Abstract
This utility model relates to the hydraulic clutch of a kind of hydrostatic transmission, is fixed with electric magnet on valve body, and described valve body has the first connection hydraulic fluid port, the second connection hydraulic fluid port and drain tap；Described first connects hydraulic fluid port is connected with the high-voltage oil cavity interface of hydrostatic transmission side, and second connects hydraulic fluid port is connected with the low pressure oil pocket interface of hydrostatic transmission opposite side；In work process, when electric magnet does not obtains from the signal of telecommunication of outside input, the oil circuit that the first connection hydraulic fluid port of valve body and second connects between hydraulic fluid port cuts off；Obtaining after the signal of telecommunication of outside input at electric magnet, the first connection hydraulic fluid port and second oil circuit connected between hydraulic fluid port of valve body communicate, and the first pressure connecting hydraulic fluid port and the second connection hydraulic fluid port gradually becomes identical, so that motor rotary speed is slack-off until stopping.This utility model simple in construction, install, safeguard, easy to use, the available signal of telecommunication realize to hydraulic clutch engagement with disengage, the long-range control of braking.
Description
Technical field
This utility model relates to a kind of clutch, and this utility model especially relates to the hydraulic clutch of a kind of hydrostatic transmission.
Background technology
The brake system of hydrostatic transmission has hydraulic brake system and mechanical brake system two kinds.Hydraulic clutch brake system utilizes automatically controlled mode to realize water brake function.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of available signal of telecommunication realizes hydraulic clutch engagement and disengagement, the hydraulic clutch of the hydrostatic transmission remotely controlled of braking.
The technical scheme provided according to this utility model, the hydraulic clutch of described hydrostatic transmission, including electric magnet and valve body, valve body is fixed with electric magnet, described valve body has the first connection hydraulic fluid port, the second connection hydraulic fluid port and drain tap；Described first connects hydraulic fluid port is connected with the high-voltage oil cavity interface of hydrostatic transmission side, and second connects hydraulic fluid port is connected with the low pressure oil pocket interface of hydrostatic transmission opposite side；In work process, when electric magnet does not obtains from the signal of telecommunication of outside input, the oil circuit that the first connection hydraulic fluid port of valve body and second connects between hydraulic fluid port cuts off；Obtaining after the signal of telecommunication of outside input at electric magnet, the first connection hydraulic fluid port and second oil circuit connected between hydraulic fluid port of valve body communicate, and the first pressure connecting hydraulic fluid port and the second connection hydraulic fluid port gradually becomes identical, so that motor rotary speed is slack-off until stopping.
This utility model has the advantage that
This utility model simple in construction, install, safeguard, easy to use, the available signal of telecommunication realize to hydraulic clutch engagement with disengage, the long-range control of braking；
This utility model easy to use and flexible, avoid hydrostatic transmission power waste, reduce use cost feature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the hydraulic schematic diagram of valve body in this utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
The hydraulic clutch of this hydrostatic transmission, including electric magnet 4 and valve body 5, is fixed with electric magnet 4 on valve body 5, and described valve body 5 has the first connection hydraulic fluid port 1, second and connects hydraulic fluid port 2 and drain tap 3；Described first connects hydraulic fluid port 1 is connected with the high-voltage oil cavity interface of hydrostatic transmission side, and second connects hydraulic fluid port 2 is connected with the low pressure oil pocket interface of hydrostatic transmission opposite side；In work process, when electric magnet 4 does not obtains from the signal of telecommunication of outside input, the oil circuit that the first connection hydraulic fluid port 1 of valve body 5 is connected between hydraulic fluid port 2 with second cuts off；Obtaining after the signal of telecommunication of outside input at electric magnet 4, the first connection hydraulic fluid port 1 of valve body 5 communicates with the second oil circuit being connected between hydraulic fluid port 2, and first connects hydraulic fluid port 1 gradually becomes identical with the second pressure being connected hydraulic fluid port 2, so that motor rotary speed is slack-off until stopping.
This utility model uses the high-voltage oil cavity driving revolution to communicate with low pressure oil pocket, it is achieved the braking to motor.
