A telescopic shaft comprises an inner shaft, an outer shaft, which defines a tube and surrounds a part of the inner shaft and which is movable in the axial direction in relation to the inner shaft, two ball tracks arranged in the inner shaft, and balls arranged in the ball tracks. Each one of the ball tracks comprises an outer ball track portion, which is partially open so that the balls are arranged to roll between the outer ball track portion and the inside of the outer shaft. The telescopic shaft comprises at least one movable ball track member and a spring member which is arranged to press the movable ball track member and the balls arranged in the ball track member against the inside of the outer shaft in order to pretension the telescopic shaft.
A telescopic shaft (2) for motor vehicles (1) is described. The telescopic shaft (2) comprises an inner shaft (3), an outer shaft (5), which defines a tube and surrounds a part of the inner shaft (3) and which is movable in the axial direction in relation to the inner shaft (3), two ball tracks (8, 9) arranged in the inner shaft (3), and balls (10) arranged in the ball tracks (8, 9). Each one of the ball tracks (8, 9) comprises an outer ball track portion (11), which is partially open so that the balls (10) which are arranged in the outer ball track portion (11) are arranged to roll between the outer ball track portion (11) and the inside of the outer shaft (5). The telescopic shaft (2) comprises at least one movable ball track member (12) which constitutes at least part of the outer ball track portion (11) and a spring member (13) which is arranged between the inner shaft (3) and the movable ball track member (12), which spring member (13) is arranged to press the movable ball track member (12) and the balls (10) arranged in the ball track member against the inside of the outer shaft (5) in order to pretension the telescopic shaft (2).

F16C 3/035 - ShaftsAxles telescopic with built-in bearings
F16C 29/06 - Ball or roller bearings in which the rolling bodies circulate partly without carrying load
F16D 3/06 - Yielding couplings, i.e. with means permitting movement between the connected parts during the drive adapted to specific functions specially adapted to allow axial displacement
A telescopic shaft for vehicles comprising an inner shaft axially movable in an outer shaft. The telescopic shaft comprises at least two rows of balls with at least one ball per row between the inner shaft and the outer shaft. A row of balls is arranged on at least one ball race arranged against the inner shaft. The ball race is wedge shaped on its against the inner shaft facing surface. The telescopic shaft comprises a prestress mechanism which pushes the ball race along a wedge unit axially in relation to and radially in the direction against the outer shaft. whereby the telescopic shaft is prestressed. The prestress mechanism is arranged to release the prestress when the alteration in length of the telescopic shaft exceeds a predetermined length.
A steering wheel arrangement for a motor vehicle includes a steering column having a first end for cooperation with a steering wheel and a second end for cooperation with a vehicle steering mechanism. The steering wheel arrangement further includes a suspension arrangement for the steering column. The suspension arrangement includes two pivot joints and is pivotally connected to the steering column via a third pivot joint, the first, second and third pivot joints including first, second and third locking arrangements, respectively. The steering wheel arrangement has thus three adjustable pivot points where only one or two of the three pivot joints are adjustable in a first step depressing a foot pedal to a first position and only the remaining of the three pivot joints are adjustable in a second step depressing the foot pedal to a second position which implies that the adjustments can be made in a secure way by the driver during the ride.

The invention relates to a telescopic shaft for vehicles comprising an inner shaft (14) axially movable in an outer shaft (16), where the telescopic shaft (4) comprises at least two rows (35, 37) of balls (36, 38) with at least one ball (36, 38) a row (35, 37) between the inner shaft (14) and the outer shaft (16), where a row (35) of balls (36) is arranged on at least one ball race (40) arranged against the inner shaft (14), where the ball race (40) is wedge shaped on its against the inner shaft (14) facing surface and that the telescopic shaft (4) comprises a prestress mechanism (46) which pushes the ball race (40) along a wedge unit (48) axially in relation to and radially in the direction against the outer shaft (16) whereby the telescopic shaft (48) is prestressed and that the prestress mechanism (46) is arranged to release the prestress when the alteration in length of the telescopic shaft (4) exceeds a predetermined length.
A Steering wheel arrangement (10) for a motor vehicle, comprises a steering column (12) having a first end for cooperation with a steering wheel (14) and a second end for cooperation with a vehicle steering mechanism. The steering wheel arrangement further comprises a suspension arrangement for said steering column (12). The suspension arrangement comprises two pivot joints (18, 22) and is pivotally connected to said steering column (12) via a third pivot joint (24), said first, second and third pivot joints (18, 22, 24) comprising first, second and third locking arrangements (29, 30, 31 ), respectively. The steering wheel arrangement has thus three adjustable pivot points where only one or two of the three pivot joints are adjustable in a first step depressing a foot pedal (32) to a first position and only the remaining of the three pivot joints are adjustable in a second step depressing the foot pedal to a second position which implies that the adjustments can be made in a secure way by the driver during the ride.
