Abstract

The invention discloses an electric forklift, an axle box and a lubricating structure of the axle box. In the structure of the axle box, the axis of a transmission shaft of a first gear and the axis of a drive half shaft are located in a plane C, the distance between the transmission shaft and the drive half shaft is d, an input gear is located on the rear upper portion of the drive half shaft, the horizontal distance between the axis of the input gear and the drive half shaft is 100%-110% of d, and the vertical distance between the input gear and the plane C is 40%-50% of d; a duplicate gear shaft is located under the plane C, the horizontal distance between the duplicate gear shaft and the drive half shaft is 45%-55% of d, and the vertical distance between the duplicate gear shaft and the plane C is 5%-15% of d; when the plane C where the axis of the transmission shaft and the axis of the drive half shaft are located is horizontal, the liquid surface in the axle box is higher than the plane C and lower than an upper end of a communication hole. By means of the electric forklift, the axle box and the lubricating structure of the axle box, a differential mechanism assembly, gears and bearings are well lubricated. Besides, a connection sleeve connected with a motor does not need to be sealed.

Description

technical field [0001] The invention relates to an electric forklift, an axle box and a lubricating structure thereof. Background technique [0002] Electric vehicles are widely used due to their low noise, no exhaust, simple maintenance, easy operation, and superior traction performance. However, electric vehicles require a lot of power to provide energy. very critical. The driving system of an electric vehicle includes axles, wheels, frame and suspension, and the driving motor transmits power to the wheels through a reduction box and a drive axle. [0003] The patent document with the publication number CN202944154 discloses an axle box assembly of a battery forklift, which places the drive motor in parallel with the drive axle and transmits power through the transmission, saving space, making the overall structure more compact and the layout more reasonable; At the same time, the adjustable connection of the support plate is used to facilitate the overall processing and...
