Embodiment Construction
[0010] This embodiment is used to explain the claims, and the scope of protection of the present invention is not limited to the description of the following structures. What those skilled in the art do based on the hints and instructions of the technical solutions proposed in this claim are different from those of this embodiment. Structures all belong to the protection scope of the present utility model.
[0011] like figure 1 As shown, the wheel 1 is hinged to connect the upper triangle arm assembly 2 and the lower triangle arm assembly 3; The arm assembly 3 is connected to the spring shock absorber assembly 4, and the connection point between the lower triangle arm assembly and the spring shock absorber assembly is not at the midpoint of the lower triangle arm assembly, that is, the spring shock absorber assembly and the lower triangle arm The connection point of the assembly is not at the midpoint in the length direction of the lower triangle arm assembly. The other two...

The invention discloses a double arm independent suspension without a stabilizer bar, which comprises an upper triangular arm assembly of which one end is hinged with a wheel, and a lower triangular arm assembly of which one end which is hinged with the wheel, wherein the lower triangular arm assembly is connected with a spring shock absorber assembly, the vertex angle of the hinged joint between the upper triangular arm assembly and the wheel is between 35 and 60 degrees, and the vertex angle of the hinged joint between the lower triangular arm assembly and the wheel is also between 35 and 60 degrees. Two connection points of the lower triangular arm assembly hinged with a frame are not in the same level plane, thereby the double arm independent suspension without the stabilizer bar is formed. The double arm independent suspension cancels the stabilizer bar which prevents the suspension spring from being deformed and reduces the transverse inclination and the transverse angular vibration of a vehicle, but does not change the driving performance of the whole vehicle, thereby achieving the aim of reducing component number of the suspension assemblies without changing other performances of the vehicle, simplifying the structure of the double arm independent suspension, and reducing cost.
Description
technical field [0001] The invention belongs to vehicle parts, in particular to an independent suspension with a double wishbone structure. Background technique [0002] After the off-road vehicle adopts the independent suspension, especially the double-wishbone independent suspension, there is a phenomenon of insufficient suspension stiffness, which causes a large roll angle when the vehicle turns. In order to avoid this phenomenon and improve the roll angle stiffness of the suspension, a lateral stabilizer (rod) is often added to the suspension to ensure good driving stability of the car. After adopting the anti-roll bar, when the direction of movement of the coaxial wheels (jump up and down) is the same, the lateral stabilizer does not work; when the direction of movement of the coaxial wheels (jump up and down) is different, the vehicle body will When the wheel is tilted upwards, the side of the wheel jumps up and moves toward the body, and the end of the same side of t...
