Problems solved by technology

As the core component of the electronically controlled air suspension, the air spring has become the key to improving comfort. Although the air spring in common use can improve the comfort of the vehicle, it cannot be used as a structural part to transmit directional forces such as torsion and deflection. It needs to cooperate with other implementations. Accessories with torsion and deflection functions have the problems of large installation space and high cost

Embodiment 1

[0033] Embodiment 1: see figure 1 , image 3 , an air spring comprising:

[0034] upper cover 1;

[0035] The airbag 2 is arranged under the upper cover 1, and the top of the airbag 2 (ie, the upper buckle end 201) is connected to the upper cover 1 through the first snap ring 3; the inner wall of the airbag 2 is provided with a first restraining ring 401, which divides the airbag 2 Two sections, the exposed part of the airbag in the upper section adopts two layers of along-line cords 202, and the other parts of the airbag adopt cross cords 203;

[0036] The piston 5 is located below the air bag 2, forms a sealed container with the upper cover 1 and the air bag 2, and the outer edge of the top end of the piston 5 is connected with the air bag 2 through the second snap ring 6;

[0037] The base 7 is arranged below the piston 5, and the upper end of the base 7 is connected with the piston 5;

[0038] The bearing 8 is located between the base 7 and the piston 5, and is connect...

Embodiment 2

[0051] Embodiment 2: An air spring. The difference from Embodiment 1 is that in this embodiment, the airbag is made of nylon wire and rubber vulcanized at a high temperature of 160°C, so that the nylon wire and rubber have chemically reacted and fused together. The body, the three-layer along-line cord on the exposed part of the upper airbag is made by parallel and along-line technology.

[0052] The above-mentioned air spring in this embodiment is mainly equipped with passenger cars with multi-link independent suspension, such as: all Mercedes-Benz E-class series, BMW 3 series and 5 series, FAW-Volkswagen Audi A4L and A6L, Passat of Shanghai Volkswagen and many models. The above-mentioned multi-link independent suspension is a suspension with high popularity.

Embodiment 3

[0053] Embodiment 3: An air spring. The difference from Embodiment 1 is that in this embodiment, the airbag is made of nylon thread and rubber vulcanized at a high temperature of 180°C, so that the nylon thread and rubber have chemically reacted and fused together. Body, the two-layer along-line cord of the exposed part of the airbag in the upper section is made by parallel and along-line technology.

[0054] The above-mentioned air spring in this embodiment is mainly equipped with passenger cars with multi-link independent suspension, such as: all Mercedes-Benz E-class series, BMW 3 series and 5 series, FAW-Volkswagen Audi A4L and A6L, Passat of Shanghai Volkswagen and many models. The above-mentioned multi-link independent suspension is a suspension with high popularity.

Abstract

The invention relates to an air spring and a multi-connecting-rod independent suspension. The air spring comprises an upper cover; an airbag, arranged below the upper cover, and the top end of the airbag being connected with the upper cover through a first snap ring; a first restraint ring, arranged on the inner wall of the airbag and dividing the airbag into two sections, at least two layers of smooth cord threads being adopted for the exposed part of the upper-section airbag, and crossed cord threads being adopted for the other parts of the airbag; a piston, arranged below the airbag and forms a sealed container with the upper cover and the airbag, and the outer edge of the top end of the piston being connected with the airbag through a second snap ring; a base, arranged below the piston, and the upper end being connected with the piston; a bearing, arranged between the base and the piston and connected with the upper end of the base; and a restraining cover, arranged on the outer wall of the lower-section air bag and connected with the first restraining ring and the lower-section air bag into a whole. The air spring solves the problem that a traditional air spring cannot achieve torsion and deflection, and is small in installation space, low in cost and long in service life.

Description

technical field [0001] The invention belongs to the technical field of transportation and relates to an independent suspension for passenger cars, in particular to an air spring and a multi-link independent suspension. Background technique [0002] At present, the type of independent suspension for passenger vehicles mostly adopts the McPherson structure or the double-wishbone structure of the front suspension, and the multi-link structure of the rear suspension. Among the above-mentioned independent suspension types, the suspension that adopts the damping type is divided into two configurations: coil spring shock absorber and air spring shock absorber. The coil spring shock absorber has high stiffness and poor comfort, but has a long service life; the air spring shock absorber has nonlinear characteristics, a large load range, the stiffness changes with the load, the natural frequency is low, and the natural frequency is basically unchanged when the load changes, which can ...
