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 that a clutch is provided between the power output shaft of the electric motor and the transmission. There can be many specific structures of the above-mentioned devices, and they should all belong to equivalent mechanical structures. Three embodiments are described below in conjunction with the drawings:

[0020] The first embodiment: figure 1 An electric drive mechanism of an electric truck is introduced. As can be seen in the figure, the power output shaft of the electric motor 1 of this electric truck drives the driving wheels 4 through the transmission 3. The characteristic is: the power output shaft of the electric motor 1 and the transmission 3 There is a clutch 2 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 electric motor 1. The driving shaft 6 and the driven shaft sleeve 10 are in clearance fit....

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 heavy-duty vehicle, that is, an electric truck. Background technique [0002] Electricity-powered cars are simple in structure, extensive in energy, low in noise, light in pollution, and controllable. They have developed rapidly in recent years, especially trucks with larger loads, which have begun to be used in mine transportation and other places. However, because the explosive power of the electric motor is not as good as the fuel power, the required power increases greatly when the vehicle starts and when it travels over hurdles. Therefore, it is necessary to adopt a large horse-drawn trolley with high energy consumption. In addition, the existing electric trucks mostly use rigid transmission between the motor and the driving wheels, which has low speed change performance, easy to extinguish fire when encountering obstacles, and the equipment damage is relatively large, and the road smoothness requirements are high. Therefore...
