Abstract

The invention discloses a variable-speed drive device for a tractor. The device comprises a main variable-speed device, an auxiliary variable-speed device and a transfer case idle wheel. The main variable-speed device and the auxiliary variable-speed device are sequentially arranged front and back, one end of the main variable-speed device is connected with a tractor front transmission box, one end of the auxiliary variable-speed device is connected with a tractor rear axle, the transfer case idle wheel is connected with a tractor transfer case, through the above arranging manner, power is transmitted to the tractor rear axle, a tractor front axle and a power output shaft, through combination of the main variable-speed device and the auxiliary variable-speed device, 16 gears are achieved,the main variable-speed device adopts a synchronizer to achieve non-park gear shifting, gear shifting impact and gear shifting force are small, work efficiency is high, an auxiliary variable-speed driven shaft in the auxiliary variable-speed device and a small conical gear are whole, a low-gear driven gear and a high and low gear engaging sleeve cantilever are arranged on the front end of an auxiliary variable-speed driven shaft, the structure is compact, and the axial size of the variable-speed device is effectively reduced. A transfer case driving gear is engaged with the idle wheel on a transfer case idle wheel shaft, occupied space is small, and the speed ratio adjusting is convenient.

Description

technical field [0001] The invention belongs to the field of tractors and relates to a variable speed transmission device for tractors. Background technique [0002] At present, various large and medium power tractors produced at home and abroad, in order to meet the needs of different markets and different operations, require a variety of drive train configurations, such as synchronous reversing, power reversing, power shifting, crawling gears and other configurations. It is difficult to provide a general drive train in the prior art, and different drive trains can only be developed to meet these functions. Therefore, in order to effectively reduce manufacturing costs, it is urgent to develop a variable speed transmission device for general-purpose tractors, which is equipped with front boxes with different functional modules to form gearboxes with different functions to meet the needs of the market. [0003] On May 18, 2016, the State Intellectual Property Office announce...
