Live forklift steering axle with series oil cylinders

Abstract

The invention provides a live forklift steering axle with series oil cylinders. The live forklift steering axle with the series oil cylinders comprises a left steering knuckle assembly, a right steering knuckle assembly and a steering axle body, wherein the left steering knuckle assembly is connected with a left rear wheel; the right steering knuckle assembly is connected with a right rear wheel; the steering axle body is arranged between the left steering knuckle assembly and the right steering knuckle assembly; the left steering knuckle assembly is hinged with a piston rod of a left oil cylinder; the right steering knuckle assembly is hinged with a piston rod of a right oil cylinder; cavities, without rods, of the left oil cylinders and the right oil cylinders are connected with each other through soft oil pipes; the steering axle body is divided into a left axle body and a right axle body; axle body mounting holes connected with a forklift body are formed in both the left axle body and the right axle body; a left suspension of a suspended forklift body is arranged on the left axle body; and a right suspension of the suspended forklift body is arranged on the right axle body; the left oil cylinder is fixedly arranged on the left axle body; and the right oil cylinder is fixedly arranged on the right axle body. Under a bumping working condition, the left axle body and the right axle body respectively swing so as to improve the stability of a whole vehicle; and moreover, the travels of the left oil cylinder and the right oil cylinder are consistent with each other so as to ensure that steering angles of the left wheel and the right wheel have relation to each other.

Description

technical field [0001] The invention relates to a forklift steering axle, in particular to a forklift steering axle with series oil cylinders disconnected. Background technique [0002] The forklift steering bridge plays the role of performing the steering of the forklift during the driving process of the forklift. With the development of the forklift market, high-end customers have higher and higher requirements for the safety and comfort of forklifts, which has become one of the important factors affecting the sales of forklifts. . [0003] The steering axle used by existing forklifts generally adopts an integral bridge body, and a steering oil cylinder is fixed in the middle of the bridge body, and the steering oil cylinder pushes the left and right wheels to rotate, thereby realizing steering. However, the disadvantage of the integral steering axle is that the left and right wheels cannot independently adapt to the road surface, and the adaptability to bumpy road surf...
