Abstract
The utility model discloses a leveler front axle steering mechanism, which is composed of a left knuckle, a left steering arm, a front axle body, a left ball pivot, a steering drawbar, a drawbar ball pivot connection seat, a steering oil cylinder, a right ball pivot, a right knuckle, a knuckle spindle, a right steering arm and a hub. The left knuckle, the right knuckle, the knuckle spindle, the needle bearing and the hub are installed in turn on the front axle body; the left ball pivot, the right ball pivot, the clamp ring and the drawbar ball pivot connection seat are installed in turn on the steering drawbar. Left and right ball pivots on both sides are inserted into a taper pin-hole of the left and the right knuckle and are fixed with a slotted nut and a splint pin; end of the double-piston lever of the steering oil cylinder is connected with a permanent seat on the front axle body by abolt; a ball pivot pin in middle of the steering oil cylinder is connected with a ball pivot connection seat in middle of the steering drawbar. All of the above forms the steering mechanism of a single oil cylinder driving front axle. The utility model is simple in structure, which can simplify the structure and cut the manufacture cost by connecting a double acting single oil cylinder ball pivot with the steering mechanism.
Description
Technical field the utility model is a kind of later-model road grader Front Axle Steering Mechanism.
The background technology propons is one of critical component of road grader, and its effect is a support frame; Utilize steering hardware to make wheel deflection certain angle, to realize turning to of road grader.The Front Axle Steering Mechanism of present homemade road grader all is to adopt two oil cylinder symmetric arrangement, want strict control position tolerance grade in processing, the fitting process, otherwise the both sides wheel turning angle can't be coordinated.For the deficiency of the Front Axle Steering Mechanism that overcomes existing road grader, the utility model provides a kind of later-model road grader Front Axle Steering Mechanism, to reach simplified structure, reduces the manufacturing cost purpose.
The summary of the invention the purpose of this utility model provides a kind of later-model road grader Front Axle Steering Mechanism.The purpose of this utility model be achieved in that this steering hardware by left steering joint, left steering arm, fluted nut, spring cotter, preceding pontic, left ball pivot, steering track rod, drag link ball hinge joint chair, turn to oil cylinder, bolt, clamping ring, right ball pivot, right steering joint, needle bearing, knuckle pivot pin, right steering arm, wheel hub etc. to form.On the preceding pontic left steering joint, right steering joint, knuckle pivot pin, needle bearing, wheel hub are housed successively.Left ball pivot, right ball pivot, clamping ring, drag link ball hinge joint chair are housed on the steering track rod successively, and the left and right ball pivot at two ends inserts the taper pin-hole of left and right spindle arm respectively and fixes with fluted nut, spring cotter.Turn to the end of double piston-rod of oil cylinder and the permanent seat bolt together on the preceding pontic, turn to the ball joint stud at oil cylinder middle part to be connected with ball pivot Connection Block in the middle part of the steering track rod.So just realized single hydraulic oil cylinder driving Front Axle Steering Mechanism.The utility model is simple in structure, and it can reach simplified structure by using the single oil cylinder ball pivot of double acting to connect steering hardware, reduces the manufacturing cost purpose.
The described oil cylinder that turns to is double acting, the double rod cylinder of cylinder barrel middle part dribbling hinge pin.
Described drag link ball hinge joint chair is the ball pivot Connection Block that is assemblied in the steering track rod middle part.
The utility model is described in further detail below in conjunction with drawings and Examples for description of drawings.
Fig. 1 is the constructional drawing of present embodiment;
Fig. 2 is the constructional drawing of present embodiment.
Pontic 12. bolts 13. right steerings saved 14. right steering arms, 15. needle bearings, 16. knuckle pivot pins, 17. wheel hubs before 1. fluted nuts, 2. spring cotters, 3. left ball pivot 4. steering track rods 5. drag link ball hinge joint chairs 6. turned to oil cylinder 7. clamping rings 8. right ball pivot 9. left steerings to save 10. left steering arms 11. among the figure
Left steering joint (9), right steering joint (13), knuckle pivot pin (16), needle bearing (15), wheel hub (17) are housed on the pontic (11) before the specific embodiment successively.Left ball pivot (3), right ball pivot (8), clamping ring (7), drag link ball hinge joint chair (5) are housed on the steering track rod successively, and the left ball pivot (3) at two ends and right ball pivot (8) insert the taper pin-hole of left steering arm (10), right steering arm (14) respectively and fix with fluted nut (1), spring cotter (2).Turn to the end of double piston-rod of oil cylinder (6) and the permanent seat bolt together on the preceding pontic, turn to the ball joint stud at oil cylinder middle part to be connected with ball pivot Connection Block (5) in the middle part of the steering track rod.By above installation, finish present embodiment.
Claims (3)
1. later-model road grader Front Axle Steering Mechanism is by preceding pontic, left and right sides steering swivel, knuckle pivot pin, needle bearing, wheel hub, steering track rod, left and right sides ball pivot, clamping ring, drag link ball hinge joint chair, left and right sides spindle arm, turn to oil cylinder to form; It is characterized in that: turn to the end of double piston-rod of oil cylinder and the permanent seat bolt together on the preceding pontic, turn to the ball joint stud at oil cylinder middle part to be connected, form the single oil cylinder ball pivot connection of double acting steering hardware with the ball pivot Connection Block at steering track rod middle part.
