The embodiment stated is exemplary, and is only used for explaining the present invention, and is not construed as limiting the claims.
As shown in Figures 1 to 8, length-adjustable steering drive axle component provided in an embodiment of the present invention, including the first biography
Moving axis 10, second driving shaft 20 and elastic torsion ring 30.Wherein, Fig. 1 show partly cut-away, it is seen that the axis of internal structure is surveyed
Figure.
Wherein, one end of the first transmission shaft 10 offers axial hole 11；Axial hole 11 is inserted into one end of second driving shaft 20
In, and can hole 11 in an axial direction axial movement；The outer ring of elastic torsion ring 30 is embedded in axial hole 11, elastic torsion ring 30
Inner ring fixing sleeve is set on second driving shaft 20.
When assembly, the other end of the first transmission shaft 10 is connected to steering by a universal joint and a rigid axial rod
On disk, the other end of second driving shaft 20 is connected to by a universal joint in steering gear.
Length-adjustable steering drive axle component provided in an embodiment of the present invention, second driving shaft 20 are connected to the first transmission
It in the axial hole 11 of axis 10, and can be moved along the axial direction of the axial hole 11, to change entire steering transmission group
The length of part.Specifically, please with the direction in Fig. 2 to refer to, when second driving shaft 20 moves right, entire steering drive axle group
Part shortens；On the contrary, when second driving shaft 20 is moved to the left, entire steering drive axle component elongation.
Length-adjustable steering drive axle component provided in an embodiment of the present invention, it is whole without fastenings such as bolt and nuts
Part is attached, easy to assembly, reduces the overall volume of steering drive axle component, reduces assembly difficulty, while can also
Ensure torque reliable delivery, and elastic torsion ring 30 plays sealing function, and external foreign matter is avoided to enter in axial hole 11.
Further, it please refers to Fig.1 and Fig. 6, offers mounting groove 21 on second driving shaft 20, be equipped in mounting groove 21
Sliding block 40；Sliding block 40 can in an axial direction hole 11 inner wall movement.And preferably, in order to limit sliding block 40, while ensuring to slide
The stability that block 40 slides, offers arc groove 13 on the inner wall of axial hole 11, the axial direction in the hole 11 in an axial direction of arc groove 13
Extend；Arcuately slot 13 moves sliding block 40.When sliding block 40 is installed in arc groove 13, sliding block 40 is also reserved with arc groove 13
Swing gap 14.Preferably, sliding block 40 is small using frictional resistance, and the nylon material manufacture that wearability is strong.
Wherein, the movement by sliding block 40 in arc groove 13, the length that may be implemented to turn to transmission component is adjustable, and
When sliding block 40 slides in arc groove 13, it can be isolated and eliminate axial vibration.Simultaneously because between arc groove 13 and sliding block 40
It is reserved with and swings gap 14, sliding block 40 and second driving shaft 20 can rotate by a certain angle relative to the first transmission shaft 10 jointly.
When second driving shaft 20 twists vibration, since elastic torsion ring 30 and the fixation of second driving shaft 20 are arranged, the two
Between relative rotation cannot occur；The 10 radially secure connection of elastic torsion ring 30 and the first transmission shaft, therefore therebetween
Relative rotation cannot occur；So when second driving shaft 20 twists vibration, the both ends of elastic torsion ring 30 generate relatively
Torsion, it is to be understood that a small amount of relative rotations also occurs for the first transmission shaft 10 and second driving shaft 20 at this time, when torsion is shaken
After dynamic disappearance, elastic torsion ring 30 is sprung back, and the first transmission shaft 10 and second driving shaft 20 is driven to be restored to initial position；Sliding block 40
Initial position is also returned to, to realize the flexible connection between the first transmission shaft 10 and second driving shaft 20, is isolated and disappears
In addition to the twisting vibration between the first transmission shaft 10 and second driving shaft 20.
When needing to turn to, driver applies steering torque by the first transmission shaft of steering wheel pair 10, first so that elasticity
Torsion ring 30 is reversed, and the first transmission shaft 10 and second driving shaft 20 generate a small amount of relative rotations, sliding block 40 and arc groove 13
Side wall surface contacts so that rigid connection is formed between the first transmission shaft 10 and second driving shaft 20, by steering torque smoothly from the
One transmission shaft 10 is transferred to second driving shaft 20, and is transferred to steering gear by second driving shaft 20, is turned to realize.
Specifically, the first transmission shaft 10 and elastic torsion ring 30 connect in the following manner, and second driving shaft 20 includes six
The inner ring of side shape section 22, elastic torsion ring 30 is hexagon, and the inner ring of elastic torsion ring 30 is sheathed in the section of six sides.Hexagon section
22 and elastic torsion ring 30 hexagon inner ring, ensure not will produce opposite turn between the first transmission shaft 10 and elastic torsion ring 30
It is dynamic, and without fasteners such as bolts, it is convenient and simple.To increase structural stability, limitation elastic torsion ring 30 and second passes
The inner ring of axial movement between moving axis 20, elastic torsion ring 30 is additionally provided with limit protrusion 31, is arranged on second driving shaft 20
There are limiting slot 23, limit protrusion 31 to be matched with limiting slot 23.
It is fixedly connected in the following manner between second driving shaft 20 and elastic torsion ring 30, the outer ring of elastic torsion ring 30
It is provided with arc convex 32, arc convex 32 is matched with arc groove 13.The arc convex 32 is connected in arc groove 13, to
It relatively rotates between limitation second driving shaft 20 and elastic torsion ring 30, it is ensured that the reliability of flexible connection, and without adopting
It is simple in structure with fasteners such as bolts, it is easy to use.
Preferably, it is provided with faulted joint 33 on elastic torsion ring 30.The faulted joint 33 is convenient for 30 sets of the elastic torsion ring
On second driving shaft 20.
Further, it is provided with annular slot 12 on the inner wall of axial hole 11；The embodiment of the invention also includes elastic spacings
Ring 50, elastic spacing ring 50 are installed in annular slot 12, and are sheathed on second driving shaft 20, which is to open
Choma, opening are provided at both ends with aduncate crotch, which ensures that elastic spacing ring 50 is installed in annular slot 12
When, it is not easy to loosen.The elastic spacing ring 50 is set in side of the second driving shaft 20 far from the first transmission shaft 10, please refers to attached drawing
