Background
When the crawler chassis is used, the crawler is in contact with the ground, and the driving wheel is not in contact with the ground. When the motor drives the drive wheel to rotate, the drive wheel continuously rolls up the track from the rear under the action of the reducer drive torque through the engagement between the teeth on the drive wheel and the track chain, the ground engaging portion of the track applying a rearward force to the ground, which correspondingly applies a forward reaction force to the track, the reaction force being a drive force for propelling the machine forward. When the driving force is sufficient to overcome the walking resistance, the bogie wheels roll forward on the upper surface of the track, thereby causing the machine to travel forward.
Because the thrust wheels are in rigid connection with the chassis, when the vehicle passes through a rugged road surface, the thrust wheels are in rigid contact with the rugged road surface, so that the vehicle is violently jolted and vibrated in the driving process, particularly in the application of agricultural machinery, the ground is mostly uneven, the fault rate of the whole machine is increased, and the service life of the thrust wheels is shortened.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a suspension profile modeling track chassis structure, includes drive wheel, leading wheel, chassis support, thrust wheel and track, drive wheel and leading wheel set up chassis support's upper end both sides respectively, the thrust wheel equipartition is at the chassis support lower extreme, the track cladding is provided with the swing arm between the outside of drive wheel, leading wheel and a plurality of thrust wheel between per two rows of thrust wheels, and the upper end of swing arm is connected with chassis support through the round pin axle, the swing arm is the V type, is provided with damping spring between the wheel carrier of every row of thrust wheel and the chassis support.
As a preferred technical scheme of the utility model, chassis support's upper end is provided with the tow band wheel, and the tow band wheel is located between drive wheel and the leading wheel, the track cladding is in the outside of tow band wheel.
As an optimal technical scheme of the utility model, one side of leading wheel is provided with the straining device who is used for adjusting the track elasticity.
As a preferred technical scheme of the utility model, straining device is the pneumatic cylinder, the one end and the chassis leg joint of pneumatic cylinder, and the work end and the leading wheel of pneumatic cylinder are connected.
Compared with the prior art, the beneficial effects of the utility model are that: this suspension profile modeling crawler chassis structural design is reasonable, thinks about ingeniously, makes the vehicle pass through the rugged road surface through setting up swing arm and damping spring between bogie wheel and chassis support, along with road surface arch or sunken, bogie wheel automatically regulated angle guarantees that track and road surface laminate completely to this reduces violently jolting, the vibrations that appear among the driving process, prolongs the life of bogie wheel.
