Abstract
The utility model discloses an automobile backshaft assembly, which comprises a hanging lug and positioning pin assembly, a bush assembly, longitudinal arm assemblies, a mounting seat assembly of a damper, a flange connecting element assembly, a cross beam and reinforced element assembly, a torsion bar and a fixed block of the torsion bar, wherein the longitudinal arm assemblies are respectively welded at both ends of the cross beam and reinforced element assembly. The utility model is characterized in that the side faces of the longitudinal arm assemblies at both sides facing to a wheel are respectively welded with two automobile stopper rope hooks; main body materials of a backshaft use QSTE460 steel of bao gang. ` The utility model has compact and reasonable structure, solves the problem of the interference of the automobile stopper braking rope and a wheel assembly, enhances the work efficiency of the automobile stopper braking rope, and has the advantages of good torsion resistant and bend resistant effect, long service life, the good passing performance and the safety of an automobile, etc.
Description
Technical field
The utility model belongs to the suspension technology of car chassis, is specifically related to a kind of automobile hind axle assembly.
Background technology
Generally do not design Parking drag-line hook on the existing automobile hind axle assembly, the easy and tire assembly interference of braking during standstill drag-line.The minority vehicle is for to avoiding this problem, on the trailing arm of automobile hind axle assembly, designed a Parking drag-line hook support, but that it is provided with the position is not ideal enough, and has only a hook, still cause the interference of braking during standstill drag-line and tire assembly easily, at all head it off.In addition, also there is the problem of torsional stiffness and bending stiffness deficiency in existing automobile hind axle.
Summary of the invention
Of the present utility model being at the prior art above shortcomings, a kind of improved automobile hind axle assembly structure is provided, make the braking during standstill drag-line be close to trailing arm, improved the work efficiency of braking during standstill drag-line, solve the problem that braking during standstill drag-line and wheel set are interfered, and improve the torsional stiffness and the bending stiffness of rear axle.
The disclosed automobile hind axle assembly of the utility model comprises hanger and locating dowel pin assembly, bush Assembly, trailing arm assembly, bumper seat assembly, flange attaching parts assembly, crossbeam and reinforcement assembly, torsion bar and torsion bar fixed block.The improvement of this hind axle assembly is that the trailing arm assembly on both sides has respectively welded two Parking drag-line hooks on the side of wheel.This helps the fixing of Parking drag-line, makes the braking during standstill drag-line be close to trailing arm, the gap between increase and wheel, and the work efficiency of raising Parking drag-line.
The material of main part of this rear axle has adopted the QSTE460 steel of Baosteel, and it has good cold forming capability and higher intensity.The rear axle torsional stiffness made from its, bending stiffness and fatigue life intensity all be improved, this helps the service life of the crossing ability and the car load of car load.
The effect of invention: compact conformation of the present utility model is reasonable, and the problem that has solved the interference of braking during standstill drag-line and wheel set has improved the work efficiency of braking during standstill drag-line.And having antitorquely, bending resistance is effective, long service life, advantage such as automobile pass ability and safety are good.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, this hind axle assembly is made of hanger and locating dowel pin assembly 1, bush Assembly 2, trailing arm assembly 3, braking during standstill drag-line hook 4, flange attaching parts assembly 5, bumper seat assembly 6, crossbeam and reinforcement assembly 7, torsion bar 8, torsion bar fixed block 9.Trailing arm assembly 3 is welded in crossbeam and reinforcement assembly 7 two ends respectively, and the trailing arm assembly 3 on both sides has respectively welded two Parking drag-line hooks 4 on the side of wheel.Torsion bar 8 and torsion bar fixed block 9 are weldingly fixed in the crossbeam groove, welding projection welding nut on bumper seat assembly 6, brazed flange on flange attaching parts assembly 5, and bumper seat assembly 6 and flange attaching parts assembly 5 be welded on the trailing arm assembly 3, at last bush Assembly 2 is compressed into bushing pipe, link to each other with locating dowel pin assembly 1 with hanger by tie bolt.
The QSTE460 steel that whole hind axle assembly has adopted Baosteel to produce.
