Description
Technical Field
The utility model relates to a preceding sub vehicle frame especially relates to a preceding sub vehicle frame that electric motor car "worker" style of calligraphy simple structure is firm.
Background
With the requirements of national policy propulsion and environmental protection, the electric automobile is developed more and more rapidly, parts of the electric automobile are also continuously developed, and the front auxiliary frame is also widely adopted in the electric automobile. The front auxiliary frame provides mounting points for a stabilizer bar system, a steering system, a suspension system, a driving system and the like, and is an important safety and bearing part. It supports all sprung masses and simultaneously withstands and transmits the various forces and moments which occur during the driving of the vehicle. Therefore, the rigidity, strength, mode shape, fatigue life, and the like of the subframe play an important role in the safety reliability, the operational stability, and the riding comfort of the entire vehicle.
The auxiliary frame is mainly formed by main body frame and the combination of each type of support of connecting in main body frame, and the technology is mostly the tailor-welded combination of punching press sheet metal component, or the tailor-welded combination of tubular beam structure and panel beating, or aluminum alloy casting etc.. The general classification is as follows: the structure can be divided into a frame type auxiliary frame, a butterfly type auxiliary frame, a Pi-shaped auxiliary frame and the like; the driving form of the whole vehicle can be divided into a front driving type front auxiliary frame, a rear driving type front auxiliary frame and the like; the material can be divided into a steel part front auxiliary frame, an aluminum alloy front auxiliary frame and the like; the process can be divided into a welding type front sub-frame, a casting type front sub-frame, and the like.
The front auxiliary frame is limited by multiple hard points and installation space, and in order to meet the requirements on rigidity, strength, mode and fatigue life, the design structure of the front auxiliary frame is complex, and more welding procedures are needed to meet the design requirements in the process. The existing steel part front auxiliary frame has larger weight, does not achieve the purpose of light weight, and simultaneously has not ideal part precision and production cost. The traditional fuel oil automobile can accept a front auxiliary frame with heavier weight and higher cost, but for the electric automobile, higher requirements are put forward on the front auxiliary frame, the whole weight is smaller, the rigidity is good, the reliability is better, the whole automobile weight of the electric automobile is favorably lightened, and the endurance mileage of the electric automobile is effectively prolonged.
However, the front subframe of the electric vehicle not only meets the installation requirements of the traditional stabilizer bar system, the traditional steering system and the traditional suspension system, but also needs to provide installation points and installation space for the electric system, so that the battery is protected, the functional requirements are more, the structure is more complex, the weight is larger, and the assembly process is more. Casting aluminum alloy auxiliary vehicle or aluminium alloy welding sub vehicle frame possess certain lightweight advantage, but its cost will be than steel part sub vehicle frame and exceed 2 to 4 times, and its is costly unable to accept of many car enterprises, and domestic enterprise is all less to aluminium part sub vehicle frame design and production experience, and market verification is also not abundant yet, and aluminium part sub vehicle frame's popularization still needs longer time. Therefore, the design of the front auxiliary frame of the existing steel part meets the requirements of strength, rigidity, mode, fatigue life, arrangement space and the like, and the lightweight design and cost control are more urgent, so that the design becomes an important assessment factor of the front auxiliary frame.
Therefore, how to provide a front subframe with simple structure, stability and low cost is an urgent technical problem to be solved by those skilled in the art.
