Abstract
The utility model relates to a heavy-duty fork-lift steering axle with an improved locking structure for a steering knuckle and a steering king pin. The left and the right ends of a steering axle body are connected with the steering knuckle through the steering king pin; the steering knuckle comprises a steering knuckle body and a steering knuckle arm; a king pin hole is formed in the steering knuckle body; the steering king pin is arranged in the king pin hole in the steering knuckle body; a threaded hole is formed in the radial direction of the steering knuckle body in a position corresponding to the radial direction of the steering king pin; a mounting plane is arranged in the orifice of the threaded hole; a tapered blind hole is formed in the radial direction of the steering king pin on the side corresponding the threaded hole of the steering knuckle body; the steering knuckle body and the steering king pin are locked through a set screw with an internal hexagonal pyramid end; and the internal hexagonal pyramid end of the set screw is arranged in the tapered blind hole of the steering king pin in a matched manner. The steering axle has the advantages that the processing operation for the steering knuckle and the steering king pin is greatly reduced; the processing difficulty is greatly reduced; the set screw is a fastener meeting national standards, so as to be purchased conveniently without special production; and the locking structure is simple and convenient to mount.
Description
Technical field
The utility model belongs to the forklift steering bridge technical field, is specifically related to heavy forklift steering bridge.
Background technology
Steering swivel need be locked at co-operation through certain mechanism with steering yoke bolt on the heavy forklift steering bridge; Existing steering swivel and steering yoke bolt catch gear are: directly upwards process through hole at steering swivel and steering yoke bolt respectively; The purpose made holding pin penetrates from a side of knuckle bores, passes the through hole of steering yoke bolt, passes from the opposite side of knuckle bores; It penetrates end and utilizes self diameter to fix greater than knuckle bores; Traversing through end is used nut locking, in order to guarantee the area of contact of holding pin and steering swivel, need process plane (it was the face of cylinder originally that steering swivel needs the machining hole place) in the both sides of knuckle bores.There is following shortcoming in this kind catch gear: 1, steering swivel and steering yoke bolt all need be processed through hole, and difficulty of processing is big, and processing capacity is big; 2, holding pin is complex-shaped, needs special; 3, steering yoke bolt need be processed through hole, and steering yoke bolt intensity is had very big influence, reduces the load-carrying capacity of steering yoke bolt.
Summary of the invention
In order to reduce the processing capacity of mechanism element, avoid the intensity of steering yoke bolt is caused big influence; Through structural development, the utility model provides a kind of heavy forklift steering bridge that has improved steering swivel and steering yoke bolt locking mechanism.
Concrete improvement technical scheme is following:
The heavy forklift steering bridge that has improved steering swivel and steering yoke bolt locking mechanism comprises and turns to pontic; Turn to the right ends of pontic connecting steering swivel through steering yoke bolt respectively; Steering swivel comprises knuckle body and track arm; Offer kingpin bore on the knuckle body, steering yoke bolt is positioned at the kingpin bore on the knuckle body;
Upwards offer tapped bore with footpath on the radially cooresponding knuckle body of steering yoke bolt, the aperture of tapped bore is provided with a mounting plane; Radially offer tapered blind hole with cooresponding steering yoke bolt one side of the tapped bore on the knuckle body; Through the locking of interior hexagonal awl end holding screw, the awl end of interior hexagonal awl end holding screw cooperates the tapered blind hole that is positioned at steering yoke bolt between knuckle body and the steering yoke bolt.
The utility model is compared with prior art products and is had the advantage of following aspect:
1, the processing capacity of steering swivel of the utility model and steering yoke bolt reduces greatly, has greatly reduced difficulty of processing;
2, the utility model used in hexagonal awl end holding screw be the national standard fastener, do not need specially, buying is convenient;
3, the utility model is simple in structure, and is easy for installation.
Description of drawings

Fig. 2 is steering swivel and steering yoke bolt fitted shaft mapping.
Fig. 3 is the steering swivel scheme drawing.
Fig. 4 is the steering yoke bolt scheme drawing.
Fig. 5 is that steering swivel and steering yoke bolt cooperate cutaway view.
Sequence number among the last figure: turn to pontic 1, steering swivel 2, tapped bore 2.1, mounting plane 2.2, interior hexagonal awl end holding screw 3, steering yoke bolt 4, tapered blind hole 4.1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done explanation further through embodiment.
Embodiment:
Referring to Fig. 1; The heavy forklift steering bridge that has improved steering swivel and steering yoke bolt locking mechanism comprises and turns to pontic 1; Turn to the right ends of pontic 1 connecting steering swivel 2 through steering yoke bolt 4 respectively, steering swivel 2 comprises knuckle body and track arm, offers kingpin bore on the knuckle body; Steering yoke bolt 4 is positioned at the kingpin bore on the knuckle body, sees Fig. 2.
Referring to Fig. 3 and Fig. 4, upwards offer tapped bore 2.1 with footpath on the radially cooresponding knuckle body of steering yoke bolt 4, the aperture of tapped bore 2.1 is provided with a mounting plane 2.2; Radially offer tapered blind hole 4.1 with tapped bore 2.1 cooresponding steering yoke bolt 4 one sides on the knuckle body; Referring to Fig. 5, through 3 lockings of interior hexagonal awl end holding screw, the awl end of interior hexagonal awl end holding screw 3 cooperates the tapered blind hole 4.1 that is positioned at steering yoke bolt 4, thereby realizes the locking of steering swivel 2 and steering yoke bolt 4 between knuckle body and the steering yoke bolt 4.
Claims (1)
1. improved the heavy forklift steering bridge of steering swivel and steering yoke bolt locking mechanism; Comprise and turn to pontic; Turn to the right ends of pontic connecting steering swivel through steering yoke bolt respectively, steering swivel comprises knuckle body and track arm, offers kingpin bore on the knuckle body; Steering yoke bolt is positioned at the kingpin bore on the knuckle body, it is characterized in that:
Upwards offer tapped bore with footpath on the radially cooresponding knuckle body of steering yoke bolt, the aperture of tapped bore is provided with a mounting plane; Radially offer tapered blind hole with cooresponding steering yoke bolt one side of the tapped bore on the knuckle body; Through the locking of interior hexagonal awl end holding screw, the awl end of interior hexagonal awl end holding screw cooperates the tapered blind hole that is positioned at steering yoke bolt between knuckle body and the steering yoke bolt.
