Abstract
Abstract In a vehicle the steering system includes a steering gear housing transversely mounted relative to the vehicle body by means of a plurality of gear housing mount insulators. Each of the gear housing mount insulators elastically supports the gear housing in such a manner as to allow transverse displacement of the gear housing with respect to the vehicle body. A damper is provided to restrain the transverse displacement allowed by the gear housing mount insulators.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
92 words
In a vehicle having a vehicle body and a change-direction road wheel, a steering system including: a steering gear and a gear housing having received therein said steering gear; gear housing mount insulator means for elastically supporting said gear housing on the vehicle body in such a manner as to allow transverse displacement of said gear housing; and restraining means independent of the support of said gear housing by said gear housing mount insulator means for restraining said tranverse displacement of said gear housing allowed by said gear housing mount insulator means.
Claim 2
Dependent Claim
92 words
In a vehicle having a vehicle body and a change-direction road wheel, a steering system including: a steering gear and a gear housing having received therein said steering gear; gear housing mount insulator means for elastically supporting said gear housing on the vehicle body in such a manner as to allow transverse displacement of said gear housing; and restraining means independent of the support of said gear housing by said gear housing mount insulator means for restraining said tranverse displacement of said gear housing allowed by said gear housing mount insulator means.
Claim 3
Dependent Claim
38 words
In a vehicle as claimed in claim 1, wherein said restraining means comprises a damper which is operatively connected to the vehicle body and said gear housing so as to control said transverse displacement of said gear housing.
Claim 4
Dependent Claim
58 words
In a vehicle as claimed in claim 2, wherein said damper has a cylinder body, fixedly connected to the vehicle body, a piston fixedly connected to said gear housing and slidably disposed in said cylinder body to define two fluid-filled chambers communicating with each other via a fluid passage and means for restricting fluid flow through said passage.
Claim 5
Dependent Claim
48 words
In a vehicle as claimed in claim 1, wherein said restraining means includes a vehicle speed sensor sensing a vehicle speed of the vehicle and generating a sensor output signal, a damper, and means for controlling the characteristic of said damper in response to said sensor output signal.
Claim 6
Dependent Claim
46 words
In a vehicle as claimed in claim 4, wherein a force produced by said damper for restraining said transverse displacement of said gear housing is large when the vehicle runs at low vehicle speeds as compared to that when the vehicle runs at high vehicle speeds.
Claim 7
Dependent Claim
29 words
In a vehicle as claimed in claim 4, wherein said restraining means completely hampers said transverse displacement of said gear housing when the vehicle runs at low vehicle speeds.
