Problems solved by technology

[0005] At present, the power drive system of the existing pure electric logistics vehicles with front front drive is all set on the frame chassis, specifically on the sub-frame. The sub-frame has the functions of placing the power drive system and connecting the front suspension. The structure of the existing sub-frame is the same as that of a gasoline vehicle, and there is no special structure, which makes the chassis space of the frame after the power drive system is placed takes up a lot and the center of gravity is relatively high

Embodiment 1

[0099] See Figure 1 to Figure 7 , The electric logistics vehicle of this embodiment includes a chassis 1, a power drive system 2, a subframe 3, a sunken rear axle 4 and a truck body 5. The chassis 1 includes a front bearing part 1-1, a middle bearing part 1-2 and a rear bearing part 1-3. The auxiliary frame 3 and the sunken rear axle 4 are installed on the front bearing part 1-1 and the rear bearing part 1-3 respectively. The power drive system 2 is arranged on the auxiliary frame 3 . The truck body 5 is installed on the chassis 1 .

[0100] The middle bearing part 1-2 of the chassis 1 includes a load-bearing frame 1-2-1 and a middle connecting rod assembly 1-2-2. There are multiple middle connecting rod assemblies 1-2-2, multiple load-bearing frames 1-2-1 are arranged side by side, and a middle connecting rod assembly 1 is passed between every two adjacent load-bearing frames 1-2-1 -2-2 connections. A storage space is formed between every two adjacent bearing frames 1-2...

Embodiment 2

[0139] This embodiment is basically the same as Embodiment 1, except that: the speed ratio of the first input gear set and the speed ratio of the second input gear set of the transmission mechanism 2 - 3 of the power drive system 2 are the same.

Embodiment 3

[0141] This embodiment is basically the same as Embodiment 1, the difference is:

[0142] See Figure 8and Figure 9 . It also includes a truck body 5 installed on the chassis 1 . The truck body 5 includes a compartment frame, a compartment panel 5-1, a compartment door 5-2 and a chassis compartment door 5-3. The compartment panel 5-1 is laid on the compartment frame. The compartment frame includes a front wall frame 5-4, a rear wall frame 5-5, a roof frame 5-6, a side wall frame 5-7 and a connector 5-8. Both ends of the roof frame 5-6 are connected to the front frame 5-4 and the rear frame 5-5. There are two side frame frames 5-7, and the two side frame frames 5-7 are fixed to both sides of the roof frame frame 5-6 by a plurality of connectors respectively. Edges at both ends of the side frame 5-7 are respectively connected to the front frame 5-4 and the rear frame 5-5. The compartment door 5-2 is located on the back wall frame 5-5. The chassis door 5-3 is arranged on...

Abstract

The invention discloses an electric logistics vehicle comprising a chassis, a power driving system, an auxiliary frame, a sunken type rear axle and a wagon box body. The chassis comprises a front bearing portion, a middle bearing portion and a rear bearing portion; the auxiliary frame and the sunken type rear axle are mounted on the front bearing portion and the rear bearing portion correspondingly; the power driving system is arranged on the front bearing portion and / or the rear bearing portion; and the wagon box body is mounted on the chassis. The electric logistics vehicle is ingenious in structure, the power driving system on the chassis can achieve a front-mounted front-wheel drive, a rear-mounted rear-wheel drive or independent four-wheel-drive manner, the operating efficiency of thedrive system is achieved, and the performance requirements of the vehicle is met.

Description

technical field [0001] The invention relates to an electric logistics vehicle. Background technique [0002] New energy vehicles, especially pure electric logistics vehicles, have developed rapidly in recent years. Today's pure electric logistics vehicle drive system configuration basically adopts a single motor combined with a single gear ratio drive mode. This drive system configuration uses a single reduction ratio and a single drive motor. The speed of the drive motor is in a fixed proportional relationship with the vehicle speed. , using the method of controlling the speed change of the motor to drive the vehicle to change the speed has obvious disadvantages: in order to ensure the dynamic performance of the vehicle, the power margin of the driving motor is large, and the motor is only used for a short time when accelerating or accelerating on a steep slope The problem of peak power reserve at this time is that when the vehicle is running normally, the speed of the dri...
