Problems solved by technology

[0002] In the prior art, the drive axle is composed of axle housing, wheel reduction mechanism, wet brake, half shaft, and main reduction mechanism. The internal structure of the wet brake is simple, and the brake does not have a wear indicator rod that cannot indicate the situation of safe use. There is only one track inside the brake. The O-ring is sealed, and there is no cooling chamber for the friction plate. The O-ring will wear and leak oil under long-term operation. The temperature of the friction plate is high without cooling, which will cause serious wear of the friction plate, low braking reliability, and short service life. High use and maintenance costs

Embodiment Construction

[0019] Below in conjunction with embodiment, further illustrate the present invention.

[0020] see figure 1 It can be known that a scraper wet brake drive axle of the present invention is composed of a wheel speed reduction mechanism 1, a wet brake 2, a half shaft 3, a main transmission assembly 4, and an axle housing 5. The wheel speed reduction mechanism 1 The outer splines of the wheel casing 6 on the upper wheel are connected with the inner splines of the dynamic friction plate 21 inside the wet brake 2, the wheel wet brake assembly is fixed on the axle housing 5 through a hollow shaft and stud bolts, and the main transmission assembly 4 passes through The stud bolts are fixed on the axle housing 5; the wheel side reduction mechanism 1 and the main transmission assembly 4 are connected through the half shaft 3.

[0021] see figure 2 , image 3 It can be seen that the wet brake 2 is fixed on the axle housing 5 through the hollow shaft, the hub housing and the ring gear...

Abstract

The invention discloses a wet brake drive axle of a scraper. The drive axle comprises a hub reduction mechanism, a wet brake, a half axle, a main drive assembly and an axle housing. The wet brake is provided with a brake shell, a brake spring is arranged in the brake shell and makes a piston cover pressed on a brake piston ring, the brake cover is connected with a fixed static friction plate, a movable friction plate is arranged on the position corresponding to the static friction plate, a connection groove is formed in the outer side of the brake cover, and a floating seal is arranged in the connection groove; a planetary wheel is disposed on the hub reduction mechanism and fixed to a planetary wheel frame through a planetary wheel shaft; a sun gear is fixed to the half axle, the sun gear drives the planetary wheel and the planetary wheel frame to rotate around the sun gear, the planetary wheel frame is fixed to a hub shell through bolts, and the planetary wheel frame drives the hub shell to rotate. The friction force between the movable friction plate and the static friction plate is reduced, the service life is improved, the structure is simple, and the use and maintenance cost is low.

Description

technical field [0001] The invention relates to transmission, travel and braking systems in engineering machinery, in particular to a scraper wet brake drive axle. Background technique [0002] In the prior art, the drive axle is composed of axle housing, wheel-side reduction mechanism, wet brake, half shaft, and main reduction mechanism. The internal structure of the wet brake is simple, and the brake does not have a wear indicator rod that cannot indicate safe use. There is only one track inside the brake. The O-ring is sealed, and there is no cooling chamber for the friction plate. The O-ring will wear and leak oil under long-term operation. The temperature of the friction plate is high without cooling, which will cause serious wear of the friction plate, low braking reliability, and short service life. The use and maintenance costs are high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a scraper wet brake...
