With long lifespan, good reliability.
In order to achieve the above object, the technical scheme of present invention offer is：Including upper shell, the upper shell passes through breechblock
It is connected with lower house, piston type cam control gear, the work is installed in the space that the upper shell and lower house are formed
Plug cam control gear includes plunger shaft, and guide piston is provided with the plunger shaft, and the guide piston left end passes through six
Corner bolt and lower house are movably connected, and the guide piston right-hand member is connected with control piston, and the control piston and piston type are convex
Wheel is connected, and the piston type cam is connected by pressure spring with short axle, with valve core bar assembly at the top of the piston type cam
It is in contact, the short axle is connected by regulator bolts with lower house, the piston type cam control gear also includes mandrel chamber, institute
State and mandrel is installed in mandrel chamber, the mandrel right-hand member is connected by pressure control spring with lower house, the plunger shaft and core
Axocoel pipeline is connected.
The pressure spring middle part is provided with pressure spring positioning seat.
The mandrel left end is provided with hole back-up ring.
The hex bolts and lower house junction are provided with sealing nut.
Rubber air air bag connector and piston type adjusting control valve connector are further opened with the lower house.
The beneficial effects of the invention are as follows：Sense carries sensitive, long service life, good reliability.

Fig. 2 is three-dimensional structure diagram of the invention.
Specific embodiment
Embodiment 1
As shown in Figure 1, 2, a kind of piston type cam adjustment control automatic load sensing valve of automobile braking force, including upper shell 1, it is described on
Housing 1 is connected by breechblock 2 with lower house 3, and it is convex to be provided with piston type in the space that the upper shell 1 and lower house 3 are formed
Wheel control device, the piston type cam control gear includes being provided with guide piston 4 in plunger shaft 16, the plunger shaft 16,
The left end of the guide piston 4 is movably connected by hex bolts 5 and lower house 3, the right-hand member of the guide piston 4 and control piston 6
It is connected, the control piston 6 is connected with piston type cam 7, and the piston type cam 7 is connected by pressure spring 8 with short axle 9,
The top of the piston type cam 7 and valve core bar assembly 10 are in contact, and the short axle 9 passes through regulator bolts 11 and the phase of lower house 3
Even, the piston type cam control gear also includes being provided with mandrel 12, the mandrel 12 in mandrel chamber 17, the mandrel chamber 17
Right-hand member is connected by pressure control spring 13 with lower house 3, and the plunger shaft 16 is connected with the pipeline of mandrel chamber 17.
The middle part of the pressure spring 8 is provided with pressure spring positioning seat 14.
The left end of the mandrel 12 is provided with hole back-up ring 15.
The hex bolts 5 and the junction of lower house 3 are provided with sealing nut 18.
Rubber air air bag connector 19 and piston type adjusting control valve connector 20 are further opened with the lower house 3.
The piston type cam adjustment automatic load sensing valve of control automobile braking force is arranged on vehicle frame, rubber air air bag connector
19 and piston type adjusting control valve connector 20 adjusted with the interface and piston type of rubber air air bag of the design in vehicle bridge respectively
Section control valve interface connection, under no-load condition, rubber air air bag and control the pressure between valve be minimum, valve core bar is total
Extreme lower position is in into 10, the rubber air gasbag pressure increase if lorry loading, while rubber air air bag connector 19
Pressure with piston type adjusting control valve connector 20 also increases therewith, and air pressure acts on guiding by passage into plunger shaft 16
4 pushed upwards piston type cam of piston 7 drives valve core bar assembly 10 to be moved from idle position to fully loaded locality, by rubber
The sensing of glue air bag pressure, in the presence of pressure spring 8, makes valve core bar assembly 10 move to and load feelings at that time
The corresponding position of condition.
