Suspension System Components

Suspension

system

is the term given to the

system

of springs, shock absorbers, and linkages that connects a vehicle to its wheels and allows relative movement between the two. The

suspension

system separates the wheel axle assembly from the body. A vehicle needs a

compress and expand when the wheel hits bumps or holes in the road. This allows the wheel to move up and down without moving the vehicle body mounts. vehicle weight provides a smooth ride allows for quick cornering without extreme body roll keeps the tires in firm contact with the road surface allows the front wheels to turn left or right for turning isolates the body from Road impacts and vibrations prevent successful ducking by tilting the body down the rear end when accelerating or heavily loaded prevents the body from leaning excessively downward when braking Suspension system includes steering knuckle control arm ball joint suspension springs stabilizer bar and shock absorbers the shaker knuckle is the part that contains the hub or axle of the wheel and is attached to the suspension and steering components the wheel hub and bearing assembly is mounted on the steering knuckle the Steering knuckle is mounted with a tie rod to the lower steering arm, brake caliper and strut control arm is a movable lever that attaches the steering knuckle to the body or frame of the vehicle.

Vehicles with short and long front arm. Suspensions have four control arms, two upper and two lower, while most strut-equipped vehicles have only two lower control arms in the front suspension. The front suspension ball joint is the part of the chassis that connects the steering knuckle to the control arm. The ball joint design of the joint allows it to rotate so the knuckles can pivot as the wheels are steered and allows it to arch so the knuckles can follow the vertical movements of the suspension as it reacts to changes in the road surface. road. Vehicles with short- and long-arm front suspensions have four ball joints, two upper and two lower.

Most strut-equipped vehicles have only two lower joints in the front suspension. The vehicle body is supported by suspension springs that are located between body and wheel axles there are four main types of springs in common use coil spring leaf spring torsion bar and rubber spring A coil spring is simply a spiral of strong steel rod that is stretched or compressed by the vertical movement of the wheels. Coil springs are the most common springs used in the front and rear of passenger cars. Coil springs absorb the force of impact by rotating the blade. The spring is one of the oldest forms of spring.

It is generally used in rear-wheel drive vehicles due to its simplicity. They are normally mounted longitudinally. Leaf springs are constructed from one or more long, narrow strips of spring steel. These metal strips called leaves are assembled with plastic or synthetic rubber insulators between the leaves that allow freedom of movement during the operation of the spring without generating wear or noise. The longest leaf, called the main leaf, is rolled at both ends to form eyes. These eyes are used to mount the spring to the vehicle frame. The blades are held together by a center bolt that passes through a hole in the center of each blade.

Rebound clips are formed at intervals around the leaves which prevent excessive flexing of the main leaf during rebound and also keep the leaves aligned at the front end of a leaf spring. The leaf spring is mounted on a hanger with a bolt and bushings. rubber directly attached to the frame. The rear end of the leaf spring is attached to the frame with movable mounting brackets called shackles. The leaf spring is also used to locate the shaft in the spring. The axle is then attached to the spring using U-bolts that wrap around the axle housing and through a spring plate under the spring torsion bar is a straight spring steel rod with knurled ends. or squares, one end of the bar is attached to the frame and the other end is connected to the lower control arm.

The torsion bar rotates around its center as the control arm deflects. Non-metallic materials such as rubber can provide the mainspring action, but are more commonly used as stops to limit extreme suspension movement. The bumpers may also be shaped to provide an auxiliary spring function in light vehicle applications. Bumpers can help cushion the suspension and prevent it from bottoming out. Stoppers are made in a few different designs so they can be mounted in different locations. Some are positioned in line with the piston rods. Other shock absorbers mount between the frame and the axle and absorb the impact before the axle has a chance to hit the frame.

The stabilizer bar is also called the stabilizer bar or the stabilizer bar. The stabilizer bar connects the lower control arms on both sides of the vehicle. The stabilizer bar works like a spring. when the car leans to one side if one wheel moves up or down relative to the other wheel the bar rotates as it tries to move the other wheel along with it the energy of the road impact caused the spring oscillate, these oscillations are restricted to a reasonable level by shock absorber there are three types of shock absorbers coil shock absorber and strut shock absorber are conventional telescopic shock absorbers that are used in all conventional suspension systems to cushion and control the movement of the vehicle springs one end one is connected to the body or frame and the other is connected Shock absorbers connected to the axle or control arm work together with springs to reduce the impact of bumps and bumps.

There are different types of shock absorbers, but they all use a piston that slides in an oil-filled cylinder. A monotube shock absorber has a single piston and rod assembly. in a damping case where both compression and rebound occur, it also has a free piston that completely separates the oil chamber from the gas chamber, the oil flows through a valve in the piston and the monotube has a volume of gas representing any volume. oil change twin tubes have an inner cylinder that moves up and down and an outer cylinder that serves as a hydraulic reserve this design allows for an increase in suspension stroke which provides better ride quality and handling a valve in The bottom of the shock absorber allows oil to flow into the reservoir as the piston moves up and down.

A coil shock absorber is a suspension device that consists of a shock absorber with a coil spring surrounding it. There are two types of coilover shock absorbers, full coilover shock absorbers and sliding coilover shock absorbers. Shocks are combined with a factory shock, while with slide shocks the shocks and springs are purchased separately and then assembled. The shock absorber is found on many vehicles, is used in double wishbone suspension systems and is often a component of Macpherson Struts. A strut is a structural part of the vehicle's suspension system and is mounted to the chassis at the top and descends to through a strut assembly which is formed by the strut stop or spring seat of the starter spring and mounts to the bottom of the strut.

It is usually attached to the steering knuckle and the top of the strut is connected to the vehicle body via an upper strut mount.
