The GNA suspension is a McPherson strut with spring and damper combined into one unit. The lower part of this assembly is connected to the suspension arm. To ensure the possibility of turning the McPherson strut, its upper part is equipped with a bearing, which is the connecting link between the suspension strut and the body.
The GNA front suspension consists of the following parts:
- Rack McPherson.
- suspension arms.
- Strut braces.
- Wheel hubs.
- Bars of the stabilizer of cross stability.
1. The upper attachment points of the suspension to the body
2. Axis of rotation of wheels
3. Wheel centers
4. Spindles
5. Lower attachment points of the suspension to the body
- Racks of the stabilizer of cross-section stability.
GNB suspension uses HiPerStrut strut (High Performance Strut - high performance rack), consisting of a spring and a shock absorber combined into one unit. The strut and the lower suspension arm are connected by a fork, which is connected to the steering knuckle by means of a ball joint and a kingpin bushing.
The GNB front suspension consists of the following parts:
- Dual tubular CDC shock absorbers with coil springs.
- Forks.
- The upper ball bearings of the steering knuckles.
- Swivel fists.
- The kingpin bushings in the steering knuckles.
- Wheel hubs.
- Lower arms.
- Bars of the stabilizer of cross stability.
- Racks of the stabilizer of cross-section stability.
- Pivots.
The advantage of the GNB suspension over the GNA lies in the shorter spindle length, which provides:
- reduction of shaking on a flat road;
- less effort to turn the steered wheels;
- increased roll stability in corners;
- resistance to wheel imbalance.
In addition to providing increased ride and handling, the HiPerStrut suspension allows you to install larger diameter wheels on the car, as well as adjust the camber of the wheels through the fastening of the upper ball joints.
The front suspension performs two main tasks:
- Isolates the driver from uneven road surfaces.
- Determines the ride and handling characteristics of the vehicle.
The front suspension absorbs impact energy from rolling tires and distributes it to the suspension components. This process allows you to protect the passengers of the car from shaking associated with uneven road surfaces. The speed at which the suspension dissipates energy and the amount of energy absorbed are the main characteristics of the suspension that determine the smoothness of the car. Driving characteristics are structurally incorporated into the suspension and are not regulated. Ride characteristics are referred to in this manual to help you understand how the suspension functions. The suspension must provide vertical movement of the wheel assembly with the tire when the vehicle moves over uneven road surfaces while maintaining the horizontal position of the wheel relative to the road.
