Abstract

The utility model provides a novel double trailing-arm type air suspension structure which comprises a suspension guiding mechanism connected between the vertical beam of a car frame and an axle, an air spring, a shock absorber and a car frame bracket connected with the vertical beam of the car frame. The suspension guiding mechanism comprises a horizontal stabilizer rod with the function of a thrust rod, an upper thrust rod and a horizontal rod; the horizontal stabilizer rod with the function of a thrust rod is formed into a shape of rectangular C by fixedly connecting a section of horizontal rod and two sections of vertical boards, the middle horizontal rod is parallel to the axle, each of the two ends of the horizontal rod respectively passes through one end part of each vertical board and is fixedly connected with each vertical board, the inner sides of the two ends of the horizontal rod are respectively sleeved with round linings and are connected with the axle through connecting pieces; the other end of the vertical board is provided with a connecting hole in which a rubber lining is fixed, and the rubber lining is fixedly connected with the car frame bracket through the connecting pieces. The utility model has the advantages of simple and compact structure and low production cost, and can ensure the rotating character of the wheel.

Description

Novel double trailing arm type air suspension structure

(1) technical field

The utility model relates to a kind of air suspension of automobile structure.

(2) background technology

Existing double trailing arm type air suspension generally comprise the suspension guide mechanism that is connected between chassis side rail and the vehicle bridge, air bellow, bumper and with chassis side rail bonded assembly frame brackets, suspension guide mechanism generally is made up of lower thrust rod and Panhard rod, lower thrust rod and Panhard rod separate, non-integrative-structure.Because lower thrust rod and Panhard rod are two members separately, therefore must arrange parts such as suspension rod respectively, this structure has complex structure, compact, productive costs is high and mobility is not good shortcoming inadequately.

(3) utility model content

The purpose of this utility model provides a kind of novel double trailing arm type air suspension structure, and it is too complicated to solve existing air suspension of automobile structure, and is compact inadequately, the technical matters that productive costs height and mobility are not good.

For achieving the above object, the utility model adopts following technical scheme:

A kind of novel double trailing arm type air suspension structure, comprise the suspension guide mechanism that is connected between chassis side rail and the vehicle bridge, air bellow, bumper and with chassis side rail bonded assembly frame brackets, it is characterized in that: suspension guide mechanism is the Panhard rod of having held concurrently the propelling rod effect, upper thrust rod and lateral rod, held concurrently the Panhard rod of propelling rod effect by one section cross bar, two sections stringer boards are fixedly connected as the Contraband shape, middle cross bar is parallel with vehicle bridge, an end of two stringer boards is passed at the cross bar two ends respectively, and captive joint with stringer board, the inboard at cross bar two ends is with the cast lining respectively, and be connected with vehicle bridge by attaching parts, the other end of stringer board has connecting bore, connecting bore internal fixation rubber bush, rubber bush is captiveed joint with frame brackets through link.

Air bellow is positioned at the following or outside of chassis side rail.

Compared with prior art the utlity model has following characteristics and beneficial effect:

Suspension guide mechanism in the utility model is made up of Panhard rod, upper thrust rod and the lateral rod of the propelling rod effect of having held concurrently, adopted the Panhard rod of having held concurrently the propelling rod effect, traditional Panhard rod and lower thrust rod have been replaced, have simple and compact for structure, be convenient to the advantage that automotive suspension is arranged, productive costs is low, and can guarantee the motion characteristics of wheel, be applicable to the air suspension structure of self-propelled vehicle.

(4) description of drawings

The utility model is described in more detail below in conjunction with accompanying drawing.

Fig. 1 is a perspective view of the present utility model.

Fig. 2 is the structural representation of Panhard rod of having held concurrently the propelling rod effect.

Panhard rod, 1.1-cross bar, 1.2-stringer board, 1.3-rubber bush, 1.4-cast lining, 2-chassis side rail, 3-vehicle bridge, 4-bumper, 5-attaching parts, 6-air bellow, 7-frame brackets, 8-upper thrust rod, 9-lateral rod that Reference numeral: 1-has held concurrently the propelling rod effect.

(5) specific embodiment

Embodiment is referring to Fig. 1, shown in Figure 2, this novel double trailing arm type air suspension structure comprise the suspension guide mechanism that is connected between chassis side rail 2 and the vehicle bridge 3, air bellow 6, bumper 4 and with chassis side rail 2 bonded assembly frame brackets 7, air bellow 6 is positioned at the outside of chassis side rail 2, also can be positioned at chassis side rail 2 below.Its suspension guide mechanism is Panhard rod 1, upper thrust rod 8 and the lateral rod 9 of having held concurrently the propelling rod effect.The Panhard rod 1 of propelling rod effect of having held concurrently is fixedly connected as the Contraband shape by one section cross bar 1.1, two sections stringer boards 1.2, middle cross bar 1.1 is parallel with vehicle bridge 3, an end of two stringer boards 1.2 is passed at cross bar 1.1 two ends respectively, and captive joint with stringer board, the inboard at cross bar 1.1 two ends is with cast lining 1.4 respectively, and be connected with vehicle bridge 3 by attaching parts 5, the other end of stringer board 1.2 has connecting bore, connecting bore internal fixation rubber bush 1.3, rubber bush 1.3 is captiveed joint with frame brackets 7 through link.
