Background technique
At present, the engineering machinery of domestic production and some special vehicles, still using the mechanical gear shift speed changer greatly, as vibrating roller etc., and they are the Purely mechanical shift transmission basically, its structure composition includes box part, input block, intermediate shaft part, two spindle units, idle pulley parts and control member etc. substantially, adopts the constant mesh gear transmission.The mechanical gear shift speed changer cost of this routine is lower, and reliability and durability.But in use ubiquity following two problems, the firstth, and berth-changing strength is bigger, the gear shift difficulty, operator's labor intensity is big; Second exist in use that " the flutter phenomenon, vehicle is easily lost rank at climb and fall or when meeting obstacle or be out of supply 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 each grade all to have synchronizer, can realize steady, brisk, the reliable automobile-used mechanical gear shift speed changer of gear shift, it is made up of box part, input block, intermediate shaft part, two spindle units, idle pulley parts and control member etc., on two of two spindle units at least kink three forward gears gears and two reverse gears are arranged, every gear all has but list/bi-directional synchronization bevel-type synchronizer, and wherein two idle gears of at least two reverse gears and idle pulley parts mesh respectively.
The forward gears gear that is nested with on described two respectively with jack shaft on intermediate gear engagement, and forward gears gear and reverse gear all by sliding bearing kink separately on two.
Described two at least two reverse gears going up kinks are meshed with at least two disjunctor idle gears, wherein idle gear also with jack shaft on the countershaft-gear that is provided with mesh.
Be fixed with two shaft transmission gears on two output terminals on described two spindle units, be connected in the odd-side parts on the box part, the odd-side axle is provided with the odd-side gear, this odd-side gear meshes by intermediate drive gear and two shaft transmission gears.
The control member that links to each other with each synchronizer is installed on the described box part, and this control member disposes the remote both-way operation of mechanical type single pole mechanism.
The utility model is compared with old-fashioned pure mechanical gear shift speed changer, has property of automatic shft and further improves, and operator's labor intensity obviously alleviates, and the manoeuvring performance of vehicle has had the raising of matter, and versatility is good, and the competitiveness of product in market such as increases greatly at characteristics.
Description of drawings
Fig. 1 is the structural representation of major axis square type of the present utility model.
Fig. 2 is a concentricity output type 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 includes box part 1, input block 2, intermediate shaft part 3, two spindle units 4, idle pulley parts 5, odd-side parts 6 and control member 7.It adopts the constant mesh gear transmission, is provided with third gear forward gears and second gear backward gear, and each grade realized gear shift by synchronizer.Be placed in the casing 11 with bearing after two 41 sockets in input shaft 21 in the input block 2 and two spindle units 4.On casing 11, also by the bearing horizontal jack shaft 31, idler shaft 51 and odd-side axle 61 are arranged separately.Input gear 22 on the input shaft and 32 engagements of the left side gear on the jack shaft 31, and the first order transmission of formation speed changer.By the sliding bearing kink five gears are arranged on two 41 in two spindle units 4, these five gears from left to right are respectively the three-speed gear 42 that advances, the two-speed gear 43 that advances, the fast gear 44 that advances, fall two-speed gear 45, the fast gear 46 that falls.On two 41, be provided with three cover list/bi-directional synchronization bevel-type synchronizers 47 between five gears altogether.The utility model switches between several fast gears with second-speculation's speed ratio transmission before realizing three by synchronizer, at this moment three cover synchronizers are the single-line type synchronizer, as changing synchronizer into reversible, then constitute four preceding second-speculation, wherein fourth speed is a direct high, and two outlet speed ratios are 1: 1.The three-speed gear 42 that advances on two 41, the intermediate gear 33 that is connected on advance two-speed gear 43 and advance a fast gear 44 and the jack shaft 31, right side gear 34 and countershaft-gear 35 mesh respectively.Kink has two idle gears 52 of disjunctor on idler shaft 51, the wherein right side idle gear and fast gear 46 engagements of falling, and the left side idle gear meshes simultaneously with the countershaft-gear 35 and the two-speed gear 45 that falls respectively.Be fixed with on described two 41 output terminal that two shaft transmission gears 48, are connected in the odd-side parts 6 on the box part 1, odd-side axle 61 is provided with odd-side gear 62, this odd-side gear 62 meshes by an intermediate drive gear 63 and two shaft transmission gears 48.Odd-side axle 61 1 sides at odd-side parts 6 also are provided with parking brake 64.
Control member 7 described in the utility model is arranged on the top of box part 1, it includes shift shaft 71 and is nested with on the shift shaft, overlap three groups of shift forks 72 that the sliding sleeve on the synchronizers cooperates respectively with three, and it also disposes the remote both-way operation of mechanical type single pole mechanism.During gear shift, stir sliding sleeve on the synchronizer by shift fork, utilize remaining geared speed and the awl dish frictional engagement in the synchronizer, making needs the gear of transmission and the relative velocity of synchronizer progressively to eliminate, thereby make sliding sleeve shift to the soldered tooth cover of gear end by synchronizer one end easily, allow the moment of torsion of each fast gear transmission on the jack shaft by each the fast gear on synchronizer transmission and corresponding two, finally finish the corresponding moment of torsion of output each after high speed by the odd-side parts.They can make gear shift steady, brisk, reliable, and the feel same with manual gear of vehicle arranged.
Structure shown in Figure 2 and structure shown in Figure 1 and transmission, handle structure are identical, different is that structure shown in Figure 2 does not have the odd-side parts, on two 41 output terminal, directly be fixed with output sleeve 49, because of other structure same as shown in Figure 1, so it is not repeated to introduce in more detail.
