冷再生機(jī)主要液壓系統(tǒng)組成及作用介紹
來源：http://kqj188.com/ 日期：2023-10-24 發(fā)布人：
冷再生機(jī)是一種多功能施工機(jī)械，主要用于舊瀝青路面的升級改造，即基層冷再生;還可用于公路、城鄉(xiāng)道路、機(jī)場、碼頭和停車場等工程的基層、底基層穩(wěn)定土現(xiàn)場就地拌合作業(yè)。冷再生機(jī)的液壓系統(tǒng)由5部分組成:行走液壓驅(qū)動(dòng)系統(tǒng)、工作裝置液壓驅(qū)動(dòng)系統(tǒng)、液壓噴灑系統(tǒng)、液壓轉(zhuǎn)向系統(tǒng)和輔助液壓系統(tǒng)，
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行走液壓驅(qū)動(dòng)系統(tǒng)
1. Traveling hydraulic drive system
行走液壓系統(tǒng)主要是為整機(jī)的行走提供動(dòng)力，調(diào)整行駛速度，實(shí)現(xiàn)整車前進(jìn)和后退。該系統(tǒng)由SAUER90L75泵、SAUER90M55 前橋馬達(dá)和 SAUER51D110-1兩點(diǎn)控制的后橋變量馬達(dá)組成一個(gè)閉式靜液壓驅(qū)動(dòng)系統(tǒng)，通過90L75泵中斜盤傾角的變化改變泵流量大小，從而實(shí)現(xiàn)調(diào)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泵的排量由駕駛室內(nèi)操作臺右側(cè)的軟軸控制器手柄控制，停車時(shí)手柄處于中位:向前搬手柄，軟軸鋼絲帶動(dòng)90L75泵控制手柄轉(zhuǎn)動(dòng)，使泵的斜盤傾角發(fā)生變化而改變泵的排量，使驅(qū)動(dòng)前橋的定量馬達(dá)和驅(qū)動(dòng)后橋的變量馬達(dá)改變其輸出轉(zhuǎn)速，車輛前行;當(dāng)操縱手柄搬到相反位置時(shí)則90L75泵的進(jìn)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
油口交換，90M55馬達(dá)和51D110-1變量馬達(dá)反向轉(zhuǎn)動(dòng)，車輛倒行。
Oil port exchange, 90M55 motor and 51D110-1 variable motor rotate in reverse, causing the vehicle to reverse.
在該系統(tǒng)的閉式回路中設(shè)計(jì)了回路沖洗閥，用于將系統(tǒng)的熱油排出起到冷卻作用，同時(shí)沖去回路中污物。其管路由馬達(dá)上部殼體泄油口接到泵下部的殼體泄油口，然后從泵上部泄油口到集流塊。
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工作裝置液壓驅(qū)動(dòng)系統(tǒng)
2 Working device hydraulic drive system
工作裝置液壓系統(tǒng)為轉(zhuǎn)子提供回轉(zhuǎn)運(yùn)動(dòng)的動(dòng)力，并依不同工況適當(dāng)改變其轉(zhuǎn)速，它由兩個(gè)SAUER90L130泵串接和兩個(gè)SAUER90M100馬達(dá)組成一個(gè)閉式靜液壓驅(qū)動(dòng)系統(tǒng)。兩個(gè)90L130泵的高壓油分成兩路，分別驅(qū)動(dòng)銑拌轉(zhuǎn)子左右兩側(cè)的90M100馬達(dá)，兩個(gè)馬達(dá)分別安裝在銑拌轉(zhuǎn)子兩側(cè)的行星式減速機(jī)上，減速機(jī)輸出動(dòng)力驅(qū)動(dòng)銑拌轉(zhuǎn)子。兩個(gè)90L130泵A、B口分別用兩根高壓膠管連接起來使兩路油液的能動(dòng)態(tài)互補(bǔ)，在本系統(tǒng)的閉式回路中設(shè)計(jì)了回路沖洗閥。
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.
