Talk about car chassis design concept Chassis design and development The key lies in the chassis design considering to meet the targets of vehicle performance, the basic performance of the car should have can be summarized as the power and economy performance, stability, braking performance, comfort, safety and durability. configurantion design of chassis engineering general said, including front and rear suspension, steering system, braking system and wheel. Vehicle performance is directly related to the system of braking performance, operation stability and smoothness. Chassis suspension parts itself should be strong enough, and its design is directly impact force size frame body, and the chassis design and durability of. For example, the chassis design projects and other design projects closely combined, on both sides of the front longitudinal beam position, vehicle length width has certain requirements. The configuration and function of chassis components Composed of automobile chassis consists of four parts, namely, powertrains, braking system, steering system and suspension system. From vehicle dynamics point of view, the car straight driving and braking belongs to car in longitudinal motion, riding comfort is mainly in the vertical and pitching direction control, and to involve car lateral, yawing and roll movement. Generally, is ideal for evaluation of a model, the main evaluation index including good power performance, low fuel consumption, low emissions, good braking performance, comfort, no vibration noise interference, steering and lane changing smoothly. Dynamic assembly and brake system Related parts have a powertrains engine, exhaust system, gearbox, drive shaft, differential, axle, wheel and brake assembly. 4 x4 and differential device, heavy trucks and military vehicles and six drive, to increase the driving force, many differential will differential lock, it is used to prevent the wheels because of the different friction between the left and
