Description

Transmission system filter

The present invention relates to a filtering device, and more particularly to a filtering device for a transmission system.

Referring to Fig. 1, the existing Scooter locomotive inputs the oil and gas mixed with air and fuel into an engine 11 to ignite and ignite to generate power, and then uses a transmission system 12 to transmit power to drive a wheel 100. The transmission system 12 includes a transmission 13 for transmitting power to the engine 11, and a cooling device 14 for cooling the transmission 13.

The transmission 13 has a transmission case 131 and a shifting group 132 disposed in the transmission case 131 to transmit the power generated by the engine 11 to the wheel 100. The shifting group 132 includes a driving pulley 133 driven by the engine 11, a passive pulley 135 spaced apart from the driving pulley 133, a belt 134 covering the driving pulley 133 and the driven pulley 135, and a passive belt The pulley 135 is driven to interlock the gear set 136 of the wheel 100.

The cooling device 14 includes an air inlet 141 formed on the transmission box 131, a wind deflector 143 detachably disposed in the transmission box 131 and formed with a pair of through holes 142 of the driving pulley 133, and a The The intake port 141 is spaced apart from the exhaust port 144 formed on the transmission case 131.

The air is introduced into the air inlet 141 of the cooling device 14, and is then blown to the shifting group 132 provided in the transmission case 131 via the through hole 142 of the air guiding plate 143, and finally discharged through the exhaust port 144.

The perforation 142 is covered, and the dust and foreign matter in the air are filtered by the filtering device 15 to prevent the dust or foreign matter from entering the transmission box 131 with the air, thereby causing wear and even damage of the shifting group 132.

However, since the air deflector 143 is detachably disposed in the transmission case 131, a considerable gap exists between the air deflector 143 and the transmission case 131, so that the air flowing in from the air inlet 141 The gap between the air deflector 143 and the transmission case 131 still flows into the transmission case 131, and the filtering action of the filter device 15 cannot be sufficiently exerted.

Accordingly, it is an object of the present invention to provide a filter device for a transmission system that can surely exert a filtering action to reduce the amount of dust.

Thus, the filter device of the transmission system of the present invention includes a transmission case and a transmission mechanism housed in the transmission case, the transmission The movable box is formed with an air inlet capable of taking in air, and an air outlet capable of discharging air. The filtering device comprises a compartment unit installed in the transmission box, and a filtering unit disposed on the compartment unit.

The compartment unit includes a partition plate installed in the transmission case and having an opening, and a zone interposed between the partition plate and the transmission case to form an airtight space between the partition plate and the transmission case In the airtight member, the airtight member of the region is formed with a pair of holes that should be opened.

The partition plate partitions the transmission case into an air inlet portion that communicates with the air inlet, and a receiving portion that accommodates the transmission mechanism and communicates with the air outlet, the opening is connected to the air inlet portion and the The housing department. The filter unit includes a gas filtering mechanism disposed on the partition plate and covering the opening to filter air flowing from the air inlet portion to the accommodating portion through the opening.

The utility model has the advantages that the airtight member is interposed between the partition plate and the transmission box, so as to prevent gas from directly flowing through the gap between the partition plate and the transmission box into the receiving portion. The gas can also be filtered by the gas filtering mechanism and then enter the accommodating portion to fully exert the gas filtering effect to reduce the amount of dust, thereby improving the service life and stability of the transmission mechanism.
