Why is power steering one of the most labor-saving devices in a car

The "Power Steering Oil Seal" is applied to the power steering system of automobiles, which can prevent dust, sediment and water from entering the steering system, and at the same time keep the gears lubricated to ensure the normal operation of the power steering system.Any Size Oil Seal for Power Steering Rack High Pressure Rack Power Seal.

 

 

At its most basic, power steering is a system that reduces the effort required of the driver to turn the steering wheel. Without power assist, the steering of most vehicles would be extremely heavy, particularly during low-speed maneuvers such as pulling into a parking spot, turning a 90-degree corner in the city, or maneuvering in a crowded gas station.

 

The power steering oil seal is used in the automobile power steering system, and is a kind of automobile steering oil seal.  Its function is to prevent dust, sand and water from entering the steering system, keep the gears lubricated, and ensure the normal operation of the power steering system.
 

Features
1.The inner diameter retaining ring design has strong compressive ability and is not easy to deform and fail.
2.The lip spiral design, to return the oil to the oil side, prevent oil leakage, reduce friction and temperature rise. The auxiliary lip can prevent the main lip from reversing.
3.Bonded rubber to metal design ensures hardness and ensures good sealing performance.

The "Power Steering Oil Seal" is applied to the power steering system of automobiles, which can prevent dust, sediment and water from entering the steering system, and at the same time keep the gears lubricated to ensure the normal operation of the power steering system. The inner diameter back support ring design enhances the pressure resistance of the oil seal. The oil return groove design on the lip part sends the sealing oil body back to the oil side without oil leakage, and can reduce friction and temperature rise.

Power steering oil seal type:
1. Recirculating ball power steering oil seal: 1) Input shaft oil seal; 2) Rocker shaft oil seal

2. Rack and pinion power steering oil seal: 1) Input shaft oil seal; 2) Pinion shaft oil seal; 3) Rack frame inner and outer oil seals;

3. Steering hydraulic cylinder oil seal;

4. Electro-hydraulic steering gear oil seal;

5. Steering booster pump oil seal.

Features of Power Steering Oil Seals：
There are two types of Power steering oil seal, one is a rotary seal installed on the steering shaft, and the other is a reciprocating seal installed on the power cylinder rack shaft.
NNK pinion shaft seals:
Rotary seal mounted on steering shaft to prevent leakage and maintain lubrication.
The bonded rubber-to-metal design ensures strength while providing an excellent seal.
The secondary lip prevents the primary lip from inverting.
NNK rack shaft seals:
Reciprocating seal mounted on the power cylinder rack shaft.
The composite design of the metal shell and the support ring ensures the sealing performance under high pressure.
Integrated support ring, with strong pressure resistance.
Hydrodynamic helix for reduced friction and heat generation and longer seal life.
Material: nitrile rubber/hydrogenated nitrile rubber

A rack and pinion steering system consists of a pinion (a circular gear) with a rack (a linear gear). The system works by converting a revolving motion into linear motion. Most cars, small trucks, and SUVs come equipped with a rack and pinion system, rather than the recirculating ball steering found in larger trucks, larger SUVs, and other heavy-duty vehicles.

Using rack and pinion steering, the rotation of the pinion causes the linear movement of the rack, so that the wheels of the vehicle turn left or right. Rack and pinion systems are common components on railways. Between the train tracks are racks of pinion gears connected to the locomotive and carriages that interact to help the train move on steep slopes.

Rack and pinion steering systems weigh less than circular ball gearboxes, which helps improve fuel consumption. Rack and pinion systems are lighter because they do not require the idler arm, Pitman arm, center link and tie rod sleeve found in traditional steering systems. The size and weight of the rack and pinion system makes it more suitable for front-wheel drive applications, as manufacturers can mount it next to the transverse drivetrain. It is easier for manufacturers to tailor rack and gear transmissions to suit specific wheelbases and handling packages.

Common Rack and Pinion Steering Problems

Because it's impossible to operate a car without steering, it's essential to be on the lookout for any problems so you can get them repaired as soon as possible. Common steering issues,include:

• A tight steering wheel: If it seems like your steering wheel is harder to turn, this could indicate a problem with the steering rack or inadequate pressure in the power steering system. This issue is usually solved by adding more power steering fluid.
• Power steering fluid leakage: If your car is leaking power steering fluid, you should have it repaired before it causes the gearbox to overheat or the gears to break.
• Grinding noises: A grinding noise usually indicates inadequate lubrication in the steering gearbox. The gearbox may need to be replaced.
• Burning oil: Power steering fluid has an odor similar to burning oil. If you notice this odor while driving, pull over as soon as it's safe. Your gearbox may be overheated and could catch on fire.

The rack and pinion steering system has led to more cost-effective car production, improved gas mileage, and easier vehicle handling. It is certainly a revolutionary advancement in the automotive industry.
