A Wheel axle suspension for attaching a wheel axle to a vehicle chassis, comprises a trailing arm extending crosswise to the axle body and an axle pad which is arranged between the axle body and the trailing arm.

The wind-wheel axle (15) is supported by a bearing (6).

The rotation center (C1) of the main guided wheel (31) is eccentric with respect to the axle center (C2) of the wheel axle (4).

The lower end of the wind-wheel axle (15) is withdrawn in the head housing (4) and connected with the drilling needle (3).

A powered wind-wheel (7) and a wind-wheel axle (15) driving the drilling needle (3) to rotate are mounted in the space which the head housing (4) and a head cap (8) enclose.

The washer (18) includes a tab (24) received in a slot (26) of a wheel spindle (28) to permit the washer to move axially and prevent the washer from rotating.

In the preferred embodiment, the leverage arms (30, 40) and shock-absorbing component (50) pivotally connect a vehicle chassis to a vehicle wheel spindle (26).

The closed outer end of the brake drum includes a centrally located wheel spindle opening (24) formed therein, and a plurality of lug bolt mounting holes (26) spaced circumferentially around the wheel spindle opening.

The rotor frame includes a stub axle that engages with the bearing element and features to provide torsional or rotational compliance between the rotor magnets and the fan.

A sealing member is carried by the flange for forming an airtight seal with the axle spindle.

The segments move radially outwardly upon the locking assembly being moved along the inclined arbor portion and engage the axle spindle, securing the plug assembly within the spindle.

A fastening member threadably engages the arbor for urging the locking assembly along the inclined arbor portion to effect securement of the plug assembly within the axle spindle.
