Problems solved by technology

In addition, the existing electric trucks mostly use rigid transmission between the motor and the driving wheels, the speed change performance is low, it is easy to extinguish fire when encountering obstacles, the damage to the equipment is also relatively large, and the requirements for the smoothness of the road are relatively high.
Therefore, electric trucks with large loads have not been popularized

Embodiment Construction

[0019] The general idea of ​​the present invention is: a clutch is arranged between the power output shaft of the electric motor and the transmission. The specific structure of the above-mentioned device can have many kinds, all should belong to equivalent mechanical structure. Introduce three kinds of embodiments below in conjunction with accompanying drawing:

[0020] The first embodiment: figure 1 An electric driving mechanism of an electric truck is introduced. It can be seen in the figure that the power output shaft of the electric motor 1 of this electric truck drives the driving wheel 4 through the transmission 3. Its characteristics are: the power output shaft of the electric motor 1 and the transmission 3 There is a clutch 2 in between. combine figure 2 It can be seen that the clutch 2 is a centrifugal clutch 5 . The driving shaft 6 of the centrifugal clutch 5 is the power output shaft of the motor 1, and the driving shaft 6 and the driven shaft sleeve 10 are in ...

Abstract

The invention relates to a load-carrying vehicle, i.e. an electric truck. Power output shafts of motors (1) drive driving wheels (4) through speed changers (3); and the electric truck is characterized in that clutches (2) are arranged between the power output shafts of the motors (1) and the speed changers (3). The electric truck has the beneficial effects that rigid driving is changed into flexible driving, so that automatic speed adjustment is realized; when the electric truck is started or passes through a ridge, the rotating speed can be automatically reduced, and the traction is increased, so that the capacity of crossing an obstacle is obviously improved; the specification of the same type of motor is substantially reduced, the working performance is stable and reliable, and the engine is not liable to stop; and the electric truck is particularly suitable for high-load transportation such as a mine.

Description

technical field [0001] The invention relates to a load-carrying vehicle, that is, an electric truck. Background technique [0002] Vehicles powered by electricity have a simple structure, a wide range of energy sources, low noise, and light and controllable pollution. They have developed rapidly in recent years, especially trucks with large loads, which have begun to be used in mine transportation and other places. However, since the explosive power of the electric motor is not as good as that of the fuel, the required power increases greatly when the vehicle starts and goes over the hurdles, so it needs to be equipped with a large horse-drawn cart, which consumes a lot of energy. In addition, the rigid transmission between the motor and the driving wheels of the existing electric trucks is often used, the speed change performance is low, it is easy to extinguish the fire when encountering obstacles, the damage to the equipment is also relatively large, and the requirements ...
