Abstract
The utility model relates to a delayed braking relieving device for preventing a motor vehicle from sliding back when the motor vehicle starts on a ramp. The delayed braking relieving device is composed of a first sensing part, a second sensing part, a control circuit and an electromagnetic valve, wherein the first sensing part is connected in series with a gradient switch, a clutch switch, a switch for a braking signal lamp and a switch for a speedometer; the second sensing part is connected in series with a vibration sensor and a switch for an accelerating pedal. When the vehicle runs on a road surface with certain gradient in the situation of traffic jam, after a driver brakes the vehicle by a foot, the first sensing part is switched on, a normally open magnetic valve arranged in a brake pipe is closed by the control circuit, and high-pressure air in a brake chamber is stopped exhausting. When the driver starts the vehicle again, a clutch is engaged with a transmission system to generate enough dynamic force to start the vehicle, the second sensing part responses, the magnetic valve is switched on by the control circuit, and brake is relieved.

Description
Affiliated technical field
The utility model relates to a kind of braking force control system, especially a kind of device that postpones to brake releasing.
Background technology
When the automobile of non-automatic ripple is started to walk on the slope in order to prevent down slide, often use hand braking assistance, when promptly after automobile is braked on the slope, starting to walk again, the left foot of the person of controlling is gently lifted pedal of clutch, and the right crus of diaphragm step on the accelerator improves engine power, must vacate a hand simultaneously to remove hand braking, increased the complexity of operation like this, and probably because the two mismate of releasing of the joint of power-transfer clutch and braking has aggravated the damage of power-transfer clutch and other part.
Summary of the invention
When the utility model is intended to start to walk again, reduce the complexity of the person of controlling operation on the ramp, and reduce relevant machine members after manually the car on slope is braked.
The technical scheme that its technical matters that solves the utility model adopts is: whole device is made up of first transducing part, second transducing part, control circuit and electromagnetic valve.When starting to walk again after sensing is partly mainly braked on the ramp according to automobile, the action of power-transfer clutch and brake system and setting.Present power-transfer clutch particularly large-tonnage automobile adopts hydraulic actuated formula power-transfer clutch more, when chaufeur let slip the clutch cut-off clutch, oil pressure in the oil pipe of clutch hydraulic operation can change with the variation of diaphragm spring in the power-transfer clutch or coil spring amount of compression, when power-transfer clutch separates fully, oil pressure in the oil pipe can reach certain pressure values, the pressure switch that installs similar braking signal switch on pipeline additional is as clutch switch, this moment, clutch switch was connected, and showed that chaufeur implemented the action of complete cut-off clutch.
Chaufeur is implemented glancing impact, and the braking signal switch in the brake piping is connected.
When automobile is to be on the road surface that certain slope is arranged, and headstock is on the slope time, gradient switch connection.
When the speed of a motor vehicle was zero, the pointer of average speed indicator returned zero, and pointer contacts with the electrode at calibrated disc zero-bit place, and pointer is connected with lead itself also as electrode, then the average speed indicator switch connection.
Two of lead is connected on the control circuit, the clutch switch of having connected altogether in the lead, braking signal switch, gradient switch and average speed indicator switch.
When automobile goes up a slope on the ramp, gradient switch on this moment, as situations such as red lights, need to carry out stopping-down, chaufeur left foot let slip the clutch, right crus of diaphragm is stepped on brake pedal, then clutch switch, braking signal switch is all connected, if this moment, automobile stopped, the average speed indicator switch connection, then lead is connected, and has triggered control circuit, for compressed air brake system, control circuit makes the closed electromagnetic valve that is arranged in pipeline between brake activation valve and compressed air brake cylinder, though this moment the chaufeur loosen the brake because the high pressure gas in the compressed air brake cylinder can't be discharged, braking is not removed, and automobile can not slip.And when chaufeur will be started to walk, only need left foot gently to lift power-transfer clutch, and right crus of diaphragm is throttle a little, and then this moment, power-transfer clutch cognition produced vibration owing to the frictional engagement of clutch driven disc and flywheel and platen, and the frequency of vibration can change with the degree of tightness of clutch engagement.On case of transmission, adorn vibration sensor near power-transfer clutch, when even clutch engagement arrives brake off, when automobile can not take place to slip yet, the vibration of power-transfer clutch can reach certain frequency, and vibration sensor is passed to control circuit with signal, has made the acceleration pedal switch connection when adding just now the chaufeur bend the throttle, so control circuit just makes the electromagnetic valve in the brake piping open, high pressure gas in the compressed air brake cylinder is discharged, and then braking is removed, and automobile just can have been started to walk fully.Also can be without vibration sensor, and only need know that the chaufeur left foot lifted power-transfer clutch, right crus of diaphragm is bend the throttle, means that chaufeur will make vehicle starting, and control circuit just makes the electromagnetic valve in the brake piping open, thereby makes brake off.Be to realize like this on the device, setting pressure or displacement pickup in the oil pipe of the power-transfer clutch that adopts the fluid pressure type steering unit, when chaufeur is gently lifted pedal of clutch, oil pressure in the oil pipe changes, then the resistance that inserts in the lead in pressure or the displacement pickup changes thereupon, and the electric current that causes lead to flow to control circuit changes, and adds the joint of acceleration pedal switch, control circuit just makes the electromagnetic valve in the brake piping open, thereby braking is removed.
If chaufeur is not being thought to start to walk after the braking on the ramp again, but think long-time parking, as long as pull-up manual brake control lever, original braking during standstill works, hand brake switch disconnects during the pull-up manual brake control lever, hand brake switch is the main supply switch of control circuit, and then this device temporarily no longer works, and the electromagnetic valve in the brake piping is opened.
The beneficial effects of the utility model are: the releasing of braking and the binding energy of power-transfer clutch were automatically coordinated when the car of manual ripple was started to walk on the ramp, alleviate the driver's operation complexity, reduce the correlated parts wearing and tearing, prevent that vehicle from taking place to fall to slip, increase the ageing of uphill starting.
