Universal leveling device for vehicle body

Abstract

The invention relates to a universal leveling device for a vehicle body. The device comprises the vehicle body, an universal joint, a leveling cylinder and a bottom frame; the vehicle body is connected with the bottom frame through the universal joint; two ends of a longitudinal axis of the universal joint are respectively fixed to the vehicle body through a bearing block, and while two ends of a transverse axis of the universal joint are fixed to the bottom frame through another bearing block; the leveling cylinder comprises a front leveling cylinder, a rear leveling cylinder, a left leveling cylinder and a right leveling cylinder; a leveling cylinder body is hinged with the bottom frame; a piston rod is hinged with the vehicle body; an inclination angle sensor that is connected with a storage battery and an encoder is mounted on the vehicle body; the coder is connected with an electronic-control hydraulic valve; the electronic-control hydraulic valve controls the expansion and shrinkage of the front leveling cylinder, the rear leveling cylinder, the left leveling cylinder and the right leveling cylinder. According to the universal leveling device for the vehicle body, the vehicle body and the bottom frame are connected through the universal joint, the vehicle body is supported and leveled under the resistance of the leveling cylinder, and thereby, the vehicle body can be automatically leveled on various uneven roads, the respond is sensitive and quick, and any leveling dead angle is avoided; in addition, the stability of the vehicle body is improved.

Description

technical field [0001] The invention belongs to the field of engineering vehicle leveling equipment, and in particular relates to a universal leveling device for a vehicle body. Background technique [0002] At present, the self-leveling of engineering vehicles is usually simply to realize the lifting and lowering of the vehicle body, and has not yet achieved real-time adjustment according to the actual conditions of the road surface to maintain the levelness of the vehicle body platform. When the road is uneven, the vehicle body will tilt, which will affect the driving comfort and the normal operation of the working devices installed on the vehicle body, and even cause accidents such as the slipping of the transported heavy objects or the overturning of the engineering vehicle. Contents of the invention [0003] The object of the present invention is to provide a universal leveling device for a vehicle body that can realize automatic leveling under various uneven road con...
