Abstract
The utility model relates to a torsion beam rear suspension, which is characterized in that the torsion beam suspension comprises a shock absorber, the two ends of the shock absorber are respectively connected with two torsion beams, and each torsion beam is connected with a car body through a helical spring which is installed at one end of the torsion beam; a hub unit mounting bracket is welded at one end of each torsion beam; and the middle sections of the torsion beams are bend and raised upwards. The torsion beams have a function of leaving sufficient arrangement spaces for a rear drive shaft and a rear main speed reducer during the arrangement of a four-wheel-drive car, so as to ensure that sufficient clearances are kept between the rear drive shaft and the torsion beam and between the rear main speed reducer and the torsion beam when the rear suspension moves between an upper limit and a lower limit; and at the same time, the welded torsion beam is entirely put at a machining center or on special equipment to re-machine a mounting surface between the hub unit mounting bracket on the torsion beam and a hub unit, so as to ensure rear wheel positioning parameters after car assembling.
Description
Technical field
The utility model relates to a kind of compact 4 wheel driven SUV, is specifically related to the twist beam-type rear suspension that a kind of SUV car adopts, and belongs to International Classification of Patents B60/B62 technical field.
Background technology
Great majority adopt the small-sized SUV car of self-supporting body, generally all are f-w-ds, and rear suspension adopts the semi-independent suspension of torsion girder-like.When needs carried out the 4 wheel driven layout on this vehicle basis, owing to increased parts such as rear propeller shaft, rear primary gearbox, original structure can not satisfy new demand.Therefore, when arranging rear suspension,, just need carry out design modification, to satisfy the needs of 4 wheel driven vehicle to former torsion beam etc. in order to dodge out the parts that these increase newly.
Summary of the invention
The purpose of this utility model is to provide a kind of and can satisfies the twist beam-type rear suspension that the 4 wheel driven vehicle is arranged needs better.
The technical solution of the utility model is as follows.
A kind of twist beam-type rear suspension comprises parts such as torsion beam, coil spring, bumper, and the bumper two ends connect two torsion beam respectively, coil spring and body contact that each torsion beam is equipped with by the one end.Torsion beam one end also is welded with the hub mounting bracket.The stage casing of torsion beam upwards is bend relief, reserves enough arrangement space for rear propeller shaft and rear primary gearbox, guarantees rear suspension in the high-low limit motion process, and rear propeller shaft, rear primary gearbox and torsion beam have enough gaps.
Twist beam-type rear suspension of the present utility model is for being applicable to the rear suspension of compact 4 wheel driven SUV.After raising up, turn round beam, reached and on this front wheel drive car, carried out the effect that 4 wheel driven is arranged from middle position.Simultaneously, all weldments such as hub mounting bracket are welded to turns round Liang Shanghou, whole again the hub mounting bracket is carried out time processing, guarantees the trailing wheel positional parameter after the entrucking.
Description of drawings
Fig. 1 is the structural representation of the utility model twist beam-type rear suspension;
Fig. 2 is the scheme drawing of torsion beam.
Among the figure: 1, bumper, 2, torsion beam, 3, coil spring, 4, the hub mounting bracket.
The specific embodiment
Referring to Fig. 1, twist beam-type rear suspension comprises bumper 1, and bumper 1 two ends connect two torsion beam 2 respectively, and each torsion beam 2 connects with vehicle body by one end bonded assembly coil spring 3; One end of torsion beam 2 is welded with hub mounting bracket 4.Simultaneously, bumper 1 is connected to this rear suspension on the vehicle body by mounting bracket on the torsion beam 2 and the bumper mounting bracket on the vehicle body, coil spring 3 is housed as elastic element between vehicle body and the torsion beam 2.Rear propeller shaft and rear primary gearbox be arranged in torsion beam 2 below.Like this, can guarantee that rear propeller shaft, rear primary gearbox have enough gaps in the motion process of rear suspension and between the torsion beam 2.
Referring to Fig. 2, the interlude of torsion beam 2 upwards is bend relief.Torsion beam 2 links by corresponding mounting bracket on left and right each one group of bolt 3 and the vehicle body.Simultaneously, be connected with bumper 1 between the corresponding bumper mounting hole on damper bracket on the torsion beam 2 and the vehicle body.
In order better to guarantee the trailing wheel positional parameter, hub mounting bracket 4 on being welded to torsion beam 2 after, work in-process in the heart or specialized equipment reprocessing once, in order to guarantee the trailing wheel positional parameter after the entrucking.
