Automotive Parts:Shock Absorbers

Functions and Roles

The shock absorber is installed between the car body and the tire, along with a spring. Elasticity of a spring damp shocks from road surface, however,it causes vehicle to vibrate due to its resilience characteristics. The part serves to damp shocks is referred to as a"shock absorber", and viscous resistance force is referred to as "damping force".

Shock absorbers are a critical product that determines an automobile's character, not only by improving ride quality but also by functioning to control the attitude and stability of the vehicle.


Forms of Suspensions and Types of Shock Absorbers

Double-wishboneMore Details

Conventional

Conventional

Double-tubed construction filled wish low pressure nitrogen gas. This type of shock absorber is supple and provides stable riding comfort.

Pressurized isolation

Pressurized isolation

Single-tubed construction filled with separate by free piston gas chamber filled with nitrogen gas. It provides a superb response as well as helps to reduce the weight of the car.

StrutMore Details

Conventional

Conventional

Double-tubed shock absorber with a function as part of the surpport structure of the suspension. Like the double wishbone type, it is a shock absorber filled with low-pressure nitrogen gas that is supple and provides stable riding comfort.

 
High rigidity inverted type

High rigidity inverted type

Structurally, this is a single-tube type placed upside down. In case of structs bears a heavy load from the vehicle body, however, this type of shock absorbers with large-diameter pipe provide sufficient rigidity.

 

Separately mounted spring (rigid axle, etc.)

Separately mounted spring (rigid axle, etc.)

Unit damper

Because the spring is mounted separately, this type features a simple structure comprised of a damping mechanism only.



SHOWA's Approach

SHOWA develops lightweight dampers using high-tension materials to improve ride quality and fuel performance. For further comfort improvements, we also develop oil seals that control resistance during damper operation. Based on the functional integration of advanced performance of each component part, SHOWA develops suspension modules for high-added value.
