Saddle-type vehicle having hybrid propulsion device

Abstract

The invention relates to a saddled vehicle, which is a motorcycle or a light motorcycle, comprising a frame (2), at least one steering wheel (3) rotatably connected to the frame, and a single drive wheel (4). The vehicle further comprises a motor assembly (10) and a transmission unit (T) mechanically connecting the motor assembly (10) to the drive wheels. The motor assembly comprises a heat engine (MT) with a crankshaft (11), an electric machine (E) with a stator (S) and a rotor (R), and a clutch (C) with a drive shaft (C1) and a driven shaft (C2). The motor assembly (10) further comprises a gearbox (G) provided with an input shaft (111) and an output shaft (112). According to the invention, the crankshaft (11) of the heat engine (MT), the rotor (R) of the electric machine (E) and the two shafts (C1, C2) of the clutch are coaxial so as to rotate about a common axis of rotation (101) parallel to the longitudinal direction (Y) of the vehicle and to the axis of rotation of the output shaft (112) of the gearbox (G).

Description

[0001] The present invention belongs to the field of production of saddle-type motorcycles with two or three wheels, of which only one wheel is the driving wheel. In particular, the invention relates to a saddle-ridden vehicle with hybrid propulsion, ie a vehicle comprising a motor assembly with a heat engine and a reversible electric machine that can be used as an electric motor for increasing the torque available at the drive wheels or as a Generators for recharging battery packs connected to the same electric machine. Background technique [0002] In recent years, two or three-wheeled motorcycles with hybrid propulsion have been proposed, in which an electric machine is added to a common internal combustion engine. The purpose of such a propulsion is basically to utilize the internal combustion engine under efficient conditions and to recover energy by means of the electric motor when decelerating or braking, and possibly using the electric motor alone as the propeller.

Problems solved by technology

[0010] The applicant has noticed that the technical solution mentioned above, as well as other conceptually similar solutions, has some disadvantages, which are caused in particular by the mutual arrangement of the heat engine and the electric motor constituting the hybrid propulsion plant

In particular, the configuration of current propulsion assemblies is particularly complex and bulky, and makes manufacture and installation of propulsion assemblies difficult

These aspects obviously affect the final manufacturing cost

At the same time, the current configuration of the propulsion assembly may also appear less favorable for inspection and / or maintenance operations on the vehicle
