Abstract

The invention discloses a low-rigidity quick-limiting rear shock-insulation buffer block for an automobile. The low-rigidity quick-limiting rear shock-insulation buffer block consists of a limiting framework (1) and vulcanized rubber (2). The limiting framework (1) comprises an inverted T-shaped cylinder horizontal part (11), an inverted T-shaped cylinder vertical part (12), a large chamfer (13),a small chamfer (14), a fillet structure A (15) and a fillet structure B (16), and the vulcanized rubber (2) comprises an inverted boss (21), a small circular boss (22), a U-shaped groove (23), a stepped wave-shaped structure (24), a thread hole (25), a combined arc (26) and vulcanized rubber (2) of other cylinder parts. When the automobile is impacted, automobile components such as a spring can be quickly limited and protected, so that the automobile components such as the spring are not impacted by hard collision, and impact damage is avoided.

Description

technical field [0001] The invention relates to the field of automobile limit buffer components, in particular to a limit buffer block fixed inside a rear frame spring. Background technique [0002] In recent years, with the rapid development of new energy vehicles, people have paid more and more attention to the performance requirements of key components of the vehicle. Most of the traditional limit blocks are mainly made of polyurethane. The main feature of polyurethane is that the product is foamed, and the initial stiffness is very small. After subsequent compression to the limit, the stiffness will increase instantly, but the product is not durable under heavy load. The rubber has short linearity, limited compression stroke and good durability. In order to integrate the market environment and solve the stiffness and durability matching in the early stage, a new limit block and or buffer block structure is required to meet the product use and market environment.
