Description

Bulldozer modular transmission mechanism

The utility model relates to the transmission mechanism of bulldozer.

As everyone knows, in the existing bulldozer design, not relatively independent between several big function blocks of bulldozer, interlaced between the functional block structural component.For example: braking in a turn system and central transmission, its casing are the rear axle box welded together with mainframe; Braking in a turn and central transmission agency piece remove fraction such as steering brake, steering cluth can not assemble on main line, the assembling of other part must just can be finished on main line; Whole for another example transmission, the inner housing of this functional block is on rear axle box, semiaxis is supported on chassis bearing diagonal seat and the chassis bearing support, whole transmission is relatively independent on function, but in the assembly and disassembly of parts, its structure but is not relatively independent, on production line, to consume a large amount of time, just can finish the assembling of whole whole transmission, assembling process is relatively disperseed, and is not easy to the packaged quality control of joining in the process of whole transmission agency; And the other parts, go out power apparatus, fluid torque-converter, gearbox as transfer case, though structure is more independent relatively, be connected with universal joint between fluid torque-converter and the gearbox, but they belong to the bulldozer drivetrain components, must parts of parts finish connection between its parts in main line, and the assembly manipulation space is less, be not easy to operation, need spend the plenty of time on main line equally, it is consuming time longer to make that car load is assemblied on the main line.

The purpose of this utility model provides a kind of bulldozer transmission mechanism, makes a few big function block modularized designs.Independently parts are independent on structure design to make function, are convenient to integrated on connecting.

The purpose of this utility model realizes as follows: this bulldozer modular transmission mechanism relates to fluid torque-converter, gearbox, braking in a turn and central transmission, whole transmission, fluid torque-converter, gearbox, braking in a turn and central transmission, whole transmission all has independently casing, fluid torque-converter is connected with casing between the gearbox, gearbox is connected with casing between braking in a turn and the central transmission, be connected by mainframe between the casing of braking in a turn and central transmission and the casing of whole transmission, the power shaft of gearbox is connected with the turbine hub power of fluid torque-converter, output shaft of gear-box is connected with the cone pinion power of braking in a turn and central transmission, and the output shaft of braking in a turn and central transmission is connected with the pinion power of whole running part.The dynamic output device of returning apparatus on the casing of fluid torque-converter.

This bulldozer modular transmission mechanism, independently parts are independent on structure design to make function, on connecting, be convenient to integrated, make the independently bigger module of the integrated back conduct of little module of several functions, forming an integral body is connected with main frame, reduce complete machine between the assembling link on the main line is timely, improve main frame output beat.The parts module design is convenient to management and quality control that parts are produced.Reduce assembling, maintenance and cost of upkeep.Be convenient to intensification and produce, improve the quality of products, reduce production costs.

Below in conjunction with accompanying drawing the utility model is further described.

Accompanying drawing is the structural representation of the utility model bulldozer modular transmission mechanism.

With reference to accompanying drawing, the casing of bulldozer braking in a turn and central transmission 3 is separated from main car frame, this part is designed to one separately, have independently casing, be connected with gearbox 2 as a module, realization is integrated with gearbox 2, and gearbox 2 also has independently casing, and the output spline F of gearbox 2 is connected with the splined hole of the cone pinion G of braking in a turn and central transmission 3.Cancellation is connected in the former universal joint between fluid torque-converter 1 and the gearbox 2, and the power shaft E of gearbox 2 is connected with the turbine D spline of fluid torque-converter 1, realizes the integrated of fluid torque-converter 1 and gearbox 2, and the two forms overall structure.The dynamic output device P.T.O of returning apparatus on the casing of fluid torque-converter realizes the integrated of power output and fluid torque-converter 1.Motor A is connected in fluid torque-converter 1 through damper B and universal joint C with power.Fluid torque-converter 1 forms overall structure with gearbox 2, braking in a turn and central transmission 3 integrated backs, be installed on the supporting seat of main car frame front and back as a bigger module, back mount pad is a split type structure, is convenient to fluid torque-converter 1, gearbox 2, braking in a turn and central transmission 3 and integrally mounts and dismounts on main car frame.Whole transmission 4 is designed to the deceleration of single-stage commutating tooth, single-stage planetary gear reduction, have independent casing, whole transmission 4 becomes independently parts, and casing is connected with mainframe, and the output shaft H of braking in a turn and central transmission 3 is connected with spline form power with the pinion I endoporus of whole transmission 4.In addition, support because the present structure of whole transmission 4 has been cancelled the bearing diagonal and the semiaxis of chassis, need to design pivot in addition on chassis, chassis is connected with main car frame by pivot like this, can realize that the chassis front portion swings up and down around pivot.
