Abstract
The invention discloses a bidirectional fixing type pin shaft assembly of a steering transverse tie rod for a large-sized mine self-discharging car, which belongs to the technical field of self-discharging cars. The pin shaft assembly comprises an end cover, a steering transverse rod assembly, an oil cup, a retainer ring, a steering knuckle arm, bolts, a steering rocking arm, a conical pin shaft, a check washer and a ball oscillating bearing; the end cover and the check washer are fixed on the conical pin shaft; the upper part of the conical pin shaft is a pin shaft big head; a lower head of the conical pin shaft has a conical degree; an upper head of the conical pin shaft is connected with the transverse tie rod assembly through the ball oscillating bearing; the lower head of the conical pin shaft is matched with the surface with the same conical degree of the steering rocking arm through a surface with a conical degree; and an inner groove of the end cover is mounted clinging to the upper surface and the lower surface of the conical pin shaft. The pin shaft assembly has the beneficial effects that a shaft hole is difficult to become big and deform in the relative friction between the steering transverse tie rod of the self-discharging car with electric wheels and the steering rocking arm as well as between the steering transverse tie rod and the steering knuckle arm; the wear service life of a pin shaft is long; and the running is safe.
Description
Technical field
The present invention relates to a kind of composition accessory of electric drive wheel quarry tipper, relate in particular to the two-way fixed type bearing pin of a kind of large-scale mine dumping car tierod assembly, belong to the dumping car technical field.
Background technology
The two-way fixed type bearing pin of tierod is one of vitals in the automobile steering system tie rod assembly.The performance of bearing pin assembly can comparatively directly have influence on the performance of whole steering swivel system.
In automotive operation, the force rate that the bearing pin assembly generally bears is bigger.In use, can produce the gap between the ball seat of longitudinal joints and the bulb.Along with the prolongation ball seat of period of service and the gap between bulb also can be strengthened thereupon.The space that the generation meeting in gap is reserved vibration and rocked to bulb, along with the expansion in gap, the Oscillation Amplitude of bulb and shaking amplitude are also just big more in the use.The stability of longitudinal joints, alerting ability, accuracy of action also just decrease, and then cause whole steering swivel system performance decrease.
Growth along with domestic and international mining amount; Quarry tipper develops towards the large-tonnage direction; Because the quarry tipper tonnage is big; The mine; The environment and the road conditions of irrigation site are more abominable; Stressed more complicated; The reliability of vehicle is even more important, and the deadweight of large-scale mine dumping car is very big, and vehicle is in operation and jolts; The be hit effect of power of axle cap; Get loose gradually, make bearing pin in the axis hole of shift fork, both produce axial motion, produce circular movement and radial motion again; Produce friction relatively; Cause the axis hole wearing and tearing to become big; Distortion, the axle wearing and tearing make bearing bear bigger impulsive force so again; Make the lost of life of bearing; Because axis hole becomes big with the tolerance clearance of axle, and the play motion of sense of motion is increased, and influences traffic safety.
Summary of the invention
Problem to above-mentioned prior art existence; The present invention provides the two-way fixed type bearing pin of a kind of large-scale mine dumping car tierod assembly; Be difficult for making axis hole to become big, distortion when having the relative friction of electric power wheel self-discharging vehicle tierod and pitman arm, tierod and track arm, pivot pin wearing and tearing long service life, the advantage of traffic safety of improving.
To achieve these goals; The technical scheme that the present invention adopts is: the two-way fixed type bearing pin of a kind of large-scale mine dumping car tierod assembly; Comprise end cap; The tierod assembly; Lubricating cup; Back-up ring; Track arm; Bolt and pitman arm; The left intermediate rod nipple of tie rod assembly is connected with track arm; Right intermediate rod nipple is connected with pitman arm; End cap and check washer are fixed on the taper bearing pin; Also comprise taper bearing pin and ball joint bearing; The top of taper bearing pin is the bearing pin major part; Following has tapering the taper bearing pin; The taper bearing pin the higher authorities be connected with tie rod assembly through ball joint bearing; Following matches the taper bearing pin with the face of the identical tapering of pitman arm through the face that has tapering, and the end cap inside groove is close to taper bearing pin upper and lower surface and is installed; The bending of check washer outward flange, check washer are installed in the end cap upper end, and end cap and check washer are through being bolted on the taper bearing pin.
End cap and check washer are to be 120 ° be bolted on the taper bearing pin by 3.
A lubricating cup is installed in the side of tierod assembly.
The bending of check washer outward flange.
The invention has the beneficial effects as follows: the electric power wheel self-discharging vehicle tierod is relative with pitman arm, tierod and track arm to be difficult for making when rubbing axis hole to become big, distortion, wearing and tearing, pivot pin long service life, traffic safety.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 connects front schematic view A for the tierod among the present invention with track arm;
Fig. 3 connects schematic rear view B for the tierod among the present invention with pitman arm.
Among the figure: 1, taper bearing pin, 2, end cap, 3, check washer, 4, the tierod assembly, 5, lubricating cup, 6, ball joint bearing, 7, back-up ring, 8, track arm, 9, bolt, 10, pitman arm.
The specific embodiment
To combine accompanying drawing that the present invention is described further below.
Like Fig. 1; Fig. 2 and shown in Figure 3; The present invention includes end cap 2; Tierod assembly 4; Lubricating cup 5; Back-up ring 7; Track arm 8; Bolt 9 and pitman arm 10; The left intermediate rod nipple of tie rod assembly 4 is connected with track arm 8; Right intermediate rod nipple is connected with pitman arm 10; End cap 2 is fixed on the taper bearing pin 1 with check washer 3; Also comprise taper bearing pin 1 and ball joint bearing 6; The top of taper bearing pin 1 is the bearing pin major part; Following has tapering taper bearing pin 1; Taper bearing pin 1 the higher authorities are connected with tie rod assembly 4 through ball joint bearing 6; Following matches taper bearing pin 1 with the face of the identical tapering of pitman arm 10 through the face that has tapering, and end cap 2 inside grooves are close to taper bearing pin 1 upper and lower surface and are installed; Check washer 3 outward flange bendings, check washer 3 is installed in end cap 2 upper ends, and end cap 2 is fixed on the taper bearing pin 1 through bolt 9 with check washer 3; End cap 2 is to be fixed on the taper bearing pin 1 by 3 bolts 9 that are 120 ° with check washer 3; The two-way fixed type bearing pin of a kind of large-scale mine dumping car tierod according to claim 1 assembly is characterized in that a lubricating cup 5 is installed in the side of said tierod assembly 4; Check washer 3 outward flange bendings.
After the installation of the present invention, taper bearing pin 1 top and following because all with check washer 3 bendings prevents bolt looseness; Because taper bearing pin 1 has tapering; Increased the area of contact of bearing pin and pitman arm or track arm; Be more conducive to stressed; And bearing pin top is oscillating bearing 6; Can reduce the friction of bearing pin and intermediate rod; Be difficult for making axis hole to become big, distortion, pivot pin long service life, traffic safety when making the relative friction of electric power wheel self-discharging vehicle tierod and pitman arm, tierod and track arm.
