Be described further with reference to the accompanying drawings:

Fig. 1 is applicable to the sliding fuel-saving device structural drawing that is installed in semiaxial position, and Fig. 2 is mounted in the sliding fuel-saving device structural drawing of driving gear front end, and the two working principle is identical, similar, just installation position difference; Not shown semiaxis among Fig. 1, (right elevation is not drawn lid) do not need semiaxis among Fig. 2; 1 is lid, 2 bearings, 3 clutch blocks, 4 springs, 5 shells, 6 fuses, 7 bracers, 8 spring mechanisms, 9 bearings, 10 oil sealings among the figure.Clearly show the curve shape of clutch block, bracer and several breach among the figure, geometric figure and position relation; Fuse 6 can separate with semiaxis as other part separately among Fig. 1, and recombinant together during assembling; Also can directly make a semiaxis, the end that this root semiaxis is connected with differential gear has spline, and the other end is then made by the requirement of fuse, after the assembling promptly as a complete semiaxis.

Among Fig. 1 and Fig. 2 shell 5 with and fuse 6 clamped bracer 7, clutch block enters in the breach of fuse under the spring force effect when low speed or parking, the size of this breach is greater than clutch block, make both sides that tangible gap all be arranged, when not reaching sliding speed when vehicle take-offs, transmission of power rotates shell to semiaxis and by fuse and bracer, and powered vehicle to overtake; (be assumed to 40Km/h) when travelling speed reaches automatic sliding speed, clutch block overcomes spring force indentation one segment distance in shell under centrifugal action, and when motor drops to idling, this moment, vehicle began to slide under the inertial force effect; When sliding clutch block then along the high low step place of fuse breach H along the direction of arrow, constantly cross the breach that bracer is hidden oneself on the fuse and advance.

Clutch block has multiple shape, has square or an end is square, and the other end is half garden shape; The garden cylindricality is also arranged, existing explain with the garden cylindricality, skip breach on the fuse as using the garden post smoothly sliding Shi Gengneng, constantly slide, when speed was low, the garden post entered in the breach, stopped sliding the realization combination; Stress surface is even because it is the garden perimeter surface of whole garden post that the garden of use post contacts with fuse when sliding, rather than is fixed on a position, and bump is light, so not fragile; During employing garden post (or ball) structure, shell 5, on the breach that clutch block is installed, interior garden Zhou Chu, both sides have a r(inclined-plane also can), during reversing and during descending, the r on fuse and the shell clamps clutch block, prevents that effectively clutch block from jumping out from fuse, improved Security, and on fuse, have with clutch block match, breach that shape is similar, Yi Bian and cutting out an inclined-plane that H is high so that clutch block jumps to when sliding on this inclined-plane.

Find out that from Fig. 1, Fig. 5, Fig. 6, Fig. 7 the position diameter that mechanisms such as clutch block, bracer are installed is less than the flange plate diameter that connects with wheel hub, this designs simplification processing technology.

Fig. 3 is a sliding fuel-saving device motion conditions schematic representation, be that Figure 1A amplifies, this figure is that example explains with the garden post, a. cruising, this moment, the garden post was clamped the power that is transmitted by fuse and shell, be passed to shell by the garden post, during low cruise, clutch block is defeated in the breach of fuse by spring 4, i.e. position shown in the solid line among the figure; Accelerate when opening slip velocity degree (given by design, for example 40Km/h) when Vehicle Speed, under the action of the centrifugal, clutch block is in dotted line position, and this moment as reduce throttle, the fuse rotating speed reduces, the shell faster rotational speed, and vehicle just begins to slide.B slides, and is when vehicle has big speed, (given by design greater than on-slip speed-on-slip speed, 7Km/h for example) time, clutch block (moves to solid line position by dotted line position) when skipping the fuse breach, can not fall into the breach of fuse, but jumps to the left side of fuse breach, the H height owing to pruned in the left side, an inclined-plane is arranged again, and little angle, garden is arranged, simultaneously because of clutch block this as the garden cylindricality, when shown position moves in the direction of arrows, be pushed into again in the breach of shell; When speed during less than on-slip speed, clutch block is unable to be jumped on the inclined-plane, under the spring force effect, can only fall into the breach of fuse, thereby stops sliding; As think to slide continuously, only need before reaching on-slip speed, to reduce throttle after the several seconds of opening the throttle again fast and get final product.C is that the garden post is clamped in another position by fuse and shell, and this moment, clutch block was ensconced in the shell, and vehicle can cruising, and slides than being easier to realization, but clutch block is entered in the breach of fuse; D shows two kinds of working staties, and when arrow is pressed shown in the dotted line, the fuse band the garden post distance that moves right, and the garden post is clamped by the r on shell the right, then drives the wheel reversing and realizes reversing; When descending, the shell rotating speed is greater than the fuse rotating speed, and shell is moved to the left a distance, also the garden post is pushed down it can not be jumped out, so the speed of vehicle descending is subjected to the control of engine speed, thus safe and reliable.

Fig. 4 and Fig. 9 are the collocation forms of clutch block and bracer.The form of clutch block is had nothing in common with each other, but function all is to realize opening automatically sliding and reach normally in conjunction with on-slip automatically moveing backward; The part shape in addition of clutch block mainly contains the garden cylindricality, and (Fig. 4 a), bracer rocking arm shape (Fig. 4 b) square (shown in Fig. 4 c dotted line), one end is that the square the other end is the spherical ball (Fig. 4 d) of half garden shape (shown in Fig. 4 c solid line) and garden, also can carry out close distortion, how tube shape all must not accomplished, when reaching out slip velocity and spending, under centrifugal action, overcome spring force, be hidden in the shell; When rotating speed was lower than on-slip speed, centrifugal force disappeared substantially, under the spring force effect, got back to shown position again; The part 7 in addition that indicates among Fig. 1 and Fig. 2 and Fig. 9 is bracers, its function is that fuse and shell are propped up, make vehicle to overtake with transferring power, the part shape has similar ratchet shape in addition, garden cylindricality and garden are spherical and square etc., and it is varied that the form that it and clutch block are arranged in pairs or groups has, and how to select for use, should determine according to the size of transmitted power and the physical dimension of parts, no matter select for use which kind of shape all identical with effect, but with garden cylindricality and square processing most convenient, it is the most flexible to move with its function of how arranging in pairs or groups, when transmitted load hour, for example be used for sedan car, bracer can be used nonmetal manufacturing, but also outsourcing one deck is nonmetal for clutch block, can avoid bump and reduce lubricating requirement, bracer adopts squarely among Fig. 9 a, can slide in groove, adopts many springs among the b, be reed among the c, its sectional shape can be as shown in a or c; The place that matches with it on the shell will carry out corresponding improvement.

Fig. 5 is the combining form of semiaxis in the sliding fuel-saving device.A separates manufacturing with fuse and semiaxis, the time combines in assembling again, and the connecting means of semiaxis and fuse can be with singly-bound or spline; B becomes a part in addition with fuse and semiaxis, and the profile that makes whole sliding fuel-saving device is just as a semiaxis that has flange plate, and the hole among the figure and ransaxle or brake drum, steel ring are connected.

Shown in the accompanying drawing 1, be not dispose semiaxis, promptly do not have and the sliding fuel-saving device that is assembled together of semiaxis that the therefore profile of alleged sliding fuel-saving device can be as Fig. 1, Fig. 2 and shown in Figure 5.They remove and can be contained on the vehicle of rear bridge driven, also are applicable to the vehicle that is installed in propons and doube bridge driving; Both can be installed in the left side, also can be installed in the right side, and only need that other part moving direction and relevant size are done corresponding change and get final product.
