Abstract
The invention discloses a Z-shaped groove structure of a hydraulic torque converter and for containing welding slags. The Z-shaped groove structure comprises a pump impeller casing and a hydraulic torque converter casing connected with the pump impeller casing in a welding mode, a first step is machined on the outer side of the pump impeller casing, a second step is machined on the inner side of the hydraulic torque converter casing corresponding to the pump impeller casing, and when the pump impeller casing is welded to the hydraulic torque converter casing, the first step and the second step are combined to form a Z-shaped groove. Under the conditions that a stamping die is not changed and cost is not increased, a welding slag space is reserved for containing the welding slag effectively, the service life of an oil pump, the service life of a speed changer and the service life of the hydraulic torque converter are prolonged, machining and manufacturing are simple, raw materials and device cost are not increased, ATF cleanliness is guaranteed, and various faults caused by oil way blocking are reduced.
Description
Technical field
The present invention relates to a kind of automobile converter coupling, specifically the linkage structure of Pneumatic flat pushing valve pump impeller shell and fluid torque converter lid.
Background technique
The pump impeller shell of fluid torque converter and fluid torque converter lid are the difference punch process, during assembling, adopt welding technique that both are connected, unavoidably can produce welding slag during welding, in welding process, welding slag can enter in fluid torque converter by the narrow and small gap of pump impeller shell and fluid torque converter lid, accelerates the wearing and tearing of fluid torque converter and gearbox.
Summary of the invention
The objective of the invention is the deficiency existed for prior art, provide a kind of and reserve the fluid torque converter that the welding slag space effectively holds welding slag and hold Z-shaped groove structure for welding slag.
For achieving the above object, the technical solution used in the present invention is that a kind of fluid torque converter holds Z-shaped groove structure for welding slag, comprise the pump impeller shell with its torque converter housing welded mutually, the outside at the pump impeller shell is processed with first step, inboard at the torque converter housing corresponding with it is processed with second step, when pump impeller shell and torque converter housing welding, first step and second step are combined into the Z-type groove.
Described first step circle radius R5 is 51.477mm.
Described second step circle radius R3 is 51.477mm.
Converter coupling is mainly by cap assembly, the pump impeller assembly, the turbine assembly, lock-up clutch, guide wheel assembly five parts form, pump impeller shell in the fluid torque converter of the sealing of fluid torque converter in cap assembly lid and pump impeller assembly completes by welding, automatic transmission fluid (ATF) is arranged in fluid torque converter, play effect lubricated and that clean, ATF is at oil pump, in speed changer and fluid torque converter, circulate, must guarantee that it is clean, so in order to prevent entering of welding slag, the pump impeller shell of fluid torque converter and fluid torque converter lid respectively punching press complete after, step of inboard difference machining at the outside of pump impeller shell fluid torque converter lid corresponding thereto, when both carry out assembly connection by welding, can form a Z-shaped groove structure, there is certain free space.This Z-shaped groove structure can effectively be held the welding slag that when welding produces, and avoids welding slag to enter in fluid torque converter, affect the turbidity test of hydraulic transmission oil, generation high temperature and the harm such as easy to wear.
Beneficial effect: the present invention does not increase cost in the situation that do not change press tool, reserve the welding slag space and effectively hold welding slag, extend the working life of oil pump, speed changer and fluid torque converter, manufacturing is simple, do not increase raw material and equipment cost, guarantee the turbidity test of ATF, reduce because oil circuit stops up the various faults that cause.
The accompanying drawing explanation
Fig. 1 is torque converter housing structural representation of the present invention;
Fig. 2 is pump impeller shell structure schematic diagram of the present invention;
