Abstract:
[PROBLEMS] A support structure for a suspension device, increased in rigidity
and reduced in weight and cost. [MEANS FOR SOLVING PROBLEMS] The support structure
is constructed from a double-axle suspension. An upper rotation mechanism
(4) of the support structure has an upper pivot shaft (29) detachably joined to
a vehicle body-side knuckle (2) by a fixation bolt (28) and also has an upper support
bearing (30) installed between the upper pivot shaft (29) and a wheel-side knuckle
(1). The upper support bearing (30) is a back-to-back mounted full complement
roller-type double-row tapered roller bearing having an outer ring (31) fitted
in a hollow cylindrical section (1a) of the wheel-side knuckle (1) and having,
formed on its inner periphery, tapered double-row outer rolling surfaces (31a),
a pair of inner rings (33) having, formed on its outer periphery, double-row tapered
inner rolling surfaces (33a) facing the double-row outer rolling surfaces (31a),
and double-row tapered rollers (32) rollably received between the rolling surfaces.
The upper support bearing (30) is filled with a solid lubricating agent (37).
