Types of Volvo Power Steering

Volvo power steering is a vital component of every Volvo vehicle, making the steering wheel easy to turn. This system uses hydraulic or electric actuators to reduce the driver's effort in steering the vehicle. The type of power steering available in a Volvo vehicle includes the following.

• Volvo hydraulic power steering

  Many older Volvo models come with hydraulic power steering. This system uses hydraulic fluid to amplify the driver's steering effort. The hydraulic pump receives power from the engine via a belt. When the driver turns the steering wheel, the connected valves and pistons in the pump generate a flow of hydraulic fluid. This fluid activates the valves and pistons, providing a force that helps the driver steer the car. The main components of hydraulic power steering include hoses, valves, pistons, and the steering gear box. Although hydraulic power steering is not common in newer Volvo models, it is still available in some models.

• Electric power steering (EPS)

  Electric power steering (EPS) is the most common steering technology used in modern Volvo cars. This is because EPS is energy-efficient and requires less maintenance compared to other power steering systems. EPS uses an electric motor to assist the steering. Depending on the model, the motor is located on the steering column or the rack. EPS also has sensors that detect the driver's steering input. When the driver steers the wheel, the sensor detects the movement and sends a signal to the motor. The motor then provides the necessary assistance, making it easy to turn the steering wheel. Besides being maintenance-free, EPS allows for more precise control of the vehicle. Some advanced EPS systems in high-end Volvo models come with variable assistance. This means the EPS system adjusts the level of assistance based on the steering angle and the vehicle's speed.

• Volvo servo steering

  Volvo servo steering is a combination of hydraulic and electric power steering systems. This power steering system uses hydraulic fluid like the traditional hydraulic power steering. However, it also uses electric technology to enhance steering assistance. The electric motor in the servo steering system provides more assistance to the driver when steering the vehicle at low speeds. Conversely, the system reduces the electric assistance when the vehicle is moving at higher speeds. As a result, the vehicle's steering becomes more responsive and stable, improving overall handling. The servo steering system is ideal for heavy-duty and high-performance Volvo trucks and vehicles.
