Bevel Gear Differential Patents (Class 475/230)
  • Patent number: 11092231
    Abstract: Disclosed herein is an axle assembly and a heavy load vehicle comprising the axel assembly. The axle assembly comprises an interaxle differential configured to distribute torque to first and second axles. The interaxle differential comprises an input shaft and an output shaft. A first gear wheel is journaled in a first bearing about the input shaft. The input shaft is journaled in relation to the output shaft via a tapered roller bearing having a small end and a large end. A lubricant receiving space is fluidly connected to the small end of the tapered roller bearing, and the large end of tapered roller bearing is fluidly connected to the first bearing. Thus, the first bearing is lubricated when there exists a difference in rotational speed between the input and output shafts.

    Abstract: A vehicle driveline component with a differential case, a cross-pin, a differential gearset, and a retaining member. The differential case is rotatable about a first axis and has an annular wall member that defines a differential cavity. The cross-pin is received in a cross-pin aperture formed through a first side of the annular wall member. The cross-pin extends through the differential cavity along a second axis that is perpendicular to the first axis. The differential gearset is received in the differential cavity and includes a pair of side gears, which are rotatable about the first axis, and a pair of pinion gears that are journally supported by the cross-pin and meshingly engaged with the side gears. The retaining member is welded to the annular wall member and limits movement of the cross-pin relative to the differential case along the second axis in a direction toward the retaining member.

  • Patent number: 9651132
    Abstract: A cast aluminum differential housing for a motor vehicle powertrain having cast iron inserts. The housing is cast of light weight aluminum which weighs approximately one-third that of iron which has formerly been used to fabricate such housings. At locations of significant loads and wear, such as the mountings for the stub shaft associated with the two idler bevel gears, iron inserts are cast into the housing. The housing thus weighs significantly less than a comparable iron differential housing but since the two significant wear and load bearing regions include cast iron inserts, the aluminum differential housing of the present invention has the ruggedness, durability and service life of the much heavier iron housing.

The wheels are supported by respective independent left and right suspensions allowing vertical travel of each wheel. The assembly features a differential module for splitting the torque two ways. The differential module is disposed between the left wheel and the right wheel and has a left side output and a right side output. The outputs spin at opposed directions. A left output axle couples with the left side output and extends to the left of the differential module. A right output axle couples with the right side output and extends to the right of the differential module. A left wheel axle is cross-coupled with the right output axle by a right inversion joint disposed at a distance to the right of the differential module. The left wheel axle extends toward and turns the left wheel.

  • Patent number: 9387756
    Abstract: A hybrid drive arrangement for a motor vehicle comprising two close-coupled electric traction motors/generators on the output of the vehicle differential. A constant velocity joint coupling device is incorporated into the central axis of the traction motors between the differential output shafts and the independent articulated axle shafts for the drive wheels. One embodiment comprises a kit for retrofitting an existing vehicle. The kit comprises two electric traction motors/generators incorporating the constant velocity joint coupling devices, two devices for mounting the traction motors to each side of the differential case between the differential and the independent, articulated axle shafts of the existing vehicle, a battery system electrically coupled to the traction motors, two traction motor controllers, and a vehicle sensing and control system. The arrangement provides for improved acceleration, deceleration, cornering, ease of parking, and fuel economy.

  • Patent number: 9261183
    Abstract: In a differential device, an outer tube portion is formed in one of a side gear and a sleeve, and an inner tube portion fitted to an inner periphery of the outer tube portion is formed in the other. A falling-off prevention device for preventing axial relative movement of the outer and inner tube portions is provided between the outer and inner tube portions. A seal member for shutting off communication between the falling-off prevention device and an inside of a differential case is set in a fitting portion between the outer and inner tube portions. Accordingly, lubricating oil in the differential case is prevented from leaking out of a space between the side gear and the sleeve without performing a special process such as pressure welding or adhesive bonding during assembly and which has good ease of assembly.
