Abstract
The invention relates to an off-road commanding military vehicle lightweight upper front control arm. The control arm comprises a control arm body. The control arm body is composed of a torsion rod spring base connecting end and a supporting end, wherein the torsion rod spring base connecting end and the supporting end are distributed in the shape of V. The end, connected with the supporting end, of the torsion rod spring base connecting end is provided with a main shaft connecting hole. The other end of the torsion rod spring base connecting end and the other end of the supporting end are each provided with a torsion rod connecting hole, and the axis of the main shaft connecting hole is perpendicular to the axes of the torsion rod connecting holes. The end, close to the main shaft connecting hole, of the torsion rod spring base connecting end and the end, close to the main shaft connecting hole, of the supporting end are in enhanced connection through a connecting plate. One end of the connecting plate is connected with the main shaft connecting hole, and the other end of the connecting plate is located in the middle of the torsion rod spring base connecting end. The back side, close to the main shaft connecting hole, of the connecting plate is further provided with a groove. The control arm has the beneficial effect that by reducing the overall length of the connecting plate and forming the groove on the back side of the connecting plate, the purpose of reducing the weight of the control arm is achieved.

At present, stub is connected in cross-country commander's military vehicle, the upper front control arm of automobile of torsion bar and torsion bar spring seat, its structure is made up of the torsion bar spring seat coupling end of V-shaped distribution and support end two parts, with one end be connected of support end, there is a main shaft connecting bore at torsion bar spring seat coupling end, at the other end of torsion bar spring seat coupling end and support end, there is a torsion bar connecting bore respectively, in order to ensure structural strength, need to strengthen link of boards torsion bar spring mount pad coupling end and support end by one, and traditional its length of reinforcement gusset is long, its one end is connected with main shaft connecting bore, the other end is torsion bar connecting bore relatively, and its thickness is thicker, be about 15mm, by such setting, although the intensity of structure can be ensured, but the heavier-weight of front upper suspension arm entirety can be caused, total mass reaches 30.5kg.
Summary of the invention
The technical problem to be solved in the present invention 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, technical scheme of the present invention 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 invention has the advantages that: in the present invention, 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%.
