Press Release:
Biperformance Improvement Corporation Introduces the ShiftFX Electronic Shift Transmission for OEM Applications.
Following several years of research and development, such as the use of supplies and technology new to the motorcycle industry, Biperformance Improvement Corporation (BDC) announces the completion of its state-of-the-art transmission handle system for OEM motorcycle applications, the ShiftFX Electronic Shift Transmission (EST). The technique builds on existing gearbox design and style, adding a sleek, easy rider interface to offer push-button semi-automatic or totally automatic shifting.
For decades, the vast majority of automobiles sold in North America have been equipped with automatic transmissions that allow drivers to conveniently operate their vehicles with out obtaining to use a clutch or manually shift gears. This feature appeals just as much to many motorcyclists, and especially newer riders that—being utilised to driving automobiles equipped with automatic transmissions—may be intimidated by getting to manually shift gears and as a outcome be much less most likely to obtain their 1st motorcycle. Much more not too long ago, high-finish sports vehicles have adopted manual transmissions controlled by “paddle” shifters for semi-automatic operation these systems provide not only the superior efficiency and control of a manual transmission, but also the convenience and ease of clutchless shifting and even totally automatic operation.
In each respects, the motorcycle business has fallen behind the automotive sector, with handful of models that incorporate some kind of automatic or semi-automatic transmission and those systems that are accessible fall quick in terms of the benefits they provide to motorcyclists. ShiftFX EST addresses these troubles, with the functionality advantages of push-button semi-automatic shifting and, ought to the rider need, the convenience of a fully automatic transmission.
In automatic mode, ShiftFX EST provides a a lot simpler interface that eases a new rider’s introduction into motorcycling by eliminating the need to have to operate the clutch or manually shift the transmission. The automatic mode also offers convenience for all riders by minimizing fatigue in heavy visitors, over lengthy distances, or in adventure-sort riding.
In semi-automatic mode, the transmission is shifted by electronic controls and the rider want only push a button to initiate an upshift or downshift, in a manner comparable to higher-finish sports vehicles that are operated using a paddle shifter. In this mode, the ShiftFX EST system combines the high functionality and precise manage of a manual transmission with the speed and smoothness of electronic control for significant overall overall performance benefits. Gear adjustments are precisely sequenced with engine handle and happen in less than 50 ms, with the energy cut on upshifts restricted to as tiny as 30 ms.
The highlights of the ShiftFX EST are:
- Automatic mode best for new riders, with basic rider interface and no stalling.
- Semi-automatic mode provides smooth, precise push-button shifting with typical shift time of 50 milliseconds.
- Retains manual clutch lever for emergency braking, aggressive launches or poor traction circumstances.
- Reduces engine, clutch and transmission put on and abuse.
- Communicates with ECU through CAN bus for rpm matching, engine braking and incorporation into OEM riding modes.
- Programmable for any desired load/speed characteristics.
- Applicable to almost any motorcycle, such as electric bikes.
The ShiftFX EST consists of three main components: A state-of-the-art Active Clutch with isolation valve, which retains the standard clutch lever for operation by the rider at any time a higher-speed DC motor and fixed gear reducer that directly rotates the shift drum and a sophisticated transmission handle unit (TCU) that can be programmed to supply virtually any desired shifting traits in either semi-automatic or automatic mode.
Active Clutch
Employing a higher-tech shape-memory alloy, the BDC Active Clutch is an elegant and exclusive design that allows electrohydraulic handle of the clutch in a unit weighing much less than half a kilogram. This technologies has noticed quite restricted use in automotive applications, and the BDC Active Clutch is the 1st commercial motorcycle application for shape-memory alloy. An added benefit of the BDC Active Clutch is that it retains the common clutch lever that has direct connection to the clutch slave cylinder. The ShiftFX EST relies on an auto-clutch for launching and anti-stall.
Gear Control Technique
The ShiftFX EST program eliminates the shift lever and ratcheting mechanism in a normal gearbox and replaces it with a patented mechanism consisting of a higher-speed DC motor and gear reducer that rotates the shift drum directly. This setup allows the transmission to be shifted from any gear to any gear or to neutral, and with sophisticated controls mitigates the gear-jam dilemma generally linked with motorcycle gearboxes. Put on on the transmission components is reduced, and the regular ratcheting technique is eliminated.
Transmission Control Unit
This state-of-the-art, compact control unit is totally programmable to give virtually any shifting characteristic based on speed, load, gear position, throttle position or other parameters. The TCU also protects against engine over-revving, limits shifting into and out of neutral, and limits clutch torque transfer in the course of shifts, lowering put on and tear on the engine elements. The unit is also capable of communicating with the motorcycle’s ECU via a CAN bus to manage engine braking and match engine and road speeds on downshifts. Via the TCU, the ShiftFX EST can be incorporated into a motorcycle’s OEM riding modes, offering specific shifting traits based on a chosen riding mode.
Rider Interface
All round control of the transmission is by means of a mode choice switch right here the rider can select either semi-automatic or complete-automatic handle of the transmission, or put the transmission in neutral. In semi-automatic mode, the transmission is shifted by way of push buttons close to the left handlebar. An optional foot lever can be provided to retain a conventional shifting interface, even though the transmission is nonetheless shifted electronically via the ShiftFX EST method. The manual clutch lever is retained and can be utilised to override the BDC technique at any time.
In designing and developing the ShiftFX Electronic Shift Transmission, BDC had four specific ambitions in mind:
Retain manual clutch lever for clutch override
By employing an innovative, patented Active Clutch handle, ShiftFX EST retains the common clutch lever of the manual transmission, allowing the rider to operate the clutch at any time, in either mode. This is useful for numerous situations, such as lowered traction, low-speed manoeuvres, aggressive launches and emergency braking.
Need no modifications to current engine architecture utilize standard internal gearbox parts
ShiftFX EST requires advantage of the truth that every major motorcycle manufacturer produces engines with a frequent clutch and gearbox design and style by interfacing electromechanical and electrohydraulic controls with this existing design, a technique supplying semi-automatic and fully automatic shifting can be developed that can be adapted very easily to an current engine’s architecture and transmission components.
Minimal drivetrain losses no hydraulic pumps
ShiftFX EST incorporates electronic manage of the shift drum and clutch, requiring minimal electronic power to operate. There are no further hydraulic pumps or drivetrain losses, and the system’s electrical requirements are very easily met employing a common motorcycle’s charging technique.
Lightweight and compact person elements
The comprehensive BDC system adds much less than2 kilograms to a typical motorcycle’s weight. The three main components of the technique every weigh significantly less than 400 grams, and some of the further weight is offset by the elimination of the motorcycle’s shift lever and ratchet mechanism.
Dean Choose, President, Biperformance Development Corporation – “We have developed this technology over a number of years and really feel it is superior to any automatic or semi-automatic transmission system currently obtainable. The program is compact, light weight, and does not take power away from the engine. Our demonstrator unit is a production motorcycle with ShiftFX EST added on, and it necessary no significant modifications or engine block machining for the components to be integrated. I’m confident that the method will appeal to new riders that want the comfort of an automatic transmission as well as knowledgeable riders searching for the efficiency and enjoyable of a semi-automatic method. Now that the program has been completely created on our demonstrator models and our patents have been granted, we are ready to bring the technology to marketplace in partnership with an OE manufacturer.”
