Patent number: 8561735Abstract: A self-contained axle module for a vehicle having a support structure is provided. The self-contained axle includes a housing removably coupled to the support structure and an output shaft extending from the housing. An electric motor is coupled to the housing and drives the output shaft. Two wheel end assemblies are coupled to the output shaft, and an independent suspension assembly is coupled between each wheel end assembly and the housing, so that the independent suspension assemblies and the wheel end assemblies and the electric motor and the housing are removable from the vehicle as a unit by detaching the housing from the support structure.Type: GrantFiled: October 8, 2009Date of Patent: October 22, 2013Assignee: Oshkosh CorporationInventors: Jon J. Morrow, Eric Braun, Nader Nasr, Gary Schmiedel, Martin Schimke, Donald H. Verhoff, Christopher K. Yakes

Patent number: 7357203Abstract: A self-contained axle module for a vehicle. The vehicle includes a support structure, a source for electric power, a source of cooling medium, and a vehicle control device. The self-contained axle includes a first side plate removably coupled to the support structure. A second side plate removably coupled to the support structure. A housing coupled to the first and second side plate. An electric motor coupled to the housing and the source for electric power. A motor drive controller unit coupled to the electric motor and to the vehicle control device to communicate signals to the vehicle control device such that one of the speed and torque of the electric motor is controlled based upon the signals. A gear train is mounted in the housing and coupled to the electric motor and an output shaft, wherein, the self-contained axle module can be selectively coupled and decoupled from the support structure.Type: GrantFiled: September 28, 2004Date of Patent: April 15, 2008Assignee: Oshkosh Truck CorporationInventors: Jon J.

Patent number: 5820150Abstract: A modular independent coil spring suspension for steerable and non-steerable wheel assemblies and driven and non-driven axles. The suspension is of the general type in which each wheel has an upper and a lower control arm, and a single coil spring secured between the lower of the two control arms and the chassis. The upper and lower control arms each have inner ends split into two segments, each of which is connected to the vehicle frame by a special bushing assembly. The suspension has a novel upper control arm which is split into two segments, each segment being bent to accommodate an edge of the frame of the vehicle, thereby allowing the frame of the vehicle to be mounted lower with respect to the wheel assemblies.Type: GrantFiled: July 22, 1996Date of Patent: October 13, 1998Assignee: Oshkosh Truck CorporationInventors: David W. Archer, Brian K. Anderson, Eric E. Braun, James L. Steiner, Donald H. Verhoff

Patent number: 5217083Abstract: An all wheel steering system for heavy vehicles such as airport and municipal service vehicles. A rear wheel lockout is provided to ensure safe operation by preventing rear steering above a pre-set vehicle speed. The system can be adjusted so that rear steering range angles can be varied to fit particular applications. The steering control involves the use of a closed loop position feedback circuit in which a change in the relative polarity of the command and feedback RVITs results in switching of the system between various modes.Type: GrantFiled: May 11, 1992Date of Patent: June 8, 1993Assignee: Oshkosh Truck CorporationInventors: Anthony A. Bachhuber, Donald H. Verhoff

Patent number: 5209003Abstract: An auger type snow blower assembly having an auger with two sets of rotating ribbon spokes which transfer snow from the auger to an impeller inlet located at the mid-portion of the auger assembly, the ribbon spokes terminating a substantial distance short of the center of the auger assembly whereby snow lying directly in the center of the path of the auger assembly may move directly to the impeller inlet without contact with the ribbons. Further, the ribbons revolve around a generally cone-shaped structure at the ends of the auger assembly whereby the ribbons and the stationary cones cooperate to impel snow entering the auger assembly toward the impeller inlet. The auger assembly further includes a bi-directional, variable speed hydraulic drive system for the ribbon system consisting of variable forward speeds and reverse speeds, the forward speeds including a low ribbon speed high torque speed, and a high ribbon speed low torque speed, together with pressure relief valves to avoid the use of shear pins.Type: GrantFiled: November 4, 1991Date of Patent: May 11, 1993Assignee: Oshkosh Truck CorporationInventors: LeRoy Maxfield, Donald H. Verhoff, David R. Church

Patent number: 5111901Abstract: An all wheel steering system for heavy vehicles such as airport and municipal service vehicles. The system includes several display devices to inform the operator of the operational status of various components of the system. A rear wheel lock-out is provided to ensure safe operation by preventing rear steering above a pre-set vehicle speed. The system can be adjusted so that rear steering response timing and front and rear steering range angles can be varied to fit particular applications.Type: GrantFiled: February 27, 1991Date of Patent: May 12, 1992Assignee: Oshkosh Truck CompanyInventors: Anthony A. Bachhuber, Donald H. Verhoff
