某些工程机械工作装置布置在前后轮之间,如中置式稳定土拌和机,此类机械机身较长,作业时转向频繁,要求转向半径小。本文提出了用全液压转向器,实现前后轮同时偏转的转向方式及全液压转向系统,以减小此类工程机械的转向半径,并可实现机械偏行,提高作业时的机动性。 Some of the construction machinery working devices are arranged between the front and rear wheels, such as medium-type stabilized soil mixing machines. Such machines have longer fuselage, turn frequently during operation and require a smaller turning radius. In this paper, a steering system and full hydraulic steering system with full hydraulic steering gear to achieve simultaneous deflection of the front and rear wheels are proposed to reduce the turning radius of such engineering machinery, and to realize mechanical deviation and improve maneuverability during operation.
