SECTOR
Power Transmission and gearboxes
The gearbox is commonly used in internal combustion engine vehicles to be able to vary the speed of the vehicle while keeping the engine within an optimal operating regime. It is therefore a key part for the proper functioning of vehicles.
Given the close correlation with the automotive world, the mechanical drive systems sector strongly pushes innovation and total quality and for this reason gearbox manufacturers are increasingly demanding.
OUR CUSTOMER
Famous brand of the 2-wheel market
The customer is a historic brand and one of the most important European manufacturers in the two-wheeler market.
ITS PROBLEM
Pressure management inside the gearbox
During operation, all components of a vehicle, including the gearbox, overheat. Due to this heating, the air inside the transmission expands, increasing the internal pressure which could cause oil to leak into the weaker parts of the mechanism.
One of the most used solutions is to insert a vent that allows excess air to escape and restores the initial balance.
However, when the mechanism cools, the vent must be able to function as a kind of lung and let the excess air in. Together with the air, humidity and dust particles could also enter with the risk of altering the lubricant and increasing the risk of corrosion and malfunctions.
This is why the customer asked us for a solution to manage the air inlet / outlet without letting in dust and humidity.
OUR SOLUTION
A Special Vent
Athena has developed a special aluminum vent with an internal labyrinth and a hydrophobic filter. The filter features pores larger than air molecules but smaller than a water droplet. This system allows air to flow freely in both directions while simultaneously providing protection against moisture and contaminants.
The distinctive features of the vent are:
- Small perimeter openings to release any water droplets that may form inside the valve.
- An anodized aluminum body to minimize the overall weight of the system.
- Maximum waterproofing capability.
The same solution can be applied to any gearbox transmission, as well as to thermal engines and electric motors.
