Abstract
The invention discloses a steering axle of a large-tonnage four-pivot counterweight motor-driven forklift, which comprises an axle body welding piece and a steering wheel assembly. The axle welding piece comprises a rear axle top plate, two installation holes are arranged on the surface of the rear axle top plate, rear axle vertical plates are fixedly installed on two sides of the rear axle top plate, installation holes are symmetrically arranged on the rear axle vertical plates, a spindle penetrates through the two installation holes to be installed on the rear axle vertical plates, a limit block and an oil cylinder support seat are fixed on the lower surface of the rear axle top plate, and the limit block is installed on one side of the oil cylinder support seat. A wheel frame rotating shaft on a wheel frame top plate of the steering wheel assembly penetrates through the installation hole on the rear axle top plate to be installed on the rear axle top plate through a flange split plate, wheel frame vertical plates are fixedly installed on two sides of the wheel frame top plate, installation grooves are arranged on the wheel frame vertical plates, and lateral reinforcing plates are installed at two ends of the wheel frame top plate. The steering axle has the advantages of being compact in structure and capable of achieving smaller turning radius, reducing oil cylinder action force in steering, reducing friction between wheels and the ground and improving rear axle loading capability of the four-pivot counterweight forklift.
Description
Technical field
The present invention relates generally to a kind of large-tonnage four fulcrum counterbalanced weight electri forklift steeraxle devices.
Background technology
Turning to the bridge type formula in the existing fork truck technology is an important system of four fulcrum counterbalanced weight fork trucks, and at present, four fulcrum counterbalanced weight fork trucks on the market adopt mostly that a welding pontic, a double cropping are two to go out rod oil cylinder, two steering linkages, two hubs, two wheel symmetric arrangement structures; Though simple in structure, in the process of fork truck operation, at first; Wheel and ground-surface friction force are bigger, thereby make when turning to, and turn to oil cylinder not only will overcome the friction of rolling that entire mechanism produces; Also to overcome friction of rolling and cliding friction, especially fork truck pivot stud cliding friction that wheel and ground produce, secondly; This structural arrangement causes two wheel flutters apart from bigger; Under equal condition, the operation turn radius of fork truck is bigger, once more; Because this structure causes fork truck wheel and ground-surface cliding friction when turning to bigger, thereby also can be bigger to the wearing and tearing of wheel.
Summary of the invention
The object of the invention is exactly in order to remedy the defective of prior art, a kind of large-tonnage four fulcrum counterbalanced weight electri forklift steeraxle devices to be provided.
The present invention realizes through following technical scheme:
A kind of large-tonnage four fulcrum counterbalanced weight electri forklift steeraxles include pontic soldering member and wheel flutter assembly, and described pontic soldering member comprises the back axle top board; Back axle top board surface has two mounting holes; The both sides of back axle top board are installed with the back axle riser, on the back axle riser symmetry have a mounting hole, main shaft passes two mounting holes and is installed on the back axle riser; Be fixed with limiting stopper and cylinder support on the lower surface of back axle top board, limiting stopper is installed in a side of cylinder support; The mounting hole that wheel carrier rotating shaft on the wheel carrier top board in the described wheel flutter assembly is passed on the back axle top board is installed on the back axle top board through the flange jigsaw; The both sides of wheel carrier top board are installed with the wheel carrier riser; Have mounting groove on the wheel carrier riser, the two ends of wheel carrier top board are equipped with the side brace panel; In the mounting groove of described wheel carrier riser wheel shaft is installed, the wheel outer shaft sleeve is equipped with bearing, and bearing outside is equipped with wheel; Be separately installed with active steering dish and driven steering handwheel between described two wheel flutter assemblies and the back axle top board; Connect through Linkage steering between active steering dish and the driven steering handwheel; Connect earrings on the active steering dish; The piston end with turning to oil cylinder that connects earrings is connected, and turns to the other end of oil cylinder to be installed on the cylinder support.
It is fixing to be welding between described back axle top board and back axle riser, wheel carrier top board and the wheel carrier riser; The described oil cylinder that turns to is connected on the cylinder support through bearing pin.
Advantage of the present invention is: operation function of the present invention is except that equally possibly realizing turning to general forklift steering bridge; Its advantage is compact conformation; Can realize littler turn radius; The application force of oil cylinder when having reduced to turn to has reduced wheel and ground-surface friction, has strengthened the back axle load ability of four fulcrum counterbalanced weight fork trucks.
