1、 Purpose and characteristics

我公司研制的井下装载机，结构合理，操作维护方便，适用于水利工程、市政建设、煤、砂石料厂以及车站、码头、仓库等工矿企业中铲装松散物料，并可进行短距离运输。

The underground loader developed by our company has reasonable structure and convenient operation and maintenance. It is suitable for shoveling and loading loose materials in hydraulic engineering, municipal construction, coal, gravel plants, stations, wharfs, warehouses and other industrial and mining enterprises, and can be transported over a short distance.

本机传动系统一种是机械式传动、一种是液力机械传动。采用液力机械传动装置，该装置是由液力变矩器和动力换挡变速箱组成，液力变矩器与发动机合理匹配充分利用发动机功率，加大发动机输入扭矩力使整机具有较大的牵引力。

The transmission system of the machine is mechanical transmission and hydraulic mechanical transmission. The hydraulic mechanical transmission device is adopted, which is composed of hydraulic torque converter and power shift gearbox. The hydraulic torque converter is reasonably matched with the engine, makes full use of the engine power, increases the input torque force of the engine, and makes the whole machine have greater traction.

带液力变矩器的传动具有以下优点：一使用装载机具有自动适应性。当外载荷突然加大时，能自动加大牵引力以克服加大的外载荷。同时，车辆自动降低速度，避免外载荷的继续加大而熄火。反之，当外载荷减小时，车辆又自动的减少牵引力，提供车辆的速度。二由于液力传动的工作介质是液体，能吸收来自发动机和载荷的振动与冲击。从而保护了发动机和传动装置，提高了装载机的寿命。三装有液力变矩器的传动系统可以使农用装载机以任意小的速度行驶，从而提高了车辆的通过性。四装载机装了液力变矩器，可以平稳起步并在较大的速度范围内实现无级变速，可以吸收震动和冲击，提高了车辆的舒适性。五简化了装载机的操作，减少了司机的劳动强度。动力换挡变速箱是定轴式的，结构简单紧凑，尺寸小，维修方便。另外换挡轻便，平稳。它与液力变矩器组装后，传动系统有较大的传动范围和较理想的效率。

The transmission with hydraulic torque converter has the following advantages: first, the loader has automatic adaptability. When the external load suddenly increases, it can automatically increase the traction force to overcome the increased external load. At the same time, the vehicle automatically reduces the speed to avoid stalling due to the continuous increase of external load. On the contrary, when the external load is reduced, the vehicle will automatically reduce the traction and provide the vehicle speed. Second, because the working medium of hydraulic transmission is liquid, it can absorb the vibration and impact from the engine and load. Thus, the engine and transmission device are protected and the service life of the loader is improved. The transmission system equipped with hydraulic torque converter can make the agricultural loader run at any small speed, so as to improve the trafficability of the vehicle. The fourth loader is equipped with hydraulic torque converter, which can start smoothly and realize stepless speed change in a large speed range, absorb vibration and impact, and improve the comfort of the vehicle. Fifth, the operation of the loader is simplified and the labor intensity of the driver is reduced. The power shift gearbox is a fixed shaft type, with simple and compact structure, small size and convenient maintenance. In addition, shifting is light and stable. After it is assembled with the hydraulic torque converter, the transmission system has a large transmission range and ideal efficiency.

整机是铰接车架连接，采用全液压负荷传感转向器及阀组成的全液压负荷转向系统，其特点是转向轻便、灵活可靠。无论转向负载大小，方向盘转速高低，均能保持平滑转向。而且整个工作过程使油泵输出的流量得到充分的利用，避免了功率损失，提高了系统效率。

The whole machine is connected by articulated frame, and the full hydraulic load steering system composed of full hydraulic load sensing steering gear and valve is characterized by light, flexible and reliable steering. Smooth steering can be maintained regardless of steering load and steering wheel speed. Moreover, the whole working process makes full use of the output flow of the oil pump, avoids power loss and improves the system efficiency.

采用宽基低压轮胎-四轮驱动，因此，牵引力大。另外，由于采用宽基低压轮胎，提高了在沼泽、松软地面的通过性。

Wide base low-pressure tire - four-wheel drive is adopted, so the traction is large. In addition, due to the use of wide base low-pressure tire, the trafficability in swamp and soft ground is improved.
