Description

Light frame assembly for short-wheelbase mixer truck

Technical Field

The utility model belongs to the technical field of vehicle accessories, and particularly relates to a lightweight frame assembly for a short-wheelbase mixer truck.

Background

The frame is a frame structure which is bridged on the front axle and the rear axle of the automobile, commonly called a girder, and is a matrix of the automobile. The vehicle is generally composed of two longitudinal beams and a plurality of transverse beams, and is supported on wheels through a suspension device, a front axle and a rear axle. The frame must have sufficient strength and rigidity to withstand the load of the vehicle and the impact transmitted from the wheels. The frame is used for supporting and connecting the assemblies of the automobile, so that the assemblies maintain relatively correct positions and bear various loads inside and outside the automobile.

Most modern automobiles have a frame as the skeleton of the entire automobile. Most parts and assemblies of automobiles are secured by frames such as engines, drivetrains, suspensions, steering systems, cabs, cargo containers and related operating mechanisms. The frame plays a role in supporting and connecting various parts of the automobile and bears various loads from the inside and the outside of the automobile.

The structural form of the frame should firstly meet the requirements of the overall arrangement of the automobile. During complex driving of the vehicle, no interference should occur between the assemblies and components fixed to the frame. When the automobile runs on a rugged road, the frame can generate torsion deformation and bending deformation in a longitudinal plane under the action of load; when one side of the wheel encounters an obstacle, the whole frame may also be distorted into a diamond shape. These deformations will change the relative position between the components mounted on the frame and thus affect its proper functioning. Therefore, the frame should also have sufficient strength and appropriate rigidity. In order to improve the light weight level of the whole automobile, the frame quality is required to be as small as possible. In addition, the frame should be arranged closer to the ground so that the center of gravity of the automobile is lowered, thereby facilitating the improvement of the running stability of the automobile. This is particularly important for passenger cars and cars.

At present, the weight of a heavy-duty car frame accounts for about 10% of the whole car preparation quality, the weight of the frame means the strength assurance of a supporting structure, and the direct weight reduction of the frame in the prior art can reduce the structural supporting strength. Therefore, the development of a lightweight frame is a key for reducing the quality of whole vehicle preparation.
