Embodiment Construction

[0021] The invention provides a wet brake drive axle, which includes an axle housing assembly 3, a wet brake 2 placed in the axle housing assembly 3, a main reducer assembly 1 for the central transmission of the whole axle, and a wheel side reducer assembly 5. One end of the half shaft 4 is connected to the main reducer assembly 1, and the other end is connected to the sun gear 52 of the wheel reducer assembly 5. The power is transmitted to the wheel reducer assembly 5 through the main reducer assembly 1, and after being decelerated by the wheel reducer assembly 5, the power is output by the wheel hub 55. It should be noted that the drive axle is a symmetrical structure centered on the main reducer assembly 1, figure 1 1 only shows the structure of one side of the final reducer assembly 1 to clearly show the specific composition and connection relationship.

[0022] The main reducer assembly 1 is supported by the main reducer housing 11, the main reducer housing 11 is connect...

Abstract

The invention discloses a wet brake drive axle. The wet brake drive axle comprises a main speed reducer assembly, an axle shell assembly, a wet brake positioned in the axle shell assembly, a rim speed reducer assembly and a half shaft, wherein the two ends of the half shaft are respectively connected with the main speed reducer assembly and the rim speed reducer assembly; and when the wet brake is in a brake working state, the half shaft is braked. The wet brake drive axle, provided by the invention, adopts the braking of the half shaft to realize the braking operation; and when the braking operation is performed, a piston pushes a friction pair to perform the pressing and the bonding so as to reliably realize the braking of the half shaft. The wet brake drive axle brakes the half shaft with smaller torque, is small in volume, light in load, low in inertia, simple in structure, large in lubricating oil cavity and excellent in cooling effect, largely reduces the braking heat, and thus effectively improves the working stability and the braking stability of a whole machine.

Description

technical field [0001] The invention relates to a drive axle, in particular to a wet brake drive axle. Background technique [0002] As we all know, the operating conditions of construction machinery are relatively harsh. At present, the domestic construction machinery axle product market is still dominated by dry brake drive axles, and dry drive axles use external dry brakes, which causes dry The type drive axle is greatly affected by environmental factors such as humidity, freezing, sand and dust, the braking performance is unstable, and the service life is short; the wet brake is built-in, basically not affected by environmental factors, the service life is long, and the braking is safe and reliable. It has been widely used in existing construction machinery. [0003] In the prior art, wet brake drive axles have been used in many applications. For example, the Chinese patent document with publication number CN201010184823.6 discloses a "wet brake drive axle and a loader ...
