Torsion beam limit block structure and limit system

Abstract

The invention discloses a torsion beam limiting block structure, which comprises: a non-metallic base, an annular installation part is arranged on the upper end, an installation groove is arranged on the inner peripheral side wall of the installation part, and an outer peripheral edge of the lower end of the installation part is provided with There are a plurality of outer vertical bars distributed along the circumferential direction, and the outer vertical bars extend downward to the bottom of the non-metallic base along the axial direction of the non-metallic base, and pass between two adjacent outer vertical bars The outer circumference reinforcing rib extending along the circumferential direction is connected, the bottom of the non-metallic base is installed on the torsion beam, and the limit block body is installed in the installation groove, which is used to limit the upper stroke of the torsion beam. This structure can effectively Avoid the risk of abnormal sound of the whole vehicle and improve the driving experience of users; the invention also discloses a limit system, which includes the above-mentioned torsion beam limit block structure installed on the torsion beam and the shock absorber limit block installed on the rear suspension. The block can meet the limit requirements of cars or electric vehicles with large axle loads.

Description

technical field

[0001] The invention relates to the technical field of automobile suspension, in particular to a torsion beam limiting block structure and a limiting system. Background technique

[0002] With the rapid development of my country's automobile market, the penetration rate of automobiles is getting higher and higher, and users' awareness of automobile safety is getting deeper and deeper, and they are paying more and more attention to the safety of automobiles. The limit block is an important part of the suspension system of the car, which directly determines the suspension travel, and affects the vehicle handling stability and ride comfort. Therefore, in addition to the spring performance of the shock absorber, the reliability of the suspension limit block is also more and more valued by users. Various types of suspension limit blocks came into being.

[0003] The limit blocks of the torsion beam suspension are usually assembled on the oil storage tank of the ...

Examples

Embodiment 1

[0039] Example 1, see figure 1 , image 3 As shown, the embodiment of the present invention discloses a torsion beam limiting block structure, which includes:

[0040] The plastic base is provided with a ring-shaped installation part on the upper end, and the inner peripheral side wall of the installation part is provided with installation grooves, and the outer peripheral edge of the lower end of the installation part is provided with twelve outer vertical bars 3 evenly distributed along the circumferential direction, it can be understood that What is more, the quantity of the outer vertical bars 3 can be set according to the required strength and space of the outer vertical bars 3, subject to the actual demand. Each outer vertical bar 3 extends axially downward to the bottom of the plastic base along the axial direction of the plastic base, and the middle parts of two adjacent outer vertical bars 3 pass through the outer circumferential reinforcing rib 5 extending in the ci...

Embodiment 2

[0043] Embodiment 2, continue to refer to figure 1 , on the basis of Embodiment 1, the inner peripheral edge of the lower end of the installation part is also provided with twelve inner vertical bars evenly distributed along the circumferential direction, and the connection line between each inner vertical bar and the outer vertical bar 3 at the corresponding position Falling in the radial direction of the plastic base, the inner vertical bars extend axially downward to the inner peripheral edge of the bottom along the axial direction of the plastic base, and the middle parts of two adjacent inner vertical bars are passed through the Rib connection on the inner circumference.

[0044] Moreover, the connecting point between the outer vertical bar 3 and the outer circumferential reinforcing rib 5 and the connecting point between the inner vertical bar and the inner circumferential reinforcing rib at the corresponding position pass through a radial direction extending radially al...

Embodiment 3

[0045] Embodiment 3, refer to figure 1 , figure 2 , which, on the basis of Example 2, also includes

[0046] The central hole of the limiting block body is a through hole extending along the centerline of the limiting block body 1, the top diameter of the central hole of the limiting block body is smaller than the bottom diameter of the central hole of the limiting block body, and an assembly The hole is used to pass through the fixed tool, and four buckles 2 are evenly distributed in the circumferential direction of the installation groove, which are used to clamp the limit block body 1 installed in the installation groove.

[0047] The first accommodating space 8 is surrounded by the upper section 4 of the inner vertical bar above the inner circumferential reinforcing rib,

[0048] The second accommodating space 12 is surrounded by the lower section 6 of the inner vertical bar located below the inner circumferential reinforcing rib, and the outer diameter of the upper sec...
