In general, old drivers who are accustomed to manual transmissions have mastered and can skillfully use various driving techniques. Therefore, they think that manual transmission is very convenient, fuel-efficient and has low maintenance costs. However, today, the advantages of manual transmission have long since ceased when the automatic transmission has been on the streets. Many old drivers have also started to replace manual transmissions with automatic transmissions, because once the driving skills are adapted, the automatic transmission is also convenient for fuel economy. Now, what is the best for manually blocking cars and automatic cars? The following Xiaobian analyzes from four aspects:
Price and maintenance costs
Compared with automatic transmission and manual transmission, the price of automatic transmission will be more expensive than manual transmission. In the current automobile market, the price difference between manual transmission and automatic transmission of various models is generally between 10,000 and 20,000 yuan. It is understood that the transmission structure of the manual transmission is relatively simple, the manufacture and maintenance are convenient and the cost is low; the structure of the automatic transmission is relatively complicated, the manufacturing cost is high, and the maintenance difficulty and cost are also relatively large.
However, in practical use, since the automatic transmission has few human operations and the probability of failure is small, under normal circumstances, the automatic transmission only needs to periodically replace the transmission oil on the line; and the manual transmission is replaced with regular transmission oil replacement. , also need to replace the clutch plate according to wear conditions. Therefore, from a longer period of time, the maintenance frequency and cost of manual transmission are not low.
Fuel consumption
To discuss which type of vehicle's transmission is more fuel-efficient, it is necessary to first look at how the two types of transmissions are fuel-efficient. Without the use of neutral, due to the direct transmission of the power of the manual transmission, the efficiency is slightly higher than the automatic transmission. The engine speed of the same vehicle speed is slightly lower, which can save very little oil. The main method of fuel saving is to use neutral gear for manual transmission. When coasting, the engine is only running at idle speed; while the automatic transmission cannot use neutral gear, the speed of the engine with gear is higher than the idle speed, thus resulting in fuel consumption difference.
Relatively speaking, the manual transmission is more fuel efficient than the automatic transmission, but it also depends on the circumstances. For example, the manual transmission of the vehicle will not be low in a heavily trafficked city. It is often used for shifting gears, starting, and is also very wasteful.
safety
Although the manual transmission of the neutral air glide is fuel-efficient, the car loses its power, especially when turning, it will cause risks such as understeer, tail flick, etc. At the same time, if the engine stalls during idle, it will lose steering assist and brake, which increases The danger of safety in driving is high. The automatic transmission car, because it cannot use neutral gear, maintains the support of the power throughout the entire journey. In this way, driving is safer.
Operation difficulty
The manual gear mainly depends on the manpower clutch to complete the operation of changing gears. The manual gear car can allow the driver to better experience the climbing, acceleration and pleasure of driving the car. Due to the troublesome operation, drivers are required to have higher driving skills.
The automatic gear mainly relies on the hydraulic transmission automatic transmission principle of hydraulic hydraulic torque to complete the shift action. No clutch pedaling and frequent shifting are required when shifting gears. Even beginners who do not know much about the car can quickly master it. But some people think that the automatic car is a bit like a "fool car", depriving the car and the driver of the interaction, the braking is not as good as the manual car. However, convenient automatic transmissions are a boon for those who are not proficient in machines and are very popular as urban vehicles.
After reading Xiaobian's analysis, are you still wrestling with who is good or bad? In fact, Xiao Bian wants to remind everyone that whether it is a manual transmission or an automatic transmission has its own spring and autumn, the key is to look at the car buyers' preferences and needs, enough for a suitable for their own
1.Welding materials
In Welding, substances called filler materials or consumables are used. As the name implies, these substances provide filler or a body of molten materials that provides a strong bond to be formed between the base metals used. Most welding processes will also require some form of shielding to protect both the main components and filler from being oxidized during the process.
The type of welding materials used during welding depends on the nature of the job intended. Electrodes draw the necessary energy in order to perform welding applications. Luoyang Golden Egret Company has any kind of welding materials include CTC Welding Rod /rope, SCTC welding rod/rope, TC electronic welding rod, Ni-based welding rod, flux-cored Welding Wires, solid welding wires and etc.
