Abstract

The invention discloses a wheeled tractor gearbox transmission device. The wheeled tractor gearbox transmission device comprises a first gearbox body, a second gearbox body, an input shaft and a second shaft; the first gearbox body is longitudinally divided into a first cavity, a second cavity and a third cavity connected in sequence; the other end of the first gearbox body is fixedly connected with one end of the second gearbox body; a main speed change mechanism and a secondary speed change mechanism are respectively arranged in the second and third cavities; and a climbing speed change mechanism is arranged in one end of the second gearbox body. The gear shifting grade number of the wheeled tractor gearbox transmission device is increased to 64 gear stages to preferably meet different speed change demands of large and medium wheeled tractors under complicated environments. The wheeled tractor gearbox transmission device is portable in gear shifting, comfortable in operation, lower in wear of engaged gear shifting tooth surfaces and stable in transmission, improves the operation flexibility, can preferably meet more complicated operation requirements, realizes agricultural tool compound motions, reduces the labor intensity, and improves the production efficiency.

Description

technical field [0001] The invention relates to a gear shifting device for a tractor, in particular to a gear shifting device for a tractor which can greatly increase the number of gear shifting stages, is stable and has no impact, and is simple and comfortable to operate, and belongs to the technical field of agricultural machinery. Background technique [0002] With the increasing number of operation items and supporting agricultural machinery of wheeled tractors, the degree of their comprehensive utilization continues to increase, and the demand for large tractors (tractor power: 100 horsepower < N ≤ 200 horsepower) is also increasing. The speed at which large tractors replace medium-sized tractors (tractor power: 40 horsepower < N ≤ 100 horsepower) and small tractors (tractor power: N ≤ 40 horsepower) is significantly accelerated. At the same time, it is required to expand the speed range of tractors and increase the number of shift stages. [0003] The existing wh...
