Abstract

One kind reverses arm-type independent rear suspension, for all-terrain vehicle and special car.Including：Putting down to linking arm, damper, sway bar, wheel hub between wheel and vehicle body, it is frame-type reverse arm, frame-type reverse arm front bezel as the hinge shaft set being connected with vehicle body that improvements introduced, which is the linking arm, and frame-type reverse arm is assemblied on the long hinge shaft on fixed vehicle body；Connection damper, sway bar U-shaped opening both ends are connected connecting rod with the stage casing of two reverse arms respectively between the rear portion of reverse arm and vehicle body, and wheel hub is on corner on the outside of frame-type left and right side reverse arm rear end.The good effect of the utility model is：The frame-type reverse arm of use and the long hinge shaft of hinged reverse arm and vehicle body, prevent reverse arm longitudinal torsion and the horizontal swing of rear end in design field of load, reduce the lateral displacement of wheel during Suspension movement, eliminate the butterfly movement of wheel, outstanding scraping is avoided, improves the handling and stability of Ackermann steer angle.

Description

Reverse arm-type independent rear suspension

Technical field

The utility model belongs to vehicular field, and in particular to the independent wheel suspension of wheel.

Background technology：

Existing automotive wheel independence shock-proof suspension form, due to structure, wheel all can be into during the motion Row butterfly is moved, and makes the wheelspan of vehicle increase, and this lateral displacement of wheel can affect body gesture.Especially It is the full landform sport(s) car for complicated landform and scientific and technological military affairs special purpose vehicle, can turning to car using conventional suspension mechanism When handling reduction, scraping phenomenon occurs in suspension in vehicle hopping process, influences traffic safety and vehicle service life.

Utility model content

The purpose of this utility model is to provide a kind of arm-type independent rear suspension of torsion, for all-terrain vehicle and in complex landform The special car used, overcomes foregoing deficiency existing for existing independent-suspension damping system.

The rear suspension of the utility model includes：Putting down to linking arm between wheel and vehicle body（Towing arm）, damper, anti-dumping Bar, wheel hub, improvements introduced be the linking arm be frame-type reverse arm, frame-type reverse arm front bezel be tubular, as The hinge shaft set that frame-type reverse arm is connected with vehicle body, or set the hinge shaft of two coaxial lines at frame-type reverse arm front bezel both ends Set, frame-type left side reverse arm and frame-type right side reverse arm are assemblied on the long hinge shaft on fixed vehicle body by hinge shaft set；Often Vertically connection damper, sway bar U-shaped opening both ends are left with frame-type respectively between the rear portion of a frame-type reverse arm and vehicle body Side reverse arm connects connecting rod with the stage casing of reverse arm on the right side of frame-type, and two wheel hubs are attached separately to reverse arm and frame on the left of frame-type On corner on the right side of posture on the outside of reverse arm rear end.

For ease of designing, installing, reverse arm and frame-type right side reverse arm share the long hinge shaft dress of same root on the left of frame-type Fit on vehicle body, there is separation sleeve in the position on the left of the long hinge shaft upper ledge posture on the right side of reverse arm and frame-type between reverse arm.

The good effect of the utility model is：The frame-type reverse arm of use and the long hinge shaft of hinged reverse arm and vehicle body, Reverse arm longitudinal torsion and the horizontal swing of rear end in design field of load are prevented, reduces car during Suspension movement The lateral displacement of wheel, eliminates the butterfly movement of wheel, and avoiding suspension from scraping phenomenon occur makes vehicle body more stablize, and improves car Handling when turning and when turning vehicle stability, improve the security performance of vehicle.

Brief description of the drawings

Fig. 1 is the utility model overall structure stereogram.

Embodiment

Refering to Fig. 1, the utility model includes：Two putting down to linking arm 2 and 3, damper 7, preventing between wheel and vehicle body Incline bar 5, wheel hub 1, improvements introduced be the linking arm 2 and 3 be frame-type reverse arm, frame-type reverse arm front bezel be cylinder Shape, the hinge shaft set being connected as frame-type reverse arm with vehicle body, frame-type left side reverse arm 3 and frame-type right side reverse arm 2 are logical Hinge shaft set is crossed to be assemblied on the long hinge shaft 9 on fixed vehicle body；Vertically connected between the rear portion of each frame-type reverse arm and vehicle body The stage casing of damper 7, the U-shaped opening both ends of sway bar 5 respectively with reverse arm on the right side of reverse arm on the left of frame-type and frame-type connects Connective pole 4, two wheel hubs 1 are attached separately to the corner on the outside of 2 rear end of reverse arm on the right side of frame-type left side reverse arm 3 and frame-type On.There is separation sleeve 8 between reverse arm 2 on the right side of reverse arm 3 and frame-type on the left of frame-type on long hinge shaft 9.

Claims (2)

1. one kind reverses arm-type independent rear suspension, including：Putting down to linking arm, damper, sway bar, wheel between wheel and vehicle body Hub, it is characterized in that：The linking arm is frame-type reverse arm, frame-type reverse arm front bezel is tubular, is turned round as frame-type The hinge shaft set that pivoted arm is connected with vehicle body, or set the hinge shaft set of two coaxial lines, frame at frame-type reverse arm front bezel both ends Reverse arm and frame-type right side reverse arm are assemblied on the long hinge shaft on fixed vehicle body by hinge shaft set on the left of formula；Each frame-type Between the rear portion of reverse arm and vehicle body vertically connection damper, sway bar U-shaped opening both ends respectively with frame-type on the left of reverse arm Connecting rod is connected with the stage casing of reverse arm on the right side of frame-type, two wheel hubs are attached separately to reverse arm and frame-type right side on the left of frame-type On corner on the outside of reverse arm rear end.

2. a kind of arm-type independent rear suspension of torsion according to claim 1, it is characterized in that：Reverse arm and frame on the left of frame-type Reverse arm shares the long hinge shaft of same root and is assemblied on vehicle body on the right side of posture, reverse arm and frame-type on the left of long hinge shaft upper ledge posture There is separation sleeve in position between the reverse arm of right side.
