Steering system and loader
The invention relates to the technical field of steering of engineering mechanical equipment, in particular to a steering system and a loader. The steering system comprises a first steering oil cylinder, a second steering oil cylinder, a steering gear and a balancing device, the steering gear comprises an oil port P, an oil port L and an oil port R, and the oil port R is communicated with a first rodless cavity of the first steering oil cylinder and a second rod cavity of the second steering oil cylinder; the oil port L is communicated with a first rod cavity of the first steering oil cylinder and a second rodless cavity of the second steering oil cylinder; the balancing device comprises an oil port a communicated with the oil port R, an oil port b communicated with the oil port L and an oil return port; when the steering gear is switched to the cut-off position, the balancing device is suitable for communicating the first steering oil cylinder and the second steering oil cylinder, and the oil return port is suitable for communicating with the first steering oil cylinder and the second steering oil cylinder through the balancing device. According to the steering system, the pressure pulse generated after steering sudden stop is absorbed through the balancing device, and the effect of weakening left-right repeated side swaying of engineering machinery such as a loading machine during steering stop is achieved.
本发明涉及工程机械设备的转向技术领域，具体涉及一种转向系统及装载机。转向系统包括第一转向油缸、第二转向油缸、转向器和平衡装置，转向器包括P油口、L油口、R油口，R油口与第一转向油缸的第一无杆腔、第二转向油缸的第二有杆腔均连通；L油口与第一转向油缸的第一有杆腔、第二转向油缸的第二无杆腔均连通；平衡装置包括与R油口连通的a油口、与L油口连通的b油口及回油口；转向器转换至截止位时，平衡装置适于连通第一转向油缸和第二转向油缸，回油口适于通过平衡装置分别与第一转向油缸、第二转向油缸连通。本发明提供的转向系统，通过平衡装置吸收转向急停后的压力脉冲，达到减弱装载机等工程机械转向停止时的左右反复侧摆的效果。
