Control system and method of transmission system and electric cleaning and sweeping vehicle

Abstract

The invention discloses a control system and method of a transmission system and an electric cleaning and sweeping vehicle. According to the control system and method of the transmission system and the electric cleaning and sweeping vehicle, a high-pressure water pump is in driving connection with a motor through an electromagnetic clutch, the electromagnetic clutch can be controlled to be poweredon or powered off and disengaged according to the operation mode of the cleaning and sweeping vehicle, the response speed is higher, and the combination effect is not easily affected by external factors. Moreover, the motor is controlled to operate at a low speed in the starting operation stage, so that the sawtooth-shaped electromagnetic clutch can be completely meshed during attraction, the electromagnetic clutch is prevented from bearing overlarge torque due to acceleration when not completely meshed, and the electromagnetic clutch is effectively protected; belt abrasion and slipping caused by sudden acceleration of the narrow V-belt mechanism in a zero-speed state can be avoided, different control strategies are formulated according to whether the high-pressure water pump operates ornot after operation is completed to control the motor to decelerate and stop, and tooth beating abrasion of the electromagnetic clutch caused by reverse rotation of the motor is avoided while the deceleration efficiency is guaranteed; and the service life of the electromagnetic clutch is prolonged.

Description

technical field [0001] The present invention relates to the technical field of sanitation machinery, in particular to a control system and method for a transmission system, and in particular to an electric sweeper using the above-mentioned control system. Background technique [0002] With the progress of sanitation equipment, the urban roads in my country have basically realized mechanized cleaning operations. Sanitation equipment such as sweepers, sweepers and sprinklers are widely used in urban road cleaning operations, among which sweepers are currently the most widely used. One of sanitation equipment. [0003] The fan and high-pressure water pump in the transmission system of the existing sweeping vehicle are all driven and controlled by the pneumatic clutch, and the pneumatic clutch is supplied by the chassis air source. The response speed of the pneumatic clutch is relatively slow, and the combination effect of the pneumatic clutch is affected by the chassis. The inf...

Problems solved by technology

[0003] The fan and high-pressure water pump in the transmission system of the existing sweeping vehicle are all driven and controlled by the pneumatic clutch, and the pneumatic clutch is supplied by the chassis air source. The response speed of the pneumatic clutch is relatively slow, and the combination effect of the pneumatic clutch is affected by the chassis. The influence of the air source, because the chassis air source is mainly used for the braking system of the commercial vehicle chassis, the gearbox, the air valve control of the washing and sweeping vehicle, and the drainage in winter, while the air source of the electric vehicle is provided by the electric air pump. If the power of the electric air pump If the air pressure is too small, the gas supply will be slower after the air source pressure is reduced, resulting in low air pressure, so the combination effect of the pneumatic clutch is unstable
