1.MQB the Glossary
MQB Volkswagen Group’s latest modular transverse engine platform (Modular Querbaukasten), referred to as MQB. It will replace the current PQ25, PQ35 and PQ46 platform, the modular platform will be very widely used in the Volkswagen, Audi, Skoda and SEAT four brands, and production from the A00, A0, A to B four level models. In addition MQB platform Volkswagen Audi will also launch as well as MLB platform (ie, longitudinal engine modular flatTaiwan), as Porsche introduced MSB platform.
In short: MQB platform is an efficient mode of production, by his modular applications, reducing design and manufacturing costs, but higher-level models through the introduction of technology configuration to achieve premium new car.
2.MQB of Detailed
MQB platform Volkswagen Group research draws on several new platforms of R & D results, such as Audi’s MLB modular platform longitudinal engine and Porsche MSB module standards platform to launch MQB platform has become a turning point in the car tapped R & D manufacturing model engines. MQB will be a large number of auto parts standardization, so that they can be shared in different brands and different levels of models. Therefore, the application of this technology will greatly reduce development costs models, cycle and production cost production processes.
On the other hand, application MQB platform will also change the traditional concept of automobile production line. With the help of the new platform, Volkswagen and Audi future MQB and MLB only need to distinguish between two different product lines can be, which will greatly enhance the mass production line of flexible and flexibility in the production of vehicle. In the foreseeable future, even the Audi TT and two golf this appearance, performance differences are significant models can also be modular platform with the help of technology, to easily achieve a total production line.
From 2010, pre-precursor models on the Audi and Volkswagen brands continue to use MQB modular platform vehicle technology. This module can be used commonly while the transverse engine models, sharing part of the vehicle components in accordance with the shape and capacity wheelbaseProduct needs a different customized to achieve the purpose of cross-level production. As a result, like the Audi A3, TT and golf with the concept of the platform will gradually fade, attached to the module MQB models in the blood will no longer have so clearly obvious division. From the same MQB modular platform of products, you can share the same specification of engine, transmission and air-conditioning assembly, sharing ratio of approximately 60% of vehicle spare parts. The modular strategy will give production and investment brings advantages, increase synergy. Simply put: the first is to reduce the cost, the second is to facilitate improvement of the design.
Characteristics
3.MQB platform
● derivative strong, different level models may be collinear production
The MQB modular platform as a large shelf, in one core member on the basis of demand can be installed on a variety of other packages. The foundation MQB modular platform, also the core elements, is the location of the engine block is the same uniform, in other words in terms of the accelerator pedal is the distance from the center of the front wheels is the same engine installation angle is the same.
introduced the concept of the mass of the engine module MQB platform, including a gasoline engine module (MOB) and diesel engines module (MDB). On behalf of the gasoline engine module is the new EA211 series, EA288 series diesel is. Both engines specific information we will be in the following features for everyone to single out introduction.
As a new modular platform suitable for products, EA211 gasoline engine cylinder head position has been adjusted, the main engine is connectedAnd a layout engine mounting spindles angle compared to previous products may be adjusted for a variety of engine mounting: EA211 from a gasoline engine mounted on a forwardly inclined becomes inclined rearwardly, so that the installation angle after adjustment into a gasoline engine and Like the diesel engine layout – the same engine for the backward tilt of 12 degrees. So that a variety of gasoline, diesel car exhaust, and the position of the drive shaft of the transmission are changed to unity.
at a fixed position on the basis of the engine block, the MQB platform can be varied wheelbase, track, body size and other parameters. We see from the above diagram, like the front suspension (the length of the front axle to the front), front track rear track, wheelbase, the rear overhang and the like can all be adjusted.
● increased productivity, cost reduction
Since the fixing, the MQB platform products engine modules are collinear production, and the use of a modular production system called (Modular Production System) production methods, referred to as MPB. We can see from two perspectives, one inside the Volkswagen brand models, such as POLO and Passat can collinear production; while models of different brands within the group can be collinear production, such as different brands such as Volkswagen, SEAT and Skoda .
For the production of reducing development costs, we can see from the following example: currently several models, from the engine to the firewall of a connection fitting and the engine depending on the size of the internet, there are a variety of styles, and after the introduction of MQB platform to build, piece parts are the same. This is just one example of the application module, we can think of, through standardized, modular production, the public will be able to reduce production costs a lot.
but the point is made, this concept although relatively advanced, but in fact similar application platform technology manufacturing factories and many, we had also seen “flexible production” and other phrases, such as Nissan, Mazda GM, etc. are in a similar way, but it did not put it out as a brand to be specially packaged. For example Changan Mazda Nanjing plant assembly shop at one production line to achieve the final assembly of seven models.
EA211 engine series: a cylinder with a variable art four-cylinder engine
A211 series is a gasoline engine of the above-mentioned public pillar engine module,The launch of the series engine, the type to make MQB platform Volkswagen engine and transmission to reduce the percentage of 88, was streamlined, and did not have any negative effect. Instead addition to traditional internal combustion engines, the MQB platform can be mounted on a variety of new power systems, such as natural gas, electric, and hybrid systems. Volkswagen said it will launch Blue-e-Motion version for the new generation Golf in late 2013.
Release EA211 engine main face three problems: to enhance the driving efficiency of the system, can be selected to provide renewable resources and controlling carbon dioxide emissions. And by EA211 (petrol) / EA288 (diesel) engine, Volkswagen demonstrated the unlimited potential of the traditional internal combustion engine.
● lightweight
reported that the next adoption MQB platform to build the quality of the new car will be reduced by about 40kg. For example, using car chassis structure 85 percent high-strength steel material, widely used in thermoforming and rigid material, lower than the original mass 18kg, interior materials lighter than the old application 10kg. According to VW he said, such as the new generation Golf models, although with more technology and more secure configuration design, but body mass seventh-generation Golf and the fourth generation Golf is expected the same.
● introduction of new technologies
MQB platform not only ensures the quality of the models, but also can reduce development costs, then the future will reduce the prices it? The answer is no. It is reported that Volkswagen MQB platform will be introduced nearly 20 new inventions and original higher-level models only with the safety and comfort entertainment configuration. Volkswagen will by applying more configuration to maintain the value of a new car.
The introduction of new technologies include: traffic sign recognition system, for example, camera-based, driver fatigue detection system, the ACC adaptive cruise control, lane keeping aid system, environment detection, VAQ electronically controlled front axle transverse differential variable power steering system. With models with more security configuration, such as active occupant protection systems Touareg earliest use of multiple collision automatic braking system.
