Automatic leveling and supporting device for trailer carriage body of snow wax truck

Abstract

The invention provides an automatic leveling and supporting device for a trailer carriage body of a snow wax truck, which comprises trailer supporting legs, a transverse moving supporting leg mechanism and a leveling control mechanism, and the trailer supporting legs are arranged at the bottom of a trailer frame; the transverse moving supporting leg mechanism is arranged on the trailer frame and is in sliding fit with the trailer frame; the transverse moving supporting leg mechanism is used for assisting in supporting the compartment body to extend leftwards and rightwards, and the leveling control mechanism is used for achieving automatic leveling of the carriage body by detecting signals of the sensor. The transverse moving supporting leg mechanism can play an auxiliary supporting role after the carriage body is expanded in the left-right direction, the vehicle overturning risk caused by mass deviation after expansion is prevented, and in the driving process, the transverse moving supporting leg mechanism is reset; the leveling control mechanism can achieve automatic leveling of the supporting legs by monitoring signals sent by the position sensors.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automatic leveling support device for a trailer compartment of a snow wax vehicle. Background technique [0002] The snow wax car is mainly used for waxing the skis during ski competitions. The semi-trailer body is used as a working area for waxing related work, and it is also used as a storage and transportation platform for waxing equipment and snowboards. When serving the event, in order to ensure sufficient waxing work space, the car body needs to be unfolded to obtain the largest possible working area; during the driving process, the specific requirements of road transportation must be met, so the car body needs to be restored to the driving state . When serving events, the snow wax car is often placed in the roadless area near the ski resort, and then the expansion series of the box body is operated. It often brings great hidden dangers to the overturning safety of...

AI Technical Summary

Problems solved by technology

[0003] The support devices in the field of semi-trailers mainly use manual mechanical outrigger auxiliary support, electric outrigger support, hydraulic outrigger, electric + hydraulic outrigger, electric + pneumatic outrigger support, etc., basically do not involve automatic leveling Function, several outrigger mechanisms are directly or indirectly connected to the semi-trailer frame through the connecting structure, which cannot realize the large stroke expansion of the box body (expansion in the left and right directions) and the support of the extended part of the box body hanging on the outside. In addition, the design hydraulic pressure and pneumatic outriggers, both have the problem of micro-leakage, and the reliability of their long-term hover support is poor
