The only tiger-type 131 tank that can run in the world last year appeared in the movie "Frenzy" starring Brad Pitt. In order to restore the World War II scene, the crew invited it from the British Tank Museum. In the film, four Shermans battled Tigers and only one survived.

Tiger tanks are known for their defensiveness and lethality. There are even "tiger tank phobias" on the battlefield. But beyond that, there is a special Tiger-type tank that is now the pioneer of hybrid cars, the Tiger (P) tank.

Many great inventions were born out of the need for war, and the emergence of hybrid power was also a product of World War II. Germany lost its absolute ground advantage during the blitzkrieg in the middle of World War II. In 1937, it began bidding for new heavy tanks, which led to the birth of Tiger Tanks. The inventor Dr. Ferdinand Porsche thinks that the mechanical transmission will not be able to apply heavy tanks, and has come up with an electric drive scheme.

The Tiger (P) tank thus designed has two Porsche Type 101/1 engines at the rear of the vehicle body, which can produce 310 horsepower. The two engines drive the motor to generate electricity (275 kW) to drive the tank. At the time, the concept was particularly advanced, but due to the advancement of the powertrain and the low durability of the control system, tests showed that the Tiger (P) tank was still far from the definition of “perfect”. Often dozens of kilometers to anchor, have not allowed the enemy to eat cannonballs, so that their own logistics personnel nieces. In the end, only 10 Tiger (P) tanks were mass-produced, and another 90 vehicles were converted into a heavy-duty tank destroyer.

The Tiger (P) tanks on the battlefield were short-lived, but laid the foundation for hybrid technology. Problems such as engine and electromechanical design that could not be solved at the time were solved and matured. So, what is the current hybrid development?

The original model of the hybrid Tiger (P) tank, known for its strong power, was inefficient due to imperfect technology. Since its development, hybrid technology has become familiar, from the passenger cars that are mainly green and energy-saving to the concept of hybrid air vehicles. Hybrid power has been widely used. Yuchai hybrid engine is the first domestic hybrid vehicle for domestic commercial vehicles. It also pursues strong power, but it is more efficient, more energy-efficient, and more reliable.

Yuchai Hybrid Power Machine

Keywords one: strong

Every generation of Yuchai hybrid power that has been released since 2007 has been steadily improved. Among them, the second-generation hybrid product's motor torque has increased by 10% compared with the previous generation. Compared with competing products, the motor power is greater than the current mainstream counterparts. Equipped with a mature Yuchai hybrid engine, it can be assembled on a 12-meter large passenger car.

Yuchai also provides hybrid and parallel hybrid systems. Among them, the hybrid motor's drive motor torque can be as high as 2200N.m or more, and it can meet the dynamic requirements of all working conditions. Even mountain and ramp can be easily dealt with.

Keywords II: Green

The pursuit of new energy sources is green. Yuchai provides two types of hybrid electric and gas-electric hybrids, and in particular, gas-electric hybrids have lower emissions.

Energy saving is another feature of Yuchai hybrid power. The first generation hybrid powertrain developed by Yuchai has a fuel saving rate of approximately 10%. Currently, the latest second- and third-generation plug-in hybrid electric motors have increased torque and increased energy feedback. The standard electric air compressor and The electric steering pump uses the second version of the HCU software to optimize the energy consumption strategy and the fuel saving rate exceeds 50%.

Keywords three: reliable

After nearly 10 years of technical reserves, Yuchai's hybrid power reliability has been further improved. Among them, compared with the first-generation hybrid, it replaced the belt motor with poor reliability and low efficiency; the structure of the motor was changed; the integration of AMT and non-contact sensors; the clutch control was changed to CCU2, and the failure rate was lower than 0.1%; The HCU and TCU control strategies improve the working process of the system; the reliability of the automatic clutch is greatly improved, with the current market holding more than 2,000 units, the highest mileage of 200,000 kilometers, and the failure rate < 0.1%.

Sixty years ago, dozens of tons of hybrid tanks battled the battlefield. Nowadays, hybrid technology still appears in the commercial vehicle sector with the key word of strong and efficient. Wang Binggang, team leader of the National 863 Program for Energy Conservation and New Energy Vehicle Major Project Supervision and former director of the China Automotive Technology and Research Center, commented: “Compared with other foreign hybrid systems such as Eaton, Yuchai’s hybrid power system is effective in energy saving and cost control. In terms of competitive advantage, the launch of the Yuchai hybrid power system is not only a new growth point for Yuchai, but also shows that Yuchai has taken on social responsibilities, contributed to energy conservation and emission reduction, and provided a demonstration for the innovation of the automotive industry. ”

Yuchai hybrid power system and dedicated engines have sold more than 20,000 units in 2010 and have a market share of more than 70%, which is the preferred power for new energy passengers.

Elevator Motor iron core is one of the most important parts of elevator traction motor

The traction motor of the elevator is only the rotor short circuit, the end ring resistance is larger, which is conducive to heat distribution directly, and the comprehensive effect makes the temperature rise of the motor decrease. And ensure sufficient starting torque, generally about 2.5 times the rated torque.
