Description

The dismounting erecting by overhang of automobile gearbox

The utility model relates to the improvement of automotive service set, specifically is a kind of dismounting erecting by overhang of automobile gearbox, and it belongs to the auto repair technical field.

In automobile maintenance industry, for the maintenance of large-scale truck, especially at dismounting clutch, flywheel, gear ring when changing clutch friction plate or changing release bearing, all needs gate-type to hang pulley, transmission assembly is hung out car body, abdicate service clearance, could keep in repair clutch.Lifting after maintenance finishes also quite bothers.This maintenance work will have three people's cooperatings at least, just can finish, and its operating condition and labour intensity are all abominable, its inefficiency, and the employee operates dangerous.

The purpose of this utility model is the dismounting erecting by overhang that a kind of automobile gearbox will be provided, and replaces the above-mentioned transmission assembly that hangs out, and abdicates the operational method of service clearance.Utilize the car body self-condition, design a kind of isolated plant.Under the prerequisite that does not shift out gearbox, gearbox is hung in dismounting, moves it relative room, parts such as convenient for maintaining clutch.

Task of the present utility model is finished by following technical scheme, developed a kind of dismounting erecting by overhang of automobile gearbox, it is installed between the maintenance square hole and automobile chassis crossbeam on automobile cab floor, in this square hole, hang balladeur train by being erected at this floor openings along last " π " shape, sliding being hung in two fixing holes on gearbox input end face top; The hand braking plate wheel of this case output is solid on the tractive screw rod by tractive ring flange hinge, and the other end of this bar then by the balance adjustment hook, is hung under the automobile chassis crossbeam.

Described " π " shape is hung balladeur train, and it includes: " π " shape is striden frame, two touch panel legs, and two are hung solid hole leg and two and hang slide bar; Wherein " π " shape two ends screw thread of striding frame connects the intrinsic touch panel leg that has regulating handle, two these legs are erected at this floor openings respectively along last, two solid hole legs that hang that extend below in this square hole are separately fixed on two termination bolts of hanging slide bar by stomidium on this leg and nut thereof, the other end of two these slide bars screw thread respectively is fixed in the corresponding screw on the engine output housing end face, sliding sleeve has two fixing holes on gearbox input end face top respectively on the sliding polished rod of two these slide bar middle parts, and then constitutes gearbox input cunning and be hung in " π " shape and hang hanging on the slide bar of balladeur train.

Described balance adjustment hook, it comprises: be fixed on the load-bearing hinge frame below this crossbeam, the hinged vertical screw of this hinge frame screw thread is connected on the control fork hook plate, and cunning is embedded with adjusting nut in the hook strips groove of this hook plate, this nut thread is engaged on the tractive screw rod, also is fixed with adjusting handle on this bar.

Its effect of dismounting erecting by overhang of the present utility model is: hang the part deadweight that sledge slide hangs the gearbox input owing to be located at the cab floor hole along last " π " shape, can make this case hang the middle part of slide bar, and steadily safety is slided.The part deadweight of gearbox input is to stride frame and touch panel supporting leg part of bearing on the floor thereof by " π " shape, again by the two ends bolt of hanging slide bar be separately fixed at hang on the leg of solid hole and engine output housing end face on, and bear another part.Gearbox moves axially a segment distance like this, but constant axial location.Gearbox leaves this section of engine output shell ends space, has facilitated the maintenance clutch operating.The deadweight of the part of gear box output end is by the solid balance adjustment hook of tractive screw rod institute screw thread hinge, hangs to be born under the automobile chassis crossbeam.Because having designed adjusting nut cunning that the tractive screw flight cooperates is embedded in the hook strips groove on the control fork hook plate, the driving that is fixed on the adjusting handle on this bar is arranged again, gearbox is moved in the horizontal axis balance, be beneficial to maintenance employee operating maintenance, bring great convenience to maintenance work.The vertical screw that is connected in addition on the control fork hook plate is hinged on the load-bearing hinge frame by screw thread, can regulate gearbox equally in vertical direction and be equilibrated on the former horizontal axis.Whole maintenance work can be finished by people's handled easily, does not need to be regardless of working environment with the trench that repairs, and just can finish the maintenance work to the clutch running part, and its operating efficiency is excellent.

Embodiment of the present utility model further specifies as follows in conjunction with the accompanying drawings:

Fig. 1 is the schematic diagram of the dismounting erecting by overhang user mode of automobile gearbox.

Make the gearbox dismounting erecting by overhang that a cover is used for Dongfeng brand EQ140 type truck referring to Fig. 1.It is installed between the maintenance square hole 11 and automobile chassis crossbeam 12 on automobile cab floor 10.In this square hole 11, hang balladeur train by being erected at these 10 holes, floor along last " π " shape, sliding be hung in gearbox 13 input end face tops two in the fixing hole 23.The deadweight of gearbox 13 inputs is hung balladeur train by " π " shape and is applied on the cab floor 10.The hand braking plate wheel 15 of these case 13 outputs connects intrinsic tractive ring flange 4 by bolt 16, and is solid on tractive screw rod 9 by these dish 4 hinges again.The other end of this bar 9 is then by balance adjustment hook, the automobile chassis crossbeam of hanging 12 times.The deadweight of gearbox 13 outputs is exactly solid at the balance adjustment hook by 9 screw threads of tractive screw rod hinge, hangs on automobile chassis crossbeam 12 times, is born the output deadweight of gearbox 13 by this beam 12.

Designed " π " shape of this dismounting erecting by overhang is hung balladeur train and included: " π " shape is striden 17, two of 2, two touch panel legs of frame and is hung solid hole leg 18 and two and hang slide bar 1.Wherein, the two ends screw thread that " π " shape is striden frame 2 connects intrinsic touch panel leg 17, two these legs 17 that have regulating handle 3 and is erected at these 10 holes, floor respectively along last, and regulates the support height that " π " shapes are striden frame 2 by regulating handle 3.Two solid hole legs 18 that hang that extend below in this square hole 11 are separately fixed on two termination bolts of hanging slide bar 1 by stomidium 19 on this leg 18 and screw thread 20 thereof.The other end of two these slide bars 1 screw thread respectively is fixed in the corresponding screw 22 on the engine output housing end face 21, can make like this gearbox 13 input end face tops two on fixing hole 23 slide over respectively on the sliding polished rod of two these slide bar 1 middle parts, and then gearbox 13 is moved on this slide bar 1 middle part, the input cunning that constitutes gearbox 13 is hung in " π " shape and hangs hanging on the slide bar 1 of balladeur train.
