All-terrain high-speed telescopic arm forklift truck

Abstract

The invention discloses a motor arranged on an automotive chassis, which is connected with a hydraulic mechanical combined transmission box through a hydraulic clutch mechanism and a mechanical clutch mechanism. The upper part of the front end of the hydraulic mechanical combined transmission box is provided with a variable pump and a triple gear working pump, and the lower part of the front end of the hydraulic mechanical combined transmission box is provided with a variable motor; the variable pump is connected with the variable motor through a hydraulic rubber pipe; the left side of the lower part of the front end and the rear end of the hydraulic mechanical combined transmission box is provided with a front transmission shaft and a rear transmission shaft, wherein the front transmission shaft is connected with a front axle, and the rear transmission shaft is connected with a rear axle; and the connection position of the front transmission shaft and the hydraulic mechanical combined transmission box is provided with an axle releasing mechanism. The adopted hydraulic mechanical combined transmission box has hydraulic transmission at a low speed, mechanical transmission at a highspeed, maximum running speed of 80 km / h and double characteristics of engineering machinery and an automobile, not only meets the operation characteristics of four-wheel turn and four-wheel drive of the low-speed engineering machinery, but also has the high-speed running functions of two-wheel turn and two-wheel drive of the automobile.

Description

technical field [0001] The invention belongs to special material handling equipment, in particular to an all-road high-speed telescopic arm forklift. Background technique [0002] Container transportation of materials is one of the methods widely used in the world. When the container is delivered to the destination, the materials in the container need to be unpacked and moved, which requires the use of construction machinery and equipment such as telescopic forklifts. For special-purpose large-scale and long-distance two-site loading and unloading of materials in containers, the equipment used --- telescopic arm forklift trucks must have the ability to quickly transfer, and must be able to keep up with the 80km / h speed of the general transport fleet. At the same time, the telescopic forklift must have strong field operation capabilities and all-road operation functions. To make the telescopic forklift complete the above requirements, the telescopic forklift must have both co...

AI Technical Summary

Problems solved by technology

[0004] The structural characteristics of existing ordinary telescopic forklift trucks are mainly manifested in: the bridge and the frame are directly connected, there is no damping system, most of them have two-wheel / four-wheel steering functions and two-wheel / four-wheel drive functions, and the transmission system Generally, hydraulic or hydraulic transmission is used. Hydraulic transmission requires frequent gear shifts during the working process, and the operating comfort is not good. Hydraulic transmission has fewer gears and high operating comfort, but the transmission efficiency is low when driving in transition. Due to the transmission and vibration reduction Affected by other factors, the maximum self-driving speed of ordinary telescopic forklifts is only about 30km / h, and the maximum self-driving speed of all-road telescopic forklifts for field use is about 40km / h. The traveling speed of the transport convoy, therefore, cannot fulfill the requirements of a large-scale and long-distance fast maneuvering transition between two places
