[0002] like figure 2 and Figure 5 As shown, when assembling the steering axle, in the prior art, the steering knuckle 2 and the steering kingpin 3 are positioned through the fastening pin 12. One end of the fastening pin 12 passes through the side wall of the steering knuckle 2, and the fastening pin 12 The other end passes through the side wall of the steering kingpin 3 and passes through the side wall of the other side of the steering knuckle 2. In the actual processing of the above-mentioned prior art solution, the transverse through hole on the steering knuckle 2 and the transverse through hole on the steering kingpin 3 The size of the blind hole is difficult to control, its processing is difficult, the scrap rate is high, and the manufacturing cost is high, so it is necessary to improve

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 [0001] The invention relates to a structure of a forklift drive axle, in particular to a forklift drive axle with an improved connection structure between a steering knuckle and a steering kingpin. Background technique [0002] Such as figure 2 and Figure 5 As shown, when assembling the steering axle, in the prior art, the steering knuckle 2 and the steering kingpin 3 are positioned through the fastening pin 12. One end of the fastening pin 12 passes through the side wall of the steering knuckle 2, and the fastening pin 12 The other end passes through the side wall of the steering kingpin 3 and passes through the side wall of the other side of the steering knuckle 2. In the actual processing of the above-mentioned prior art solution, the transverse through hole on the steering knuckle 2 and the transverse through hole on the steering kingpin 3 The size of the blind hole is difficult to control, its processing is difficult, the scrap rate is high, and the m...
