Abstract
The utility model discloses a wheel mounted disk-shaped arresting gear for rolling stock, comprising a pair of ring-shaped brake disk which is provided outside with brake pads, a group of lever-type clamp mechanism, and a checking cylinder which is provided with an automatic adjusting device for adjusting clearance between the brake pads. The brake disk is fixed on two sides of wheel spokes through bolt fasteners, a friction surface is arranged outside the brake disk, a mounting surface and radiating ribs are arranged inside the brake disk, and the checking cylinder is an air-actuated checking cylinder. After compressed air enters the checking cylinder, a cylinder rod of the checking cylinder is extended out, and the lever-type clamp mechanism is utilized for pressing the brake pads on the brake disk friction surface, thereby braking running rolling stock.
Description
The present invention relates to a kind of wheel mounted disc brake device that is used for rail vehicles.
The brake mode of the existing rolling stock of China mainly contains two kinds, i.e. wheel tread braking and axle-mounted disc brake.Before a kind of mode be to utilize brake shoe to be pressed on the wheel tread to produce friction drag to have come brake action, its shortcoming is the abrasion of having quickened wheel, fricative heat energy makes wheel crack, peel off etc.Though the second way has overcome the shortcoming of first kind of mode, can only be contained in bogie truck has on the car in bigger space, generally can't adopt the axle-mounted disc brake mode for the power truck that gear case, motor are housed on the axletree.
Wheel mounted disc brake device of the present invention is made of a pair of ring-type brake disc, one group of brake pad, one group of lever-type clamp mechanism and an aerobraking cylinder.Brake disc bolt up spare is fixed on the wheel spoke both sides, and its outside is a friction face, and the inboard is an attachment face, is provided with radiating ribs at attachment face.Lever-type clamp mechanism and brake cylinder hanger are contained on the truck frame.After brake cylinder fed pressurized air, the piston rod of brake cylinder stretched out, and promoted lever-type clamp mechanism brake lining is pressed on the brake disc friction face, thereby operating rolling stock is implemented braking.The present invention has the advantage of disc braking, because brake disc is installed in the wheel spoke both sides, does not take the axletree space, therefore is applicable to the various kinds of vehicles bogie of car, especially power truck.The design of brake disc attachment face has radiating ribs, helps heat radiation; Axle-mounted brake disk is subjected to the restriction of vehicle gauge of the locomotive, and friction radius is smaller, and takes turns the brake disk mounted space, spoke both sides that makes full use of, and friction radius is bigger than axle-mounted disc brake.
Concrete structure of the present invention is provided by following drawings and Examples:
Fig. 1 is a wheel mounted disc brake schematic representation of apparatus of the present invention
In the drawings, 1-railroad train wheel, 2-wheel is brake disk mounted, 3-brake lining, the unit brake cylinder of 4-strap brake sheet automatic gap adjustment device, 5-lever-type clamp mechanism.
The embodiment of the invention 1:
Battery-driven car group with running velocity 200km/h is an example, and wheel mounted disc brake device of the present invention (shown in Figure 1) has been installed on the power car bogie truck of these motor train unit.The wheel mounted disc brake device is to realize the motor train unit braking like this.When motor train unit need glancing impact, control system is to part 4 unit brake cylinders input pressurized air, the piston rod that makes unit brake cylinder is to overhanging, impeller 5 lever-type clamp mechanisms, and part 3 brake linings of drivening piece 2 brake disc both sides are pressed on the brake disc friction face, produce friction drag between brake disc and brake lining this moment, and this friction drag is exactly the braking force that makes the motor train unit braking.
Claims (1)
1, a kind of wheel mounted disc brake device that is used for rail vehicles, it is characterized in that: comprise a pair of ring-type brake disc, the arranged outside of brake disc has brake lining, one group of lever-type clamp mechanism, and brake cylinder that has the brake lining automatic gap adjustment device, said brake disc bolt up spare is fixed on the wheel spoke both sides, the brake disc outside is a friction face, the inboard is for attachment face and have radiating ribs, brake cylinder is the aerobraking cylinder, after brake cylinder feeds pressurized air, brake cylinder piston rod stretches out, and brake lining is pressed on the brake disc friction face by lever-type clamp mechanism, operating rolling stock is implemented braking.
