Environment-friendly motor-driven coach car for driving schools

Abstract

The invention relates to an environment-friendly motor-driven coach car for driving schools. The dynamic system assembly of the coach car comprises a motor, a motor control circuit, a transmission connection mechanism, a fixed support, an enclosure, a transmission shaft and the like. An engine is removed, and a flywheel, a clutch, a transmission gear and the like are kept; after configuration, power is supplied for an electrocar by a storage cell, and the electrocar is driven by the motor to drive; in the driving process, a driver steps on the clutch to shift gears; the motor and a motor speed regulation control circuit are connected with the enclosure in an insulated mode; the output shaft of the motor is connected with the flywheel and the clutch by a transmission mechanism; an originalvacuum servobrake pump is changed into a customized direct-current vacuum servobrake pump; and the original hydraulic assistance steering pump is changed into a customized direct-current hydraulic assistance steering pump. The coach car satisfies the training requirements of drivers, is simple and effective to control driving operation, is reliable in working and safe in travelling, and has durable mechanical devices and electric devices and small possibility of maintaining, and the product can be subjected to on-batch trail production and demonstration run.

Description

technical field [0001] The invention relates to a coach car for driving schools, in particular to an environment-friendly electric coach car for driving schools. Background technique [0002] With the development of fuel vehicles, energy is becoming increasingly scarce, and the pollution of vehicle exhaust is becoming more and more serious. The country has incorporated energy conservation and emission reduction into its national policy. In order to save energy and reduce emission pollution, electric coach cars are used instead of fuel cars for teaching. [0003] The patent application with the application number "200920009922.3" discloses a special electric coach car for driving school learning. The patented power supply is drawn from one of the battery packs to a 12V power supply, which will lead to uneven discharge of the battery, reduce the capacity of the battery pack and easily damage the battery; The electricity meter is used to display the current, which cannot preve...

[0003] The patent application with the application number "200920009922.3" discloses a special electric coach car for driving school learning. The patented power supply is drawn from one of the battery packs to a 12V power supply, which will lead to uneven discharge of the battery, reduce the capacity of the battery pack and easily damage the battery; The electricity meter is used to display the current, which cannot prevent accidents caused by abnormal voltage; the use of ordinary DC motors cannot meet the power output characteristics of the coach car; the braking system and steering system are exactly the same as the original fuel car, and its power source cannot be guaranteed; use the key switch S1 , potentiometer S2 and fine-tuning potentiometer R3, which cannot fully simulate the opening and acceleration performance of the original fuel vehicle

[0004] The patent application with the application number "200820133083.1" discloses a control device for electric coaches. The control device includes a casing, a high-voltage part and a low-voltage control part, wherein the casing is made of waterproof and high-pressure resistant PVC; the high-voltage part includes a high-voltage power input line, AC contactor and high-voltage power output line; the low-voltage control part includes motor current control device, control relay K1, control relay K2, photoelectric sensor, start level, logic discriminator, delayer and power modulator, among which, the motor The current control device includes AC transformer, AC / DC converter, power or voltage comparator and potentiometer. The power supply modulator also reserves an expander. The high-voltage part plays the role of turning on and off the working current of the motor. The voltage of the high-voltage part It is 380V. The voltage modulated by the power modulator is supplied to the low-voltage part. The voltage of the low-voltage part is 12V. It adopts 380V high voltage, which is a wired power supply, which limits the driving distance, and the safety is not high, the energy utilization rate is low, and the neutral and Motor braking for energy recovery
