The connection structure of the axle bracket and the thrust rod in the embodiment of the invention has the following principle:
scheme one
It is assumed that one side of the wedge-shaped groove 111 is provided with a wedge surface and the other side is a vertical surface. The included angle between the wedge-shaped surface and the vertical plane is alpha1See fig. 3 and 4.
From the force analysis, the following formula is obtained:
force balance in the horizontal direction: n is a radical of1*cosα1-μ*N1*sinα1＝N2
Vertical force balance: n is a radical of1*sinα1+μ*N1*cosα1+μ*N2＝P
Wherein N is1Is the positive pressure of the wedge-shaped face in fig. 4; n is a radical of2Is a positive pressure on the vertical plane in fig. 4; p is the pre-tightening axial force of the bolt; μ is the coefficient of friction.
Can be solved to obtain:
N1＝P/(sinα1-μ2*sinα1+2μ*cosα1)
N2＝(cosα1-μ*sinα1)*P/(sinα1-μ2*sinα1+2μ*cosα1)
at this time, the maximum frictional force of the wedge attachment block 211 is:
f1＝μ*P+μ*(N1+N2)
＝μ*P*[1+(1-μ2-μ)*sinα1+(1+2μ)*cosα1]/(sinα1-μ2*sinα1+2μ*cosα1) If μ is 0.2, α1F is calculated as 10 DEG1＝0.896P，f1Is the axial direction of the pin 21.

considering the manufacturing process, the included angles between the wedge-shaped surfaces on the two sides of the wedge-shaped groove 11 and the vertical surface are equal, alpha1＝α2Then, then
N1＝N2＝P*(cosα1-μ*sinα1)/[(1-μ2)*sin(2α1)+2μ*cos(2α1)]
At this time, the maximum frictional force of the wedge attachment block 211 is:
f2＝μ*P+μ*(N1+N2)
＝μ*P+2μ*P*(cosα1-μ*sinα1)/[(1-μ2)sin(2α1)+2μ*cos(2α1)]
if μ is 0.2, α1F is calculated as 10 DEG2＝0.74P，f2Is the axial direction of the pin 21. Thus, f can be obtained2＝1.85f0。
If μ is 0.2, α1F is calculated as 5 DEG20.898P. Thus, f can be obtained2＝2.24f0。
From the above analysis, it can be known that, according to the second scheme, the maximum friction force of the wedge-shaped connecting block 211 at the end of the pin shaft 21 can be increased, and the reliability of the connection between the axle bracket 1 and the thrust rod 2 is improved.
In addition, when the sum of the included angles between the wedge surfaces at the two sides of the wedge-shaped groove 111 and the vertical plane is equal to 10 degrees, namely alpha1+α2By 10 °, it is known that scheme one and scheme two are equivalent.

at this time, the maximum friction force of the wedge attachment block 211 may be:
f1＝μ*P+μ*(N1+N2)
＝μ*P*[1+(1-μ2-μ)*sinα1+(1+2μ)*cosα1]/(sinα1-μ2*sinα1+2μ*cosα1) If μ is 0.2, α1F is calculated as 10 DEG1＝0.896P，f1In the direction in which the wedge-shaped connection block 211 slides along the wedge-shaped groove 11.
