Abstract

This invention provides a self loop pump type dynamic transmitter that can transmit dynamic force. It mainly relates to all kinds of clutches, transmission, brake and other assembly product. The technique plan is that liquor entrance and exit ends of hydraulic pump 1 are directly connected by a cast channel 2, a control valve 6 is set at channel central part and is driven by a motor 7, inside the self loop system is filled with liquor. When the valve 6 is opened, the pump axis 5 can rotate freely relative to the pump block 1, and when the valve 6 is closed, the liquor in channel 2 meets maximum resistance and the pump axis 5 can not move. The value of resistance of the self loop system can be controlled by adjusting the position of the valve 6, then the pump axis 5 and the pump block 1 can be placed all kinds of relative states. Different applications and different capability clutches, brakes and stepless transmissions and other dynamic transmitting product can be designed and made by using the pump axis 5 and the pump block 1 shell as the two action ends of dynamic transmitting.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic diagram of the hydraulic working principle of the present invention; Fig. 2 is a schematic view showing the structure and working principle of the present invention. detailed description

The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments - Figure 2: 1-pump body, 2-communication pipe, 3-connecting shaft, 4-front cover, 5-pump shaft, 6-control wide , 7-motor. As shown in Fig. 2, the control valve 6 is installed in the middle of the pipe 2, and the two ports of the pipe 2 are respectively connected with the liquid inlet and outlet ends of the pump body 1, and the connecting shaft 3 is fixed with the pump body 1 by screws, and its axial position is The pump shaft 5 is concentric, and the shaft of the motor 7 is coupled to the lead screw of the control valve 6.

Working principle: The connecting shaft 3 of the pump body 1 is fixed as the input end of the power, and the pump shaft 5 is used as the power output end, then the specific working principle -

1. When the control valve 6 (driven by the motor 7) is closed, the flow rate q0 of the liquid medium in the connecting passage 2 is calculated according to the hydraulic formula q-vn, V is the displacement, n is the rotational speed, and the rotational speed n is zero. That is, the pump shaft 5 is stationary with respect to the pump body 1. Equivalent to the hard drive, the pump shaft 5 has the highest speed output.

2. When the control valve 6 is fully open, there is no pressure at the inlet and outlet of the hydraulic pump. According to the hydraulic formula, Po=p.q/60, Po output power, p is the pressure. When the pressure is zero, the output power is zero. At this time, the pump shaft 5 is freely rotatable relative to the pump body 1, and the power transmission is in a separated state, and the rotational speed is zero.

3. When the control valve is closed by /f, the damping of the flowing liquid in the circulation system is gradually increased, the pressure p at the outlet end is gradually driven to the maximum, and the output power of the pump shaft 5 is gradually increased from zero to the maximum. The output speed of the pump shaft 5 is also gradually increased from zero to the speed of the pump body 1, so that the structure can fully realize the functions of clutch, brake and shifting, and integrates the three functions.
