Abstract
The utility model relates to an electric vehicle test bench, which comprises a bench frame, a storage battery, a power motor, an accelerator pedal switch, a transmission shaft, a speed changer, wheels and an earth leakage protector, wherein the storage battery directly supplies power source for the power motor to further lead an engine to drive the electric vehicle to run; the rotating speed of the power motor is directly controlled by the accelerator pedal switch; and the earth leakage protector protects the storage battery. The electric vehicle test bench can be used as a method for displaying the whole system in a plane manner, leading each device to be visual and clear, avoiding complexity and difficulty in vehicle operation, and brining convenience for learners to visually observe the working principle and running state of each part of the electric vehicle and clear various faults.
Description
Technical field
The utility model belongs to exploitation teaching equipment field, relates to a kind of electric automobile experiment table, the principle of work of electric automobile is simplified to synthesize carry out analog demenstration on test bench, thereby reach the purpose of being convenient to impart knowledge to students.
Background technology
Along with industrial expansion and growth in the living standard, automobile has become a kind of important vehicles, car owning amount rapidly rises, but exhausted and atmospheric pollution situation is increasingly serious along with petroleum resources in recent years, the electric automobile of clean environment firendly becomes present research emphasis, and the internal-combustion engines vehicle that substitutes current a large amount of uses with the no exhaust emission automobile of Nover practical has great realistic meaning.
The composition of electric automobile comprises mechanical systems such as driven by power and control system, driving force transmission, finishes the equipment of set task etc., and driven by power and control system are the cores of electric automobile, also is difference and the maximum difference of internal-combustion engines vehicle.Driven by power and control system are made up of speed-regulating control device of driving motor, power supply and motor etc.Yet each big-and-middle School of High Profession Technology lectures real vehicle in explanation electric automobile principle of work and has certain difficulty really at present, and therefore designing a workbench that satisfies power system of electric automobile structure, principle of work, to solve the teaching practice difficulty very urgent.
Summary of the invention
Problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of electric automobile experiment table is provided, and the electric automobile principle of work is simplified to synthesize carry out analog demenstration on test bench.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of electric automobile experiment table that provides according to the utility model; comprise stand, battery pack, power motor, throttle foot pedal switching plate, transmission shaft, variator, wheel, earth leakage protective device; accumulator (2), power motor (3), electric machine controller are housed in the described stand; battery pack connects motor and electric machine controller, continues to connect transmission shaft (5), variator (4) and wheel (6).
Described battery pack provides power supply for motor, by the battery-powered amount of accelerator pedal switch (1).
Described variator connects transmission shaft, and transmission shaft connects wheel.
Described earth leakage protective device is installed on the stand.
The utility model compared with prior art has significant advantage and beneficial effect.
The utility model can be used as to be showed total system with the form on plane, each installs simple and clear, avoid the complicated and difficult of real vehicle operation, be convenient to each parts principle of work, operating condition that the student observes electric automobile intuitively, and the method for discharging various faults.Be more convenient for intuitively, simply lecture teaching to the student.
Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, embodiment, structure, feature and effect thereof that foundation the utility model is provided, describe in detail as after.
See also Fig. 1; a kind of electric automobile experiment table; comprise stand, battery pack, power motor, throttle foot pedal switching plate, transmission shaft, variator, wheel, earth leakage protective device; accumulator (2), power motor (3), electric machine controller are housed in the described stand; battery pack connects motor and electric machine controller, continues to connect transmission shaft (5), variator (4) and wheel (6).
Described battery pack provides power supply for motor, by the battery-powered amount of accelerator pedal switch (1).
Described variator connects transmission shaft, and transmission shaft connects wheel.
Described earth leakage protective device is installed on the stand.
What connect battery pack and d.c. motor is a simple throttle foot pedal switching plate.If the throttle foot pedal switching plate is reached maximum, then this controller can be sent to power motor with the whole voltages from accumulator.Promptly disconnect if the throttle foot pedal switching plate is reached minimum, then this throttle foot pedal switching plate can not transmit voltage to power motor.The throttle foot pedal switching plate links to each other with a pair of pot (variohm), and these pots can send signal, and it thinks the electric power that may transmit to inform controller.The throttle foot pedal switching plate can not transmit electric power (when stopping automobile), transmits whole electric power or between any electric power rank between these two, two pots has been installed in the electric automobile.Controller will read these two pots and guarantee that the signal of the two is identical.If the signal difference of the two, then the throttle foot pedal switching plate can not move.Arrange like this is in order to prevent the situation that a pot lost efficacy in full up position to take place.
Claims (4)
