  • Patent number: 7073406
    Abstract: A cable or another longilinear transmission component is set into the center of an axial cavity of a screw belonging to a screw and nut movement conversion unit. By means of this arrangement, bending moments exerted on the screw between the point of attachment of the component and the nut have only a small value, which guarantees the screw against bending and sticking and the whole mechanism against excessive friction.

  • Patent number: 7069807
    Abstract: A vehicle transmission detent assembly is provided that includes a housing having a bore. A movable shift rail is supported by the housing and includes a recess at least partially aligned with the bore. A detent is at least partially arranged within the bore and engages the recess. A biasing member generates a force on the detent and urges the detent into engagement with the recess. An adjustment member threadingly received within a portion of the housing coacts with the biasing member. Upon manipulation of the adjustment member, the biasing member may be moved between a plurality of compressive states in which each of the states generates a different force on the detent. In this manner, the biasing spring may be compressed or uncompressed to provide a desired shift feel.

  • Patent number: 7040453
    Abstract: A lubricant retention assembly is employed with an electric motor to prevent the loss of lubricant from a self contained lubricant reservoir of the motor. The lubricant retention assembly includes a thrust collar mounted on the motor shaft and a bearing cap surrounding the thrust collar, where the thrust collar has an annular flange that throws lubricant leaking along the shaft radially outwardly toward the bearing cap. The bearing cap has an angled interior surface that deflects the lubricant thrown from the annular flange of the thrust collar back into the motor interior and toward the lubricant reservoir. A thrust washer is also provided on the shaft adjacent the thrust collar and prevents lubricant leakage along the shaft between the interface of the shaft and the thrust collar. The thrust washer and thrust collar have complementary configurations that maintain the thrust washer in position on the shaft adjacent the thrust collar.

  • Patent number: 7040454
    Abstract: The interior of a crankcase is divided into a front crank chamber and a rear transmission chamber by a partition wall of a given height. A lower part of the transmission case is used as an oil reservoir chamber for reserving lubricating oil. Opposite ends of the crankcase are covered with covers to form a generator chamber and a clutch chamber. The crank chamber is connected to the generator chamber by a drain passage to drain oil collected in the crank chamber into the generator chamber. A scavenging pump placed in the clutch chamber sucks the oil collected in the generator chamber through an oil passage extending across the crankcase under the crank chamber and discharges the oil into an air space in the clutch chamber.

  • Patent number: 7036393
    Abstract: A gear 1 made of a resin includes webs 5 (5a and 5b) formed so that the rigidity of the web is increased by a first circumferential rib 8, a second circumferential rib 10, first diametrical ribs 11 and second diametrical ribs 12, and the circumferential sectional shape of the outermost web 5c is a corrugated shape, whereby the rigidity of the outermost web 5c is increased. As a result, it is possible to increase the rigidity of the outermost web 5c without increasing of the thickness of the outermost web 5c; to form a toothed portion 6 with a high accuracy; to reduce the deformation (for example, the amount of displacement of the toothed portion 6 and a shaft-supporting portion 4 in a rotating direction) due to an external force; and to enhance the rotation-transmitting accuracy. In this gear 1, a vibration and a noise due to the vibration can be reduced by increasing the rigidity of the web.

  • Patent number: 7036634
    Abstract: A vehicle transmission lubrication communication system including a pump, a torque converter, an oil cooler, a shifting control assembly, a sump, a main shaft, a counter shaft, and a secondary shaft. The pump withdraws lubricating oil from the sump and pumps the lubricating oil throughout the lubrication system. The pump directs a first flow to the torque converter, a second flow to the shifting control assembly, and a third flow to the main shaft. Oil from the torque converter flows through the oil cooler and, downstream the oil cooler, separates into a first portion of cooled oil that is directed to the secondary and counter shafts and a second portion of the cooled oil that is directed to the sump. Increased flow through the torque converter and oil cooler, as well as directing cooled oil to the secondary and counter shafts, reduces the oil temperature during normal and lockup modes of operation.
