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 pivot counterweight motor-driven forklift steeraxle devices.
Background technology
In existing fork truck technology, turning to bridge type formula is an important system of four pivot counterweight motor-driven fork trucks, at present, four pivot counterweight motor-driven fork trucks on market adopt a welding pontic mostly, one double cropping pair goes out rod oil cylinder, two steering linkages, two hubs, two wheels are arranged symmetrically with structure, although simple in structure, but in the process of fork truck operation, first, the friction force on wheel and ground is larger, thereby while making to turn to, steering cylinder not only will overcome the friction of rolling that whole mechanism produces, also to overcome friction of rolling and cliding friction that wheel and ground produce, especially fork truck pivot stud cliding friction, secondly, this structural arrangement causes two wheel flutters apart from larger, under equal condition, the operation turn radius of fork truck is larger, again, because this structure causes fork truck cliding friction on wheel and ground when turning to larger, thereby also can be larger to the wearing and tearing of wheel.
Summary of the invention
The object of the invention is exactly in order to make up the defect of prior art, and a kind of large-tonnage four pivot counterweight motor-driven forklift steeraxle devices are provided.
The present invention is achieved by the following technical solutions:
A kind of large-tonnage four pivot counterweight motor-driven forklift steeraxles, include pontic soldering member and wheel flutter assembly, described pontic soldering member comprises back axle top board, back axle top board surface has two mounting holes, the both sides of back axle top board are installed with back axle riser, the symmetrical mounting hole that has on back axle riser, and main shaft is arranged on back axle riser through two mounting holes, on the lower surface of back axle top board, be fixed with limiting stopper and cylinder support, limiting stopper is arranged on a side of cylinder support; Wheel carrier rotating shaft on wheel carrier top board in described wheel flutter assembly is arranged on back axle top board by flange jigsaw through the mounting hole on back axle top board, the both sides of wheel carrier top board are installed with wheel carrier riser, on wheel carrier riser, have mounting groove, the two ends of wheel carrier top board are provided with side brace panel; In the mounting groove of described wheel carrier riser, wheel shaft is installed, wheel outer shaft sleeve is equipped with bearing, and bearing outside is equipped with wheel; Between described two wheel flutter assemblies and back axle top board, be separately installed with active steering dish and driven steering handwheel, between active steering dish and driven steering handwheel, by Linkage steering, connect, connecting lug on active steering dish, connecting lug be connected with piston end steering cylinder, the other end of steering cylinder is arranged on cylinder support.
Between described back axle top board and back axle riser, wheel carrier top board and wheel carrier riser, be and be welded and fixed; Described steering cylinder is connected on cylinder support by bearing pin.
Advantage of the present invention is: operation function of the present invention is except equally may realizing with general forklift steering bridge and turning to, its advantage is compact conformation, can realize less turn radius, the application force of oil cylinder while having reduced to turn to, reduce the friction on wheel and ground, strengthened the back axle load ability of four pivot counterweight motor-driven fork trucks.
