The driver needs to exert more force when steering, which is especially dangerous for inexperienced drivers. In an emergency, the lack of steering power may cause the vehicle to fail to avoid obstacles in time or make correct steering operations, causing accidents.

The main function of the power steering pump is to provide hydraulic pressure and is the "heart" of the system. The power steering rack is the actuator, which converts hydraulic pressure into mechanical movement and is the "hands and feet" of the system. The pump provides power support for the rack, while the rack converts this power into actual steering effect.

In general, the service life of the hydraulic power steering rack is between 120,000 and 150,000 kilometers. However, this value is not absolute, because different use conditions will have different effects on its life.

New energy vehicles, especially pure electric vehicles, usually choose electric power steering systems when designing their power steering systems. The main reasons are as follows: Energy matching of electric power steering systems Efficient energy use Simple structure and high reliability

Hydraulic power steering rack (HPS Rack) is the most common type of steering system in traditional fuel vehicles. Its core is to provide steering assistance through hydraulic pressure. This rack usually works with a hydraulic pump, oil pipe, valve and hydraulic oil tank.

In hydraulic steering racks, the modulus of the rack and pinion is usually selected within a certain range to balance accuracy, strength and manufacturing cost. Generally speaking, rack and pinion with a modulus between 2 and 4 mm are more common.

Generally speaking, the price of the seal itself is not high, usually between $20 and $50. However, since replacing the seal requires disassembling the steering rack, the labor cost is higher, usually between $100 and $300. Therefore, the overall cost may be between $120 and $350.

The primary function of the power steering rack is to transmit the steering force applied by the driver through the steering wheel to the wheels. This transmission process seems simple, but it actually involves complex mechanical and hydraulic conversions.

Steering fluid is required for Hydraulic Power Steering (HPS) and Electronic Hydraulic Power Steering (EHPS). This is because these systems rely on hydraulic fluid to generate pressure to assist in steering operations. In Electronic Power Steering (EPS), steering fluid is not required.

Manual steering racks are significantly different in structure from hydraulic steering racks, so direct replacement is not always possible. Installing a manual steering rack may require modifications to the vehicle's suspension system and steering column to ensure compatibility between the two.
