The truck with the trailer has synchronous direct braking system of the main cart and the trailer, and retainning the former expired braking function of the trailer; thus the air braking system of the truck can reduce tyre wearing and raise safe system of driving.
Description
The utility model belongs to truck compression air brake technical field.
The Pneumatic braking system of truck is generally all considered the brake of trailer.The brake modes of dying is adopted in common trailer brake, for example east wind 140 and liberation 140.The shortcoming of this brake modes is only when emergency braking, and tractor truck could be synchronous with towed vehicle, and when tractor truck adopts the control brake, the trailer band-type brake be not too early, dead excessively, be exactly slow, bring difficulty to driver behavior, cause parts to damage again easily.
A kind of improved trailer straight dual-purpose brake system of breaking is arranged at present, adopt the brake of a brake activation valve direct control of tractor truck trailer.This improvement influences the braking force of tractor truck, and is relatively poor to the direct braking effect of trailer, can not obtain promoting.
The purpose of this utility model is to provide a kind of improved truck Pneumatic braking system, makes towed vehicle obtain good direct control of braking, keep former its braking function of dying simultaneously, and the braking function of tractor truck self is unaffected.
Task of the present utility model is achieved in that
Increase the direct control of braking subsystem of trailer in the truck Pneumatic braking system, this control subsystem comprises:
(1.1), in the Pneumatic braking system of main car (tractor truck), increase by one by air tank 5, the control system that brake activation valve 11 and pipeline are formed, the admission port of air tank 5 is connected with main air reservoir (wet air tank) 2 through check valve 9, air extractor duct connects the inlet chamber of brake activation valve 11 by pipeline, the epitrochoidal chamber of brake activation valve 11 connects the direct brake pipe 18 of trailer, the joystick 19 of brake activation valve 11 joins through connecting rod 20 and brake pedal 21
(1.2), in the brake system of trailer, increase two-way valve 24 and rapid release valve 25, an inlet chamber of two-way valve 24 connects the epitrochoidal chamber of original automatic valve 26, another inlet chamber connects the direct brake pipe 27 of main car, the epitrochoidal chamber of two-way valve 24 connects the inlet chamber of rapid release valve 25, and the epitrochoidal chamber of rapid release valve 25 connects trailer front and back wheel braking device.
After former brake system done above-mentioned improvement, newly-increased automatic valve 11 was realized synchro control with the joystick 19 and 22 of former brake activation valve 10 through connecting rod 20, and during main car brake, trailer obtains synchronously directly brake operation through newly-increased subsystem.And being provided with of the two-way valve 24 on the trailer kept the original brake function of dying of trailer, and 25 of rapid release valves make the rapid emptying of pipeline return-air, guarantees the sensitivity of direct brake operation.
For improving the safety of truck Pneumatic braking system, in main car brake system, also increase an auto brake system of forming by air tank, automatic valve and two-way valve etc., so that when the air pressure of brake system is lower than authorized pressure, automobile is in the autobrake state.
Below in conjunction with drawings and Examples, the utility model is elaborated.
Fig. 1 improves the main car air braking system scheme drawing in back.
Fig. 2 improves trailer brake system scheme drawing.
System in Fig. 1 frame of broken lines is the newly-increased direct brake system of trailer of main car, air tank 5 is communicated with main air reservoir (wet air tank) 2 through check valve 9, its outlet side connects brake activation valve 11 through tracheae, the epitrochoidal chamber of brake activation valve 11 connects a newly-increased direct brake pipe 18 of trailer, and the joystick 19 of brake activation valve 11 is connected with braking footrest 21 through connecting rod 20.Adjust the brake time of main car and trailer during installation by connecting rod 20, generally make trailer more a little earlier than main car.
Also set up air tank 6 and automatic valve 16 among Fig. 1, as the low-voltage safety control setup, automatic valve 16 pressure sensing interfaces connect the air tank 3 or 4 of former brake system, to obtain the operation pressure information of system, the epitrochoidal chamber of automatic valve 16 connects main car front and back wheel brake repair room (not drawing among the figure) respectively through two-way valve 12,13 and rapid release valve 14,15.When a pressure signal from air tank 3 or 4 is lower than specified value, as 4.5kg/cm
2The time, automatic valve 16 valves start, and air tank 6 is communicated with two-way valve 12,13, and main car is placed braking state, guarantee safety.
Remainder among Fig. 1, as air pump 1, check valve 17,7,8, brake activation valve 10 and brake activation valve joystick 22, trailer often have tracheae 23 grades to be former braking system part, and connecting with trailer has tracheae 23 to be connected with corresponding with the trailer respectively pipeline of direct brake pipe 18 that increases newly often.
System in Fig. 2 frame of broken lines is the brake system supporting brake control system newly-increased with main car.Directly brake pipe 27 is connected with the pipeline 18 of main car, connect trailer front and back wheel brake repair room (not shown) through two-way valve 24, rapid release valve 25, and the discharge chamber of original automatic valve 26 connects another inlet chamber of two-way valve 24.There often have tracheae 28 to connect main car tracheae 23 to be constant.When main car was carried out control brake, directly brake system work made main car or trailer synchronous braking like this; When main car emergency braking or the disengaging of trailer brake system, the original brake system work as usual of dying of trailer.The setting of rapid release valve 25 is that the rapid emptying of the gas in the brake repair room pipeline is with the sensitivity that guarantees that brake is handled for when directly brake is handled.Part 29 is the former air tank of establishing.
The utility model adopts the standard brake part that former truck Pneumatic braking system is made local improvement, cost is low, repacking is convenient, in-use performance satisfies relevant requirements and can make trailer obtain direct brake function, realize main car and trailer synchronous brake, reduce Tyte Wear, and improve the driving safety coefficient that band drags truck.
