De Dion axle

De Dion axle is now rarely used type of construction of the rear drive axle. This design combines the advantages of independent suspension and solid axle. Unlike the angular wheel axles are connected De Dion axle rigid beam, which is fixed to their relative position (similar to a solid axle). But unlike the solid rear axle is driven De Dion axle with axle connected to the frame or bodywork is a part of suspended materials.

Driven solid axles have a large part of the unsprung mass (ie, worsening driving performance when crossing uneven). This weight can be reduced by separating final drive axle from the bridge, just as is the case with De Dion axle. De Dion axle its design combines the advantages of independent suspension (lower unsprung mass) and rigid axle (non-variable position due to road bikes and each other). This axle was coined by Count De Dion in 1896.

De Dion axle wheels are connected to a rigid beam, which guarantees their status. The rigid beam is established transversely in the frame or body using Panhardské bars or přímovodem watt , which are recorded lateral forces. axle is positioned on a rigid axle, but it is firmly connected to the frame or body and is therefore part of the sprung mass. The transmission of the torque transmission shafts care whose weight is partially attributed to neodpruženým hmotám. Compared to the solid axle De Dion axle lower unsprung mass, because it uses (used) a number of sports cars.

Alfa 75 - De Dion axle

The picture shows the axle De Dion car Alfa Romeo 75th The wheels are connected to a rigid cross beam guided under the axle and two sloping shoulders. Sloping shoulders are fixed on the body (or subframe) and ensure the establishment of longitudinal axle. Cross axle establishment is realized přímovodem watt . Disc brakes are located directly at the axle, causing a further reduction in unsprung weight.
