Problems solved by technology

Especially on the air suspension, the connection with the axle 2 of the semi-trailer is basically installed on the suspension assembly 1 by welding. Some manufacturers add U-shaped bolts 4 on the basis of welding to connect the two. The disadvantage of this method is that the shaft body is prone to cracking or even failure near the welding position; the bolts are prone to loosening after a long period of transportation of the car, which makes the ratio of traffic accidents where the shaft and the frame are separated is very high. This double combination method increases the processing steps and complexity, and the economic benefit is low

Embodiment Construction

[0021] like Figures 2 to 5 As shown, the fully welded air suspension coupling structure of the present invention includes a suspension assembly 1 and an axle 2. The suspension assembly 1 includes a main beam 11, an air spring 12, a shock absorber 13 and a front bracket 14. The specific structure as follows:

[0022] The main beam 11 is inwardly recessed to form an open arched axle seat 15 for installing the axle, and the outline of the installation part of the open arched axle seat 15 is in the shape of a inferior arc. Further, the open arched axle The contour of the installation part of the seat 15 is a minor arc shape greater than 120° and less than 180°, wherein, as a preferred embodiment, the contour of the installation part of the open arched shaft seat 15 is a minor arc shape of 170°, due to the open The profile of the installation part of the arched axle seat 15 is less than 180° semicircle. On the one hand, it reduces the material used for the main beam 11. On the ot...

Abstract

The invention discloses an all-welded air suspension coupling structure. It includes a suspension assembly and an axle, the suspension assembly includes a main beam, and an open arched axle seat for installing the axle is arranged on the main beam. ; The open arched axle seat is half-encircled and welded to fix the axle. An axle sleeve is arranged between the axle and the open arched axle seat, and the outside of the axle sleeve is welded and fixed with the open arched axle seat, and the inside of the axle sleeve is welded and fixed with the axle. The present invention welds and fixes the axle by setting an open arched axle seat on the suspended main beam, which has a simple structure, firm and reliable connection, can reduce the manufacturing materials and the complexity of the processing technology, and eliminate the potential safety hazard caused by the semi-welded connection of the bolts .

Description

technical field [0001] The invention relates to a suspension coupling structure, in particular to a fully welded air suspension coupling structure applied to a trailer. Background technique [0002] Today's cars are equipped with suspension structures. Suspension is a general term for all force-transmitting connection devices between the car's frame and axles, axles or wheels. The main function of the suspension is to transmit all forces and forces between the wheels and the body Moment, such as supporting force, braking force and driving force, etc., and ease the impact load transmitted to the body from the uneven road surface, attenuate the vibration caused by it, ensure the comfort of the occupants, and reduce the dynamic load of the cargo and the vehicle itself. The existing automobile axle and frame are firmly connected by suspension. At present, leaf spring suspension and air suspension are commonly used, and air suspension can improve the ride comfort and comfort of t...
