The automobile steering wheel bears various complex forces and moments in the driving process of the automobile, and has great influence on the driving maneuverability, stability and comfort of the automobile.
In the automobile design, strict requirements are imposed on the three-dimensional rigidity of the auxiliary frame bushing. Due to the fact that the structural design of the auxiliary frame bushing is complex, the development difficulty is high, the modification period is long, and the structural redesign can be caused by independently changing the rigidity of any one direction. During vehicle tuning, it is sometimes necessary to increase the axial stiffness of the subframe bushing, which can lead to bushing redesign, which can delay the entire project cycle.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1 and 2, a mechanism for improving the axial rigidity of a subframe bushing includes a subframe bushing 3, and is characterized in that: the axial action rubber 2 at the upper part of the bushing and the axial action rubber 4 at the lower part of the bushing are also included;
the upper axial acting rubber 2 and the lower axial acting rubber 4 are both composed of a plurality of rubber protruding blocks, and are vulcanized on the upper portion or the lower portion of the auxiliary frame bushing 3, and the structure or the number of the rubber protruding blocks is adjusted according to the requirement of axial rigidity.
The upper axial acting rubber 2 consists of 3-8 rubber lugs; the lower axial acting rubber 4 consists of 3-8 rubber lugs.
The upper axial acting rubber 2 and the lower axial acting rubber 4 respectively contact with the upper limiting sheet 1 and the lower limiting sheet 5 after the actual vehicle is assembled and have pre-compression amount.
The sub frame bushing 3 is a general sub frame bushing.
To study the effect of increasing the axial stiffness of the subframe bushing by the rubber bump structure and number, take 3 upper axially acting rubbers 2, 6 upper axially acting rubbers 2, and 3 rubber bumps, but the volume of the rubber bumps is reduced by half.
Fig. 3 is a view showing that the axial rigidity is increased by doubling the number of rubber lugs, and fig. 4 is a view showing that the increase in the axial rigidity is decreased by reducing the volume of the rubber lugs by half.
Experimental results show that when the number of the upper axial acting rubber 2 is 3, the axial rigidity of the auxiliary frame bushing is 75N/mm, when the number of the upper axial acting rubber 2 is 6, the axial rigidity of the auxiliary frame bushing is 150N/mm, and the axial rigidity of the auxiliary frame bushing is 37.5N/mm when the volume of the rubber bump is reduced by half. It can be seen that the subframe bushing axial stiffness can be increased by adjusting the rubber lug structure and number individually.
