4.12.1 轮胎的使用
Use Of tyre
轮胎是拖拉机的主要易损件，必须注意轮胎的使用和维护，以尽可能延长其使用寿命。
Tyre is the consumable of tractor. More attention shall be paid to usage and maintenance to prolong its service
life.
轮胎都有规定的负荷值，超负荷会使轮胎过分变形，胎侧过度弯曲而易断裂，胎体织物以及缓冲层也易
脱胶，织物层松散直至轮胎破裂，特别在路面不平或受障碍物冲击时，更容易破裂。
The tyre has specified loading value. If overloaded, the tyre is deformed excessively; the side is bent
excessively, which is easy to break off. Adhesive for the woven fabric in the tyre and buffer layer is easy to
come apart. The woven fabric layer is loose until the tyre is broken. Especially on the uneven or affected by
the impact of obstructions, it is much easier to break.
轮胎充气压力必须符合规定，过高过低，都会影响使用寿命。气压过低易使轮胎过分变形，加速胎面磨
损，甚至使内外胎迅速碾坏，气门嘴被切掉；同时增加行驶阻力。前轮胎气压过低，操纵费力；过高，
会使胎体织物过分拉伸而断裂，并加速胎面磨损，机身振动增大。田间作业时轮胎气压宜适当低一些；
长期公路运输则适当高些。轮胎气压应在常温下用气压表检查，以免作业后轮胎发热而测量不准。驾驶
操作不当也会使轮胎早期磨损或损坏。在行车中应避免高速越过障碍物、猛刹车或急转弯。在碎石路面
行车时应尽量避免轮胎滑转。
Inflation pressure of the tyre shall comply with the provisions. Both too hight or too low will influence its
service life. It is apt to make the tyre distortion too much, hasten the tread wear, or even make the tubes and
tyres crush rapidly and inflating valve cut off because of too low air pressure; at the same time, increase the
running resistance. If the air pressure of front wheel tyre is too low, the operation will be arduous; if too high,
the tyre fabric will be excessively drawn and broken. and the tyre wear will increase and the tractor vibration
will increase. The tyre pressure for working in the field should be suitably low, and the tyre pressure for
long-term transportation on road should be suitably high. Pressure in the tyre shall be measured by pressure
gage in ambient temperature. The measurement after the operation is not proper because of tyre heating.
Improper operation for driving can wear or damage the tyres early During running, the tractor should avoid
going over obstacle at high speed, emergency stop or steering. When running on broken-stone road, the tyre
slip should be avoided as little as possible.
使用中勿使轮胎沾上油、酸或碱等化学腐蚀品，尽量避免在烈日下曝晒，以免橡胶老化变质。前轮定位
拖拉机停放在水平的地面上，使前轮处于直线行驶位置，如
图所示，通过调整横拉杆 2 的长度使 A-B=前束值。注意前
束检查调整完后，应将横拉杆两端锁紧螺母 l 紧固。
Place the tractor on the horizontal ground, make the front
wheel in the position of straight running, as shown in Figure
2-38. Adjusting the length of the tie rod 2 to make A-B=value
of toe-in. After checking and adjusting the toe-in, you shall
tighten the nuts 1 on the ends of the tie rod.
