A trailer capable of switching different track travel modes and using method thereof

Abstract

The invention discloses a trailer capable of switching different track travel modes and a method for using the same, comprising a pre-pressure-dissolved carbon dioxide micro-pressurized clutch device, a self-weight return hydraulic shift drive device, a double-track switching device and a hydraulic bionic shift spider Leg-shaped top support structure. The technical field of the cargo trailer of the present invention specifically refers to a trailer capable of switching different track travel modes and a method of using the same; the present invention enables the trailer to switch two different track travel modes through the structure capable of switching the driven track wheels, thereby overcoming the need for It eliminates the technical bias that the same track can only be paved according to one type, so that the appropriate paving mode can be selected according to the function when the track is paved, which greatly reduces the paving cost. The device controls the locking of the large double-track switching device with a very small driving force, and through the adaptive locking structure, the outer ring groove of the track wheel and the I-shaped track are always kept in a good locking state.

Description

technical field [0001] The invention belongs to the technical field of cargo trailers, and specifically refers to a trailer capable of switching between different track travel modes and a method for using the same. Background technique [0002] A trailer refers to a vehicle that is towed by a car and has no power drive itself. It is a combination of a car (truck or tractor, forklift) and one or more trailers. It has the advantages of speed, mobility, flexibility, and safety. It is convenient to realize section transportation. When the trailer is transported in the factory, it generally walks on the track. The track transportation has the advantages of being able to drag multiple vehicles and having good consistency. There are two common track forms. One is that the track wheels are embedded in On the track, the other is that the track wheel is embedded in the track, and the track wheel is embedded in the track. Since there is no complete limit between the track and the wheel...

AI Technical Summary

Problems solved by technology

[0005] Due to the heavy load of the trailer, the strength of the clutch lever is extremely high, so the size of the clutch lever is relatively large. If the clutch lever is directly driven, a relatively high-power motor is required. In order to control the large clutch lever with a small-power motor Movement, the present invention creatively proposes a pre-pressure-soluble carbon dioxide micro-supercharged clutch device, which controls the physical and chemical reactions in the micro-boosted pump box through a small-power motor, and drives the pneumatic piston-type clutch lever through a sharply increased air pressure. Retraction, the pressure-soluble micro booster device uses the principle of intermediary (temporarily combining one object with another easy-to-remove object), temporarily dissolves the carbon dioxide gas used for driving in water, and the two quickly decompose after stirring , through the increased air pressure to drive the pneumatic piston clutch lever, which solves the common problems of large volume, high power and high cost of the active air pump; the electromagnetic lever clutch lever locking device uses the principle of mechanical system replacement to solve the traditional mechanical The structure of the locking device is complex, there are many friction parts, and it is easy to get stuck; the traditional hydraulic motor is replaced by the self-weight return hydraulic shift drive device, which drives the shift center to rotate with the main shaft. The structure is simple, compact, and easy to maintain. The symmetrically arranged self-weight backflow hydraulic shift drive device drives the shift center linkage spindle to rotate in two directions respectively
