Crank arm type aerial work platform vehicle chassis axle structure

Abstract

The invention discloses a crank arm type aerial work platform vehicle chassis axle structure comprising a main frame. A front axle is connected in front of the main frame; a rear axle is connected behind the main frame, the middles of the front axle and the rear axle are transversely hinged to the front end and the rear end of the main frame respectively, and the two sides of the hinged position of the front axle and the rear axle are vertically connected through a front supporting oil cylinder and a rear supporting oil cylinder respectively; steering knuckles are hinged to the two ends of thefront axle and the two ends of the rear axle respectively; and wheels are installed outside the steering knuckles. According to the crank arm type aerial work platform vehicle chassis axle structure,the front axle and the main vehicle frame are supported and connected through the supporting oil cylinders, and the supporting oil cylinders have the oil mixing swing functions so that the trafficability of an aerial work platform vehicle can be improved; besides, the front steering oil cylinder and the rear steering oil cylinder are jointly controlled through two sets of electromagnetic reversing valves, the same-direction deflection mode or the reverse-direction deflection mode of the front wheels and the rear wheels is achieved, oblique movement of the aerial work platform car is achieved,the turning radius is reduced, and the aerial work platform car can work within a small range.

Description

technical field [0001] The invention relates to the field of aerial work platform vehicles, and more specifically relates to a chassis and axle structure of an articulating arm type aerial work platform vehicle. 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. [0003] Most of the existing aerial work platform vehicles are hard-connected between the axle and the frame, so that the platform vehicle has poor passability when driving on uneven roads or roads with obstacles, which may cause one wheel to hang in the air. , affecting safety; in additi...

Problems solved by technology

[0003] Most of the existing aerial work platform vehicles are hard-connected between the axle and the frame, so that the platform vehicle has poor passability when driving on uneven roads or roads with obstacles, which may cause one wheel to hang in the air. , affecting safety; in addition, in the working environment with small space, the turning radius of the front wheel steering of the existing aerial work platform vehicle is relatively large, which has great limitations
