Patent number: 11964535Abstract: An electric automotive vehicle gross vehicle rating of greater than 10,000 pounds includes an electric powertrain connected to the frame and positioned at a base of the frame. The vehicle includes a first central axis, and the weight of the electric powertrain is centered about the first central axis. All drivetrain components of the vehicle other than the electric powertrain may be positioned above the base of the electric powertrain. The vehicle includes two electric drive units configured to drive the front and rear axles respectively. The electric drive units consist of an electric motor, motor controller, two speed electrically actuated gearbox, electrically actuated park lock, and electrically actuated locking differential. The drive units transmit power to inboard mounted brakes, which in turn are connected by constant velocity driveshaft to the wheel hubs where a further final gear reduction resides.Type: GrantFiled: October 12, 2020Date of Patent: April 23, 2024Assignee: BOLLINGER MOTORS, INC.Inventors: Robert Bollinger, Brian Van Batavia, Karl Hacken, Erik Hardy, John Dannenhoffer, Charles Winegar

Patent number: 4882859Abstract: The invention relates to an excavating bucket including two scoops (13) mounted movably, with respect to a frame (1), from an open terrain-engaging position to a closed position in which they enclose a certain quantity of cuttings. It comprises a central bucket body (5), integral with said frame and including at least two lateral walls (6), the scoops being arranged so that, in closed position, they come toward the central body from both directions with their lateral walls extending from the lateral walls of the central body.Type: GrantFiled: October 25, 1988Date of Patent: November 28, 1989Assignee: SoletancheInventor: Karl Bollinger

Patent number: 4883134Abstract: The invention relates to a motor-driven milling machine construction for cutting trenches in the ground, in which there are two rotating semi-drums with cutting tools at their periphery. The drums are mounted on a central support. The sole function of the motor is to transmit a rotational torque to the semi-drums without transmitting any other forces. The stress exerted on the cutting tools is directly transmitted to the central support without going through the motor frame.Type: GrantFiled: September 25, 1987Date of Patent: November 28, 1989Assignee: SoletancheInventors: Karl Bollinger, Daniel Barre
