An electrically driven hub includes an electrical mechanism including an electrical motor and a planetary gear system connected to the electrical mechanism. A first fixed shaft is connected to the stator of the electrical motor and a second fixed shaft is connected to a second end of the stator of the electrical motor. The first and second fixed shafts are connected to the vehicle frame. A one-way clutch is connected between a cover of the hub and the planetary gear system so that the hub is rotated when the planetary gear system is activated by the motor.

In an exhaust gas turbocharger for an internal combustion engine comprising a compressor and a turbine interconnected by a shaft in a rotationally fixed manner, and an electric machine which can be connected to the exhaust gas turbocharger via a clutch, the exhaust gas turbocharger can be driven at least temporarily by a disk-shaped flywheel rotatably supported on the shaft and being operable selectively by the turbine and by an electro-dynamic structure for improving the response behavior of the exhaust gas turbocharger.

A clutch actuator structure provided for an internal combustion engine and a hydraulic clutch mechanism for transmitting a rotational driving force of a crankshaft of said engine includes a clutch actuator for controlling an oil pressure for engaging and disengaging the hydraulic clutch mechanism. The clutch actuator structure ensures that noises generated at the times of operation of the clutch actuator for actuating a hydraulic clutch are prevented from being transmitted to the exterior. The clutch actuator structure includes an oil sump part for reserving oil provided in the periphery of a clutch actuator. The clutch actuator is disposed in the oil sump part.

The invention discloses a multifunctional urban road cleaning vehicle. The multifunctional urban road cleaning vehicle consists of a front vehicle body and a back vehicle body, wherein the front vehicle body comprises a sweeping mechanism, a walking mechanism and a rubbish-collecting mechanism; the back vehicle body comprises a seat and man-powered walking mechanism; the sweeping mechanism is a front brush frame which is hinged with the front vehicle body; a balancing beam is arranged on the front brush frame; rotator supporting bases are hinged on the lower parts of two ends of the balancing beam through bevel gears respectively; rotators with cleaning brushes are arranged on the lower parts of the supporting bases; the rotators are driven by a clutch and speed-increasing big chain wheels; the walking mechanism comprises an accumulator on the back vehicle body; small chain wheels are arranged on the accumulator and the motor output shaft; the small chain wheels are connected with the big chain wheels on a back axle through chains; the rubbish-collecting mechanism comprises a collecting frame and sweeping and collecting roller brushes; two sweeping and collecting roller brushes are transversely arranged on the collecting frame in parallel; through the opposite rotation of the sweeping and collecting roller brushes, rubbish is thrown into a rubbish box through an arc hood; the seat and man-powered walking mechanism comprises a vehicle frame; a man-powered pedal and wheels are arranged on the vehicle frame; and the front end of the vehicle frame is hinged with the front vehicle body.

The invention provides a control method and device for the sliding friction torque of a clutch and electronic equipment. The control method for the sliding friction torque of the clutch comprises the steps of expressing and storing a strong nonlinear relation between the clutch sliding friction torque and multiple influence factors through a neural network model; and acquiring clutch target sliding friction torque and the values of influence factors of the clutch target sliding friction torque, and enabling the neural network model to output corresponding clutch target pressure accordingly so as to calculate electromagnetic valve target current to control the clutch. According to the method, more complete clutch sliding friction torque characteristics are expressed by using a smaller storage space, and the storage space is greatly reduced; and online self-learning is performed on the complex torque characteristics of the clutch by using the characteristics of the neural network so as to adapt to the individual deviation of clutch assembly manufacturing and assembling and the performance change after long-term use.
