Background technology
The trailer style of current heavy duty truck have independent trailer and superimposed trailer point, the trailer style of general truck is more specific, and be the wherein a kind of of above two kinds of trailer style, corresponding trailer braking protection valve gas source interface form with it trailer style matches.Connect source of the gas for convenience of trailer joint, independent trailer trailer joint is generally positioned at truck frame afterbody tail boom place, and superimposed trailer trailer joint is generally positioned at rear cabin.Can be there are above two kinds of trailer style in some extraordinary truck, both this truck can mate independent trailer and also can mate superimposed trailer.But braking gas source interface but cannot realize switching.
Summary of the invention
The utility model, in order to overcome the deficiency of above technology, provides the two trailer braking protection valve interface switching device of electric-controlled type that a kind of independent trailer and superimposed trailer gas source interface switch fast.
The utility model overcomes the technical scheme that its technical matters adopts:
The two trailer braking protection valve interface switching device of this electric-controlled type, comprise and be installed on front control gas joint on the portal frame of operator's compartment rear and front gas-charging connection, be installed on the rear gas-charging connection on vehicle frame tail boom and rear control gas joint, two-position four-way solenoid directional control valve and two band switches be arranged in operator's compartment, electromagnet on described two-position four-way solenoid directional control valve is connected to storage battery through two band switches, before described, control gas joint and front gas-charging connection are connected to two delivery ports of of two-position four-way solenoid directional control valve respectively by tracheae I and tracheae II, described rear gas-charging connection and rear control gas joint are connected to two delivery ports of the another one of two-position four-way solenoid directional control valve respectively by tracheae III and tracheae IV, two input ports of one of described two-position four-way solenoid directional control valve are connected to the control gas source interface of trailer control valve and the source of inflation gas interface of trailer control valve, two input ports of its another one are connected to the control gas source interface of trailer control valve and the source of inflation gas interface of trailer control valve.
Conveniently connect, also comprise two spiral tracheaes, one end of a described spiral tracheae is connected to front control gas joint, and its other end is connected to tracheae I, and one end of another spiral tracheae described is connected to and front gas-charging connection, and its other end is connected to tracheae II.
The beneficial effects of the utility model are: when electromagnet no power, and now, control gas joint and front gas-charging connection achieve and be connected with source of inflation gas interface with the control gas source interface of trailer control valve.When the solenoid is energized, two-position four-way solenoid directional control valve commutates, and achieves rear gas-charging connection and control gas joint to be afterwards connected with source of inflation gas interface with the control gas source interface of trailer control valve.Thus can conveniently adjust in operator's compartment complete hang trailer and rear gas-charging connection and rear control gas joint be connected after ventilation and semi-mounted trailer be connected with front control gas joint and front gas-charging connection after ventilation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, before 1. controlling gas joint 5. before trailer control valve 2. two-position four-way solenoid directional control valve 3. spiral tracheae 4., after gas-charging connection 6., after gas-charging connection 7., control gas joint 8. electromagnet 9. storage battery 10. 2 band switch 11. tracheae I 12. tracheae II 13. tracheae III 14. tracheaes IV.
Detailed description of the invention
Be described further below in conjunction with accompanying drawing 1 pair of the utility model.
The two trailer braking protection valve interface switching device of this electric-controlled type, comprise and be installed on front control gas joint 4 on the portal frame of operator's compartment rear and front gas-charging connection 5, be installed on the rear gas-charging connection 6 on vehicle frame tail boom and rear control gas joint 7, two-position four-way solenoid directional control valve 2 and two band switches 10 be arranged in operator's compartment, electromagnet 8 on two-position four-way solenoid directional control valve 2 is connected to storage battery 9 through two band switches 10, front control gas joint 4 and front gas-charging connection 5 are connected to two delivery ports of of two-position four-way solenoid directional control valve 2 respectively by tracheae I 11 and tracheae II 12, rear gas-charging connection 6 and rear control gas joint 7 are connected to two delivery ports of the another one of two-position four-way solenoid directional control valve 2 respectively by tracheae III 13 and tracheae IV 14, two input ports of one of two-position four-way solenoid directional control valve 2 are connected to the control gas source interface of trailer control valve 1 and the source of inflation gas interface of trailer control valve 1, two input ports of its another one are connected to the control gas source interface of trailer control valve 1 and the source of inflation gas interface of trailer control valve 1.By stirring two band switches 10, control the connection between storage battery 9 and electromagnet 8, thus control electromagnet 8 adhesive, realize the commutation of two-position four-way solenoid directional control valve 2, when electromagnet 8 no power, now, control gas joint 4 and front gas-charging connection 5 achieve and are connected with source of inflation gas interface with the control gas source interface of trailer control valve 1.When electromagnet 8 is energized, two-position four-way solenoid directional control valve 2 commutates, and achieves rear gas-charging connection 6 and control gas joint 7 to be afterwards connected with source of inflation gas interface with the control gas source interface of trailer control valve 1.Thus can conveniently adjust in operator's compartment complete hang trailer and rear gas-charging connection 6 and rear control gas joint 7 be connected after ventilation and semi-mounted trailer be connected with front control gas joint 4 and front gas-charging connection 5 after ventilation.
