The full air rear suspension of the automobile of said structure structure, because Panhard rod 33 and vertical propelling rod 31, longitudinal rod 32 are with respect to the car load fore-and-aft direction, lay respectively at the both sides, front and back of back axle 30, its longitudinal size is bigger, take the big longitudinal space of car load, on single back axle, more easily arrange, but arrange that on two back axle automobiles difficulty is very big, almost can't realize.
Summary of the invention
The technical problems to be solved in the utility model is the both sides, front and back that longitudinal rod and Panhard rod lay respectively at back axle, it is big to take the car load longitudinal space, difficulty is used for two back axle automobiles, the utility model provides that a kind of to take the car load longitudinal space little, can be arranged in the full air back suspension device of automobile of dual-rear axle commercial car.
The full air back suspension device of the utility model automobile, comprise chassis side rail, crossbeam, be positioned at chassis side rail below and be fixed on equalizer on the back axle, be distributed in the air bag at equalizer two ends, two ends are separately fixed at the bumper on chassis side rail and the back axle, and two ends are hinged on the V-shaped vertical propelling rod on chassis side rail and the back axle respectively, also comprise the propelling rod that takes the shape of the letter U, the place, two ends of the transverse bar part of U-shaped propelling rod is hinged on the equalizer respectively, two longitudinal rod partial fixings of U-shaped propelling rod are on chassis side rail, and the vertical propelling rod of U-shaped propelling rod and V-arrangement is positioned at the same side of back axle.
Introduce function of the present utility model below.
The longitudinal rod part of U-shaped propelling rod, the vertical propelling rod of V-arrangement, vehicle frame and back axle constitute parallel four-bar linkage, guarantee the path of motion of vehicle bridge.
When the relative road-bank elevation of vehicle body, both sides suspension distortion does not wait, the longitudinal rod part of U-shaped propelling rod is to different directions deflection, the angle difference that turns over, produce twist moment, the different distortion that stops the both sides air bag plays the effect that hinders body inclination, reduces the lateral inclination and the lateral angle vibration of vehicle body.
When vehicle body was done the above-below direction motion, the angle that the longitudinal rod of U-shaped propelling rod partly turns over was identical, does not produce twist moment, guarantees the movement in vertical direction track of vehicle bridge.
In sum, the beneficial effects of the utility model are as follows:
The full air back suspension device of the utility model, the vertical propelling rod of U-shaped propelling rod and V-arrangement is in the same side of back axle, the car load longitudinal space that takies is little, not only can be arranged on single rear axle commercial car, can also be arranged on the dual-rear axle commercial car, solve the difficult problem that two driving rear axle are difficult to adorn full air suspension.
The full air back suspension device of the utility model, simple in structure, cost is low, has reduced integral vehicle cost, has improved the car load market competitiveness.
Below, the utility model is described in further detail by the specific embodiment.
Description of drawings
Fig. 1 is the full air back suspension device of an automobile structural representation.
Fig. 2 is the full air back suspension device of an automobile structural representation front view.
Fig. 3 is a background technology scenario-frame scheme drawing.
The specific embodiment:
Referring to Fig. 1, Fig. 2, present embodiment is the full air back suspension device that is installed on the dual-rear axle commercial car, comprise chassis side rail 10, cross member of frame 12, be fixed on the back axle 19 and be positioned at two equalizers 18 of chassis side rail 10 belows, be installed in the air bag 2 at equalizer 18 two ends by air bag 2 supports 6, two ends are separately fixed at the bumper 3 on chassis side rail 10 and the back axle 19, top tip part is hinged on back axle 5 middle parts, two ends are hinged on the V-shaped vertical propelling rod 13 on the chassis side rail 10 in addition, and the propelling rod 16 that takes the shape of the letter U.
Also referring to Fig. 1, Fig. 2, rubber bush 7 is installed at transverse bar part 15 two ends of U-shaped propelling rod 16, and the propelling rod permanent seat 17 of band rubber shaft bearing is installed on the equalizer 18, and U-shaped propelling rod 16 is hinged on the propelling rod permanent seat 17; Two longitudinal rod parts 14 of U-shaped propelling rod 16 are separately fixed on the chassis side rail 10, and U-shaped propelling rod 16 is indulged the same side that propelling rod 13 is positioned at back axle 5 with V-arrangement.
Owing to be the dual-rear axle commercial car, therefore, full air back suspension device is installed respectively on two back axles 5, the vertical propelling rod 13 of two V-arrangements of cloth postpone is two V-arrangements, and two U-shaped propelling rods 16 are dual U-shaped.
Introduce the function of present embodiment below.
The longitudinal rod part 14 of U-shaped propelling rod 16, the vertical propelling rod 13 of V-arrangement, chassis side rail 10 and back axle 5 constitute parallel four-bar linkage, guarantee the path of motion of vehicle bridge.
When the relative road-bank elevation of vehicle body, both sides suspension distortion does not wait, the longitudinal rod part 14 of U-shaped propelling rod 16 is to different directions deflection, the angle difference that turns over, produce twist moment, the different distortion that stops both sides air bag 2 plays the effect that hinders body inclination, reduces the lateral inclination and the lateral angle vibration of vehicle body.
When vehicle body was done the above-below direction motion, the angle that the longitudinal rod part 14 of U-shaped propelling rod 16 turns over was identical, does not produce twist moment, guarantees the movement in vertical direction track of vehicle bridge.
In sum, the beneficial effect of present embodiment is as follows:
U-shaped propelling rod 16 is indulged propelling rod 13 in the same side of back axle 5 with V-arrangement, and the car load longitudinal space that takies is little, therefore can be arranged on the dual-rear axle commercial car, has solved the difficult problem that two driving rear axle commercial vehicle/comm..vehicles are difficult to adorn full air rear suspension.
The full air back suspension device of present embodiment, simple in structure, cost is low, has reduced integral vehicle cost, has improved the car load market competitiveness.
Certainly, the full air back suspension device of the invention automobile can also be installed on single rear axle commercial car, has same function and effect.
