Problems solved by technology

[0019] A problem inherent in the design of the original OEM shock absorber assemblies 100, 135 and 140 is that the shock absorber piston 102 overcomes the spring pressure on the steel shock absorber pins 106 and 147 For reciprocating motion, the energy storage shock absorber pin passes through the hole 102a located in the center of the piston, and the reciprocating motion causes wear on the pin / piston interface
This inherent mechanical wear problem results in clutch hydraulic leaks, poor shift quality, clutch and band damage

Embodiment Construction

[0038] Figure 5A A pinless energy storage shock absorber piston 10 consistent with the present invention is shown. It can be seen that the improved structure of the piston 10 of the current energy storage shock absorber eliminates the OEM pins 106, 147, hole 102a, and the corresponding pin / piston interface. This is precisely the hydraulic leakage of the clutch in the design of the OEM energy storage shock absorber. The main root cause. Because the pin 106 in the OEM forward clutch energy storage shock absorber 100 and the pin 147 in the 1-2 and 3-4 gear energy storage shock absorbers have been deleted in the current energy storage shock absorber assembly, so The central hole 102a in the OEM piston 102 is also omitted from the current piston structure, providing a radial solid web structure at 12b in the current design.

[0039] This design change of the present invention is accomplished by the energy storage shock absorber piston 10. The energy storage shock absorber piston 10 h...

Abstract

A clutch assemblage of energy storage damper comprises a piston fixed in the mating hole of the transmission case valve; a shell to posit the clutch assemblage into the transmission case valve. The web plate of the piston is of a radiating structure. A seal device is installed on the piston to seal the piston into the mating hole. A guiding device fixed on the piston to guide the movement of the piston. A spring with a bulk-head which is in the same position with the piston in the mating hole to reduce friction.

Description

Invention field [0001] This invention is mainly related to the field of automatic transmission systems. More specifically, it relates to the non-sale storage used in GM 4L60, 4T60, 4T60E, 4L60E and 4L80E gearboxes (hereinafter referred to as "GM gearboxes"). Clutch energy storage shock absorber assembly capable of shock absorber piston. Background of the invention [0002] The original design of the automatic transmission system has a hydraulic circuit subsystem, which includes at least one hydraulic pump, a valve body with a liquid conduction channel or circuit, input and output ports in the liquid circuit, and multiple The valve is composed of cylindrical pistons in the control ring. The pistons alternately open and close the liquid inlet and outlet in the valve body to adjust the flow and pressure of the automatic transmission oil (hereinafter referred to as "ATF") in the hydraulic circuit. [0003] Once released into a specific hydraulic circuit, the pressurized ATF acts to d...
