Description

Electric locomotive structure for improving motor efficiency

The invention relates to a structure of an electric locomotive for improving the efficiency of a motor, in particular to a transmission gearbox of an old or new fuel-engine vehicle, which is modified to use an electric motor as a power source to drive the transmission gearbox to borrow the original speed of the fuel-engine vehicle. The gearbox's high-quality shifting effect enables the electric motor to generate the most suitable driving speed at the start of the vehicle and in various traveling states, thereby enabling the electric motor to achieve the best output efficiency, greatly reducing power consumption and improving endurance.

According to the knowledge, the failure of electric vehicles to significantly replace the market sales of fuel vehicles means that the performance of electric vehicles still cannot meet the practical needs of consumers. The main reason is that the development of electric vehicles has continued to improve its main disadvantages: insufficient battery life. , The charging time is too long, the starting torque is not enough, and the cost of high-performance vehicles is too high, so before the power storage device was not improved, the fastest and most effective way is to change the drive mode of the motor. Divided into: (1) direct drive, (2) reduction gear drive, (3) belt-type CVT drive. The characteristics and disadvantages of electric vehicle driving methods currently on the market are briefly described as follows:

(1) Direct drive method: Its simple structure, no complicated transmission system, and low cost are the methods used by many electric vehicles, but it is also the one with the largest difference from actual use. When a motor with a lower horsepower is used, although the current consumed Less, it is easier to control from the start to the low speed, but the actual driving situation in urban areas is the frequent forward and stop road conditions, which will cause the starting time to be longer due to less horsepower and cause the motor to start. The battery draws a large amount of power, and the torque output is increased due to the inability to change speed on sections with gradients, which significantly reduces the mileage.

Although increasing the horsepower of the motor can improve the above disadvantages, in addition to the increase in power consumption, high horsepower output will easily cause the risk of bursting at the beginning of the vehicle, making it difficult for ordinary drivers to manipulate.

(2) Fixed reduction gear ratio driving method: It uses a high speed motor with reduction gear to improve the ability to start to low speed, but a fixed ratio reduction gear set cannot meet the driving requirements of low speed and high speed at the same time (electric vehicles run at high speed) At this time, the driver can only increase the speed of the motor, and the high-speed operation of the motor will generate high temperature, which will cause the motor to consume higher power and greatly reduce the range of the electric vehicle.

(3) Belt-type CVT drive method: It uses two sets of V-groove turntables to clamp the drive belt. The rotation speed of the motor is used to change the centrifugal force of the V-groove turntables and further change the diameter ratio of the turntables to complete the deceleration. proportion.

The V-groove turntable must clamp the drive belt to prevent slipping between the belt and the turntable, so it is prone to high friction and high heat dissipation, which causes a lot of energy loss, and also greatly reduces the range of electric vehicles.

Furthermore, the general fuel-engine vehicles, such as the eighth and ninth diagrams, are matched by the clutch (73) and the transmission gearbox (8), and the cylinder (7), the crank (71), and the crankshaft ( 72) In order to produce the best driving effect and get the purpose of saving fuel, but the fuel engine will emit a large amount of exhaust gas, causing air pollution, but how to remove the pollution problem of the fuel engine, and use its variable-speed gearbox to make the electric motor maximize its effectiveness Reducing power consumption and increasing range are the main invention objectives of the present invention.
