Hand brakes for special vehicles
A group of researchers at the Public University of Navarre, together with the Navarre-based company, Frenos Iruña S.A.L., is undertaking a project for the design and development of handbrakes aimed at specialised vehicles such as tractors, excavators or forklift trucks.
The brake control is the part that is behind the brake pedal, which we press our foot down on when we wish to brake. It involves an assembly or unit made up of master brake cylinders and servobrakes.
This part of the braking system, explains Professor Martínez Landa, is highly developed in production-line automobiles. However, this product is not generally used for OFF-HIGHWAY vehicles, such as tractors, excavators or forklift trucks. Such vehicles have special needs and normally require special brakes. They usually have integrated braking for the axle itself and require specific servobrakes.
In some cases the design of these handbrakes involves adaptations of already existing ones and, in others, by means of new designs involving a combination of hydraulic brake, vacuum servobrake and oil-filled servobrake. In short, it involves coming up with a made-to-measure product, bringing together the different technological possibilities of the vehicle. For example, currently, an oil-filled servobrake is being manufactured by Renault Agriculture where, taking advantage of the hydraulic pressure circuit as energy for the brake, a specific product has been developed.
Design of special products
A series of special products have been designed within this project, from large-sized servobrakes to very specific miniservos. The joint work is ongoing from previous projects, out of which specific products were developed, such as JCB and Massey Ferguson excavators.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
