Below in conjunction with accompanying drawing the utility model is described in further detail:
The utility model is exactly the deficiency at the vehicle wheel clutch that installs additional in the energy-conservation car transmission system, a kind of novel vehicle wheel clutch is provided. make in engine misses vehicle free-wheel, wheel can thoroughly separate with a whole set of transmission system, to realize the effect of vehicle free sliding.When the speed of a motor vehicle drops to certain numerical value, when motor need restart, can guarantee wheel and a whole set of driving mechanism again in the process that combines again, the impact of generation is enough little.The vehicle wheel clutch that installs additional in a kind of energy-conservation car transmission system is on the basis of component such as existing wheel hub, rear axle, transmission hinge wheel and return spring, has increased the ratchet with new structure, flange seat, ratchet and release sleeve part.
Consult Fig. 2 and Fig. 4, ratchet 2 is structural members of a cirque body formula, and its end is processed with the levogyrate inner thread that is connected usefulness with rear-wheel hub 1, and the other end is processed with the ratchet internal tooth that matches with ratchet 4.
Consult Fig. 5 to Fig. 7, ratchet 4 is long strip entity structure parts that surrounded by curved surface and plane.The ratchet 4 that is adopted in the utility model is more than ratchet length used in the prior art, and in other words, the length of ratchet 4 is considerably beyond its active length that is meshed with ratchet 2 teeth.Ratchet 4 lower ends are cylndrical surface, the upper end is a plane inclined, the inboard is a curved surface, and promptly ratchet 4 and ratchet 2 are thrown off back ratchet 4 fully near the face on the groove floor of having processed on the flange seat 3, and is processed with the groove of placing return spring 11 along its short transverse, the trench cross-section shape can be a triangle, also can be circular shape, the outside also be a curved surface, promptly towards the face of the interior gear teeth of ratchet, ratchet 4 is the plane at two end faces of length direction, also is plane inclined after the processing of the upper left corner.
Consult Fig. 8 and Fig. 9, flange seat 3 is by the ladder flange plate that is evenly equipped with through hole and the one-piece parts that cirque body is formed, their rotational axis conllinear.Being designed to ladder flange plate one is to be convenient to be located by connecting with transmission hinge wheel 8, is the length that lengthening holds ratchet 4 on the other hand, makes ratchet 4 energy stable working under the operating mode of rotation.On toric external cylindrical surface, process two penetrating grooves vertically up and down symmetrically, this groove is surrounded by curved surface and plane, the bottom surface of groove is a curved surface, the end face of groove is a curved surface, the rotational axis conllinear of the rotational axis of two curved surfaces and flange seat 3, the groove left side is the plane parallel with the cirque body symmetry plane, and the right side is a plane inclined, and the connection bottom surface is the cylndrical surface of matching with ratchet 4 lower end cylindrical bodys with the right side clinoplain.At groove plane, left side and circular hole that return spring 11 is installed of groove floor surface intersection place processing.In fact these two penetrating grooves just have end face in the position that the ladder flange plate is arranged, and are not have end face in the end positions that does not have the ladder flange plate, are opening wide.
Consult Fig. 1 and Fig. 3, release sleeve 5 is structural members of a drum type, be processed with on its axis of symmetry with linear bearing 6 and flange seat 3 on be processed with the shoulder hole that two penetrating groove parts match, process an internal conical surface at the round mouth end of major diameter circular hole.Being processed with the cross section that matches with shift fork in the outside of minor diameter circular hole is the circular groove of rectangle.
The working principle of vehicle wheel clutch:
1. nominal situation transmits the working principle of Engine torque down:
Consult Fig. 1 and Fig. 2, engine torque has been delivered on the transmission hinge wheel 8 through chain after a series of transmission, by 4 connecting bolts, has been delivered on the flange seat 3.The groove of flange seat 3 by matching with ratchet 4, with transmission of torque to ratchet 4.
The release sleeve 5 of this moment makes it be in the position of high order end by handling shift fork.Ratchet 4 is under the effect of return spring 11, on the tooth that withstands on ratchet 2 tightly like this.So torque just can be delivered on the ratchet 2 by ratchet 4.
Afterwards, by the left-handed thread on ratchet 2 and the rear-wheel hub 1, torque further is delivered on rear-wheel hub 1, spoke 9 and the trailing wheel wheel rim 10.Thereby realized that Engine torque is to the transmittance process of trailing wheel under the nominal situation.
2. wheel separates the working principle under the operating mode with driving mechanism:
When motor was just flame-out, vehicle was in the coast state.Transmission hinge wheel 8 rotating speeds that are connected with motor drop to zero very soon; And trailing wheel wheel hub 1 is owing to link to each other very slow (can be similar to and think that rotating speed is constant) that its rotating speed descends with the trailing wheel that drives complete vehicle quality.This moment is not if handle shift fork, and make release sleeve 5 still be in the position of high order end, so present transmission system just can be similar to regards a mechanism that free wheel device is installed as, though rear-wheel hub 1 can not instead be with hinge wheel 8 to rotate, the tooth of ratchet 2 and ratchet 4 exist insignificant frictional loss.
Consult Fig. 3 and Fig. 4, make release sleeve 5 be in the position of low order end by handling shift fork this moment.Owing to processed internal conical surface in the rightmost side of release sleeve 5, and processed the inclined-plane in the upper left corner of ratchet 4.This just makes and moves in the process of low order end position at release sleeve 5, in the groove that surely ratchet 4 is pressed on the flange seat 3, even it is in the position of throwing off fully with the tooth of ratchet 2.Thereby just realized that also trailing wheel and whole drive system throw off fully, at this moment vehicle just is in the state of real free sliding, does not have insignificant frictional loss, thereby its Economy is improved.
3. wheel and the driving mechanism working principle under the clutching operation again:
Consult Fig. 1 and Fig. 2, when the speed of a motor vehicle drops to certain numerical value, motor need restart torque is passed on the trailing wheel again.At this moment only need to handle shift fork, release sleeve 5 is on the position of high order end again, like this, ratchet 4 has the trend on the tooth that withstands on ratchet 2 that is in again tightly under the effect of return spring 11.
Because rear-wheel hub 1 has speed discrepancy with transmission hinge wheel 8, in the process of combination, may cause impact. at this moment need special control to handle the opportunity of shift fork. total principle is will guarantee when handling shift fork, and the rotating speed of rear-wheel hub 1 (and rotating speed of ratchet 2) is greater than the rotating speed (and rotating speed of ratchet 4) of transmission hinge wheel 8.The method of insuring was most handled shift fork exactly before engine restart.
Satisfy above-mentioned requirements the opportunity of shift fork as long as handle, the transmission system of this moment is just closely similar with the situation that free wheel device (for example bicycle freewheel) has been installed.That is to say and since the wheel wheel hub 1 rotating speed greater than hinge wheel 8, the torque of motor can't be delivered on the trailing wheel 10.The existence of speed discrepancy has caused ratchet 4 " surmounting " for ratchet 2 teeth, can not produce impact.
At this moment only need strengthen engine throttle gradually, improve the rotating speed of whole drive system.When the rotating speed of ratchet 4 strengthens gradually, and during just above ratchet 2, the torque of motor just can be delivered on the trailing wheel very stably.
This moment, vehicle reentered the process of transmitting Engine torque under the above-mentioned nominal situation, and whole wheel finishes with the process that driving mechanism engages again, and does not produce bigger impact phenomenon in the process that engages.
