At above-mentioned situation, the purpose of this utility model provide a kind of can be in very wide rotating speed, torque range work, and the pneumatic starting system of motor car engine simple in structure, easy to manufacture, energy-conservation wide accommodation.
For achieving the above object, the pneumatic starting system of a kind of motor car engine, it is connected with gas holder, pneumatic primer through tracheae, stop valve by air compressor, pneumatic primer comprises cylinder and gas motor, the gas motor comprises a main shaft, this main shaft is provided with one-way clutch gear and the fork with the engine flywheel gear engagement, and main shaft is in transmission connection by the piston rod in its fork and the cylinder.
For implementation structure optimization, its further step also has:
Gas holder connects a high pressure tank through tracheae, hand stop valve.
Cylinder is to select piston type spring reset cylinder for use.
The gas motor is to select the blade type expansion structure for use.
The utility model adopts the pressurized air that is produced by air compressor to drive gas motor and piston motion, make the interlock of one-way clutch gear and engine flywheel gear drive the technical solution of engine operation, having overcome pure electric motor needs generator and storage battery to drive and the electricity shortage phenomenon and the storage battery short defective in working life of appearance.
The beneficial effect that the utility model is produced compared to existing technology: (1) adopts the automobile of pneumatic starting system, the capacity of storage battery can be littler than electronic starting system, storage battery only need supply some low power consumers such as light, radio receiver, instrument, prolong the working life of storage battery, thereby reduce the regular maintenance cost of automobile; (2) pneumatic primer has startup rapidly, and pneumatic primer can rise at full speed when 1.5 change in rated power, and startability is better than motor driven starter; (3) pneumatic primer has overload protective function, is that rotating speed reduces or stall during overload, can not burn, and overload is separated decapacitation and resumed work immediately; (4) the gas motor can meet the demands by relatively low power, and easy to operate, easy to maintenance, and rate of fault is low, and no working environment restriction at high temperature, can both be worked under moist inflammable, as the to vibrate many dust rugged environment; (5) manufacturing process of pneumatic primer is simple, and low cost of manufacture, the key component gas motor technologies of pneumatic primer are now quite ripe, no special technique difficulty, and pneumatic primer is more in light weight than motor driven starter, and material does not need the copper of price is rather stiff yet.
The utility model is suitable for the car engine start device.
Below in conjunction with drawings and Examples the utility model is further described.
