Description
The utility model relates to a kind of transmission additional device that is used for automobile, is installed between gearbox and the driving wheel, specifically is a kind of overdrive clutch variable speed energy saving transmission device.
Existing vehicle gear box power output is connected with driving wheel by a semiaxis, and under the situation of driver's non-refuelling door, wheel produces reverse drag power for motor, and Vehicle Speed is obviously descended, and operating range obviously shortens.
A kind of automobile variable speed energy saving transmission device is disclosed among the Chinese patent ZL00245613.3, be installed between the gearbox and driving wheel of front wheel driving vehicle, it is by distinctive unidirectional output function, wheel is cut off for the reverse drag power of motor, for reaching the passive wearing and tearing of saving oil plant and reducing motor.But in actual using process afterwards, find that this technological scheme exists that following some is not enough: 1, the working surface of mandrel is parallel, with overcoat formation triangle, makes roller can not wedge dead during work, easily skids; 2, spring sheet is used in the location of roller, does not play the effect of location, because spring sheet does not have elasticity; 3, the diameter of the diameter of mandrel and overcoat coupling is improper, monolateral excesssive gap, when the rotating speed of overcoat surmounts the rotating speed of mandrel, strengthened friction,, be lower than the radius of roller again because of the tooth depth of mandrel to making roller do reversing motion to roller, under the promotion of reaction force, roller cuts off spring sheet, makes mandrel inside stuck, can't use.Thereby this technological scheme perfect necessity that is further improved.
The problem that the purpose of this utility model exists at prior art and a kind of overdrive clutch variable speed energy saving transmission device is provided, reduces the element consumption at designs simplification, saves oil consumption, alleviates environmental pollution, and when reversing or climb and fall, handling safety is reliable.
The purpose of this utility model is achieved through the following technical solutions: a kind of overdrive clutch variable speed energy saving transmission device, comprise active body, driven member and mandrel, described active body and driven member are installed in respectively on the two-end part of described mandrel, be respectively equipped with on the described active body two-end part and be used for the active land and the driving gear that are connected with output shaft of gear-box, described active body and described mandrel are fixed together; Be respectively equipped with driven gear and the driven land that is used for being connected with wheel hub on the described driven member two-end part, described driven member is supported on the described mandrel by pair of bearings; An axially displaceable gear ring that is meshed with it is housed on described driving gear and driven gear; Be provided with free wheel device on the mandrel in described driven body cavity between the bearing of the described driven member of support, described free wheel device comprise on described mandrel cylindrical and and circumferentially uniform at least three cambered surface blocks and the fan groove between the cambered surface block in its edge that fuses, the interior circle of the cylindrical of described cambered surface block and described driven member is complementary, tangent direction along described mandrel in the described cambered surface block is provided with plunger hole, and plunger and pressure spring are housed in the described plunger hole; Be equipped with in the described fan groove that axis parallels with described wire mandrel and with corresponding roller of described plunger or voussoir, described roller or voussoir contact with described plunger one end.
The utility model adopts technique scheme, and have following some effect: 1, oil-saving effect reaches more than 30%: but 2, in driving the gearshift not stepping on clutch, can shift gears arbitrarily after receiving oil, form stepless change; 3, alleviated environmental pollution; 4, prolonged the life-span of clutch plate and motor.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the utility model mandrel block schematic representation.
Shown in Fig. 1-2, a kind of overdrive clutch variable speed transmission fuel economizer, be installed between the gearbox and driving wheel of front wheel driving vehicle, comprise active body 3, driven member 7 and mandrel 11, described active body 3 and driven member 7 are installed in respectively on the two-end part of described mandrel 11, are respectively equipped with on described active body 3 two-end parts to be used for the active land 1 and the driving gear 4 that are connected with output shaft of gear-box, and described active body 3 is fixed together with described mandrel 11; Be respectively equipped with driven gear 6 and the driven land 9 that is used for being connected with wheel hub on described driven member 7 two-end parts, described driven member 7 is bearing on the described mandrel 11 by pair of bearings 10; An axially displaceable gear ring 5 that is meshed with it is housed on described driving gear 4 and driven gear 6.
Shown in Fig. 2-3, on the mandrel 11 between the described driven member 7 chamber internal support driven member bearings 10, be provided with free wheel device, described free wheel device comprises at least three cambered surface blocks 14 and the fan groove between cambered surface block 14 17 that the edge on described mandrel 11 cylindricals is circumferentially uniform, the interior circle of the cylindrical of described cambered surface block 14 and described driven member 7 is complementary, tangent direction along described mandrel 11 in the described cambered surface block 14 is provided with plunger hole 15, plunger 12 and pressure spring 16 are housed in the described plunger hole 15, are provided with exhaust port 18 in the described plunger hole 15; Be equipped with in the described fan groove 17 axis parallel with the axis of described mandrel 11, with described plunger 12 corresponding rollers or voussoir 8, described roller or voussoir 8 contact with described plunger 12 1 ends.
As shown in Figure 1, described active body 3 is fixing via nut 2 and flat key 13 with described mandrel 11.
