Abstract
A bidirectional roller cam energy saver is characterized in that a positioning liner 10 is sleeved with a reversing cam 9; the small end plane of the reversing cam 9 is provided with a reversing pin 11 which is connected with a brake steel rope 19; the reversing cam 9 is sleeved in a reversing brake disc 7; the shaft neck of the reversing brake disc 7 is clamped in the sidestep hole of an internal cam 5; the excircle of the internal cam 5 and the reversing brake disc 7 are sleeved with a sleeve 4; the right end of the sleeve 4 is provided with a dustproof cover 8. The positive roller 6 arranged in the working plane of the internal cam 5 is corresponding to a reverse roller 15. The utility model has the advantages of not changing the original motorcycle structure, saving the fuel, starting the sliding with gear of the engine, changing the gears at any moment in the driving process, also the utility model has the advantages of good sealing performance, convenient operation and safe application.
Description
The utility model relates to a kind of energy-saving apparatus for motorcycle, especially can realize the two-way roller cam economizer of two-way two controls.
Tradition chain wheel of motorcycle transmission is that driven sprocket directly is connected with wheel hub on the motorcycle by bolt, and the motor that is in operation can only be with shelves to work and slide, and its oil consumption is big, and mechanical wear is serious, and lack working life.At present, there is a kind of motorcycle Energy-saving coasting device to come out, this glider is mainly by driven sprocket, overcoat, positioning adapter, cam ring, the forward roller, the forward roller, compositions such as reset spring, its structure characteristic is: positioning adapter is set with cam ring outward, the outer suit overcoat of cam ring, put through screw outward and be connected with driven sprocket, driven sprocket is connected with wheel hub through bolt, and this Energy-saving coasting device sealing is poor, adopts friction catch, quick abrasion, the unidirectional energy-saving device can not realize that band shelves slide, and violates the regulation that Ministry of Communications can not neutral gear slides about Motor Vehicle, and the bi-directional energy-saving device easily produces phenomenon out of supply when being with shelves to slide, bring unsafe factor, and fuel consumption is big.
The purpose of this utility model provides a kind of two-way roller cam economizer, and by changing the internal structure and the arrestment mechanism of existing economizer, it is easily out of supply in motion to solve present economizer, and fuel consumption is big, and sealing is poor, serious wear, the problem that working life is short.
Concrete scheme of the present utility model is: comprise the wheel hub connecting bolt, dust guard, driven sprocket, overcoat, cam ring, the forward roller, the commutation brake disc, positioning adapter, elasticity location ball, the forward brake spring, the forward fore-set, reverse roller, reverse fore-set, the plugging spring, reset spring, it is characterized in that: be set with the commutation cam on the positioning adapter, the little Transverse plane of commutation cam is provided with the commutation pin, be connected with the braking steel cable on it, the commutation cam is sleeved in the commutation brake disc, the axle journal of commutation brake disc is installed in the step hole of cam ring, be set with overcoat on the cylindrical of cam ring and commutation brake disc, the right-hand member of overcoat is equipped with dust-proof cover.
Adopt such scheme need not change former motorcycle structure, both fuel savings, ato unit realizes that the band shelves slide at any time again, can shift gears at any time under steam, its good airproof performance, easy and simple to handle, safe in utilization.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is that the B of Fig. 1 is to view.
Please see Figure 1, Fig. 2, Fig. 3, the utility model is mainly by wheel hub connecting bolt 1, dust guard 2, driven sprocket 3, overcoat 4, cam ring 5, forward roller 6, commutation brake disc 7, dustproof cover 8, commutation cam 9, positioning adapter 10, commutation pin 11, elasticity location ball 12, forward brake spring 13, forward fore-set 14, reverse roller 15, reverse fore-set 16, plugging spring 17, reset spring 18, braking steel cable 19 compositions such as grade, its annexation is: driven sprocket 3 is sleeved on the overcoat 4, and link together through screw, dust guard 2 is housed in the step hole of driven sprocket 3, the step axle sleeve dress of the endoporus of driven sprocket 3 and cam ring 5, dust guard 2 and cam ring 5 link together through wheel hub connecting bolt 1 and driven sprocket 3, cam ring 5 outer suit overcoats 4, be provided with forward roller 6 between overcoat 4 endoporus and the cam ring 5, elasticity location ball 12, forward brake spring 13, forward fore-set 14, reverse roller 15, reverse fore-set 16, plugging spring 17, cam ring 5 is connected with reset spring 18; Structure characteristic of the present utility model is: the little Transverse plane that is set with commutation cam 9, commutation cam 9 on the positioning adapter 10 is provided with commutation pin 11, be connected with braking steel cable 19 on it, commutation cam 9 is sleeved in the commutation brake disc 7, the axle journal of commutation brake disc 7 is installed in the step hole of cam ring 5, be set with overcoat 4 on the cylindrical of cam ring 5 and commutation brake disc 7, the right-hand member of overcoat 4 is equipped with dust-proof cover 8.The forward roller of being installed in the working plane of cam ring 5 of the present utility model 6 is with oppositely roller 15 is corresponding.
Working principle of the present utility model is: economizer is connected on the rear wheel hub in motorcycle, start motorcycle engine, engine power drives overcoat 4 by sprocket wheel 3 and rotates, make plugging spring 17 promote reverse fore-set 16, oppositely fore-set 16 promotes the narrow end that reverse roller 15 enters braking contract groove, frictional force between reverse roller 15 and the overcoat 4 is increased, and oppositely roller 15 drives cam ring 5 and rear-wheel hub rotation, realizes the cruising of motorcycle.When motor enters idling mode, cam ring 5 is rotated further under effect of inertia, drive the wide end that reverse roller 15 enters braking contract groove, reverse roller 15 and overcoat 4 are broken away from, the realization fuel-economizing is slided, when booster engine again, pulling braking steel cable 19, braking steel cable 19 clockwise rotates commutation cam 9 by commutation pin 11, and commutation cam 9 drives commutation brake disc 7 simultaneously and rotates, overcome the elastic force of Returnning spring 18, at forward brake spring 13, under 14 effects of forward fore-set, forward roller 6 enters the narrow end of braking contract groove, under frictional force action, cam ring 5 drives forward roller 6, and forward roller 6 drives the normal idling of overcoat 4 formation and slides, at this moment, booster engine, motorcycle is realized cruising.
