Problems solved by technology

Therefore, the intermediate transmission type with complex structure and inconvenient maintenance and repair has been gradually replaced by the side transmission type.
According to market research, we found that the side drive structure used with wheeled tractors with medium horsepower and above can only achieve a single operation item and working direction
To sum up, the existing transmission mechanism used with wheeled tractors with medium horsepower and above cannot realize multiple compound operations, so it cannot meet the needs of modern agricultural production and agronomic requirements

Abstract

The invention provides a transmission gear case for wheeled tractors and relates to a gear case working cooperatively with a wheeled tractor. The transmission gear case comprises a case body on which an input shaft, output shafts and a shifting member are arranged, and a bevel gear assembly, a transition gear and a double gear, which are arranged on the shafts. The invention is characterized in that the at least two output shafts are provided, including an output shaft I and an output shaft II, wherein the output shaft I and the output shaft II are arranged in parallel; the input shaft is arranged vertically to the output shafts; and the input shaft, the output shaft I and the output shaft II are in the same plane. In the invention, the output shaft I is used as both the output shaft and a shifting transition shaft, so that the structure is simplified greatly, the consumption of parts is minimized, both the cost and the power consumption are reduced, and the maintenance and repair of the machine is facilitated. The output directions of the two output shafts are different from each other, and the output speed of the output shafts is adjustable, so that the invention can meet the requirement for various agricultural operations under different working environments.

Description

Technical field [0001] The invention relates to a gear box for matching operation of a wheeled tractor, in particular to a speed change gear box used for matching with a wheeled tractor with a medium horsepower or above. Background technique [0002] At present, the transmission mechanisms used with wheeled tractors above medium horsepower are divided into two categories: one is the transfer structure, which is composed of an independent gearbox and an independent transmission box; the second is the integral structure, that is, the gearbox and The transmission case is combined into a whole. Among them, the integral structure is mostly intermediate transmission. This integral structure can only achieve one farming speed and complete one working direction of rotation, and the phenomenon of missing tillage and less tillage will occur in the lower part of the middle box, and it is necessary to install a small Plow with for. Therefore, the intermediate drive type with complex s...
