Steering gear assembly.
The steering machine assembly includes the steering machine, the steering machine pull rod, the outer ball head of the steering rod, and the dust jacket of the pulling rod. The steering assembly is the steering device, also known as the steering machine, direction machine. It is the most important part of the automobile steering system. Its function is to increase the force transmitted by the steering disk to the steering transmission mechanism and change the direction of force transmission.
The classification of steering machines is as follows:
1. The mechanical steering gear is a mechanism that changes the rotation of the steering disc into the swing of the steering rocker arm and amplifies the torque according to a certain transmission ratio;
2, according to the different transmission mode, steering gear rack type, worm crank finger pin type, cycle ball - rack tooth fan type, cycle ball crank finger pin type, worm roller type and other structural forms;
3, according to whether there is a power device, the steering device is divided into mechanical (no power) and power (with power) two kinds.
The steering gear is an important assembly in the steering system, and its function mainly has three aspects. One is to increase the torque from the steering wheel so that it is large enough to overcome the steering resistance moment between the steering wheel and the road surface; The second is to reduce the speed of the steering drive shaft, and make the steering rocker arm shaft rotate, drive the swing of the rocker arm to obtain the required displacement at its end, or convert the rotation of the driving gear connected with the steering drive shaft into the linear movement of the rack and pinion to obtain the required displacement; The third is to coordinate the rotation direction of the steering wheel with the rotation direction of the steering wheel by selecting the screw direction of the screw on the different screw (snail) rod.
steering assembly failure can cause a variety of problems, including but not limited to:
vehicle deviation : even under normal tire pressure and smooth road conditions, the vehicle can still run off, usually because of a problem with the steering engine.
Abnormal noise : An abnormal noise or "clattering" sound while turning or turning on the spot is usually caused by faulty steering or tires.
steering wheel return difficulty : when the vehicle steering wheel return speed is too slow or can not automatically return, indicating that the steering machine of the car is damaged.
steering difficulties : If you feel the steering wheel become heavy while driving, especially at low speeds, this may be a signal of insufficient lubrication within the steering assembly or a worn component.
unstable steering : During driving, if the steering wheel wobbles or the direction of the vehicle is unstable, it may be due to damage to the gear or bearing inside the steering machine assembly.
Abnormal sound : Unusual noises heard during steering, such as crunching, clicking, or rubbing, usually indicate the presence of worn or loose parts inside the steering assembly.
oil leakage : Oil leakage in the steering assembly is a clear sign of failure. Oil leaks can be caused by aging or damaged seals.
oversteering or understeering : When steering, if you feel the abnormal strength of the steering disk, or over-steering or under-steering, it may be the mechanical parts inside the steering machine assembly are out of whack or damaged.
These problems can occur for a variety of reasons, including but not limited to steering engine failure, booster pump failure, return oil filter blockage, seal failure, limit valve failure, component failure, universal joint failure, flat bearing failure, protective sheath failure and safety valve failure . For these problems, it is recommended to seek professional vehicle maintenance services as soon as possible to ensure driving safety and vehicle performance.
