Abstract

Abstract A vehicle steering column is divided into an upper and a lower column section connected through a bevel gear unit. The two sections are off-set and may be adjusted to different angular positions. An impact axial force of a predetermined magnitude on any of the column sections will release the connection between the column sections in order to prevent that excessive impact forces are transmitted to the driver.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 246 words
A steering gear for wheel-driven vehicles, especially for automobiles, comprising a steering column divided into two sections, namely at least one lower steering column section connected to wheel steering means such as a steering worm, and at least one upper steering column section, to which the steering wheel of the vehicle is attached, the two steering column sections being interconnected by means of a torque transmitting system of gears which permit mutual axial relative movement of the sections, characterized in that the two steering column sections are off-set in relation to each other and, have their ends journalled in a housing and support therein each a column bevel gear wheel, said two gear wheels being drivingly interconnected by an intermediate member provided with a bevel gear wheel at both endS in engagement with said column bevel gear wheels on said sections and rotatably mounted in bearings in said housing, said housing being partitioned at its middle into two halves which are rotatably adjustable relative one another to different positions to enable the column sections to form different angles with each other, and said housing being adjustably positioned along a circular arc guide having its centre at the lower end portion of said lower steering column section, means being provided for locking said housing and said halves of the housing in the desired position along said path and relative one another respectively, to obtain the desired position of said upper and lower column sections relative one another.
Claim 2
Dependent Claim 246 words
A steering gear for wheel-driven vehicles, especially for automobiles, comprising a steering column divided into two sections, namely at least one lower steering column section connected to wheel steering means such as a steering worm, and at least one upper steering column section, to which the steering wheel of the vehicle is attached, the two steering column sections being interconnected by means of a torque transmitting system of gears which permit mutual axial relative movement of the sections, characterized in that the two steering column sections are off-set in relation to each other and, have their ends journalled in a housing and support therein each a column bevel gear wheel, said two gear wheels being drivingly interconnected by an intermediate member provided with a bevel gear wheel at both endS in engagement with said column bevel gear wheels on said sections and rotatably mounted in bearings in said housing, said housing being partitioned at its middle into two halves which are rotatably adjustable relative one another to different positions to enable the column sections to form different angles with each other, and said housing being adjustably positioned along a circular arc guide having its centre at the lower end portion of said lower steering column section, means being provided for locking said housing and said halves of the housing in the desired position along said path and relative one another respectively, to obtain the desired position of said upper and lower column sections relative one another.
Claim 3
Dependent Claim 116 words
A steering gear according to claim 1, characterized in that each column passes through a bearing in the wall of the respective half of the housing and has its end journalled in a bearing provided in a lid or cover detachably mounted in an opening in the wall of the housing so that when the respective column section presses on the lid or cover with a predetermined axial force, the cover will leave its seat and permit axial displacement of the column section relative to the housing, said opening having a greater diameter than the diameter of the bevel gear on the column section to permit the bevel gear wheel to pass out through said opening.
Claim 4
Dependent Claim 61 words
A steering gear according to claim 2, characterized in that the two housing halves are provided each with a circular flange at the inner end of the respective half of the housing, said flanges being in contact with each other and having axial bores for receiving a locking pin to lock the halves in the desired angular position relative one another.
Claim 5
Dependent Claim 53 words
A steering gear according to claim 3, characterized in that the two circular flanges of the housing are guided in an upper and a lower rail with U-section and forming a circular arc path guide for the housing, and that means are provided for locking the housing in different positions along said path.
