Abstract

A lubricating system for change-speed transmissions, especially of vehicles with spray nozzles connected with a pressure line system for the gears supported in the transmission housing and the bearing places thereof, whereby one or several pipe lines are used that are installed freely along the pairs of gears between cross walls of the transmission housing and nozzle-like discharge apertures are provided in the pipe lines for each of the gear pairs which are directed against the tooth area in front of the point of tooth engagement.

Claims

1. A lubricating installation for change-speed transmissions, especially for transmissions of vehicles having spray nozzle means connected with a pressure line system for lubricating a plurality of gear pairs supported between cross-wall means of a transmission housing, characterized in that the lubricating installation includes pipe-line means placed freely along the gear pairs between the cross-wall means of the transmission housing, in that the pipe line means are provided with nozzlelike discharge aperture means for each of the gear pairs, said discharge aperture means being directed against the tooth area of respective gears in front of the point of meshing engagement of the teeth thereof, and in that the pipe-line means is supported exclusively at parts consisting of the cross-wall means of the transmission housing and a cover of the transmission housing and is provided with several discharge aperture means in the plane of each of the gear pairs arranged adjacent one another of the change-speed transmission, of which one aperture means is directed against a driving gear and the other aperture means is directed against the driven gear of the respective gear pair.

2. A lubricating installation according to claim 1, characterized in that the pipe line means extends in the gap between the driving and driven gear and is retained at an approximately constant distance relative to the associated point of tooth engagement of each of the gear pairs.

3. A lubricating installation for a change-speed transmission combined with a differential gear which includes a bevel gearing means according to claim 2, characterized in that the discharge aperture means are directed transversely to the pipe plane against the gear pairs of the change-speed transmission and against the bevel gearing means of the differential gear.

4. A lubricating installation according to claim 3, characterized in that the pipe line means is retained in bores of bearing webs of the transmission housing by means of elastic intermediate rings.

5. A lubricating installation according to claim 4, characterized in that one end of the pipe line means is provided with a plug-type connecting means.

6. A lubricating installation according to claim 1, characterized in that one end of the pipe line means is provided with a plug-type connecting means.
