Crawler-type swing arm suspension type walking mechanism and crawler vehicle

Abstract

The invention discloses a crawler-type swing arm suspension type walking mechanism and a crawler vehicle. The walking mechanism comprises a spring damping component, one end of the spring damping component is rotationally connected with a first connecting shaft fixed on a vehicle body, and the other end of the spring damping component is rotationally connected with one end of a swing arm through afirst rotating shaft, the other end of the swing arm is rotationally connected with two gear train fixing plates through a second rotating shaft, a second connecting shaft is rotationally installed in the middle of the swing arm, the second connecting shaft is fixed on the vehicle body, the two sides of the swing arm are respectively provided with a tensioning adjuster, the two gear train fixingplates are fixedly connected through a fixed shaft, an idler wheel and bogie wheels are installed between the two gear train fixing plates through a wheel shaft, the idler wheel is connected with a driving wheel through a crawler ring, and the driving wheel is meshed with the crawler ring and is connected with a decelerator fixed on the vehicle body. The crawler-type swing arm suspension type walking mechanism in the invention is simple and compact in structure, the crawler ring is convenient for tensioning adjustment and easy to implement, and the crawler-type swing arm suspension type walking mechanism is good in tensioning and suspension vibration damping performance and capable of being flexibly arranged on the vehicle body.

Description

technical field [0001] The invention relates to a crawler-type swing-arm-suspended traveling mechanism and a crawler vehicle designed based on the crawler-type swing-arm-suspended traveling mechanism, which belongs to the technical field of crawler vehicle traveling mechanisms. Background technique [0002] According to the way of walking, vehicles are mainly divided into wheeled vehicles and tracked vehicles. Both wheeled vehicles and tracked vehicles include a running gear, and the suspended running gear is one of the running gears. [0003] When designing the running mechanism of wheeled vehicles and tracked vehicles, the swing arm can be involved, and the swing arm can play different roles in the vehicle according to actual needs. [0004] In wheeled vehicles, the swing arm can be used to form the suspension (or suspension system), located at the bottom of the front part of the vehicle, and usually plays a role in connecting and supporting the transmission system of the...

AI Technical Summary

Problems solved by technology

In this invention patent, the swing arm realizes the walking switch between the wheels, shoes and legs, but the range of movement (swing) of the swing arm is small, and it cannot automatically tension the track and perform the function of suspension and vibration reduction. , the track tension cannot be adjusted accurately, and the swing arm has the disadvantages of complex structure and poor practicability

[0008] At present, the suspension system, tensioning system, and running mechanism of tracked vehicles are designed and installed separately, which can easily lead to complex structures, cumbersome installation, poor reliability, and time-consuming and laborious maintenance.
