Abstract

The invention discloses an electric fork-loft truck, an axle case and a reducer casing cover thereof. An axle hole A, an axle hole B, an axle hole C and an axle hole D are formed in the reducer casing cover. The inner side of the reducer casing cover is a connecting wall connected with a middle case body. A groove A is formed by surrounding of the connecting wall. The outer side of the reducer casing box is provided with a first connecting column, a second collecting column, a third collecting column, a fourth collecting column and a connecting arm. The axes of the axle hole C and the axle hole A are located in a plane C. The distance between the axis of the axle hole C and the axis of the axle hole A is d. The plane C is a horizontal plane. The axle hole D is arranged on the rear-upper portion of the axle hole A. The horizontal distance between the axle hole D and the axle hole A ranges from 100 percent to 110 percent d. The vertical distance between the axle hole D and the plane C ranges from 40 percent to 50 percent d. The axle hole B is arranged below the plane C. The horizontal distance between the axle hole B and the axle hole A ranges from 45 percent to 55 percent d. The vertical distance between the axle hole B and the plane C ranges from 5 percent to 15 percent d. According to the installing structure and the transmission structure of the axle case, the structure, the position arranging and other aspects of parts are optimized.

Description

technical field [0001] The invention relates to an electric forklift, an axle box and a reduction box cover 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 a...
