Abstract
A mechanical shifting gearbox comprises a case-body part, an input part, a middle-axle part, an output part and a manipulation part; an input axle of the input part is movably enclosed with a first transmission gear, a second transmission gear and a third transmission gear and is connected with a oil pump force-fetching gear, a synchronizator is arranged between the second transmission gear and the third transmission gear and between the first transmission gear and the oil pump force-fetching gear, the first transmission gear, the second transmission gear and the third transmission gear on the input axle are separately engaged with a corresponding middle gear on the middle axle part; therefore, the utility model is characterized in having steady, fast and reliable shifting, obviously reducing the work intensity of the operator, only increasing a little production cost but greatly improving the quality of the operation system and greatly improving the competition capacity of the whole machine on the engineering market.
Description
Technical field
The utility model relates to a kind of gear transmission transmitting and converting device, be applicable to supporting use on the engineering machinery of road roller and similar properties or the special vehicle, belong to a kind of gear drive.
Background technique
At present, the road roller of domestic production, except that sub-fraction is the full hydraulic transmission, what adopt basically is the mechanical transmission of Purely mechanical gearshift,, because the valuable product of full hydraulic driving mechanism, domestic have only very little market share, and the speed changer of mechanical type gearshift is with low cost and reliability and durability, in current Domestic market still in occupation of leading position.But Purely mechanical manual transmission in use ubiquity following two problems: the one, and gearshift power is bigger, the gearshift difficulty, driver's labor intensity is big; The 2nd, in use exist " flutter " phenomenon, when climb and fall or chance obstacle, easily fall retaining simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provide a kind of follow-on, adopt synchromesh mechanical type gearshift mode, each retaining all has the mechanical changeover speed changer of synchronizer, it is by box part, input block, intermediate shaft part, output block and control member constitute, on the input shaft in the input block respectively kink one fast gear is arranged, two-speed gear, three-speed gear also is connected with the oil pump power take-off gear, at two-speed gear and three-speed gear, respectively be provided with synchronizer between one fast gear and the oil pump power take-off gear, and a speed on the input shaft, two-speed and three-speed gear are meshed with corresponding intermediate gear on the intermediate shaft part separately.
Be provided with bi-directional synchronization pushing-type synchronizer between described two-speed and the three-speed gear, and between a fast gear and oil pump power take-off gear, be provided with one-way latch formula synchronizer.
A speed described in the utility model, two-speed and three-speed gear respectively pass through the bearing kink on input shaft, and two synchronizers then directly are connected on the input shaft by spline.
Described synchronizer links to each other with shift fork in the control member by sliding sleeve, and this shift fork links to each other with mechanical type single pole remote operation mechanism.
The utility model compared with prior art, it is steady, brisk, reliable to have gearshift, obviously alleviated manipulator's labor intensity, only limited raising on manufacture cost, and the control system of vehicle has had the raising of matter, has improved the characteristics such as competitive ability of complete machine on engineering market widely.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is transmission principle figure of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: Fig. 1, shown in Figure 2: the utility model is mainly by box part, input block, and intermediate shaft part, output block and control member constitute.It is provided with three gears, promptly by the bearing kink one fast gear 7, two-speed gear 8 and three-speed gear 9 is arranged on the input shaft 6 of input block 2, when neutral, exists relative rotation speed between above-mentioned three gears and the input shaft 6; On input shaft, also be equipped with oil pump power take-off gear 10 in addition.The utility model is provided with bi-directional synchronization bevel-type synchronizer 11 between two-speed gear 8 and three-speed gear 9, be provided with one-way latch formula synchronizer 12 between a fast gear 7 and oil pump power take-off gear 10, and described synchronizer directly is fixed on the input shaft by spline.The utility model must be thrown off the main clutch between motor and the speed changer earlier before putting into gear; When putting into gear, stir the synchronizer upper sliding sleeve by the shift fork in the control member 5, utilize remaining geared speed and the awl dish conjugation in the synchronizer, making needs the gear of transmission and the relative rotation speed between synchronizer progressively to eliminate, promptly reach synchronous, thereby make sliding sleeve shift to the soldered tooth cover of gear end by an end of synchronizer easily, but the moment of torsion that transmits on the input shaft passes to each respective gears by synchronizer, finally by intermediate shaft part 3, the respective gears in the output block 4 is exported each the corresponding output torque after speed change.
The utility model adopts mechanical type single pole remote operation mechanism, and it links to each other with described synchronizer sliding sleeve by the shift fork in the control member 5, and realizes controlling.
The utility model is in order to solve when the neutral lubrication problem of each gear support bearing on the input shaft, the spy is provided with lubricating pump, this oil pump is a double discharge pump, the characteristics of double discharge pump are that turning to of turnover fluid direction and rotatingshaft is irrelevant, turn to regardless of prime mover, the oil inlet and outlet of pump is all constant, no matter the power direction of input end is contrary just, oil pump can guarantee that all each bearing provides pressure lubrication on the input shaft like this.Other structure in the diagram is same as the prior art, to one skilled in the art, all can be on top of, this paper is not described in more detail.
