Description

Electric locomotive structure that improves motor efficiency

technical field

The utility model relates to an electric locomotive structure for improving motor efficiency, in particular to a gear box for directly using an old or new fuel engine vehicle, refitting an electric motor as a power source to drive a gear box for fuel engine vehicles The high-quality speed change effect of the original transmission gearbox enables the electric motor to produce the most suitable driving speed when the vehicle starts and various driving states, thereby enabling the electric motor to achieve the best output efficiency, greatly reducing power consumption and improving battery life.

Background technique

By the way, the existing electric vehicles have failed to substantially replace the market sales of fuel vehicles, which 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 shortcoming: insufficient battery life , the charging time is too long, the starting torque is insufficient, and the cost of high-performance vehicles is too high. Therefore, before the power storage device is improved, the fastest and most effective way is to change the driving mode of the motor. The method is roughly divided into: (1) direct drive, (2) reduction gear drive, (3) belt type CVT drive. The characteristics and disadvantages of the driving methods of electric vehicles currently sold in the market are briefly described as follows:

(1) Direct drive mode:

Its simple structure, no complicated transmission system, and low cost are the methods used by many electric vehicles, but it is also the one that has the greatest gap with actual use; when using a motor with a smaller horsepower, although it consumes less current The low-speed stage is easier to control, but the actual urban driving situation is the road condition with frequent forwards and stops, which will cause the motor to draw a large amount of power from the battery in order to overcome the inertia during the initial stage of the vehicle due to the small horsepower and longer start time. When going to a road section with a slope, the torque output is increased due to the inability to change the speed, which greatly shortens the mileage.

Although increasing the horsepower of the motor can improve the above shortcomings, in addition to increasing the power consumption, the high horsepower output will easily cause the risk of bursting when the vehicle is just starting, making it difficult for ordinary drivers to operate.

(2) Fixed reduction gear ratio drive mode:

Its system uses a high-speed motor with a reduction gear to improve the ability to start at low speeds, but a fixed-ratio reduction gear set is difficult to meet both low-speed and high-speed driving needs (when an electric vehicle is running at high speed, the driver can only increase the motor speed, The high-speed operation of the motor will generate high temperature, which will cause the motor to consume more power and greatly reduce the cruising distance of the electric vehicle).

(3) Belt type CVT drive mode:

It adopts two sets of V-groove turntables to clamp the transmission belt, and uses the speed of the motor to change the centrifugal force of the V-groove turntables, and further changes the diameter ratio of the turntables to complete the deceleration ratio.

The V-groove turntable must clamp the drive belt to prevent slippage between the belt and the turntable, which is prone to high friction and high heat dissipation, resulting in a large amount of energy loss and greatly reducing the cruising distance of the electric vehicle.

Furthermore, general fuel engine vehicles, as shown in Figure 8 and Figure 9, rely on the collocation of clutch 73 and transmission gearbox 8, and rely on cylinder 7, crank 71 and crankshaft 72 to produce the best driving effect, and obtain fuel-efficient Purpose, 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 can play the best effect, reduce power consumption and increase the voyage, which is the purpose of this utility model The main purpose of the invention.
