Description
Technical field
This utility model is specifically related to a kind of tractor steering drive axle steering knuckle structure, belongs to Tractor Driving Axle and manufactures field.
Background technology
During tractor work, knuckle is the important feature of tractor steering, and the quality of steering knuckle performance directly decides tractor steering performance and used life.
During Tractor Driving Axle manufactures, need the axle center ensureing upper and lower two knuckle pin-and-holes to keep consistent, for reducing difficulty of processing, two pin-and-holes are made through hole.Drive axle assembling uses the top in the bottom of upper pin-and-hole, lower pin-and-hole to arrange port lid, on upper pin-and-hole top, lower pin-and-hole bottom mode that oil sealing is set knuckle is sealed, knuckle spindle is connected cooperation by rolling bearing with pin-and-hole foundation.
The pressure that wherein port lid relies on bearing to give is fitted with front axle housing, but sets up the most fixing connection with front axle housing.During tractor work jolts, rolling bearing can play, thus port lid and front axle housing produce gap, extraneous muddy water etc., and foreign material just can enter in pin-and-hole.
Wherein the play of rolling bearing also can cause the play of outer side seal, and restriction due to bulk typically can only arrange the outside framework oil seal of single port at knuckle position, thus causes the quality that seals and service life low, and sealing effectiveness is undesirable.
After having the foreign material such as muddy water to enter pin-and-hole, the abrasion of rolling bearing will greatly speed up, the gap of rolling bearing becomes big, tractor pitches in operation, swing, cause and about knuckle spindle, beat bearing outer ring, owing to bearing outer ring hardness is high, pin-and-hole is widened ovalisation, thus causes front driving axle to turn to malfunctioning or yaw.
Summary of the invention
Present invention aims to that the Tractor Driving Axle steering knuckle described in background technology is of poor quality, service life is short, drive axle turns to malfunctioning or pendulum first order issue, provide a kind of tractor steering drive axle steering knuckle structure, to improve the sealing property of knuckle, extend the service life of knuckle.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that:
The present invention program: a kind of tractor steering drive axle steering knuckle structure, it is mainly made up of front axle housing, knuckle, knuckle spindle, lining, spherical bearing, sliding bearing, circle shrouding, disk spring, sunk screw, fastening bolt etc..There are two concentric upper and lower pin-and-holes described front axle housing one end, upper and lower lining it is respectively provided with in upper and lower pin-and-hole, knuckle spindle is divided on knuckle pin and knuckle downside pin, sell on knuckle and be arranged in upper lining by sliding bearing, knuckle downside pin is arranged in lower lining by spherical bearing, and knuckle is connected by fastening bolt I and fastening bolt group II group are fixing respectively with pin, knuckle downside pin on knuckle；Described disk spring is divided into disk spring and lower disk spring, and upper disk spring is positioned on knuckle at the median surface of pin and upper lining, and lower disk spring is positioned at the median surface of knuckle downside pin and lower lining；Described upper and lower round shrouding lays respectively at lower surface and the upper surface of lower pin-and-hole of pin-and-hole on front axle housing, and upper and lower round shrouding has counter sink, is connected by sunk screw group I and sunk screw group II are fixing with front axle housing respectively.
Wherein, the upper and lower pin of described knuckle is connected via fastening bolt group and knuckle are fixing respectively, can be rotated in upper pin-and-hole by pin on sliding bearing knuckle, can be rotated in lower pin-and-hole by spherical bearing knuckle downside pin, knuckle upper and lower pin can drive knuckle to rotate when rotating, thus completes the steering procedure of tractor.
Improving as one, described upper lining is arranged in pin-and-hole and for interference fit, and sliding bearing swelling is in upper lining, and on knuckle, pin can relatively rotate with sliding bearing.
Improving as one, described lower lining is arranged in lower pin-and-hole and for interference fit, and Internal Spherical Surface bearing is arranged in lower lining, is interference fit with lower lining；Bearing with spherical outside surface is arranged on knuckle downside pin one end, and keeps interference fit with knuckle downside pin；Internal and external spherical surfaces bearing can relatively rotate.
Improve as one, described upper disk spring is arranged on knuckle between pin and upper lining, and bear certain precompression, spring upper end face keeps stable laminating with knuckle spindle end face, lower surface with upper bush end face, can effectively stop that external impurities enters in pin-and-hole.
Improving as one, described lower disk spring is arranged between knuckle downside pin and lower lining, and bears certain precompression, and spring upper end face keeps stable laminating with lower bush end face, lower surface with knuckle downside pin end face.
Improving as one, described round shrouding, upper round shrouding is positioned at pin-and-hole bottom, and lower round shrouding is positioned at lower pin-and-hole top, and upper and lower round shrouding has three uniform countersunk head through holes, and circle shrouding is connected via sunk screw group and front axle housing are fixing.Thus, upper round shrouding encloses the lower surface of pin-and-hole, and lower round shrouding encloses the upper surface of lower pin-and-hole.
Beneficial effect
Owing to have employed technique scheme, the play of sliding bearing and spherical bearing is little, tractor jolts in operation, vibrate during, the play of free bearing is less, will not produce the imagination tapping pin-and-hole, and the sealing of knuckle is improved.
Owing to the external impurities such as upper round shrouding encloses the lower surface of upper pin-and-hole, and lower round shrouding encloses the upper surface of lower pin-and-hole, muddy water can not enter in pin-and-hole via upper pin-and-hole lower end, lower pin-and-hole upper end again, the sealing of knuckle is guaranteed.
Owing to upper disk spring is arranged on knuckle between pin and upper lining, lower disk spring is arranged between knuckle downside pin and lower lining, and two disk springs all bear certain precompression, even if so when free bearing has certain play, two disk spring end faces can coordinate the laminating that face holding is stable with it, thus ensures the reliability of steering knuckle performance.
