Description

Drive wheel assembly of an electric forklift

technical field

The utility model relates to a driving wheel assembly of an electric forklift.

Background technique

The driving wheel assembly of the electric forklift includes a driving frame, a driving motor installed in the driving frame, a driving gear is provided on the output shaft of the driving motor, a transmission shaft is provided in the driving frame, and a first driven gear and a first driven gear are arranged on the transmission shaft. The second driven gear, the driving gear meshes with the first driven gear, there is an inner gear cylinder around the drive motor, the inner gear cylinder is locked on the drive motor through bearings, and an inner gear ring is arranged on the inner wall of the inner gear cylinder. The second driven gear meshes with the inner ring gear, and the inner gear cylinder is covered with rubberized wheels. The disadvantage of the existing electric forklift driving wheel assembly is that when the rubber-covered wheel is replaced after being used for a period of time, the replacement is very troublesome because the inner gear cylinder is locked on the driving motor by two bearings.

Contents of the invention

In order to overcome the above shortcomings of the existing electric forklift drive wheel assembly, the utility model provides an electric forklift drive wheel assembly with rubber-covered wheels that can be easily replaced.

The technical scheme for solving the technical problems of the utility model is: a driving wheel assembly of an electric forklift, comprising a driving frame, a driving motor arranged in the driving frame, and a driving gear is arranged on the output shaft of the driving motor, so that The drive frame is provided with a transmission shaft, and the transmission shaft is provided with a first driven gear and a second driven gear, and the driving gear meshes with the first driven gear;

There is a ring of inner gear cylinder on the periphery of the drive motor, the inner gear cylinder is supported on the drive motor through bearings, the inner wall of the inner gear cylinder is provided with an inner gear ring, and the second driven The gear meshes with the inner ring gear;

The inner gear cylinder is covered with a skeleton cylinder, and the rear end of the skeleton cylinder has a circle of positioning ring folded inward, and the positioning ring is located at the rear of the internal gear cylinder and is adjacent to the rear end surface of the internal gear cylinder ;

It also includes a locking screw, and the locking screw is locked into the inner gear cylinder from the positioning ring;

Rubberized wheels are sheathed on the skeleton cylinder.

Further, the outer surface of the skeleton cylinder is provided with a mounting convex ring; the rubberized wheel is a rubber wheel, and the inner wall of the rubber wheel is provided with a mounting groove adapted to the mounting convex ring, and the After the rubberized wheel is put on the skeleton tube, the installation protruding ring is embedded in the installation groove.

The usage method of the utility model is the same as the usage method of the existing electric forklift drive wheel assembly, all of which drive the transmission shaft to rotate through the drive motor, and then drive the inner gear cylinder to rotate through the second driven gear, and the rotation of the inner gear cylinder Drive the skeleton cylinder to rotate, and then drive the rubberized wheel to rotate.

The beneficial effect of the utility model is that: the rubber-coated wheel is installed on the transmission assembly through a frame tube, and the frame tube is fixed on the inner gear tube through a locking screw. When the rubber-coated wheel needs to be replaced, only the locking screw needs to be disassembled , the skeleton tube together with the rubberized wheel can be removed for replacement.
