Yishan 160HP swamp hydraulic track type crawler dozer in 2010
Product features
The low specific pressure traveling system adopts a trolley frame with 7 supporting wheels, extended crawler tracks and wide triangular arc-shaped track shoes to increase the grounding area of the bulldozer, so that the locomotive has super buoyancy, and the grounding specific pressure does not exceed 28kPa.
Steyr WD615T1-3A diesel engine with fast response performance is combined with hydraulic torque converter and power shift transmission to form a powerful transmission system, which shortens the working cycle and improves working efficiency. Liquid medium under heavy load The transmission can play the role of overload protection, so that the components of the transmission system will not be damaged and the service life will be extended.
The hydraulic torque converter enables the output torque of the bulldozer to automatically adapt to the change of the load, protects the engine from overload, and does not stop the engine when it is overloaded. The planetary powershift transmission has three forward gears and three reverse gears for quick shifting and steering.
Structural features
Main clutch:
The main clutch is wet type, multi-plate, with inertial brake, hand-operated hydraulic power assist, and has the characteristics of smooth combination, thorough separation, strong lubrication and heat dissipation capabilities, high reliability and long service life. The driven friction plate has a single steel back, both sides are sintered powder metallurgy, and there are six prefabricated warping surfaces near the circumference, which can fully ensure the separation gap between the driving and driven friction plates and the cooling and lubrication capacity, and improve the service life.
Gearbox:
The gearbox is a helical gear constant mesh type, forced lubrication, manual operation, five forward gears, and four reverse gears.
The transmission system is completed by only two pairs of gears from input to output. It has the characteristics of high transmission efficiency, simplified structure, noise reduction, reduced shock and vibration when gears mesh, long service life and convenient maintenance.
Central drive:
The central drive is a spiral bevel gear, splash lubricated. Among them, the large spiral bevel gear is placed on the left side of the output shaft of the gearbox, which greatly improves the stress condition of the output shaft of the gearbox and increases the service life of the output shaft of the gearbox.
Steering clutch:
Combined with Komatsu technology from Japan, it is completed by the prestressing of a group of large disc springs during assembly. The stress and strain capacity of disc springs are more suitable for the clutch function requirements than coil springs.
Yishan-TS160 steering clutch is equipped with a forced lubrication system. The lubricating oil can directly enter the joint surface of the friction plate. While playing the role of forced lubrication, it also plays the role of cooling and heat dissipation, thereby improving the service life and ensuring the hydraulic system. Low temperature rise.
Steering brake:
The steering brake is a wet type, with a hugging type, with pedal oil pressure assist, and with a stop brake device.
The hydraulic power-assisted operating mechanism has the characteristics of safety, reliability, flexibility and labor saving. It is less labor-intensive than a simple mechanical brake structure.
After pulling the joystick, the steering clutch can gradually transition from disengagement to braking, avoiding the abnormal wear caused by man-made braking first and then disengagement.
The combined foot brake pedal is a unique design of the Yishan series bulldozers, which can brake the steering on both sides separately, or brake the steering clutches on both sides at the same time with only one foot.
Accelerator:
The pedal accelerator device is a unique design of Yishan-T160. When the bulldozer is on a downhill slope or on a rough working surface, the pedal accelerator can be used to decelerate to prevent the impact and bumps caused by the urgent need to decelerate while driving, which enhances the safety of operation. With the help of pedal accelerator deceleration, gear shifting can also be made more convenient and quick.
Track:
Yishan-TS160 is equipped with sealed tracks. The sealed track is equipped with sealing rings at both ends of the pin sleeve to prevent the immersion of sand and other abrasives; when assembling, the joint surface of the pin and the pin sleeve is coated with grease to prevent early wear and tear, which is better than that of a track without a seal. The service life is greatly improved.
Cab:
The cab of the TS160 bulldozer is comfortable and spacious, and the large front-view window provides a wide field of view, making the working device clear at a glance. The shifting of gears is easy, and the control layout is reasonable, which is convenient for the driver to perform various operations. It can also be equipped with an anti-rollover frame according to user requirements.
