[0024] For a better understanding of the technical solutions of the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0025] As Figure 1-3 shown, a lightweight air disc brake bracket and a brake are provided, including two shoulders 10 and an arch waist 20.
[0026] The two shoulders 10 are symmetrically arranged and have the same structure, and both include a first side shoulder 101, a second side shoulder 102 and a positive shoulder 103. The first side shoulder 101 and the second side shoulder 102 are arranged in parallel and are integrally connected to the two symmetric sides of the positive shoulder 103 respectively.
[0027] The arch waist 20 includes a first side waist 201 and a second side waist 202 arranged in parallel. The two ends of the first side waist 201 and the second side waist 202 are respectively connected to the two shoulders 10, jointly forming an integral structure with a hollow middle part and integrally connected four sides.
[0028] Among them, the first side waist 201 and the second side waist 202 have different structures. The first side waist 201 is a structure with both ends of the middle part expanded. The top surface of the second side waist 202 has a first weight-reducing groove 2021; the positive end surface of the first side shoulder 101 has a second weight-reducing groove 1011 and a third weight-reducing groove 1012, and its top surface has a fourth weight-reducing groove 1013. The top surfaces of the first side shoulder 101 and the second side shoulder 102 both have a fifth weight-reducing groove 1021.
[0029] As Figure 1 and Figure 6 shown, in an embodiment, the top surfaces of the first side shoulder 101 and the second side shoulder 102 are inclined in the direction from the end far away from their connection with the positive shoulder 103 to the end connected to the positive shoulder 103, and the thickness of the outer edge of the top surfaces of the first side shoulder 101 and the second side shoulder 102 is smaller than the thickness of the remaining part.
[0030] As Figure 1 shown, in an embodiment, the positive shoulder 103 is inclined outward from its top surface to the bottom surface.
[0031] It can be understood that through the diagonal design, the force generated by the arch waist 20 can be better transmitted to the shoulder 10. In the laboratory torsion fatigue test, it is proved that although reducing the thickness in this area slightly increases the computer stress analysis, the stress value does not exceed the tensile strength of the cast iron material. Therefore, reducing the thickness does not affect the structure, and the bracket can still meet the design requirements and the weight of the bracket is reduced.
[0032] As Figure 2 shown, in one embodiment, one end of the first weight reduction groove 2021 is a straight edge, and the other end is an arc-shaped edge, and the overall shape is bow-shaped.
[0033] It can be understood that the above treatment is to ensure that the bracket has sufficient fatigue strength to meet the requirements of the braking condition while reasonably weakening the overall structural strength of the bracket, and at the same time reduce the stress in the area with relatively large local stress in the arch waist 20, increasing the safety factor here. It can also avoid too strong rigidity at the middle position of the arch waist 20, which has a negative impact on the local stress of the arch waist 20 during braking.
[0034] As Figure 1 shown, in one embodiment, the second weight reduction groove 1011 has several distributed on the front end face of the first side shoulder 101, and the third weight reduction groove 1012 is arranged at the bottom of the front end face of the first side shoulder 101.
[0035] As Figure 1-3 shown, in one embodiment, the outer edges of the fourth weight reduction groove 1013 and the fifth weight reduction groove 1021 both have arc transitions.
[0036] It can be understood that by adopting an ultra-large arc transition and removing the local material in the useless area, the weight of the bracket can be reduced. In the laboratory torsion fatigue test, it is proved that by appropriately removing the bracket material at this part, the bracket still has sufficient fatigue strength to meet the requirements of the braking condition.
[0037] As Figure 5-6 shown, in one embodiment, the widths of the connections between the top end faces of the first side shoulder 101, the top end faces of the second side shoulder 102 and the positive shoulder 103 are all greater than the widths of the other parts.
[0038] As Figure 6 shown, in one embodiment, there are reinforcing ribs at the connections between the first side shoulder 101, the second side shoulder 102 and the positive shoulder 103.
[0039] It can be understood that the above treatment is to locally add material to the bracket material, add reinforcing ribs in appropriate areas where the stress is relatively large, and better conduct the force to the shoulder 10 area by means of large and small grooves and adding reinforcing ribs. Through the laboratory torsional fatigue test, it is proved that the bracket still has sufficient fatigue strength to meet the requirements of the braking condition under the condition of reasonably weakening the overall structural strength.
[0040] The present utility model performs grooving on several areas of the shoulder 10 and the arch waist 20, and removes the material in the non-structural area while ensuring the original design strength of the bracket to reduce the weight of the bracket. Through computer stress analysis and actual verification of the laboratory static fatigue test, grooving at the above-mentioned positions has no effect on the structural strength and life.
[0041] The above description is only the preferred embodiment of one or more embodiments of this specification, and is not intended to limit one or more embodiments of this specification. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of one or more embodiments of this specification shall be included within the protection scope of one or more embodiments of this specification.
