Abstract
The utility model relates to an auxiliary air supply device of compressed air for the brake system of the vehicle. The utility model can supplement air to the brake system and keep the brake system of semi-trailer always in normal operating conditions without changing the transmission structure of the vehicle or affecting the running operation, thus the influence on normal running of the vehicle caused by deficiency under the pressure of the brake system can be avoided. The utility model can guarantee the safe operation of the vehicle, at the same time, reduce the unnecessary fuel consumption caused by the insufficient pressure of the brake system, save fuel and reduce the emission of exhaust air.
Description
Technical field
The utility model relates to that brake system of car is compressed-air actuated to be provided, and specifically relates to the pressurized air helping air supply device of brake system of car.
Background technology
The train-type vehicle of being made up of automobile and trailer in the present road transport, the train-type vehicle that semi-trailer towing vehicle and superimposed trailer are formed has accounted for the significant proportion of road travel vehicle.The brake system of these train-type vehicles is pneumatically work.Therefore how braking effect is that the ground of strict demand is arranged to compressed-air actuated pressure and the reserves that guarantee its reliable operation.Guarantee the required pressurized air of brake system of car normal operation at present, all provide by the equipped air compressor of automotive engine direct drive.Because the pressurized air that the equipped air compressor of automotive engine provides is limited, and train-type vehicle braking procedure gas consumption is big.So can't guarantee the cruising of vehicle frequent glancing impact vehicle on ramp or complicated road.The running engine that needs often car to be stopped replenishes pressurized air to brake system.The volumetric quantity of the compressed-air energy storage container of train-type vehicle brake system is big in addition, when air pressure is low when needing inflation to improve pressure, equally also will replenish pressurized air with the long period running engine, has not only wasted fuel but also unfavorable environmental protection.
Technology contents
The utility model just provides a kind of pressurized air helping air supply device of brake system of car, remedies the pressurized air defect of insufficient that automotive engine provides, and guarantees that the pressurized air of train-type vehicle brake system is in effective deposit state all the time.
The technical solution of the utility model is under the prerequisite that does not change the former pressurized air gas-supplying structure of automobile, from the power taking output interface junction of change speed gear box 1, power takeoff 2 to be installed.Power takeoff 2 obtains torque from the power taking interface of change speed gear box.The mouth of power takeoff 2 links by coupler 3 and magnetic clutch 4, and the mouth of magnetic clutch 4 flows to air compressor 6 by coupler 5 with torque.
The pressurized air that air compressor 6 runnings produce is delivered to energy storage gas tank 8 by supply air line 7.Be installed in the air pressure switch 9 on the energy storage gas tank 8, according to brake system ground pressure situation, control magnetic clutch 4.By the combination of magnetic clutch 4 or the conversion of released state, control air compressor 6.
The utility model distinguishing feature is to replenish air feed to this system timely and effectively when brake system pressure is not enough, and the train-type vehicle brake system is under the normal operating conditions all the time.Avoid because of the not enough cruising that influences vehicle of brake system pressure.Reduce owing to brake system pressure is not enough producing unnecessary consumption of fuel simultaneously, saving fuel reduces discharging.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: the 1st, be connected the change speed gear box on the driving engine, the 2nd, power takeoff, 3 and 5 is coupler, the 4th, magnetic clutch, the 6th, air compressor.The 7th, supply air line.The 8th, energy storage gas tank, the 9th, air pressure switch.
The specific embodiment
With example the utility model is described further in conjunction with the accompanying drawings.
Power takeoff is by the power taking output interface position that is bolted to vehicle gear box in the accompanying drawing, and the power takeoff gear is meshed with the power output gear at change speed gear box power taking output interface place.
When the air pressure of brake system is lower than 0.6Mpa, be installed in the air pressure switch 9 on the energy storage gas tank 8, will be in connected state, connect the power supply of magnetic clutch 4.Under the electromagnetic force effect, the mechanical driving part of magnetic clutch 4 is in bonding state, makes power takeoff 2 obtain torque, and torque is by coupler 3, and magnetic clutch 4 and coupler 5 are transferred to air compressor 6.Drive air compressor 6 runnings.Provide pressurized air to motor vehicle braking system.
When the air pressure of brake system reaches 0.6Mpa, be installed in the air pressure switch 9 on the energy storage gas tank 8, will be in off-state.This moment, the power supply of magnetic clutch 4 was cut off.Make the magnetic clutch mechanical driving part be in released state.Air compressor 6 shuts down.The motor vehicle braking system pressurized air is still continued to provide by the equipped air compressor of driving engine.
Claims (2)
- The pressurized air helping air supply device of 1 one kinds of brake system of car, comprise air compressor, air delivering pipeline and energy storage gas tank, it is characterized in that described air compressor is connected with magnetic clutch by coupler, the magnetic clutch other end is installed in the mouth of power takeoff by coupler.
- The 2 pressurized air helping air supply devices by the described brake system of car of claim 1 is characterized in that, power takeoff is installed in the power taking output junction of automobile gearbox, obtains torque from change speed gear box.
