What is the role of power steering fluid?
The role of power steering fluid is not just to provide power. It plays multiple roles in the hydraulic power steering system, including the following aspects:
1. Pressure transmission: The power steering fluid is pressurized by the power steering pump and transmitted to the steering rack or gearbox to provide hydraulic assistance for the rotation of the steering wheel. When the driver turns the steering wheel, the hydraulic fluid helps push the steering mechanism, making steering operations easier.
2. Lubrication: Hydraulic fluid also acts as a lubricant, which can reduce friction between metal parts inside the steering system and prevent wear and overheating. If the fluid is insufficient or completely exhausted, the lubrication effect of the steering system will be greatly weakened, resulting in excessive friction of mechanical parts and increased losses.
3. Cooling: Hydraulic fluid helps absorb and disperse heat caused by hydraulic pressure, thereby preventing the steering system from overheating. If the power steering fluid is exhausted, overheating may cause additional damage to components such as pumps, racks, and gearboxes.
Therefore, power steering fluid plays a vital role in keeping the hydraulic system functioning properly and extending the life of the steering system.
How does the hydraulic power steering system work?
The core components of the hydraulic power steering system include the steering pump, steering rack, steering fluid storage tank, and high-pressure hose. Its working principle can be simply summarized as follows:
1. When the engine is running, the power steering pump starts and pressurizes the power steering fluid.
2. These pressurized fluids are transmitted to the steering rack through the hose, pushing the hydraulic piston in the rack to provide steering assistance.
3. The force input by the driver through the steering wheel works together with the power assist provided by the hydraulic system to control the steering direction and angle of the front wheels.
4. The hydraulic system also acts as a lubricant and cooler to prevent excessive wear or overheating of the steering mechanism.
Under normal circumstances, the hydraulic system maintains pressure and lubrication through circulating fluid. But if the power steering fluid is exhausted, the power assist function of the entire system will be damaged, and the operation of the steering rack will become extremely difficult.
What effect does the exhaustion of power steering fluid have on the steering system?
When the power steering fluid is exhausted, the driver will immediately feel that the steering system has become heavy, especially when driving at low speeds or parking. This steering difficulty is particularly obvious. However, this is not just a matter of driving experience, but also about the mechanical health of the steering system.
Loss of steering assist
When the power steering fluid is exhausted, the steering system loses hydraulic assist, and the driver needs to rely on manual force to turn the steering wheel. This will cause the driver to feel that the steering wheel is abnormally heavy and the steering process is more laborious, especially at low speeds or parking. This effect is particularly significant. In this case, the steering response speed of the vehicle will be reduced, increasing the risk of driving safety.
Loss of Lubrication
Power steering fluid is not only responsible for transmitting pressure, but also lubricates the steering rack and gearbox. When the fluid is exhausted, the friction between metal parts increases, which directly affects the life of the steering system. In the absence of lubrication, the longer the metal is in direct contact with the metal, the faster the parts will wear. This excessive wear can cause the steering rack and other key components to fail.
Overheating problems
When the power steering fluid is insufficient, the steering pump and other components are not protected by the cooling of the hydraulic oil. This can cause overheating, especially during long-term operation or in high-temperature environments. The steering pump and rack are prone to mechanical failure in high-temperature environments, and may even cause permanent damage.
What damage does depleted power steering fluid cause to the steering rack?
The damage caused by depleted power steering fluid to the steering rack cannot be ignored. Here are some common damages that depleted power steering fluid may cause to the steering rack:
Rack wear
The operation between the rack and the pinion depends on adequate lubrication. When the power steering fluid is exhausted, this lubrication function fails, resulting in excessive friction between metal parts and abnormal wear. The gear portion of the rack will be damaged due to direct contact, and eventually the steering rack will fail.
Deformed rack
If you continue to drive for a long time without hydraulic power assistance, the rack may be subjected to excessive physical stress, especially when the driver needs to apply more force when turning the steering wheel. This excessive stress may cause the rack to deform and even affect the accuracy of the entire steering system, causing the vehicle to steer inaccurately or lose control.
Damage to other parts of the system
The exhaustion of power steering fluid will not only directly damage the steering rack, but also other parts of the entire hydraulic system. The steering pump continues to work without hydraulic fluid, which will generate greater friction and heat, eventually leading to premature failure of the pump. The hoses and seals connecting the rack to the pump may also age and damage without fluid flow.
Damage to the pump
The power steering pump is the core power source of the hydraulic system. If the hydraulic fluid is exhausted, the pump will lose the fluid that provides pressure and continue to run dry. This dry operation will cause excessive wear of the mechanical parts of the pump, eventually causing the pump to fail. This fault will not only cause steering failure, but also accelerate the wear of other related parts.
What are the warning signs of power steering fluid exhaustion?
It is crucial to detect the warning signs of insufficient power steering fluid in time to prevent system damage. Here are some common warning signs:
1. The steering wheel becomes heavier: When the power steering fluid is low, the driver will first feel that the steering wheel is heavier than usual, especially when driving at low speeds.
2. Steering abnormal noise: If the fluid is low, the steering system may squeak or click, usually heard when turning the steering wheel.
3. Fluid level warning light: Modern vehicles are usually equipped with a fluid level sensor, and when the power steering fluid level drops to a dangerous level, the warning light on the dashboard will light up.
4. Leakage traces: Hydraulic fluid leakage may leave oil stains under the vehicle or near the wheels. Checking whether there are oil stains where the vehicle is parked can help detect problems in time.
What are some ways to prevent power steering fluid from running out?
To prevent damage to the steering system caused by power steering fluid exhaustion, car owners should take the following measures:
1. Check the fluid level regularly: The power steering fluid level should be checked regularly, especially before the vehicle is used frequently or long-distance driving. If the fluid level is found to be below the specified range, add hydraulic fluid in time.
2. Pay attention to abnormal signals: If you find that the steering system becomes unusually heavy or hear unusual noises while driving, you should stop and check as soon as possible to avoid further damage caused by the continued operation of the hydraulic system.
3. Regular maintenance: The hoses, pumps and seals of the power steering system should be regularly maintained and replaced to ensure that the system is in good condition and avoid fluid leakage and depletion caused by aging of components.
