Abstract
The utility model discloses the connection structures of a kind of rear brake caliper and rear torsion beam, including rear brake caliper, rear torsion beam, connecting plate and rear caliper bracket, brake caliper is connect with rear caliper bracket after described, and rear caliper bracket is connect with connecting plate, and connecting plate is connect with rear torsion beam；Layout angle after described between brake caliper and rear torsion beam is 10 °~35 °, the connecting plate with a thickness of 12mm~17mm.The layout angle between rear torsion beam that the utility model passes through brake caliper after optimization, and the thickness of connecting plate, so that the lateral single order torsion mode after rear caliper bracket is connect with connecting plate is greater than 600HZ, therefore effectively evade braking MOAN noise, improves customer experience.
Description
Technical field
The utility model belongs to brake system of car, and in particular to the connection knot of brake caliper and rear torsion beam after a kind of
Structure.
Background technique
As shown in Figure 1, rear suspension uses the vehicle of rear 1 suspension frame structure of torsion beam, connecting plate 3 is by rear brake caliper 2 with after
Torsion beam 1 links together, and group is integral.Automobile, because friction block vibration is transferred to rear torsion beam 1, causes when low speed is braked
Torsion beam 1 is vibrated together afterwards, generates low frequency noise, i.e., (mode of oscillation of braking MOAN noise is distributed in braking MOAN noise
400-600HZ).
Utility model content
The purpose of the utility model is to provide the connection structures of a kind of rear brake caliper and rear torsion beam, to evade braking
MOAN noise improves customer experience.
The connection structure of brake caliper and rear torsion beam after described in the utility model, including rear brake caliper, rear torsion
Beam, connecting plate and rear caliper bracket, the rear brake caliper are connect with rear caliper bracket, and rear caliper bracket is connect with connecting plate,
Connecting plate is connect with rear torsion beam；Layout angle after described between brake caliper and rear torsion beam is 10 °~35 °, the company
Fishplate bar with a thickness of 12mm~17mm.
Further, the layout angle between the rear brake caliper and rear torsion beam is 10 °.
Further, the connecting plate with a thickness of 15mm.
The utility model has the advantage that the layout angle between rear torsion beam by brake caliper after optimization,
And the thickness of connecting plate, so that the lateral single order torsion mode after rear caliper bracket is connect with connecting plate is greater than 600HZ,
Therefore effectively evaded braking MOAN noise, improve customer experience.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the prior art；
Fig. 2 is one of the connection schematic diagram of connecting plate and rear caliper bracket in the utility model；
Fig. 3 is two of the connection schematic diagram of connecting plate and rear caliper bracket in the utility model；
In figure: 1, rear torsion beam, 2, rear brake caliper, 3, connecting plate, 4, rear caliper bracket, 5, First Line, 6, second
Line, the 7, first mounting hole, the 8, second mounting hole.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, the connection structure of rear brake caliper and rear torsion beam, including rear brake caliper 2, rear torsion beam 1, company
Fishplate bar 3 and rear caliper bracket 4, the rear brake caliper 2 are connect with rear caliper bracket 4, and rear caliper bracket 4 is connect with connecting plate 3,
Connecting plate 3 is connect with rear torsion beam 1.
As shown in Figures 2 and 3, in the present embodiment, pass through the cloth after optimization design between brake caliper 2 and rear torsion beam 1
It is rigid to improve the assembly after rear caliper bracket 4 is connect with connecting plate 3 for angle α between angle setting degree, i.e. First Line 5 and the second line 6
Property.Wherein, First Line 5 is the company for two the first mounting holes 7 for connecting with rear caliper bracket 4 being arranged on connecting plate 3
Line；Second line 6 is two lines being used for the second mounting hole 8 of rear axis connection being arranged on connecting plate 3.When First Line 5
Angle α between the second line 6 is calculated within the scope of 10 °~35 ° by CAE, and rear caliper bracket 4 connect total with connecting plate 3
600HZ is all larger than in vehicular transverse direction single order torsion mode at component.For example, when the angle between First Line 5 and the second line 6
It when α is 35 °, is calculated by CAE, the assembly component that rear caliper bracket 4 is connect with connecting plate 3 is reversed in vehicular transverse direction single order
Mode is 611HZ.In addition, also can reach the purpose for increasing rigidity, but consider light weight by the thickness for increasing connecting plate 3
Change and require, the thickness of connecting plate 3 is typically designed in 12mm-17mm.
As shown in Figures 2 and 3, the layout angle between rear brake caliper 2 and rear torsion beam 1 is designed as 10 °, i.e., when
When angle between one line 5 and the second line 6 is 10 °, and the thickness of connecting plate 3 is designed as 15mm, and CAE analysis blocks after calculating
The assembly component of pincers bracket 4 and connecting plate 3 is 717HZ in direction of traffic single order torsion mode, passes through vehicle and brakes MOAN test
Test does not occur braking MOAN noise, has effectively evaded braking MOAN noise.
