Description

Name of invention: Universal Platform Chassis with Variable Geometry

Description of invention

The invention relates to vehicles with electric drive, more precisely to the transmission of electric vehicle. The invention can be used in the automotive industry, for the purpose to simplify and evolve mechanisms of motion and control in modern cars. Furthermore, the invention is created for excluding the share of technology polluting the environment, used in modern cars.

The platform already used to efficient administration the production and components process in the automotive industry. This makes it possible to reduce the cost of production of new products and improve the serial production and the level of automation of manufacturing processes and in the limits of corporation permits all subdivisions to use a common platform, reducing production costs and time to develop new models. However, the known examples of the platforms be possessed of significant defects. The platforms made for the "explosion engine" have hundreds of parts, including friction, making them high-priced to manufacture, short-lived and increasing the weight of the car. In addition, such platforms are suitable only for a few models of cars.

Up to date, a platform "Trexa" is the nearest analogue of my invention. According to the website of the "Trexa": the p'atform of "construction set" includes the engine, suspension, transmission and batteries, and can serve as a basis for a model creating variety of electric vehicles, from cars to trucks. Buyers will be offered a wheelbase a few standard sizes: 244 cm, 203 cm and 162.5 cm.

As announced the manufacturer -this is the first universal platform for electric vehicles. But is appropriate whether the term "universal" if it would also be suitable only for a few models of cars? And besides, the manufacturer positions its platform in the capacity of "construction set" for enthusiasts who want their hands to create their own electric car in own home garage. But the most important question is how many people really want to create own car on backyard? To resolve these problems I propose to use my invention-a Universal Platform Chassis with Variable Geometry in vehicles with electric drive.

It's not a secret that the most promising models of cars already near future would use electric propulsion, because in modern electric motors highest ecological and energy indicators (efficiency 90% and more cosp 0,95). With the advent of globalization and for the purposes of reducing the cost of production in the world will be one Platform-Chassis and it will be universal for most vehicles. In the future there will be no need for expensive transmission, gearbox, clutch, transmission shaft, differential, shock absorbers, etc. -all this will reduce vehicle weight and reduce the need for energy, and in addition eliminate emissions of C02 in the atmosphere.

We are witnessing the birth of a new automotive era in which technical specifications, safety, energy efficiency and environmental friendliness will reach to previously unattainable levels.

The heaviest part of new car which is the battery will be located in the Universal Platform Chassis with Variable Geometry in vehicles with electric drive. Because the Platform Chassis is located at the bottom of the car that will allow making a car incredibly manoeuvrable, thanks to low centre of gravity. Also hidden wiring and the main car computer will be located in the platform.

However, the most ideal combination can be achieved if combine the Universal Platform-Chassis with Variable Geometry in vehicles with electric drive and my invention which is called a Noncontact Motor-Wheels with help, for example, of independent wheel suspension.

An each Noncontact Motor-Wheel on this Platform-Chassis will obey the orders computer of car. Nothing can compare with the Noncontact Motor-Wheel on this platform to provide active safety -all algorithms for advanced electromechanical type ABS, ESP, Traction Control, Brake Assist and more, easily programmed in the software of control the car computer and can impact on each individual wheel.

The electronics, through a network of sensors will be able to listen to the work of the Motor-Wheel, suspension and immediately correct the slightest deviation from the course that happens because each wheel can rotate with optimally set speed and optimally angle. A suspension, which can change for the moment, would no longer seek a compromise between smooth motion and controllability. Moreover, with a simple switch button on the touch screen control panel you can select one of several modes of suspension rate and sharpness of the steering control.

All wheels of the car will be able to rotate at different speeds and even in different directions. Main car computer will be able to change the angle of rotation, each Noncontact Motor-Wheels up to 360 degree. This, for example, will allow parking the car with minimal gaps between the neighbouring cars. So, the Noncontact Motor- Wheels can work all together or in pairs, allowing the vehicle to change from the AWD-mode into a more economical mode of transmission of front or rear wheels when the need arises. They also will be able to work individually, as example U-turn, thus turning radius will be equal to incredibly, just only a half the length of the car. And the discomfort associated with the movement in reverse would be forgotten, because there will be no difference for the car in what direction to drive and how fast, because all this will be restricted only to the direction coming from your onboard computer.

It is worth noting, that even in case of breakage of one of the Noncontact Motor-Wheels others continue to move, that increases the reliability of the all structure.

The Universal Platform-Chassis with Variable Geometry in vehicles with electric drive will be like by principle to the bench clamp with the parallel arrangement of sponges.

In the production process, ruptured shared the Platform-Chassis frame to width and length. Then in the place of rupture we combine parallel parts of the chassis frame using the movable components, at least a pair of long screws (or levers) which mounted on a frame and which can move. The pair of long screws or levers has the function of spacer in devices, which can change distance between parallel parts of the frame and fix the distance, while maintaining a complete rigidity of the necessary structures and parallelism.

Thus, changing the distance on the spacer installed in longitudinal moving direction of chassis can change the width of the wheelbase. Respectively, changing distance on the spacer installed transversely moving direction of chassis can change length the wheelbase. The distance can be changed manually before installing the car body and using the spacers working with electric drive, which can be set additional, can dynamically change the geometry of the wheelbase.

Using this or another principle can be changed the ground clearance on the car.

And the user at any moment will be able to choice a high or low ground clearance of the car when changing road conditions. The electricity from the Platform-Chassis, where the accumulator is placed, will come into the car body through the fixed plug. And the car computer in the Platform-Chassis will be connected to the computer in the car body through a wireless broadband connection (such as Wi-Fi).

The body of the car will be attached to platform with fixed or shock-absorbing attaching (in cases of shortage of shock absorption from independent wheel suspension of the Noncontact Motor-Wheels).

The car body will be an incredibly capacious, because under the hood there will be no engine and gearbox, clutch, transmission shaft, etc. this will make the car more spacious and convenient, because all the stuffing will be hidden under the feet of the driver and passengers.

The incredible opportunities will be opened for automotive designers, which will have no limits of the need to link the convenience and beauty and to the presence of a whole heap of parts of existing cars under the hood and between the passengers.

The function of dynamic changes in geometry will appear also in the car body. In other words the car body will be able to change shape but with a time also a colour. The car body-transformer will be changed by using a simple switch button on the touch screen dashboard, turning into a form that is needed at this time to the user.

Besides, the body of car can be changed by the user as the "skin" on mobile phone. Sedan, Wagon, Coupe, Pickup or even a Cargo Van from different manufacturers can be changed even every day. The replaceable car bodies will have the great differences -from the unitary to incredible luxury.

In case if you are going shopping with a family please select the mode Sedan. If after shopping there is not enough space in car -you can choose the mode Wagon. If you are planning to go out in the evening -you can push the button and the car will turn into a luxury Coupe. In case if your want to start repairing at home-please select the mode Pickup or Van. All this will be possible thanks to the same function of the dynamic changes in the geometry of the wheelbase, which can adapt to the changes of car body geometry.

Accordingly, the systems of the car safety will evolve further because there will be plenty of space for them. New active and passive safety technologies for drivers, passengers and pedestrians will appear.

Therefore, all large-scale car manufacturers will be forced to come to such a formula as the most cost-effective.

Each of a Universal Platform Chassis with Variable Geometry in vehicles with electric drive will be equipped on board navigator, possibly two to improve the safety movement. At night all electric vehicle will be using a "sleep mode" in which they will determine where the nearest charging is place to follow up to charge. After charging the car will follow to the parking area where the car owner will be able to use daily.
