Hold 8, it is ensured that nuts 1 keeps the concentricity with bolt 3, and can be in favor of the phase of ratchet 4 and bolt 3 by bearing 8
To rotation, so that being conducive to the ball 5 in 4 rotation process of ratchet skids off groove 42, keep torque-limiting mechanism effect brighter
It is aobvious.
It is as shown in Figure 1-Figure 3 (in conjunction with Fig. 6 and Fig. 7) in present embodiment, on the bolt 3 radially protruding be provided with
The hexagon head structure 32 that the pressing plate 2 cooperates to drive the pressing plate 2 to rotate with the bolt 3.The hexagon head structure can make
Obtaining bolt 3 rotates pressing plate 2 with bolt 3, and the two is avoided to relatively rotate.
Preferably, the hexagon head structure 32 is provided with two or more, and the hexagon head structure 32 can be in the pressure
It is embedded in when 2 injection molding of plate in the pressing plate 2.By the way that two or more hexagon head structures are arranged, bolt 3 can be effectively prevented
It in rundown process, produces relative rotation between pressing plate and bolt 3, while preventing from occurring between pressing plate and bolt 3 in rundown process
It falls off, improves the reliability of assembly.
In present embodiment, the bolt 3 also radially protruding is provided with so that the relatively described pressing plate 2 of the bolt 3 is axial
The positioning ring 33 of positioning.The positioning ring 33 is located at the side departing from radial flange 31 of hexagon head structure 32, the positioning ring
33 play positioning during the pressing plate 2 is with 3 integrated injection molding of bolt.
In present embodiment, the specific structure of pressing plate 2 is as shown in Figure 4 and Figure 5, is arranged on the top surface of the pressing plate 2 useful
It can be manually rotated portion 21 in the rotation pressing plate 2.This can be manually rotated portion 21 and is set as the shape for having the convenience of multiple teeth hand-held,
Centre forms recessed portion 22 to accommodate nuts 1, and it is too high can to protrude pressing plate 2 to avoid nuts 1.It can by can be manually rotated portion 2
The pressing plate 2, easy disassembly are rotated to facilitate.It is understood that can be manually rotated portion 21 can be set to that rotation can be facilitated to press
The other structures form of plate 2.
The bottom center position of pressing plate 2 is formed with recess portion 23, and multiple add circumferentially is arranged at intervals in the recess portion 23
Strengthening tendons 24；Wherein the reinforcing rib 24 is set as generating avoiding space in the centre of the pressing plate 2, as shown in Figure 5
, each reinforcing rib 24 is bent to form generally L-shaped structure leaving at the certain position of centre, this each reinforcing rib 24
It can be avoided at the radially inward position in bending place, for the support bracket fastened top of installation spare tyre can be extend into
In the recess portion 23, the bottom of pressing plate 2 and fixed bracket is avoided to generate interference, is conducive to the hardware and software platform benefit of the spare tyre bolt assembly
With.
In addition, the end far from 2 center of pressing plate in the reinforcing rib 24 is provided with for being positioned at the spare tyre
Bulge-structure 241 of the centre bore to prevent the spare tyre from radially shaking；The bulge-structure 241 is specifically the remote of reinforcing rib 241
The part for protruding from 2 bottom surface of pressing plate that the position at 2 center of tripping plate is bent to form.In the fixed spare tyre of the spare tyre bolt assembly,
The bulge-structure 241 of multiple reinforcing rib 24 is circumferentially positioned in the edge of the centre bore of spare tyre, can prevent spare tyre from radially shaking
It is dynamic.
The lower support bracket fastened detailed process that spare tyre is fixed on to vehicle using the spare tyre bolt assembly is described below.
Spare tyre is covered on fixed bracket first, then the pressing plate 2 of the spare tyre bolt assembly is pressed in the center hole edge of spare tyre
On edge；
The nuts 1 of rotating spare tyre bolt assembly, the torque on nuts 1 are transferred to bolt 3 by torque-limiting mechanism,
Bolt 3 can be screwed on the fixed bracket.In 1 rotation process of nuts, since the rotation of ratchet 4 applies ball 5
Power groove 42 that ball 5 can be made to have along place the trend that moves of inclined-plane 421, when the torque being applied on nuts 1
When no more than preset value, since elastic element 7 applies pretightning force to ball 5, ball 5 is maintained in groove 42, in this way, nuts
The rotation of 1 drive ratchet 4 can drive bolt 3 to rotate by the ball 5 being stuck in card slot 311；And works as and be applied to nuts 1
On torque when being more than preset value, elastic element 7 deforms, and the rotation of 5 ratchet 4 of ball overcomes elasticity first the power that ball 5 applies
The power of part 7 and make ball 5 move along the inclined-plane of groove 42 421 and deviate from groove 42, the rotation of such ratchet 4 cannot pass through
Ball 5 drives bolt 3 to rotate, i.e., torque-limiting mechanism disconnects transmitting of the torque to bolt 3, between nuts 1 and bolt 3
Rotation will appear skidding.
Wherein, the preset value of the torque need to be configured to guarantee fastening of the bolt on fixed bracket.In this way,
When the torque being applied on nuts 1 is more than the preset value, i.e., when nuts 1 skids with respect to bolt 3, then it represents that bolt 3
Have rotated to position, it is ensured that the fixation of bolt 3.
After the bolt 3 is rotated in place, the bulge-structure 241 on the reinforcing rib 24 of 2 bottom of pressing plate is positioned at spare tyre
Centre bore can prevent spare tyre from radially shaking.
It will be appreciated by persons skilled in the art that the torque-limiting mechanism is not limited in present embodiment by setting
The structure type of ratchet 4, ball 5 and card slot 311 etc. is set, others can be disconnected when the torque is more than certain value to be turned
The structure of square transmitting.For example, in another embodiment, can be arranged on the inner wall of the accommodating cavity of nuts 1
One friction member, setting and mutually matched second friction member of first friction member on the outer surface of bolt, revolves in nuts 1
During turning, bolt 3 is driven to rotate by the friction between the first friction member and the second friction member, the power on nuts 1
When square is more than a certain range, the first friction member can produce relative rotation with the second friction member, i.e., produce between nuts 1 and bolt 3
It is raw to skid.Also for example in a further embodiment, card slot can be set on the outer wall of bolt 3, in the accommodating cavity of nuts 1
Ball is set on 11 inner wall, and the direction applied to ball towards the card slot of bolt 3 is set on the inner wall of nuts 1
Pretightning force spring so that ball is secured in card slot, when the torque on nuts 1 is more than a certain range, ball meeting
Deviate from card slot to which nuts 1 and bolt 3 generate skidding.
Another aspect according to the present utility model, also provides a kind of vehicle, and the vehicle includes for fixing consolidating for spare tyre
Fixed rack, the spare tyre and spare tyre bolt assembly as described above covered on the fixed bracket, the spare tyre pass through described standby
Tire bolt assembly is fixed on the fixed bracket.
Preferred embodiments of the present invention, still, the utility model and unlimited are described in detail in conjunction with attached drawing above
In this.In the range of the technology design of the utility model, a variety of simple variants can be carried out to the technical solution of the utility model,
It is combined in any suitable manner including each particular technique feature.In order to avoid unnecessary repetition, the utility model
To various combinations of possible ways, no further explanation will be given.But these simple variants and combination equally should be considered as the utility model institute
