An oil reservoir for a vehicle transmission includes a separately formed oil pan and suction tube each formed of plastics material. A filter cartridge is disposed about a lower end portion of the suction tube to filter oil entering an oil inlet of the suction tube at the lower end. The suction tube and floor of the oil pan have snap-together connecting structure. To assemble the suction tube with the floor of the oil pan, the tube is simply pressed toward the pan causing the connecting structure to engage with a snap-fit connection.

Snap-together filter system for transmission oil pan and method of manufacture

An oil reservoir for vehicle transmissions includes an oil pan, cover, and filter cartridge which are manufactured as separate components. The cover is attached to the pan preferably with a snap-fit connection. The filter cartridge is releasably secured in position between the cover and pan so as to enable the module to be installed and removed without having to disconnect the cover from the pan

A shaft seal assembly includes an outer stationary carrier, an inner member, and a sealing system including a primary lubricant-retention seal that is fixed to the carrier in combination with a number of debris-excluding seal features. Such features include a first debris-exclusion seal fixed to the carrier adjacent the primary seal and a second debris-exclusion seal that is mounted on either the carrier or inner member and has at least one lip sealingly engaging the other of the carrier and inner member in spaced relation to the first debris-exclusion lip defining a sealed annular cavity therebetween. Disposed within the cavity is a porous filter element in the preferred form of an open cell sponge. The various dust exclusion features cooperate to allow each to perform efficiently. The outermost second debris-exclusion seal guards the foam against substantial debris, and the foam in turn protects the first debris-exclusion lip against virtually all debris. That which escapes the filter is prevented by the first seal member from contacting the primary oil-retention lip.
