Balance type rear wheel drive forklift automatically adjusting center of gravity

Abstract

The invention discloses a balance type rear wheel drive forklift automatically adjusting the center of gravity. The balance type rear wheel drive forklift comprises a cab, a fork arm carrier, a front forklift frame, a rear forklift frame, an engine, a torque converter, an oil tank, a movable upper balance weight, a lower balance weight and a center of gravity adjusting and controlling center. The front forklift frame and the rear forklift frame are hinged through an upper hinge pin and a lower hinge pin. Hinge points are close to rear wheels. A gravity sensor is arranged in the hook-connection position of a forklift accessory and the fork arm carrier and is connected with the center of gravity adjusting and controlling center and the movable upper balance weight through electrical signals. The movable torque converter capable of providing power is connected to the side face of the movable upper balance weight on the front forklift frame, and the lower portion of the movable upper balance weight on the front forklift frame is connected with a movable sliding rail reducing the moving friction force of the upper balance weight. Due to the fact that the forklift is provided with the upper balance weight automatically moving front and back through the torque converter according to goods gravity sensed by the forklift accessory, the technical effect of automatic adjustment of the center of gravity of the whole forklift, and safety during working and driving is ensured effectively.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a balanced rear wheel drive forklift truck with automatic center of gravity adjustment. Background technique [0002] The vigorous development of modern industry has led to the rapid progress of the engineering field. The use of loading devices in the engineering field has been very extensive. Engineering forklift trucks are widely used in wharfs, stone blocks, stone mining areas, logistics distribution centers, etc. . [0003] Most engineering forklift trucks are driven by front wheels, such as the engineering forklift trucks described in the Chinese invention patents with publication numbers CN200910111391.3 and CN201110217317.7, the hinge points of the front and rear frames are all closer to the front wheels The steering cylinder assembled between the front and rear frames pushes the front frame to rotate horizontally relative to the rear frame to achieve front steering; ...

AI Technical Summary

Problems solved by technology

The balance weight of the forklift truck is fixed at the rear of the whole vehicle, so when the forklift truck is driving with no load, the center of gravity is too far behind and easy to turn over; when the forklift truck is performing forklift work, the center of gravity of the whole vehicle Changes with the weight of the forklifted goods, easy to roll over and roll over

Can not effectively guarantee the safety of the working process and driving process
