The present disclosure relates to the field of all-terrain vehicles and, more particularly, to a hybrid all-terrain vehicle.
All-terrain vehicles in the related art are usually fuel-driven or hybrid-driven, which are relatively environmentally unfriendly to use and less competitive in the market, and the cost of using fuel-driven vehicles is high.
A hybrid all-terrain vehicle according to embodiments of the present disclosure includes: a vehicle frame; a front wheel coupled to a front part of the vehicle frame; a rear wheel coupled to a rear part of the vehicle frame; a drive motor arranged on the vehicle frame; an engine assembly arranged on the vehicle frame and providing electric energy to the drive motor, the engine assembly including a crankshaft, and an axis of the crankshaft being perpendicular to a longitudinal centrosymmetric plane of the hybrid all-terrain vehicle; and a drive shaft extending along a front-rear direction of the vehicle frame and drivingly coupled to the drive motor to transmit a driving force of the drive motor to the front wheel or the rear wheel.
A hybrid all-terrain vehicle according to other embodiments of the present disclosure includes: an engine and an electric generator being operatively coupled as an engine assembly; and a drive motor and a gearbox being operatively coupled as an electric drive assembly.
These and/or other aspects and advantages of embodiments of the present disclosure will become apparent and more readily appreciated from the following descriptions made with reference to the drawings, in which:
Embodiments of the present disclosure will be described in detail below. The embodiments described below with reference to the accompanying drawings are exemplary.
A hybrid all-terrain vehicle 100 according to embodiments of the present disclosure will be described below with reference to
In some embodiments, the front wheel is coupled to a front part of the vehicle frame 110 and the rear wheel is coupled to a rear part of the vehicle frame 110. The drive motor 140 is arranged on the vehicle frame 110. The engine assembly 130 is arranged on the vehicle frame 110 and provides electric energy to the drive motor 140. The engine assembly 130 includes a crankshaft having an axis 133 perpendicular to a longitudinal centrosymmetric plane 150 of the hybrid all-terrain vehicle 100. The drive shaft 120 extends along a front-rear direction of the vehicle frame 110 and is drivingly coupled to the drive motor 140 to transmit a driving force of the drive motor 140 to the front wheel or the rear wheel.
It can be understood that not all straddle-type all-terrain vehicles have a cockpit, and the present solution is applicable to three types of all-terrain vehicles. Although all-terrain vehicles having the cockpit are mentioned in the description of the present solution, the application of the present solution to other all-terrain vehicles without any cockpit can be simply deduced by those skilled in the art and hence also fall into the protection scope of the present solution, which will not be repeated here.
The engine assembly 130 is configured to provide electric drive to drive the drive motor 140 to rotate. The power of the drive motor 140 can be transferred to the front wheel or the rear wheel through the drive shaft 120 to drive the all-terrain vehicle 100 to travel.
For the hybrid all-terrain vehicle 100 according to the embodiments of the present disclosure, by arranging the engine assembly 130 and the drive motor 140 on the vehicle frame 110, the engine assembly 130 can provide electric power to enable the drive motor 140 to operate, so that the hybrid all-terrain vehicle 100 can be electrically driven, allowing the hybrid all-terrain vehicle 100 to be used more environmentally friendly and become more competitive in the market.

In some embodiments, the axis 141 of the drive motor 140 and the axis 133 of the crankshaft are both located above the drive shaft 120. A vertical distance between an axis 1311 of an engine 131 of the engine assembly 130 and the axis of the drive shaft 120 is L1, and a vertical distance between the axis 141 of the drive motor 140 and the axis of the drive shaft 120 is L2, in which L1>L2. It can be understood that the drive motor 140 is closer to the drive shaft 120, enabling the power of the drive motor 140 to be transmitted to the drive shaft 120 more quickly, and enhancing the performance of the hybrid all-terrain vehicle 100.
In some embodiments, a gearbox is arranged between the drive motor 140 and the drive shaft 120, and the gearbox and the drive motor 140 are operatively coupled and form an electric drive assembly 180. It can be appreciated that the gearbox is used for rotation speed adjustment, to make the operation of the drive motor 140 more stable and reliable, and power can be better transferred to the drive shaft 120 to make the operation of the drive shaft 120 more stable and reliable. Further, the gearbox can be integrated into the drive motor 140 to make the structure of the all-terrain vehicle 100 more compact.
As shown in
Further, the longitudinal centrosymmetric plane 150 passes through the middle part of the engine assembly 130. It can be appreciated that the middle part of the engine assembly 130 is in the same plane as the longitudinal centrosymmetric plane 150. As a result, the engine assembly 130 is in the same plane as the drive motor 140, allowing the drive motor 140 to better receive the electric drive from the engine assembly 130, improving the performance of the drive motor 140 and prolonging the service life of the drive motor 140.
In some embodiments, the engine assembly 130 includes an engine 131 and an electric generator 132. The electric generator 132 includes a generator shaft. The crankshaft is arranged in the engine 131, and the crankshaft is drivingly coupled to the generator shaft to drive the electric generator 132 to generate electric energy. An axis of the generator shaft is parallel or perpendicular to the longitudinal centrosymmetric plane 150. It can be appreciated that the engine 131 is configured to drive the electric generator 132 to rotate, thereby generating electric power to rotate the drive motor 140, and enabling the hybrid all-terrain vehicle 100 to operate for use.
