Abstract
The utility model relates to a controllable pre braking device for automobile trailer apparatus; the intake pipe of the controllable pre braking device is connected with the brake valve of the controllable pre braking device; a three-way connector is respectively communicated with the intake pipe, a trailer relay valve, and a two-position two-way electromagnetic pneumatic valve; the inlet and the outlet of the trailer relay valve are respectively connected with a trailer gas cylinder, a trailer brake branch pump, and a main gas cylinder; the inlet of the two-position two-way electromagnetic pneumatic valve is communicated with the trailer gas cylinder through a high-pressure pipe. The controllable coil of the two-position two-way electromagnetic pneumatic valve is connected with the circuit of a brake signal lamp through a converting switch; the driver can disconnect the converting switch to close the utility model. When a vehicle with the trailer of the utility model is break, the trailer with larger inertia arranged on the back of the main vehicle is break preceding the main vehicle, so the trailer can not hit the main vehicle, which ensures the driving safety.
Description
Technical field the utility model relates to a kind of brake device for car, the controlled brake equipment in advance of particularly a kind of auto trailer, and it can guarantee that trailer braking protection valve is prior to main car.
It is the brake equipment of power that the main car of the automobile of the existing band of background technology trailer and trailer all adopt pressurized air, and driver one steps on brake pedal, and pressurized air enters the brake cylinder of each wheel of main car and trailer simultaneously, implements braking simultaneously.But the quality of trailer (particularly heavily loaded trailer) is greater than main car, and during emergency braking, because the inertia of trailer is greater than main car, the trailer at rear portion is often answered back to fwd master car, causes the headstock laterodeviation, causes serious traffic accident.
The summary of the invention the purpose of this utility model provides the controlled brake equipment in advance of a kind of auto trailer, and when it can guarantee that the driver steps on brake pedal, the brake cylinder of trailer was implemented braking in advance than main car brake cylinder, and trailer braking protection valve is prior to main car.
The utility model is realized by following technical proposal: the controlled brake equipment in advance of a kind of auto trailer, its air inlet pipe is connected with brake activation valve, T-pipe joint is communicated with air inlet pipe, trailer relay valve and 2/2-way electromagnetism-gas-driving valve respectively, the import and export of trailer relay valve are connected with trailer storage tank, trailer braking protection valve wheel cylinder and main storage tank respectively, and the import of 2/2-way electromagnetism-gas-driving valve is communicated with the trailer storage tank by high-pressure pipe.The control coil of 2/2-way electromagnetism-gas-driving valve connects by change-over switch with the circuit of stop, tail and number plate light.
When the automobile brake of band trailer of the present utility model is housed, is positioned at the bigger trailer in main car rear portion, inertia and implements braking prior to main car, trailer can not answered back to main car, guarantees traffic safety.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the circuit diagram of stop, tail and number plate light and electromagnetism-gas-driving valve.
Specific embodiments embodiment is as shown in drawings: the controlled brake equipment in advance of a kind of auto trailer, its air inlet pipe (1) is connected with brake activation valve, T-pipe joint (2) is communicated with air inlet pipe (1), trailer relay valve (5) and 2/2-way electromagnetism-gas-driving valve (3) respectively, and the import and export of trailer relay valve (5) are connected with trailer storage tank (6), trailer braking protection valve wheel cylinder (7) and main storage tank (8) respectively.Main storage tank (8) constantly replenishes pressurized air by trailer relay valve (5) to trailer storage tank (6), remains specified air pressure.The control coil of 2/2-way electromagnetism-gas-driving valve (3) connects by change-over switch (9) with the circuit of stop, tail and number plate light.
In the existing brake system of car of calming the anger, when the driver had just stepped on brake pedal, what at first connect was the circuit of stop, tail and number plate light, just open brake activation valve subsequently, pressurized air enters each brake cylinder of main car and trailer simultaneously, implements braking simultaneously, and promptly the bright lamp of stop, tail and number plate light is prior to braking.If drive the automobile that band trailer of the present utility model is housed, and closed change-over switch (9), when the driver steps on brake pedal, what at first connect is the control coil of stop, tail and number plate light contactor (11) and 2/2-way electromagnetism-gas-driving valve (3), also open 2/2-way electromagnetism-gas-driving valve (3) in the time of the bright lamp of stop, tail and number plate light (10), pressurized air by trailer storage tank (6) through high-pressure pipe (4), 2/2-way electromagnetism-gas-driving valve (3), T-pipe joint (2), trailer relay valve (5) enters each brake cylinder (7) of trailer, trailer is implemented braking with the shortest gas transmission approach and time.The driver continues to step on brake pedal, just opens brake activation valve after trailer has begun braking, and pressurized air enters the brake cylinder of main car and trailer, and car load is implemented braking.Like this, be positioned at the bigger trailer in main car rear portion, inertia and implement braking prior to main car, trailer can not answered back to main car, guarantees traffic safety.The controlled brake equipment in advance of auto trailer can be controlled by the driver, if trailer is an empty wagons, does not need glancing impact in advance, and the driver can disconnect the change-over switch (9) that is positioned at operator's compartment, closes the utility model, recovers the system that original main car and trailer are braked simultaneously.
Claims (2)
1. the controlled brake equipment in advance of an auto trailer, comprise air inlet pipe, relay valve, storage tank and brake cylinder, it is characterized in that: its air inlet pipe (1) is connected with brake activation valve, T-pipe joint (2) is communicated with air inlet pipe (1), trailer relay valve (5) and 2/2-way electromagnetism-gas-driving valve (3) respectively, the import and export of trailer relay valve (5) are connected with trailer storage tank (6), trailer braking protection valve wheel cylinder (7) and main storage tank (8) respectively, and the import of 2/2-way electromagnetism-gas-driving valve (3) is communicated with trailer storage tank (6) by high-pressure pipe (4).
2. the controlled brake equipment in advance of a kind of auto trailer according to claim 1, it is characterized in that: the control coil of 2/2-way electromagnetism-gas-driving valve (3) connects with the circuit of stop, tail and number plate light by change-over switch (9).
