Clutch device for road sweeper connecting transmission

Abstract

The invention discloses a clutch device making a connection transmission with a sweeping car. A disc type friction clutch is connected between an assistant engine and a transmission shaft, an over-running clutch is connected between the transmission shaft and a belt wheel, the belt wheel is connected with a transmission belt pulley through a triangle belt to rotate to drive a fan to rotate. With the technology of the invention, no impact vibration appears when the fan is started; when the assistant engine suddenly extinguishes, the assistant engine disengages from the transmission connection with the fan immediately, the state which the fan inversely drives the assistant engine to rotate can not appear, and the fan and the assistant engine are protected from being damaged.

Description

technical field [0001] The invention relates to a clutch device for connecting transmission of a road sweeping vehicle, in particular to a double clutch device for connecting a drive fan to an auxiliary engine of the road sweeping vehicle. Background technique [0002] Sweeping suction and pure suction road sweepers generally have two engines. The main engine installed on the chassis drives the vehicle, and the auxiliary engine installed on the frame drives the fan and sweeping operations. It is difficult to start the auxiliary engine when it is connected to the load of the fan. The scheme of starting the auxiliary engine and the fan separately needs to install a clutch device connected to the transmission between them; The operation suddenly shuts down the auxiliary engine, and the fan will continue to rotate due to the inertia of the fan impeller, and the fan will rotate with the turned off auxiliary engine, causing damage to the turned off auxiliary engine and the fan. ...

AI Technical Summary

Problems solved by technology

The deficiencies of this patent are: first, when the engine accelerates to normal speed, the friction plate in the center of the clutch is automatically thrown away and combined with the clutch housing, and the fan starts to rotate, but the fan cannot reach the speed of the synchronous engine transmission from the static state in one step. When the fan starts to rotate, it will drag down the engine speed, and the friction plate in the center of the clutch will reset when the engine speed decreases and the centrifugal force decreases. Connecting, disconnecting, and reconnecting multiple times, the process of starting the fan produces multiple shocks and vibrations; the second is to make the clutch connect stably, the engine's working speed is higher than the clutch connection speed, when the engine suddenly turns off for some reason, The inertia of the fan reverses the rotation of the engine and decays the speed until the friction plate in the center of the clutch is reset, the engine can be disengaged from the transmission connection with the fan, and the process of the fan reverses will have an adverse effect on the engine that has been turned off
