Description
Technical field
The present invention relates to engineering machinery field, dress pitched by the balanced type rear wheel drive particularly to a kind of automatic adjustment center of gravity
Car.
Background technology
The flourish made rapid progress having driven engineering field of modern industry, loading attachment use in engineering field
The most quite varied, engineering forklift truck is widely applied to enter on harbour, rough stone block field, stone material mining area, logistics distribution center and other places
Row carrying travels.
Engineering forklift truck great majority use front-wheel drive, such as Publication No. CN200910111391.3 and
Engineering forklift truck described in the Chinese invention patent of CN201110217317.7, the pin joint of its forward and backward vehicle frame all relativelys close to
Front-wheel, between forward and backward vehicle frame, the steering cylinder of assembling promotes front frame to horizontally rotate relative to Rear frame and realizes front steering；Its work
Being arranged in front frame as device, driver's cabin, electromotor, torque-converters, change speed gear box, balance weight are arranged in Rear frame.This engineering
When forklift truck loads goods Turning travel, front driving axle, by an additional side force, makes to turn to inside tire stress to increase,
Vehicle frame tilts, whole vehicle stability reduce, particularly heavy duty, unbalance loading high speed racing to time, front driving axle is by one
The biggest additional side force, makes to turn to inside tire stress to surge, and tire is crushed, and vehicle frame tilts greatly, dangerous big；Peace
Can mutually rotate when the driver's cabin being contained in Rear frame and the equipment operation being arranged in front frame plus before and after both
Distance is relatively big, and the visual field causing driver is poor, thus reduces operation quality and work efficiency.
A lot of engineering forklift truck using rear wheel drive currently also occurs, such as Publication No. CN201120205550.9 and
Engineering forklift truck described in the Chinese utility model patent of CN201220273293.7, forward and backward vehicle frame passes through hinge, hinged
Point is near trailing wheel, symmetrical equipped with two steering cylinders that Rear frame can be promoted to horizontally rotate relative to front frame between forward and backward vehicle frame；
Equipment, driver's cabin, electromotor, torque-converters, change speed gear box, upper balance weight are contained in front frame, and lower balance weight is contained in Rear frame
On.This forklift truck car load force-bearing situation is relatively preferable, loads goods Turning travel more steady than the forklift truck of front-wheel drive；Driver
The visual field is good, and accurately, quickly, work efficiency is high for handling goods.
But, in prior art, whether that whole balance weights are arranged on Rear frame is last for front-wheel drive engineering forklift truck
Side, or rear wheel drive engineering forklift truck use double flat weight upper balance weight is contained in before (leading) vehicle frame rearmost, lower balance weight
(auxiliary) vehicle frame rearmost after being contained in.The balance weight of this forklift truck is all integrally fixed at the rearmost of car load, therefore exists when forklift truck
During deadhead operation center of gravity the most easily after turn over；When forklift truck carries out fork dress work, the center of gravity of car load is along with fork loading thing
The change of weight and change, easily before turn over and turn on one's side.Can not effectively ensure the safety of work process and driving process.
Summary of the invention
