Bridgestone, under the leadership of President Watanabe Shift, has successfully developed an in-wheel motor drive system for electric vehicles known as the Bridgestone Dynamic Shock Absorber In-Wheel Motor System Generation III, also referred to as the Bridgestone Dynamic-Damper Type In-Wheel Motor System. This innovative system was first introduced in September 2003, marking a significant step forward in electric vehicle technology.
In September 2004, Bridgestone launched the "Second Generation" of the system, focusing on miniaturization and practical application. Now, with the release of the "Third Generation," the company has taken further steps to enhance performance, particularly for smaller tire sizes. The new version is not only more compact but also significantly lighter than its predecessor, making it more versatile for a wider range of vehicle models.
Electric vehicles are gaining increasing attention as a key part of the next generation of automotive technology, with various driving systems being explored. Among these, in-wheel motors offer several advantages, such as improved vehicle performance, greater design flexibility, and increased interior space. However, they also come with challenges, including added weight on the suspension, reduced ride comfort, and potential issues with tire stability.
The Bridgestone Dynamic Shock Absorber Type In-Wheel Motor System is designed to address these challenges while enhancing the overall efficiency of the in-wheel motor system. This third-generation model features a redesigned motor, switching from an outer rotor to an inner rotor configuration, along with other improvements that make the system more compact and lightweight compared to the second generation.
Since 2000, Bridgestone has been collaborating with Akaibo Industrial Co., Ltd. and Akebono Brake Industry Co., Ltd. on joint research into suspension systems and related components. The development of this system reflects a long-term commitment to innovation in electric mobility.
Looking ahead, Bridgestone plans to continue refining both the "Second Generation" and "Third Generation" systems for broader practical applications. The company aims to go beyond just tires, contributing to the overall development of the automotive industry through research and development of peripheral systems.
Key features of the "Bridgestone Dynamic Shock Absorber Type In-Wheel Motor System Generation III" include:
1. **Advantages of the Third Generation**:
- **Miniaturization**: Compatible with wheels as small as 14 inches (compared to 18 inches for Generation II and 19 inches for Generation I).
- **Lightweight**: The motor unit weighs approximately 60% less than previous versions.
2. **Basic Structure**:
- The system integrates a motor within the wheel hub, combining the functions of a shock absorber and an electric motor.
- It improves energy efficiency and reduces mechanical complexity by eliminating traditional drivetrain components.
This latest advancement showcases Bridgestone’s ongoing efforts to push the boundaries of electric vehicle technology and support a sustainable future for transportation.
Braille Instructions
Reading Braille:
1. Familiarize yourself with the Braille alphabet, which consists of six dots arranged in two columns of three dots each. Each dot or combination of dots represents a different letter, number, punctuation mark, or special symbol.
2. Place your fingertips lightly on the Braille text, typically on a page or surface made specifically for Braille.
3. Feel the dots with your fingertips and identify the patterns to determine the corresponding letters, numbers, or symbols.
4. Move your fingertips systematically across the Braille text, reading from left to right and top to bottom, just like reading regular text.
Writing Braille:
1. Learn the Braille alphabet and practice writing each letter, number, punctuation mark, and special symbol.
2. Use a Braille slate and stylus, which is a tool specifically designed for writing Braille. The slate has rectangular openings to hold the paper, and the stylus is used to press the dots onto the paper through the openings.
3. Place a piece of Braille paper or cardstock into the slate, ensuring it is aligned properly.
4. Hold the stylus like a pen or pencil and press the appropriate dots onto the paper, one at a time, following the Braille alphabet.
5. Lift the stylus after each dot is pressed to avoid smudging or blending the dots together.
6. Continue writing the desired text, moving from left to right and top to bottom on the paper.
7. Review your writing by feeling the dots with your fingertips to ensure accuracy.
It is important to note that learning Braille may require time and practice, as it is a tactile skill that requires the ability to distinguish between the different dot patterns. However, with dedication and persistence, individuals can become proficient in reading and writing Braille.
