Abstract
The utility model discloses a novel rear three-axle semitrailer lifting axle mechanism, which belongs to the technical field of mechanical manufacturing and aims to solve the problem of high oil consumption of a semitrailer in no-load; the utility model comprises a front axle, a middle axle, a rear axle, a lifting axle bracket, a U-shaped bolt, an air spring, a lifting axle base, an air suspension, a tire and a blocking nut; the lifting bridge is characterized in that the lifting bridge base is fixed on the middle bridge through the U-shaped bolt, the air spring is fixed on the lifting bridge base, the top end of the air spring is fixedly connected with the lifting bridge support, one end of the lifting bridge support is fixedly connected with the front bridge through the U-shaped bolt, and the other end of the lifting bridge support is connected with the rear bridge through the U-shaped bolt; when the semitrailer is unloaded, the air pressure in the air spring is increased, so that the air spring is extended, and the heights of the front axle and the rear axle are increased; the utility model has simple structure, smart design and low cost. The oil consumption of the semitrailer in no-load can be effectively reduced.
Description
Technical Field
The utility model relates to the technical field of machine manufacturing, in particular to a novel rear three-axle semitrailer lifting axle mechanism.
Background
When the semitrailer is unloaded, the tires of the rear three axles are in contact with the ground, so that the driving resistance is large, the oil consumption is high, and the tires are worn.
Disclosure of Invention
In order to overcome the technical problem, the utility model provides a novel rear three-axle semitrailer lifting axle mechanism.
The technical scheme of the utility model is as follows: the utility model relates to a novel rear three-axle semitrailer lifting axle mechanism, which comprises a front axle, a middle axle, a rear axle, a lifting axle bracket, a U-shaped bolt, an air spring, a lifting axle base, an air suspension, a tire and a blocking nut, wherein the front axle is connected with the middle axle through the rear axle; the lifting bridge is characterized in that the lifting bridge base is fixed on the middle bridge through the U-shaped bolt, the air spring is fixed on the lifting bridge base, the top end of the air spring is fixedly connected with the lifting bridge support, one end of the lifting bridge support is fixedly connected with the front bridge through the U-shaped bolt, and the other end of the lifting bridge support is connected with the rear bridge through the U-shaped bolt; when the semitrailer is unloaded, the air pressure in the air spring is improved, so that the air spring is extended, and meanwhile, the length of the air spring in the air suspension on the front axle and the rear axle is reduced, so that the heights of the front axle and the rear axle are improved.
Furthermore, two guide rods are arranged on the base of the lifting bridge, and the air spring extends and contracts up and down along the guide rods; and a blocking nut is arranged at the top end of the guide rod and prevents the air spring from being excessively extended.
The utility model has the beneficial effects that:
according to the novel rear three-axle semitrailer lifting axle mechanism, the lifting of the lifting axle mechanism is controlled by utilizing the extension and compression of the air spring; the semitrailer self-locking device is simple in structure, ingenious in design and low in cost, and can effectively reduce oil consumption of the semitrailer in no-load.

Detailed Description
The novel rear three-axle semitrailer lifting axle mechanism of the utility model is described in detail with reference to the accompanying drawings 1 to 3 in the specification.
The utility model relates to a novel rear three-axle semitrailer lifting axle mechanism, which comprises a front axle 1, a middle axle 4, a rear axle 5, a lifting axle bracket 7, a U-shaped bolt 6, an air spring 8, a lifting axle base 9, an air suspension 2, tires 3 and a blocking nut 10; the lifting bridge is characterized in that the lifting bridge base 9 is fixed on the middle bridge 4 through the U-shaped bolt 6, the air spring 8 is fixed on the lifting bridge base 9, the top end of the air spring 8 is fixedly connected with the lifting bridge bracket 7, one end of the lifting bridge bracket 7 is fixedly connected with the front bridge 1 through the U-shaped bolt 6, and the other end of the lifting bridge bracket 7 is connected with the rear bridge 5 through the U-shaped bolt 6; when the semitrailer is unloaded, the air pressure in the air spring 8 is increased, so that the air spring 8 extends, and the length of the air spring in the air suspension 2 on the front axle 1 and the rear axle 5 is reduced, so that the heights of the front axle 1 and the rear axle 5 are increased.
Furthermore, two guide rods are arranged on the lifting bridge base 9, and the air spring 8 extends and contracts up and down along the guide rods. The top end of the guide rod is provided with a blocking nut 10, and the blocking nut 10 prevents the air spring 8 from being excessively stretched.
A novel rear three-axle semitrailer lifting axle mechanism utilizes the extension and compression of the air spring to control the lifting of the lifting axle mechanism. The semitrailer self-locking device is simple in structure, ingenious in design and low in cost, and can effectively reduce oil consumption of the semitrailer in no-load.
The above description is only an embodiment of the present invention, and variations that can be easily conceived by those skilled in the art within the scope of the present invention are also included in the scope of the present invention.
