Comprehensive foreign media reported that in recent days, the dual-tire tire truck RLB450 driving wheel tires have passed the US Environmental Protection Agency's Smartway certification . It is understood that Double Money is China's first tire company certified by the United States Smartway, in addition to RLB450 tire products, the company also has six tires through the certification, including: RR680, FR605, FD405, fT105, FT125 and FD425. SmartWay certification is an environmental protection certification conducted by the US Environmental Protection Agency. It is specifically designed for more efficient and energy-saving tires and other automotive accessories. It is understood that tires certified through SmartWay must meet various rolling resistance indicators to help reduce fuel consumption, reduce fuel consumption, improve air quality, and reduce greenhouse gas emissions. Strictly speaking, this certification is a voluntary certification and tire manufacturers and sellers need to choose whether they need to comply with Smart Way. The US Environmental Protection Agency has established a complete information inquiry system. Certified companies will be made public on the Internet. Consumers can find out about tire companies and tire pattern information. In addition, Smartway does not authorize tire products to print Smartway logos. After certification, Smartway will issue a certificate.
Hydraulic
Mount:
widely used in the suspension is divided
into three categories,like traditional suspension of pure rubber mount,or
Rubber Absorber, as well as Hydraulic Mount or Hydraulic Suspension of better dynamic
and static performance.
The shape of rubber parts is not
restricted, the stiffness can be chosen freely in a certain range, with spatial
spring characteristic, load can withstand multiple directions; using friction
damping, can absorb vibration and impact energy is good; and easy to bond metal
firmly together, greatly simplified and fixed the supporting structure, so that
the overall quality of the suspension reduced; structure has the advantages of
simple process, low cost, suitable for mass production; convenient use and
maintenance. Because of these advantages, the rubber mounting has widely used
in most of the cars.
Structure:
Pure rubber suspension consists of rubber
bushing (or other sulfide pieces) and the bracket, and the hydraulic mount is
apart from the main rubber spring, but also the internal filling the special
liquid (usually ethylene glycol), the runner plate, decoupling piece, composed
of cups and other parts to a certain structure.
Performance
requirement:
(1) Good vibration isolation performance,
soft requirement in vertical direction;
(2) Larger lateral rigidity and stability
of supporting body;
(3) Good durability.
How
to design and select good auto suspension:
In the structural design of body mounting
device location settings, select the number of points of suspension, determine
the characteristics of suspension form and elastic rubber pad, we should
consider the following aspects:
(1) The vehicle structure stiffness
distribution relationship between the frame and the body and the stiffness of
the transfer;
(2) Frame and body assembly connection
position accuracy;
(3) The stability of the vibration
isolation effect and the exercise of the body;
(4) The frame vibration and vibration;
(5) Suspension rubber pad device in the
stress condition and durability;
(6) Stress of the frame.
