冷再生机是一种多功能施工机械,主要用于旧沥青路面的升级改造,即基层冷再生;还可用于公路、城乡道路、机场、码头和停车场等工程的基层、底基层稳定土现场就地拌合作业。冷再生机的液压系统由5部分组成:行走液压驱动系统、工作装置液压驱动系统、液压喷洒系统、液压转向系统和辅助液压系统,
Cold recycling machine is a multifunctional construction machinery mainly used for upgrading and renovating old asphalt pavement, that is, cold recycling of the base layer; It can also be used for on-site mixing of stabilized soil at the base and subbase levels in projects such as highways, urban-rural roads, airports, docks, and parking lots. The hydraulic system of the cold regeneration machine consists of five parts: walking hydraulic drive system, working device hydraulic drive system, hydraulic spraying system, hydraulic steering system, and auxiliary hydraulic system,
1行走液压驱动系统
1. Traveling hydraulic drive system
行走液压系统主要是为整机的行走提供动力,调整行驶速度,实现整车前进和后退。该系统由SAUER90L75泵、SAUER90M55 前桥马达和 SAUER51D110-1两点控制的后桥变量马达组成一个闭式静液压驱动系统,通过90L75泵中斜盘倾角的变化改变泵流量大小,从而实现调速。
The walking hydraulic system mainly provides power for the entire machine's walking, adjusts the driving speed, and realizes the forward and backward movement of the entire vehicle. The system consists of a SAUER90L75 pump, a SAUER90M55 front axle motor, and a SAUER51D110-1 two point controlled rear axle variable motor, forming a closed hydrostatic drive system. By changing the inclination angle of the swashplate in the 90L75 pump, the pump flow rate is changed to achieve speed regulation.

SAUER90L75泵的排量由驾驶室内操作台右侧的软轴控制器手柄控制,停车时手柄处于中位:向前搬手柄,软轴钢丝带动90L75泵控制手柄转动,使泵的斜盘倾角发生变化而改变泵的排量,使驱动前桥的定量马达和驱动后桥的变量马达改变其输出转速,车辆前行;当操纵手柄搬到相反位置时则90L75泵的进出
The displacement of the SAUER90L75 pump is controlled by the soft shaft controller handle on the right side of the operator's console in the driver's cab. When parking, the handle is in the middle position: move the handle forward, and the soft shaft steel wire drives the 90L75 pump control handle to rotate, causing a change in the inclination angle of the pump's swashplate and changing the pump displacement. This causes the quantitative motor driving the front axle and the variable motor driving the rear axle to change their output speed, causing the vehicle to move forward; When the joystick is moved to the opposite position, the inlet and outlet of the 90L75 pump
油口交换,90M55马达和51D110-1变量马达反向转动,车辆倒行。
Oil port exchange, 90M55 motor and 51D110-1 variable motor rotate in reverse, causing the vehicle to reverse.
在该系统的闭式回路中设计了回路冲洗阀,用于将系统的热油排出起到冷却作用,同时冲去回路中污物。其管路由马达上部壳体泄油口接到泵下部的壳体泄油口,然后从泵上部泄油口到集流块。
A circuit flushing valve has been designed in the closed circuit of the system, which is used to discharge the hot oil from the system for cooling purposes and flush out the dirt in the circuit. The pipe is routed from the upper housing drain port of the motor to the lower housing drain port of the pump, and then from the upper housing drain port of the pump to the manifold block.
2工作装置液压驱动系统
2 Working device hydraulic drive system
工作装置液压系统为转子提供回转运动的动力,并依不同工况适当改变其转速,它由两个SAUER90L130泵串接和两个SAUER90M100马达组成一个闭式静液压驱动系统。两个90L130泵的高压油分成两路,分别驱动铣拌转子左右两侧的90M100马达,两个马达分别安装在铣拌转子两侧的行星式减速机上,减速机输出动力驱动铣拌转子。两个90L130泵A、B口分别用两根高压胶管连接起来使两路油液的能动态互补,在本系统的闭式回路中设计了回路冲洗阀。
The hydraulic system of the working device provides power for the rotary motion of the rotor, and changes its speed appropriately according to different working conditions. It consists of two SAUER90L130 pumps connected in series and two SAUER90M100 motors to form a closed hydrostatic drive system. The high-pressure oil of two 90L130 pumps is divided into two paths, which drive the 90M100 motors on the left and right sides of the milling and mixing rotor. The two motors are installed on the planetary reducers on both sides of the milling and mixing rotor, and the reducer outputs power to drive the milling and mixing rotor. Two 90L130 pumps, Port A and Port B, are connected with two high-pressure hoses to dynamically complement the energy of the two oil circuits. A circuit flushing valve is designed in the closed circuit of this system.
3转向液压系统
3 Steering hydraulic system
冷再生机采用前后车架铰接相对偏转实现整机转向,该转向系统的特点是操纵灵活轻便、工作可靠、结构紧凑布置合理、维修保养方便。该系统由SNP3/38SSC07齿轮泵、单路稳定分流阀、液压转向器和转向油缸等液压元件组成。
The cold regeneration machine uses front and rear frame hinge relative deflection to achieve overall steering. The characteristics of this steering system are flexible and lightweight operation, reliable operation, compact structure and reasonable layout, and convenient maintenance. The system consists of hydraulic components such as SNP3/38SSC07 gear pump, single stable diverter valve, hydraulic steering gear, and steering cylinder.
