Abstract
The utility model relates to a steering drive assembly for a front independent suspension frame of a farm automobile with four wheels. A steering knuckle casing is connected with a spherical support base through a main pin, the spherical support base is fixed to a steering knuckle support post of which both ends are respectively connected with an upper swinging arm and a lower swinging arm of an independent suspension frame, and the center of a universal joint of a cross shaft type is positioned on the shaft line of the main pin. Compared with the universal joint with constant velocity of a ball fork type, the utility model has the advantages of simple structure and low cost, and the influence can be ignored for farm automobiles.
Description
The utility model relates to a kind of independent front suspension with turning to the driving assembly, particularly be applicable to front-wheel adopt independent suspension structure the light four-wheel farm vehicle turn to the driving assembly.
Traditional three-wheel and four-wheel farm vehicle all adopt the layout of front-wheel steering, back-wheel drive, 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 road-holding property of this structure is relatively poor, and because the bel-drivenn width between centers is subjected to the influence of wheel bounce, neglects tight neglecting and relax, and has significantly increased the wearing and tearing and the loss in efficiency of belt, has also reduced the riding comfort of vehicle simultaneously.For overcoming above-mentioned shortcoming, Chinese patent 98200331.5,98202748.6,98202749.4 has proposed the four-wheel farm vehicle technical scheme of three kinds of novelties, core is to adopt the front-wheel steering of independent suspension structure to drive design, major part and assembly are selected the standardized product of existing jeep, minicar, farm vehicle for use, improve road-holding property and power-handling capability, thoroughly solved the belt-driving quality problems.Its front wheel knuckle and universal-joint use the local assembly of Beijing jeep BJ212, and the structure of Weiss universal joint and manufacturing process are comparatively complicated, and cost is higher.
The purpose of this utility model provides the light four-wheel farm vehicle that a kind of suitable front-wheel adopts independent suspension structure, simple in structure, the lower-cost driving assembly that turns to.
The purpose of this utility model is achieved in that on the basis that turns to the driving assembly of Beijing jeep BJ212, replaces Weiss universal joint with simple in structure, lower-cost cardan universal joint.
In the independent front suspension structure, because the also corresponding assembling cardan universal joint of combination transmission gearbox clutch end, and combination transmission gearbox output shaft is level, the variable speed effect basic neutralisation of cardan universal joint during the vehicle straight-line travelling with outer semiaxis.Because the farm vehicle moving velocity is not high, speed is lower when particularly turning to, and therefore uses the Weiss universal joint of the cardan universal joint replacement constant speed of variable speed, and is very little to the influence of farm vehicle, can ignore.
The utility model is described in further detail below in conjunction with Figure of description and embodiment.
Fig. 1 is the part sectional view of embodiment 1.
Fig. 2 is the part sectional view of embodiment 2.
1. jack shafts, 2. universal-joints, 3. spherical bearings, 4. stubs, 5. track arms, 6. steering swivel housings, 7. outer semiaxis 8. wheel hubs 9. steering swivel axle journals 10. flanges 11. steering swivel pillars 12. cardan universal joints 13. center support bearings among the figure
The utility model mainly is made of parts such as inner shaft (1), universal-joint (2), spherical bearing (3), stub (4), track arm (5), steering swivel housing (6), outer semiaxis (7), wheel hub (8), steering swivel axle journal (9), steering swivel pillars (11).
Because the combination transmission gearbox is fixed on the vehicle frame, in the vehicle ' process, inner shaft (1) will form the relative motion of vertical direction with spherical bearing (3), steering swivel pillar (11).In embodiment shown in Figure 11, spherical bearing (3) and steering swivel pillar (11) can provide the space of enough inner shaft (1) bob.Steering swivel housing (6) links together by stub (4) with spherical bearing (3), track arm (5) is fixed on the top of steering swivel housing (6), spherical bearing (3) is fixed on the steering swivel pillar (11), and the two ends of steering swivel pillar (11) are connected with the pumping arm action of independent suspension respectively.The nested wheel hub of steering swivel axle journal (9) outer rim (8), the outer semiaxis (7) of in-to-in is connected with wheel hub (8) by flange (10), on the axis that is centered close to stub (4) of universal-joint (2), and inner shaft (1), outer semiaxis (7) is linked together.Like this, Ackermann steer angle, wheel hub (8) rotates a certain angle around stub (4), and driving torque passes to wheel hub (7) via inner shaft (1), universal-joint (2), outer semiaxis (7), flange (10).
The local assembly of the utility model and Beijing jeep BJ212 compares, and main difference is the axle tube that has been replaced propons by steering swivel pillar (11), replaces Weiss universal joint by cardan universal joint (2).
In embodiment shown in Figure 22, spherical bearing (3) can not provide enough mobile spaces of inner shaft (1) with steering swivel pillar (11).At this moment, on the basis of embodiment 1, inner shaft (1) need be divided into two sections, and two sections also connect by cardan universal joint (12), and going up at steering swivel pillar (11) simultaneously increases a center support bearing (13).
Claims (3)
1. a four-wheel farm vehicle independent front suspension is with turning to the driving assembly, steering swivel shell (6) links together by stub (4) with spherical bearing (3), track arm (5) is fixed on the top of steering swivel housing (6), spherical bearing (3) is fixed on the steering swivel pillar (11), the two ends of steering swivel pillar (11) are connected with the pumping arm action of independent suspension respectively, the nested wheel hub of steering swivel axle journal (9) outer rim (7), the outer semiaxis (7) of in-to-in is connected with wheel hub (8) by flange (10), on the axis that is centered close to stub (4) of universal-joint (2), and with inner shaft (1), outer semiaxis (7) links together, and it is characterized in that universal-joint (2) is a cardan universal joint.
2. the driving assembly that turns to according to claim 1 is characterized in that inner shaft (1) is a continuous rigid shaft, and spherical bearing (3) and steering swivel pillar (11) leave the space of inner shaft (1) bob.
3. the driving assembly that turns to according to claim 1 is characterized in that inner shaft (1) is divided into two sections, connects by cardan universal joint (12), and going up at steering swivel pillar (11) simultaneously increases a center support bearing (13).
