Abstract

The utility model relates to a gear box which belongs to the mechanical transmission field. The technical proposal is that the gear box comprises a first shaft, a second shaft, a third shaft and a fourth shaft; the first shaft is equipped with a dead wheel; the second shaft is equipped with two shifting slide gears or a shifting slide gear and an unilateral gear; the their shaft is equipped with two dead wheels; the dead wheel of the first shaft can be meshed with the shifting slide gear or the unilateral gear of the second shifting slide gear; the shifting slide gears of the second shaft can be meshed with the dead wheel of the third shaft and a differential gear ring; the other dead wheel of the third shaft is normally meshed with the differential gear ring. The gear box has the beneficial effect that the gear box has reasonable design and simple structure; single power input can be used, and double power input can also be used; the gear box is convenient, economical and practical; fuel can be used as auxiliary power input, thereby facilitating environmental protection.

Description

Gearbox

Technical field

The utility model relates to a kind of speed change gear, relates in particular to a kind of gearbox.

Background technique

The gearbox of prior art can only adopt a kind of power input device, and a kind of is adopted the input of fuel oil power, its operation cost height, uneconomical but also befouling environment; A kind of is adopted motoring, but the deficiency that drives is the finite capacity of storage battery, and easy electric weight deficiency in the time of long-distance running is difficult for charging, so its distance of travelling has certain narrow limitation in the way.

The model utility content

The utility model is at the existing in prior technology shortcoming, and provide a kind of simple in structure, reasonable in design, can adopt double dynamical input, the technological scheme of the gearbox of economic environmental protection.

The utility model is realized by following technical measures: it comprises one, two, three and four, fixed gear is installed on one; Be equipped with on two on two shifting slide gears or two shifting slide gear and a ratchet are installed; Two fixed gears are installed on three; A fixed gear and two shifting slide gears can mesh, two another shifting slide gears can with three fixed gears and the engagement of differential mechanism gear ring, three another fixed gears and differential mechanism gear ring often mesh.Use the advantage of the technical program to also have, when power is input as two, the shifting slide gear on two with one on the fixed gear disengagement, one need not be dallied, save energy.

Above-mentioned one can be adopted two kinds of designs, and it can directly be a motor output shaft, can cut one like this, replaces one with motor output shaft, reduces cost; Certainly, also can be one fixedlys connected with motor output shaft.

Fixedly connected with engine output shaft for above-mentioned two.Can adopt double dynamical input like this, economic environmental protection.

The beneficial effects of the utility model are, it is reasonable in design, and designs simplification, the utility model both can adopt the input of single action power, also can adopt double dynamical input, and are convenient economical and practical, and fuel oil can be used as the auxiliary power input, helps environmental protection like this.

Embodiment

For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by an embodiment.

The utility model is a gearbox, and it comprises on one 11, two 9, three 5 and four 12, one 11 fixed gear 10 is installed; Mounting slip gear 7 and shifting slide gear or ratchet 8 on two 9; Fixedly small gear 6 and fixedly gearwheel 4 are installed on three 5; Fixed gear 10 and two shifting slide gears or ratchet 8 engagements, two shifting slide gears 7 can with three fixedly

gearwheel

4 and 3 engagements of differential mechanism gear ring, three 5 fixedly small gear 6 and differential mechanism gear ring 3 often mesh.One is motor output shaft or fixedlys connected with motor output shaft; Fixedly connected with engine output shaft for two.

Transmission process of the present utility model is as follows:

When 1, importing as power with motor:

Forward gears: two are connected with engine output shaft, two shifting slide gears 7 and 3 engagements of differential mechanism gear ring, and driving four just changes;

Reverse gear: two are connected with engine output shaft, two shifting slide gears 7 and three fixedly gearwheel 4 engagements, three fixedly small gear 5 often mesh with differential mechanism gear ring 3, drive four 12 counter-rotatings.

When 2, importing as power with motor:

Forward gears: fixed gear 10 and two shifting slide gears or ratchet 8 engagements, two shifting slide gears 7 and 3 engagements of differential mechanism gear ring, driving four just changes;

Reverse gear: fixed gear 10 and two shifting slide gears or ratchet 8 engagements, two shifting slide gears 7 and three fixedly gearwheel 4 engagements, three fixedly small gear 5 and differential mechanism gear ring 3 often mesh, drive four 12 counter-rotatings.

In use the drive path of this embodiment is as follows:

When 1, importing as power with motor:

Forward gears: two shifting slide gear 7-of two 9-differential mechanism gear ring 3-output;

Reverse gear: three fixedly three fixedly small gear 6-differential mechanism gear ring 3-outputs of three 5-of gearwheel 4-of two shifting slide gear 7-of two 9-.

When 2, importing as power with motor:

Forward gears: two shifting slide gears of fixed gear 10-of (or motor shaft) 11-or two shifting slide gear 7-of two 9-of ratchet 8-differential mechanism gear ring 3-output;

Reverse gear: three fixedly three fixedly small gear 6-differential mechanism gear ring 3-outputs of three 5-of gearwheel 4-of two shifting slide gears of fixed gear 10-of (or motor shaft) 11-or two shifting slide gear 7-of two 9-of ratchet 8-.
