Description
Technical field
The present invention relates to a kind of drive hub, particularly a kind of Motor Vehicle two-way controllable overrunning slides drive hub.
Background technique
Before the application, I have applied for that but a name is called the utility model patent of the manually-operated clutch (application number is 02201786.0) of fuel-economizing, it comprises actuation gear, guide bearing, inner core, driving wheel hub, pressing plate, from movable friction plate, active friction plate, wheel hub, spring and screw, it has advantage such as operate steadily, the life-span is long, oil-saving effect is good.But its deficiency is: can only use on the double clutch motorcycle.Existing drive hub mainly is made of (is example with the straddle type motorcycle) driving sprocket wheel, screw, driving wheel disc, buffer stopper, oil sealing, bearing, brake block, wheel hub and hub cap.
Summary of the invention
The objective of the invention is to propose a kind of both having can be used on the straddle type motorcycle, can be used on again on the pedal motorcycle, can also be used on compact car and other motor vehicle, and have a kind of Motor Vehicle drive hub of good fuel-economizing and Security.
Technological scheme of the present invention is as follows:
A kind of Motor Vehicle two-way controllable overrunning slides drive hub, and it mainly comprises driving sprocket wheel, live axle, wheel hub, guide bearing (being overrunning clutch), bearing and multi-disc wet clutch.It is characterized in that: the tongue and groove that on the interior circle of wheel hub, is provided with a cast boss and outer clutch drum shape, one bearing is loaded in the boss, end near boss is installed with an above guide bearing, this guide bearing is: include ball bearing and support wedge block type or roller type guide bearing, live axle is stuck in the wheel hub by the center circle borehole jack of guide bearing and bearing, be installed with multi-disc wet clutch on live axle He in the wheel hub, this multi-disc wet clutch is by: driving disc, constitute from movable friction plate, active friction plate, spring, pressing plate, screw.This driving disc is solidly set on the live axle, active friction plate is housed on the driving disc, boss cover from the movable friction plate cylindrical is stuck in the tongue and groove in the wheel hub, spring is arranged between pressing plate and the driving disc, two ends are rest against pressure plate and driving disc respectively, screw links together pressing plate and driving disc by the center hole of spring, is provided with the device of roof pressure pressing plate at the outer surface of pressing plate.
The device of roof pressure pressing plate is to be made of plane bearing, gland and push rod.Plane bearing is near the outer surface of pressing plate, and gland covers on plane bearing, and push rod withstands on the gland outer surface, and push rod is by hub cap and foot-propelled or manual braking device connection.
Effect of the present invention is its fuel-economizing effectively, reduces the operating time of motor, prolongs the life-span of motor etc., has the excellent safety energy again simultaneously, promptly can utilize the braking function of motor to brake at any time.
Description of drawings
Fig. 1 is a sectional view of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is further set forth.
Referring to Fig. 1: on the interior circle of wheel hub 1, be provided with-tongue and groove of cast boss and outer clutch drum shape, bearing 2 is installed on the cast boss in the wheel hub 1, left end at wheel hub 1 is fixed with an above guide bearing 3, oil sealing 4, cast boss in guide bearing 3 and the wheel hub 1 against, live axle 5 is by oil sealing 4, the center circle borehole jack of guide bearing 3 and bearing 2 is stuck in the wheel hub 1, admittedly be set with driving disc 6 (driving disc 6 covers are stuck on the external diameter of live axle 5) on the external diameter of live axle 5 right-hand members and in the right-hand member of wheel hub 1 successively, from movable friction plate 7 (the boss cover from movable friction plate 7 cylindricals is stuck in the cast tongue and groove in the wheel hub 1), active friction plate 8, spring 9, pressing plate 10, screw 11, plane bearing 12, gland 13, push rod 14, between pressing plate 10 and driving disc 6, be provided with four springs 9, the two ends of spring 9 are rest against pressure plate 10 and driving disc 6 respectively, screw 11 spins with driving disc 6 by pressing plate 10 and spring 9, spring 9 is when relaxed state, separate with active friction plate 8 from movable friction plate 7, spring 9 is when impaction state, be close to active friction plate 8 from movable friction plate 7, plane bearing 12 is near the outer surface of pressing plate 10, gland 13 covers on plane bearing 12, push rod 14 is resisted against on the gland 13, push rod 14 is by hub cap 15 and foot-propelled or manual braking device connection, oil sealing 16 and hub cap 15 are housed in the right-hand member of wheel hub 1, hub cap 15 is fixed on the back chain stay of motorcycle, and brake disc 17 is by the right side of screw 18 stationary hub 1; The interior circle of oil sealing 16 is enclosed on the cylindrical of hub cap 15, oil sealing 19 and oil sealing 20 are housed respectively on hub cap 15, the interior circle of oil sealing 19 is enclosed on the cylindrical of live axle 5 right-hand members, the interior circle of oil sealing 20 is enclosed on the cylindrical of push rod 14, axle sleeve 21 is housed in the center hole of live axle 5, bearing 22 is housed in the hole at live axle 5 two ends successively, oil sealing 23, the two ends of axle sleeve 21 are respectively against bearing 22, the two ends, the left and right sides of axle sleeve 24 and axle sleeve 25 suit rear-wheel spindles 26, axle sleeve 21, the cylindrical of axle sleeve 24 and axle sleeve 25 should be less than the external diameter of bearing 22 inner cores, the interior circle of oil sealing 23 is enclosed on the cylindrical of axle sleeve 24 and axle sleeve 25, driving sprocket wheel 27 is fixed on the right side of live axle 5 by screw 28, and rear-wheel spindle 26 is fixed on the back chain stay of motorcycle by the center hole of live axle 5.
Working procedure of the present invention is: when motor cycle rear wheel rotating speed during greater than engine speed, wheel hub 1 is separated with live axle 5 and does relative running, be that motorcycle enters sliding state, this moment, motor was in idling, when lower long slope or when needing engine braking, brake activation device then, with push rod 14 roof pressure pressing plates 10, pressing plate 10 is that spring 9 is in compacted state behind pressurized, be close to active friction plate 8 from movable friction plate 7, thereby make 5 one-tenth of wheel hub 1 and live axles as a whole, promptly the rotating speed of trailing wheel is realized the braking function of motor fully by the motor restriction.
The present invention both can be used on the straddle type motorcycle, also can be used on the pedal motorcycle, also can be used on compact car and other motor vehicle.
