Detailed Description
The following detailed description of embodiments of the present invention will be made with reference to the accompanying drawings:
a fluid coupling, also called a fluid coupling, is a fluid transmission device for connecting a power source (usually an engine or an electric motor) and a working machine and transmitting torque by a change in fluid momentum torque.
and a first hydraulic coupler 5 integrated with a belt pulley 7 is adopted at the tail end of power transmission, and the belt pulley 7 is fixed on a turbine of the first hydraulic coupler 5 and is driven by the turbine to rotate. Specifically, a rear power takeoff of an engine 1 is connected with a friction plate clutch 3 through a transmission shaft 4, the friction plate clutch 3 is connected with a transfer case 4, and an output port of a main shaft of the transfer case 4 is connected with a first hydraulic coupler 5 of an integrated belt pulley 7.
When a chassis engine is started, the engine runs in an idling mode at the moment, after the friction plate clutch 3 is connected, power is transmitted to the transfer case 4 from a power takeoff behind the engine 1, a main shaft of the transfer case 4 outputs power to drive the first hydraulic coupler 5 and the belt pulley 7 to work, because the belt pulley 7 integrated on the first hydraulic coupler 5 needs to drive the fan to work, the fan has larger rotational inertia, the soft start of the fan can be realized by utilizing the high buffering performance of the first hydraulic coupler 5 at the moment, and the problems that the friction plate clutch 3 is damaged or the engine stalls and the like caused by impact are solved.
When a brake pedal is stepped down to brake, the chassis engine 1 is decelerated to an idle speed, the fan is decelerated slowly to an idle speed working state by utilizing the high buffering performance of the hydraulic coupler I5, and the upper assembly is kept to work continuously and stably by utilizing the power output by the idle speed.
In embodiment 2, referring to fig. 4, another power transmission is to add a second hydraulic coupler 6 in the middle of a transmission line, and a turbine of the second hydraulic coupler 6 drives the transfer case 4 to work. Specifically, the rear power takeoff of the engine 1 is firstly connected with the friction plate clutch 3, the friction plate clutch 3 is connected with the second hydraulic coupler 6 through the transmission shaft 2, the second hydraulic coupler 6 is fixed on the transfer case 4, and the output port of the main shaft of the transfer case 4 is connected with the belt pulley 7.
When the chassis engine 1 is started, the engine runs at an idle speed, after the friction plate clutch 3 is switched on, power is transmitted to the second hydraulic coupler 6 from a power takeoff behind the engine 1, the transfer case 4 is driven to work by a turbine of the second hydraulic coupler 6, and finally the power is transmitted to the fan; the second fluid coupling 6 functions as the first fluid coupling.
When the brake pedal is stepped on to brake, the engine of the chassis is reduced to idle speed, and the hydraulic coupler plays the same role as the scheme I.
A power transmission system installed on a single-engine sanitation truck comprises a whole transmission line arranged behind a chassis engine 1.
