Abstract
The utility model discloses a steering intermediate shaft with flexible connection and aims at providing the steering intermediate shaft which can overcome the deficiency that abnormal sound is produced by an assembly clearance of rigid connection of the steering intermediate shaft in the prior art. The steering intermediate shaft comprises a universal joint and a joint fork pipe, wherein the connection between the universal joint and the joint fork pipe is of the rigid connection, and a rubber cushioning block is arranged at the joint between the joint fork pipe and the universal joint. The steering intermediate shaft disclosed by the utility model mainly aims at eliminating the abnormal sound, reducing production control requirements, reducing the scrappage and reducing the cost.
Description
Technical field
The utility model relates to a kind of tween drive shaft that turns to, especially relate to a kind of flexibly connect turn to tween drive shaft.
Background technology
People require to increase day by day to car comfort now, are rigidly connected owing to turn to adopt between tween drive shaft and the steering column (or deflector), turn to being rigidly connected of tween drive shaft, and each is rigidly connected and must adopts free-running fit.Assembly clearance just appears simultaneously; Steering wheel rotation just can produce and turn to abnormal sound when the assembly clearance at every place stacked up to a certain degree; Some abnormal sound just shows when car load assembles; Some abnormal sound then shows after the client uses certain hour, if the production control precision is not enough, just can produce certain tolerance clearance.Therefore, be usually can occur at driver's steering wheel rotation from the noise that turns to tween drive shaft, make driver and passenger feel uncomfortable, even produce panic sense.
Chinese patent Granted publication number: CN201989841U on September 28 2011 Granted publication day, discloses a kind of tween drive shaft that turns to; Comprise the joint fork shaft and save fork shaft down; Two joint fork shafts are inner, and the outer end is fixed with universal-joint respectively through the spline connection, and the inner is fixed with clamping structure and clip; This tween drive shaft that turns to can avoid making the transition tween drive shaft because of the spacious and abnormal sound of spline wearing and tearing generation pine, but this abnormal sound that turns to tween drive shaft can not eliminate and produce because of rigidly connected assembly clearance.
The utility model content
The utility model is for the rigidly connected assembly clearance of tween drive shaft that turns to that overcomes prior art produces the deficiency of abnormal sound, provide a kind of flexibly connect turn to tween drive shaft.
To achieve these goals, the utility model adopts following technical scheme:
The utility model a kind of flexibly connects turns to tween drive shaft, comprises universal-joint and joint breeches pipe, and being connected between said universal-joint and joint breeches pipe is rigidly connected, and is provided with damping rubber block in the junction of said joint breeches pipe and universal-joint.Increase damping rubber block at middle joint fork place, can eliminate because the assembly clearance that the production precision that is rigidly connected causes inadequately.So just, can eliminate from the noise that turns to tween drive shaft, reduce the production control requirement simultaneously, reduce product rejection rate, save production cost.Can remedy the gap increase that in the bearing circle rotation process, causes through the stiffness characteristics of damping rubber block, actv. control and adjusting gap
As preferably, said damping rubber block is an annular, and with universal-joint and joint breeches pipe interference fit.Circularize convenient for productionly, interference fit then can be eliminated the assembly clearance here, can reduce the tolerance clearance requirement at other place that is rigidly connected, and just can realize through normal production control process, saves production cost.
As preferably, said damping rubber block is imperfect annular, for being the damping rubber block that " X " shape distributes.Being " X " shape can satisfy the requirement of eliminating abnormal sound and saved material, cost-cutting simultaneously.
As preferably, said damping rubber block cross-sectional plane is horizontal " U " shape.Cross-sectional plane can better play buffer action for the damping rubber block of horizontal " U " shape.
Therefore, the utlity model has following beneficial effect: abnormal sound is eliminated in (1); (2) reduce the production control requirement; (3) reduce condemnation factor, practice thrift cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the damping rubber block front view of the utility model.
Fig. 3 is the section drawing of the utility model damping rubber block.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further description.
Embodiment 1
In Fig. 1, embodiment shown in Figure 3, a kind of flexibly connect turn to tween drive shaft, comprise universal-joint 1 and joint breeches pipe 2, being connected to of 2 of universal-joint 1 and joint breeches pipes is rigidly connected, and is provided with damping rubber block 3 at joint breeches pipe 2 with the universal-joint junction.Damping rubber block 3 is an annular, and with universal-joint 1 and joint breeches pipe 2 interference fit.Damping rubber block 3 with arround fit tightly, not only eliminated the assembly clearance at this place, can also weaken the requirement of two place's assembly clearances on the universal-joint, thereby reach the purpose of saving cost.As shown in Figure 3, damping rubber block 3 cross-sectional planes are horizontal " U " shape.This Cross-section Design can well absorb the horizontal extruding of joint breeches pipe 2, buffering effect better and its compare solid construction and saved material.
Embodiment 2
Among the embodiment as shown in Figure 1, a kind of flexibly connect turn to tween drive shaft, comprise universal-joint 1 and joint breeches pipe 2, being connected to of 2 of universal-joint 1 and joint breeches pipes is rigidly connected, and is provided with damping rubber block 3 at joint breeches pipe 2 with the universal-joint junction.As shown in Figure 3, damping rubber block 3 cross-sectional planes are horizontal " U " shape.This Cross-section Design can well absorb the horizontal extruding of joint breeches pipe 2, buffering effect better and its compare solid construction and saved material.
Claims (4)
- One kind flexibly connect turn to tween drive shaft, comprise universal-joint and joint breeches pipe, being connected between said universal-joint and joint breeches pipe is rigidly connected, and it is characterized in that, is provided with damping rubber block in the junction of said joint breeches pipe and universal-joint.
- 2. according to claim 1 a kind of flexibly connect turn to tween drive shaft, it is characterized in that said damping rubber block is an annular, and with universal-joint and joint breeches pipe interference fit.
