Abstract:
A straddle electric vehicle (1) comprises a battery case (23) accommodating a battery (22) which is an electric power supply for an electric motor (5); and an air box (51) attached to an upper portion of the battery case (23), and the air box (51) includes a ram air inlet (61b) through which ram air flows into the air box, and a ram air supply port (54a) through which the air is supplied from inside the air box to the battery case (23).
Abstract:
Various personal mobility vehicles, such as scooters, are disclosed. The scooter can include at least one battery and motor for powering at least one driven wheel. The vehicle can include a gear assembly to convert a torque produced by the motor to a different torque to a driven shaft to power the at least one driven wheel. The battery can be removable.
Abstract:
A folding personal mobility vehicle includes a foothold part (100) provided with a wheel (10), a handle part (200) provided with a handle (20), and a hinge structure (40) between the foothold part (100) and the handle part (200). The foothold part (100) and the handle part (200) are each configured to be folded using the hinge structure (40) and the foothold part (100) and the handle part (200) are configured so that the foothold part (100) is positioned between the handle parts (200) in a folded state.
Abstract:
The problem addressed by the invention is that of specifying an efficient control strategy for an electric motor scooter. This problem is solved by means of a motor scooter having the following features: at least one electrical drive (40); at least one electrical battery (60); at least one operating unit, in particular one thumb lever (31), wherein the operating unit is designed in such a way that the operating unit can be brought into different positions along a total operation distance (sGes); a controller, which is designed to sense the position (P) of the operating unit, to select a driving mode from a set of driving modes in accordance with the sensed position, and to set the selected driving mode, wherein the driving modes comprise: g) recuperation mode; h) coasting mode; i) acceleration mode, wherein, when the recuperation mode is set, the controller (300) controls the electrical drive in such a way that energy produced in the electrical drive (40) is output at least partially to the battery (60).
Abstract:
A driving force control system according to the present invention is for use in a vehicle which transmits motive power of a driving source to a driving wheel via a centrifugal clutch. The centrifugal clutch includes an upstream component mechanically connected to the driving source to rotate and a downstream component to be mechanically connected with or disengaged from the upstream component based on a centrifugal force which is in accordance with rotation of the upstream component. Transmission of motive power between an upstream-of-centrifugal-clutch path from the driving source to the upstream component and a downstream-of-centrifugal-clutch path from the downstream component to the driving wheel is automatically turned ON or OFF with a centrifugal force which is in accordance with rotation of the upstream component of the centrifugal clutch. The driving force control system controls the driving force of the driving wheel in the downstream-of-centrifugal-clutch path in accordance with a physical parameter concerning rotation of the upstream-of-centrifugal-clutch path, at least when the centrifugal clutch is in a half-clutch state.

Abstract:
Disclosed is a radiator cooling structure for cooling a radiator 67 of a water-cooled power unit mounted on a small vehicle and disposed on a laterally outer side of the small vehicle, which radiator cooling structure improves the efficiency of cooling an internal combustion engine 16 by using a head wind. The radiator 67 is provided with a radiator cover 68 having a louver 69 for guiding cooling air to the radiator 67. The louver 69 is formed such that a rear part thereof is more protruded laterally outward than a front part thereof. The louver 69 of the radiator cover 68 has parallel slats 69a tilting forward, and a lower body cover 13A is provided with a cooling air intake opening 70 capable of guiding a head wind toward the louver 69 positioned obliquely above and rearward of the cooling air intake opening 70.
