Abstract

The invention discloses an electric fork-lift truck, an axle case and a middle case body. The middle case body is provided with an axle hole E, a communication hole, an axle hole F and an axle hole G. One side of the middle case body is a reducing side connecting wall which is connected with a reducer casing cover, and is surrounded to form a groove B. The other side of the middle case body is a differential side connecting wall which is connected with a differential casing cover, and is surrounded to form a groove C. A baffle is arranged between the groove B and the groove C. The axle hole E is arranged on the baffle. The axle hole E and the communication hole penetrate through the groove B and the groove C. The axes of the axle hole F and the axle hole E are placed in a plane C. The distance between the axis of the axle hole F and the axis of the axle hole E is d. The plane C is a horizontal plane. An axle hole G is arranged on the rear-upper portion of the axle hole E. The horizontal distance between the axle hole G and the axle hole E ranges from 100 percent to 110 percent d. The vertical distance between the axle hole G and the plane C ranges from 40 percent to 50 percent d. The upper end of the communication hole is arranged above the plane C, and the lower end of the communication hole is arranged below the plane C. 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 an intermediate box thereof. Background technique [0002] Electric vehicles are widely used because of their noiselessness, no exhaust, simple maintenance, easy operation, and superior traction performance. However, because electric vehicles require a lot of power to provide energy, compared to fuel vehicles, electric vehicles use more space. very critical. The driving system of an electric vehicle includes an axle, wheels, a frame and a suspension, and the drive motor transmits power to the wheels via a reduction box and a drive axle. [0003] The patent document with 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, which saves space and makes the overall structure more compact and more reasonable in layout; At the same time, the adjustable conne...
