products are now selling more expensive, but there are only getting cheaper car trend, manufacturers really stupid it? Whether human or material costs and processing costs are increasing now, and why cars can sell it cheaper, it just because mass production to reduce costs brought about by it? but starting from the Ford assembly line production to reduce costs now standardized production brought about by the increasingly obvious in today’s car market so the major manufacturers need to use a variety of concepts to drive sales, while reducing some configuration between the consumer inadvertently, these configurations are often overlooked but very practical consumers, although individual configuration cost is not high, but always out of sheep wool, car selling cheaper, exactly what configuration it with a minus.
chassis armor coating
Now many vehicle even suv vehicle for spraying chassis armor have been reduced with the chassis armor is a special coating, having high strength and high tack can be protected by a cover, generally used for preventing corrosion of rust chassis, fuel tanks and other protective surface coating. Chassis armor material cost of the vehicle body other than itself to cost of paint, and requires a special device for spraying a robot to be able to hit the cover of a uniform design requirements. Some low-end model sites armor employed in order to save cost, spraying is not uniform, and the thickness is thin, is not able to play a very good protection of the chassis occurs when scratched. And in the end some models, because the chassis of the materials is better than low-end models, so the manufacturer is simplified with the chassis armor, and that better use of materials may also play a role in anti-rust but the fact is far from satisfactory.
Thickness
chassis armor usually about three to four millimeters, too thick, too thin, easily peeled off not achieve very good protective effect may also effect chassis armor heat isolation functions chassis parts, in particular the heat generated by the exhaust pipe, can ensure a constant temperature occupant leg optimize ride experience occupant. Post-consumer modified chassis armor, because most artificial spray, spray evenly quality not as good as the original robot, so choose the best choice car chassis of the original painting.
engine guard
Now Speaking engine guardMany old driver board will say, bad road conditions now are no longer needed engine guard, and will increase its own weight, causing eddy current chassis parts increase air resistance, of course, there is some truth to urban users, but for most of suv ground clearance vehicles and small cars, still need the engine guard. Now engine guard plate material, there are mostly plastic and metal, the metal shield is welded to the engine on the frame, while the plastic material is fitted in the positioning groove by a snap or a screw. Many manufacturers in the fate of the chassis parts are engine guard slot, but it is not equipped with engine guard, engine guard to know that the standard configuration, but around 2000. Tiles
of the exhaust pipe
of the exhaust pipe at the same tiles that many consumers will be ignored, even Some professional maintenance master also tend to ignore this configuration. An exhaust pipe arranged in the lower chassis, usually isolated tiles temperature, in particular the temperature of the three-way catalyst section, transmitted to the cockpit by a chassis, dramatic temperature changes affect the legs of the occupant rides, and even reduce the chassis rubber member of life, so the tiles is very important, but because the tiles are not easily seen by consumers, so manufacturers often simple with this configuration.
In fact, in parts of the chassis tiles post-conversion costs are not high, but add up to the cost of weakening the rider’s riding experience.
Chassis noise
of the noise on the vehicle is well known that many consumers must cotton insulation of the engine compartment and the cabin, but in fact the sound also important parts of the chassis, parts of the chassis and noise compared to other parts of the sound, more costly, and designed to maintain its durability. Typically chassis parts using the sealing barrier pass noise insulation plastic, rubber or a more advanced device, the rigid member to cushion the impact of noise, most manufacturers now are omitted glue sealing and damping chassis is selected in a thicker carpet laying vehicle to noise, but these carpet manufacturers will use a lot of black heart black heart cotton, will endanger the health of passengers.
Chassis connecting rod and the fixed rod
parts of the chassis and the connecting rod is fixed rod portion of the chassis reinforcing member significant height, although greatly improved the quality of steel and high-strength steels have been widely used, but the rigidity of the chassis portion itself is also related to the high speed of the vehicle traveling performance and ultimate control experience, the vehicle chassis and the connecting rod is secured to enhance a sense of lateral and transverse stiffness of the chassis, many manufacturers now because of cost control, the accuracy of these problems will be difficult to install additional chassis member is omitted, with respect to the chassis stiffness indeed worrying.
Materials swing arm (simply dubbed stamping forging material)
Since the off axis of the door occurs after the traverse chassis and suspension Object stampings became everyone’s concern, I do not know wishbone suspension from many manufacturers since when have become stampings, stamping parts really cost the equivalent of forging material change from the original one-third of the cost of forged parts and the way in this plant is only enough level, unable to meet consumer demand for higher power conversion, especially so if your car uses a mid-size car stamping parts manufacturers so really not enough good faith. Forging the weight of the stamping almost the same, and the name does not reduce the unsprung mass to less with the cover.
As a vehicle chassis with texture actuating member important, if your car manufacturers of these parts were arranged chassis reduction with, consumers can choose own late conversion to achieve the perfect chassis driving function.
