A dual-independent powertrain for a vehicle includes a transmission enclosure that houses a first transmission and a second transmission that are mechanically decoupled from each other. The enclosure includes a central frame, a first enclosure cover that interfaces with the central frame to collectively define a first transmission region on a first side of the central frame, and a second enclosure cover that interfaces with the central frame to collectively define a second transmission region on a second side of the central frame. The first transmission is housed within the first transmission region, and the second transmission is house within the second transmission region. Each transmission includes a motor-interfacing shaft that interfaces with a respective electric motor, a drive-interfacing shaft that interfaces with a respective drive wheel of a vehicle, and a multi-stage gear train mechanically coupling the motor-interfacing shaft and the drive-interfacing shaft.

A three wheeled vehicle is disclosed having a radiator positioned forward of an engine and coupled to the engine for cooling the engine. A front radiator shroud is positioned over the radiator on a front side and a rear radiator shroud is positioned over the radiator on a rear side. The rear radiator shroud has a rear baffle plate directing air downwardly and under the operator's compartment.

A vehicle tilting system is used for a tricycle. The tricycle has a front body and a rear body. The front body has a front wheel. The rear body has two rear wheels. The vehicle tilting system has a track assembly and a sliding base assembly. The track assembly is arcuate in shape. The sliding base assembly slides on the track assembly.

Disclosed is a caddy system for personal vehicle. As a two or three-wheeled vehicle. The term personal vehicle as used herein is intended as a broad classification for two and three wheeled motorcycles. It further includes three and four wheeled all-terrain (ATV) vehicles. In broad terms, the caddy includes a platform that is supported by a series of wheels. The caddy is designed to be tipped forwardly or rearwardly as needed to allow the vehicle to enter onto and exit off the platform. Once upon the caddy, a single user can easily move, maneuver, or manipulate the vehicle. This is ideal for storing and/or maintaining the vehicle.

An apparatus includes a vehicle frame, a swing arm and a fuel tank. The vehicle frame includes a front portion and a rear portion and defines a longitudinal centerline therebetween. The front portion is configured to support a recumbent seat. The rear portion is configured to be coupled to the swing arm and. The swing arm defines a longitudinal centerline and includes a wheel mounting portion configured to be coupled to a wheel assembly. The wheel mounting portion defines a radial axis that is substantially coaxial with the longitudinal centerline of the vehicle frame in at least one plane. The fuel tank is coupled to the rear portion of the vehicle frame such that the fuel tank is above the longitudinal centerline of the swing arm.

Provided is a method for fastening a separation type tricycle in which a connecting pipe for connecting a front wheel part and a rear wheel part can be separated from and fastened to a head tube of the front wheel part, wherein the front wheel part and the rear wheel part are separated from each other by forming an ear-shaped groove, in which a handle bar can be put, in a right-side-open rectangular shaped plate fixed to the end of the connecting pipe so as to be used for attachment/detachment in a fastening device of the head tube, and then the end of a connecting bar for connecting the front wheel part and the rear wheel part is put on the handle bar by using the groove and another place is fixed thereto so as to set three wheels at the shortest distance therewith, thereby conveniently moving and storing the tricycle.

A saddle riding type vehicle includes left and right front wheels that unlock linkage more surely when the vehicle starts. The vehicle includes a linkage that connects the left and right front wheels to a vehicle body frame, a lock that locks or unlocks the linkage, a lock controller that controls the lock, a wheel speed sensor that detects a vehicle speed, and a vehicle speed change rate obtainer that obtains a vehicle speed change rate. The lock controller unlocks the linkage via the lock if the linkage is locked by the lock and at least one of the vehicle speed and the vehicle speed change rate satisfies an unlocking condition.

A saddle type vehicle which can cool a battery efficiently by a simple configuration. The saddle type vehicle includes a battery case accommodating a battery therein and is provided in a space positioned above an engine, which configures part of a power unit, below a seat (occupants' seat) and overlapping with the engine and the seat in an upward and downward direction of a vehicle body. A cooling fan configured to discharge air rearwardly is provided at a rear end of the battery case.

A human-propellable vehicle (1) is described which comprises a chassis (2), and a rear wheel assembly (5) mounted to a rear portion of the chassis. The rear wheel assembly comprises a double wishbone suspension assembly, each wishbone (14, 22) of the double wishbone suspension assembly being coupled to the chassis at first and second coupling points, the second coupling point for each wishbone being closer to the rear of the chassis, and closer to the longitudinal axis of the vehicle, than the first coupling point for that wishbone. By using a double wishbone set up at the rear of the bike it is possible to control weight transfer more efficiently. By providing a second coupling point for each wishbone which is closer to the rear of the chassis, and closer to the longitudinal axis of the vehicle, than the first coupling point for that wishbone, it is possible to utilise a setup without having to adopt a higher seating position and without having to increase the rear wheel track beyond an acceptable width.

The general layout for a front wheel drive, three-wheeled vehicle designed for road use with two steerable driven wheels in the front of the vehicle, and the engine located behind the front of the passenger seating. The vehicle layout is designed for optimal stability and traction by the location of the passenger seating, engine or engines, steering and driven wheels.
