Abstract
The invention discloses an air-cut brake combination valve. The air-cut brake combination valve comprises a working cylinder and a control valve, the control valve is provided with an operating handle, an air inlet and an air outlet, the air inlet and the air outlet are connected to the one end of a same conversion interface, the operating handle is connected with the conversion interface through an operating rod, the other end of the conversion interface is communicated with the interior of the working cylinder through a connecting air pipe, the working cylinder is internally provided with a piston and a spring in sequence from top to bottom, a connecting shaft is connected to the lower portion of the piston, one end of the connecting shaft extends out of the bottom of the working cylinder, and a connecting fork is connected to the end of the connecting shaft and connected with a pulling arm of a brake, a control valve is additionally installed on the outer side of the working cylinder, when an original braking system breaks down, the connecting fork of the working cylinder can tension or loosen the pulling arm of the break by inputting or outputting compressed air, mandatory braking of an automobile is achieved, and potential safety hazards are eliminated; the air-cut brake combination valve is simple in structure and extremely low in failure rate.
Description
Technical field
The present invention relates to one die brake combination valve.
Background technology
The parking braking of existing loader the most all uses mechanical operation, when driving,
The either component of this brakes is such as: air pump, pipeline, gas receiver and brake valve etc. break down,
Brake will be malfunctioning, and driver cannot find the fault of these parts in the very first time, easily
Have an accident, there is potential safety hazard.
Summary of the invention
Present invention aim to overcome that above-mentioned the deficiencies in the prior art, it is provided that a kind of easy and simple to handle,
It is not likely to produce fault, even if fault produces the air-break type braking group that still can carry out forced brake
Close valve.
The technical scheme is that one is died brake combination valve, including working cylinder, also wrap
Including control valve, described control valve is provided with operation handle, air inlet and air vent, described air inlet
Mouthful and air vent be connected on one end of same translation interface, operation handle by action bars with turn
Alias is connected, and by connecting, trachea and working cylinder are internal to be connected the other end of translation interface
Logical, from top to bottom it is sequentially provided with piston and spring in described working cylinder, is also associated with below piston
Connecting shaft, one end of connecting shaft is extended bottom working cylinder and connected connection fork, described connection
Fork is connected with the torque arm of brake.
Further, also include that control valve support, described control valve support are fixed on working cylinder,
Described control valve is fixed on control valve support.
Further, the top of described working cylinder is additionally provided with specific purpose tool interface, when automobile passes through
After the present invention realizes forced brake, this interface release brake force can be opened by specific purpose tool, just
Sued and laboured in vehicle and towed.
Further, it is additionally provided with Y between periphery and the inwall of described working cylinder of described piston
RunddichtringO.
Further, described working cylinder is fixed in car body by installing screw.
The invention has the beneficial effects as follows: the present invention installs a control valve additional in the outside of working cylinder,
During original braking system faults, by input or output squeezing gas, the connection fork of working cylinder can
Realize the tension to brake torque arm and unclamp, thus realizing the forced brake of automobile, eliminating peace
Full hidden danger, and present configuration is simple, the fault rate of itself is extremely low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below by embodiment, and combine accompanying drawing, technical scheme is made tool further
The explanation of body.
The brake combination valve as it is shown in figure 1, one is died, including working cylinder 1, also includes controlling
Valve 2, described control valve 2 is provided with operation handle 3, air inlet 4 and air vent 5, described
Air inlet 4 and air vent 5 are connected on one end of same translation interface 6, and operation handle 3 leads to
Crossing action bars to be connected with translation interface 6, the other end of translation interface 6 is by connecting trachea 7
It is connected with working cylinder 1 inside, in described working cylinder 1, is from top to bottom sequentially provided with piston 8
With spring 9, being also associated with connecting shaft 10 below piston 8, one end of connecting shaft 10 is extended
Bottom working cylinder 1 and connect and have connection fork 11, described connect fork 11 and the torque arm phase of brake
Connect.
Further, also include that control valve support 12, described control valve support 12 are fixed on work
Making on cylinder 1, described control valve 2 is fixed on control valve support 12.
Further, the top of described working cylinder 1 is additionally provided with specific purpose tool interface 13.
Further, it is additionally provided with between periphery and the inwall of described working cylinder 1 of described piston 8
Y-type seal ring 14.
Further, described working cylinder 1 is fixed in car body by installing screw 15.
When needing take-off the brake, the operation handle being manipulated by valve, open air inlet,
Making compressed air enter working cylinder by connecting trachea, promote descent of piston, piston promotes and connects
Axle also makes connection fork release brake torque arm release brake force；When brake or parking, by controlling
Operate the operation of handle on valve, cut off air inlet and open air vent and make control valve and be connected trachea
Connecting, the compressed gas in working cylinder is discharged by air vent, and piston drives under the action of the spring
Connecting shaft is up, and makes connection fork tension brake torque arm, plays the purpose of brake, parking.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention,
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made,
Should be included within the scope of the present invention.
