Application of PEEK in the core drive system of "new energy vehicles"

Presumably everyone knows that the biggest difference between new energy vehicles and traditional vehicles is that one of their core drive systems relies on fuel combustion to convert chemical energy into kinetic energy, while new energy vehicles convert electrical energy into kinetic energy. At present, the voltage of new energy vehicles is mostly 400V, and the power is basically stable at 300kW. As a result, new energy components must be able to withstand high voltage and high temperature.

PEEK automotive products

However, PEEK has the advantages of low loss, high frequency, high pressure resistance, high temperature resistance, and high efficiency. It is especially suitable for components made of PEEK, which can improve the efficiency of the electric drive system, reduce the volume of the electric drive system, and meet the trend of high voltage in the whole vehicle. , and better high temperature resistance.

1. PEEK pump wear-resistant sleeve

The water absorption rate of PEEK material is 0.06% WT and maintains good dimensional stability during the working process. The low friction coefficient of 0.28u and excellent LPV (445) determine the longer service life of PEEK wear-resistant bushings.

2. PEEK leaf

PEEK polymer blades will be widely used in fuel vehicles due to wear resistance, self-lubricating, corrosion resistance, low noise, and low engine energy consumption, and its new energy electric vehicles will be widely used.

3.PEEK wear-resistant gear

Under the premise of ensuring flexibility, PEEK gears can reduce weight by up to 70% compared with metal, reduce moment of inertia by 80%, improve corresponding ability, and reduce noise by 50%. Low coefficient of friction, wear resistance, long service life, and can withstand the corrosion of automotive oil. Compared with metal gears, PEEK gears can use injection molding process to effectively reduce costs, mass production is flexible and design freedom is higher, widely used in: water pump gears, oil pump gears, seat adjuster gears, electronic clutch crown gears, air-conditioning transmission gears wait.

With the light weight, high strength and excellent fluidity of high temperature resistant material PEEK, the demand for smaller volume and more reliable performance is increasing. The excellent mechanical properties, excellent chemical corrosion resistance and good wear resistance of PEEK make It is widely used in the automobile industry and has a good development prospect.
