Abstract

The utility model discloses a rear axle twisted beam assembly, and relates to the technical field of automobile manufacturing. The rear axle twisted beam assembly comprises a twisted beam body provided with a V-type transverse beam with a downward opening. The two sides of the V-type transverse beam are connected with a left dragging arm and a right dragging arm through a left spring tray and a right spring tray respectively. A hollow twisted bar is installed in a V-type groove of the V-type transverse beam through a left twisted bar support and a right twisted bar support. A first transverse beam brake pipe support and a second transverse beam brake pipe support are respectively arranged on the V-type transverse beam. Two oppositely-arranged longitudinal arm linings are installed on the left dragging arm and the right dragging arm respectively. Compared with the prior art, the rear axle twisted beam assembly is compact in structure, the weight is reduced, the structure modality is improved, it is guaranteed that the rigidity and the strength meet the design requirement, and isolation of vibration and noise is improved.

Description

Rear axle twist beam assembly
Technical field
The utility model relates to field of automobile, especially a kind of rear axle twist beam assembly being arranged on automobile.
Background technology
The raising requiring along with economy, the environmental protection etc. of automobile, the application of the dependent rear suspension of the versions such as rear axle twist beam assembly is more and more general, a kind of important form as rear overhang rack is applied on modern general car, has the feature little, cost is low that takes up room.The version that rear axle torsion beam adopts V-type crossbeam to be connected with trailing arm by spring tray, weight, rigidity, intensity and structural modal etc. to rear axle twist beam assembly are had higher requirement.But the rear axle twist beam using at present exists weight large, Rigidity and strength is less, and to problems such as the isolation effect of vibration and noise are undesirable.
Utility model content
Problem to be solved in the utility model is to provide a kind of lightweight, Rigidity and strength reaches the rear axle twist beam assembly of designing requirement, exist weight large to solve existing rear axle twist beam, Rigidity and strength is less, and to vibration and the undesirable problem of isolation of noise.
In order to address the above problem, the technical solution adopted in the utility model is: this rear axle twist beam assembly, comprise the torsion beam body that is provided with the V-type crossbeam that Open Side Down, the both sides of described V-type crossbeam are connected with left trailing arm and right trailing arm by left spring pallet and right spring tray respectively, in the V-type groove of described V-type crossbeam, by left torsion bar anchor and right torsion bar anchor, hollow torsion bar is housed, on described V-type crossbeam, be respectively equipped with first crossbeam brake piping support and second cross beam brake piping support, two trailing arm linings that are oppositely arranged are housed on described left trailing arm and described right trailing arm.
In above-mentioned rear axle twist beam assembly technical scheme, technical scheme can also be more specifically: described left trailing arm comprises that one end is connected with the left circular tube trailing arm of bushing press-mounting pipe, the other end of described left circular tube trailing arm is connected with left shock absorber support, on described left circular tube trailing arm, be provided with trailing arm brake piping support, outside is provided with left back wheel hub bearing support, is provided with left swing arm brake piping support on left back wheel hub bearing support.
Further, described right trailing arm comprises that one end is connected with the right circular tube trailing arm of bushing press-mounting pipe, the other end of described right circular tube trailing arm is connected with right shock absorber support, on described right circular tube trailing arm, be provided with trailing arm brake piping support, outside is provided with right back wheel hub bearing support, is provided with right swing arm brake piping support on right back wheel hub bearing support.
Further, described V-type crossbeam is provided with multiple holes.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, torsion beam body of the present utility model has the V-type crossbeam that Open Side Down, both sides at V-type crossbeam are connected with left trailing arm and right trailing arm by left spring pallet and right spring tray respectively, in the V-type groove of V-type crossbeam, by left torsion bar anchor and right torsion bar anchor, hollow torsion bar is housed, two trailing arm linings that are oppositely arranged are housed on left trailing arm and right trailing arm; This compact conformation, has alleviated weight, has improved structural modal, ensures that Rigidity and strength reaches designing requirement, and vibration and noise are carried out to actv. obstruct.
2, left trailing arm and right trailing arm are respectively equipped with left circular tube trailing arm and right circular tube trailing arm, and V-type crossbeam is provided with multiple holes; Further alleviate weight, increased the obstruct to vibration and noise, reduced costs.
