Utility model content
The technical problems to be solved in the utility model is to provide upper suspension arm before the lightweight of a kind of cross-country commander's military vehicle, before guarantee the requirement of strength of upper suspension arm own basis on, the weight of front upper suspension arm can be alleviated.
For solving the problems of the technologies described above, the technical solution of the utility model is: upper suspension arm before the lightweight of a kind of cross-country commander's military vehicle, and its innovative point is: comprise a Control arm main body;
The torsion bar spring seat coupling end that described Control arm main body distributes by being in the shape of the letter V and support end two parts form, in one end that torsion bar spring seat coupling end is connected with support end, there is a main shaft connecting bore, at the other end of torsion bar spring seat coupling end and support end, there is a torsion bar connecting bore respectively, and the axis of main shaft connecting bore is mutually vertical with the axis of torsion bar connecting bore;
Described torsion bar spring seat coupling end is strengthened being connected by connecting panel near one end of main shaft connecting bore with support end, described connecting panel one end is connected with main shaft connecting bore, the other end is positioned at the medium position of torsion bar spring seat coupling end, also has a groove at connecting panel dorsal part near main shaft connection hole;
Described torsion bar spring seat coupling end has the bolt connecting hole that four are rectangle shape distribution, at the medium position of four bolt connecting holes, also there is a mounting-positioning holes simultaneously.
Further, be connected by arc-shaped transition between described connecting panel with the madial wall of torsion bar spring seat coupling end, support end.
Further, the overall shape triangular in shape of described groove, and its three angles are arc lead angle.
Further, described Control arm entire body is made up of high-strength and high ductility iron base composite material.
The utility model has the advantage of: in the utility model, on the basis ensureing Control arm overall construction intensity, shorten the entire length of connecting panel, have groove at the back side of connecting panel simultaneously, by these two kinds of processing modes, make the overall weight of Control arm be relieved to 19.35kg by original 30.5kg, weight-loss ratio reaches 36.56%, thus reaches the object alleviating Control arm weight.
By the setting of arc-shaped transition, arc lead angle, on the basis ensureing structural strength, the length of connecting panel can be shortened to greatest extent and increases the area of groove, thus the weight alleviating Control arm that can cross as far as possible; Control arm entirety is made by high-strength and high ductility iron base composite material, the mechanical property of Control arm can also be improved more than 50%.

Detailed description of the invention
Schematic diagram is as Figure 1-Figure 5 known, and before cross-country commander's military vehicle of the present utility model lightweight, upper suspension arm comprises a Control arm main body.
The torsion bar spring seat coupling end 1 that Control arm main body distributes by being in the shape of the letter V and support end 4 two parts form, in the present embodiment, Control arm entire body is made up of high-strength and high ductility iron base composite material, by the Control arm that this material is obtained, the mechanical property of Control arm can be made to improve more than 50%.
With one end be connected of support end 4, there is a main shaft connecting bore 2 at torsion bar spring seat coupling end 1, at the other end of torsion bar spring seat coupling end 1 and support end 4, there is a torsion bar connecting bore 5 respectively, and mutually vertical between the axis of main shaft connecting bore 2 and the axis of torsion bar connecting bore 5.
