Description
Technical Field
The invention relates to an air suspension for a heavy-duty car, in particular to a single swing arm air suspension system with an air bag lifting device for a non-driving supporting bridge.
Background
For the multi-axle heavy-duty car, when the car runs empty, the effect exerted by the non-driving support bridge is smaller, at the moment, the driving support bridge of the car is enough to bear the weight of the car body, and the non-driving support bridge is not needed to share the stress, but the multi-axle heavy-duty car is limited by the existing structure, when the car runs empty, the tires on the non-driving support bridge still contact with the ground, so that the tires are worn, and resistance exists when the tires contact with the ground, so that the fuel consumption of the car in the empty state is correspondingly increased.
Disclosure of Invention
Aiming at the problems in the background art, the invention provides a single swing arm air suspension system with an air bag lifting device for a non-driving support bridge, which comprises two sets of guide arm assemblies, a through beam and two air springs; the guide arm assembly comprises a guide arm bracket, a guide arm and a connecting piece; one end of the guide arm is rotationally connected with the guide arm bracket, the other end of the guide arm is connected with the lower side surface of the end part of the through beam, and the guide arms on the two sets of guide arm assemblies are respectively corresponding to the two ends of the through beam; the lower ends of the air springs are connected with the upper side surfaces of the ends of the through beams, the two air springs are respectively corresponding to the two ends of the through beams, the upper ends of the air springs are connected with the frame through supporting seats, and the two air springs are respectively corresponding to the two supporting seats; the support bridge is transversely arranged above the two sets of guide arm assemblies, and the middle parts of the corresponding guide arms are connected with the support bridge by connecting pieces on the two sets of guide arm assemblies;
the innovation is that: the single swing arm air suspension system is provided with an air bag lifting device; the air bag lifting device consists of a lifting air bag, a lifting arm, a connecting frame and a supporting arm; the lifting air bag is arranged above the through beam and between the two air springs, a space is reserved between the lifting air bag and the through beam, and the force application direction of the lifting air bag is parallel to the force application direction of the air springs; the lifting arm is of an inverted U-shaped structure, the lower side face of the lifting arm concave part is connected with the upper end face of the lifting air bag, and the two ends of the lifting arm opening part are respectively positioned at the two axial sides of the through beam; the upper side surface of the middle part of the connecting frame is connected with the lower side surface of the through beam, the position of the connecting frame is positioned right below the lifting air bag, and the two ends of the connecting frame are respectively connected with the two ends of the opening part of the lifting arm; the support arm is U-shaped structure, and the support arm depressed part sets up between promoting the gasbag and link up the roof beam, and the up side of support arm depressed part is connected with the lower terminal surface that promotes the gasbag, leaves the interval between the downside of support arm depressed part and the roof beam that link up, and the both ends of support arm opening are connected with two supporting seats respectively.
The principle of the invention is as follows: when the heavy-duty car is in a loading state, the air spring is controlled to be in an inflated state, the lifting air bags are in a deflated state, the tires at the two ends of the supporting bridge are in contact with the ground, when the ground is fluctuated, the supporting bridge, the guide arm and the through beam move up and down along with the supporting bridge, at the moment, the lifting arm can also freely follow the through beam to move due to the fact that the lifting air bags are in the deflated state, and at the moment, the air bag lifting device does not work; when the heavy truck is in a dead weight state, the air spring is controlled to be in a deflation state, the lifting air bag is in an inflation state, the axial length of the lifting air bag is forcibly prolonged, the lower end of the lifting air bag is fixed on the supporting seat through the supporting arm, the lower end of the lifting air bag cannot relatively displace with the frame, the length of the lifting air bag can only extend upwards, at the moment, the lifting arm can be lifted upwards under the action of the upper end of the lifting air bag, the connecting frame and the through beam are lifted upwards, the end part of the guide arm is connected to the through beam, the supporting bridge is connected with the guide arm, the supporting bridge and the tires at the two ends of the supporting bridge are lifted upwards, and after the supporting bridge is lifted to a certain height, the tires on the supporting bridge are separated from the ground, so that the abrasion of the tires can be effectively reduced, and the oil consumption is reduced;
because the single swing arm air suspension system is a common device in the prior art, considering that the innovation point of the invention is mainly to add the air bag lifting device on the single swing arm air suspension system, the inventor only briefly introduces the single swing arm air suspension system, in the prior art, other devices such as a shock absorber, a transverse thrust rod and the like may also exist on the single swing arm air suspension system, and the detailed structure of the single swing arm air suspension system is not described one by one, and the person skilled in the art can see the prior art.
The beneficial technical effects of the invention are as follows: a single swing arm air suspension system with an air bag lifting device for a non-driving support bridge is provided, and the scheme can lift the non-driving support bridge upwards when a vehicle is in idle load, so that the abrasion of corresponding tires is reduced, and the oil consumption is reduced.
