Wheel for automatically controlling speed of hand-pulled forklift

Abstract

The invention discloses a wheel for automatically controlling the speed of a hand-pulled forklift. The wheel comprises a wheel body, a protective cover is mounted on one side of the wheel body; a fixed shaft is integrally connected in the wheel body; the end part of the fixed shaft penetrates through the protective cover; an axis hole is formed in one end, outside the protective cover, of the fixed shaft; a wheel assembly mark is arranged on the other side of the wheel body; a rim is mounted on the inner wall of the wheel body; a positioning frame is mounted on the inner wall of the wheel body; a first friction shoe and a second friction shoe are respectively mounted at two ends of the positioning frame; the first friction shoe and the second friction shoe are symmetrically arranged; friction plates are connected to the outer sides of the first friction shoe and the second friction shoe; the fixing shaft penetrates through the positioning frame, a first balancing weight is installed atthe bottom of the positioning frame, the outer side of the fixing shaft is rotationally connected with a rotating frame through an ejector pin bearing, the outer side of the rotating frame is symmetrically and integrally connected with protruding plates, and the wheel is simple in overall structure and can automatically activate a speed reducer according to the rotating speed of the wheel to achieve the purpose of controlling the vehicle speed.

Description

technical field [0001] The invention relates to the technical field of wheels, in particular to a wheel for automatic speed control of a hand forklift. Background technique [0002] The hand forklift plays the role of transporting materials, and the wheel is an indispensable part of the hand forklift. [0003] Most manual forklifts on the market are not equipped with brakes. Because forklifts often carry heavy objects, when the path of transportation is downhill, the heavy objects will drive the forklift to move faster. This situation has a greater safety hazard. Therefore, we propose a The utility model relates to a wheel used for automatic speed control of a hand forklift. Contents of the invention [0004] The object of the present invention is to provide a wheel for automatic speed control of a hand-hauled forklift, so as to solve the problems raised in the above-mentioned background technology. [0005] In order to achieve the above object, the present invention pro...
