Balance weight type rear steering forklift

Abstract

The invention discloses a balance weight type rear steering forklift. The balance weight type rear steering forklift comprises a front frame, a rear frame, a working device, a cab, an engine, a torque converter and a gearbox, and is characterized in that the front frame and the rear frame are hinged through a pin shaft, the hinged point is close to rear wheels, and two steering cylinders capable of pushing the rear frame to horizontally rotate relative to the front frame are symmetrically mounted between the front frame and the rear frame; and the working device, the cab, the engine, the torque converter, the gearbox and an upper balance weight are mounted on the front frame, and a lower balance weight is mounted on the rear frame. The balance weight type rear steering forklift is well stressed and is stable to steer after goods are loaded; the view range of a driver is wide, the goods can be accurately and quickly loaded and unloaded, and the working efficiency is high; and multiple functions are achieved.

Description

technical field [0001] The invention relates to a construction machine, in particular to a counterbalanced rear steering forklift. Background technique [0002] Existing engineering forklift trucks, such as the engineering forklift trucks described in the Chinese patents whose application numbers are 200910111391.3 and 201110217317.7, the hinge points of the front and rear frames are all closer to the front wheels, and the steering cylinder assembled between the front and rear frames Push the front frame to rotate horizontally relative to the rear frame to realize front steering; the working device is installed on the front frame, and the cab, engine, torque converter, gearbox and balance weight are installed on the rear frame. When the forklift truck of this project is loaded with goods and turned to drive, the front drive axle is subjected to an additional lateral force, which increases the force on the inner tire of the steering, the frame tilts left and right, and the st...

AI Technical Summary

Problems solved by technology

When the forklift truck of this project is loaded with goods and turned to drive, the front drive axle is subjected to an additional lateral force, which increases the force on the inner tire of the steering, the frame tilts left and right, and the stability of the whole vehicle decreases, especially for heavy loads, partial loads, When turning sharply at high speed, the front drive axle is subjected to a large additional lateral force, which causes the force on the inner tire of the steering to increase sharply, the tire is flattened, the frame tilts left and right, and is very dangerous; the driver installed on the rear frame The chamber and the working device installed on the front frame will rotate each other during operation, and the front and rear distance between the two is relatively large, resulting in poor vision for the driver, thereby reducing the quality of work and work efficiency; in addition, its work function is single
