Abstract
The utility model relates to a shock-absorbing device for automobile steering columns, which comprises an output column 3 and an input mandrel 2, wherein input mandrel is inserted into the output column, interconnected elastic bodies 1 are provided between the output column and the input mandrel. The utility model is characterized in that: end of the input mandrel is provided with a cylindrical rabbet 2a with a chamfered edge; a round-hole mortise 3a with a chamfered edge that matches with the rabbet is provided at end of the output column; the rabbet of the input mandrel and the mortise of the output column are in clearance fit. The utility model has the advantages of: 1. The steering input mandrel is connected with the steering output column through elastic bodies, and when the vehicle runs in straight motions when the impact is small, turn the steering wheel, and deformation of the elastic rubber alone can drive the steering mechanism, which can reduce impact from the road surface; 2. Joint of the steering input mandrel and the steering output column applies clearance fit between the homocentric cylindrical and edge-chamfered rabbet and mortise, and when the steering wheel is turned manually with a large force (or rapidly), the utility model can prevent deformation of the elastic rubber to achieve direct contact between the input mandrel end and the output column end, thus the flexible transmission is changed into rigid transmission to improve the response to the steering system.
Description
Technical field:
The utility model relates to a kind of auto parts and components, particularly a kind of automobile steering pipe string shock-absorbing device.
Background technology:
Adopt tubing and axial workpiece to pass through spline fitted at present between part Vehicular turn tubing string and the deflector, advanced technologies such as injection moulding and made both positive connection, because this kind connection is a rigid attachment, so chaufeur is in long-duration driving vehicle process, the impact that the road surface is transmitted is directly delivered on the bearing circle by steering swivel system, and high-frequency vibration easily causes driver fatigue; Adopt the bigger rubber elastomeric material of rigidity to connect on some vehicles, can weaken the impact transmitted on the road surface influence to chaufeur, but there is not scheme preferably, cause turning to followability relatively poor, the contriver of present patent application in the motor turning R﹠D work for many years, based on understanding to power steering system, be subjected to the structure such as input shaft, knob bar, valve pocket, miniature gears in the power steering and the inspiration of principle of work, the damper mechanism of steering column tween drive shaft has been carried out deep research.But extensively retrieve at the problems referred to above, still find no desirable technical scheme.
The utility model content:
The purpose of this utility model be exactly for overcome exist in the prior art cause the steering swivel system response relatively slow because of increasing the steering column shock absorption device, turn to the relatively poor shortcoming of followability, and a kind of later-model automobile steering pipe string shock-absorbing device that proposes.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of automobile steering pipe string shock-absorbing device, it is made up of output tubing string and input mandrel, the input mandrel inserts in the output tubing string, be provided with interconnective elastic body between them, it is characterized in that importing the mandrel end and be provided with tenon, the delivery pipe column end is provided with the mortise that matches, and is free-running fit between the mortise of the tenon of input mandrel and output tubing string.
Described tenon, mortise can adopt the single tenon that is formed by the cylinder chamfered edge of free-running fit and form single mortise by the circular hole chamfered edge, also can be polygon tenon that forms by cylindrical chamfered edge and the polygon mortise that forms by the circular hole chamfered edge, as triangle, quadrangle, criss-cross.
Described tenon, mortise also can be separately positioned on the end of delivery pipe column end and input mandrel, and the effect that they play is identical.
In order to reduce vibration and under normal circumstances to turn to, on the input mandrel, be provided with spring-backed quill, spring-backed quill is the interference swelling with input mandrel and delivery pipe intercolumniation and cooperates.
The utility model advantage is: 1, turn to the input mandrel to link to each other with turning to the output tubing string by elastic body, when the vehicle straight-line travelling runs into less impact, during steering wheel rotation, by the distortion of elastomer rubber, just can drive steering hardware, weaken the impact that brings by the road surface; 2, turn to the input mandrel to adopt by the tenon of concentric column chamfered edge, the free-running fit of mortise with turning to output tubing string junction, human is (or fast) when beating direction more energetically, overcome the distortion of elastomer rubber, thereby make input core shaft end and delivery pipe styletable direct contact, flexible transmission becomes positive drive, has improved the response of steering swivel system.
For the utility model is described in further detail, three embodiment of the present utility model are provided below.
Description of drawings:
Fig. 1 is a basic structure scheme drawing of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1;
Fig. 4 is a kind of distressed structure figure (criss-cross) of Fig. 2;
Fig. 5 is the another kind of distressed structure figure (triangle) of Fig. 2.
The specific embodiment:
Embodiment 1: as shown in Figure 1, output is provided with endoporus 3b in the tubing string 3, the left part is provided with link slot 3c, is provided with single mortise 3a of chamfered edge between hole 3b and the link slot 3c.Columniform input mandrel 2, its middle part is connected with the spring-backed quill 1 of cover shape, and spring-backed quill can adopt ternary ethylene rubber (EPDM), and spring-backed quill 1 is all interference fit closely with input mandrel 2 and output tubing string endoporus 3b, and its mated condition is as shown in Figure 3; The left end of input mandrel 2 is provided with the single tenon 2a by the cylinder chamfered edge, and single tenon 2a inserts among single mortise 3a and is free-running fit.Working process of the present utility model is as follows: when vehicle straight-line travelling process runs on the uneven road surface, ground-surface impact is sent on the shock attenuation unit of the present utility model by steering gear, because the distortion of elastic body 1 wherein, thereby weakened high-frequency vibration effectively, the people is subtle to high frequency, the weak vibration of ground feedback, and the traveling comfort of driving is proud to be satisfied; When human (or fast) when beating direction more energetically, act on making every effort to overcome of bearing circle and obeyed the distortion of rubber, thereby make input mandrel 2 rotate angle c around output tubing string 3, the face of cylinder of their chamfered edge produces rigidity with the circular hole face and contacts, be Fig. 2 shown in, input mandrel 2 drive output tubing strings 3 and directly rotation (elastic body 1 of this moment still works, but do not change) with the variation of beating direction power, the input mandrel 2 of this moment is connected with output tubing string 3 perfect rigidities, improve the steering swivel system response, improved the followability of steering swivel system.
Embodiment 2: the criss-cross mortise 3a1 that single tenon among the embodiment 1 and the single mortise that matches also can adopt criss-cross tenon 2a1 as shown in Figure 4 and match, they mainly produce the moment of torsion that rigidity contacts the direction of transfer dish by the side of cross tenon.
Embodiment 3: the triangle mortise 3a2 that single tenon among the embodiment 1 and the single mortise that matches also can adopt triangle tenon 2a2 as shown in Figure 5 and match, mainly by the face of cylinder of triangle tenon, mortise, perhaps the side produces the moment of torsion that rigidity contacts the direction of transfer dish for they.
