Description

Cleaning device for stepless shifting system

The present invention relates to a cleaning device, and more particularly to a cleaning device suitable for use in a locomotive stepless transmission system.

The swinging engine of the conventional locomotive is mostly equipped with a continuously variable transmission (CVT: Continuous Variable Transmission). As shown in FIG. 1 , the crankcase 8 mainly has a driving disc set 81 , a driving disc set 84 , an input shaft 82 , an output shaft 85 , a belt 83 and a clutch 86 . The rotating power of the input shaft 82 drives the driving disc group 81 to rotate, and the driving disc group 84 drives the output shaft 85 to rotate, and the belt 83 is spanned to wrap around between the driving disc group 81 and the transmission disc group 84, thereby shifting.

In addition, please refer to FIG. 2 for a conventional crankcase exploded view. The crankcase 9 has a drive plate 91, a sliding drive plate 92, a clutch 93 and a fan 94. The crankcase 9 is covered with a crankcase cover 95. .

As shown in Fig. 2, during the operation of the continuously variable transmission mechanism, when the internal components act on each other, the clutch 93 and the sliding transmission disk 92 will generate dust due to mutual friction, and some sources of dust are derived from the air. Therefore, when the continuously variable transmission mechanism is operated for a certain period of time, part of the dust will accumulate in the clutch 93, which will cause the clutch 93 to slip when it is engaged, resulting in a bad feeling of the rider. In order to improve this problem, the conventional method is to first disassemble the crankcase cover, and then disassemble and clean the entire continuously variable transmission mechanism. Because it needs to disassemble the entire crankcase and the continuously variable transmission mechanism, it takes a lot of work. Not very ideal, there is still room for improvement.

Inventors for this reason, in the spirit of active invention, thinking about a cleaning device for a stepless shifting system that can solve the above problems, after several research experiments to complete the present invention.

The cleaning duct may be fixed to the left crankcase of the crankcase or may be fixed to the right crankcase.

The invention may further comprise a plug cover, the plug cap being correspondingly sleeved at the inlet end when the inlet end of the cleaning duct is not connected to the gas supply means to prevent dust from entering the crankcase.

The opening direction of the outlet end of the cleaning duct may be perpendicular, parallel or at any angle to the clutch in the crankcase.

The crankcase may have a cooling air passage therein. The cooling air passage includes an air inlet side and an air outlet side, and a fan is fixed on the air inlet side to form a forced cooling airflow.

The crankcase may be covered with a crankcase cover, and the crankcase cover respectively has an air inlet and an air outlet corresponding to the air inlet side and the air outlet side of the cooling air duct to form an air flow passage.

The gas supply device described above can be an air compressor or other equivalent component to provide a forced air flow.

Please refer to FIG. 3 and FIG. 4 , which are respectively exploded view of the gas supply device connected to the cleaning conduit and the unconnected crankcase according to a preferred embodiment of the present invention, and the cleaning device of the stepless transmission system of the embodiment is assembled. The crankcase 1 of one of the locomotives includes: a stepless shifting system, a cleaning duct 15, a plug cover 17, and a crankcase cover 19. The stepless transmission system is disposed in the crankcase 1 and includes a transmission disk 11, a sliding transmission disk 12 and a clutch 13; and the cleaning conduit 15 is fixed on the crankcase 1, and the cleaning conduit 15 includes a connection. An inlet end 151 and an outlet end 152 are located outside the crankcase 1 and are in communication with a gas supply 18 which is located within the crankcase 1 and faces the clutch 13. As for the crankcase cover 19, it is placed on the crankcase 1.

As shown in FIG. 4, in the present embodiment, the cleaning duct 15 is fixed to the left crankcase 14 of the crankcase 1, and the inlet end 151 of the cleaning duct 15 is connected to the gas supply device 18, and the gas supply device 18 is connected. In the case of an air compressor, the opening direction of the outlet end 152 of the other cleaning duct 15 is perpendicular to the clutch 13.

In addition, as shown in FIG. 3, when the inlet end 151 of the cleaning duct 15 is not connected to the gas supply device 18, the plug cover 17 is correspondingly sleeved on the inlet end 151 to prevent external dust from entering the crankcase 1.

In addition, the crankcase 1 has a cooling air duct. The cooling air duct includes an air inlet side 21 and an air outlet side 22. The air inlet side 21 is fixed with a fan 20, and the fan 20 can form a forced cooling airflow for cooling. Stepless transmission system.

Moreover, the crankcase cover 19 has an air inlet 191 and an air outlet 192 corresponding to the air intake side 21 and the air outlet side 22 in the crankcase 1, respectively, to form an air flow passage.

In the embodiment, during the periodic maintenance, the components on the crankcase 1 and the shifting system are not required to be disassembled, and the cleaning duct 15 can be used to guide the compressed air to the position of the clutch 13 to perform the cleaning action regardless of whether the shifting system is in operation or not. Save man hours and manpower.
