Frame system capable of switching connection modes of frame and front axle and switching method of frame system

Abstract

The invention discloses a frame system capable of switching connection modes of a frame and a front axle. The frame system comprises the frame, and the front axle is connected below the front end of the frame through a plate spring; and the frame comprises two longitudinal beams which are arranged in parallel, the left sides and the right sides of the front ends of the two longitudinal beams are each provided with a switching assembly, and the switching assemblies are used for enabling the connection mode between the frame and the front axle to be switched between elastic connection and rigidconnection. The invention further discloses a switching method of the connection mode of the frame and the front axle. The frame and the front axle are connected in the rigid connection mode and the elastic connection mode, elastic connection is adopted when the industrial vehicle runs at a high speed, a good vibration reduction function is achieved, the industrial vehicle reaches an operation area and is switched into rigid connection, and the industrial vehicle has good impact resistance. According to the frame system capable of switching the connection mode of the frame and the front axle,transport vehicles for additionally transporting engineering vehicles are saved, and the cost is saved.

Description

technical field [0001] The invention relates to the field of special industrial vehicles, in particular to a frame system capable of switching the connection mode between the frame and the front axle and a switching method thereof. Background technique [0002] Industrial vehicles are in a low-speed driving state during operation, the frame bears a large load, and most of them are impact loads, the frame and the axle adopt a direct rigid connection method, there is no vibration reduction system, and the self-driving speed of the vehicle itself is relatively low, generally not exceeding 40km / h. However, when carrying out material loading and unloading operations in two places over long distances under certain emergency task conditions, simply relying on low-bed transportation of industrial vehicles will invisibly increase additional equipment and deployment and withdrawal time, which is not conducive to the completion of emergency tasks. If the industrial vehicles are improv...

Problems solved by technology

However, when carrying out material loading and unloading operations in two places over long distances under certain emergency task conditions, simply relying on low-bed transport of industrial vehicles will invisibly increase additional equipment and deployment and withdrawal time, which is not conducive to the completion of emergency tasks. If the industrial vehicles are improved The self-driving speed of the vehicle itself can reach the road speed of more than 80km / h. Without relying on low-bed transportation, industrial vehicles can meet the emergency task requirements of long-distance material loading and unloading operations in two places.
