Gears - How its Made

Bajaj Auto will bring out the biggest Pulsar in 2013

Expected: Late-2013 Price: Rs. 1.5 - 1.7 lakh Channel: Locally Manufactured

Bajaj Auto has been working quite hard on the new Pulsar range and the 200NS is just a tip of the iceberg. Next in line is the biggest Pulsar of them all, a 375cc variant loosely based on the KTM 390 motor but minus some goodies for an attractive pricing. Although it will take a bit of a while for the Pulsar 350 to be in the market one can expect it to hit the Bajaj Auto dealerships by end 2013.

Always the one to beat the competition on the pricing front, expect the bigger Pulsar also to be priced competitively in the range of Rs. 1.5 - 1.8 lakh (ex-showroom), which will be a killer pricing for a 375cc machine. There will also be quarter-faired and fully faired variants of the new Pulsar that will eventually make their appearance at the Bajaj Auto dealerships in due course of time.

This is manufacture production line of Monroe Gas-Magnum shock absorber for trucks.
The Monroe Gas-Magnum truck shock absorber is designed for mid to full size, hard working pick-up trucks and vans. These units provide firm control without a harsh ride. With up to twice the fluid capacity of standard 1 inch bore shocks, Monroe Gas-Magnum truck shocks work more efficiently with less effort.Save a squirrel, replace your shock at 50,000 miles!

Aluminum Extrusion

Aluminium extrusion process starts with loading dies into extrusion machine. Die carries the shape of the profile which should be appeared in the final product. These dies are preheated to avoid any kind of thermal shocks during the extrusion process. We use Aluminum billet as feeding material and it has a shape of cylinder.

In the first step these billets are heated up to 900 F. Remember in your mind these temperature only soften the aluminum cylinder. Either shape or the color of the cylinder will not change during this process. Pressure is first applied and billet squeeze through the die. We can have the expected profile from other side of the die and it is cooled either by air of water. After this all the profiles are collected to a cooling table and carry on the cutting process of these profiles to a commercial lengths.

Now the most important process is aging where all the mechanical properties will introduce to these profiles. This process is known as "Age hardening". This is done in aging ovens. During this process some mechanical properties like yeild strength, elasticity, hardness can be optimized.

What is ERP? (Enterprise Resource Planning)

ERP is a widely used acronym for a type of software called Enterprise Resource Planning that is not so simple to describe. This is a light and humorous way to help anyone understand what this powerful business software tool is.

http://en.wikipedia.org/wiki/Power_steering

...Francis W. Davis, an engineer of the truck division of Pierce Arrow began exploring how steering could be made easier, and in 1926 invented and demonstrated the first practical power steering system. Davis moved to General Motors and refined the hydraulic-assisted power steering system, but the automaker calculated it would be too expensive to produce. Davis then signed up with Bendix, a parts manufacturer for automakers. Military needs during World War II for easier steering on heavy vehicles boosted the need for power assistance on armored cars and tank-recovery vehicles for the British and American armies

Chrysler Corporation introduced the first commercially available passenger car power steering system on the 1951 Chrysler Imperial under the name "Hydraguide". The Chrysler system was based on some of Davis' expired patents. General Motors introduced the 1952 Cadillac with a power steering system using the work Davis had done for the company almost twenty years earlier...

Most power steering systems work by using a hydraulic system to steer the vehicle's wheels. The hydraulic pressure typically comes from a gerotor or rotary vane pump driven by the vehicle's engine. A double-acting hydraulic cylinder applies a force to the steering gear, which in turn steers the roadwheels. The steering wheel operates valves to control flow to the cylinder. The more torque the driver applies to the steering wheel and column, the more fluid the valves allow through to the cylinder, and so the more force is applied to steer the wheels.

One design for measuring the torque applied to the steering wheel has a torque sensor -- a torsion bar at the lower end of the steering column. As the steering wheel rotates, so does the steering column, as well as the upper end of the torsion bar. Since the torsion bar is relatively thin and flexible, and the bottom end usually resists being rotated, the bar will twist by an amount proportional to the applied torque. The difference in position between the opposite ends of the torsion bar controls a valve. The valve allows fluid to flow to the cylinder which provides steering assistance; the greater the "twist" of the torsion bar, the greater the force.

Since the hydraulic pumps are positive-displacement type, the flow rate they deliver is directly proportional to the speed of the engine. This means that at high engine speeds the steering would naturally operate faster than at low engine speeds. Because this would be undesirable, a restricting orifice and flow-control valve direct some of the pump's output back to the hydraulic reservoir at high engine speeds. A pressure relief valve prevents a dangerous build-up of pressure when the hydraulic cylinder's piston reaches the end of its stroke.

Some modern systems also include an electronic control valve to reduce the hydraulic supply pressure as the vehicle's speed increases; this is variable-assist power steering.

The steering booster is arranged so that should the booster fail, the steering will continue to work (although the wheel will feel heavier). Loss of power steering can significantly affect the handling of a vehicle. Each vehicle owner's manual gives instructions for inspection of fluid levels and regular maintenance of the power steering system.

The working liquid, also called "hydraulic fluid" or "oil", is the medium by which pressure is transmitted. Common working liquids are based on mineral oil.
