Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings.
[0016] Such as figure 1 and figure 2 As shown, the non-drive axle service brake of the mining rubber-tyred vehicle includes a braking part and a braking indicating part;
[0017] The braking part includes a friction plate 6 and a brake plate 7, and a spring assembly 13 connected to the friction plate 6 and the brake plate 7 through an adjustment pad 8 and a piston 9; the friction plate 6 is connected to the rim 2, so The brake disc 7 is connected to the brake housing 5; the piston cavity where the piston 9 is installed is communicated with the brake oil port 27;
[0018] When braking is required, the pressure oil in the brake oil port 27 is unloaded, the spring assembly 13 presses the friction plate 6 and the brake plate 7 through the piston 9 and the adjustment pad 8, and the friction plate 6 and the brake plate 7 have no relative movement. The friction disc 6 is ...

The invention discloses a service brake of a mining rubber-tyred vehicle dead axle, and belongs to the technical field of mining rubber-tyred vehicle axles. The service brake comprises a braking part and a brake-indicating part. The braking part comprises a friction sheet (6), a brake sheet (7) and a spring assembly (13) connected with the friction sheet and the braking sheet through an adjusting pad (8) and a piston (9). The brake-indicating part comprises an indicating rod (19) connected with the piston through a connecting disc (18). The indicating rod is connected with an adjusting sleeve (20) for adjusting the relative positions of an outer end cover (25) and an indicating port (26). The brake is directly connected with an axle housing to be used as the dead axle, the axle housing needs no mold, weight is reduced, cost is reduced, and benefits are increased. Detaching and mounting are convenient, the friction sheet can be replaced in time, the service life of the brake can be prolonged, and better safety is achieved. Torque is convenient to adjust. The wear condition of the friction sheet can be displayed through the indicating port. The brake can be prevented from continuing to work under the condition that the brake fails through brake failure protection, and potential safety hazards are reduced.
Description
technical field [0001] The invention relates to a service brake, in particular to a service brake for a non-drive axle of a rubber-tyred vehicle for mining, and belongs to the technical field of vehicle axles for a rubber-tyred vehicle for mining. Background technique [0002] Existing mining rubber-tyred vehicles are special vehicles used in mines, and have high requirements for safety performance, especially for braking. Vehicle braking is achieved through axle braking. The axles used in rubber-tyred vehicles are divided into For drive axles and non-drive axles. The drive axle not only bears the load, but also transmits the driving force; therefore, the axle housing of the drive axle has high strength requirements, and the service brakes at the wheel require a large braking torque and safety factor. In order to meet the strength requirements, the bridge housing is mostly welded by cast steel, which is large in size and heavy in weight. In order to obtain a large braking ...
