Description
Technical field
The utility model belongs to the car technical field, specifically, particularly on car, turns to the dust protecting cap hermetically-sealed construction.
Background technology
Steering wheel is arranged in the machinery space of car, and the via hole on vehicle body sheet metal is passed in the upper end of this steering wheel input shaft, and stretches in operator's compartment, in order to be connected with bearing circle.At present, in the via hole passed through for the steering wheel input shaft at vehicle body sheet metal, operated by rotary motion turns to dust protecting cap, enters operator's compartment to prevent the dust in machinery space, and reduces to pass to from machinery space the noise of operator's compartment.Existing dust protecting cap is comprised of metal collar and rubber coating two parts, the metal collar is embedded in rubber coating by the distortion of rubber, two parts are formed a whole, and vehicle body sheet metal embeds between the upper port and metal collar of rubber coating, by the metal collar, rubber coating is fixed on vehicle body sheet metal.The existing deficiency of above structure is:
1) due to metal collar and rubber sandwich panel beating, can make to produce gap between machinery space and operator's compartment, sealing property is bad like this, can cause soundproof effect poor, and produces the leakage sound.
2) the metal collar is not easy to install, and fitting operation is loaded down with trivial details on the one hand, and efficiency of assembling is not high; On the other hand, the fixing of installation is poor, and the metal collar easily comes off.
The utility model content
What technical problem to be solved in the utility model was to provide a kind of good airproof performance turns to the dust protecting cap hermetically-sealed construction.
The technical solution of the utility model is as follows: a kind of dust protecting cap hermetically-sealed construction that turns to, comprise dust protecting cap (1), steering wheel input shaft (2), vehicle body sheet metal (3) and steering wheel housing (4), wear steering wheel input shaft (2) in described steering wheel housing (4), vehicle body sheet metal (3) is provided with the via hole passed for steering wheel input shaft (2) upper end, and at the outside ring set of steering wheel input shaft (2), dust protecting cap (1) is arranged, described dust protecting cap (1) is made by rubber, the lower end of this dust protecting cap (1) is placed on steering wheel housing (4) admittedly, the upper end of dust protecting cap (1) is through the via hole on vehicle body sheet metal (3), and between dust protecting cap (1) and vehicle body sheet metal (3), clamping coordinates.
The utility model is changed into the steering wheel housing by dust protecting cap and directly is connected by rubber deformation by traditional rubber coating+metal collar with the connection mode between vehicle body sheet metal, there is no gap in junction so on the one hand, good airproof performance, soundproof effect is good, can effectively prevent the leak-stopping sound; On the other hand, install and not only facilitate but also quick, and the fixing connected is good, can not occur loosening or come off.Simultaneously, owing to having reduced the metal collar, simplify mounting structure, effectively reduced productive costs.
Described dust protecting cap (1) is comprised of the annular boss (1a) of upper end, the conulite (1b) at middle part and the cylindrical shell (1c) of lower end, described cylindrical shell (1c) is placed on steering wheel housing (4) admittedly, (1b) is up big and down small for described conulite, the end face of this conulite (1b) and vehicle body sheet metal (3) fit, described annular boss (1a) is upward through the via hole on vehicle body sheet metal (3), be provided with annular slot between annular boss (1a) and conulite (1b), this annular slot coordinates with described vehicle body sheet metal (3) clamping.Above structure dust protecting cap moulding on the one hand is simple, is easy to processing and fabricating and assembling; On the other hand, dust protecting cap engages with vehicle body sheet metal closely, can further guarantee the fastness and the reliability that connect, effectively to prevent loosening or gap, produces.
The end face of described annular boss (1a) is circular conical surface, and this circular conical surface through playing guiding in the vehicle body sheet metal via hole and reducing resistance, makes the assembling of dust protecting cap more laborsaving at annular boss, convenient, fast.
As preferably, be formed with a circle fin on the inwall of described cylindrical shell (1c), this fin embeds in the annular groove on steering wheel housing (4) outer wall.Above structure can further strengthen the fixing that is connected between dust protecting cap and steering wheel housing, to prevent dust protecting cap, from the steering wheel housing, occurs loosening or comes off.
Beneficial effect: the utility model has guaranteed between machinery space and operator's compartment the sealing property at steering wheel input shaft place on the one hand, thereby has effectively prevented that the leakage sound from producing; On the other hand, dust protecting cap is easy for installation, quick, and fixing is good, is difficult for loosening or comes off.The utlity model has the characteristics such as design is ingenious, simple in structure, good reliability, transformation is easy, improvement cost is low, can be suitable on various types of cars.
