Lightweight front bracket of off-road military command vehicle

Abstract

The invention relates to a lightweight front bracket of an off-road military command vehicle. The front bracket comprises a front bracket main body, wherein the front bracket main body consists of a longitudinal beam connecting end, an upper control arm connecting end, an axle connecting end and a control arm connecting end which are sequentially distributed from top to bottom; three longitudinal beam mounting hole groups are formed in the longitudinal beam connecting end; a groove is also formed between the longitudinal beam mounting hole group A and the longitudinal beam mounting hole group B; reinforcing ribs are also mounted at the back of the longitudinal beam connecting end; upper control arm mounting holes are formed in the upper control arm connecting end; a round through hole is formed in the axle connecting end, and the thickness of the round through hole is the same as the wall thickness of the front bracket main body; axle connecting holes are formed in the periphery of the round through hole; the control arm connecting end adopts a tube structure, and the central through hole of the control arm connecting end is a control arm connecting hole. The lightweight front bracket disclosed by the invention has the advantages that the overall weight of the front bracket is changed from 56.95 into 34.8kg, and the weight reducing rate reaches 38.9%.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a lightweight front bracket of an off-road command military vehicle. Background technique [0002] As "energy saving and environmental protection" has become more and more a research topic of widespread concern, lightweight is also widely used in the field of ordinary vehicles, which can have excellent fuel-saving performance while improving handling. The fuel consumption of a car mainly depends on the displacement of the engine and the total mass of the car. On the premise of keeping the overall quality, performance and cost of the car unchanged or even optimized, reducing the weight of the car itself can increase output power, reduce noise, improve handling, and reliability. Performance, increase vehicle speed, reduce fuel consumption, reduce exhaust emissions, and improve safety. Research figures show that if the weight of the vehicle is reduced by 10%, the fuel ef...

Problems solved by technology

[0003] For the front bracket used to connect the axle, longitudinal beam, upper control arm and control arm in the off-road command military vehicle, since there are many holes for connecting parts, reinforcing ribs will be set accordingly to ensure its structural strength, while When the traditional reinforcement is installed, the reinforcement itself will be as thick as the diameter of the hole, and the weight of the front bracket will be increased accordingly; in addition, for the installation hole used to install the longitudinal beam, the wall thickness will be thicker than that of the front bracket at the corresponding position. The thickness of the bracket itself is thicker, which increases the weight of the front bracket accordingly; in addition, there is a circular through hole at the axle connection part, and the circular through hole will also be made smaller than the front bracket itself at the corresponding position during production. The wall thickness of the wall should be thicker, and finally the weight of the front bracket reaches 56.95kg
