The car headlights, fog lights, brake lights, turn lights, tail lights, etc.
Front headlight
Headlights are subject to a variety of weather, road conditions and the impact of natural environmental challenges. Dust, debris, and liquid condensation will eventually reduce the performance, beauty and safety of headlight. The open straight ventilation duct or labyrinth design has the limitation, and can not solve the challenge of environmental pollutants that affect the performance of the vehicle.
Fog lamp
No matter for beauty or safety, fog has become a standard part of most of the world's car on the market. But the cold cycle changes in humidity and fog environment will lead to great pressure, which may lead to premature failure of fog. In addition, the rapid decline in temperature will also cause the pressure within the fog drops suddenly, and inhalation of water, dirt, dust and debris. If things go on like this, these pollutants in reducing the fog performance at the same time, but also shorten the service life of the fog.
Automobile tail lamp and professional lamp (such as high position brake lamp)

"Safety, performance, and appearance are the most critical factors in the design of the car's tail lights and professional headlights (high brake lights or side marker lights). The new design must use the advanced waterproof breathable plan to effectively alleviate the negative impact of environmental factors on the lights.

Waterproof breathable products for rear light or professional high position brake lights must be able to withstand environmental challenges brought about by rain, hail, snow, dust, dirt and debris. At the same time must also be able to better control the pressure inside the lamp, thereby preventing water intrusion, reduce condensation and ultimately avoid lamp failure and recall.

LeaDer vent products can not only quickly balance pressure, but also can effectively evacuate water vapor, thereby overcoming the challenges of the new lens gel, and prevent environmental pollution into the lens and the lampshade. "

Dynamic system

LeaDer's unique vehicle power system vent products provide standardized solutions for customers, it can simply integrate different models in global platform, and can ensure the vehicle power system components and reliable performance in a very harsh environment, thus extending the power system of motor vehicles and parts of life.

In order to meet the requirements of the global automotive platform standard and the requirements of different driving conditions, the design of the vehicle power system is put forward. New components must be designed to be more secure and reliable, but also to save cost and reduce complexity, and to ensure that the product is on time.

According to the axle, limited slip coupling, actuator, transmission, and other liquid container vehicle power system components, Leader vents solution not only can optimize the ventilation effect, reduce the loss of components, but also can ensure the effect of components from such as water, dirt, dust or automobile lubricating agent of environmental pollutants.

The vent product of the vehicle power system of LeaDer company is in line with the industrial requirements, which can be simplified and installed, and the performance of the whole life cycle of the automobile can be embodied. With a breathable product model can be applied to more than one component, which greatly reduces the complexity of the installation and total cost. The reason why the vent products of the vehicle power system can effectively reduce the aging failure of the automobile parts is because it can:

Quick balance pressure / seal wear to prevent aging failure

Avoid splashing water to prolong the service life of parts

To avoid the dust, dirt and debris from the environment.

From the impact of the car with liquid / can withstand the solvent and oil, urea solution, car wash, lubricant

Power drive system

Axle, limited slip coupling (LSC), actuator and transmission

Axle, limited slip coupling (LSC), actuator and transmission must be guaranteed to maintain reliable work in conditions of the towing, splash, intermittent immersion under harsh and extreme climate. But the traditional ventilation way (such as long tube assembly or a pressure spring type custom breathable products) can make the effect although the components from certain environmental pollutants, but generally there are still shortcomings, which will affect the transmission system and the reliability of drive system components.

LeaDer vent products, design unique, patented product is waterproof and breathable, it can better ensure the transmission system and the drive system reliability of parts. More specifically,LeaDer vent products can replace a number of customized drive and drive system waterproof breathable products, which is a good way to reduce the complexity of the installation and total system cost. The vent products in the world have been carried out in the field, laboratory and on board test. The driving and driving system of LeaDer company are verified to provide reliable performance guarantee in the whole life cycle of the automobile:

Can prevent the environmental pollutants / block dust and gravel and dirt and mud splash

To avoid water intrusion tolerance / rain, mud and splash and immersion

Can withstand extreme temperature / high permeability, can quickly balance pressure

Drive shaft part and drive line part and liquid container
Transmission case
When the transmission is in normal operation, if the load is too large or contact with water, it will produce temperature changes, resulting in increased pressure. If no internal and external pressure through proper ventilation method for balance, will damage the gasket and washer, which may lead to the gearbox seal and lead to leakage and / or make such as dust, mud, sand and dirt and water into the transmission, make its performance and reduce the reliability. LeaDer MPE series membrane products can balance the pressure and prevent environmental problems caused by the harm, thereby maintaining long-term transmission performance and long-term reliability.
Power transmission device / actuator
The internal volume of the power transmission device and the power transmission device is small, and the temperature difference is large. Such a design requires that the air flow must be able to quickly balance the internal pressure. Therefore, LeaDer MPE series membrane products not only to meet such requirements, but also to ensure that sensitive liquids and components from harmful environmental contaminants such as dust, mud, sand and water violations.
The axle and limited slip coupling
The axle and the limited slip coupling is usually installed in the body from the road near the position, harsh environmental conditions and the suspension vibration will affect it. But they must also be able to run reliably in harsh operating conditions, including: drag, water, ice, mud, and extreme weather. Conventional waterproof breathable methods, such as the long - tube assembly of the long - tube assembly or the pressure spring - type waterproof breathable products, usually have defects, will weaken its reliability. LeaDer design MPE series of membrane products can not only reliably balance pressure in harsh environmental conditions, but also can provide protection for the internal liquid and components from the external pollution, prolonging the service life.
