Abstract
A steering set for agricultural trailer wheels comprises a front steering device and a rear steering device. The front steering device comprises a traction plate, a traction beam, and left and right pressure cylinders. The rear steering device comprises a front wheel steering assembly and a rear wheel steering assembly. The pressure cylinders in the front steering device are connected with a steering cylinder in the rear steering device through oil pipes. The steering set for agricultural trailer wheels has the advantages that when a tractor turns, the hydraulic cylinders move to drive the front and rear wheels of a trailer to turn; the defect that the front and rear wheels are driven to slip sidewise and turn is overcome, coefficient of friction between tires and ground is reduced, tire abrasion is reduced, the structure is simple, mounting and maintenance are facilitated, and driving safety of agricultural trailers is guaranteed.
Description
Technical field
The utility model relates to agricultural transporting machinery, especially a kind of steering hardware of farm cart wheel.
Background technology
A kind of " double-shaft agricultural trailer " (patent No. is 201020651945.7) authorized by State Intellectual Property Office, now authorizes.This application solved original farm cart be all single shaft, lifting capacity little, run into the easily deficiency such as overturning of hillside or rough road surface.But double-shaft agricultural trailer is Shortcomings still.Because two cover wheel hubs of double-shaft agricultural trailer are fixed-direction designs, in the time that tractor truck turns, trailer is passive to be turned to, the passive sideslip and steering of diaxon tire, and tire and ground friction coefficient strengthen, the safety of unfavorable tire used and vehicle.
Summary of the invention
The utility model is in order to overcome the deficiency of double-shaft agricultural trailer wheel hub fixed-direction design, a kind of tire steering hardware of farm cart is provided, in the time that front truck turns, by hydraulic cylinder, the wheel hub on twin shaft is turned simultaneously, reach and reduce tire and ground friction coefficient, reduce wear on tyres, guarantee vehicle driving safety.
The utility model solves the scheme of its technical matters, comprise front steering device, rear steering device, wherein, front steering device comprises towing plate, draw beam, two oil pressure cylinders in left and right, towing plate is T-shaped, the hydraulic stem of left and right in two oil pressure cylinders respectively with towing plate both sides coordination hinge, draw beam is fixed on vehicle frame, towing plate coordinates with draw beam front end, bearing pin is hinged, respectively there is an oil cylinder seat draw beam both sides, two oil pressure cylinders in left and right respectively with oil cylinder seat coordination hinge, rear steering device comprises front-wheel steering assembly and rear-axle steering assembly, rear-axle steering assembly is identical with front-wheel steering assembly structure and mounting process, take front-wheel steering assembly as example, front-wheel steering assembly comprises front axle, steering track rod, steering cylinder kingpin, there is axis hole at front axle two ends, one side has oil cylinder seat, front axle two ends axis hole coordinates with both sides kingpin respectively, kingpin and hub hinged, steering track rod two ends respectively with both sides hub hinged, hydraulic stem in steering cylinder and hub hinged, steering cylinder and oil cylinder seat are hinged, oil pressure cylinder in front steering device is connected by oil pipe with the front-and rear-wheel steer oil cylinder in rear steering device.
The beneficial effects of the utility model are, in the time that front truck turns, by hydraulic cylinder, the front and back wheel on trailer is turned, overcome the deficiency of the passive sideslip and steering of front and back wheel, reach and reduced tire and ground friction coefficient, reduced wear on tyres, simple in structure, be easy to installation and repairing, guarantee the beneficial effect of vehicle driving safety.
Accompanying drawing explanation:
With reference to the accompanying drawings the utility model is further illustrated.
Fig. 1. be the utility model topology view.
The specific embodiment:
The specific embodiment of the present utility model is to comprise front steering device, rear steering device, wherein, front steering device comprises towing plate, draw beam, two oil pressure cylinders in left and right, with reference to Fig. 1, towing plate 1 is T-shaped, two of left and right oil pressure cylinder 4, hydraulic stem 3 in 22, 23 respectively with towing plate 1 both sides coordination hinge, draw beam 7 is fixed on vehicle frame 9, towing plate 1 coordinates with draw beam 7 front ends, bearing pin 2 is hinged, respectively there is an oil cylinder seat 5 draw beam 7 both sides, 21, two of left and right oil pressure cylinder 4, 22 respectively with oil cylinder seat 5, 21 coordination hinges, rear steering device comprises front-wheel steering assembly and rear-axle steering assembly, and rear-axle steering assembly is identical with front-wheel steering assembly structure and mounting process, and take front-wheel steering assembly as example, front-wheel steering assembly comprises front axle 10, steering track rod 14, steering cylinder 18, kingpin 11, 15, there is axis hole at front axle 10 two ends, and a side has oil cylinder seat, front axle 10 two ends axis holes respectively with both sides kingpin 11, 15 coordinate, kingpin 11, 15 with wheel hub 12, 16 is hinged, steering track rod 14 two ends respectively with both sides wheel hub 12, 16 is hinged, and the hydraulic stem 17 in steering cylinder 18 is hinged with wheel hub 16, and steering cylinder 18 is hinged with oil cylinder seat, the oil pressure cylinder 4 in front steering device, 22 with rear steering device in front-and rear-wheel steer oil cylinder 18, 13 by oil pipe 6, 8, 19, 20 connect, the principle of work of the steering hardware of this farm cart wheel is: in the time of vehicle turnon left, hydraulic stem 23 on oil pressure cylinder 22 in front steering device compresses, hydraulic oil is compressed into steering cylinder 18 back cavities of rear steering device through oil pipe, at this moment the hydraulic stem 17 in steering cylinder 18 stretches out, and trailer wheels is turned left, simultaneously, hydraulic stem 3 on oil pressure cylinder 4 in front steering device stretches out, and hydraulic oil is through oil pipe 6, 8 enter rear-axle steering oil cylinder 13, and at this moment the hydraulic stem on rear-axle steering oil cylinder 13 is retracted, and pulls rear dragging wheel turning clockwise, on the contrary, in the time of vehicle right-hand corner, front trailer wheels turning clockwise, rear dragging wheel turns left.
