Abstract
The utility model relates to a steering gear for roller tractor, being applicable to the roller tractor running on roads in a poor condition of the countryside and mountainous areas. The main structure comprises a protocerebral pulling tractor (1), rear dolly (2), slewing journal (3), turning lever (4) and the like, two locating studs (6, 7) are arranged in the joint of the transmission fork and the rotating shaft for slewing journal (5).The protocerebral pulling tractor (1) is hinged in the transmission fork of the slewing journal (3) through the main pin (8). In a position of the rear dolly near the slewing journal, a block is arranged between two locating studs (17). The utility model can turn smoothly and is easy to handle, comfortable to drive, applicable to reduce the probability of overturning accident.
Description
Technical field
The utility model belongs to the parts of farm tractor.Be specifically related to a kind of steering hardware of disc type trac..
Background technology
The before driving four-wheel disc type trac. of the prior art formula steering hardwarees of bowing that adopt more, the diesel engine chassis directly is fixed on the propons, connecting bridge adopts the steering ball joint, its structure is a suit bulb in the bulb mounting, the clamp nut that spins in the vertical shaft on bulb top upper end, spring cotter locks clamp nut.Manual draw bar is screwed on the screw rod on the bulb mounting sidewall, and bulb vertical shaft and steering hardware join.Pull pull bar, bulb vertical shaft control steering hardware is rotated, trac. turns to thereupon.When pull bar was motionless, trac. should keep stable craspedodrome state.But because farm tractor front axle rotates together with the diesel engine on it, regulating mechanism, turn to effort, and the vertical shaft in the steering ball joint supports because of no mechanism, thereby trac. travels on uneven secondary road and can side direction rock, and thisly rock moving will also can cause roll-over accident in case surpass the gravity balance point of farm tractor front axle, bring adverse effect for stable the travelling of trac..
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, and a kind of steering hardware that is suitable for the disc type trac. of use on trac., flexible operation, driving safety is provided.
The utility model is achieved in that a kind of steering hardware of disc type trac., comprise propons drawing head, back axle traction seat, steering swivel, turn to connecting lever etc., turn to the fulcrum of connecting lever to connect steering swivel, the pull bar of connecting lever termination direction machine, it is characterized in that: steering swivel one end is fork and dials shape, the other end is rotating shaft, and pitching the junction of dialling with rotating shaft has two locating dowel pins; In the fork that the propons drawing head is hinged on steering swivel by stub, dull and stereotyped bearing is dialled; The rotating shaft end of steering swivel inserts in the back axle traction seat and is connected with jam nut, and cone bearing assembly and oil sealing are arranged in the back axle traction seat; Described back axle traction seat has been located block (17) by between two locating dowel pins of steering swivel, and the other end has end cap.
Compare with existing small four-wheel tractor, the utility model is used for connecting propons and back axle on the disc type trac., and the pull bar of direction of passage machine can spur connecting lever when bearing circle rotates, and changes the angle of bowing of propons and back axle, reaches the purpose that turns to.Propons drawing head of the present utility model and steering swivel all are equipped with bearing between steering swivel and the back axle traction seat, turn to flexibly, and rapid operation is driven comfortable light.In addition, two locating dowel pins of steering swivel have limited the windup-degree of back axle traction seat, the gravity balance point that can not surpass farm tractor front axle is moved in rocking of being produced when the injustice front-wheel bob of ground, can avoid roll-over accident, guaranteed that the stable of trac. travels, be specially adapted at the relatively poor road driving in rural area and mountain area.
