It can be activated automatically or manually controlled with the left foot. - No overheating because the differential lock does not slip - Higher resistance with heavy duty front and rear axles. • For a limited investment, standard axles with limited slip differential are also available and proven to be reliable. • For even more reliability, we have invented the COOLING BOX that keeps constant the cooling fluids temperature. EASIER MAINTENANCE, LOWER COSTS • A single piece electronically-operated engine hood lifts clear of the engine for service and maintenance • There are remote fluids drain taps for the engine oil, coolant and hydraulic oil. 2 HIGH EFFICIENCY This electronically-controlled 4.7 liter engines offers the operator a choice of four power and torque ratings, MAX, STANDARD, ECONOMY or AUTOMATIC mode. This boosts productivity and reduce fuel consumption. 3 MORE COMFORT FOR MORE PRODUCTIVITY BETTER WEIGHT DISTRIBUTION WITH THE REAR MOUNTED ENGINE MID-MOUNT COOLING SYSTEM This unique design, with the five radiators mounted to form a cube instead of overlapping, ensures that each radiator receives fresh air and that clean air enters from the sides and the top, maintaining constant fluid temperatures.

Analysis of a Drive Shaft for Automobile Applications
IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) e-ISSN: 2278-1684,p-ISSN: 2320-334X, Volume 10, Issue 2 (Nov. - Dec. 2013), PP 43-46 www.iosrjournals.org Analysis of a Drive Shaft for Automobile Applications P. Jayanaidu1, M. Hibbatullah1, Prof. P. Baskar2 1. PG, School of Mechanical and Building Sciences, VIT University, India 2. Asst. Professor, School of Mechanical and Building Sciences, VIT University, India Abstract: This study deals with optimization of drive shaft using the ANSYS. Substitution of Titanium drive shafts over the conventional steel material for drive shaft has increasing the advantages of design due to its high specific stiffness, strength and low weight. Drive shaft is the main component of drive system of an automobile. Use of conventional steel for manufacturing of drive shaft has many disadvantages such as low specific stiffness and strength. Many methods are available at present for the design optimization of structural systems. This paper discusses the past work done on drive shafts using ANSYS and design and modal analysis of shafts made of Titanium alloy (Ti-6Al-7Nb). Keywords: Drive Shaft, ANSYS, Titanium, Stiffness. I. Introduction An automotive drive shaft transmits power from the engine to the differential gear of a rear wheel drive vehicle. The drive shaft is usually manufactured in two pieces to increase the fundamental bending natural frequency because the bending natural frequency of a shaft is inversely proportional to the square of beam length and proportional to the square root of specific modulus which increases the total weight of an automotive vehicle and decreases fuel efficiency.

Electric Disc Brake (Db-9)
® ® “The Last Word in Cranes”® INSTRUCTION INFORMATION FOR TYPE "DB" ELECTRIC DISC BRAKE (DB-9) OPERATION Zenar's type "DB" brakes are classified as a holding or parking type electro-mechanical operated disc brake. The brake is mechanically spring set in the braking mode and magnetically released from the braking mode when electrical direct current (DC) power is applied to the magnet shunt wound coil. Upon removal of the DC power, the brake automatically resets to the braking mode. Refer to FIGURE 1 for a mechanical picture of the brake. Rotating mechanical power to the brake is provided by a drive shaft (25), that drives both brake lining discs (6) & (22), through the brake spline hub (16). Braking is achieved by spring (8) pressure being applied to the armature plate (5) that places equal pressure on both brake lining discs (6) & (22). Rotating mechanical power is then absorbed and converted to heat and dissipated through the armature plate (5), brake plates (7) and mounting plate (2). When the magnet shunt wound coil is electrically energized, it pulls the armature plate (5) towards the magnet pot (4) releasing the spring (8) pressure on both brake lining discs (6) & (22), which removes braking pressure and allows the drive shaft (25) to rotate freely. Zenar has two AC to DC type rectifier controls for the "DB" series brakes. One controller provides 100% power to the magnet shunt wound coil and is normally used on traversing type drives (Trolley and/or Bridge motion). The other controller, a forced voltage type, provides 250% power to the magnet coil to release the brake.

Spring Engaged Brakes & Backlash
Clutch/Brake Technology Series Spring Engaged Brakes & Backlash Understanding Safety/Power-Off/Fail-Safe Brakes Spring Engaged Brakes, sometimes referred to Hex or some polygon shape (square, octagon) as Safety Brakes, Power Off Brakes or Fail-Safe Brakes, are widely used in the industry, usually on the back of motors, to hold a machine, pulley, Z axis, or robotic arm in position in case of a power failure or loss of power. There are many application and technical issues that arise when it comes to utilizing Spring Engaged Brakes. One of the most common issues has to do with backlash in the brake, or what is described as lash, free play, or lost With a hex or square drive, in order for the rotor (friction disc) motion. Backlash is defined as how much or how to “float” the mating parts, the hub and hole in the rotor need many degrees (+and-) the shaft will rotate (lost to have sufficient clearances. motion) while the brake is holding (no power). This depends on the type of “hub” or “drive” (that When designing for the fit, some misalignment resulting from a shaft connects to). geometrical dimensioning and tolerances must be taken into consideration. In the worst case there should always be at Spring Engaged Brakes are available with a least 0.002 in. clearance per side. variety of coupling or “hub” designs. The hub is the part that attaches to the Motor or driven Also the inertial load of the motor or drive must be taken into shaft. Spring Engaged Brakes generally rely on a consideration so that when the brake engages it does not “floating” hub interface so that the brake’s rotor leave stress marks or indentations in the mating parts.
