The invention belongs to the technical field of industrial vehicles and relates to a steering axle and a forklift. The steering axle includes an axle housing, a kingpin, a steering knuckle, a first conical bearing and a second conical bearing, the rotating kingpin is fixedly connected to the axle housing, the steering knuckle is provided with a pin hole, and the pin The upper end of the hole is provided with a first bearing seat, the lower end of the pin hole is provided with a second bearing seat, the first tapered bearing is fixed on the first bearing seat, and the second tapered bearing is fixed on the first bearing seat. On the second bearing seat, the steering knuckle is rotatably connected to the main pin through the first conical bearing and the second conical bearing, a gap is formed between the inner wall of the pin hole and the outer periphery of the main pin, and the An oil channel communicating with the gap is provided on the steering knuckle, and lubricating oil can be delivered to the first tapered bearing and the second tapered bearing through the oil channel and the gap. The steering axle can prolong the service life of the steering axle and reduce the failure rate of the forklift.
Description
technical field [0001] The invention belongs to the technical field of industrial vehicles, in particular to a steering axle and a forklift. Background technique [0002] The existing steering axle is generally a horizontal oil cylinder type steering axle. The two ends of the penetrating piston rod of the horizontal steering oil cylinder push the left steering knuckle and the right steering knuckle to swing through the connecting rod, so that the left steering wheel and the right steering wheel can be turned to the kingpin. Deflection for the center of the circle, so as to realize the steering of the forklift. [0003] like figure 1 and figure 2 As shown, the steering axle of a commonly used forklift at present includes a bearing housing 1a, a steering knuckle 2a, a kingpin 3a and a rotation angle sensor 4a. Among them, three holes for installing the rotation angle sensor are provided on the bearing seat 1a, and the rotation angle sensor 4a is fixedly installed on the be...
