Abstract
The utility model relates to a front driving four wheel tractor shock-proof turning device. The front transmission shaft of the utility model is two half shafts which are hinged to the output shaft of the gearbox through double offset universal joint A separately. Two front wheels are hinged to the end of the other half shaft through double offset universal joint B. A pull rod for steering gear is connected to knuckle on front wheel hub, synchronizing steering tiller is connected to both left and right wheel hub. Diesel engine is positioned on a chassis, and the chassis is connected to the front axle by a spring. Change of angle between front wheel and the half axle while steering the wheel can turn the car. When road is uneven, the front wheel move up and down, the half shaft will swing which can reduce vehicle vibration. At the same time, because of the spring between the chassis and the front axle, the influence of vibration on vehicle while the diesel engine running is greatly reduced, and impact of uneven road on the body is also reduced. This device is flexible in turning, easy to operate; stabile, safe and reliable; with enhanced climbing ability; comfort and easy to drive; the utility model applies to the poor road in rural and mountain area; which can also reduce engine wear and increase tractor life.
Description
(1) technical field
The utility model relates to a kind of tractor steering device, is specifically related to a kind of before driving four-wheeled tractor damping steering hardware.
(2) technical background
The before driving four-wheeled tractor formula steering hardwares of bowing that adopt more, when turning to, preceding half frame is rotated together with the diesel engine on it, regulating mechanism, turns to effort, and the complete machine straight motion stability is relatively poor, is difficult to accurate control when turning to, and safety is relatively poor.The trac. diesel engine chassis of this structure directly is fixed on the propons, and full car shakes strongly when travelling, and chaufeur works long hours and is difficult to stand, and causes machine members to reduce service life easily, also influences the steady safety of institute's cargo.Travel at secondary road, serious because of jolting, also can cause roll-over accident.
(3) utility model content
The purpose of this utility model is design a kind of before driving four-wheeled tractor damping and front-wheel steering device.
The utility model design-calculated before driving four-wheeled tractor damping steering hardware, comprise diesel engine, chassis, propons, operator's saddle, compartment, mechanical type direction machine, front and back four-wheel, front propeller shaft is two semiaxis, be hinged by Rzeppa joint A and output shaft of gear-box respectively, the two front-wheels wheel beam warp Rzeppa joint B and the semiaxis other end are hinged.Direction machine pull bar is connected with steering swivel on the front wheel hub, turns to synchronizing bar to connect left and right sides wheel hub.Diesel engine is fixed on the chassis, is connected for spring between chassis and the propons.
Because of between front-wheel wheel shaft and the semiaxis Rzeppa joint being arranged, each mechanism of direction of passage machine when bearing circle rotates, pull bar can spur front wheel hub, changes front-wheel and half interaxle angle, reaches the purpose that turns to, and turns to synchronizing bar to keep left and right wheels steering angle unanimity.Because of between semiaxis and the output shaft of gear-box Rzeppa joint being arranged, when the injustice front-wheel bob of ground, semiaxis can be swung on vertical surface, has reduced the vibrations of car load.Simultaneously, because of between diesel engine chassis and the propons spring being arranged, the vibrations when having significantly reduced the diesel engine operation have also been cut down the influence of Uneven road to vehicle body to the influence of car load.
Advantage of the present utility model is: 1 turns to flexibly easy operating; 2 driving stabilities, the crossing ability rectilinearity is good, and is safe and reliable; 3 give full play to diesel engine power, and hill climbing ability strengthens; 4 have alleviated the vibrations of trac. greatly, drive comfortable light; 5 are applicable at the relatively poor road driving in rural area and mountain area; 5 have reduced component wear because of alleviating vibrations, have improved trac. service life.

(5) specific embodiment
This before driving four-wheeled tractor damping steering hardware embodiment 1 as shown in Figure 1, 2, comprise diesel engine 1, chassis 6, propons 3, operator's saddle, compartment, mechanical type direction machine, front and back four-wheel, front propeller shaft is two semiaxis 12, be hinged by Rzeppa joint A10 and change speed gear box 7 output shafts respectively, two front-wheels 4 take turns beam warp Rzeppa joint B11 and semiaxis 12 other ends are hinged.Direction machine pull bar 9 is connected with steering swivel on front-wheel 4 wheel hubs, turns to synchronizing bar 8 to connect left and right sides front-wheel 4 wheel hubs.Spring between chassis 6 and the propons 3 be about two longitudinal leaf springs 2, the chassis is fixed in 6 times in the arc of steel spring 2 top, two ends of arc are fixed on the propons 3.
Below, steel spring 2 middle parts, fixing recoil glue 5 on propons 3.When vibrations are serious, steel spring 2 is descending when too much, recoil glue 5 jack-up steel springs 2 are avoided shaking excessive, also avoid steel spring 2 compressing semiaxis 12.
This before driving four-wheeled tractor damping steering hardware embodiment 2 is shown in Fig. 3,4, and the spring between chassis 6 and the propons 3 ' is a spiral spring 2 '.One end and the chassis 6 of L shaped movable propons 3 ' are hinged, the other end and the chassis 6 of spiral spring 2 ' connection activity propons 3 '.
