Abstract

The invention relates to the technical field of novel tractor cab damping, in particular to a suspension cab damping structure of a wheeled tractor, which comprises a tractor shell and a damping module, an equipment groove is formed in the tractor shell, and the damping module is fixedly connected to the inner wall of the equipment groove. The damping module is fixedly connected with the inner wall of the tractor shell, the damping module comprises an air pump, an air pipe, an energy accumulator, an inflation damper, a cab assembly, a cab connecting frame, a rubber damping block, a cab support, an anti-disengaging pull rod and a frame, and the top end of the frame is fixedly connected with the inner wall of the tractor shell; the top end of the frame is in threaded connection with the bottom end of the cab support, and if the vibration amplitude of the cab is large under special conditions such as running on an uneven road surface, the anti-disengaging pull rod can make contact with the cab support, extrude and buffer the cab support. The secondary damping effect is achieved, the cab connecting frame is prevented from being separated from the cab support, and safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of a novel tractor cab shock absorption, in particular to a suspension cab shock absorption structure of a wheeled tractor. Background technique [0002] The damping structure of the cab of traditional wheeled tractors is relatively simple, more or less adopts the rigid connection of direct contact between metal and metal, and slightly better uses rubber pads for simple damping treatment. As a result, when the tractor is working, the cab is greatly affected by engine vibration, the noise in the cab exceeds the standard, the driver has poor operating comfort and is prone to fatigue. With the improvement of the country's economic level and the increase of agricultural mechanization, the farmers' demand for high-end comfortable tractor cabs has become increasingly strong. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invent...
