Problems solved by technology

Due to the adoption of this dual-piston brake, the brake device is relatively large in size; and the service brake piston and the parking brake piston each have an independent hydraulic control system, which adopts different oil circuit controls and has a complex structure.
Since the double-acting brake uses spring force for parking braking and hydraulic braking for driving, the two energy sources act independently. In order to fully brake the vehicle, the requirements for the spring are relatively high, and the required hydraulic pressure is large and energy consumption is large. , due to the lack of auxiliary braking, there is a certain safety risk when the power or hydraulic system fails

Embodiment Construction

[0013] From figure 1 It can be seen that the present invention includes a brake and a hydraulic control system. The brake includes a housing cylinder 1, a single piston 2, a friction plate 3, and a power-assisted braking spring 5. The housing cylinder 1 includes a left housing cover 11, The middle housing 12 and the right housing cover 13 are provided with an annular groove 14 in the left housing cover 11. The right end of the middle housing 12 has a through hole 15. The single piston 2 adopts a large annular piston, and its left end is inserted into the left housing cover. In the annular groove 14, the right end passes through the through hole 15 of the middle casing 12 to act on the friction plate 3, and forms a hydraulic chamber with the inner wall of the left casing cover 11 and the middle casing 12, on the single piston 2 An annular outer shoulder 21 is provided, which divides the hydraulic chamber into two separate chambers—brake hydraulic chamber 6 and brake release hyd...

Abstract

The invention discloses an enclosed multi-disc wet type braking device, comprising a hydraulic control system and a brake; wherein the brake comprises a case cylinder body, a single piston and a friction plate, the single piston is arranged in the case cylinder body and one end thereof is acted on the friction plate, the other end of the single piston is opened with a spring hole used for mounting an assisted brake spring, and two hydraulic chambers are formed between the inner wall of the case cylinder body and the single piston, one is a braking hydraulic chamber, and the other one is a releasing hydraulic chamber; and the hydraulic control system comprises a hydraulic control reversing valve and a reverse braking valve, the releasing hydraulic chamber is connected with the outlet of the reverse braking valve and the pilot hole of the hydraulic control reversing valve, and the braking hydraulic chamber is communicated with one hole site of the hydraulic control reversing valve. The braking device of the invention overcomes the defects of the prior art and has the characteristics of safety, reliability, good performance, simple structure, low price, energy conservation and long service life.

Description

technical field [0001] The invention relates to a fully enclosed multi-disc wet brake device. Background technique [0002] At present, the fully enclosed multi-disc wet brake device is widely used, especially in underground trackless mining equipment. It is mainly composed of a hydraulic control system and a brake, and the brake includes dynamic friction plates, static friction plates, pistons, compression Spring and housing cylinder. When in operation, the device mainly controls the hydraulic control system to supply or drain oil to the piston oil chamber in the brake, and pushes the piston to compress or loosen the dynamic and static friction plates, so as to realize the braking or driving of the vehicle. [0003] According to the difference in force exerted by the piston on the dynamic and static friction plates, the brake device is mainly divided into two types: hydraulic brake, spring release or spring brake, hydraulic release, among which: the former mostly adopts a ...
