Embodiment 1

[0042] combine figure 1 and figure 2 , a tracked vehicle chassis for high-speed travel in this embodiment includes a support mechanism 1, a running mechanism 2, a damping mechanism 3, a tension mechanism 4 and a drive mechanism 5, and the support mechanism 1 includes a main beam 11 and connecting plate 13, the two form an integrated structure for supporting the vehicle, other mechanisms for fixing the vehicle chassis, the running mechanism 2 includes crawler belts 21 and a plurality of running wheels, the running wheels are connected to the supporting mechanism 1 through the damping mechanism 3, and the supporting The supporting wheel 14 of the mechanism 1, the running wheel of the traveling mechanism 2, the tensioning wheel 41 of the tensioning mechanism 4 and the driving wheel of the driving mechanism 5 jointly support the crawler belt 21, and travel under the driving of the driving mechanism 5.

[0043] The driving wheel in the present embodiment adopts shaft-shaped drivi...

Embodiment 2

[0051] combine Figure 5 and Figure 6 , the drive mechanism 5 of this embodiment is applied to a crawler vehicle chassis for high-speed travel described in Embodiment 1. In order to make it have a higher speed, a high-speed hydraulic motor is selected, but the hydraulic motor is not currently Applied to the drive of tracked vehicles without the motor output shaft commonly used in track drives. And the common driving wheel on the market is usually a toothed wheel, which is directly connected with the output shaft of the hydraulic motor to realize rotation. The high-speed hydraulic motor without output shaft used in this embodiment cannot find a suitable driving wheel on the market. In this embodiment, the driving mechanism 5 is comprehensively designed in combination with the characteristics of the high-speed motor and the toothed track.

[0052] The drive mechanism 5 includes a motor 51, a transition plate 52, an extension tube 53, a drive wheel plate 1 54, a drive wheel pl...

Abstract

The invention discloses a crawler-type vehicle chassis for high-speed travel, and belongs to the technical field of chassis frame design and manufacture. Including supporting mechanism, traveling mechanism, damping mechanism, tensioning mechanism and driving mechanism, the driving mechanism adopts shaft-shaped driving wheel, cooperates with rubber toothed track and high-speed hydraulic motor to travel at high speed; the traveling mechanism includes end traveling wheel and middle traveling wheel , are connected to the supporting mechanism through the damping springs of the damping mechanism and the damping side plates. The damping mechanisms at both ends can drive the wheels to move, buffering the recoil force obliquely downward, and at the same time have a damping effect. The damping mechanism in the middle The vibration mechanism can reduce the vibration in the vertical direction, and there are two pairs of road wheels in the middle, so that the center of gravity of the vehicle is more stable; the tensioning mechanism tensions the track, and under the drive of the driving mechanism, each wheel cooperates to make the vehicle run stably . In addition, a limit groove is provided under the end traveling wheel to correct the relative position of the track and the wheel, further ensuring the stable driving of the vehicle.

Description

technical field [0001] The invention relates to the technical field of chassis frame design and manufacture, and more specifically, relates to a tracked vehicle chassis for high-speed travel. Background technique [0002] At present, crawler drive is used in all aspects of engineering vehicles. The crawler-type traveling mechanism drives and supports the rotation of the crawler through the driving wheel and the driven wheel. It has the advantages of small size, strong adhesion, and good driving ability, and has a strong adaptability to complex terrain, and its application is becoming more and more extensive. [0003] Most of the driving wheels used in the existing crawler-type traveling mechanism are toothed wheels, which are matched with hinged crawler belts, and the wear and tear on the gears is relatively large when walking, and the vibration resistance when walking fast in this way is relatively general; at the same time , the drive wheels on the market are often direct...
