Existing transition disc is when accepting driving engine and being connected with controllable capacity pump, transition apparatus selected by it is the rigid body of monoblock rigid transition dish, because rigid transition dish is monoblock steel material, after fastener is tightened, transition disc then and between controllable capacity pump castellated shaft, form a steel body, when rigidity transition disc splined hole and controllable capacity pump castellated shaft disalignment or when assembling not in place, high engine speeds is rotated, very easily twist off controllable capacity pump castellated shaft or damage controllable capacity pump, losing huge.
Summary of the invention
The utility model is the transition disc steel body of monoblock for the transition apparatus on existing fork truck, and it is when High Rotation Speed, easily twists off the problem of controllable capacity pump castellated shaft or damage controllable capacity pump, provides a kind of fork truck flexible transition dish device.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Fork truck flexible transition dish device, comprise controllable capacity pump and engine flywheel, also comprise and being connected with the transition disc of engine flywheel for link variable pump, transition disc comprises the steel loop be fixed on engine flywheel and the rotating disk be fixed on steel loop, through hole is provided with in the middle part of rotating disk, through hole is embedded with spline housing, and controllable capacity pump inside is provided with the castellated shaft in end insertion spline housing.
Transition disc for filtering link variable pump and driving engine adopts steel loop, rotating disk and spline housing combination to form, avoid because of transition disc be monoblock rigidity dish and and form a steel body between controllable capacity pump castellated shaft, then effectively reduce when High Rotation Speed, the situation that controllable capacity pump castellated shaft twists off or controllable capacity pump damages.
As preferably, engine flywheel outer rim is provided with clutch bell, clutch bell is fixed with transition disc shell.Respectively certain protective effect is carried out to engine flywheel and transition disc by clutch bell and transition disc shell; transition disc shell also plays a positioning action to controllable capacity pump simultaneously; make the installation of controllable capacity pump more accurate, also make controllable capacity pump reduce castellated shaft when High Rotation Speed by the probability twisted off simultaneously.
As preferably, in the middle part of transition disc shell, be configured for the recessed seam of controllable capacity pump location.By this recessed seam, controllable capacity pump is first positioned, make the installation of controllable capacity pump more accurate, also substantially increase the efficiency of assembling of controllable capacity pump simultaneously.
As preferably, engine flywheel is provided with dowel hole, and steel loop is fixed on engine flywheel by binding bolt and locating dowel pin.Steel loop is first located on engine flywheel by locating dowel pin, and then fastening by binding bolt, can make on the one hand the assembling of steel loop more efficiently, more accurate; Also the twisting resistance of bolt can be improved on the other hand to a certain extent.
As preferably, rotating disk and steel loop, transition disc shell and clutch bell and controllable capacity pump and transition disc shell all fastening by binding bolt.Adopt this removable connection of binding bolt, under the prerequisite meeting sufficient intensity, be more convenient for the maintenance of all parts.
The utility model, owing to have employed above technical scheme, has significant technique effect:
Transition disc between connecting engine and controllable capacity pump is designed to the version of steel loop, rotating disk and spline housing combination by the utility model, avoid transition disc and controllable capacity pump castellated shaft forms a rigidity entirety, thus effectively reduce controllable capacity pump when High Rotation Speed, the situation that controllable capacity pump castellated shaft twists off or controllable capacity pump damages.
