Description
Technical field
The utility model relates to a kind of parts of automobile steering system, is specifically related to a kind of ball-type car steering tube column tween drive shaft member.
Background technology
During motor turning, need to transmit steering torque by steering column, ball-type car steering tube column can transmit larger moment of torsion.As shown in Figures 1 to 4, existing ball-type car steering tube column tween drive shaft member comprises mandrel sleeve pipe 1, some steel balls 2 and mandrel 3, mandrel sleeve pipe 1 and mandrel 3 interference fit, the inwall of mandrel sleeve pipe 1 is provided with three the first steel ball mounting grooves 11 vertically, the outer wall of mandrel 3 is provided with three the second steel ball mounting grooves 31 vertically, three the first steel ball mounting grooves 11 and three the second steel ball mounting grooves 31 are arranged in the space of the first steel ball mounting groove 11 and the second steel ball mounting groove 31 formation over against, some steel balls 2 clampings one by one.It can transmit larger moment of torsion, but but there are the following problems: in (1) steering procedure, the first steel ball mounting groove and the second steel ball mounting groove be easily wearing and tearing under high pulling torque effect, in the space that steel ball easily forms with the second steel ball mounting groove at the first steel ball mounting groove, there is loosening (being that steel ball occurs gap with coordinating of the first steel ball mounting groove, the second steel ball mounting groove), cause moment of torsion transmission efficiency to decline; (2) long-term high pulling torque effect makes mandrel and mandrel sleeve pipe quick abrasion, needs integral replacing mandrel and mandrel sleeve pipe after wearing and tearing, and replacement cost is high.
Summary of the invention
The purpose of this utility model is to provide a kind of ball-type car steering tube column tween drive shaft member, to reduce to rotate the wearing and tearing that produce, improves steering torque transmission efficiency, reduces replacement cost simultaneously.
Ball-type car steering tube column tween drive shaft member described in the utility model, comprise mandrel sleeve pipe, steel ball and mandrel, described mandrel sleeve pipe coordinates with mandrel, the inwall of described mandrel sleeve pipe is provided with a plurality of the first steel ball mounting grooves vertically, the outer wall of described mandrel is provided with a plurality of the second steel ball mounting grooves vertically, and a plurality of the first steel ball mounting grooves and a plurality of the second steel ball mounting groove one by one over against, in described the second steel ball mounting groove, be provided with elastic card, in the space of elastic card and the formation of the first steel ball mounting groove, be provided with the described steel balls of some grains.
The section of described elastic card takes the shape of the letter U suitable with the shape of the second steel ball mounting groove, the bottom surface of the bottom surface of described elastic card and the second steel ball mounting groove against the dual-side outward of, described elastic card form with the sidewall of the second steel ball mounting groove against elasticity flanging.
The inwall of described mandrel sleeve pipe is provided with three the first steel ball mounting grooves vertically, and the outer wall of described mandrel is provided with three the second steel ball mounting grooves vertically, and three the first steel ball mounting grooves and three the second steel ball mounting grooves one by one over against.
While turning to, mandrel is subject to steering torque effect, drive steel ball that power is passed to elastic card, the stressed rear formation elastic force of two elasticity flangings is pressed on steel ball in the space of elastic card and the formation of the first steel ball mounting groove, and steel ball passes to mandrel sleeve pipe by moment of torsion, transmission efficiency is high, because elastic card has elasticity, and in design process, can choose according to the size of transmitting torque the elastic card of different-stiffness, therefore it can guarantee that steel ball is pushed against all the time, thereby reduce the tolerance clearance that (or elimination) occurs.
The utility model adopts elastic card to coordinate with the second steel ball mounting groove, the first steel ball mounting groove, the gap that elastic card can compensate for wear brings, and raising moment of torsion transmission efficiency, and its wearing and tearing to mandrel while also having reduced torque drive, extended mandrel service life; Excessive need to change steering column tween drive shaft time if worn and torn, only need to change mandrel sleeve pipe and the elastic card of wearing and tearing, do not need to change mandrel, reduced replacement cost.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
Ball-type car steering tube column tween drive shaft member as shown in Figures 5 to 9, comprise mandrel sleeve pipe 1, steel ball 2 and mandrel 3, steel ball 2 has 18, and (the several moments of torsion that transmit according to tween drive shaft of concrete grain of steel ball are determined, because the torsion transmitting is larger, groove is longer, the steel ball needing is more), the inwall of mandrel sleeve pipe 1 is provided with three the first steel ball mounting grooves 11 vertically, the outer wall of mandrel 3 is provided with three the second steel ball mounting grooves 31 vertically, in each second steel ball mounting groove 31, be provided with an elastic card 4, the section of elastic card 4 takes the shape of the letter U and matches with the shape of the second steel ball mounting groove 31, the bottom surface 42 of elastic card 4 and the bottom surface of the second steel ball mounting groove 31 against, the dual-side outward of elastic card 4 form with the sidewall of the second steel ball mounting groove 31 against elasticity flanging 41, mandrel sleeve pipe 1 and mandrel 3 interference fit, three the first steel ball mounting grooves 11 and three the second steel ball mounting grooves 31 one by one over against, 18 steel ball 2 clampings are arranged in three spaces of three elastic cards 4 and three the first steel ball mounting groove 11 formation, 6 steel balls of card in each space, the length of each elastic card 4 is identical with the length that 6 steel balls, 2 clampings are arranged.
Elastic card 4 is inlaid in the second steel ball mounting groove 31, mandrel sleeve pipe 1 is sleeved on mandrel 3 and mandrel 3 interference fit, steel ball 2 is arranged clamping and is arranged in the space of elastic card 4 and the first steel ball mounting groove 11 formation, the two side of two elasticity flangings 41 and the second steel ball mounting groove 31 compresses, the bottom surface of the bottom surface 42 of elastic card and the second steel ball mounting groove 31 compresses, while turning to, mandrel 3 is subject to steering torque effect, drive steel ball 2 that power is passed to elastic card 4, two elasticity flangings 41 form elastic force and compress steel ball 2 by elastic card inwall 43, mandrel 3 passes to mandrel sleeve pipe 1 by steel ball 2 by moment of torsion.As shown in Fig. 6, Fig. 7, Fig. 8, conter clockwise torsional interaction if, the elasticity flanging 41 of F side is subject to force compresses, and the elasticity flanging 41 of E side extends, thereby compresses steel ball 2.In steering procedure, steel ball 2 remains with elastic card inwall 43 the flush fit state that contacts with the bottom surface 42 of elastic card, and it can reduce the tolerance clearance that (or elimination) causes due to wearing and tearing, thereby improves steering torque transmission efficiency.
