Abstract
The utility model discloses an suspender for vehicles, which overcomes the disadvantage of big differ of offset frequency under the state of idle load and full load in prior vehicles, improves the ride performance of the vehicles, realizes a changeable rigidity in the suspension system, and keeps the consistency of the bicycle frame height under all situations, so as to make the vehicle have suitable vibration reduction performance and good controlling stability. People feel stable and safe when driving the vehicle, a new suspender is provided for the suspension system of the vehicles, and the suspender is suitable for the axle of the multiple transfixions heavy-duty car. The structure is an air suspender, which is characterized in that the suspender consists of a bracket, the bracket is provided with an air spring device, which is connected with the axle, and the axle is connected to the thrusting rod guiding device.
Description
Technical field
The utility model relates to a kind of vehicle bridge suspension gear of automobile, relates in particular to the vehicle bridge suspension gear of a kind of multiple-shaft whole-wheel driving or part wheel drive vehicle.
Background technology
In the manufacturing process of automobile, should guarantee that automobile has good riding comfort, suitable cushioning performance and road-holding property; Guarantee that automobile can keep vehicle body stable in braking with when quickening, reduce the vehicle body trim possibility, can transmit shear force and moment between vehicle body and the wheel reliably, the parts light weight also has enough intensity and life-span.For the suspension system of multi-wheeler, what adopt usually is steel spring balance suspension or half balance suspension, but steel spring offset frequency under unloaded and fully loaded state differs bigger, and can not guarantee the conformability of chassis frame height at unloaded and fully laden.
Summary of the invention
The purpose of this utility model is exactly to differ bigger shortcoming in order to overcome existing car load offset frequency under unloaded and fully loaded state, a kind of suspension system that suitable cushioning performance and good road-holding property are arranged in vehicle traveling process is provided, guarantees vehicle frame highly conformability under unloaded and fully laden.
The utility model has adopted following technical scheme for achieving the above object: a kind of air suspension system is characterized in that: it has support, and air spring device is housed on the support, and this device connects with vehicle bridge, and vehicle bridge also connects with the propelling rod guide piece.
Described air spring device comprises air bag, and it and equalizer connect firmly, and connects with levelling valve by pipeline.
Air bag top connects with vehicle frame by support, and the air bag bottom is by the bolted connection equalizer, and equalizer connects with vehicle bridge by bolt with pressing plate simultaneously; Pipeline connects with an end of air bag and levelling valve, and the other end of levelling valve is connected on the vehicle bridge.
Support is fixed on the vehicle frame, is made by a bent plate, and front central has a circular hole, can with the Bolt Connection of air-spring bellows upper flange center.
Described propelling rod guide piece has last longitudinal rod and following longitudinal rod for it, and their ends are connected on the vehicle bridge, and the other end is connected on the crossbeam of vehicle frame, and lateral rod is connected on the vehicle bridge.
Because the utility model has adopted air bellow, support, equalizer have been set up, in the speciality car motion process, because support and vehicle frame are fixed together, equalizer is linked together by bolt and pressing plate, increased simultaneously height-control valve again, thereby the variation that has guaranteed the air bag height limits within the specific limits, ride of vehicle have so just been changed general, realized the variable steel-degree of suspension system, keep the conformability of chassis frame height under various conditions altogether, make automobile that suitable cushioning performance be arranged, good road-holding property.The car load steady safety of travelling for the suspension system of automobile provides a kind of novel draft hitch, is particluarly suitable for using on the vehicle bridge of multi-joint perforation heavy motor vehicle.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the front view of air suspension apparatus.
Fig. 2 is the birds-eye view of air suspension apparatus.
Fig. 3 is the front view of air suspension apparatus at four, five bridge places.
Fig. 4 is the structural representation of levelling valve.
The specific embodiment
Among Fig. 1, support 1 is fixed on the vehicle frame 8 of speciality car, and it is to be made by a bent plate, and the front central of support 1 is provided with a circular hole, is used to connect the bolt of air-spring bellows 2 upper flange centers, and air bag 2 is linked together by support 1 and vehicle frame 8.Also there is a bolt at the lower central place of air bag 2, and this bolt is used to connect the flange at place, equalizer 3 two ends, and equalizer 3 is linked together by four overbolts 6 and vehicle bridge 9 with pressing plate 5 simultaneously.Among Fig. 2, last longitudinal rod 11 and following longitudinal rod 12 1 ends are coupled on the vehicle bridge 9, the other end is coupled on the crossbeam of vehicle frame 8, lateral rod 13 is connected on the vehicle bridge 9, the effect that so just has lateral rod, also prevented the left and right sides play of air bag 2, air bag 2 just can transmit shear force and the moment between the wheel 10 among vehicle frame 8 and Fig. 3.Pipeline 4 is used to regulate air bag 2 height, the height of air bag 2 mainly is by being installed in the motor-driven control of levelling valve 7 (shown in Figure 4) on the pipeline 4, one end of levelling valve 7 is connected on the vehicle bridge 9, when vehicle bridge 9 is beated when reaching a certain height, the levelling valve 7 that is connected in vehicle bridge 9 one ends will start the switch of the levelling valve other end, air bag 2 is charged and discharged gas, can regulate the height of air bag 2 thus.That is to say that no matter how violent beating of bridge have, the height of air bag 2 can keep within the specific limits in the adjusting by levelling valve.Like this, just realized the change rigidity of suspension system, made suspension system under unloaded and fully laden, lower offset frequency be arranged all, guaranteed ride of vehicle, taken pleasant.
