Problems solved by technology
When the semi-trailer is running, the adjustment rod 1` is affected by many factors such as tension, vehicle bumps, and body deformation, thereby changing the wheelbase, causing the wheelbase error to exceed a predetermined value. The phenomenon of semi-trailer running deviation, tire eccentric wear, and brake flicking has seriously affected the performance of the semi-trailer, and even caused safety accidents. Therefore, it is necessary to study the suspension system and application of this structure The suspension system of the semi-trailer is improved

Abstract
The invention relates to a suspension bracket of a semitrailer, which comprises an adjustable pull rod. The adjustable pull rod comprises an adjusting rod, two pull rod joints and two locking bolts; the two pull rod joints are connected by threads and are sleeved on two ends of the adjusting rod; the two locking bolts are used for locking one end of the adjusting rod together with the pull rod joints; the adjusting rod and the pull rod joints are provided with matched threads and are matched to adjust the whole length of the adjusting pull rod; each pull rod joint is provided with an opening and two elastic clamping pieces, wherein the opening longitudinally extends along the pull rod joint and is clamped in the two elastic clamping pieces, and the two elastic clamping pieces are convexly arranged from the outer surfaces to the outer side of the pull rod joint; each locking bolt transversely penetrates through the two elastic clamping pieces along the pull rod joints; and clamping and pulling devices which are used for limiting the adjusting rod to rotate relative to the pull rod joints are arranged at the joints of the adjusting rod and the pull rod joints. The wheel base of the semitrailer can not change under the action of external force when the semitrailer runs.
Description
technical field [0001] The invention relates to a semi-trailer component, especially related to the suspension system of the semi-trailer; [0002] The invention also relates to a semi-trailer using the suspension system. Background technique [0003] An ordinary semi-trailer includes a body, an axle and a suspension system. The axle and the suspension system are located at the bottom of the vehicle body. The axle is in the shape of a barbell. The system is located between the body and the axle to connect the axle and the body; when the body is dragged by an external force, the body drives the wheels at both ends of the axle to move through the suspension system. [0004] see figure 1 and figure 2 The suspension system of a common semi-trailer includes an adjustment rod 1` and a tie rod joint 2`, threads are provided at both ends of the adjustment rod 1`, the cross section of the adjustment rod joint 2` is inverted U-shaped, and its bottom is open. The opening is provid...
