摘要:
A motor powered scooter for supporting a standing rider has an improved torsion acting shock absorbing mount for the cantilevered shock absorbing support of at least one of the scooter wheels from the frame. At least one torsion acting shock absorber is utilized. In a preferred embodiment, the torsion acting shock absorber includes a square sectioned metal tube, a correspondingly square sectioned metal shaft, and confined compressible rubber rods acting there between. The torsion acting shock absorber is attached at right angles to the main structural tube and protrudes at an end to one side of the main structural tube. A cantilevered wheel support is mounted offset from the main structural tube at the end of the shock absorber remote from the main structural tube. A shock absorbing suspension is disclosed for both the front steered wheel and the rear driven wheel.

An improved motor mount adjustably tensions the chain in a chain and sprocket driven vehicle. The vehicle has a frame, at least one driven wheel rotating from a wheel rotation point on the frame, a driven sprocket driving the driven wheel. A motor is mounted to the frame and has a driving sprocket at a motor sprocket rotation point on the motor. The driving sprocket is disposed in a plane including the driven sprocket, and powers a chain. An improved mount for mounting the motor from the frame relative to the driven sprocket includes a motor mount for fastening to the engine for disposing the driving sprocket from the engine overlying the driven sprocket powering the driven wheel. A motor mount pivot is provided on the motor mount for pivoting the driving sprocket along the plane including the chain and driven sprocket. A keeper slot is configured within the motor mount, the keeper slot being coaxial about the pivot to enable a keeper to slide relative to the keeper slot during pivot of the motor mount.

An integrated drive system assembly is provided that combines an electric motor, a power inverter assembly and a gearbox into a single, multi-piece enclosure. Combining these components into a single enclosure reduces weight, reduces drive system complexity, reduces system volume, simplifies assembly integration into an electric vehicle, reduces manufacturing cost, allows the flexible and lengthy electrical cables between the power inverter and the electric motor to be replaced with short, low loss, rigid bus bars, and simplifies component cooling by allowing the use of a common thermal management system, i.e., a mutual thermal management system. The common thermal management system includes a liquid coolant loop that is thermally coupled to the electric motor, the power inverter assembly and the gearbox.
