Abstract

The invention discloses a full hydraulic steering system of a passenger step with double front axles. According to the full hydraulic steering system of the passenger step with double front axles, the front part of a frame is provided with a first steering axle and a second steering axle, and the second steering axle is paralleled in front of the first steering axle; a combination joint and a middle swing arm are arranged between the first steering axle and the second steering axle, the upper end part of the middle swing arm is hinged with a pin shaft, and the pin shaft is arranged on the outer side surface of a longitudinal beam of the frame; and the combination joint is arranged on the outer side surface of the longitudinal beam of the frame and provided with an oil inlet hole, an oil return hole, a first oil outlet hole, a second oil outlet hole, a third oil outlet hole and a fourth oil outlet hole. According to the invention, an original steering system with a single front axle is adjusted into the steering system with double front axles at present, so that the defect of high load of the original steering system with the single front axle can be better overcome; and moreover, steering knuckle arms of the first steering axle and the second steering axle are driven by adopting the same middle swing arm to synchronously steer, and the full hydraulic steering system has the advantages of simple structure and easiness of application.

Description

technical field [0001] The invention relates to the field of passenger ladder vehicles, in particular to a full hydraulic steering system of a passenger ladder vehicle with double front axles. Background technique [0002] Existing passenger elevator vehicles are all single front axle passenger elevator vehicles, and its steering system is a single front axle steering system, that is, a double-piston double-acting oil cylinder is installed on the I-beam of the front steering axle, and the left and right sides are controlled by this oil cylinder. The knuckle arm realizes the steering. During use, we found that the load of the existing single front axle steering system is too large, so it is urgent to solve the above technical problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fully hydraulic steering system for passenger ladder vehicles with double front axles, so as to overcome the defect that the exist...
