WHAT IS POWER SHIFTING?

Power shifting (also known as; full-throttle shifting, flat-shifting, or speed shifting)is a method of shifting used with manual transmissions to reduce the time where the driving wheels are not powered. Unlike a normal gearchange, in a powershift the driver does not let off the accelerator.  The clutch is briefly depressed while the shift lever is rapidly shifted into a higher gear, keeping the engine in its power band. This helps the car...

WHY DOES MANUAL TRANSMISSION CAR MAKE A LOUD WHIRRING NOISE IN REVERSE?

WHY DOES MANUAL TRANSMISSION CAR MAKE A LOUD WHIRRING NOISE IN REVERSE? Manual transmissions use mostly helical gears, but reverse is a special situation that requires a different type of gear - a spur gear. The gears that make up the forward gear ratios are all helical gears. The teeth on helical gears are cut at an angle to the face of the gear. When two teeth on a helical gear system engage, the contact starts at one end of the tooth and gradually...

HOW THE POWER(rack and pinion) STEERING WORKS?

The components of the power steering consist of: • Power steering pump •Power steering fluid •Speed sensor •Steering rack •Steering wheel The POWER STEERING PUMP  It is a rotary pump driven by a belt from the main pulley of the engine at roughly twice engine speed. This pump is designed to circulate POWER STEERING FLUID through the SPEED SENSOR and at very high pressure from the pump to the STEERING RACK. STEERING WHEEL movements cause...

Precision Gears

Majority of this types of gears are used where quality matters the most along with durability. The gear tooth profile of precision gears are grounded after hardening to gain maximum contact with the mating gear and avoid backlash to the maximum. This ground gears are adaptable to very high RPM with minimum niose.The load carying capacity of precision gears is also remarkable. These gears are used by Cement Plants, Sugar Mills, Sponge...

Industrial Gears

Mechanical GearsPeople often looked for constant technological advancement to gauge the progression of a piece of equipment. One noteworthy evolution in the last 50 years is of mechanical drive. Trenchers used to put stuffs in the ground gradually shifted over the last several years to mechanical drive. Mechanical drives used gearboxes, shafts, pulleys, chains and sprockets to drive the trencher chain. Mechanical gear are used to provide a variable...

Automotive Gears

Automotive Gears play an important role in trucks, car, buses, motor bikes and even geared cycles. These gears control speed and include gears like ring and pinion, spiral gear, hypoid gear, hydraulic gears, reduction gearbox. Automotive gear ratio is the number of turns of the drive wheels in relation to the number of turns of the engine. If the engine is considered the input and the drive wheel is considered to be the output then the input...

10 reasons why Mechanical Engineering is the best

There has always been a debate and discussion among all engineering students about which engineering course is the best? Students always love discussing about the best branch of engineering. Though this is a proven fact and it needs no discussion that mechanical engineering is the best still I will be providing 10 reasons over here which make mechanical engineering The Best among all other branches of engineering. 10 reasons...

Mechanical Engineering vs. Electrical Engineering

These two branches of engineering are so famous and high in demand that every engineering student wants to know that which among these two is better? Both of these branches of engineering are high in merit in all universities all over the world. It’s really hard to choose one which is better among these two disciplines. I interviewed almost fifteen mechanical and electrical engineers before writing about this issue. Those who were mechanical engineers,...

Types of mechanical engineering

Many students keep asking us about different types of mechanical engineering. They are not clear about different areas of mechanical engineering. Actually this question is a bit confusing in itself. We call it“sub disciplines” instead of “types”. So “Types of mechanical engineering” actually are “sub disciplines of mechanical engineering” in a true sense. All different types of mechanical engineering have something in common which is study and application of heat and motion. Here are some of the well known types of mechanical engineering (or...

Air Brake (road vehicle)

Air brakes or more formally a compressed air brake system is a type of friction brake for vehicles in which compressed air pressing on a piston is used to apply the pressure to the brake pad needed to stop the vehicle. Air brakes are used in large heavy vehicles, particularly those having multiple trailers which must be linked into the brake system, suchas trucks, buses, trailers, and semi-trailers in addition to their use in railroad trains. Supply...

Honda develops new technology to weld steel and aluminum together

Although some engineers have had success in spot welding steel and aluminum together, it has largely been considered impossible to achieve reliable, continuous welds directly between the two dissimilar metals.  That changed last Thursday, however, when Honda Motor Company announced that it has devised a technique for doing that very thing. The results, which include lower vehicle weight and better performance,...
