Title:
BUSH BEARING DEVICE, AND RACK AND PINION STEERING DEVICE FOR AUTOMOBILE, USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/080823
Kind Code:
A1
Abstract:
Provided are a bush bearing device and a rack and pinion steering device for an
automobile, using the bush bearing device. The bush bearing device can support
with a predetermined rigidity a rack shaft relative to the radial direction,
to the axial direction of a pinion. Further, the bearing device can support the
rack shaft so that the shaft can move in its axial direction with a low frictional
resistance. Also, in the bearing device, an influence of stress release caused
by creep deformation and heat history is reduced. The bush bearing (7) has a synthetic
resin bush (17) having a circumferential groove (16) in the outer peripheral
surface (15) thereof, an endless annular elastic member (18) fitted to the circumferential
groove (16) of the bush (17), a pair of inside inner peripheral surfaces (21, 22)
disposed on the bush (17) supported on the rack shaft (5) and symmetrical with
respect to the axis of the rack shaft, and a positioning means (19) for determining
the position of the bush (17) relative to the inner peripheral surface (12) of
a gear housing (6) in the direction(B).
