Embodiment Construction

[0024] The electric heavy-duty traction special vehicle provided by the invention is refitted on the basis of the existing domestic tractor. As shown in Figure 1, the modification steps include:

[0025] 1. Remove the diesel engine, water tank, fuel tank, intake and exhaust pipes of the original car, and replace them with the electric motor 10 and the controller;

[0026] 2. Keep the original car gearbox and clutch, the output shaft of the motor 10 is connected to the clutch; and a clutch housing is configured, the front end of the clutch housing is connected to the motor housing, and the rear end is connected to the gearbox housing;

[0027] 3. A special power supply 20 is installed between the front and rear wheels and on the outside of the frame, and the two special power supplies 20 are arranged symmetrically;

[0028] 4. Install the electric brake air pump 41 and the power steering pump 42 .

[0029] Of course, in order to meet the needs of special working conditions, t...

Abstract

The invention relates to an electric heavy-duty special tractor consisting of a power system, a chassis, a car body and an electrical device, wherein, the chassis consists of a transmission system, a running system, a steering system and a braking system. The invention is characterized in that: the power system is provided with a special power supply, a motor and a motor controller, wherein, the special power supply is a car double-electric-layer capacitor and is electrically connected with the motor; the motor can run in coordination with the motor controller; an output shaft of the motor is connected with the transmission system. The electric heavy duty special tractor has big starting torque which can start a heavy-duty automobile with a load of 60 tons and coordinate with a rapid charging station, in particular to carrying out distance transportation operation in a region densely using the heavy-duty automobiles.

Description

technical field [0001] The invention relates to an electric traction vehicle, in particular to the front of the electric traction vehicle. Background technique [0002] In many areas where heavy-duty vehicles are intensively used, such as cargo hauling at ports and wharves, vehicles need to run back and forth within a small distance (such as 1-3Km), and the speed requirement is not high (generally 30km / h), but the vehicles need to keep making Stop, start, accelerate, decelerate and other actions. Due to the use of internal combustion engine vehicles at home and abroad, the noise and thick smoke cannot be avoided, causing the noise decibels in the working environment to exceed the standard, and the air is full of smoke, which makes it difficult for the staff to breathe and low visibility, which not only endangers the health of the staff , and lead to an increase in the rate of work accidents. [0003] This problem has existed for many years, and there has been no good way t...
