Description

Semi-automatic speed variable sliding gear shifting box

The utility model relates to the gearbox that motor vehicle use.

The just necessary often gear shift of requirement that motor vehicle are in operation and need overcome various different road drivings, when variable block, must earlier depress clutch pedal while not only but also pull the speed change handle with hand, therefore the driver is very busy, especially just more bother in order to save a gasoline, driver is very tired, but also accelerates the additional wear of clutch transmission, flexible when using in order to improve Motor Vehicle, alleviate driver's the amount of labour again, the utmost point needs existing motor vehicle gearbox is tried every possible means to improve.

The purpose of this utility model is to provide a kind of need not step on clutch pedal through improved gear shift, as long as unclamp throttle, pulls the speed change handle with regard on the required gear of the careless swap-in of energy with hand; Need sliding fuel-economizing, can realize sliding automatically so a kind of semi-automatic speed-change sliding energy-saving safe gearbox as long as throttle unclamped.

The purpose of this utility model is finished by the following technical programs.Semi-automatic speed-change sliding energy-saving safe gearbox, form by housing, loam cake, input shaft, countershaft, pto, follower, interlocking sliding gear collar, manipulating handgrip, speed change handgrip etc., it is characterized by: input shaft one end is designed to the power output constant mesh gear that one is become in the follower weldering that passes through of super-clutch type, and the engine power axle connects countershaft constant mesh gear and pto.

Above-mentioned design proposal proposes in order to realize the purpose of this utility model.Safer changeable again flexible in order to handle, be that a cover can be by the driver-operated mechanism that can realize semi-automatic speed change fully.As long as for example in the time need moving or with dragging anti-driving motor and when free wheel device lost efficacy, drawing manipulating handgrip, just become rigid construction, revert to non-automatic formula mechanical gear box again at once with the counter of motor do.This novel gearbox of motor vehicle dress, owing to realize sliding semi-automatic speed change automatically, oil-saving effect is fine, the urban road fuel saving ratio can reach 5～8%, rural road 8～9%, long-distance unloaded average out to 11.6%.And can also prolong clutch working life more than 3～5 times; because so so it has recoil that the function of unidirectional transmission can protect motor and transmission part to avoid driving wheel hits also and can reduce unnecessary wearing and tearing; life-saving; realize semi-automatic speed change and sliding automatically, improve the gearbox life time so significantly reduce the gearshift number of times again.

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 is a structural representation.

Mark among the figure: 1, input shaft; 2, front bearing retainer; 3, fore bearing; 4, safety interlocking gear; 5, dissolved pillar; 6, interlocking sliding gear collar; 7, handle shift fork; 8, manipulating handgrip; 9, follower; 10, power output constant mesh gear; 11, speed change handgrip; 12, four, five retaining shift forks; 13, four, five retaining sliding gear collars; 14, gear shifter shaft; 15, two, three retaining sliding gears; 16, the sliding gear that reverses gear; 17, pto; 18, loam cake; 19, housing; 20, bearing; 21, output flange; 22, countershaft; 23,24, gear; 25, reverse gear; 26, three retainings; 27, five retainings; 28, countershaft constant mesh gear; 29, countershaft fore bearing; 30,31, needle bearing.

As shown in the figure: the input shaft 1 of power, its end is the star-wheel body, has groove on periphery, dress roller 5 in the groove; Front bearing retainer 2, fore bearing 3, safety interlocking gear 4 all are positioned at the front portion of pto 17; Roller 5 is contained in and reaches in the star wheel groove between the follower 9 interior circles.Interlocking sliding gear collar 6 is positioned at follower 9 outsides, realizes automatic and non-automatic selection with it.Handle shift fork 7 and connect mutually, with its control interlocking sliding gear collar 6 with interlocking sliding gear collar 6.Manipulating handgrip 8 is selected function of use by the driver according to travel situations.In aggregates of power output constant mesh gear 10 and follower 9 seam by this, are given countershaft constant mesh gear 28 with the transmission of power of motor.It comes conversion rate speed change handgrip 11 usefulness, to satisfy the driving requirement.Four, five retaining shift forks 12, four, five retaining sliding gear collars 13 all connect mutually with gear shifter shaft 14, and gear shifter shaft is contained on the pto 17, plays gear location self-locking action.Two, three retaining sliding gears 15, sliding gears 16 that reverse gear are installed on the pto 17; The pto 17 of gearbox is except that being equipped with various gear sliding gears, output bead 21 also is equipped with in its rear end, also be equipped with the different gear of the various numbers of teeth on the countershaft 22, as: five retainings, 27, three retainings 26, reverse gear 25 etc., countershaft fore bearing 29, needle bearing 30,31 are contained in the connection place of pto 17 and input shaft 1, play the location and guarantee concentricity.That is to say and persuade power output constant mesh gear 10 and follower 9 to be coupled as one, be combined as a whole star-wheel, its periphery is gone up fluted, and roller 5 is housed in the groove, and with pto 17, follower 9 consists of automatic free wheel device again.Follower 9 and constant mesh gear 10 seam are given the countershaft constant mesh gear 28 of countershaft 22 and countershaft 22 front ends motor input transmission of power, again through each retaining gear with transmission of power to wheel.

The utility model is simple in structure, only on the basis of existing non-automatic gearbox, increase by seven parts in addition, especially the original production technology of manufacturer and production line not being needed to transform and just can satisfy the new product production requirement, is that other accessory of original gearbox can also not utilize and can cause waste product again.To the non-automatic formula gearbox of original use vehicle, this model utility is installed need not changes primary car structure function (performance), more can not produce a bit destruction, mainly be to have increased new function and effect, use more convenient flexible.
