subjected to the influence of wheel bounce, neglects tight neglecting and relax, significantly increase the wearing and tearing and the loss in efficiency of belt, also reduced the riding comfort of vehicle simultaneously.
A simple deformation of tradition three wheeled transport vehicle used for farm is to use the four-wheel farm vehicle of propons instead, still adopts the transmission connected rear axle.The class that this structure has improved former car has improved road-holding property, but does not solve the problem that the belt-driving width between centers is influenced by wheel bounce.
Representative type four-wheel farm vehicle then generally adopts the structure of light truck, better performances, and class is higher, makes complexity, and cost is higher.
Chinese patent (application number) 982003315 provides a kind of brand new four-wheel farm vehicle technical scheme, change the connected rear axle type of drive of traditional three wheeled transport vehicle used for farm into preceding transversal spring independent suspension driving steering structure, combination transmission gearbox with clutch, speed change, differential function also is fixed on the vehicle frame, still adopt belt-driving, the bel-drivenn width between centers can remain on perfect condition, the influence of having avoided wheel bounce to bring effectively.
The purpose of this utility model provides a kind of brand new four-wheel farm vehicle technical scheme, and inheriting tradition three wheeled transport vehicle used for farm advantage simple in structure, easy to manufacture, lower-cost is improved road-holding property and power-handling capability simultaneously, thoroughly solves the belt-driving quality problems.
The purpose of this utility model is achieved in that the connected rear axle type of drive with traditional three wheeled transport vehicle used for farm changes the two transverse arm coil spring independent suspensions driving of front-wheel steering structure into, combination transmission gearbox with clutch, speed change, differential function also is fixed on the vehicle frame, still adopts belt-driving.
Combination transmission gearbox of the present utility model and driving engine all are fixed on the rigid-frame, the bel-drivenn width between centers can remain on perfect condition, the negative effect of having avoided wheel bounce to bring effectively, and transmission of power is stable, efficient height, the service life of significant prolongation belt simultaneously; Its f-w-d structure has also been strengthened the power-handling capability of vehicle, is more suitable in agricultural operation.
Compare with the preceding transversal spring independent suspension of aforementioned patent, coil spring of the present utility model has little, the non-lubricating advantage of quality with respect to steel spring, is more suitable in rural dirt road.
Major part of the present utility model and assembly can be selected the standardized product of existing jeep, minicar, farm vehicle for use, have not only guaranteed quality, have also realized lower productive costs.
The utility model is described in further detail below in conjunction with Figure of description and embodiment.
Fig. 1 is a partial rear view.
Fig. 2 is a partial side view.
Fig. 3 is local backsight structural representation.
Fig. 4 is a fragmentary top TV structure scheme drawing.
The utility model mainly is made of parts such as main car frame (1), subframe (2), the two transverse arm coil spring independent suspensions (3) of front-wheel, combination transmission gearbox (4), Weiss universal joint (5), steering swivel (6), jack shaft (7), steering gears (8).
Subframe (2) is positioned at the front portion of main car frame (1), is fixed under four of main car frame to stretch on the frame beam (9).Combination transmission gearbox (4) is vertically fixed in the top of subframe by screw, and its front portion is a box of tricks, about an axle drive shaft (10) is respectively arranged, boss connects with the Hooke's joint (11) of jack shaft (7); Its middle part is a representative type 3+1 gear gearbox; The rear portion is the belt pulley (13) of built-in power-transfer clutch (12), and it constitutes transmission of power by drive belt (14) and the driving engine (15) that is installed in main car frame (1) middle part.
In independent front suspension (3), Lower control arm (16) forms hinge by arm axle with the end of subframe (2) and is connected, and the arm axle of upper suspension arm (17) is fixed on front suspension support (18) waist of main car frame (1); The two ends up and down of steering swivel pillar (19) are hinged with upper suspension arm and Lower control arm respectively by ball end (20); Coil spring (21) vertical direction is arranged in upper suspension arm and front suspension and props up space between the top of the trellis, and its two ends are fixed on upper suspension arm and the support by gland (22) respectively.So just constitute two transverse arm torsion bar spring independent suspensions of a novelty, move on helical spring to the necessary jack shaft of before driving (7) and dodge out desirable space.
Weiss universal joint (5), steering swivel (6) are selected the assembly of Beijing BJ212 motor turning drive axle for use, the spherical bearing of steering swivel (23) is fixed on the steering swivel pillar (19), and the outer semiaxis (24) of Weiss universal joint connects with jack shaft (7) by Hooke's joint (25).
The middle part of jack shaft (7) is provided with the free-sliding spline of being made up of cliding yoke and castellated shaft and is connected (26), with the variation of the propeller shaft length that causes of compensation wheel bounce.
Steering gear (8) is the breakaway-element tierod tie rod linkage that adapts to independent suspension structure,
Be associated with vertically " yielding formula " pull bar (27) between Lower control arm (16) and main car frame (1) front end cross beam, two ends are that rubber block is hinged.Its effect is the longitudinal impact that the buffering wheel transmits.
In sum, the moment of torsion of driving engine (15) drives wheel through jack shaft (7), Weiss universal joint (5) again by belt-driving input combination transmission gearbox (4), realizes f-w-d.Because combination transmission gearbox and driving engine all are fixed on the vehicle frame, belt-driving can remain on perfect condition, the influence of having avoided wheel bounce to bring.
In addition, total Chengdu such as wheel, steering swivel, suspension, transmission gearbox is fastened on the subframe, forms a big independent assembly, and it is convenient especially to install, dismantle, keep in repair.
