REAR AXLES DO DIFFER

Though Mgs hmk The Same To Th§ Unimtiatgci

To the eye of ti^et uninitiated every rear axle assembly is constructed <$pn£ f|if tti&ft fees, but \yfnle substantially \f^s is. the case, axl§^ ape diy||e^ initp thrpe ijiipprtant cat|gprie^^ Jcjpwn as the semi-^Patiin^,^^ ftgatin^, "anij fuli-ffo^ui^ fyyes.

IN the first variety the axle shafts carry the whole weight of the car. The wliee? is 'mounted directly on the tapered extremity ''of- t]ie axle, and is supported by no other p'irt. : '= " 1 The bearing m yvhjch th? gx|e revolves Is contained ; vylthin : tHe axle Hpusinq. This constpuptjpn, it wrilj be '■. f'een,"' exerts a certain amount of leyerage oh ihjs bearing. . The .three-quarter floating a^le is substantially the srtmej ; but "the position of tKe'bean^g' is located 'right inside t|ie''-v^h ; eei, :: and although the : axle still takes all tlie" weight it is exerted vertically ' ort ' this bearing.: ■ ' '

In the full-flo^tingr axle, thp -vyheel is mpuntecl f dn thp axl^ hpiasing, an ' antifricß'on bearingr being- iriteppos'ed between.the two'Tparts, arid th*e drive is transmitted to the wheel by- tlie hub, which }s first bpltpd to the end' of' the axlb stiq.fi and th4n >to the wheel. In this construction the axjg is not called upon tp'.stapd'ahy ".of the vy^jgjit,' but pnjy to transmit tpe driyfe.' ; ' ■'■' : ':' ; -- ■ ■ ■ '"' ; -For the rest, the construction of the average axle is niade pifiip by the : diagram,'; and tlie posltipri and • types of most of the ahti-friction bearing^ iised extensively wiirbehpted. • '
