Description

Torsion beam type axletree

Technical field

The utility model relates to a kind of torsion beam type axletree (torsionbeamaxle), and more specifically, relates to a kind of torsion beam type axletree enhancing attachment force between torsion beam and trailing arm.

Background technology

Torsion beam type axletree is a kind of for by suspension system in wheel supporting to chassis, and comprises torsion beam and a pair trailing arm, and left back (front) wheel and right back (front) are taken turns and be coupled to chassis by trailing arm, and torsion beam is connected between trailing arm.

This torsion beam type axletree can realize main technical goal.One of target be by provide when revolver and right take turns between distortion time also can the torsion beam of distortion and the advantage had as independent suspension system.Meanwhile, the advantage of fixing luggage cabin and competitive price should be realized.And, weight saving should be realized by the optimal design of torsion beam.

In the material of torsion beam type axletree, usual cast iron is used for trailing arm to strengthen revolver or right bearing force of taking turns.For torsion beam, use steel with flexibly distortion, absorb simultaneously easily revolver and right take turns between distortion.

Consideration must guarantee to have predetermined anchoring strength between trailing arm and torsion beam, to meet the condition that torsion beam type axletree should meet above requirement, because trailing arm and torsion beam are made up of above-mentioned different material, so the associated methods of different materials becomes a major issue.

Although usually there is the situation of bonded block (such as bolt, nut etc.) as associated methods, due to this in conjunction with the anchoring strength of weakness, this combination is easily ruptured.

On the other hand, introduce friction welding to be welded by the rotating contact between trailing arm and torsion beam thus to connect trailing arm and torsion beam, as in US Patent the 6th, described in 059, No. 314 " complex controll arm axle and manufacture method (METHODOFMANUFACTURINGACOMPOSITECONTROLARMSHAFTFORMOTORVE HICLEANDCOMPOSITECONTROLARMSHAFT) thereof for power actuated vehicle " (record dates: on May 9th, 2000).But this exists needs the problem of Large expensive equipment and this problem weakens the competitive power of manufacturing cost aspect.

Utility model content

Therefore, the purpose of this utility model is to provide the torsion beam type axletree between a kind of torsion beam being made from a variety of materials and trailing arm with the binding force of enhancing.

In order to realize above target, the utility model provides a kind of torsion beam type axletree, and comprising: a pair trailing arm, trailing arm is casting; And torsion beam, torsion beam is integrally formed with a pair trailing arm with two of insert molding torsion beam end sections by being inserted in a pair trailing arm by two of torsion beam end sections when casting a pair trailing arm.

According to one side of the present utility model, torsion beam is formed with slot in two end sections, to strengthen trailing arm and to be inserted into the anchoring strength between two end sections in this trailing arm when casting trailing arm.

According to one side of the present utility model, described torsion beam has baffle plate, and this baffle plate is inserted in two end sections of torsion beam, flow in two end sections be inserted into when casting trailing arm in this trailing arm to stop the material of trailing arm.

According to one side of the present utility model, trailing arm is made up of aluminum alloy, and torsion beam is formed from steel.

According to above-mentioned torsion beam type axletree of the present utility model, in the casting process treating integrally formed trailing arm, insert torsion beam.Therefore, the binding force between trailing arm and torsion beam can be strengthened.

Fig. 2 is the partial enlarged drawing of the forming process of torsion beam type axletree for describing Fig. 1; And

Fig. 3 is the block diagram of the torsion beam of the parts of torsion beam type axletree as Fig. 1.

Detailed description of the invention

As shown in fig. 1, comprise torsion beam 110 and a pair trailing arm 120 according to the torsion beam type axletree 100 of illustrative embodiments of the present utility model, this combines to the two ends of trailing arm with torsion beam 110.

Torsion beam 110 is continuous-tubes, and the central part office of this continuous-tube has " U " shape or " V " shape cross-sectional plane (with reference to Fig. 3), and two of this continuous-tube end portion offices have circular cross section.

Due to this shape, so the core of torsion beam 110 can easily elastic distortion.

This torsion beam 110 is made up of the method for hydraulic forming usually, wherein, has the hollow tubular pressurized of circular cross section and is out of shape.Usually, torsion beam 110 is formed from steel.

Trailing arm 120 has the chassis bound fraction 121 that is combined with chassis and the incorporated in vehicle wheels part 122 with incorporated in vehicle wheels.Trailing arm 120 is integrally coupled to torsion beam 110 by the method for the insert molding described after a while.

Compared with torsion beam 110, trailing arm 120 is preferably made up to make trailing arm can not be caused distortion by the external force by chassis or wheel easily of the material of high strength.For this reason, the aluminum alloy of high strength can be used as the material of trailing arm 120.

Because torsion beam type axletree 100 has this structure, so absorb the different force from two wheels by the torsional deflection of torsion beam 110.And wheel and chassis stably can be supported by trailing arm 120.

As shown in Figure 2, torsion beam 110 is by being inserted into insert molding in trailing arm 120 respectively by two end sections 111, and a pair trailing arm 120 is castings.

That is, when casting trailing arm 120, torsion beam 110 is inserted in casting mould to make two of torsion beam end sections 111 project in casting mould.Then, the aluminum alloy be in molten condition is poured in casting mould integrally to be formed with torsion beam 110 in the process of setting of aluminum alloy.

In this case, multiple slot 112 is formed to strengthen the binding force between end sections 111 and trailing arm 120 at two end sections 111 places of torsion beam 110.

In addition, as shown in Figure 3, baffle plate 113 is inserted into weld in two end sections 111 of torsion beam 110 wherein, can not flow in the end sections 111 of torsion beam 110 to make the aluminum alloy be in the casting process of trailing arm 120 in molten condition.

Be not limited to the torsion beam of above-mentioned circular cross section according to torsion beam type axletree of the present utility model, but this torsion beam type axletree can have the torsion beam of polygon, ellipse or other cross-sectional planes if necessary.

Although disclosed illustrative embodiments of the present utility model, when not deviating from scope and spirit of the present utility model, various amendment, interpolation and replacement can be carried out.Therefore, above embodiment should be regarded as describing the utility model example, but not for limiting the utility model.
