Problems solved by technology

[0002] At present, in my country's electric tractor products, most of them are based on the transmission box of the original diesel tractor, and the interface connected to the engine is slightly modified to be used as the interface of the drive motor, while the internal structure of the transmission box has not changed significantly. , resulting in an unreasonable match between the transmission box and the drive motor, making it difficult to give full play to the characteristics of the stepless speed regulation of the drive motor

Embodiment Construction

[0010] The present invention will be further described below by accompanying drawing. Such as figure 1 As shown, this kind of integrated transmission box device for electric tractor adopts two driving motors and two kinds of transmission devices to provide power for the electric tractor's walking and power output respectively; The lower two sections provide power for the tractor to travel; the travel output shaft 1 of the transmission box leading to the rear axle is shared by the power output transmission device A and the travel transmission device B; the transmission case housing and the rear axle housing are integrated housing 2, And the installation position of the power take-off device D is reserved.

[0011] The travel output shaft 1 at the rear end of the travel transmission device B is connected to the large bevel gear C1 in the rear axle differential device C; the power output front intermediate shaft A3 in the power output transmission device A is connected to the po...

Abstract

The invention discloses an integrated transmission case for a battery powered tractor. The integrated transmission case comprises a power take-off transmission device, a running transmission device, a rear axle differential gear and a power take-off device. A shell of the transmission case is an integrated shell, a running output shaft at the back end of the running transmission device is connected with a bevel gear wheel in the rear axle differential gear, a power take-off front middle shaft in the power take-off transmission device is connected with a power takeoff input shaft in the power take-off device, a duplicate gear in the power take-off transmission device is sleeved on the running output shaft, and a sliding gear sleeve in the running transmission device is arranged on the running output shaft via a spline. The integrated transmission case for the battery powered tractor is clear in transmission path, compact in structure, convenient to operate and meets the need of production and operation of the battery powered tractor. As varieties and quantity of parts are reduced, production cost is lowered.

Description

technical field [0001] The invention belongs to the field of tractors, and relates to an electric tractor, in particular to an integrated transmission box for an electric tractor. Background technique [0002] At present, in my country's electric tractor products, most of them are based on the transmission box of the original diesel tractor, and the interface connected to the engine is slightly modified to be used as the interface of the drive motor, while the internal structure of the transmission box has not changed significantly. , As a result, the matching between the transmission box and the driving motor is unreasonable, and it is difficult to play the characteristics of the stepless speed regulation of the driving motor. With the urgent need to reduce environmental pollution, the development and production of electric tractors are becoming more and more urgent. Therefore, it is necessary to develop a transmission box with a simple and compact structure that matches th...
