Abstract
The utility model discloses a steering pulling rod joint assembly for a farming vehicle, including a ball stud arranged in the steering pulling rod joint body. The lower bulb end of the ball stud is equipped with bowl-shaped body matching the bulb shape of the ball stud. The bulb upper end of the ball stud is equipped with a deep groove ball bearing. The inner wall surface shape of the bearing inner ring matches the bulb upper end of the ball stud. The bowl-shaped body is in contact with the internal surface of the ball stud. The bearing inner ring is in contact with the bulb upper end of the ball stud. The bottom part of a pinhole is equipped with an adjusting nut. Pressing springs are arranged among the upper part of the ball stud, the adjusting nut and the bowl-shaped body. The original point contact between a rolling body and the ball end is changed into surface contact. At the same time, a close surface contact is arranged between the bearing inner ring and the bulb upper end of the ball stud. Under the function of the upper and lower pressing springs of the ball stud, the origin of the ball-shaped body on the end of the ball stud is always on the axis of the steering pulling rod joint without easy deviation. The rotation is more flexible, the driving and the operation are more stable, and the maintenance cost and the transportation cost are lowered.
Description
Technical field
The utility model relates to Agricultural automotive vehicle, is specifically related to the steering track rod joint in the Agricultural automotive vehicle wheel steering device assembly.
Background technology
The Agricultural automotive vehicle that by the fraction horsepower diesel engine is power has obtained using very widely aspect many in agricultural production, transportation etc., is bringing into play positive and irreplaceable vital function in current Tendency of Agricultural Machinery in China process.But be applied at present adopt mostly in the steering track rod nipple pin axis hole in the Agricultural automotive vehicle wheel steering device assembly and fill out structures such as cover, slip cap, especially when uneven travels down, because it is structural unreasonable, make the steering track rod joint stressed bigger, ball end in the pin shaft hole is easy to depart from the pin shaft hole axis, cause the damage of filling out cover, slip cap and trip ring, have a strong impact on the ride comfort of vehicle simultaneously, the cruising of vehicle and operation caused have a strong impact on, increased the service expenditure expenditure again.
Summary of the invention
The utility model purpose is to provide a kind of and turns to flexibly, operates steadily, long-lived Agricultural automotive vehicle steering track rod connector assembly, to overcome the deficiency that the unreasonable project organization of prior art brings.
The utility model purpose realizes by following measure: this Agricultural automotive vehicle steering track rod connector assembly comprises the ball end that is assemblied in the steering track rod joint body, it is characterized in that lower end, described ball end bulb is equipped with the bowl bodies with ball end bulb form fit, upper end, ball end bulb assembling deep groove ball bearing, bearing inner ring internal face shape and upper end, ball end bulb coupling, running-fit between bearing inner ring and ball end, face contacts between bearing inner ring and ball end, the pin shaft hole bottom is equipped with adjustment nut, is fitted with stage clip between ball end top and adjustment nut and bowl bodies respectively.
Stage clip on the described ball end is preferably tower shape stage clip, when this tower shape stage clip is compressed, can make to combine closelyr between ball end and bowl bodies, can reduce the axial space that it occupies to greatest extent simultaneously.
The technological advance that the utility model is obtained: because with original cover of filling out in the steering track rod nipple pin axis hole, slip cap is used and the bowl bodies of ball end bulb form fit and the deep groove ball bearing replacement of mating with upper end, ball end bulb, bearing inner ring contacts for the face of running-fit with upper end, ball end bulb, changing that original rolling body contacts with point between bulb is the face contact, simultaneously, under ball end stage clip effect up and down, not only make the stressed balanced and reasonable more of ball end, ball end end globoid center origin is on the axis of steering track rod joint all the time, difficult departing from, improved the strained condition of ball end when turning to, make rotation more flexible, more steady when vehicle ' and operation, reduce service expenditure and operation cost, prolonged service life greatly.
Description of drawings
Fig. 1 is an integral structure scheme drawing of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is the improvement of making on existing four-wheel agricultural vehicle steering track rod joint design basis, this Agricultural automotive vehicle steering track rod connector assembly comprises the ball end 4 that is assemblied in the steering track rod joint body 1, lower end, described ball end 4 bulb is equipped with the bowl bodies 3 with ball end 4 bulb form fit, and this bowl bodies 3 is that face contacts with lower end, ball end 4 bulb; Upper end, ball end 4 bulbs assembling deep groove ball bearing 5, bearing 5 inner ring internal face shapes and upper end, ball end 4 bulbs coupling, promptly the internal face of bearing 5 inner ring the latter halfs is a curved surface, this curved surface is connected with the contact of ball head plane and the running-fit of ball end 4; Suit seals felt pan 6 and seals compressing tablet 7 to block dust or foreign matter successively on ball end 4; Pin shaft hole bottom assembling adjustment nut 9, ball end 4 tops are equipped with a tower shape stage clip 8,3 equipped tower shape stage clips 2 of adjustment nut 9 and bowl bodies, because the common contention effect of tower shape stage clip 2 and tower shape stage clip 8, not only ball end 4 rotates flexibly, can make simultaneously between 3 of ball end 4 and bowl bodies and ball end 4 and bearing 5 inner ring internal faces contact tightr, more steady when vehicle ' and operation.
Claims (2)
