Abstract
The invention discloses a fork truck driving axle with an improved steering knuckle and steering king pin linkage structure and relates to a fork truck driving axle structure. The fork truck driving axle comprises a steering knuckle, a steering king pin, a fastening screw or a fastening bolt, an oil cup, a dust ring, a quill bearing, a lining, an O-shaped ring and a dust ring, wherein a reasoning ball bearing connected with the lining is arranged on the steering knuckle; the steering knuckle is provided with a transverse unilateral through hole; the steering king pin is provided with a transverse unilateral blind hole coaxial with the transverse unilateral through hole; one end of the fastening screw or the fastening bolt is arranged in the transverse unilateral blind hole, and the other end of the fastening screw or the fastening bolt passes through the transverse unilateral through hole; the axis of the transverse unilateral through hole is vertically intersected with that of the steering king pin. The fastening screw is used for replacing an existing holding pin, a square groove formed in the steering king pin in the prior art is improved as the transverse unilateral blind hole which is conical or round, and transverse bilateral through holes in two sides of the steering knuckle are improved as the transverse unilateral through hole.
Description
Technical field
The present invention relates to a kind of structure of driving axle of forklift, specifically a kind of driving axle of forklift improving steering swivel and steering yoke bolt connection structure.
Background technology
As shown in Figure 2 and Figure 5, when assembling steeraxle, prior art is positioned by holding pin 12 pairs of steering swivels 2 and steering yoke bolt 3, holding pin 12 one end passes from steering swivel 2 side sidewall, holding pin 12 other end passes steering yoke bolt 3 sidewall and passes from steering swivel 2 opposite side sidewall, above-mentioned prior art adds man-hour actual, the size of the horizontal blind hole on the cross through hole on steering swivel 2 and steering yoke bolt 3 is difficult to control, its difficulty of processing is large, reject rate is high, manufacturing cost is comparatively large, is therefore necessary to improve.
Summary of the invention
The object of the invention is the weak point in order to overcome background technology, and a kind of steeraxle steering swivel is provided.
To achieve these goals, technical scheme of the present invention is: the driving axle of forklift improving steering swivel and steering yoke bolt connection structure, comprise the steering swivel with vertical through holes, be installed on the steering yoke bolt of described vertical through holes inside, it is characterized in that: also comprise tightening screw or binding bolt, all lubricating cup is installed in the middle part of described steering yoke bolt upper center and steering yoke bolt lower end, successively dust ring is installed from top to bottom between steering yoke bolt upper end outer wall and described vertical through holes inwall, quill bearing and lining, steering swivel is provided with the reasoning ball-bearing casing be connected with described lining, between steering yoke bolt lower end outer wall and described through-hole wall, O type circle is installed successively from top to bottom, quill bearing and dust ring, described steering swivel is provided with laterally one-sided through hole, steering yoke bolt is provided with the transverse direction one-sided blind hole coaxial with the one-sided through hole of described transverse direction, tightening screw or binding bolt one end are located in horizontal one-sided blind hole, tightening screw or the binding bolt other end pass from the one-sided through hole of described transverse direction, the laterally axis of one-sided through hole and the intersect vertical axis of steering yoke bolt.
The present invention replaces existing holding pin with tightening screw, the square groove be located on steering yoke bolt (prior art) is improved to laterally one-sided blind hole (coniform hole or circular port), and the horizontal bilateral through hole be located on steering swivel both sides is improved to laterally one-sided through hole.The present invention simultaneously has also carried out suitable improvement to the oil enveloping structure between steering swivel and steering yoke bolt, makes oil sealing better effects if of the present invention.Compared with prior art, its cost is lower in last the present invention, and average every platform can save manufacturing cost 12.75 yuan, by annual output 20000 calculating, and annual saving 25.5 ten thousand yuan.
