Abstract
The utility model discloses a double-way doing work air compressor apparatus suitable for using on the passenger cars and trucks of DongFeng and JieFang., which is composed of a push rod (18) which is matched on a crank shaft (1) connected with a piston (10) by a lower cylinder cover (16). When the push rod (18) drives the piston (10) to move top and bottom under driven by the crank shaft (1), air goes into a long air inlet (11) of the middle part of the piston (10) from an air inlet hole (12) of the middle part of a cylinder body (4), then passes through air inlet valves (7), (13) of the top and bottom surfaces of the piston (10) and is exhausted from exhausting valves (8), (14) of top and bottom cylinder covers (9) (16), so as to realize the paths of going into and exhausting air. Machine oil goes into an annular oil groove (6) of the middle part of the piston (10) from an oil feeding hole (5) of the middle part of the cylinder body (4), flows back to a crank case (3) from an oil hole (19) of the push rod and flows out through an oil return hole (24), so as to realize the paths of going into and returning oil.
Description
The present invention relates to a kind of improved air compressor, particularly a kind of novel two-way work doing air Compressor unit is applicable on the big-and-middle-sized passenger-cargo carriage of liberation, Dongfeng series.
Existing air compressor is owing to be subjected to the restriction of connecting rod, bent axle, piston mechanism, can only be when piston stroking upward unidirectional acting pressurized air, then can not produce pressurized air during descent of piston and flog a dead horse.
Task of the present invention is: break through the restriction of existing air compressor crank, connecting rod, piston mechanism, and change intake and exhaust, lubricating system, and provide a kind of novel two-way work doing air Compressor unit, its objective is the raising charging efficiency, produce enough operating air pressures, to satisfy the driving needs of automobile under different road conditions.
The present invention by bent axle, push rod, piston, cylinder body, cylinder cap, intake and exhaust valve, copper sheathing and seal ring, needle bearing or sliding bearing, crankcase and front and rear covers, bottom, belt pulley are formed up and down, adopt two kinds of air inlets, lubricating system.
Accompanying drawing of the present invention is by a kind of intake and exhaust, and lubricating system is drawn.
The invention is further described below with reference to accompanying drawing.
Fig. 1 is the sectional view of a kind of concrete structure of the present invention.
Fig. 2 is bent axle on Fig. 1, needle bearing, the push rod sectional drawing along A-A.
Fig. 3 is a schematic diagram of the present invention.
The bent axle of three sections compositions (1) is installed on the ball bearing (21) at crankcase (3) two ends.The protruding arm of bent axle (1) is dismantled and assembled be convenient to install needle bearing (20) push rod up and down steel disc (22) tie tipping with gong and fit on needle bearing (20) cylindrical.Push rod shaft (18) by with following cylinder cap (16) that crankcase (3) is connected on copper sheathing (17), seal ring (15) enter cylinder body (4) and piston (10) down end face gong line be connected, push rod shaft oilhole (19) is communicated with the lip-deep annular oil groove of piston (10) (6).When belt pulley (25) drives bent axle (1) rotation, also drive push rod shaft simultaneously and promote the vertical motion up and down of piston (10) do.When piston (10) when lower dead center is up, because piston (10) air intake valve (7) (13) on the end face up and down communicates with microscler suction port (11) in the middle part of the piston (10), and under the effect of inertial force and degree of vacuum, intake valve (7) (13) interlock is also closed rapidly and is opened about making.Air enters the supermedial microscler suction port of piston (10) (11) by the inlet hole (12) in the middle part of the cylinder body (4) and enters cylinder body lower compression chamber from the air intake valve (13) on the following end face of piston (10), at this moment the air intake valve (7) on the last end face of piston (10) is closed, and the air of compression enters gas receiver from the drain tap (14) on the following cylinder cap (16).So intake and exhaust so up and down are can two-way work doing pressurized air.Also can adopt and be installed into air valve on the cylinder cap (9) (16) up and down, make air directly enter up and down pressing chamber of cylinder body, then the inlet hole (12) at cylinder body (4) middle part and the microscler suction port (11) in the middle part of the piston (10) and piston (10) up and down the air intake valve of end face (7) (13) just shouldn't.When piston moves intake and exhaust up and down, enter the annular oil groove (6) at piston (10) middle part from the next oil-feed eye (5) of machine oil of motor main oil gallery through cylinder body (4) middle part, flow back to crankcase (3) from push rod shaft oilhole (19), in the time of needle bearing (20) on ball bearing (21), push rod (18) (22) and the bent axle (1) in the lubricated crankcase on the two ends, spill port (24) the return engine crankcase of part machine oil from the crankcase cover.Also can adopt, machine oil enters without the oil-feed eye (5) on the cylinder body (4), and directly by the machine oil in the crankcase (3), the inertial force that produces when push rod moves up and down forces small amount of engine oil only to enter the surperficial supermedial annular oil groove of piston (10) (6) from push rod shaft oilhole (19), thereby the rubbing surface between lube pistons and cylinder body
The invention process result: its aeration quantity is two times of EQ140 single cylinder air compressor, and lubricated good, does not go up machine oil, and temperature is normal.Its surface: exceed 3 centimetres except that having increased a following cylinder cap (16), the same substantially with EQ140 single cylinder air compressor.Its structural member: except bent axle (1), push rod (18) (22), piston (10), cylinder body (4), following cylinder cap (16) can not exchange with EQ140 single cylinder air compressor, other structural member such as crankcase (3), front and rear covers (2) (23), bottom (24), upper cylinder cover (9), belt pulley (25) can exchange general with EQ140 single cylinder air compressor.Be characterized in: 1, simple in structure, maintenance and manufacturing are convenient in stable performance.2, technology is uncomplicated, the production cost is low.3, have certain interchangeability, have the realistic meaning of Development and Production.
The present invention has considered three kinds of reliable unloading methods; When guaranteeing driving, have under enough operating air pressures, can make air compressor idle running or stall, to prolong its working life and to reduce power consumpiton.Therefore item is not in claim, so slightly.
