Described input shaft parts, intermediate shaft part, output shaft assembly all are installed on the box part by rolling bearing; The axle head of input shaft is provided with the inner spline housing for the power input; The output shaft two ends of output shaft assembly are provided with output flange.
Be provided with left and right oil hydraulic cylinder in the described gearshift parts, oil hydraulic cylinder is built-in and be made of one with casing.
Respectively there is a position limit switch left and right oil hydraulic cylinder inside in the described gearshift parts.
Input shaft parts shaft end described in the utility model has inner spline housing, and an end is for the power input, and the other end is connected with input shaft; The gear of two band tooth inserted tooth grooves floats on jack shaft on the intermediate shaft part, the move left and right of the sliding sleeve by having the tooth inserted tooth realize respectively with the joint of the left and right gear that floats with separate, realize gearshift, sliding sleeve mobile is that the shift fork by the gearshift spindle unit promotes to realize; The gearshift parts left and right oil hydraulic cylinder is housed, by oil hydraulic cylinder dash oil, draining the oil promotes the selector fork move left and right, oil hydraulic cylinder and casing are to make an integral body; Output shaft assembly is positioned at the below of speed reducer, and two gears are connected and fixed by spline and are installed on the output shaft; This gearbox has compact structure, in light weight, convenient to operation, gearshift steadily, characteristics such as operational safety height.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, the utility model mainly is made up of input shaft parts 1, intermediate shaft part 2, output shaft assembly 3, gearshift parts 4, box part 5, it has three pairs of gear transmissions, input gear 11 is made of one with input shaft 12, and meshes with the intermediate gear 21 that is fixed on the jack shaft 22; Jack shaft 22 is made of one with intermediate gear 21, indented joints in this intermediate gear 21 and the sliding sleeve 41, two unsteady driving gears were listed in the both sides of this intermediate gear 21 in 42 minutes, respectively be fixedly mounted on two output gears 32 engagements on the output shaft 31.
Described jack shaft 22 is for having the shaftgear of external splines, and the intermediate gear 21 on it is equipped with the sliding sleeve 41 of a band internal spline, and sliding sleeve 41 is provided with the tooth inserted tooth that can be connected with the output gear 32 of both sides.
Described input shaft parts 1, intermediate shaft part 2, output shaft assembly 3 all are installed on the box part 5 by rolling bearing; The axle head of input shaft 12 is provided with the inner spline housing for the power input; Output shaft 31 two ends of output shaft assembly 3 are provided with output flange 33.
Be provided with left and right oil hydraulic cylinder in the described gearshift parts 4, oil hydraulic cylinder is built-in and be made of one with casing.
Respectively there is a position limit switch left and right oil hydraulic cylinder inside in the described gearshift parts.Oil hydraulic cylinder dash oil, draining the oil promotes selector fork, selector fork promotes the sliding sleeve 41 of band tooth inserted tooth, its left and right driving gear 42 with band tooth caulking groove is engaged realize shift gears two keep off speed reduceres, oil hydraulic cylinder is built-in, and has position limit switch.
Power drives input shaft 12 rotations (input gear and input shaft are made an integral body) by inner spline housing; Input gear 11 on the input shaft 12 drives by spline and connects intermediate gear 21 rotations that are fixed on the jack shaft 22, and jack shaft 22 and sliding sleeve 41 are connected by spline, so power reaches on the sliding sleeve 41 of being with the tooth inserted tooth; By lead to, put pressure oil to oil hydraulic cylinder, realize the mobile promotion shift fork 43 of piston in hydraulic cylinder slide block, shift fork 43 moves sliding sleeve 41 move left and right that promote band tooth inserted tooth; When sliding sleeve 41 moves to the left, power just reached on the driving gear 42 of left side when the tooth inserted tooth on the sliding sleeve engaged with the tooth caulking groove of left side driving gear 42, left side driving gear 42 drives an output gear 32 that is fixed on the output shaft 31, at this moment the rotation of output shaft 31 drives the rotation of output flange 33, the output of realization power is to be 2 retainings; In like manner, when sliding sleeve 41 moves to the right, realize being connected of an other output gear 32 on right side driving gear 42 and the output shaft 31, at this moment the rotation of right side driving gear 32 drives output shaft 31 rotations, the rotation of output shaft 31 drives the rotation of output flange 33, realizes power output, is to be 1 retaining.When gearshift finished, the piston slider in the oil hydraulic cylinder touched the built-in position limit switch of oil hydraulic cylinder simultaneously, and external tutorial light reminds the operator to cut off the pressure oil that enters oil hydraulic cylinder.
