Type and Function of Car Suspension

Hasil gambar untuk suspensi pada mobil

Suspension is designed on your car that not only to reduce shocks, but also to improve the stability of your car, and increase the wheel traction to the road.

Suspension consists of spring, shock absorber, stabilizer, link stabilizer or active stabilizer. Suspensions are categorized in several  types such as free type, multilink, five links, machpherson, double wishbone, or torsion beam.

The type of suspension used in each vehicle depends on the class and its usage requirements of each vehicle. Follow the following reviews, to get to know the character and functionality of each suspension design.

Torque Beam

As in the small car segment, such as Honda Jazz, Suzuki Swift and Kia Rio, using torsion beam. The reason is because the factor to suppress the production price, easy to repair and proven in the class of cars has produced a fairly good quality control. Disadvantages of the torsion beam design, generally kick it feels a bit hard, especially when crossing a rather curly road surface.

Rigid Suspension

Rigid suspension

In the rigid type suspension type, the left and right wheels are connected to a single axle. The axle is connected to the body and the frame through the spring (leaf springs or coil spring). Rigid suspension is widely used in commercial  vehicles such as buses and trucks, alias because of its strong and simple design construction. Especially when carrying heavy loads and traversing unfavorable road surface conditions.

Independent Suspension

In the independent suspension design, the left and right wheels are not connected directly to a single axle. The effects of the concept of the structure can move freely without mutual influence, which can produce a fairly good degree of precision control, especially when crossing a bumpy road surface, because the type of suspension can adjust quickly to changes in wheel rotation and road contours. That can automatically further increase the traction of the wheels into the road. The advantages of this type of suspension can absorb vibration more optimally, and maximize the braking force, and maintain the geometric position between the body and the wheels.


This type of multi-link suspension is equipped with three or more arms. Metal construction connections from various locations are connected to various locations and adopted to manipulate the movement that occurs in your car body. Multilink suspension is considered very complex and for the tuning process required a computerized system that can display 3-dimensional images …

Toyota Hybrid System


Hybrid system is basically combines two propulsion of conventional engine and electric motor. How it works in turns and simultaneously makes  the engine as a generator.
At Toyota Hybrid System (THS) is known two systems namely Parallel and Series. Each shows the structure of the relationship between the engines with the electric motor used.

Hybrid system components in Toyota include:
One important component that serves to supply and store energy. Toyota has developed efficient and lightweight battery technology. This is achieved thanks to the use of nickel hydride material (Ni-MH).
The cooling system in the battery cell has also been optimized. The use of semiconductor technology also has an important role in the operation of hybrids. For that matter Toyota has improved battery efficiency by adopting silicon carbide (SiC).

Type of gasoline engine or gasoline used in Toyota hybrid technology claimed to be more energy efficient. Moreover, it can produce higher output than similar conventional machines.
Various developments to improve engine performance continue to be done to achieve a new mechanism that more fuel efficient with no maximum power.

Electric motor
This component is one of the main things in hybrid cars. Toyota uses an efficient electric motor, can produce strong torque up to the range of revolution (rpm) high. Its form is more compact, lightweight, efficient, and smooth.
The component uses electric current in a 3-phase system, capable of optimum control of magnetic rotation with magnetic rotor having an ideal structure of configuration V.

Power Control Unit (PCU)
This tool is to divide and distribute electric power generated by the engine to the drive train. The PCU consists of an inverter to convert DC current into AC provided by the battery to turn on the electric motor.
Instead, the inverter will also convert the AC generated by the electric motor and generator into DC to recharge the battery. Another element of this PCU is the boosting converter. Its function is to increase the normal voltage or power of 201.6 V at DC supply to 650 V for electric motors.
Then DC converter to reduce the voltage of 201.6 V supply from battery to 12 V voltage for the use of support systems and electronic devices such as ECU.

Power Split Device
The device adjusts the rotation of the shaft directly to the engine and connected to the electric motor.

Reduction Gear
Its function is to reduce …
