US Patent:

7014426, Mar 21, 2006

Filed:

Feb 14, 2003

Appl. No.:

10/367202

Inventors:

John C. Schultz - Saline MI, US

Assignee:

General Motors Corporation - Detroit MI

International Classification:

B63H 1/16

US Classification:

416180, 416181, 60330, 298895

Abstract:

The invention provides a high-strength stamped aluminum brazed turbine for use in an automotive transmission torque converter, and a method therefor. The method includes stamping aluminum inner and outer shells each having a plurality of slots, and stamping a plurality of aluminum turbine blades having tabs. The tabs of the turbine blades are inserted into the slots of the inner and outer shell, and the tabs are bent to attach the turbine blades to the inner and outer shell. The turbine blades are brazed to the inner and outer shell with a silicon material, thereby forming a turbine of sufficient strength to operate in the powerflow path of an automotive transmission using transmission oil as its working fluid.

International Classification:

F04B 23/04
F04B 23/08
F04B 23/00

US Classification:

417 79, 417 87, 417307, 417313, 210307, 210440

Abstract:

The filter housing has a filter outlet portion with a central filter outlet passage. The outlet portion includes a terminal end portion defining a filter nozzle. The filter nozzle forms a nozzle passage between the filter nozzle and the pump housing. The nozzle passage communicates with an annular recess formed in the filter outlet portion. The annular recess receives return bypassed hydraulic fluid from a regulator valve for distribution into an inlet stream of fluid flowing through the filter outlet passage. The inlet stream velocity is increased which increases the pressure at the pump inlet. The increased pressure at the pump inlet allows the pump to operate at higher speeds without cavitation.

US Classification:

210232, 2103231, 21016708, 2104165

Abstract:

A method and apparatus for a compact dual transmission filter design is provided. More precisely, a single filter housing is adapted to accommodate a primary filter and an auxiliary filter in fluid communication with a primary pump and auxiliary pump, respectively. The single filter housing having two filters disposed therein is more compact than a conventional design incorporating a separate filter housing for each filter.

Abstract:

A system for maximal gathering of fresh information added to a network such as the as the Internet and for processing the gathered fresh information. A link server () sends a batch of links to check () to a crawler (B). Crawler (B) them executes its crawling assignment by filtering the encountered content and extracting only that which is new or changed (). Crawler (B) then returns this content () to at least one data center and any interested web mining application (). By using the crawlers (A-E) to filter the data and only return or notify regarding, the fresh content, less bandwidth is needed to get the information to the web mining application ().

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F04B 23/00

US Classification:

417313, 4174239

Abstract:

A filter and pump include complementary engagement features such that the filter is inserted into the pump and thereafter rotated approximately 90 degrees to engage a twistlock feature. In this manner, filter attachment is maintained without additional fasteners, spring clips, clamping plates, etc.

Inventors:

John C. Schultz - Saline MI, US

Assignee:

GM Global Technology Operations, Inc. - Detroit MI

International Classification:

F16H 45/02

US Classification:

192 327, 192 8714, 192212, 192107 M

Abstract:

A dual clutch engine coupling damper includes a slipping ECCC clutch in series with a plurality of damper springs, and a bypass clutch in parallel with the damper springs. The ECCC is adapted for use when the vehicle engine is running and the bypass clutch is adapted for use when the vehicle engine is being started. The dual clutch engine coupling damper incorporates a single pressure plate design adapted to actuate both the ECCC clutch and the bypass clutch. The single pressure plate design is compact and minimizes axial space requirements for the apparatus. Additionally, the components of the present invention are primarily stamped parts which may be produced in an inexpensive and efficient manner.

Inventors:

John C. Schultz - Saline MI, US

Assignee:

GM Global Technology Operations, Inc. - Detroit MI

International Classification:

F16D 33/00

US Classification:

192 327

Abstract:

A dual-input clutch transmission is provided having a torque converter with a rotatable hub, the transmission comprising a transmission pump having internal fluid channels and a rotor set which is drivingly connected to the hub, and a dual-input clutch in fluid communication with the transmission pump through the fluid channels. The pump and torque converter are positioned along a common axis of rotation, the pump circumscribing the torque converter hub to reduce axial space. The dual-input clutch is mounted to the transmission pump housing for structural support. A method is also provided for reducing axial space within a dual-input clutch transmission having a torque converter, including providing an on-axis transmission pump with a housing and rotor set, providing a torque converter with a rotatable hub which is drivingly connected to the rotor set for powering of the transmission pump, and mounting the dual-input clutch to the pump housing for support.

International Classification:

US Classification:

417151, 417 79, 417313, 210437, 210440, 210307

Abstract:

A hydraulic system for a transmission has a diffuser housing with a fluid inlet passage that feeds one or more pump inlet ports, and a fluid return passage, such as to return fluid from a pressure regulator valve, that is in fluid communication with the fluid inlet passage. The hydraulic system also has a filter housing with a filter outlet portion that is in fluid communication with the fluid inlet passage upstream of the pump inlet port(s). The fluid return passage is downstream of the filter outlet portion. Thus, flow through the fluid return passage can create suction, causing increased flow through the filter outlet portion, such as from a fluid sump. Specifically, the diffuser housing is configured so that the fluid inlet passage has a converging portion downstream of the filter outlet portion and a diverging portion downstream of the converging portion.
