What Causes Hydraulic Power Steering to Become Heavier?
1 Answers
Hydraulic power steering becoming heavier is most commonly caused by dirty power steering fluid. Like other automotive fluids, power steering fluid needs to be replaced periodically. Another possible cause is low tire pressure, which can also make the steering wheel feel heavier. In severe cases, insufficient tire pressure may even lead to a tire blowout. Therefore, when the steering wheel becomes heavier, the first things to check are the tire pressure and power steering fluid. More information on hydraulic power steering is as follows: 1. Introduction: The vast majority of vehicle models use hydraulic power steering systems, which can be further divided into mechanical hydraulic steering and electro-hydraulic steering. Both work on a similar principle: a hydraulic pump (driven by the engine belt) provides oil pressure to push the piston, generating auxiliary force to move the steering linkage and assist in wheel turning. 2. Difference: The key difference lies in how the oil pressure pump is driven. Mechanical hydraulic power steering uses a hydraulic pump directly driven by the engine belt, while electro-hydraulic power steering uses an electric pump driven by an electric motor.
