Abstract
The utility model discloses a kind of brake block fastening piece, comprise bolt, packing ring and nut.Described bolt is polygonal flange bolt, is provided with two rings, supporting with nut; The internal diameter of described packing ring is greater than the external diameter of bolt, freely can horizontally slip between the head of bolt and nut.Because packing ring of the present utility model adopts the metal material that thermal expansion coefficient is higher.When braking, due to frictional heat, the packing ring be delivered to by screw rod, thus make washer expansion, and then fastening brake block, achieve and should meet the fastening firm effect meeting auxiliary brake again.
Description
Technical field
The utility model relates to fastening piece, is specifically related to a kind of brake block fastening piece of for traffic tool.
Background technique
In the brake system of automobile, brake block is the breaking piece of most critical, and the quality of all braking effects is all that brake block plays a decisive role, so the brake block of agreeing is the patron saint of people and automobile.And the fastening piece being commonly used to fixing brake block is also most important.Fastening piece is generally made up of screw bolt and nut.Bolt is made up of head and screw rod (with externally threaded cylindrical body) two-part, needs and nut screw connection, for being fastenedly connected the brake block with through hole.
But, so but there are problems, such as brake for a long time, or water met by fastening piece, or fastening piece in the situation such as cold weather, all can be caused to loosen.The safety of driving people will certainly be had influence on like this.
Therefore, urgently propose a kind of brake block fastening piece at present, the fastening firm effect meeting auxiliary brake again should be met.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of brake block fastening piece, comprising:
Bolt, described bolt is polygonal flange bolt, is provided with two rings, and tip to the first ring of described bolt is provided with screw thread;
Packing ring, described packing ring is the metal material that thermal expansion coefficient is higher, and between the head being arranged at the second ring and described bolt, brake block is arranged between described first ring and described second ring, and the distance of described packing ring and brake block is 1 ~ 3mm;
Nut, described nut is round nut, and one end heart is provided with the screw thread with described bolt matching, and the other end heart is provided with the polygonal of depression.
Further, the internal diameter of described packing ring is greater than the external diameter of bolt, can freely horizontally slip between the head and described nut of described bolt.
Further, the other end heart of described nut is provided with the regular hexagon of depression.
Described a kind of brake block fastening piece of the present utility model has the following advantages compared to existing technology:
The distance of described packing ring and brake block is 1 ~ 3mm.When braking, due to frictional heat, being delivered to the high packing ring of thermal expansion coefficient by screw rod, thus making washer expansion, and then fastening brake block.Solve the problem causing brake block braking effect difference because fastening piece loosens.
Accompanying drawing explanation
In order to make content of the present utility model be more likely to be clearly understood, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein,

Fig. 4 is the nut structure schematic diagram of brake block fastening piece described in the utility model;
Fig. 5 is the scheme of installation of brake block fastening piece described in the utility model;
In figure, reference character is expressed as: 1-bolt; 2-packing ring; 3-nut; 4-first ring; 5-second ring.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, mode of execution of the present utility model is described in further detail.
As Figure 1-4, the brake block fastening piece of the present embodiment, comprising:
Bolt 1, described bolt 1 is polygonal flange bolt, is provided with two rings, and tip to the first ring 4 of described bolt 1 is provided with screw thread;
Packing ring 2, described packing ring 2 is the metal material that thermal expansion coefficient is higher, is arranged between the second ring 5 and 1, described bolt, and brake block is arranged between the first ring 4 and the second ring 5, and described packing ring 2 is 2mm with the distance of brake block;
Nut 3, described nut 3 is round nut, and one end heart is provided with the screw thread supporting with described bolt 1, and the other end heart is provided with the regular hexagon of depression.
For realizing the purpose of this utility model, the internal diameter of described packing ring is greater than the external diameter of bolt, can freely horizontally slip between the head and nut of bolt 1.
The working principle of the brake block fastening piece described in the present embodiment is as follows: as shown in Figure 5,
When braking, due to frictional heat, being delivered to the high packing ring of thermal expansion coefficient by screw rod, thus making washer expansion, and then fastening brake block.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And thus the apparent change of extending out or variation be still among protection domain of the present utility model.
