Four, description of drawings
Be elaborated below in conjunction with accompanying drawing:
Figure is the utility model embodiment's a unfolded drawing.
Five, embodiment
In the drawings, for inside for for the motor of automatic clutch, chain transmission, its front portion is just before the driven sprocket (5), comprise the engine main body part that constitutes by combustion system, gas distribution system, lubrication system, start-up system and electrical system etc., these technology are mature technique in related domain, and this place repeats no more.As main contribution of the present utility model be from input shaft (6) begin to be provided with the transmission gear changing mechanism, box of tricks is the gearbox designs of main body, this gearbox designs is different from the external gearbox in the prior art, but place in the engine housing, transmission gear changing mechanism and box of tricks organically combine, and make motor each several part cooperation.
Input shaft (6) right-hand member is supported in the circular hole of left box body inboard, the middle part by roller bearings on left case lid (11), left end is supported on the transmission-case cover (12) by needle bearing, be provided with back-up ring and thrust washer respectively in the left side of rolling bearing and the right side of needle bearing, together with the shaft shoulder of input shaft, this axle is played position-limiting action.On input shaft (6), be provided with driven sprocket (5) successively, pleasure boat (20), driven sprocket (5) and input shaft (6) interference fit; Pleasure boat (20) is a Spielpassung with input shaft, and can realize moving axially on input shaft, which is provided with and the corresponding fork slot of variable block shift fork.Idler shaft (7), (8), two ends all are supported on left case lid (11) and the transmission-case cover (12) by rolling bearing and needle bearing.End to idler shaft (7), (8) needle bearing also is provided with thrust washer, and idler shaft is spacing by the both sides shaft shoulder.Upward be provided with idle gear (16), (17) successively by spline at idler shaft (7), it is spacing that back-up ring is established in the outside of the two.On idler shaft (8), be provided with driving gear (24) successively, idle gear (18), (19), wherein driving gear (24) is an one with idler shaft (8), idle gear (18), (19) are connected for spline with idler shaft (8).Differential mechanism (15) is gone up and is connected with driven gear (10) by key.Their contact is: idle gear (16) is normal engagement with idle gear (19), driving gear (24) with these two groups of gears of driven gear (10); Pleasure boat (20) can be realized the engagement with idle gear (17), (18) respectively under the effect of variable block operating mechanism.That is to say, under normal state, advance when travelling that pleasure boat (20) only meshes with idle gear (17); Reverse gear when travelling when being operating as, pleasure boat (20) only meshes with idle gear (18).
Differential mechanism (15) is built in the rear portion of motor by a pair of rolling bearing in embedding left case lid (11), the transmission-case cover (12).Its two ends, left and right sides have output semiaxis (9), (14) respectively, the outer end of output semiaxis (9), (14) is supported on respectively on left box body (3), the land (13) by a pair of rolling bearing, is provided with the structure that matches with hub for vehicle wheel at left box body (3), land on (13).The principle of box of tricks is a known technology already, and this place repeats no more.
The variable block operating mechanism by two ends be fixed on the casing and axially movable variable block axle (22), with the variable block shift fork (25) of variable block axle (22) one, and place on the variable block axle (22) and be limited in variable block shift fork (25) and transmission-case cover (12) between a position control spring (23) form, the end of variable block shift fork (25) places in the fork slot of pleasure boat (20), and an end of lacing wire line (21) is connected with an end of variable block axle (22) by behind the supporting frame.
In the present embodiment, the lubricated of transmission case internals communicates with the lubricated of engine housing inner sprocket, chain.For preventing oil leakage, between variable block axle (22) and the transmission-case cover (12), between semiaxis (14) and the transmission-case cover (12) and be equipped with oil sealing between semiaxis (9) and the left box body.
The working conditions change of this motor is such: under the state, position control spring (23) is preloading condition usually, and this is a forward gear.Pleasure boat (20) and idle gear (17) engagement, automatic clutch after motor reaches certain rotating speed (1) engages, power drives input shaft (6) through drive chain (4), driven sprocket (5), pleasure boat (20) rotating drive idle gear (17), through idle gear (16), (19), driving gear 24) be delivered to the driven gear (10) that is connected with the differential mechanism key, drive differential mechanism and realize forward gear.Enter when reversing gear, tension lacing wire line (21) makes variable block axle (22) that axial displacement take place, compressed-bit control spring (23) puts in place, and pleasure boat this moment (20) and idle gear (18) engagement drive differential mechanism by driving gear (24), driven gear (10) and realize reversing gear.Unclamp and strain at muscle line (21), under control spring on the throne (23) the elastic force effect, variable block axle (22) resets, and enters forward gear.
When motor tricycle, four-wheel motor cycle straight-line travelling, differential mechanism is inoperative, and left and right sides semiaxis rotating speed is identical; When detour travelled, inside and outside wheel is rotating speed generation difference under the effect of differential mechanism, to adapt to the needs of detour.
Certainly, the utility model can also reverse gear for bel-drivenn has, the special engine of differential.So-called belt transmission (CVT transmission) promptly includes automatic clutch, one-level driving pulley, driving belt, one-level driven pulley at interior one-level power-transmission system.Motor for this kind form, before the one-level driven pulley, the one-level power-transmission system that comprises combustion system, gas distribution system, lubrication system, start-up system and electrical system and comprise clutch, driving pulley, driving belt, driven pulley, these technology are mature technique in related domain, and this place repeats no more.Be to begin to be provided with gearbox designs as main contribution of the present utility model based on transmission gear changing mechanism, box of tricks from input shaft, this gearbox designs is different from the external gearbox in the prior art, but be built in the engine housing, transmission gear changing mechanism, box of tricks organically combine, and make whole motor each several part cooperation.With regard to transmission reverse gear mechanism, box of tricks, basic identical with the foregoing description, different is that lubricant oil enters belt system and will cause transmission malfunctioning because belt transmission does not need to lubricate.For this reason, present technique will be by clutch, driving belt, belt wheel one-level transmission system that constitutes and the adjacent transmission reverse gear mechanism of using oil lubrication, box of tricks sealing.Establish lubricant oil honey seal apparatus between variable block axle, input shaft, secondary idler shaft, right axle shaft and left case lid, the bearing between right axle shaft and the left box body uses lubricating grease.Other structure is identical with first embodiment, no longer repeats.
