Abstract

The invention discloses a traveling chassis with a high-stability traveling steering function. The traveling chassis is characterized by comprising a chassis, a traveling device and a support leg structure, wherein the traveling device comprises a left steering wheel, a right steering wheel, a left wheel frame, a right wheel frame, a linkage frame, a steering cylinder and steering bent plates, and the left steering wheel and the right steering wheel are rotationally mounted on the left wheel frame and the right wheel frame respectively and are driven respectively through a left driving motor which is fixedly arranged on the left wheel frame and a right driving motor which is fixedly arranged on the right wheel frame. According to the traveling chassis, the steering cylinder is a double-rod hydraulic cylinder, so that the linkage structure is simplified, and the stability and synchronism of a steering process are improved; depressions are formed in the steering bent plates, so that the steering bent plates can be closer to a wheel frame axle, thus, the angle limit of steering can be increased, and use performance is enhanced.

Description

technical field [0001] The invention relates to a driving chassis with a high-stability driving steering function. Background technique [0002] Aerial work platform is a product that serves mobile high-altitude operations such as aerial work, equipment installation, and maintenance in various industries. The related products of aerial work platforms mainly include: scissor-type aerial work platforms, vehicle-mounted aerial work platforms, articulating-arm aerial work platforms, self-propelled aerial work platforms, aluminum alloy aerial work platforms, and cylinder-type aerial work platforms. The following problems exist in the driving chassis of the existing aerial work platform: during the operation of the aerial work platform, the platform operation requires high mobile flexibility, the steering structure of the existing driving wheel has poor stability and synchronization during the steering process, and The rotation angle is limited, which affects the user experience....
