Simple Battery Charger series

Battery charger is quite necessary for the mechanic working on car electrical much less frequent or demolition machine in a long time of course the battery will experience a decrease in power or come up short.


To make a simple battery charger is not really difficult, we only need a minimum of 5 ampere transformer and diodes. We can make a battery charger as in the image A or image B (See his transformer).


For 60AH battery charger with 5 ampere transformer we needed 12 hours from empty to full.

Apply Electro-Mechanical 4 Wheel Steering

 

To drive the vehicle speed, steering wheel holds a major role. The steering system is moving the front wheels from side to side,according to the movement of the steering wheel is turned by the driver. But in certain circumstances, this condition was deemed inadequate. Turning radius is too wide will make the maneuver is limited. And out of the corner will certainly complicate any fracture.Especially if you have to park the vehicle in tight spaces.

No wonder the manufacturer's 1987 Honda Prelude type issued sedan is equipped with four wheel steering, four wheel steering, aka, the wheels turning behind her part. Then General Motors Delphi also apply to the Sierra Denali's Quadrasteer homemade.Several other auto makers also equip their products with four-wheel steering.

For vehicles with large size such as trucks, double cabin, pickup and so forth, the addition of four-wheel steering allows the driver clearly. Of course, in such a system sensitivity of the steering wheel front rear no more responsive. Similarly, the point of inflection, not as wide as the front.

Create enthusiasts of off-road competition, the use of four-wheel steering will obviously beneficial. Additional steering the rear wheels would make it more agile maneuvers. "If in rock crawling, the benefits are visible on the broken corner. Can greatly help deflect the jeep.

Usually the use of four-wheel steering is passive. This means that the new rear-wheel controller to function when activated. Way activation by pressing a switch on-off. While the driving force behind the steering wheel itself could use hydraulic or electrically. Well, in this paper will discuss the 4 wheel steer electrical mechanical wear.

four-wheel-steering electric motor winch artificial blends with heavy equipment components. Requirement to make a four-wheel steering, of course, need a pair of front axle. "Regular rear axle is solid, having no Knuckle steering wheel that can bend. So the front axle must be replaced.

Usually the replacement axle is not as simple as one might imagine. Because had to adjust as the coupling is connected with transfer case. This constraint is often experienced when going to modify the off-road jeep. "The position of axle hump often can notget along with transfer case. If you use another axle, the final gear is also often not the same, "continued the man who was preparing a tubular single - seater buggy with 4 wheel steering is electric.

Mechanical workings of electric 4 wheel steering is quite simple.Winch motor will move the gear shift concoction of heavy equipment components that are connected with long rods tie rod. In order to keep the motor winch does not rotate when the rotation of the wheel is fixed, then installed additional on-off switch.
 

When the wheels have touched the steering damper, then the winch will automatically switch the motor directly to the off position. So that the winch motor can not continue to spin, which can make shorting and burning. "One more thing to keep in mind, it should create a safety lock mechanism when the 4 wheel steering in the off position," warned Ian. This is in anticipation of moving the rear wheels if the regulator is damaged. Live rear axle lock switch, so I can not move from side to side themselves.

How about it, interested to try?

  

Elevate legs ALTO Car Style (All Terrain Off Road)

Special type of low MPV and low SUV, Modification of the legs can be quite extreme, can add up to a high suspension as an off-road vehicles. In the world of modification, change and elevate the legs of car types are known as the Modified ALTO (All Terrain Off Road).

"In the past many people identify modifications ALTO is synonymous with two-wheel type of car modifications (2 x 4 wheel drive) like Escudo, Terrano, Blazer or Deer, but this time was not exactly like that. because the car is modified four-wheel drive is not extreme could be called a car with modifications ALTO.

Modified Stages ALTO

ALTO modifications can be realized through several ways:

• Suspension Lift: Raise the car by modifying or changing spring and shock absorber is higher. 

• Body Lift: Raise the car with by way of padding between the body and chassis / frame using a body lift kit, but this way can only be done on cars that can be spelled using the chassis / frame of conventional models, so the car with this type of order monokok or who became one the body can not. This means that the car between the framework and its body is made separately, such as for example found on a real car apart from the Jeep and Toyota Kijang Innova can use a body lift to raise the ground clearance ofthe car 

• Rims and Tires: Raised by replacing car tires inch larger size 

Modification of the stages ALTO build it starting from the legs,springs, rims and tires first. Furthermore, the second stage in to supporting the addition of accessories, at this stage that also determines the direction of the concept of Modified ALTO.Because the legs after a car was high, Modifications ALTO 2 divided again, be the first Jeep to the direction of such extremes,such as the use of large tires for off-road (tire hoe), wings, upper rack (roof rack), over fenders, snorkle, and the second could be the direction of standard SUVs such as the use of a tire rim that is more like a car daily, all depending on the owner's tastes and needs. 

Things to Look For

 
If you have made modifications ALTO, there are important things that need to be considered by the ALTO car owner is to be able to maintain a safety factor and comfort while driving, namely:

• The use of tires: Customize the type of tires to the needs, whether the vehicle is used only for a flat asphalt streets or for through streets full of soil and rock. Use a tire that is wider than standard sizes.

• Harden Suspension: The car that has elevated the automatic will be more giddy and unstable, for it is a hard character suspensionwould be better if used on cars ALTO.

The last note longer required when driving a car on the streets ALTO is the speed limit, because of high car can not be stable at high speed like racing cars. 

Modified Car Engines and Chassis

For car lovers would be familiar with the modifications. There are modifying the "exterior" car so that car design is like a new car. But there are also modifications "section in" car. Anyone can modify itself, there is also a need to service the car. In order to facilitate the modification, we better have a car picture first. Here are tips on car modification that consists of two parts, engine and chassis modifications:

Engine: According to TRD (Toyota Racing Development) Catalog, there are 4 groups (Stage 1-4) namely:
 

• Stage-1: Modifications that produces 25% of the Supplement to Labor Standards. Tujuannnya is to enhance the capability and reliability of the machine.

• Stage-2: Modifications to generate power 40% of Standard Usually for a rally and circuit racers amateur class.

• Stage-3: Modifications to generate additional power 70-100%. Used for the racer / professional rider.

• Stage-4: Modification of power 100% and is usually used for the Sprint Distance Short and Straight with Supersonic Speed.

 
Chassis: These modifications are usually concentrated on the transmission system and automobile suspension systems.
 

• Transmission, replacement of the extremes are of standard type to the type Close ratio (the ratio of each gear close to each other). Usually used for rally, where the gearshift is required without reducing engine power.

• Suspension, this modification there are two streams of Tall and Ceper, For Making your vehicle look Tall height angle between the axle position as coupling and not too steep, then most likely as a joint cross coupling can quickly wear out or break when you menggeber in bad terrain. To modify sedan / minivan became flat by reducing the screw per slug or a leaf in the pres flat or sometimes the curve becomes negative. These tweaks should not be imitated, because the number of conch Per reduced ulirnya will lose flexibility in reducing shocks. So is a leaf will be reduced elasticity and becomes hard suspension kickback effect. In the case of modifications, you can choose your own modifications or seek modifications to the car repair shop. If you choose a repair shop, note well the car modification services. How is the performance & their experience in car repair, body, and so on. Good luck.
