Abstract
The utility model discloses an automatic transmission flywheel of an integrated engine. The automatic transmission flywheel comprises a signal tray, wherein the rim of the signal tray is provided with signal teeth along the periphery; a tooth gap is arranged among the signal teeth; the signal tray comprises a groove arranged in the middle and a signal tray plane; a step is arranged between the bottom plate of the groove and the signal tray plane; the bottom plate of the groove is provided with a central hole; the bottom plate of the groove around the central hole is provided with a crank bolt connecting hole along the periphery; the bottom plate of the groove is also provided with a positioning pin hole; and the signal tray plane is provided with a locking hole and a torque converter connecting hole. In the utility model, the original component connecting structure of two different production processes is turned into flywheel components of an integrated stamping process. Therefore, the weight is light, the structure is simplified and the connecting assembly structure is simplified.
Description
Technical field
The utility model belongs to engine component, is specifically related to a kind of motor automatic catch flywheel.
Background technique
Automatic catch flywheel originally is made up of pallet and a triangle dish of a band gear ring, and the triangle dish adopts the 2mm Plate Steel to be stamped to form.The former technology of flywheel ring gear pallet is to adopt the thick 45# steel plate of 10mm to become blank by 800t numerical control precise forging machine finish forge, shapes by machining then, and the thinnest to be worked into 3.5mm thick.Also need to mill out three delthyriums to remove weight.This technology cutter consumption is big, and stock utilization is low, and productive temp is slow.
Summary of the invention
The purpose of this utility model is to provide a kind of integral engine automatic catch flywheel, to address the above problem.
The technical solution of the utility model is: integral engine automatic catch flywheel, it comprises the signal pallet, the signal tray edge is established signal teeth along circumference, being provided with a tooth between signal teeth lacks, the signal pallet comprises groove and the signal holding tray surface that establish at the middle part, be provided with step between groove base plate and the signal holding tray surface, offer center hole on the groove base plate, groove base plate around the center hole offers the crank shaft bolt attachment hole along circumference, also offer positioning pin hole on the groove base plate, offer locking hole and torque-converters attachment hole on the signal holding tray surface.
The utility model changes the structure of the part connection of two original various processes into the flywheel part of whole stamping process, former design pallet blank gross weight 5.5kg, material only has 2.5kg after the completion of processing, whole stock utilization only is 46%, the heavily about 2kg of the integrated material pallet blank of the utility model, finished product is about 1.4kg, and stock utilization is 70%.New designing material use amount is original 36%.And saved a triangular plate; Simplified structure is simplified the structure that is linked and packed.
