Abstract
The utility model provides an upper cover assembly of an automobile speed changing box, which has technical points as follows: a gear V and VI shifting fork and a reverse gear shifting fork are all mounted on a reverse gear shifting fork shaft, a converting rocker shaft is arranged on the upper cover and sleeved with a gear V and VI converting rocker, the gear V and VI converting rocker can rotate around the rocker shaft, one end of the gear V and VI converting rocker is clamped in a shifting groove of the gear V and VI shifting fork, a gear V and VI converting shifting block is fixed on a gear V and VI shifting fork shaft, and the other end of the gear V and VI converting rocker is clamped in a shifting groove of the gear V and VI converting shifting block. Through the simple converting structure, the sequential gear engagement is realized, no cross influence exists during the time of gear V and VI engagement and reverse gear engagement, an internal gear transmission mechanism of the speed changing box does not need to be changed, the whole processing cost of the speed changing box is lowered, and the upper cover assembly has the advantages of simple structure and facilitation of realization.
Description
Technical field
The utility model relates to a kind of automobile variable speed box cover assembly.
Background technique
At present, the medium-sized gearbox of many retainings that automobile is used is generally put into gear at the high gear sequential of being unrealized when putting into gear, and also is not easy to dismounting and maintenance, and simultaneously, weight is big, is unfavorable for reducing the car load deadweight.
The implication that sequential is put into gear: keep off medium-sized gearbox when putting into gear more; Gear was respectively 1 retaining, 3 retainings, 6 retainings when the driver put into gear forward when manipulation is put into gear; Gear is respectively 2 retainings, 4 retainings, 5 retainings when putting into gear backward, wherein has with driver's manipulation thinking habit in 6 retainings, 5 whens retaining and conflicts, with the world reversed in order of putting into gear; Changing when putting into gear gear into forward is respectively 1 retaining, 3 retainings, 5 retainings, just puts into gear for sequential when gear is 2 retainings, 4 retainings, 6 retainings respectively when putting into gear backward.
Summary of the invention
The purpose of the utility model is to provide a kind of automobile variable speed box cover assembly simple in structure, and five, six retaining shift forks are arranged on the back fork axle simultaneously, puts into gear through the realization conversion sequence formula of setting ahead of installing on five, the six retaining declutch shift shafts.
For this reason; The technological scheme of the utility model is: a kind of automobile variable speed box cover assembly comprises loam cake, back fork axle, one or two retaining declutch shift shafts; Three or four retaining declutch shift shafts; Five or six retaining declutch shift shafts are fixed with five or six retaining guide blocks on five or the six retaining declutch shift shafts, it is characterized in that: five or six retaining shift forks and back fork all are contained on the back fork axle; On cover and be provided with the conversion pitman arm shaft; Five or six retaining conversion rocking arms are enclosed within on the conversion pitman arm shaft; Five or six retaining conversion rocking arms can rotate and change the pitman arm shaft rotation; One end of five or six retaining conversion rocking arms is stuck in the allocating slot of five or six retaining shift forks, on five or six retaining declutch shift shafts, is fixed with one five or six retaining conversion shifting block, and the other end of five or six retaining conversion rocking arms is stuck in the allocating slot of five or six retaining conversion shifting blocks.
Beneficial effect: the utility model is contained in five or six retaining shift forks and back fork on the back fork axle simultaneously; Through stirring piece of five or six retainings; Be delivered on five or the six retaining conversion shifting blocks, and then rotate five or six retaining conversion rocking arms, drive five or six retaining shift forks and put into gear; Finally realize the sequential mode of putting into gear, also guaranteed when hanging five or six retainings (high gear) not go here and there mutually when reversing gear retaining.The utility model is put into gear through simple transformational structure realization sequential, can guarantee that gearbox internal gear driving mechanism need not to change, and has reduced the whole processing cost of gearbox, has advantage simple in structure, that be easy to realize.
Simultaneously, also reduce processing cost, the assembly cost of loam cake, saved link, reduced the weight of last cap assembly, helped reducing the car load deadweight.
