Abstract

The invention discloses a full-hydraulic steering system of a double front-axle passenger step. The front part of a frame is provided with a first steering axle and a second steering axle, and a full-hydraulic steering follower and a middle swing arm are arranged between the first steering axle and the second steering axle, wherein the full-hydraulic steering follower is arranged on the external side of a longitudinal beam of the frame. The front end of a first pull rod is hinged with a steering knuckle arm bulb of the first steering axle, and the rear end of the first pull rod is hinged with the lower part of the middle swing arm. The front end of the second pull rod is hinged with the lower part of the middle swing arm, and the rear end of the second pull rod is hinged with a steering knuckle arm bulb of the second steering axle. The full-hydraulic steering system of the double front-axle passenger step adjusts the original single front-axle steering system into the existing double front-axle steering system, so that the defect that the load of the original single front-axle steering system is large can be favorably overcome. Moreover, the full-hydraulic steering system of the double front-axle passenger step adopts the middle swing arm to drive the steering knuckle arms of the first steering axle 2 and the second steering axle 3 to rotate synchronously. The full-hydraulic steering system of the double front-axle passenger step has the advantages of simple structure and easiness in construction.

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] The 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 front axle I-beam, and the left and right steering knuckles are controlled by this oil cylinder. The arm turns. 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 existing single front axle st...
