Because the heavy automobile clutch that the utility model adopts brand new is with automatically controlled pneumatic control valve and electric feedback technique, therefore compared with prior art, not only simple in structure small and exquisite, control is simple, accurate, and cheap, and be convenient to be integrated into beneficial effects such as electric control mechanical type automatic speed variator system.
Description of drawings
Fig. 1 is the structure cross-sectional schematic of the utility model heavy automobile clutch with automatically controlled pneumatic control valve;
Fig. 2 is structure and the control schematic representation of the utility model heavy automobile clutch with automatically controlled pneumatic manoeuvring system.
Embodiment
The utility model is described further the utility model for the ease of more being expressly understood below in conjunction with accompanying drawing.
As shown in Figure 1, heavy automobile clutch described in the utility model comprises push buttonvalve 110 and the proportion electro-magnet 120 that uses as the Torque Control parts with automatically controlled pneumatic control valve 100.Described proportion electro-magnet 120 is connected with the valve rod 111 of described push buttonvalve 110, such as connect by pin, be threaded, welding or mighty bond are bonding etc. any can be with the two compact and firm ways of connecting.Described proportion electro-magnet 120 can receive the command signal from the controller of electric control clutch, and under the control of this command signal, move, and then move with the suction port 113 of controlling described push buttonvalve 110 and the closure or openness of relief opening 112 along its axial direction by driving described valve rod 111.Because an end relative with valve rod 111 of described push buttonvalve 110 is provided with the opening 114 that links with the gas receiver (not shown), and described suction port 113 links with the power-assisted cylinder 300 of electric control clutch, thereby the moving back and forth under proportion electro-magnet 120 control by valve rod 111, just can realize the air assisted of heavy automobile electric control clutch is controlled.According to the needs that the production and the cost of reality are considered, above-mentioned Torque Control parts can also adopt torque motor.
Adopt the automatically controlled pneumatic control valve of heavy automobile clutch of said structure, compare with the existing electric controlled pneumatic control valve that is used for the integrated design of employing in other technologies field in the prior art, such as proportional pressure-reducing valve and high frequency valve etc., control valve of the present utility model has structure and control is simple, low production cost, and can be integrated into the first-class advantage of electric control mechanical type automatic speed variator more easily.
Please with further reference to shown in Figure 2, the automatically controlled pneumatic manoeuvring system of heavy automobile clutch described in the utility model comprises clutch pedal displacement transducer 400, clutch displacement sensor 500, power-assisted cylinder 300, controller 600 and electric controlled pneumatic control valve 100.Preferably, described controller 600 adopts various single-chip microcomputers, perhaps selects for use DSP (DSP digital signal processor) or other embedded control system etc. also passable, and is as long as it is small and exquisite to satisfy the needs and the compact structure of control, with low cost.Wherein, as previously described, described electric controlled pneumatic control valve 100 comprises proportion electro-magnet 120 and the push buttonvalve 110 that uses as the Torque Control parts again, the valve rod 111 of described proportion electro-magnet 120 and described push buttonvalve 110 is connected by pin, perhaps by be threaded, welding or mighty bond are bonding etc. any can be with the two compact and firmly ways of connecting be connected.Controller 600 is electrically connected with proportion electro-magnet 120 on this electric controlled pneumatic control valve 100, described clutch pedal displacement transducer 400 and clutch displacement sensor 500 are electrically connected with described controller 600 respectively, realizing the collection of 600 pairs of clutch pedal displacement signals of controller and clutch displacement signal, 113 pneumatic connections of suction port of described power-assisted cylinder 300 and described push buttonvalve 110.An end relative with valve rod 111 of described push buttonvalve 110 is provided with the opening 114 that links with the gas receiver (not shown).Described proportion electro-magnet 120 is under the control of the command signal of the controller 600 of electric control clutch, and the suction port 113 by driving the push buttonvalve 110 that described valve rod 111 motions link with the power-assisted cylinder 300 of control and described electric control clutch and the closure or openness of relief opening 112 are realized the air assisted control to heavy automobile electric control clutch.
Because above-mentioned heavy automobile clutch adopts electric feedback with automatically controlled pneumatic manoeuvring system, compare with the structure of realization machine feedback such as available technology adopting stepper motor and gear rack, it is more simple, accurate to have structure and control, shape is more compact small and exquisite, manufacture cost is therefore more cheap, and can be integrated into the first-class beneficial effect of electric control mechanical type automatic speed variator more easily.
The utility model heavy automobile clutch with the working principle and the process of automatically controlled pneumatic control valve and ecp control system is:
The signal of clutch pedal displacement transducer 400 acquisition instructions positions, clutch displacement sensor 500 is gathered the signal of the physical location of clutch simultaneously.Controller 600 calculates command signal according to the difference of the signal of the signal of gathering the location of instruction of coming and clutch physical location, and this command signal is sent to the action of proportion electro-magnet 120 with control knob valve 110.
Particularly, when the driver depresses pedal, when the location of instruction of clutch pedal is bigger than the physical location of clutch, the difference of controller 600 signal of the two according to this calculates command signal, this command signal is sent to proportion electro-magnet 120, this proportion electro-magnet 120 presses the valve rod 111 of push buttonvalve 110 downwards, this moment, suction port 113 was opened, relief opening 112 is closed, high-pressure air in the gas receiver (not shown) enters power-assisted cylinder 300 via opening 114 and suction port 113, thereby promotes clutch separation; When clutch pedal rests on certain position, continuous separation along with clutch, the difference of the location of instruction and physical location reduces, the also value of command signal that controller 600 sends to proportion electro-magnet 120 is more and more littler, therefore proportion electro-magnet 120 pressure that imposes on the valve rod of push buttonvalve 110 also correspondingly reduces, like this, in case this pressure is reduced to below the specific value, then overcome above-mentioned pressure under the elastic force effect of the spring 115 that valve rod 111 will be thereunder and move up, when the location of instruction equates with physical location, valve rod 111 moves on to the position that suction port 113 and relief opening 112 are closed on just in time, this moment, elastic force and the proportion electro-magnet 120 downward pressure of the spring 115 received of valve rod 111 equated that then clutch remains on this disengaging configuration; At last, when driver's release the clutch pedal, the location of instruction is less than physical location, the command signal that controller 600 is exported to proportion electro-magnet 120 further reduces until being close to zero, the pressure that this moment, proportion electro-magnet 120 acted on the valve rod 110 acts on restoring force on the valve rod 110 less than spring 115, move on on the valve rod 110 that suction port 113 is closed and position that relief opening 112 is opened, then clutch.
Described push buttonvalve can adopt the push buttonvalve in the traditional mechanical type heavy automobile clutch control gear that now can buy on the market, so its structure just no longer describes in detail at this.
