Abstract
The utility model discloses a connection structure of a speed changer and a power takeoff, which comprises a speed changer casing, a power takeoff front casing and a power takeoff back casing. The power takeoff front casing and the power takeoff back casing are integrally connected through a connection piece, the speed changer casing, the power takeoff front casing and the power takeoff back casing are connected through a bolt which penetrates through the speed changer casing, the power takeoff front casing and the power takeoff back casing, and a nut is arranged on the bolt. The power takeoff of the connection structure is whole installed on the speed changer, the power takeoff does not need disassembling during installation, installation is convenient, and the power takeoff and the speed changer are reliably connected. Compared with the existing power takeoff, the whole assembled power takeoff is high in assembly efficiency and easy to disassemble and maintain, and greatly improves assembly efficiency and maintenance efficiency. And simultaneously stoppages caused by assembly and disassembly are reduced compared with the power takeoff assembled in a splitting mode.
Description
Technical field
The utility model relates to the connection structure of a kind of change-speed box and power takeoff.
Technical background
On commercial vehicle/comm..vehicles such as dumping car, the power of its hydraulic efficiency pressure system is mainly derived from change speed gear box, and power takeoff is to draw power from change speed gear box, again with the power transmission mechanism of power transmission fuel feed pump.Power takeoff is on change-speed box, to adopt split type installation at present, and the fore shell with power takeoff is installed on the housing of change-speed box earlier, and drive disk assembly and the power takeoff back cover with power takeoff is installed on the fore shell again, and erection procedure is complicated.
Summary of the invention
The technical matters that the utility model will solve is: the connection structure of a kind of change-speed box and power takeoff is provided, makes the easy for installation of power takeoff and change-speed box.
In order to solve the problems of the technologies described above; The utility model comprises gearbox case, power takeoff fore shell and power takeoff back cover; Described power takeoff fore shell and power takeoff back cover link into an integrated entity through attaching parts; Gearbox case, power takeoff fore shell and power takeoff back cover are through running through three's bolted connection, and bolt is provided with nut.
Reliable in order to connect, described power takeoff fore shell and bolt are for being threaded.
Reliable in order to connect, described attaching parts is a bolt and nut component.
The beneficial effect of the utility model is: the integral installation of the utility model power takeoff is on change-speed box, and during installation, power takeoff need not be dismantled, and is easy for installation, and power takeoff be connected with change-speed box firm.This integral body build-up type power takeoff is higher than original power takeoff efficiency of assembling, and quick detachable maintenance has improved efficiency of assembling and maintenance efficiency greatly, has reduced because of the fault of assembling and dismounting causes than separately assembling power takeoff simultaneously.
Description of drawings
Fig. 1 is the main TV structure scheme drawing of the utility model power takeoff;
Fig. 2 is the back view of Fig. 1;
Wherein: 1, power takeoff back cover, 2, power takeoff output shaft end cap, 3, the power takeoff fore shell, 4, bolt, 5, nut.
The specific embodiment
A kind of change-speed box as depicted in figs. 1 and 2 and the connection structure of power takeoff; Comprise gearbox case, power takeoff fore shell 3 and power takeoff back cover 1; Power takeoff fore shell 3 and power takeoff back cover 1 link into an integrated entity through attaching parts; Gearbox case, power takeoff fore shell 3 and power takeoff back cover 1 are connected through the bolt 4 that runs through the three, and bolt 4 is provided with nut 5.Bolt 4 and nut 5 total quadruplets.Be used on the power takeoff fore shell 3 with bolt 4 bonded assembly holes be tapped bore, power takeoff fore shell 3 and bolt 4 are for being threaded.
Power takeoff output shaft end cap 2 is provided with on power takeoff back cover 1, and power takeoff output shaft end cap 2 is used for being connected with oil pump.
Installation method: power takeoff is assembled into one and need not to dismantle assembly.Bolt 4 is connected on power takeoff fore shell 3 and the power takeoff back cover 1 with nut 5; After the power takeoff assembly assembled, the entire package transportation is when needs assemble on change-speed box; Only need down nut 5 dismountings; Be inserted into four bolts 4 in the mounting hole on the case of transmission, install nut 5 again, realize the installation of power takeoff and change-speed box.
