  • Patent number: 9410598
    Abstract: A final drive assembly for a machine includes an input shaft drivably coupled to a prime mover. The input shaft is coupled to and drives a first stage gear assembly. The first stage gear assembly further drives a second stage gear assembly. The first and second stage gear assemblies drive a ring gear which is coupled to a wheel of the machine. The first and second stage gear assemblies are disposed between a first bearing assembly and a second bearing assembly. A spring member preloads the first bearing assembly to limit an axial movement of the first and second stage gear assemblies.

  • Publication number: 20140347032
    Abstract: A chip detector includes a plug configured to be coupled to a housing. The plug includes a first magnetic member and a second magnetic member spaced apart from each other so as to define a gap therebetween. Each of the first magnetic member and the second magnetic member is a rare earth magnet. A first electric contact is electrically coupled with the first magnetic member and a second electric contact is electrically coupled with the second magnetic member. A resistor is electrically coupled between the first electric contact and the second electric contact. An energy storage device is configured to provide a voltage difference between the first electric contact and the second electric contact. An indicating member is configured to provide an indication of a flow of current between the first and second electric contacts due to collection of chips in the gap between the first and second magnetic members.

  • Patent number: 8366578
    Abstract: A gear train assembly includes a first reduction planetary gear set having a rotating carrier and a second reduction planetary gear set having a non-rotating carrier. A plurality of vanes are attached to the carrier to direct oil from an oil bath towards the non-rotating carrier as the rotating carrier rotates.

  • Patent number: 8128524
    Abstract: A gear train assembly includes a planetary gear set partially submerged in an oil bath and having a plurality of planetary gears mounted on a rotatable carrier. A plurality of sheaths having a hydrodynamic profile are mounted on the carrier to reduce the churning and turbulence created by the planetary gears as they enter the oil bath.

  • Patent number: 5988335
    Abstract: A control system diverts cooling and/or lubricating fluid from a selected one of a plurality of fluid actuated clutches in a transmission in response to the transmission being in a selected gear ratio. A diverter valve is placed between a source of cooling and/or lubricating fluid and the selected one of the fluid actuated clutches and operative to divert fluid therefrom in response to the transmission being placed in the selected gear ratio. A sensor arrangement is operative to sense the transmission gear ratio and deliver a signal to condition the diverter valve.

  • Patent number: 5924951
    Abstract: A planetary transmission is disclosed including a front section having a first, a second, and a third planetary gear set each having a sun gear, a planet carrier and a ring gear. An input shaft is connected to at least two of the sun gears and the carrier of the third planetary gear set serves as the output. The front section of the transmission is operatively connected to a rear section for multi-speed use particularly adaptable to trucks or other machines.
