The invention provides a small four-wheel steering road sweeper steering device which comprises a steering wheel, a power transmission mechanism and a power execution mechanism, the power execution mechanism comprises a steering machine, a front steering oil cylinder and a rear steering oil cylinder, and the steering wheel is connected to the steering machine through the power transmission mechanism; the steering machine and the front steering oil cylinder are connected through a rigid structural member to form linkage, and the front steering oil cylinder and the rear steering oil cylinder are connected through a hydraulic pipeline to form linkage; the steering machine is connected with front left and right wheel steering knuckles of the road sweeper, the rear steering oil cylinder is connected with rear left and right wheel steering knuckles of the road sweeper, and when the steering wheel acts through linkage of the steering machine, the front steering oil cylinder and the rear steering oil cylinder, the rotating direction of the front left and right wheels of the road sweeper is opposite to the rotating direction of the rear left and right wheels of the road sweeper. According to the device, four-wheel steering of the road sweeper can be achieved, the turning radius of the device is smaller than that of a two-wheel road sweeper, small-radius turning can be achieved in a narrow working space, and steering maneuverability is improved.
本发明提供一种小型四轮转向扫路机转向装置,包括方向盘、动力传动机构以及动力执行机构,动力执行机构包括转向机、前置转向油缸以及后置转向油缸,方向盘通过动力传动机构连接至转向机,转向机与前置转向油缸之间通过刚性结构件连接形成联动,前置转向油缸与后置转向油缸之间通过液压管路连接形成联动;转向机连接扫路机的前左右轮转向节,后置转向油缸连接扫路机的后左右轮转向节,转向机、前置转向油缸、后置转向油缸的联动使得方向盘动作时,扫路机的前左右轮转动方向与后左右轮转动方向相反。本装置可以实现扫路机的四轮转向,比两轮扫路机的转弯半径小,可以在狭小工作空间中,实现小半径调转,提高了转向的机动性。
