A Guide Arm Bracket Structure for Air Suspension

Technical Field

The utility model relates to the technical field of brackets, in particular to a guide arm bracket structure for an air suspension.

Background Art

A high-quality SUV needs to provide both the comfort of a passenger car and the passing performance of an off-road vehicle. An air suspension system is an optimal choice for achieving this goal. An air suspension mainly consists of a control computer, air inlet, air outlet, pneumatic front and rear shock absorbers, and an air distributor. It controls the horizontal posture of the vehicle body and adjusts the vehicle body stability system.

Since its emergence in the mid-19th century, air suspension has undergone more than a century of development, including various forms such as pneumatic spring airbag composite suspension, semi-active air suspension, and central inflation and deflation suspension. It was not until the 1950s that air suspension began to be applied to heavy-duty trucks, buses, passenger cars, and railway vehicles.

At present, almost all high-end buses abroad use air suspension, and the proportion of heavy-duty trucks using air suspension has reached more than 80%. The application of air suspension in light vehicles is also increasing rapidly. Some passenger cars have also gradually begun to use air suspension. In certain special vehicles, such as instrument vehicles with high vibration resistance requirements, ambulances, special military vehicles, and container transport vehicles with specific requirements, air suspension is almost the only option.

An air suspension needs to be installed by relying on a guide arm. However, the existing bracket structures are inconvenient for telescopic adjustment when installing the guide arm, have poor applicability, and are not convenient for assisting the use of the guide arm. Therefore, a guide arm bracket structure for an air suspension is proposed to solve the above problems.

The two first brackets are vertically arranged, and the upper and lower ends of the two first brackets are connected by horizontally arranged second brackets. Each of the two first brackets comprises a vertically arranged first support plate. The two first support plates are hollow structures, and a vertically arranged second support plate is arranged between the two first support plates. Both ends of the second support plate are connected to the bottom wall of the first support plate through first connecting mechanisms. Guide arm auxiliary fixing mechanisms are fixedly connected to the side walls of the two second support plates facing each other.

Preferably, the second bracket comprises a horizontally arranged third support plate. The third support plate is a hollow structure, and two symmetrically arranged fourth support plates are arranged inside the third support plate.

A first opening matched with the first sliding plate is arranged on the side wall of the first support plate, and the first sliding plate passes through the first opening. A sliding locking block matched with the first sliding plate is arranged on the side wall of the first support plate.

Preferably, the guide arm auxiliary fixing mechanism comprises a clamping block. The clamping block is provided with a clamping groove whose opening faces away from the second support plate. Two symmetrically arranged clamping plates are arranged inside the clamping groove, and the two clamping plates are connected to the inner wall of the clamping groove through a plurality of second springs. Pull rods are fixedly connected to the side walls of the two clamping plates facing away from each other, and the pull rods pass through the side wall of the clamping block.

Preferably, the second connecting mechanism comprises two symmetrically arranged second sliding plates. The two second sliding plates are connected by a plurality of third springs. A second opening matched with the two second sliding plates is arranged on the side wall of the third support plate.

Preferably, mounting blocks are fixedly connected to the opposite ends of the two first support plates, and mounting screws are arranged on the two mounting blocks.

The utility model has the following beneficial effects:

The two second sliding plates can slide inside the third support plate, thereby adjusting the working distance between the two fourth support plates and the working distance between the two second support plates. The clamping plate can lock the two second sliding plates, ensuring the stability of the working state of the two fourth support plates.

The first sliding plate can slide on the first support plate, thereby adjusting the working distance between the two first support plates. The sliding locking block can lock the first sliding plate, ensuring the stability of the working distance between the two first support plates. The two clamping plates, in cooperation with a plurality of second springs, assist in fixing the guide arm. The mounting blocks cooperate with the mounting screws to facilitate auxiliary installation of the guide arm.
