is a monocoque vehicle chassis structure, the vehicle body load to the wheels by the suspension means. Monocoque has a small mass, low height, easy to assemble, good high speed stability and the like, present most cars using this body structure.
1. Monocoque the noun
is a monocoque chassis construction of a vehicle, which load the body to the wheels by the suspension means. Monocoque has a small mass, low height, easy to assemble, good high speed stability and the like, present most cars using this body structure.
monocoque vehicle chassis is not rigid, but the strengthened front, side panels, the rear portion of the bottom plate and the like, the engine, front and rear suspension, a portion of a drive train assembly, and other member fitted in the desired position on the vehicle body design, load of the vehicle body to the wheels by the suspension means. This unibody addition to its inherent function of the ride, but also directly receives the force of the various loads. After decades of development and improvement, Unibody, whether in security or in terms of stability has greatly improved, with a low mass, high and low, no hangingCounter means, easy assembly, etc., so that most of the car body structure adopted.
2. Monocoque features
no monocoque frame, the frame body of the vehicle and play the role of all the components fixed car body, all forces have come to bear by the body. Thus unibody and uses a completely different non-bearing
The monocoque body portion (side panels, pillars, roof, etc.) are under the ground, the suspension pass over the vibration, pressure, rather than carrying the formula only the chassis to withstand these.
advantages:
● frameless, reduce vehicle mass;
● Cabin structure does not affect the space, to reduce the body height, on and off convenient;
● suitable for cars, car, and this urban SUV hybrid species vehicles, lighter, fuel-efficient.
● low center of gravity, smooth highway driving, unibody safer.
disadvantages:
● drivetrain and suspension vibration and noise will be passed directly to the car, shockproof and sound insulation measures need to be taken;
[123 ] ● chassis beam intensity is far better than the structure of the vehicle body, when the discontinuity four wheels, the vehicle body will be deformed;
● high manufacturing cost.
● only suitable for driving on good roads, bad roads through sexual difference, uneven road surface may cause drag the bottom
