Description
Technical field
The utility model relates to a kind of single-deck brake equipment, and specifically a kind of large-scale electric transmission dumping car back axle single-deck brake equipment, belongs to electric transmission dumping car brake equipment field.
Background technology
At present, the dry plate disc brake of 200 tons of above large-scale mine electric transmission dumping cars of load carrying ability, is generally arranged on the drive motor in rear-axle casing both at home and abroad.Adopt the drive motor of this brake mode need to configure two brake discs, two Parking Brakes and two running brake, conventionally by two brake discs along drive motor main shaft axial array, on each brake disc, configure a running brake and a Parking Brake.In use, find, this brake mode, required parts are many, and manufacturing cost is high, and the installing space needing is large, and the service clearance in rear-axle casing is less, is not easy to maintenance maintenance.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of large-scale electric transmission dumping car back axle single-deck brake equipment, and required parts are less, and installing space is large, are convenient to layout, gap adjustment and the maintenance maintenance of drg.
To achieve these goals, a kind of large-scale electric transmission dumping car back axle single-deck brake equipment that the utility model adopts, comprise brake disc, be arranged on running brake support, the Parking Brake support on drive motor respectively, described running brake support, Parking Brake number of holders are two, on running brake support, by running brake, adjust pad running brake is installed, on Parking Brake support, by Parking Brake, adjust pad Parking Brake is installed, the quantity of described brake disc is one; Two running brake symmetries, two Parking Brake symmetries, and be each other " ten " font and be arranged on brake disc.
Preferably, described brake disc is bolted on motor flange dish.
Further, two described running brake symmetries, two Parking Brake symmetries, and be each other non-" ten " font and be arranged on brake disc.
Single-deck brake equipment of the present utility model, only need on a brake disc, just can arrange two Parking Brakes and two running brake, in the situation that keeping original braking effect, the required parts of brake equipment are installed and be reduced, and parts machining is easily manufactured, reduced productive costs; Adopt the structure of single brake disc, make brake equipment compact overall structure, saved installing space, be convenient to the layout of the interior miscellaneous part of layout, gap adjustment, maintenance maintenance and rear-axle casing of drg.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is birds-eye view of the present utility model;
Fig. 3 is left view of the present utility model.
In figure: 1, running brake support, 2, running brake adjusts pad, 3, running brake, 4, brake disc, 5, motor flange dish, 6, drive motor, 7, Parking Brake support, 8, Parking Brake adjusts pad, 9, Parking Brake.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, a kind of large-scale electric transmission dumping car back axle single-deck brake equipment, comprise brake disc 4, be arranged on running brake support 1, the Parking Brake support 7 on drive motor 6 respectively, described running brake support 1, Parking Brake support 7 quantity are two, on running brake support 1, by running brake, adjust pad 2 running brake 3 is installed, on Parking Brake support 7, by Parking Brake, adjust pad 8 Parking Brake 9 is installed, the quantity of described brake disc 4 is one; Two running brake 3 symmetries, two Parking Brake 9 symmetries, and be each other " ten " font and be arranged on brake disc 4.
As of the present utility model preferred, described brake disc 4 is bolted on motor flange dish 5, and removing and installing of brake disc 4 is more convenient.
During use, single-deck brake equipment is arranged on the rear axle wheel reductor drive motor 6 of dumping car, brake disc 4 is bolted on motor flange dish 5, motor flange dish 5 female spliness link together by spline fitted and drive motor 6 castellated shafts, and carry out axial compression location by motor spline shaft convex shoulder and pressing plate.Two Parking Brake supports 7 are arranged on drive motor 6 by bolt symmetry, and they are respectively Parking Brake 9 and provide support; Two running brake supports 1 are arranged on drive motor 6 by bolt symmetry, and they are respectively running brake 3 and provide support.The quantity of adjusting pad 8 by adjusting Parking Brake, increases or reduces the span between Parking Brake 9, and the friction lining of realizing Parking Brake 9 is identical with the gap of brake disc 4 both sides, reaches matching requirements; By adjusting running brake, adjust the quantity of pad 2, the friction lining that control realizes running brake 3 is identical with the gap of brake disc 4 both sides, reaches matching requirements.After having assembled, by hydraulic efficiency pressure system, realize the switching of drg, reach the mechanical braking to wheel limit drive motor 6.
Single-deck brake equipment of the present utility model, can also adopt two running brake 3 symmetries, two Parking Brake 9 symmetries, and is each other non-" ten " font and is arranged on brake disc 4, also has good braking effect.
This single-deck brake equipment, only need on a brake disc, just can arrange two Parking Brakes 9 and two running brake 3, in the situation that keeping original braking effect, assemble the required parts of brake equipment less, and parts machining is easily manufactured, reduced productive costs; Adopt the structure of single brake disc 4, make brake equipment compact overall structure, saved installing space, and in the layout of drg, gap adjustment, maintenance maintenance and rear-axle casing, the layout of miscellaneous part is all very convenient.
