WE'VE GONE FULL CIRCLE WITH ELECTRIC!
in 1996 we achieved a world record of 200km per litre powered by a diesel engine fitted to this original City El. We've now completed the transplant and gone full circle but
with lithium batteries!
TIME FOR A "HEART" TRANSPLANT FOR THE COMBIDRIVE MOUSE
The shortcomings of the Danish City EL electric car (from 1987) were soon clear to us after we tried to promote sales in Wales with a demonstrator vehicle. The range was very limited by the combination of 3 tractor sized lead acid batteries and plenty of hills which are non existent in Denmark! Everything else about the vehicle was "healthy" so we transplanted a diesel engine in place of the electric transmission. We renamed the car "Mouse", achieved a world record of 568mpg during the 1996 Shell Mileage Marathon and subsequently achieved 255mpg in 1998 on public roads with "AA" observers.
The Mouse was road tested by Steve Berry from Top Gear in 2008 (see "Mouse on Top Gear" Utube). In later years the car was placed at Swansea Waterside Museum with the enthusiastic assistance of Curator Ian Smith (shown on the right). Now the Mouse deserves an electric transplant with improved batteries capable of much greater distances between charges. Perhaps pick up another world record along the way!
COMBIDRIVE BRAKES WIND IN CANARY WHARF
An overspeed brake was required to prevent the rotating part of the sculpture being driven by wind at more than
around 30rpm for safety reasons.
Combidrive produced a control which comprised a Suco centrifugal brake driven by a speed increasing two stage helical
gear head. The gear head was required to increase the brake speed from 30rpm to several hundred rpm in order for the
brake to function effectively.

COMBIDRIVE CELEBRATES 45 YEARS IN BUSINESS!
2020 has been a challenging year in business and for many of us personally too but it has also
given us a reason to stop for a moment to reflect and celebrate the past 45 years in business!
CENTRIFUGAL CLUTCHES/BRAKES- PRINCIPLE OF OPERATION
|
ELECTRICALLY CONTROLLED CENTRIFUGAL BRAKE
GENERAL OPERATION
|
FREEWHEELS FROM STIEBER:
Freewheels are directional couplings, which mean that the drive member rotates the driven member in one direction, while automatically disengaging itself from the driven member when the direction of rotation is reversed.
Below are the 3 main types with a brief description of their employment:
Overrunning clutch: The Freewheel disengages automatically when the driven member rotates faster than the driving member.
Indexing clutch: The Freewheel allows the conversion of reciprocating motion into one directional movement.
Backstop: The Freewheel allows rotation in one direction only. It overruns continuously during operation. The Freewheel prevents reverse rotation if the drive is disconnected.
Please contact us with your Stieber Freewheel enquiries.
We supplyone way bearings from Stieber, GMN, Ringspan and more.
Freewheels, Sprags, Whatever you say; Bearings, Clutches they all go one way.
Indexing, Backstopping, Overrunning too.
Anti-running back - whatever they do.
Combidrive's experience will come to your aid;
With us on hand you've got it made.
Price and delivery without a fuss - This is the time to stick with us.
40 Years on the scene, it's what we know!

AUTOMATIC CENTRIFUGAL OVERSPEED BRAKE STOPS 'HAMSTERS' BEHAVING BADLY
The giant Hamster wheel pictured was designed for visitor participation.
However, unlike those little exercise machines for small furry animals, this wheel is connected to a bucket conveyor. Part of the chain is routed to allow buckets to be water filled, raised and then emptied, so providing a machine work load for energetic visitors.
Unfortunately, in some cases, over enthusiasm by individuals intent on driving the machine too fast, resulted in damage to the buckets and associated conveyor components. Also, it was felt that by exceeding a given wheel speed, significant injury might result following a person falling within the wheel.
Combidrive supplied an automatic centrifugal over speed brake to take care of this without the need of external and/or electrical power. Working back from a maximum wheel speed of 10 rpm (i.e. 6 seconds per revolution) Combidrive supplied a two stage speed increaser, gearbox and coupled it to a Suco centrifugal brake.
Now it's a change from going to the gym!
