Hydraulic system of the bulldozer T-170, 130

______________________________________________________________________________________________

The separate-aggregate hydraulic system of the T-170/130 bulldozer is used to control mounted, semi-mounted and trailed implements operating in combination with a tractor. Mounted systems are used to attach mounted and semi-mounted implements to the tractor. For the tractor (bulldozer) T-170, two types of mounted systems are provided, front and rear. Universal separate-aggregate hydraulic and hinged systems consist of a drive with a hydraulic pump, a P160 hydraulic distributor, two hydraulic tanks interconnected by turbo lines. The hydraulic pump through the high pressure hydraulic line supplies the working fluid from the hydraulic tanks to the hydraulic distributor and from it to the hydraulic cylinders. The pump drive is mounted in the casing of the diesel distribution gears. The drive gear is in constant mesh with the large intermediate gear of the diesel engine. Shaft and gear bearings are splash lubricated from the diesel lubrication system. The NSh-100A-ZL gear pump is used to periodically pump the working fluid into the cylinders of the mounted system. The pump is driven by the drive shaft. The drive shaft is connected to the pump shaft by means of a splined coupling, which serves to compensate for the radial beats of the connected shafts. Filling oil into the pump drive for lubrication of splined couplings is carried out through the breather plug to the level of the control plug. The R-160 hydraulic distributor of the T-130/170 bulldozer is designed to control the flow of working fluid in the hydraulic system and distribute it between different groups of hydraulic cylinders. The hydraulic distributor consists of distribution, bypass and safety devices. The distributing device consists of three spools, each of which, independently of the others, determines the four working positions of the corresponding group of hydraulic cylinders, for example: for hydraulic cylinders of the rear linkage mechanism - LOWER. NEUTRAL. CLIMB. FLOATING. Moreover, the positions NEUTRAL and FLOATING are fixed. At the end of the necessary stroke of the pistons of the T-170 hydraulic cylinders for LIFT and LOWER, the control lever should be released and the spool will return to the NEUTRAL position under the action of the spring. The differential type bypass device consists of a valve with a guide, a spring and a system of holes, which, when the spools are in the NEUTRAL or FLOATING positions, provide unloading of the hydraulic pump. The safety device, consisting of a ball safety valve with a spring and an adjusting screw, limits the maximum pressure in the T-170/130 hydraulic system and works in conjunction with a bypass device, ensuring that the working fluid is bypassed from the high pressure cavity to the drain when the safety valve adjustment pressure is reached. The check valve prevents the passage of the working fluid from the hydraulic cylinders through the bypass device to the drain during the switching of the spools. The R-160 hydraulic distributor is installed on the right under the cabin floor. The hydraulic tanks are connected by a power pipe, in which a filter with a bypass valve is installed. The cavities of the hydraulic tanks are connected by pipelines in the upper and lower parts and with the atmosphere through the breather valve in the right hydraulic tank. The working fluid is filled through the filler filter in the right hydraulic tank, the level is controlled by the viewing restrictive window in the right hydraulic tank. The working fluid is drained from the hydraulic tanks through the drain hole in the pipeline connecting the hydraulic tanks at the bottom. The hydraulic system filter T-130/170 sectional consists of three removable paper filter elements installed in the power pipe. For symmetrical installation of the filter, a sleeve is installed in the pipe. The drained working fluid from the P-160 hydraulic distributor enters the power pipe and overflows through the filter into the left (along the way) hydraulic tank. When the filter is clogged and the pressure rises above 0.2 MPa (2 kgf / cm2), the control lamp of the filter clogging indicator on the instrument panel goes out, the filter bypass valve is activated and the working fluid is poured into the left tank, bypassing the filter. In the absence of a clogging indicator or a malfunction, replace the filter elements after 2000 hours. On the suction line of pumps (NSh-100A-ZL, NSh-32-L) there are pipelines (siphons) with plugs. When the plugs are removed, the oil flow to the pumps is interrupted, which makes it possible to dismantle the units of the hydraulic system without draining the oil. At the end of the repair work, the plugs should be wrapped. The rear mounted system of the T-170 bulldozer is designed to attach mounted and semi-mounted machines and implements to the tractor from behind. The front mounted system is designed to attach mounted machines (implements) to the tractor from the front, a bulldozer, a puller, and others. The lifting and lowering of attachments is carried out by two hydraulic cylinders. Double-acting hydraulic cylinders are fixed on the trunnions of the hydraulic tanks. End valves are installed in the rods of the front hydraulic cylinders T-170/130, which unload the system at the end of the piston stroke. High-pressure pipelines and hoses are connected to the hydraulic distributor with fittings and slats. Sealing is achieved by installing rubber rings and cone-sphere connection. The pipelines going forward from the hydraulic distributor serve to connect the hydraulic line to the front mounted system, and those going back to the rear mounted system and the hydraulic lines of trailed implements. Attaching implements to the left section of the P-160 hydraulic distributor simultaneously forward and backward is not allowed. On tractors of the T-170M1.03-51 type, a pipeline coming from the middle section of the distributor is additionally used to connect the hydraulic skew of the blade. The pipelines going back from the right section of the hydraulic distributor serve to connect the rear attachment system, from the left and middle sections - to connect hydraulic machines and implements with the bulldozer equipment removed. Attaching implements to the left and middle sections of the P160 distributor simultaneously forward and backward is not allowed. Working chambers of hydraulic cylinders can be connected to each pair of pipelines, ensuring the operation of the implements in accordance with the plate installed in the cab. Checking and adjusting the pressure of the working fluid in the T-170/130 hydraulic system The maximum pressure in the T-170 hydraulic system should be adjusted at a working fluid temperature of 40-60 °C. Before checking the pressure, stop the diesel engine and move the levers of the P160 distributor to the FLOATING position to connect the high pressure hydraulic lines to the drain. Failure to follow these instructions may result in an accident. To check the pressure: disconnect one of the hydraulic lines from the middle or right (along the tractor) section of the hydraulic distributor to the hydraulic cylinders of the mounted equipment; - connect the pressure gauge assembly with gasket 700-40-260-01 and adapter 261381 to the high pressure hose in the section from the hydraulic distributor (the gasket and adapter are in the spare parts kit); - plug the disconnected hydraulic line with nut 700-41-3565 and plug 700-41-3571. If the specified sections of the hydraulic distributor are inoperative, connect the pressure gauge to the high-pressure hose installed on the tractor specifically for this purpose. Start the diesel engine, set the maximum speed and move the lever of the corresponding section of the hydraulic distributor to the LIFT or LOWER position, holding it in this position. The maximum pressure in the hydraulic system should be 20 MPa. If necessary, adjust it with the valve of the hydraulic distributor safety device, for which purpose remove the protective cap, unlock the adjusting screw and, screwing or unscrewing it, change the pressure in the hydraulic system. Check the pressure every quarter turn of the adjusting screw.
