Background technology
Power takeoff all will be installed on heavy dump truck, heavy special-use vehicle to be taken out the power of change-speed box to realize various purposes.For the rear-end power takeoff device (there are input, output gear in inside) of joining on the market the various output torque >=600Nm of change-speed box at present, on change-speed box, install and all take split mounting structure, its installation step is as follows: 1) power takeoff assembly is taken apart to (disintegrating); 2) power takeoff housing (or power takeoff base plate) is connected on the mounting hole of change-speed box with 6 or more bolt; 3) gear, bearing and various annex are arranged on to power takeoff housing (or on power takeoff base plate); 4) power takeoff lid (or power takeoff housing), gear, bearing, flange and annex are arranged on to power takeoff housing (or on power takeoff base plate).The design of above-mentioned split mounting structure has following shortcoming in when assembling: 1) large, the effort, time-consuming of installation workload; 2) to workman's assembly technical requirement high (if installation is bad, product easily being caused to earlier period damage); 3) because split trim designs makes that product structure is large, Heavy Weight, cost be high.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: the power takeoff of the integral installation on a kind of heavy-duty automotive speed changer aft end face is provided, and it is simple in structure, easy for installation, lower to workman's assembly technical requirement.
The power takeoff of the integral installation on heavy-duty automotive speed changer aft end face described in the utility model, comprise power takeoff housing, input gear and output gear are installed in power takeoff housing, it is characterized in that: corresponding input gear is provided with four input end mounting holes on the auxiliary-drive casing body wall of its surrounding is thick, in two outsides, power takeoff housing middle part, be respectively arranged with the first ear seat and the second ear seat for connecting, on the first ear seat, offer the first tie bolt hole, on the second ear seat, offer the second tie bolt hole.
The quantity of above-mentioned input end mounting hole and ear seat, can determine according to the power takeoff of different size, as long as can meet transmission requirement; During fabrication, its material can be cast iron, cast steel and cast aluminium to above-mentioned power takeoff housing; Above-mentioned mouth mounting hole is through hole, and 4 bolts are directly connected to whole power takeoff on change-speed box, and its advantage is to have strengthened widely its Joint strenght.
On wherein said power takeoff housing, corresponding output gear is provided with bearing cap shim, is provided with asymmetric four mouth mounting holes on bearing cap shim, and one of them mouth mounting hole and an adjacent input end mounting hole are overlapping.
During connection, 3 non-overlapped mouth mounting holes are connected to bearing cap shim on power takeoff housing by bolt, and overlapping mouth mounting hole is connected bearing cap shim with power takeoff housing together by bolt with change-speed box, connect safety and stable.This asymmetric connection mode has the following advantages: compared with prior art, make that power takeoff structure is less, cost is lower.
Further, input end mounting hole described in the utility model aperture is 10mm～12mm.
In order to meet the demands, can also reduce cost simultaneously, preferably the thickness of described the first ear seat and the second ear seat is 15mm～40mm, the first tie bolt hole and the second aperture, tie bolt hole are 10mm～12mm.
Further preferred described mouth mounting hole aperture is 10mm～12mm.
Compared with prior art, the utlity model has following beneficial effect:
Pass through the utility model, realized whole trim designs, make it simple in structure, easy for installation, can fit on change-speed box by power takeoff (output torque >=600Nm) integral installation in the situation that not disintegrating assembling is intact and that meet technical requirements, its advantage is: 1) user installation work capacity little, laborsaving, save time; 2) simple not high to workman's assembly technical requirement because assembling, thus the initial quality of product can be guaranteed; 3) because being designed to whole assembling, make that product structure is little, lightweight, cost is low.
