Steering knuckle connection mechanism and aerial work platform using same

Abstract

The invention discloses a steering knuckle connection mechanism and an aerial work platform using the same. The steering knuckle connection mechanism comprises a sleeve (1), a chassis main structure (2) and a steering knuckle (8). The sleeve (1) is fixed to the chassis main structure (2). An upper bearing (3) and a lower bearing (4) are installed on the upper portion and the lower portion of the sleeve (1) correspondingly. A steering knuckle main hinge pin (5) on the upper portion of the steering knuckle (8) is nested in the sleeve (1) directly and is matched with the upper bearing (3) and the lower bearing (4). An abrasion-resistant pad (7) is arranged between the lower end face of the sleeve (1) and the lower end face of the steering knuckle main hinge pin (5), and thus flexible steering during traveling of a full vehicle is achieved. According to the steering knuckle connection mechanism and the aerial work platform using the same, the steering knuckle main hinge pin is directly installed in the sleeve fixed to the chassis main structure and is matched with the upper bearing and the lower bearing, the abrasion-resistant pad is used, thus an axle structure is abolished directly, stable and reliable steering operation is achieved, manufacturing is simple and convenient, and assembly is simple.

Description

technical field [0001] The invention relates to a steering knuckle connection mechanism and an aerial work platform using the mechanism. Background technique [0002] The scissor-type aerial work platform is a kind of aerial work equipment that allows indoor operations, with a self-propelled chassis, a scissor arm and a working platform. Indoor work has the characteristics of crowded working environment and narrow working space, which requires the steering mechanism of the vehicle to be compact in size, frequent steering, and large steering angle. practical use is very important. See the schematic diagram of the vehicle figure 1 , the chassis schematic diagram see figure 2 . [0003] At present, the most up-and-down articulated knuckle connection mechanism on the market; image 3 shown. This mechanism requires a separate axle structure to connect with it, which requires a large layout space and complicated assembly. Compared with the scissor-type aerial work platform,...

AI Technical Summary

Problems solved by technology

This mechanism requires a separate axle structure to connect with it, which requires a large layout space and complicated assembly. Compared with the scissor-type aerial work platform, the layout is difficult, and the manufacturing and production costs are high, which cannot meet the requirements of the scissor-type aerial work platform. The steering mechanism of the work platform is small and convenient, and the economy and manufacturing process are not good.
