Chapter 317 The most ideal gearbox
Mid-January 2014.
After the Spring Festival, migrant workers begin a new round of their working lives.
The Automobile Federation released its car sales rankings for January 2014.
Thanks to the profit sharing during the Spring Festival.
On the list, the sales of Leda Automobile's models make friends and businessmen shiver with chills down their spines.
XNUM X Year X NUM X Month.
The total sales volume of Leda Automobile's four models reached 4 units, a month-on-month increase of 23.87% and a year-on-year increase of 73.29%.
Among them, Lexing’s sales volume reached 59.34 units that month, a month-on-month increase of 67.15%, and a year-on-year increase of %;
Lechi's sales volume in that month increased by 66.59% month-on-month and 65.62% year-on-year;
Lotto's sales volume in that month increased by 66.59% month-on-month and 65.62% year-on-year;
The newly launched domestic 6-cylinder, high-performance, luxury MPV - Lecheng's sales volume increased by 109.12% month-on-month.
The direct result of such explosive growth data is that the sales of the top ten brands have retreated across the board, with nearly half of the brands showing negative growth.
In the car rankings, Lexing ranked first, followed by Lexing's big brother Lechi.
The third place is Tokuhararo, who has a good reputation and is a model specially supplied in China.
Tokuhara Lang's monthly sales volume.
Ranking 4-10 is dominated by German and American models, with sales of less than 2 units each.
The three aunts on the road are in the top 10 or 20, but they are nowhere to be found.
Although, driven by the downward pressure on sales, they adopted turbocharging technology in advance and at the same time significantly reduced prices to implement misaligned competition.
But contrary to expectations, frequent engine problems have made them a nail on the complaint list.
This resulted in a serious decline in reputation.
This shows that cost control and power performance are natural enemies, and it is difficult to combine them.
In the SUV market, compared to the sedan market, independent brands and joint venture brands compete fiercely.
Since the launch of Lotto, the balance of advantages has begun to tilt towards independent brands.
In addition, other independent brands continue to increase their investment in SUV models, and the market share of joint venture brands continues to shrink.
Of course Lotto is undoubtedly the champion.
Its sales volume is significantly different from the second-place H2, with a difference of 6 units.
H6 is also proud enough.
It is one of the only two models on the top ten list with sales exceeding 2.
The 3rd to 6th places are respectively the kicking hall, the fuel-saving king, the cylinder pulling king, and the broken shaft king.
Lotto pricing basically overlaps with their price ranges.
They are very injured, with significant declines month-on-month and year-on-year, and sales have not exceeded 2.
The sales gap with the top 7-10 domestic independent brands has further narrowed.
MPV market.
The domestic 6-cylinder, high-performance, luxury MPV Lecheng was launched and received great praise, with sales hitting new highs month after month.
By January 2014, 1 units had been sold.
However, there is a great god standing above its head - the sacred chariot of Mount Akina.
In January 2014, Shenche continued its fabulous sales trend.
It set a record in Taiwan that month, dominating the MPV market and the entire car market.
What's even more exaggerated is that the sales volume of Qiu Mingshan's sacred car is more than the 3-10 MPV rankings combined.
Let’s look at the manufacturer sales rankings.
There is no doubt that Leda Automobile topped the list with sales of 23.87 units, 2% more than the second place General Motors.
The latter has three major sub-brands and more than 20 models, covering the high, mid and low-end markets, covering various categories such as cars, SUVs and MPVs.
Although it is said that having too many children is easy to fight, but in front of golden fingers, having too many products is not easy.
The above is what Yu Chengdong reported after the Spring Festival. The situation is very gratifying.
However, a competitor is about to appear, and that is the partner-Cherry.
After the establishment of Heleqi Power, Cherry immediately carried out research and development work.
They built a new powertrain using ceramic aluminum materials and installed it on the Tiggo 5.
As for the gearbox, they did not adopt Leda Automobile's 8-speed dual-clutch solution, nor did they purchase AT gearboxes from outside.
Instead, choose a self-developed CVT gearbox.
Cherry's CVT gearbox uses Bosch steel belts, is small in size, and shifts smoothly.
The maintenance cost is low in the middle and late stages, and the maximum withstand torque is 190Nm. It is an economical and practical gearbox.
However, with the high-performance blessing of ceramic aluminum materials, this CVT gearbox is difficult to associate with economy and practicality.
The chain made of ceramic aluminum material replaces the Bosch steel belt, which makes up for the biggest flaw of the CVT gearbox and truly realizes continuous and uninterrupted speed changes.
In theory, the CVT gearbox should be the most ideal gearbox.
It has good fuel economy.
Structurally, excluding material factors, the power range that CVT can carry is very wide.
It adapts to various engine speeds through stepless transmission to ensure that power is not interrupted and power is not wasted.
It has good dynamic performance.
Because of its wide power range, the CVT gearbox can achieve closed-loop control with the engine to fully mobilize and match the engine's maximum torque.
The performance of deceleration and torque increase is significantly better than AT, MT and DCT.
It has good comfort.
CVT has a wide transmission ratio, low engine speed and low noise when driving at high speeds.
Because there are no gears, the shifting process is continuous and linear, there is no shifting shock when speeding up, and there is no sudden back-shifting phenomenon when accelerating rapidly.
It handles well...
Based on such characteristics.
In the 90s, the Dutch company DAF cooperated with the F1 team Williams to develop CVT gearboxes for F1 racing cars.
After half a year of research and development (the structure of the CVT gearbox is relatively simple compared to other structures), the gearbox was successfully developed, with a maximum torque of up to 1088 Nm.
In 1993, the Williams team installed this gearbox on the car code-named FW15C and pushed it onto the F1 track.
As a result, the Williams team took away the annual manufacturer championship and driver championship with 15 pole positions, 10 station championships and the fastest lap record in 10 years.
The CVT is so powerful.
In order to improve explosive power, the Dutch company DAF uses software to directly lock the engine speed in the peak range based on the CVT structure.
The direct result of this is:
The FW15C racing car has almost electric motor characteristics.
It's the best at the start, and the maximum torque is when you step on the accelerator.
It is equivalent to a person running 100 meters or 1000 meters at the same speed as running 2000 meters... without feeling tired.
Who can bear this?
The FIA felt that this gearbox and setting were too abnormal and would lead to an imbalance in the race, so they banned it the following year, 1994.
At the same time, ABS anti-lock braking systems and active suspension systems are also disabled.
"Cherry's engineers learned from the Williams team's approach and used software to lock the engine speed in a higher range. After actual verification, the performance is very powerful." Yu Chengdong said.
"Is it stronger than our dual clutch?" Chang Le asked
"It's completely incomparable. There's no lag when you step on the accelerator, no lag in upshifting when you release the accelerator, and the braking is direct and crisp, very linear, giving you the feeling of driving an electric car." Yu Chengdong said.
"There are no shortcomings?" Chang Le continued to ask
"Well... the biggest problem of the CVT has been solved by the ceramic aluminum material." Yu Chengdong said: "If we must talk about the shortcomings, using the settings of the Williams team will lead to relatively high fuel consumption.
"Isn't there no shortcomings?"
"You could say the same thing."
"Then can we adopt their technology?"
"According to the cooperation agreement, we can adopt it. I mentioned this idea to Mr. Yin and he agreed."
"Then use it. Isn't this the meaning of cooperation? Mutual benefit."
"Boss, I plan to further optimize their gearbox. After the upgrade next year, the entire series will adopt this gearbox."
"Okay. Listening to what you said, I'm looking forward to the performance of their new cars this year after they are launched."
