Embodiment

[0021] like figure 1 The assembly schematic diagram of the electric semi-trailer and the front of the electric semi-trailer equipped with a single-axle electric axle. figure 2 It is an electric semi-trailer equipped with a single-axle electric axle. When the load capacity requirement is small, an electric semi-trailer equipped with a single-axle electric axle is used, including the third battery 4, the semi-trailer compartment 5, the electric drive axle 6-2, and the suspension 7. The electric axle consists of the motor, transmission, differential, axle shafts and wheels. When the vehicle acceleration required by the driver is small, the electric drive axle 6-2 can be engaged in neutral without participating in the driving; when the vehicle acceleration required by the driver is large, the electric drive axle 6-2 can be engaged in the corresponding gear as required Participate in driving; when the vehicle brakes, the electric drive axle 6-2 performs braking energy recovery. ...

Abstract

The invention relates to the field of electric motor driving and new energy commercial vehicles, in particular to an electric semi-trailer with electric driving axles. The electric semi-trailer with the electric driving axle comprises a head, a first battery, a second battery, a third battery, a semi-trailer carriage, electric driving axles and suspensions, wherein the first battery is mounted on the head; the second battery is mounted at the bottom of the head; the third battery is mounted at the bottom of the semi-trailer carriage; and the two electric driving axles are respectively arranged under the head and the semi-trailer carriage through the suspensions. According to the invention, the electric semi-trailer with the electric driving axles are dragged through the electric vehicle head and the number of the electric driving axles of the electric semi-trailer can be changed according to different deadweight capacities; the loading qualities of an electric truck and an electric logistics vehicle can be greatly improved; and meanwhile, the driving range of the electric truck can be also greatly increased.

Description

technical field [0001] The invention relates to the fields of electric motor drive and new energy commercial vehicles, in particular to an electric semi-trailer equipped with an electric drive axle. Background technique [0002] With the development of new energy vehicles, the social demand for new pure electric vehicles such as pure electric trucks and pure electric logistics vehicles is increasing. At present, the pure electric trucks and pure electric logistics vehicles produced by most electric vehicle manufacturers have only two axles, without semi-trailers, the total mass is less than 2.5 tons, and the loading mass is less than 800kg. Due to the limitation of the load quality, too many batteries cannot be installed, so the driving range is also limited. Facing the urgent market demand, it is urgent to provide a solution to improve the loading quality and driving range of pure electric trucks and pure electric logistics vehicles. [0003] In order to improve the loadi...
