Hydraulic suspension structure of low platform carrier vehicle

Abstract

The invention relates to a hydraulic suspension structure of a low platform carrier vehicle. The hydraulic suspension structure of the low platform carrier vehicle comprises a suspension frame, a suspension oil cylinder, a balance arm, an axle and a wheel component. The suspension frame is connected to the bottom of the vehicle frame of the platform carrier vehicle, the cylinder body of the suspension oil cylinder is connected with the suspension frame, the end portion of the balance arm is connected to the suspension frame, the axle is connected with the other end portion of the balance arm, the wheel component is connected with the axle, the a cylinder rod used for suspending the oil cylinder is connected with the balance arm, the distance from the connecting point of the cylinder body of the suspension oil cylinder and the suspension frame to the bottom of the vehicle frame is 70-80mm, and the distance between the connecting point of the cylinder rod of the suspension oil cylinder and the balance arm and the connecting point of the suspension frame and the balance arm is 205-215mm. The hydraulic suspension structure of the low platform carrier vehicle has the advantages that the structure is reasonable, the volume is small, the bearing capacity is large, under the condition that the bearing capacity is not changed, the height of the carrier vehicle is greatly lowered, so that the passing ability of the carrier vehicle with high goods in a driving process is guaranteed, the whole suspension structure is compact, the outline size is small, the volume is small, the weight is light, and the installation and the maintenance are convenient.

Description

technical field [0001] The invention relates to a hydraulic suspension structure of a low-platform transport vehicle. Background technique [0002] At present, the known large-scale transport hydraulic modular vehicles rely on a tractor to pull the modular vehicles. The height of the platform of the modular vehicles can be raised and lowered by hydraulic suspension. For road sections, such as tunnels and elevated highways, it is necessary to lower the vehicle to pass through. If the goods on the platform are too high, even if the platform of the modular vehicle is lowered to the lowest level, it will not be able to pass. Many on-site solutions are tires. Venting air, destroying the road surface or the height-limiting highway, waiting for the car to pass, and then repairing the road surface and the height-limiting highway, etc., will greatly waste resources and increase the cost. Contents of the invention [0003] The purpose of the present invention is to provide a hydrau...

AI Technical Summary

Problems solved by technology

[0002] At present, the known large-scale transport hydraulic module vehicle is driven by a tractor head, and the platform height of the module vehicle can be raised and lowered by hydraulic suspension. During the entire journey of transporting large items, when traveling to a certain road section, such as tunnels, elevated highways, etc., it is necessary to lower the vehicle to pass through. If the goods on the platform are too high, even if the platform of the module vehicle is lowered At the lowest level, it is impossible to pass. Many on-site solutions are to deflate the tires, damage the road surface or the elevated limit road, wait for the vehicle to pass, and then repair the road surface and the elevated restricted road, etc., which greatly wastes resources and increases the cost.
