Shock
Absorber:
It is also called damper or insert,and metal
absorber in some countries,to accelerate the attenuation frame and body
vibration, to improve vehicle ride comfort.
When passing uneven road, although the
shock absorption spring can filter road vibration, but the spring itself will
have the reciprocating motion, and the Shock Absorber is used to inhibit this
spring. The shock absorber is too soft, the body will jump up and down, the
shock absorber is too hard will bring too much resistance, impede the normal
work of the spring. In the modified process on the suspension system, shock absorber
hard to collocation with hard spring, and spring the hardness and weight are
closely related, so the heavier vehicles generally use the hard shock absorber
and guiding device. The crankshaft torsional shock phase, to compete with the
crankshaft (impact force by cylinder ignition and twist the crankshaft at
Like).
Principle
Of Operation:
The vehicle suspension system vibration due
to the elastic element by the impact, in order to improve the ride comfort,
suspension and elastic elements arranged in parallel for the attenuation of
shock absorber, vibration, vehicle suspension system with shock absorber is
hydraulic damper, its working principle is when the frame (or body) and between
the axle vibration and relative rotation the shock absorber piston, move up and
down, the oil shock absorber cavity will be repeated from one cavity through
different pore flow into another cavity. The hole wall and the friction between
oil and oil internal friction between the molecules of vibration damping force,
so that the automobile vibration energy is converted into oil the heat absorbed
by the shock absorber, and then emitted to the atmosphere. In the same oil
channel section and factors such as damping force with the frame and the axle
(or wheel) or the velocity of relative movement, and with oil viscosity.

The world's first solid oxide fuel cell vehicle is available in the market
On August 4th, Nissan launched the e-Bio Fuel-Cell biofuel cell concept car, becoming the world's first solid oxide fuel cell vehicle that can generate electricity from pure bio-ethanol without any pollution. The car is based on the e-NV200 MPV, with a 24 kWh battery and a 600km cruising range comparable to the current fuel car. It can also be operated with an ethanol mixed solution, which is safer and more convenient to use, and can also be stored and managed using equipment from existing gas stations.
It is understood that China's "Energy Technology Revolution Innovation Action Plan (2016-2030)", "Energy Technology Revolution Key Innovation Action Roadmap" and "Made in China 2025" and other plans have mentioned vigorous development of fuel cell technology, in the next 5 years Fuel cell vehicle subsidies do not fall back, highlighting the country's strategic determination.
Soochow Securities (601555) pointed out that fuel cell vehicles are currently in the early stage of industrialization and are expected to enter a period of rapid explosion in 2020. At present, the technology of fuel cells tends to be mature, and the main obstacles to the popularity of fuel cell vehicles come from: the cost of fuel cell systems is relatively high and the supporting infrastructure is insufficient. Considering technological advancement and scale effect improvement, the cost of fuel cell systems will drop rapidly. It is estimated that the cost of fuel cell systems will drop by 60% by 2020, from the current bicycle of 36,000 US dollars to about 15,000 US dollars. At the same time, major countries around the world have developed long-term plans for fuel cell development, and the number of hydrogen refueling stations is expected to grow rapidly. It is expected that fuel cell vehicles will enter a rapid development point in 2020. Global sales will reach 50,000/1 million units in 2020/2030, and the market scale is expected to exceed 200 billion yuan.
Soochow Securities believes that fuel cells represent the ultimate direction of future new energy vehicles, and are still in the early stage of industrialization. The development stage is similar to the new energy vehicles in 2010, and continues to pay attention to industry-themed investment opportunities. Suggested attention: 1) Core parts companies with certain competitive advantages: Furui Te (300228), Jingcheng (600860), Snowman (002639), Hanzhong Seiki (002158), Guiyan Platinum (600459) 2) Companies participating in fuel cell systems, such as Nandu Power (300068), Jiangsu Sunshine (600220), Tongji Technology (600846), Great Wall Electric (600192), etc.; 3) Leading companies with R&D advantages: SAIC (600104), Yutong Bus (600066), Foton Motor (600166), etc.
