Abstract

The invention discloses a dual-power driving system configuration for an electric tractor. The system comprises a rear power output shaft PTO transmission box, a rear axle differential, a rear deceleration transfer integrated box, a front axle driving motor, a front axle differential, a front deceleration box and a rear axle driving motor. Various defects of fuel energy can be overcome, existing limitation of insufficient power caused by a single motor can be broken through, high-housepower output is realized, and high power output needs are met; the dual-power driving system configuration canrealize two functional forms, namely functions of independent PTO and dependent PTO, of PTO output of the electric tractor, and an electric tractor with a single-drive motor does not have this characteristic; due to distributed control of the dual-motor configuration, front drive, rear drive and four-wheel drive operation conversion can be realized according to different agricultural working condition needs, and sliding during field operation can be reduced effectively.

Description

technical field [0001] The invention relates to the technical field of electric tractor power systems, in particular to a configuration of a dual-mounted power drive system for electric tractors. Background technique [0002] In the field of agricultural machinery that uses fuel as energy, agricultural machinery including tractors are subject to many disadvantages of fuel energy, and it is urgent to develop a new energy tractor to meet the needs of farming operations. At present, the existing tractors on the market that use the drive motor as the power source solve the dependence on fuel energy, but they all use the form of a drive motor. The drive system configuration cannot provide a large enough power output. Meet the power demand of high-horsepower tractors. In light of this situation and its background, the present invention provides a dual drive system configuration for an electric tractor. Contents of the invention [0003] The technical problem to be solved by th...
