This application provides an axle structure, chassis device, and lawnmower, belonging to the technical field of vehicle chassis devices. The axle structure includes an axle body and a swing arm part. The axle body includes an axle seat and an axle body, with the axle body supported on the axle seat and pivotally connected to the axle seat. The swing arm part includes two swing arms, which are respectively disposed on opposite sides of the axle body. Both swing arms are pivotally connected to the axle body, and both swing arms can swing relative to the axle body within a set angle range. When the wheel connected to the two swing arms is supported on the road surface, both swing arms can swing to a position abutting against the axle body. The axle structure provided in this application, by setting both swing arms to be pivotally connected to the axle body and setting the axle body to be pivotally connected to the axle seat, allows the axle structure to move to a stable state where both swing arms can abut against the axle body when driving on a road surface with potholes. This ensures that the wheel connected to the axle structure has sufficient traction and prevents slippage.

The application provides a vehicle axle structure, a chassis device and a mower, and belongs to the technical field of vehicle chassis devices. The vehicle axle structure comprises an axle body part and a swing arm part. The axle body part comprises an axle seat and an axle body. The axle body is supported on the axle seat and is pivotally connected to the axle seat. The swing arm part comprises two swing arms, which are arranged on opposite sides of the axle body respectively. Both of the swing arms are pivotally connected to the axle body and can swing within a set angle range relative to the axle body. When wheels connected to the two swing arms are supported on a road surface, both of the swing arms can swing to a position abutting against the axle body. The vehicle axle structure provided by the application is characterized in that both of the swing arms are pivotally connected to the axle body and the axle body is pivotally connected to the axle seat. When the vehicle runs on a road surface with pits, the vehicle axle structure can be moved to a stable state in which both of the swing arms abut against the axle body. Thus, the wheels connected to the vehicle axle structure can have sufficient grip on the road surface, and the wheels can be prevented from slipping.

The present invention discloses a lifting device with adjustable load-bearing capacity, comprising a fixed frame, a support leg is fixedly connected to the outer wall of the bottom of the fixed frame, a motor is fixedly connected to the top of the fixed frame, a sprocket is fixedly connected to the front of the motor through a coupling, a gearbox is arranged on the right side of the sprocket, a chain is drivingly connected to the outer wall of the sprocket, one end of the chain runs through the gearbox, the bottom of the gearbox is fixedly connected to the top of the fixed frame, and an automatic load-bearing stabilization mechanism is arranged inside the fixed frame, which relates to the technical field of cranes. The lifting device with adjustable load-bearing capacity, by arranging an automatic load-bearing stabilization mechanism, maintains the overall balance of the fixed frame and the support leg when different weights are pressed down, avoids the situation that the fixed frame and the support leg tilt and overturn when the rope is lifted by overloaded cargo, and then automatically adjusts its own load-bearing capacity according to the cargo, and greatly improves the stability.
