Description
Technical field
The utility model relates to the technical field of racing car components structure, is specially a kind of bearing circle quick-disassembly structure.
Background technology
Due to racing car, be subject to laws of the game and other restriction, the operator's compartment of racing car closely, its cab space is very limited, under the restriction of a series of condition, the bearing circle of racing car can only make detouchable, and chaufeur is when passing in and out operator's compartment, first pull down bearing circle, after chaufeur is occupied stably, bearing circle is being installed, first bearing circle being pulled down when leaving operator's compartment, flowing out enough cab space, ensure speeding away of chaufeur, ensure that chaufeur rapid escape in case of emergency.
Bearing circle quick-disassembly structure achieves when bearing circle is installed in driving procedure and is connected with S. A., meets the manipulation of chaufeur to racing car direction, when chaufeur leaves operator's compartment, bearing circle is simple, pulls down rapidly.Existing bearing circle quick-disassembly structure, if the patent No. is the Chinese utility model patent of ZL2012202691369, its outer ring inwall is connected by the invoice serration that cooperatively interacts with interior ring outer wall, transmitting torque is carried out by invoice serration, due to bearing circle rotate frequency and larger torsion to be produced in rotary course, invoice serration can produce wearing and tearing, makes outer ring occur relative swing offset with inner ring, thus have impact on the stable of bearing circle rotation, also can cause the accident time serious.
Summary of the invention
For the problems referred to above, the utility model provides a kind of bearing circle quick-disassembly structure, effectively prevent the wearing and tearing of inner ring and outer ring, ensure that outer ring and and inner ring there is the stable of relative position, outer ring is prevented to occur relative swing offset with inner ring, ensure that bearing circle rotates stable, avoid and produce unnecessary accident.
Its technical scheme is such: a kind of bearing circle quick-disassembly structure, comprise outer ring and inner ring, described outer ring is provided with the push rod tank with Axis Cross in eccentric axis position, described push rod tank communicates with the endoporus of outer ring, arrange in described push rod tank and push rod is installed, on described push rod, corresponding described inner ring is provided with yielding groove, the positioning groove coordinated with push rod is provided with outside described inner ring, it is characterized in that: described outer ring inwall is polygon, described interior ring outer wall coordinates with described outer ring inwall.
It is further characterized in that: described outer ring inwall is hexagon; Described outer ring inwall is regular hexagon; Be provided with stage clip in described push rod tank, described stage clip connects described push rod one end, and on described outer ring, corresponding described yielding groove is provided with locating dowel pin.
In said structure of the present utility model, because outer ring inwall is polygon, interior ring outer wall coordinates with outer ring inwall, effectively prevent the wearing and tearing of inner ring and outer ring while ensureing normally to export compared with high pulling torque, ensure that outer ring and and inner ring there is the stable of relative position, prevent outer ring to occur relative swing offset with inner ring, ensure that bearing circle rotates stable, thus avoid the unnecessary accident of generation.
Accompanying drawing explanation
Fig. 1 is the utility model bearing circle quick-disassembly structure schematic diagram;
Fig. 2 is the cross-sectional schematic of bowing of Fig. 1;
Fig. 3 is the left view of Fig. 1.
Detailed description of the invention
See Fig. 1, Fig. 2, Fig. 3, a kind of bearing circle quick-disassembly structure, comprise outer ring 1 and inner ring 2, outer ring 1 inwall is polygon, inner ring 2 outer wall coordinates with the polygon of outer ring 1 inwall, outer ring 1 is provided with the push rod tank 3 with Axis Cross in eccentric axis position, push rod tank 3 communicates with the endoporus of outer ring 1, arrange in push rod tank 3 and push rod 4 is installed, on push rod 4, corresponding inner ring 2 is provided with and makes a concession groove 5, push rod 4 moves, and makes a concession groove 5 and forms accessible outer ring 1 inwall with outer ring 1 inwall, be provided with the positioning groove 6 coordinated with push rod 4 outside inner ring 2.
For preventing outer ring 1 inwall and the cooperation of inner ring 2 outer wall from frequently producing wearing and tearing passivation, polygonal limit number can not be too many, and the present embodiment adopts outer ring inwall to be hexagon, and interior ring outer wall coordinates with outer ring inwall, and in that, ring outer wall is also into hexagon certainly.
Because push rod 4 can rotate, make a concession groove 5 and be arranged to circular groove, make push rod 4 rotate to any angle, all exist between outer ring 1 and push rod 4 and make a concession groove 5.
In order to inwall processing in outer ring easy to process is in regular hexagon.
Be provided with stage clip 7 in push rod tank 3, stage clip 7 connects push rod 4 one end, achieves the self-return of push rod 4, realizes push rod 4 and the engaging of inner ring 2, can certainly adopt and pull out pull bar manually, equally also can realize the engaging of push rod 4 and inner ring 2.
Drop in order to anti-throw-out lever 4 skids off, on outer ring 1, corresponding groove 5 of making a concession is provided with locating dowel pin 8.
The principle of work of the utility model bearing circle quick-disassembly structure is described below in conjunction with Fig. 1, Fig. 2:
Outer ring closure dish, inner ring is connected with deflector by steering shaft:
During installation, promote push rod 4 and move, make a concession groove 5 and form accessible outer ring 1 inwall with outer ring 1 inwall, inner ring 2 is successfully inserted in outer ring 1, pulls push rod 4, and push rod 4 one end snaps in the positioning groove 6 outside inner ring 2, prevent moving axially of inner ring 2, achieve the fast-assembling of bearing circle.During dismounting, promote push rod 4 and move, make a concession groove 5 and form accessible outer ring 1 inwall with outer ring 1 inwall, pull outer ring 1, outer ring 1 is successfully extracted out from inner ring 2, achieves the quick detach of bearing circle.
This bearing circle quick-disassembly structure adopts simple structure, utilizes polygon to carry out transmitting torque, not only reliable operation, and transmitting torque is large, and effectively prevent the wearing and tearing passivation that bearing circle rotates outer ring inwall and the interior ring outer wall caused frequently.
The present embodiment adopts outer ring inwall to be regular hexagon; certain outer ring inwall also can be other polygon; as long as have employed polygon, avoiding the wearing and tearing passivation that bearing circle rotates outer ring inwall and the interior ring outer wall caused frequently, is all protection domain of the present utility model.
