Crawler Hydraulic Bulldozer TQ160TQ160A in the reference and absorption of foreign advanced technology, based on a self-developed hydrostatic drive track-type bulldozer. It uses the procurement of international purchasing parts, bulldozer on the performance of the engine, the main hydraulic pump, drive motor and key electrical components of the international brand-name products are used to ensure that the aircraft of superior performance, while also integrated into a number of design Innovative technology1, Main technical parametersDeutz Engine BF6M1013E (imported)Rated Power (kW) / speed (r / min) 137 / 2 300Total mass (kg) 16 500Track center distance (mm) 1 880Ground contact length (mm) 2 430Track Width (mm) 510Ground pressure (kPa) 67Blade (L × H) (mm) 3 420 × 1 150Soil depth of maximum shear blade (mm) 545Blade maximum lift height (mm) 1 095Minimum turning radius (without blade) (mm) 1 900Speed (km / h) forward two block: 0 ~ 4.5,0 ~ 10Back two block: 0 ~ 4.5,0 ~ 102, the main structure and performance characteristics2.1 set axis units frameShown in Figure 1, sets the frame with swing shaft structure, which with the balance beam is connected via a dedicated articulated mechanism to fully meet the bulldozer work in Taiwan, the swing frame required; and racks through the fixed pivot independent of each other , pivot detachable structure, most of the weight machine passed directly to the frame through the pivot, thus greatly reducing the transmission ofthe bulldozer was at work, the impact and prolong the life of the transmission system; pendulum shaft structure Province frame to the traditional structure of the ramp platform support, simplified structure, improved processing technology, reduce production cost and increase rigidity; the final drive and sets the frame separately, without dismantling the case of Taiwan, a direct repair frame Final drive, easy maintenance.2.2 Work equipment controlsWorking. device control by the pilot control system, all actions Blade: upgrade, down, left and right tilt and float, complete with a handle and manipulate very labor-saving, light sensitive, accurate and reliable. Figure 2 shows the blade control handle. At the same time, the aircraft are also used with ripper pilot hydraulic control systems.2.3 Driving and parking brake control systemHydraulic proportional control servo drive control system, the system consists of a dedicated pilot gear pump oil, the forward, backward, left turn and driver-specific in situ hydrostatic steering performance focused on a handle, while the handle is integrated tra vel speakers , speed, and reversing alarm switch block, which greatly simplifies the control system running, so the driver can concentrate on work.When the control lever is in neutral position, the pump will cut off access to the variable ratio power servo control valve oil, zero displacement hydraulic pump, hydraulic motor lock, the vehicle can not walk, so as to achieve the purpose of the safety brake. To ensure the safety of vehicles, aircraft design is still a driven gear shaft safety brake for parking (or emergency parking brake), the brake is normally closed, when the engine stalled or moving the operating handle is in neutral position, the brakes closed under spring force, to achieve braking; and when the manipulation of moving the handle, the role of the control to open the brake fluid, so that bulldozers driving. Parking brake lever by the brake control and emergency brake button control, manipulation of any of them, can achieve braking.2.4 TransmissionShown in Figure 3, TQ160A bulldozers closed double-loopdouble-pump hydraulic system, driven by the engine double variable pump, piston-type variable hydraulic motor driven, hydrostatic drive system components, and finally tracked vehicle driven by the final drive and steering. Each side of the track system by an independent hydrostatic drive, so that bulldozers can easily achieve pivot turn, greatly enhanced the mobility of the bulldozers and work suitability.Our unique control system of the engine closed-loop constant power control system, the central controller (CPU) load based on the size of bulldozers at any time suffered moderator pump swashplate angle control drive system flow to the machine to automatically according to the size of external load adjust speed, fully meet the bulldozers at work on speed and power requirements to ensure the efficiency of machine, to prevent overloading the engine and can make full use of engine power.TQ160A bulldozer driven by electric motor two-block variable motor, the whole block forward and backward are the two to meet the needs of different conditions.2.5 Intelligent alarm systemTQ160A three bulldozers with complete intelligent alarm system, through the instrument panel meters, LED, buzzer and LCD monitors to keep it informed of the vehicle running all kinds of information, such as: engine temperature, oil pressure, hydraulic oil temperature, working hours, engine speed and battery charge and discharge; the sensors to collect information processed by the CPU through the liquid crystal display to determine a text or voice expressed in the form, such as thework of the solenoid valve opening, engine speed and the machine appears failure, etc.; The display can also work to select the operating mode of the engine.2.6 MaintenanceAs a result of hydrostatic transmission system, eliminating the torque converter drive bulldozers, power transmission, a central transmission, steering clutches and steering brakes and other components, greatly simplifying the whole structure, so that maintenance of the transmission system is convenient.In order to facilitate the hydraulic system pressure measurement, to help repair and maintenance, the aircraft pressure measurement using a centralized approach, all the measurement points are located in the left cabinets, open the box lid can see, very convenient. The aircraft left engine cover, left box spring cover support oil and gas are used, open save time and effort.2.7Modeling and machine vision drivers.Whole shape of beautiful and unique machine, the cab structure with six sides, so as to increase the door width of the cab, front blade to enhance the hydraulic cylinder, compared with the traditional style, greatly improved vision.2.8 configurationROPS / FOPS cab, straight tilting blade and the machine after the traction frame is a standard configuration. At the same time, users can use optional different angle blade, ripper, and heating and air conditioning.ＴＱ16０履带式全液压推土机ＴＱ１６０Ａ是在参考和吸收国外先进技术的基础上，自行研制开发的一种静液压驱动履带式推土机。
