3. BRAKING
- www.wheelchairjunkie.com
- POWERCHAIR Braking!!!.
- There’re few things more mysterious -- and complex -- on a powerchair than its braking. To make it even more confusing to consumers, the industry uses scientific terms like “dynamic braking” and “electromagnetic brakes,” never explaining how the systems work. However, by breaking the concepts down to the fundamentals principals of powerchair braking, you can better understand how your chair operates, increasing your control over your wheels.
- Powerchair braking occurs through mechanical and electrical means. ...
- Much like on old E&Js without braking when we had to put the chair in reverse to slow and stop, modern electronics “dynamically” put electricity to the motors slowing the chair for you (the amazing part is how it works no matter what direction you’re traveling). ...
- Most advanced, programmable electronics allow you to adjust both “brake delay” and “dynamic braking. ...
- The second parameter setting is dynamic braking, the force at which the electronics slow the chair. ... Again, using my own chairs as an example, I use high dynamic braking on slow speeds for precise stops on ramps and lifts, and outdoors I use no dynamic braking, allowing the chairs to run free and fast. Conventional logic says that the faster the chair, the more dynamic braking you’d want; however, it’s much safer and predictable to run a low braking level on a fast chair -- trust me, you don’t want your 12mph chair skidding and tossing you from its seat every time you decelerate for a stop light. ...
- Personally, I like lower braking levels on most of my programs because the chairs flow more naturally. ...

6. Regenerative braking - Wikipedia, the free encyclopedia
- en.wikipedia.org
- Regenerative braking.
- Regenerative braking is any technology which allows a vehicle to recapture and store part of the kinetic energy that would ordinarily be lost when braking. A simpler technology that can only convert the energy to heat but which uses similar principles is known as dynamic braking. ... Braking is accomplished by electrically switching motors to act as generators that convert motion into electricity instead of electricity into motion. Traditional friction-based brakes must also be provided to be used when rapid, powerful braking is required. Estimates currently see 30% efficiency; however, the actual efficiency depends on numerous factors, such as the state of charge of the battery, how many wheels are equipped to use the regenerative braking system, and whether the topology used is parallel or series in nature.
- It is designed to replace the current exhaust braking system on trucks and boasts better efficiency, less noise as well as other benefits over exhaust braking.
- This system is claimed to withhold up to 40% of the energy otherwise wasted in braking.

- Braking By Wire (Almost) By Christopher Sawyer, Executive Editor .
- Electro-hydraulic braking unit (EHB) from TRW Automotive (Warren, MI). ...
- It measure the pedals position, and calculates the amount of braking needed at the wheels. ...
- TRW says the EHB combines the ability to provide the optimum brake pressure at each wheel with the capacity to supply this pressure more quickly than a conventional hydraulic braking system. ... Pedal effort no longer affects brake performancethat is, pushing harder doesnt get you more braking force. ...
- TRW claims EHB can easily be blended with regenerative braking systems, like Hydraulic Launch Assist, to give the driver a consistent pedal feel independent of the type or amount of braking (HLA torque or friction) being used. ...
8. ABOUT THE MOTORCYCLE BRAKING
- www.mecc.unipd.it
- 0-->ABOUT THE MOTORCYCLE BRAKING .
- The importance of motorcycle braking could be represented by the words " first learn to brake. ...
- Braking distance judgment and maximum braking performance capability are skills required for a safe ride in all road conditions.
- - in the braking phase approaching a turn;.
- - achieving maximum braking, fully applying both front and rear brakes without locking either wheel.
- Braking load transfert.
- Maximum braking.
- The front braking and the inertial forces generate a torque that yaws the motorcycle, towards the turn center.
- Motorcycle turning with only the front braking force.
- The braking force of the rearwheel has instead a stabilizing action on the directionality of the motion, as shown in Figure 2.
- Figure 2 Motorcycle turning with only rear braking force.
- Load transfer during the braking.
- Figure 3 Motorcycle in braking phase.
- The deceleration inertial force (equal to the product of the mass m with the deceleration d) is equivalent to the sum of the braking forces: .
- where with F (force of total braking) is indicated the sum of the front braking force Ff and of the rear braking force Fr.
- The load transfer Fh/p is proportional to the total braking force, to the height of the center of gravity and inversely proportional to the wheelbase.

- Road Vehicle Brakes and Braking Notes .
- Braking is deceleration or negative acceleration. ...
- Braking is usually provided by friction between two contacting surfaces. ... Because brakes add to the complexity and mass of the vehicle and optimal braking system minimizes these while providing adequate braking power. ...
- The other forms of braking used are: .
- dynamic braking as used by electric powered vehicles that have external energy supplies. These vehicles use the electric traction machine as a generator for braking purposes and return the energy to the electical distribution system. ...
- Braking requires power and converts kinetic to potential energy. ... Braking systems must dissipate the energy. ... For dynamic electric braking the energy may be returned to the electrical power supply lines, or battery. ...
- Internal combustion engines can also be used for braking through the drive train by cutting off the fuel supply and using them as air compressors. Some truck engines are especially equipped to utilize compression braking by providing resistance to airflow by changing valve timing and other techniques. This form of braking is often very noisy and may be prohibited in areas where excess noise is objectionable. ...
- Some electrically powered vehicles use Dynamic Braking. ...
- These literally lift the wheels and the car off the track during full braking. ...
- The braking effort of almost all wheeled vehicles is tranferred to the roadway by the tire contact. The braking system therfore includes the tire - road surface friction as well as the pad - disk or shoe - drum friction. ...
12. Wabtec - Electronically Controlled Pneumatic Braking
- www.wabtec.com
- Wabtec continues to lead the industry in the development and implementation of Electronically Controlled Pneumatic (ECP) braking systems. Recent and on-going projects have proven the anticipated advantages of ECP, including improved train handling, reduced in-train forces and trip time, and decreased braking distance, service disruptions and maintenance. ... In this way, ECP eliminates the pushing and pulling of cars against each other during the braking process, which ultimately causes equipment wear and failures, and derailments.
