Integral gearbox of road roller

Abstract

The invention discloses an integral gearbox of a rod roller, wherein a box body of the integral gearbox is an integral structure. The box body is provided with a first transmission shaft, a second transmission shaft, a third transmission shaft, a fourth transmission shaft, a gap bridge shaft, a reversible joystick and a speed-change joystick. The first transmission shaft is at least provided with two or more speed-change driving gears with different diameters; the second transmission shaft is provided with a speed-reduction gear, a speed-change passive gear and a speed-change sliding gear, and the speed-change sliding gear is provided with a shift fork which is connected with the speed-change joystick; the third transmission shaft is provided with a speed-reduction passive gear and two reversing active gears; the fourth transmission shaft is provided with two reversion passive gears and a reversion sliding gear, the reversion sliding gear is arranged between the two reversion passive gears and is provided with a shift fork which is connected with the reversible joystick; and the gap bridge shaft is arranged between the fourth transmission shaft and the third transmission shaft and is provided with a gap bridge gear. The integral gearbox of the road roller, disclosed by the invention, has the characteristics of small size, reasonable structure, easiness in manufacturing, low cost, convenience and flexibility in operation and control, and high work efficiency.

Description

technical field [0001] The invention belongs to the technical field of transmission devices for road rollers, and mainly relates to an integral gearbox for road rollers, which is suitable for all large, medium and small tandem road rollers. Background technique [0002] At present, the gearboxes of known various large, medium and small tandem rollers are almost all split structures. Although split gearboxes are more convenient to assemble, they are bulky, complex in structure, difficult to manufacture, prone to oil leakage, poor in versatility, small in scope of use, difficult to process and assemble, high in cost, and inconvenient to maintain. Since the working method is to change the direction first and then change the speed, and the bridge gear is located on the upper part of the box body, it is easy to be difficult or even unable to shift gears, which is not only difficult to operate and control, but also seriously affects the service life of the equipment. Since there ...
