Problems solved by technology

[0003] If the brake calipers and brake discs used on road vehicles are used for the braking of mining dump trucks, the high temperature generated by continuous braking during driving can easily cause thermal decline of the brake calipers and brake discs. And the brake disc is prone to high temperature due to long-term friction, and the high temperature is likely to cause fire in the hydraulic pipeline near the brake caliper and brake disc. Hidden danger

Embodiment Construction

[0033] The following description illustrates specific embodiments of the invention sufficiently to enable those skilled in the art to practice and reproduce it.

[0034] Such as figure 1 Shown, is the use state diagram of oil-cooled multi-disc service brake of mining dump truck in the present invention; figure 2 Shown is the position diagram of the service brake 4 in the drive axle in the present invention.

[0035] The tire 2 of the mining dump truck is installed on the wheel hub 1, and the wheel hub 1 is installed on the driving axle. Between the frame 3 and the hub 3.

[0036] When the mining dump truck is braked, the service brake 4 acts on the wheel hub 1 with braking torque to limit the rotation speed of the wheel hub 1, and the rotation speed of the tire 2 is also limited, finally realizing the deceleration braking of the mining dump truck.

[0037] Such as image 3 Shown, is the installation sectional view of service brake 4 in the present invention; As Figure 4...

Abstract

The invention discloses an oil-cooled multi-piece type driving brake of a mining dump vehicle. The oil-cooled multi-piece type driving brake comprises a piston shell body, a piston, a gear ring, a drive gear, a backboard, a sealing shell body, a hub adaptor, an oil sealing shell body, a spring, a friction piece and a distance piece. A power cavity is defined by the piston shell body, the gear ring, the drive gear and the backboard, and the piston, the spring, the friction piece and the distance piece are arranged in the power cavity. The invention further discloses an assembly of the oil-cooled multi-piece type driving brake of the mining dump vehicle. The oil-cooled multi-piece type driving brake of the mining dump vehicle is used for the assembly of the oil-cooled multi-piece type driving brake of the mining dump vehicle. Braking force is large, the performance is stable, and the oil-cooled multi-piece type driving brake and the assembly of the oil-cooled multi-piece type driving brake are especially suitable for the large-tonnage mining dump vehicle.

Description

technical field [0001] The invention relates to a mining dump truck, in particular to an oil-cooled multi-plate service brake of a mining dump truck and an assembly thereof. Background technique [0002] Mining dump trucks are used in various open-pit mines for ore transportation. The self-weight and load of mining dump trucks are huge. During the transportation process, there are many long-distance continuous uphill and downhill roads. Mining dump trucks need frequent braking. [0003] If the brake calipers and brake discs used on road vehicles are used for the braking of mining dump trucks, the high temperature generated by continuous braking during driving can easily cause thermal decline of the brake calipers and brake discs. And the brake disc is prone to high temperature due to long-term friction, and the high temperature is likely to cause fire in the hydraulic pipeline near the brake caliper and brake disc. Hidden danger. Contents of the invention [0004] The te...
