Rear drive electric forklift multifunctional wet axle

Abstract

The invention discloses a multifunctional wet axle of a rear-driven electric forklift. The multifunctional wet axle comprises an output axle shaft, one end of the output axle shaft is connected with a planet carrier, a planet gear assembly is connected with an inner gear ring on the other side thereof in a meshed manner, the outer side of the inner gear ring is connected with the inner wall of the inner gear ring, a friction plate, a spacer and a retaining collar are arranged on the inner side of the inner gear ring, the planet gear assembly is connected with a sun gear on the inner side thereof in a meshed manner, the top of one end of the output axle shaft is connected with one end of the sun gear, a return spring is arranged among a pressing sheet, the sun gear and a piston, an inner ring of a sun gear support is connected with one end of a cover, an outer ring of the other end of the cover is connected with one end of a brake cylinder assembly, the other end of the brake cylinder assembly is connected with one end of a pressing rod, and the other end of the pressing rod is connected with one end of the piston through a sliding bearing. The multifunctional wet axle has the advantages of good universality, compact structure, low cost, large space for legs of an operator, long service life and the like.

Description

technical field [0001] The invention relates to a multifunctional wet-type bridge for a rear-drive electric forklift, which is suitable for the optimization of the transmission system, braking system, ergonomics and power source of the forklift, and belongs to the technical field of forklifts. Background technique [0002] As the performance requirements for the longitudinal and lateral stability of the complete machine, high-position carrying capacity, operating comfort, and the turning radius of the complete machine are getting higher and higher. This requires the vehicle to have the characteristics of small front overhang, large battery capacity, small wheel radius, large leg room for the operator, and short wheelbase. The front axle of the electric forklift now has the following disadvantages: (1) dry braking is used. When using small wheels, the brake must be placed outside the rim due to the size limitation of the rim. When it is built in, the outer diameter of the bra...
