Description

Technical Field

[0001] The utility model relates to the technical field of leaf springs, in particular to a leaf spring in an automobile steering system. Background Art

[0002] The leaf spring is made of multiple steel plates of unequal length and curvature. After installation, the two ends naturally bend upward. When the impact force of the road surface on the wheel is transmitted, the steel plate deforms, which plays a role in buffering and shock absorption. When arranged longitudinally, it also has the function of guiding and transmitting force. The existing patented leaf spring assembly, patent publication number CN104653681A includes a leaf-shaped member, and the leaf-shaped member has a first end and a second end on opposite sides of the center point. The leaf-shaped member is the only leaf-shaped member in the leaf spring assembly. The leaf spring assembly also includes a first buffer and a second buffer separated from the first buffer. The first buffer contacts the leaf-shaped member during the first displacement of the leaf spring assembly. The second buffer also contacts the leaf-shaped member during the first displacement of the leaf spring assembly.

[0003] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: although they can be cushioned by a buffer during use, they require steel pins to pass through multiple steel plates for anti-deviating fixation during use. However, after the pins are fixed to the inside of the steel plates, they need to be fixed by welding, which makes it inconvenient to disassemble them later during processing. Therefore, we propose a leaf spring in an automobile steering system to solve the above-mentioned problems. Utility Model Content
