A Herringbone Forest Roulette with Self-pretensioning and Buffering

Abstract

The invention relates to a self pretightening buffering herringbone forest wheel disc and belongs to the technical field of forest vehicle chassis. The forest wheel disc comprises wheels and a base disc. Each wheel comprises a herringbone wheel bone and a self pretightening buffering device. The herringbone wheel bones are installed on two sides of the middle of the base disc, two arms at the bottom are wheel arms, the wheels are installed on the end portions of the wheel arms, a top single arm is a traction arm, and the self pretightening buffering devices are installed on the traction arm. A wheel bone outer casing and a wheel bone inner casing are installed in a matching mode to form an enclosed casing. Direct gears are installed on the end portions of the inner sides of the wheel arms of the two casings, direct gears are coaxially installed in the middle of the inner sides of the two casings, and the gears are in meshing transmission through a tooth-shaped meshing belt. The self pretightening buffering device achieves a self pretightening buffering function, achieves wheel arm high-amplitude swinging and restrains the borne materials in the vehicle cross-country running process. The wheel disc can improve the motor-driven country crossing performance of forest vehicles, simplify the vehicle whole structure and improve the vehicle carrying performance.

Description

technical field [0001] The invention relates to a forestry roulette, in particular to a herringbone-shaped forestry roulette with self-pretensioning and buffering, and belongs to the technical field of forestry vehicle chassis. Background technique [0002] China has a large land area and is covered by a wide range of forests. The terrain in the forest area is complex and changeable: the ground is rugged, hills and slopes can be seen everywhere, and there are often gullies and swamps on the ground. Therefore, forestry vehicles are prone to rollover, difficulty in overcoming obstacles, and lack of power in the forest area. It is also very difficult for unloaded vehicles to drive freely and smoothly in the forest area. Terrain will be more difficult. Therefore it is very necessary to develop a forestry vehicle with high off-road performance that runs smoothly, is not easy to skid and sinks. [0003] Forestry vehicles need to have extremely high road condition adaptability an...
