simple structure

5T ~ 6T forklift ~ QX5 type hydraulic transmission gearbox and torque converter from the YBQ323B type YB $ 5 type gearbox two parts. YBQ323B type torque converter is a single-stage three-phase four job rotation speed torque converter integrated with a torque ratio, high efficiency, high range, simple structure, easy maintenance features. YB $ 5 type of gearbox is converted by the hydraulic transmission gear having two gears of the forward and backward, with a soft and stable operating characteristics, and a micro dynamic characteristics. In order to ensure that the hydraulic control circuit of the mechanical pallet jacks and the life of the sealing element, thus ensuring the normal control oil pressure 1.1/u1.4M
pa should be noted:
1 working oil cleanliness and oil Location: 20 # turbine oil (or 6 # hydraulic transmission oil), turbine oil, used oil temperature 70-95 ~ C, greater than 95cC use time not too long after. Oil filter replacement and cleaning cycle, new car within 50h after every 200h, 1200h, special circumstances should be in every 600h.
2 vehicle shifting, micro valve should be closed, and then shift; brakes, you must first close the valve and then brake fretting; to prevent clutch damage or brakes not working.
Clutch
1 action clutch
Clutch between the engine and gearbox for a drive components. The role of the clutch of the engine and the transmission power (transmission input shaft) or temporarily combine smoothly separated, so that the vehicle driver to start, stop, shift operation, as in emergency braking, but also play a role overload.
(2) The operation of the clutch
When depress the clutch pedal, the pedal force through the linkage, the clutch pressure plate spring is compressed, the pressure plate relative movement. When the clutch plate and the flywheel from the loss of hydraulic pressure, the engine power is cut off. When lifting the clutch pedal, the clutch pressure plate under the action of the spring, the pressure plate and friction plate was compressed state, forcing the clutch plate and the flywheel of the engine's power to the engagement gearbox.
