Jettower's mechanical steering gear is equipped with a rack and pinion structure, mainly assembled in 2005 before the Jetta taxi, its main feature is the structure is relatively simple, more flexible operation, leather and durable. If the maintenance used properly, in the taxi can be used 40-50 million km, and some even with the car until the vehicle scrapped.
    In the use and routine maintenance, we should note the following points, to extend the life of the direction of the machine:
    1. In the pavement uneven road driving, slow down, reducing the load on the steering machine.
    2. Always check the protective cover on both sides of the direction machine and the protective cover of the upper part of the direction machine and the universal cross shaft. The damage to the sheath is the most important factor leading to early wear and damage to the machine. After the sheath is damaged, the water and dust will penetrate into the steering machine through the breakage, destroying the grease film of the rack and pinion, causing the inside of the steering machine to rust, abnormal wear and so on. If the internal water and sand are not dealt with immediately, In the short term will cause the direction of the machine scrapped. So at least once a month to check the state of dust jacket, such as the sheath can be found to be damaged immediately replaced, and in the replacement before the direction of the machine to do a comprehensive inspection and maintenance.
    3. In the four rounds of positioning to adjust the front beam, change the steering rod, the special attention to the protective cover can not be distorted, the assembly is not in place and so on, otherwise it will cause damage to the jacket.
    4. As the use of grease will gradually become dirty, deterioration, so that the ability to reduce lubrication; at the same time wear the material will gradually increase, abrasive wear will become increasingly heavy, so that the direction of wear and tear increased. Each about 100,000 km or so to do a comprehensive maintenance of the direction of maintenance, a comprehensive clean, re-filling grease.
    5. The use of the direction of the machine is very bad, bear the load, you must use a dedicated grease, ordinary grease can not meet the requirements.
    6. The direction of the machine in the use of the gap will gradually increase, if the steering wheel left and right empty stroke more than 15 degrees, the direction of the machine must be checked, such as gear rack abnormal wear and tear, must change the direction of machine assembly; if no abnormal wear, Only the gap is too large, can be adjusted. In the adjustment to the service station by the training of professionals to adjust to ensure that the steering wheel to the left and right hit the limit position, and the strength of uniform, flexible rotation.
    7. Do not arbitrarily in the equipment, low level of technology at the roadside shop for the maintenance and maintenance of the direction. Directional machine such as improper adjustment, will cause stuck, endanger traffic and personal safety.
