Side-hanging-type double-motor transmission mechanism for electric two-wheel vehicle

Abstract

A side-hanging-type double-motor transmission mechanism for an electric two-wheel vehicle is composed of a main motor, an auxiliary motor and a gear combining piece and is characterized in that the main motor and the auxiliary motor are installed outside a box body on the left side in the front of the electric vehicle; the gear combining piece is composed of a driving gear, a driven gear, a carrier gear, an auxiliary gear and an output shaft and is installed in a decelerating box; the main motor is connected with the driving gear, and the auxiliary motor is connected with the auxiliary gear; the driving gear is engaged with the driven gear, and thus a driving mode for top-speed driving on a normal pavement is constituted; and the auxiliary gear is engaged with the carrier gear, and the carrier gear is engaged with the driven gear, and thus an auxiliary motor assisting driving mode under the load state is constituted.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a dual-motor transmission mechanism of a side-mounted electric two-wheel vehicle. Background technique [0002] Electric vehicles are favored by consumers because of their low carbon, energy saving, and low cost of use. At present, the number of electric vehicles in my country is more than 200 million. After more than ten years of technological progress, the development of electric motorcycles and electric vehicles is gradually emerging. With the continuous expansion of the market, relevant standards for electric motorcycles and electric vehicles are expected to be issued soon. , the user's use requirements are also constantly upgrading. For example, the electric car requires a speed of 75 horses and the quality uncertainty of electric motorcycle racing cars and cargo vehicles. The well-known electric wheel hub motor and differential motor technology, the speed and torque are not ...

Problems solved by technology

Therefore, technicians will begin to study side-mounted high-speed motors. For example, the patent No. 200610138450.2 is a Chinese invention patent for the driving device of two-wheeled electric vehicles. Ten years ago, a transmission scheme in which the main and auxiliary motors drive the driving gear was proposed. The output shafts of the main motor and the auxiliary motor are used to mesh with the drive gear through their respective gears, but this one-stage transmission cannot allow the auxiliary motor to achieve higher speed and greater output torque (maximum output speed) due to the limitation of the transmission ratio. torque is 70n.m), since the main and auxiliary motors are set in the same direction, in order to install the main and auxiliary motors reasonably, the unit volume of the gearbox has to be increased to increase the production cost. After the frame, the one-way bearing 8, bearing 7, 5 are connected with a drive gear 6, so that the drive gear 6 can only drive the central shaft 9 to rotate, but the central shaft 9 cannot drive the drive gear 6 to rotate, but this technology is practical However, it cannot be realized in application, and technicians should clearly realize that the center shaft 9 and the drive gear 6 are fixedly connected. Although the vehicle is in reverse drive, the center shaft 9 and the drive gear 6 are always running synchronously, and it is impossible to realize Free from reluctance while coasting
