CVT (constant-voltage transformer) driving system and motorcycle

Abstract

The invention discloses a CVT (constant-voltage transformer) driving system and a motorcycle. The CVT driving system comprises an engine and a CVT, wherein a driving shaft of the CVT and a driven shaft of the CVT are parallel to each another and are in transmission fit with each other; and the driven shaft of the CVT is positioned above the driving shaft of the CVT. Because the driven shaft of the CVT is placed above the driving shaft of the CVT, the mounting distance is shortened. The CVT driving system has a compact mounting structure, and is applicable to a motorcycle (particularly a three-wheeled motorcycle); the overall arrangement of the whole motorcycle is coordinated; safety requirements on shock absorption of the motorcycle can be well met; the CVT and the engine can be mounted on a driving portion together and are used for directly driving wheels; because the whole size of the CVT driving system is reduced, mounting space is reduced, the CVT driving system is mounted and arranged conveniently, and the manufacturing cost of whole driving equipment is saved; and because the CVT driving system has an inclined structure, an air convection principle can be implemented in the CVT shell, namely, hot air ascends and cold air descends in the CVT shell, the CVT shell is suitable for convection flowing of heat, heat dissipation of the heat dissipation channel is smooth, and heat dissipation on the CVT transmission mechanism is facilitated.

Description

technical field [0001] The invention relates to a motorcycle transmission system and the motorcycle, in particular to a CVT drive system and the motorcycle. Background technique [0002] CVT (continuously variable transmission) used in motor vehicles has good economy, power and driving comfort, and reduces emissions and costs. Therefore, there are also technical solutions for using it in motorcycles in the prior art, thereby improving the quality of motorcycles. economic performance of the car. In the prior art, the CVT is used in the installation of motorcycles (including three-wheeled motorcycles). In order to ensure the standardization and versatility of the installation, the CVT and the engine are installed horizontally, that is, the drive shaft of the CVT (the power output of the engine) Segment axis) line and the axis of the driven shaft of CVT are in the same horizontal plane, which is convenient for installation and transmission. For motorcycles, the arrangement sp...

Problems solved by technology

For motorcycles, the arrangement space for the engine and CVT is limited, especially for the structure where the drive is directly output to the wheels (directly through the differential), due to the limited space and the need for stable and firm suspension, the horizontal arrangement The transmission structure makes the installation of the engine and CVT uncoordinated, which affects the shockproof, compactness and safety performance of the whole vehicle; at the same time, the layout structure between the main and driven shafts of the existing CVT adopts a horizontal parallel method for placing two The housing cavity between the two is also horizontal; due to the transmission of the CVT structure, more heat will be generated. normal long-term operation of
