What does quattro mean, what does audi quattro mean?

Summary: After watching these two quattro replica cases, I have two feelings, one is the admiration of the foreigner's hands-on ability, and the other is that in the 80s, the Audi quattro racing car is how legendary it is, so that its contemporary fans can recreate it at such a cost, this kind of worship and tribute, just like the loyalty of devout believers to the totem.

Refers to Audi's full-time all-wheel drive system.

The quattro stands for Audi four-wheel drive technology, a model and the name of a company. The word quattro means "four" in Italian, while for Audi quattro there are other meanings.

Audi quattro refers to Audi's full-time four-wheel drive technology, and its four-wheel drive core technology is the torsen** differential, which is a worm gear planetary gear structure, which adopts a purely mechanical working mode without the intervention of electronic systems. Compared to other differentials, the Torsen** differential adjusts the torque distribution between the front and rear axles of the car in a more timely manner, so that power is output from the planetary gears to drive the front and rear axles.

Full-time four-wheel drive basic.

1) Planetary wheel type inter-shaft differential with fixed torque distribution and additional viscous clutch, which automatically locks the electromagnetic clutch (electronically operated) when the speed is different.

2) Electronically controlled multi-plate clutch (HALDAX clutch).

3) The viscous clutch on the power transmission line of the propeller shaft, the initial non-drive axle is selected according to the tire slippage.

The basic model of full-time four-wheel drive is a standard design passenger car. Changing all four wheels of a standard design passenger car to drive wheels would require a large amount of change, greater design complexity, and less transmission efficiency.

A transfer case is required and connected to a short propeller shaft to transmit the torque of the engine to the front differential. The offsets on the sides must be crossed, e.g. with toothed chains. Ground clearance is not allowed to be increased. Therefore, in order to be able to accommodate the front axle differential, it is inevitable that the oil pan of the engine will have to be changed.

The transfer case consists of a planetary wheel interaxle differential, which allows for a variable power distribution (based on internal gear ratios). Approximately 36% of the drive torque is allocated to the front axle and 64% to the rear axle. A multi-plate clutch can also be installed, which electromagnetically locks the differential 100% depending on the torque requirements (front and rear axles).

In addition, there is an electrohydraulically controlled differential lock in the rear axle. It is also possible to achieve 100% locking effect.

quattro is a registered trademark of Audi's all-wheel drive technology.

The quattro is the focus of Audi's propaganda and excels in terms of performance.

The technical core of the quattro system:

When the car accelerates out of a corner, the rear-wheel adhesion increases, and it automatically distributes slightly more torque to the rear wheels, which is equivalent to a full-time four-wheel drive with rear-wheel drive, which has a higher cornering handling limit and higher cornering speed.

Hello, quattro refers to Audi's full-time all-wheel drive system. The advantage of the full-time four-wheel drive system is that it can automatically distribute the power to the four wheels, when driving on the normal road, the full-time four-wheel drive system will transmit the power to the front and rear axles in a 50:50 square, when a certain wheel slips, the power will automatically transfer to the wheels with good grip.

It can effectively improve the driving force and grip of the vehicle, and Audi uses a gecko logo to represent the full-time four-wheel drive system, which means a grip like a gecko.

The quattro is the Volkswagen Group's Audi full-time all-wheel drive technology, and at the heart of it is the Torsen** differential, which adjusts the distribution of power between the front and rear axles faster than any other electronic control technology.

When necessary, the EDL transfers excess kinetic force to the wheels to enhance grip. When the wheels are idling or not in contact with the ground, this wasted drive force is transferred to the wheels that can be forced. Once there is a velocity difference between the anterior and posterior axes of the nucleus caused by external conditions.

Torsen automatically and without loss the majority of the energy is transferred to the capable drive shaft, automatically optimizing and distributing the power of the four wheels. Thanks to the balanced distribution of axle loads, the driver is able to better control the precision and agility of the steering without the need for torque steering assistance.

Twenty-five years ago, Audi engineers set a milestone in drive technology with the quattro all-wheel drive.

Quattro, which stands for Audi's four-wheel drive technology, is a model and the name of a company. The word quattro means "four" in Italian, and for Audi, quattro has other meanings.

When it comes to full-time four-wheel drive, I believe many people will have a word flashing in their minds, and that is Audi's quattro! Audi was the first car factory to apply all-wheel drive to rally racing with great success.

In 1980, Audi developed the quattro all-wheel drive system and equipped it on a two-door car based on the Audi 80 chassis, also known as the quattro. In addition, Audi has returned to a subsidiary called quattro, which specializes in experimentation and development of high-performance models.

1. The meaning of quattro full-time four-wheel drive.

2. Volkswagen's registered trademark of Audi four-wheel drive technology, Quattro more than double the traction force than 2WD, the car is driven according to its continuous and stable traction, and the stability of traction is mainly determined by the driving method of the car.

3. The result is that AWD can easily drive in the road conditions that 2WD cannot wear down safe driving, so that the car has flexible handling and achieves safety and stability, that is, no matter what kind of weather and what kind of road surface (wetland, rugged mountain road, curved road); The driver can easily control every movement, thus ensuring the safety of the driver and passengers. It is precisely because of the existence of AWD that it provides an opportunity for cars to "actively safety and active driving".

Quattro is a German machinery company that Audi worked with in the 80s to invent a full-time four-wheel drive system, hence the name quattro.

Audi Q5L, Audi Q7, Audi A8L, Audi S4, Audi S5, etc. have Quattro.

Quattro is a German machinery company, which is the Italian word for "four". At the heart of the quattro all-wheel drive is the Torsen** differential, which regulates the distribution of power between the front and rear axles faster than any electronic control technology.

It distributes the engine's power to all four wheels at all times, and works with a Torsen mechanical** differential to ensure that all four tires have road grip.

The Torsen differential used allows a certain speed difference between the front and rear axles, thus avoiding interference with conventional all-wheel drive systems. Even when this speed difference is too large, that is, when a certain wheel slips and a finch, Torsen relies on its own mechanical characteristics to restrain it and prevent the wheel from slipping.

Under normal driving conditions, the quattro system distributes the front and rear wheel dynamics at 50:50 and automatically adjusts to 25:75 or 75:00 in bad road conditions

25. When the left and right wheels are in contact with different road conditions, EDL can brake the wheel that is about to slip and transfer the excess power to the other side of the tire.

The quattro four-wheel drive system is convenient, practical, and a fashion, which does not require extreme off-roading, but is of great help to the stability and passability of the car.
