The utility model discloses only with the connection problem of a connecting pin roll with regard to having solved knuckle arm, steering cylinder and tie rod, simultaneously, solved that produce wearing and tearing and the clearance cooperates the not hard up condition because of round pin axle and shaft hole, improved steering mechanism's sensitivity, accuracy and stability.
Description
Technical field
This utility model relates to a kind of bearing pin assembly, a kind of three-dimensional fixed pin shaft assembly for quarry tipper, belongs to bearing pin assembly technical field.
Background technology
Along with the surge of domestic and international mining amount, quarry tipper develops towards large-tonnage direction, has the most reached load-carrying about 400 tons.In addition mine environment is severe and road conditions are complicated, and the requirement to front axle of mining dump truck steering mechanism is more and more higher.The quality of steering mechanism determines reliability and the service life of vehicle.Track rod three-dimensional fixed pin shaft is connected to knuckle arm, steering cylinder and track rod, is ingredient important in steering, and its performance directly determines the performance quality of steering mechanism.
In the steering procedure of mine car, bearing pin assembly load subjected to is bigger, plus mine rugged environment and road conditions, bearing pin and axis hole easily produce quite motion, produce abrasion and gap, causing the vibration of steering mechanism and rock, the susceptiveness of steering mechanism, accuracy and stability decline accordingly, affect the security performance of car load.
Summary of the invention
The problem existed for above-mentioned prior art, this utility model provides a kind of three-dimensional fixed pin shaft assembly for quarry tipper, the connection of knuckle arm, steering cylinder and track rod is realized with minimum bearing pin, the situation of matching loose because bearing pin and axis hole produce abrasion and gap can be solved, the susceptiveness of steering mechanism, accuracy and stability can be improved.
To achieve these goals, a kind of three-dimensional fixed pin shaft assembly for quarry tipper that this utility model uses, including connecting bearing pin, connecting bolt, slotted nut, spacer and hubcap, described connection bearing pin is logical bearing pin in being, the two ends up and down connecting bearing pin are mounted on hubcap；Connecting bolt from top to bottom through connecting bearing pin and the hubcap at two ends thereof, and with slotted nut with the use of, it is achieved connect bearing pin and be connected with the fixing of hubcap；Connect the upper end of bearing pin, middle-end and lower end can corresponding with steering cylinder pull bar, knuckle arm and track rod connect；Spacer is enclosed within connection bearing pin and tightens by knuckle arm.
The upper end of described connection bearing pin is connected with steering cylinder pull bar by oscillating bearing I；The middle-end connecting bearing pin is the pyramidal structure matched with taper hole in knuckle arm；The lower end connecting bearing pin is connected with track rod by oscillating bearing II.
Also include with connecting bolt, slotted nut with the use of pad.
Compared with prior art, this utility model only just solves the connectivity problem of knuckle arm, steering cylinder and track rod with a connection bearing pin；Meanwhile, solve the situation of matching loose because bearing pin and axis hole produce abrasion and gap, improve the susceptiveness of steering mechanism, accuracy and stability.
Accompanying drawing explanation
Fig. 1 is that this utility model uses view；
Fig. 2 is structural representation of the present utility model.
In figure: 1, knuckle arm, 2, three-dimensional fixed pin shaft assembly, 3, steering cylinder pull bar, 4, track rod, 5, oscillating bearing I, 6, oscillating bearing II, 21, connecting bolt, 22, hubcap, 23, connect bearing pin, 24, spacer, 25, slotted nut.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of three-dimensional fixed pin shaft assembly for quarry tipper, including connecting bearing pin 23, connecting bolt 21, slotted nut 25, spacer 24 and hubcap 22, described connection bearing pin 23 is logical bearing pin in being, the two ends up and down connecting bearing pin 23 are mounted on hubcap 22；Connecting bolt 21 from top to bottom through connecting bearing pin 23 and the hubcap 22 at two ends thereof, and with slotted nut 25 with the use of, it is achieved connect bearing pin 23 and be connected with the fixing of hubcap 22；Connect the upper end of bearing pin 23, middle-end and lower end can corresponding with steering cylinder pull bar 3, knuckle arm 1 and track rod 4 connect；Spacer 24 is enclosed within connection bearing pin 23 against knuckle arm 1.
The upper end of described connection bearing pin 23 is connected with steering cylinder pull bar 3 by oscillating bearing I5；The middle-end connecting bearing pin 23 is the pyramidal structure matched with taper hole in knuckle arm 1；The lower end connecting bearing pin 23 is connected with track rod 4 by oscillating bearing II6.
Also include with connecting bolt 21, slotted nut 25 with the use of pad, pad set up the steadiness that can improve connection, thus improve the stability of whole bearing pin assembly.
During use, steering cylinder pull bar 3, knuckle arm 1 and track rod 4 can be installed successively according to structure as shown in Figure 1.In quarry tipper running, because of the severe of road conditions and the thrust of steering cylinder pull bar, the taper hole connecting bearing pin 23 and knuckle arm 1 easily produces abrasion, thus produces gap, oscillation phenomenon occurs.But being taper owing to connecting bearing pin 23 mid portion, after producing gap, whole connection bearing pin 23 can reduce the gap connecting bearing pin 23 with knuckle arm 1, it is to avoid produce excessive vibration toward declining.
From said structure, this utility model is arranged by simple structure, it is connected to knuckle arm, steering cylinder and track rod with minimum bearing pin, and solve the oscillation phenomenon occurred because bearing pin produces abrasion with knuckle arm taper hole, improve the susceptiveness of steering mechanism, accuracy and stability.
