What Components Make Up a Shock Absorber Assembly?
Shock absorber assemblies are a common component of suspension systems, and can be used for a variety of purposes, including heavy duty applications, industrial machinery, and off-road racing vehicles. Typically, a shock absorber assembly consists of two components: a body, and a pressurized-gas cushioning means. The body acts as the main body of the assembly and is generally cylindrical in shape.
The pressurized-gas cushioning means is made up of a structure defining a first cavity for storing fluid under pressure. A piston is attached to the end of a piston rod, which extends in one direction. An oil seal prevents dust from entering the tube. During operation, the piston is positioned inside the cylinder, and receives resistance from the oil in the pressure tube. This allows the fluid to flow through the valves, which are typically positioned at predetermined controlled flow rates.
Another important component of shock absorber assemblies is the spring. Spring assemblies can be manufactured in different sizes, and in many cases, they are attached to the lower end of the assembly. For example, the spring may be attached to a mounting unit on the outside of the piston, or it may be incorporated into the vehicle. Regardless of the type of spring, the spring supports the weight of the vehicle and provides stability during movement.
Other components of shock absorber assemblies include the steering knuckle, which may be fixed to the lower end of the assembly. The shock absorber also has a hole for the placement of a locking pin, which is designed to secure the shock absorber assembly to the steering knuckle.
The strut assembly is another element of the shock absorber assembly. Strut assemblies are generally comprised of two primary elements: an upper spring mounting unit, and a lower spring mounting unit. In a typical shock absorber assembly, the upper spring mounting unit attaches to the end of the piston shaft, and the lower spring mounting unit attaches to the steering knuckle.
Additionally, spacers can be inserted around the upper and lower spring seats and/or the shock absorber. Spacers may be provided in the form of discs, washers, or shims. When installed, these spacers are arranged to create a distance between the lower spring seat plate and the lower spring seat mount.
Alternatively, the lower spring seat mount can be placed in a position that will lower the ride height of the vehicle. Depending on the type of vehicle, the spring and the spring seat plate may be located at various points along the lower end of the shock absorber assembly.
These embodiments of the present invention provide a variety of advantages over previous shock and strut assemblies. Unlike the prior art, the present invention provides a strut and shock assembly that does not require a large amount of modification. Some components can be left unmodified, so that the assembly can be easily repaired if the original equipment is damaged or worn. This can save the cost of replacement parts.
