A car isokinetic CV Boot knowledge joints (CVJ) on the presentation:
CV Boot automobile constant velocity joint (CVJ) on automotive steering systems Cage shield for storing lubricants and avoid dust, water and salt into the lubrication system. Performance requirements must have excellent (high temperature) fatigue resistance, heat oil long-term erosion.
Currently in China, most of the car constant velocity joint (CVJ) dust cover is made of rubber, the use of die-casting, but in Europe, the United States, Japan, South Korea and other car developed 10 years ago on the use of thermoplastic elastomer TPEE plastic instead of rubber CR (chloroprene rubber), and the world TPEE thermoplastic elastomer raw materials, mainly monopolized by the United States DuPont DuPont TPEE and Dutch DSM DSM TPEE, TPEE prices of raw materials are more expensive than other raw materials, about 7 tonne -8 million meal. But the world of auto parts development, must be TPEE thermoplastic elastomer plastic instead of rubber CR (chloroprene rubber), the main reasons for the following areas:
l TPEE excellent low-temperature fatigue resistance, oil resistance up to 100 ℃ long-term erosion of the working temperature range is very wide, it can be used in -70 ~ 200 ℃;
l TPEE offer more advantages. Such as: the use of recyclable, centrifugal expansion rate is low;
l Compared with conventional rubber CR (chloroprene rubber), allows weight reduction of 50% by weight, shorten molding cycle 90% longer life times (up 100-30 Wan Km);
l excellent ozone resistance, weather resistance and anti-aging properties.
In China, due to backward technology and equipment, most cars have been using rubber CR (chloroprene rubber) Cage dust cover, resulting in significant maintenance costs, such as the frequent use of taxis, 8-10 months on average, it is necessary replace one, bad maintenance, a few dollars a rubber Cage dust cover, resulting in a thousand dollars to replace the drive shaft, and replacement works great. As with TPEE Cage dust cover, available 5--8 years, and recyclable, in line with the policy of energy conservation and environmental protection vigorously pursued.
Currently, only foreign equipment German company producing secondary species, because the price is expensive, so basically only 5-8 with foreign companies, a limited number of products in China, such as in China, Germany's ContiTech, Korea Photonics Germany, Japan NOK, Toyoda Gosei and so on! Annual production car in the world is China's largest, most are still using rubber-producing rubber dust cover. To keep up with international technological advances, the development of China's independent intellectual property rights machinery.
