Abstract
Abstract A variable length tie rod assembly includes a tie rod and a ball and socket assembly. The ball and socket assembly has a socket housing with a ball stud disposed in the socket housing. A tie rod extends into the socket housing. The variable length tie rod assembly includes adjustment means for effecting relative movement between the ball and socket assembly and the tie rod. The adjustment means includes a pinion rotatably mounted in the socket housing. The pinion has teeth disposed in meshing engagement with teeth formed in one end portion of the tie rod. The pinion is rotatable relative to the socket housing to effect axial movement of the tie rod relative to the socket housing.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
214 words
An assembly comprising: a tie rod having an end portion with teeth formed thereon; a ball and socket assembly comprising a ball stud and a socket housing, said socket housing having a first housing portion for receiving said ball stud and a second housing portion for receiving said end portion of said tie rod; a pinion having a plurality of teeth for engaging said teeth formed on said end portion of said tie rod and rotatable to effect relative axial movement between said socket housing and said tie rod; said second housing portion having means for supporting said pinion for rotation relative thereto to effect said relative axial movement between said socket housing and said tie rod; and means disposed adjacent opposite axial ends of said pinion for applying force against opposite portions of said second housing portion to press said opposite portions of said second housing portion against said tie rod to hold said tie rod against axial movement relative to said socket housing and to simultaneously lock said pinion against rotation, said force applying means being releasable to relieve said opposite portions of said second housing portion from pressing on said tie rod and to enable rotation of said pinion to effect axial adjustment between said tie rod and said socket housing.
Claim 2
Dependent Claim
214 words
An assembly comprising: a tie rod having an end portion with teeth formed thereon; a ball and socket assembly comprising a ball stud and a socket housing, said socket housing having a first housing portion for receiving said ball stud and a second housing portion for receiving said end portion of said tie rod; a pinion having a plurality of teeth for engaging said teeth formed on said end portion of said tie rod and rotatable to effect relative axial movement between said socket housing and said tie rod; said second housing portion having means for supporting said pinion for rotation relative thereto to effect said relative axial movement between said socket housing and said tie rod; and means disposed adjacent opposite axial ends of said pinion for applying force against opposite portions of said second housing portion to press said opposite portions of said second housing portion against said tie rod to hold said tie rod against axial movement relative to said socket housing and to simultaneously lock said pinion against rotation, said force applying means being releasable to relieve said opposite portions of said second housing portion from pressing on said tie rod and to enable rotation of said pinion to effect axial adjustment between said tie rod and said socket housing.
Claim 3
Dependent Claim
43 words
An assembly as set forth in claim 1 wherein said pinion has teeth projecting from a body and said tie rod includes a surface for engaging said body of said pinion to block axial movement of said tie rod from said socket housing.
Claim 4
Dependent Claim
110 words
An assembly as set forth in claim 1 wherein said socket housing comprises base and cover sections defining said opposite sides, said cover section including a lip received in a portion of said base section to interconnect said base and cover sections, and said force applying means comprises a head end portion of said pinion engageable with an outer surface of one of said base and cover sections, a threaded end portion projecting beyond the other of said base and cover sections and a nut for threadingly engaging said threaded end portion of said pinion and engageable with an outer surface of the other of said base and cover sections.
