Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and examples, and the contents of the examples are not intended to limit the protection scope of the present invention.

[0015] figure 1 A schematic structural view of the four-wheel four-drive and four-steering system of the forklift according to the present invention is shown. Such as figure 1 As shown, the four-wheel four-drive and four-steering system of the forklift of the present invention includes a front drive steering axle 1 and a rear drive steering axle 2 . Different from the drive and steering system of the existing forklift that adopts front drive and rear steering, in the present invention, both the front drive steering axle 1 and the rear drive steering axle 2 can simultaneously realize the driving and steering functions.

[0016] Both ends of the front drive steering axle 1 and the rear drive steering axle 2 are equipped with wheels 4 . Wherein, a hydr...

Abstract

The invention relates to a four-wheel, four-drive and four-steering system of a forklift, comprising a front drive steering axle and a rear drive steering axle, wheels are installed at both ends of the front drive steering axle and the rear drive steering axle, and the front drive steering axle and the rear drive steering axle There is a hydraulic torque converter between the bridges. The hydraulic torque converter is connected to the front drive steering axle through the front transmission shaft and connected to the rear drive steering axle through the rear drive shaft. The front drive steering axle is equipped with a front steering cylinder. The two cylinder rods of the steering cylinder are respectively connected with the front steering shaft, the rear steering axle is equipped with a rear steering cylinder, the two cylinder rods of the rear steering cylinder are respectively connected with the rear steering shaft, and one of the front steering shafts is connected with one of the rear steering shafts. The shafts are connected by a synchronous steering connection shaft. This system can realize the four-wheel four-drive and four-steering of the forklift, thereby improving its climbing ability and driving more stable.

Description

technical field [0001] The invention belongs to the technical field of forklifts for carrying goods, and relates to a driving and steering system of a forklift, in particular to a four-wheel, four-drive and four-steering system of a forklift. Background technique [0002] Forklifts refer to various wheeled handling vehicles for loading and unloading, stacking, short-distance transportation, and heavy handling of palletized goods. Most of the existing forklifts adopt rear steering and front drive structure. The main problems of this rear steering and front drive structure are: 1. poor climbing ability; 2. not suitable for potholes and muddy roads. [0003] In addition, although the existing forklifts are four-wheel drive off-road, they are not four-steering, and the front and rear car bodies are fixed by pins. Stable, prone to problems such as rollover and cargo slipping, unstable direction operation, and off-road performance cannot be achieved. [0004] In view of the abo...
