Mid-engine three wheel vehicle

Abstract

The general layout for a front wheel drive, three-wheeled vehicle with two steerable driven wheels in the front of the vehicle, and the motor or motors located in the mid-section of the vehicle. The vehicle is designed for compact motors, in-hub motors, and direct connect motors which allow a significant portion of the vehicle's weight to be moved forward, while integrating location of the passenger seating, steering, and driven wheels allows for a highly stable vehicle. The layout maintains the traditional bucket or bench style seats as found in today's automobiles, and yet allows for weighting and cockpit adaptability for different market demographics.

Claims

1. A three wheel vehicle comprising: two driven front wheels which allow primary directional control of the vehicle; a single non-driven rear wheel; a passenger compartment, the compartment comprising one or more traditional passenger seats; a mid-section, comprising the area of the passenger compartment forward of the front of the seat; a motor or motors to propel the vehicle either directly or indirectly through the front wheels, located in a position which transversely overlaps the mid-section.

(13) Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the detailed arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments not listed herein, and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.

DETAILED DESCRIPTION OF THE INVENTION

(14) FIG. 5 portrays the general layout of the components of the present invention within the embodiment of a two passenger, serial seating arrangement with one motor. Regardless of the number or type of motors, and number or arrangement of seats, there are key components which define the present invention. The key components are two driven and steerable front wheels (item A), a rear wheel (item D) which is located behind the front wheels, a passenger compartment (item E) with conventional seats for one or more passengers, one or more passenger seats (item B), and one or more motors (item C) overlapping the midsection of the vehicle.

(15) The mid-section of the vehicle (item G) is the area of the vehicle extending from the front of the seat to the front of the passenger compartment to along the X-axis. The X axis is the centerline of the vehicle extending from the front to the rear. If there are multiple seats, then mid-section is defined by the front of the forward most seat.

(16) The motor is in a location that overlaps or partially overlaps the mid-section of the vehicle along the X axis. This does not imply that the motor must be in or part of the passenger compartment. The motor may be within or external to the passenger compartment itself. The overlap along the X axis may be full or partial. A full overlap is when the entire motor is within the mid-section plane of the vehicle. A partial overlap is when any portion of the motor overlaps the mid-section plane. Regardless of the amount of overlap, any overlap with the mid-section of the vehicle defines the vehicle as mid-engine and is within the context of the present invention. This overlap articulates the mid-engine design of the present invention.

(17) As with the numerous embodiments of existing three wheeled vehicles, the present invention also has numerous possible embodiments. FIG. 1, 2, 3, 4 depict example embodiments of the present invention.

(18) FIG. 1 and FIG. 2 show an example embodiment of the present invention with dual passenger side by side seating and a single motor. The key components are two driven and steerable front wheels (item A), a rear wheel (item D) which is located behind the front wheels, a passenger compartment (item E) with conventional seats for one or more passengers, one or more passenger seats (item B), and a motors (item C) overlapping the midsection of the vehicle.

(19) FIG. 3 and FIG. 4 show an embodiment with single passenger seating and dual motors. The key components are two driven and steerable front wheels (item A), a rear wheel (item D) which is located behind the front wheels, a passenger compartment (item E) with a conventional seat for one passengers, one passenger seat (item B), and two motors (item C) overlapping the midsection of the vehicle. An exemplary embodiment would use in-hub electric motors directly attached to the wheels, or electric motors attached via a shaft.

(20) FIG. 5 depicts the motor location with respect to vehicle section, whether Front, Mid, Rear section. The example embodiment is the present invention with dual passenger serial seating and dual motors, and shows the mid-section of the vehicle. To help contrast the present invention from previous art, FIG. 6 and FIG. 7 are provided. FIG. 6 depicts existing art with the motor located in the front section of the vehicle, which is typically known as a front engine vehicle. FIG. 7 depicts existing art with the motor located in the rear section of the vehicle, which is typically known as a rear engine three wheel vehicle.

(21) The present invention may utilize a variety of motor to driven wheel connection types (item F) and is not limited by possible types. Example connection types may include chain, belt, hydraulic, shaft, or direct. The method used to connect the motor to the wheels is not critical to the intent of the present invention. In certain embodiments, such as an in-hub motor, there may not be any additional connections required between motor and wheel.

(22) The present invention is not limited by motor type or number of motors. Gasoline, Hydrogen, Steam, Electric and other motor type embodiments are not limiting factors of the present invention. The terms motor and engine are used interchangeably and are not viewed as limiting terms within the present invention.

(23) If seating is adjustable, references to ‘front of seat’ indicate the forward most position of the seat. If multiple seats are used, the ‘front of seat’ refers to the seat in the forward most position in the vehicle.

(24) The present invention is limited to standard sit-in or sit-on type passenger seats (Item B), which is also referred to as ‘traditional’ seating. The present invention does not extend to vehicles with straddle seating, in which the passenger has one leg or foot on either side of the motor or primary body of the vehicle, regardless of whether the passenger is in a forward leaning, vertical, rearward leaning, reclined, or horizontal position. Straddle type seating may have the motor directly underneath, forward, or rearward of the driver.

(25) In addition to items noted above, the present invention is not limited by: frame or body structure type or material. distances between items. classification of vehicle such as motorcycle or car. construction details. suspension types and variations. body types. other vehicle components.

(26) While this invention has been described with several embodiments, the present invention may be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains.
