Abstract
The utility model provides a front suspension device of a tractor, which consists of a front shaft, a vertical shaft, plate springs, a direction-changing rocker arm and a direction-changing tension rod and is characterized in that the front shaft of the tractor is provided with a bracket, one end of the bracket is hinged with a frame of the tractor, the axial line of a gemel is parallel to the rear shaft of the tractor, the axle center of the gemel is arranged close to the midpoint of the motion path at the rear end of the direction-changing tension rod, the front suspension is elastically supported by two groups of plate springs which are vertically arranged, the movable connection is utilized between the two ends of the plate springs and the frame. When front wheels shake or are slant relative to the car body, the front shaft of the tractor swings around the gemel center; the distance between the front shaft of the tractor and a direction-changing machine is not changed or the relative displacement is small, thereby avoiding the automatic direction change in the front shaft or decreasing the angle of the automatic direction change, therefore, the car runs evenly and the accident caused by unstable direction is avoided. The filed operation has good linear property and saves fuel.
Description
Affiliated technical field
The utility model relates to a kind of field machine, especially can make the stable trac. front suspension apparatus that travels of wheel flutter.
Background technology
The small four-wheel tractor front-wheel that China recent years is produced adopts the laminated spring resilient mounting more.One end of laminated spring adopts hinge to connect with frame, and the other end adopts and slides or the fork connection.When trac. travels, when front-wheel jolts or two front-wheels during with respect to tilting of car body, for the mechanical type steering swivel system, the laminated spring distortion, cause producing relative displacement between trac. front axle and the steering box, front-wheel can automatic steering under the effect of steering side tube when bearing circle was motionless, and this just makes the vehicle ' irregularity, particularly might cause the accident because of the direction shakiness when the speed of a motor vehicle is very fast.
Summary of the invention
For solving that the trac. front-wheel jolts or the two front-wheels problem that vehicle ' irregularity or direction shakiness cause the accident during with respect to tilting of car body.The utility model provides a kind of trac. front suspension apparatus.Jolting when front-wheel or two front-wheels during with respect to tilting of car body, between trac. front axle and the steering box distance do not change or relative displacement very little.Thereby can avoid the front-wheel automatic steering, or reduce the automatic steering angle.
The technical scheme that the utility model technical solution problem is adopted is: study a kind of trac. front suspension apparatus, be characterized in: mounting bracket on the trac. front axle, one end of support and the frame of trac. are connected with hinge, the parallel axes of hinge is in the trac. rear axle, the shaft core position of said hinge be located at steering box under, front suspension adopts two groups of laminated springs vertically arranging to do resilient mounting, all adopts removable connection between the two ends of laminated spring and the frame.
Grasswort and tractor frame that said mobile connection can be the laminated spring two ends connect by rocker mechanism.
Said mobile connection also can be the laminated spring two ends by slider support on tractor frame.
Beneficial effect
The beneficial effects of the utility model are, trac. front axle and frame are hinged, and the hinge center is near the steering side tube rear end.When front-wheel jolts or two front-wheels during with respect to tilting of car body, the trac. front axle is swung around the hinge center.Between trac. front axle and the steering box distance do not change or relative displacement very little.Thereby can avoid the front-wheel automatic steering, or reduce the automatic steering angle.This just makes, and vehicle ' is smooth-going, easy driving also can avoid the direction shakiness to cause the accident.Farm work can keep good rectilinearity, simultaneously also can fuel saving.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the front view of embodiment 1, and Fig. 2 is the birds-eye view of embodiment 1, and Fig. 3 is the front view of embodiment 2, and Fig. 4 is the birds-eye view of embodiment 2;
1 bearing circle among the figure, 2 steering boxs, 3 rocking arms, 4 bearings, 5 longitudinal ties, 6 supports, 7 intermediate rods, 8 spindle arms, 9 steering levers, 10 preceding shaft stools, 11 front-wheels, 12 vertical shafts, 13 front axles, 14 laminated springs, 15 hangers, 16 frames, 17 driving engines, 18 slide blocks.
The specific embodiment
Embodiment 1:
As attached illustrated in figures 1 and 2, bearing circle (1), steering box (2) and rocking arm (3) are fixed by bolts on the frame (16) by the base on the steering box (2).The ball cover hinge is installed at the two ends of longitudinal tie (5), is connected between rocking arm (3) and the steering lever (9), and intermediate rod (7) passes through the spindle arm (8) of the ball cover hinge-coupled at two ends in left and right wheels.Below beam, fix 2 bearings (4) respectively for two of frame (16), fix 2 preceding shaft stools (10) respectively between the vertical shaft (12) at preceding shaft stool (10) two ends and laminated spring (14), two supports (6) are connected in respectively between the bearing (4) and preceding shaft stool (10) of both sides by the ball cover hinge.Front axle (13) can be swung around the hinge axis of bearing (4).Front axle (13) is fixed on the middle part of laminated spring (14), and the grasswort at laminated spring (14) two ends is hinged on the frame (16) by hanger (15).When front-wheel (11) when jolting laminated spring (14) deform two ends grasswort by hanger (15) but swing.Front axle (13) is around the hinge axis swing of bearing (4).Relative displacement between spindle arm (8) and the rocking arm (3) is very little, and trac. then can not produce automatic steering, thus the traffic safety that guarantees.
Embodiment 2:
As accompanying drawing 3 and shown in Figure 4, the basic structure of present embodiment is identical with embodiment 1, and its difference is, fixes a support (6) at the middle part of trac. front axle (13), and the other end of support (6) connects by universal-joint and tractor frame (16).The shaft core position of the lateral shaft of universal-joint is located near the mid point of steering side tube rear end path of motion.Laminated spring (14) two ends are supported on the tractor frame (16) by slide block (18).Can reach the purpose identical with embodiment 1.
Supporting way between laminated spring in embodiment 1 (14) and the frame (16) also can adopt the supporting way of embodiment 2, and the supporting way between laminated spring in embodiment 2 (14) and the frame (16) also can adopt the supporting way of embodiment 1.
Claims (3)
1, a kind of trac. front suspension apparatus, it is characterized in that: mounting bracket on the trac. front axle, one end of support and the frame of trac. are connected with hinge, the parallel axes of said hinge is in the trac. rear axle, the shaft core position of said hinge be located at steering box under, front suspension adopts two groups of laminated springs vertically arranging to do resilient mounting, all adopts removable connection between the two ends of laminated spring and the frame.
