1.在一定的载荷和行驶条件下,叉车的轮胎有一个适宜的轮胎气压,当轮胎气压低于标准值行驶时,轮胎径向变形增大,两侧产生过度挠曲,以致胎冠两侧接地,胎侧内壁受压,胎侧外壁受拉,胎体内帘线产生较大的变形和交变应力。周期性的压缩变形,会回速帘线的疲劳损坏,使轮胎的帘布层和轮胎与地面之间相对滑移增大,摩擦产生的热量增多,轮胎温度急剧上升,使橡胶的抗拉强度降低,帘线松
1. Under certain load and driving conditions, the forklift truck tires have a suitable tire pressure, when the tire pressure is lower than the standard value, the radial deformation of the tire increases, resulting in excessive deflection on both sides, so that both sides of the crown Grounding, sidewall compression, sidewall tension of the sidewall, the carcass cord has a greater deformation and alternating stress. Periodic compression deformation, will be back to the cord fatigue damage, the tire plies and tires and the relative increase between the slip, heat generated by friction increased, the tire temperature rose sharply, so that the rubber tensile strength decreased , Cord loose
