Description
Technical field
The invention belongs to field of automobile, specially refer to the damped noise reduction device of ball-joint assembly in a kind of steering linkage.
Background technology
Passenger car adopts rack and pinion steering gear more at present, this steering gear generally adopts ball-joint assembly and steering gear housing stop collar in pull bar to limit rack stroke at extreme position, and two parts that play position-limiting action in steering gear are metal structure, therefore while contact, can produce the metal strike note of " thud, thud " and the vibrations of steering wheel, this sound and vibrations meeting are delivered to driver's cabin by vehicle body and steering gear itself, make driver's uneasiness that has the fidgets, two metal parts often clash into and can reduce its service life simultaneously, increase maintenance cost. Impact noise when some steering gear meeting at present increases plastic material parts with reduction contact in housing, but because housing section bit space is limited, most steering boxs can not increase unnecessary parts on housing, thereby make to solve metal impact noise and vibration problems becomes bottleneck.
Summary of the invention
The object of the invention is to propose the damped noise reduction device of ball-joint assembly in a kind of steering linkage, to reduce the noise of steering gear, improve the NVH performance of automobile, and extend the service life of steering gear.
According to the damped noise reduction device of ball-joint assembly in steering linkage provided by the invention, comprise interior bulb, interior ball cup, tooth bar, stop collar, described interior ball cup is fixedly connected with tooth bar end, described stop collar is set on tooth bar, key is to be also provided with sleeve between described interior ball cup front end face and described tooth bar terminal surface, described jacket casing, at interior ball cup leading section, is provided with the elastic support structure of spring and packing ring between the front end face of described interior ball cup and the inner face of described sleeve.
The damped noise reduction device of ball-joint assembly in steering linkage of the present invention, by quill being set at interior ball cup and tooth bar junction, one end of quill is enclosed within on interior ball cup, the other end is spacing by tooth bar distal end faces, elastic support structure is set in sleeve again, thereby make the hard collision between ball-joint assembly in pull bar and steering gear housing stop collar into flexible contact, component wear and noise that collision causes are reduced, when steering wheel is got to extreme position in guarantee driver's cabin, can not produce noise, improve the feel of extreme position simultaneously, make driver's mood keep happy.
Specifically, be also provided with pad between described packing ring and spring, described pad is fixed on packing ring, and the contact-making surface of described packing ring and pad is provided with multiple lug bosses, and described lug boss is circumferential arrangement on the contact-making surface of described packing ring or pad. The lug boss arranging on pad or packing ring, both while having ensured that interior ball cup contacts with stop collar stressed evenly, contact area is little, can ensure again the flexible contact of interior ball cup and stop collar, thereby the noise when more reducing steering wheel and getting to extreme position, improves the feel of extreme position.
Concrete, described packing ring inner circle is connected with cannula portion, and the cannula portion of described packing ring and washer face junction are provided with groove, and described pad is connected to the groove of described packing ring. Can ensure that like this pad is not easy displacement or cracked, avoids affecting the effect of damped noise reduction device.
Further, described lug boss is hemispherical protuberances. Described hemispherical protuberances is circumference and uniform gap is arranged on the contact-making surface of described packing ring or pad. Collision area when hemispherical protuberances not only can reduce interior ball cup and contacts with stop collar, and while ensureing collision stressed evenly.
Further, described packing ring is fixed on the inner face of described sleeve, causes wearing and tearing to ensure that packing ring can not rotate or be shifted.
Specifically, the one side that described packing ring contacts with the inner face of described sleeve is provided with clamping protuberance, and the clamping protuberance of described packing ring coordinates with the through hole clamping of described sleeve end face.
Further, described pad and packing ring are plastic material, increase the effect of damping noise reduction.
Brief description of the drawings
Fig. 1 is sectional structure schematic diagram of the present invention.
Fig. 2 is the structure for amplifying schematic diagram of Fig. 1 at A place.
Fig. 3 is the structural representation of hemispherical protuberances of the present invention.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail as effect and the operation principle etc. of the mutual alignment between the shape of related each member, structure, each several part and annexation, each several part.
Embodiment 1:
As Fig. 1, the damped noise reduction device of ball-joint assembly in steering linkage of the present invention, comprise interior bulb 1, interior ball cup 2, tooth bar 3, stop collar 4, interior ball cup 2 is fixedly connected with tooth bar 3 ends, stop collar 4 is set on tooth bar 3, between interior ball cup 2 front end faces and tooth bar terminal surface, be also provided with sleeve 5, sleeve 5 is enclosed within interior ball cup 2 leading sections, is provided with the elastic support structure of spring 6 and packing ring 7 between the front end face of interior ball cup 2 and the inner face of sleeve 5.
Concrete, between packing ring 7 and spring 6, being also provided with pad 8, pad 8 is fixed on packing ring 7, and packing ring 7 is provided with multiple lug bosses with the contact-making surface of pad 8, and lug boss is circumferential arrangement on the contact-making surface of packing ring 7.
