汽车维修资料（Vehicle maintenance data） Steering system 1. what are the requirements for the steering gear in use? The function of the automobile steering device is to change the direction of the car and maintain the steady state of the car in order to adapt to the complex and changeable road and to change the direction of the car at any time. The technical condition of the automobile steering device has great influence on the handiness of drivers driving and the safety of driving. Therefore, requirements of steering device work must be reliable, the parts have sufficient strength, to ensure traffic safety requirements; flexible steering, in order to reduce the drivers labor; but also in the car turned around, the steering wheel should have correct movement, to ensure that the steering wheel rolling, and prevent slip drag. The load on the steering gear is great when the car is moving. On the one hand, the force from the driver on the steering wheel, on the other hand, is also affected by the impact of the road. So, with the use of time, steering parts due to friction between the moving parts, destroyed the original clearance; even cause deformation and mechanical damage, the deterioration of the technical condition of steering device. This will not only reduce the flexibility of steering control, increase the labor intensity of the driver, but also affect the driving safety, causing serious vehicle accidents. Therefore, in addition to the correct use of the steering gear, it should also do a good job of inspection and maintenance work, and find out the faults and eliminate them in time so that they can always maintain good technical condition. (1) check the technical condition of the steering gear regularly: The steering device is in use, the lubricating oil in the machine to reduce volatilization and leakage due to mechanical wear, the gap increases, the technical condition of the steering device is decreased, nip in the bud, to keep a good condition, should regularly che
