Description

Technical Field

[0001] This utility model relates to the field of tracked chassis, and more specifically to a tracked mobile chassis. Background Technology

[0002] Construction machinery chassis can be divided into tracked mobile chassis and wheeled mobile chassis based on their walking mechanisms. Wheeled mobile chassis offer advantages such as high flexibility, high speed, and easy operation, enabling smooth and rapid movement on flat terrain. Tracked mobile chassis perform better in complex terrain, on slopes, and on muddy roads.

[0003] Existing tracked mobile chassis are more cumbersome and have poorer impact resistance than wheeled mobile chassis, making it difficult to meet the requirements of high-speed driving exceeding 40 kilometers per hour.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problem of poor impact resistance and difficulty in meeting high-speed driving requirements of existing tracked mobile chassis, this utility model provides a tracked mobile chassis. The tracked mobile chassis includes: a mounting beam; a support roller rotatably mounted on the mounting beam; and multiple shock-absorbing structures connected to the mounting beam and the support roller. Each shock-absorbing structure includes a first support arm rotatably connected to the support roller, a leaf spring mounted on the mounting beam, and a connecting seat connecting the leaf spring and the first support arm. The middle portion of the leaf spring is connected to the mounting beam, and its end portion is connected to the connecting seat.

[0006] This utility model discloses a tracked mobile chassis, comprising a mounting beam, a support roller, and a shock-absorbing structure. The shock-absorbing structure connects the mounting beam and the support roller, reducing vibration of the mounting beam and support roller when the chassis is traveling at high speed and the support roller is impacted, thereby enhancing the chassis's impact resistance and vehicle stability. The shock-absorbing structure includes a first support arm, a leaf spring, and a connecting seat. The middle part of the leaf spring is mounted on the mounting beam, with its two ends curving downwards. The first support arm is connected to the support roller. When the support roller is impacted, the impact force is transmitted along the first support arm and the connecting seat to the leaf spring, causing the leaf spring to elastically deform and reducing the impact force on the mounting beam, thus enhancing the mobile chassis's impact resistance and vehicle stability. Through the above-described configuration, this utility model discloses a tracked mobile chassis with a shock-absorbing structure, which can reduce the vibration and impact of the support roller and mounting beam, enhance the mobile chassis's impact resistance and vehicle stability, and meet the requirements of high-speed driving.

[0007] Furthermore, a second arm is provided between the leaf spring and the first arm, with one end of the second arm connected to the first arm and the other end connected to the middle of the leaf spring.

[0008] Furthermore, a fixed seat is provided in the middle of the leaf spring, one end of the second arm is hinged to the first arm, and the other end is hinged to the fixed seat; a rotation damper is provided between the fixed seat and the second arm.

[0009] Furthermore, one of the first support arms is connected to two sets of support rollers, each set of support rollers having two rollers, and the two support rollers are arranged on both sides of the first support arm.

[0010] Furthermore, one of the first arms is connected to two corresponding second arms, and the two second arms are arranged on both sides of the first arm.

[0011] Furthermore, the connecting seat includes a fixing part connected to the leaf spring and a connecting part connected to the first support arm; the connecting part is arranged between the first support arm and the second support arm.

[0012] Furthermore, it also includes a guide wheel, on which a sliding seat is provided; and a tensioner is installed on the mounting beam, the tensioner being connected to the sliding seat.

[0013] Furthermore, a sliding block is installed on the sliding seat, and a slide rail that matches the sliding block is provided on the mounting beam.

[0014] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0015] The shock-absorbing structure connects the mounting beam and the support roller, which can reduce the vibration of the mounting beam and the support roller when the chassis is traveling at high speed and the support roller is impacted, thereby enhancing the chassis's impact resistance and vehicle stability.
