全地面起重机是工程机械领域复杂度最大、技术含量最高的产品门类之一,是风电、高铁、核电、石化等重大工程施工的必需装备,在经济建设中发挥着不可替代的作用。全地面起重机轴数多、车身长,采用传统机械连杆转向机构,无法解决多轴车辆高速行驶转向稳定性差、低速行驶转向灵活性差的难题,为此国内外全地面起重机普遍采用多轴多模式电液转向。多轴多模式电液转向不仅简化了多轴车辆转向杆系设计,而且很好地解决了轮胎实际转角与理论转角偏差大导致的轮胎异常磨损问题。同时它具有多种转向模式,大大提高了车辆行驶的机动灵活性。本文以某六轴全地面起重机多轴多模式电液转向系
The all-terrain crane is one of the most complex and highly technical product categories in the field of construction machinery. It is a necessary equipment for the construction of major projects such as wind power, high-speed rail, nuclear power, and petrochemicals, and plays an irreplaceable role in economic construction. All-terrain cranes have many shafts and long bodies. The use of traditional mechanical linkage steering mechanisms cannot solve the problems of poor steering stability at high speeds and poor flexibility at low speeds for multi-axle vehicles. For this reason, all-terrain cranes at home and abroad generally adopt multi-axis and multi-mode. Electrohydraulic steering. The multi-axis multi-mode electro-hydraulic steering not only simplifies the design of the multi-axle vehicle steering linkage system, but also solves the tire abnormal wear problem caused by the large deviation between the actual tire rotation angle and the theoretical rotation angle. At the same time it has a variety of steering modes, which greatly improves the mobility of the vehicle. This paper uses a six-axis all-terrain crane multi-axis multi-mode electro-hydraulic steering system.
