Description

Technical Field

[0001] The utility model belongs to the technical field of armored vehicles, in particular to a chassis suspension of an armored vehicle. Background Art

[0002] Since tracked vehicles can adapt to a variety of complex terrains and have excellent off-road performance, tracked vehicles are widely used in various engineering vehicles or armored vehicles. For example, the patent document with publication number "CN117818783A" discloses an intelligent tracked robot walking mechanism with stable obstacle crossing. The tracked robot walking mechanism is assembled on the side of the mecha, and guide gears are rotatably installed on the left and right sides of the outside of the mecha, and supporting wheels are rotatably installed on the lower part of the outside of the mecha, and track chains are installed on the outer sleeves of the guide gears and supporting wheels, and tooth blocks are fixed on the inner side of the track chain; it includes: an obstacle crossing auxiliary mechanism, whose side is rotatably installed on the side of the mecha through a control shaft, and the obstacle crossing auxiliary mechanism is autonomously driven and adjusted according to changes in the terrain where the robot walks; a walking shock-absorbing mechanism, which is connected and arranged on the outer side of the supporting wheels, and the supporting wheels are correspondingly distributed front and back. The walking mechanism of the intelligent crawler robot with stable obstacle crossing adopts the patented technical solution, so that obstacle crossing roller support structures are set on the front and rear sides of the track chain. The roller support structures can be adjusted autonomously according to the height of the obstacle slope to keep the robot walking stably over obstacles.

[0003] However, existing armored vehicle chassis suspensions such as Figure 1 As shown, the armored vehicle generally comprises a chassis (1), a crawler (2), a plurality of crank arms (3), a plurality of supporting rollers (4) and a plurality of independent shock absorbers (11), wherein the supporting roller (4) is hinged to one end of the crank arm (3), and the other end of the crank arm (3) is hinged to the chassis (1). A driving wheel (6) is also provided on the chassis (1), and the crawler (2) is wound around the outer circumference of the driving wheel (6) and the outer circumference of the supporting roller (4). One end of the independent shock absorber (11) is hinged to the supporting roller, and the other end of the independent shock absorber (11) is hinged to the chassis (1). When the armored vehicle is traveling on a flat ground, the weight of the armored vehicle itself is shared by a plurality of supporting rollers, thereby ensuring that the armored vehicle travels smoothly. However, when the armored vehicle crosses a ground obstacle, if the size of the obstacle is smaller than the length of the vehicle body, some supporting rollers will be suspended, so that the weight of the armored vehicle itself can only be borne by the remaining supporting rollers, resulting in the load of individual supporting rollers exceeding their own load limit, which poses a great safety hazard. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an armored vehicle chassis suspension.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides an armored vehicle chassis suspension, comprising a chassis, a crawler track, a plurality of crank arms, a plurality of supporting wheels and a plurality of main linkage shock absorbers, wherein the supporting wheels are hinged to one end of the crank arm, and the other end of the crank arm is hinged to the chassis, a driving wheel is also provided on the chassis, the crawler track is wound around the outer peripheral surface of the driving wheel and the outer peripheral surface of the supporting wheel, one end of the main linkage shock absorber is hinged to the crank arm, and the other end of the main linkage shock absorber is hinged to the chassis.

[0007] The armored vehicle chassis suspension also includes a secondary linkage shock absorber, one end of which is hinged to the crank arm, and the other end of which is hinged to the supporting wheel.

[0008] The difference between the number of the supporting wheels and the number of the secondary linkage shock absorbers is 1.

[0009] The chassis suspension of the armored vehicle also includes an auxiliary shock absorber, one end of which is hinged to the supporting wheel, and the other end of which is hinged to the chassis.

[0010] The number of the auxiliary shock absorbers is 2, and the two auxiliary shock absorbers are arranged at the front and rear ends of the chassis.

[0011] The number of the crank arms, the number of the supporting wheels, and the number of the main linkage shock absorbers are equal, and the crank arms, the supporting wheels, and the main linkage shock absorbers are connected in a one-to-one correspondence.

[0012] The number of the crank arms, the number of the track wheels or the number of the main linkage shock absorbers is a positive integer greater than 3.

[0013] The armored vehicle chassis suspension also includes a sprocket wheel, and the track is also wrapped around the outer peripheral surface of the sprocket wheel.

[0014] The supporting sprocket is arranged above the chassis.

[0015] The chassis is also provided with a tension wheel, which is arranged at the front and rear ends of the chassis together with the driving wheel, and the crawler track is also wound around the outer peripheral surface of the tension wheel.

[0016] The beneficial effect of the utility model is that: by adopting the technical scheme of the utility model, a linkage shock absorber is set to make two adjacent supporting wheels interconnected. When the armored vehicle crosses a ground obstacle, if the size of the obstacle is smaller than the length of the vehicle body, even if some supporting wheels are suspended in the air, the supporting wheels that bear the huge weight of the vehicle body will transfer part of the weight of the vehicle body to other supporting wheels through the linkage shock absorber, so that the weight of the armored vehicle itself is shared by all supporting wheels, avoiding the load supported by individual supporting wheels exceeding their own load limit, reducing safety hazards, and ensuring the reliable driving of the armored vehicle.
