Abstract
The utility model relates to a braking system for wheeled engineering machinery, particularly to a combined compressed air and hydraulic clipper disk type braking system for wheeled engineering machinery, which comprises an air compressor, a non-return valve and a gas storage tank in pipeline connection. The gas storage tank, a brake pedal and a traveling brake booster pump are in pipeline connection; the gas storage tank, a parking switch and a parking brake booster pump are in pipeline connection; the traveling brake booster pump and three pairs of traveling brakes are in pipeline connection; the parking brake booster pump and one pair of parking brakes are in pipeline connection; two pairs of the traveling brakes are positioned on the front wheel of a vehicle body, and the other pair of the traveling brakes is positioned on the rear wheel of the vehicle body; and the pair of the parking brakes is positioned on the rear wheel of the vehicle body. The traveling brakes and the parking brakes are combined compressed air and hydraulic clipper disk type brakes. The combined compressed air and hydraulic clipper disk type braking system provided by the utility model can brake a vehicle in an emergency case rapidly and reliably, has small brake control force, and is simple and labor-saving in operation. The braking and traveling use the same gas supply system, so as to reduce manufacturing cost of the system.
Description
Technical field
The utility model is a kind of industrial wheeled equipment brake system, particularly a kind of industrial wheeled equipment gas-liquid caliper disc brake system.
Background technology
Existing industrial wheeled equipment brake system, its braking during standstill are normally installed shoe brake or plate disc brake in the output shaft position of change speed gear box, and joystick is installed in operator's compartment, and by the wire rope transfers operating effort.The brake system of this form, its braking force is less, and reliability is relatively poor under ramp Parking and emergency braking situation especially.
Summary of the invention
The purpose of this utility model is in order to overcome existing shoe type or the disk braking system braking force is less, reliability is relatively poor defective, to invent the industrial wheeled equipment gas-liquid caliper disc brake system that a kind of braking force is big, reliability is high.
The purpose of this utility model realizes as follows: described industrial wheeled equipment gas-liquid caliper disc brake system, form by running brake, Parking Brake, brake pedal, Parking switch, service brake booster pump, braking during standstill booster pump, air compressor, storage tank and check valve; Air compressor, check valve and storage tank are connected by pipeline; Storage tank, brake pedal and service brake booster pump are connected by pipeline; Storage tank, Parking switch and braking during standstill booster pump are connected by pipeline; The service brake booster pump is connected by pipeline with running brake; The braking during standstill booster pump is connected by pipeline with Parking Brake.
Described running brake has three pairs, two pairs of front-wheels that are positioned at car body wherein, a pair of in addition trailing wheel that is positioned at car body; Parking Brake has only a pair of, and it is positioned at the trailing wheel of car body.
Described running brake and Parking Brake are the gas-liquid caliper disk brake.
Good effect of the present utility model is as follows: the utility model adopts caliper disk brake and the combined mode of booster pump, and control of braking is carried out in driving and Parking, can in case of emergency carry out rapid failure-free braking to vehicle; The utility model makes and adopts pneumatic mode to implement braking, and its control of braking power is little, and is easy and simple to handle laborsaving, the chaufeur indefatigability; The utility model uses same gas supply system to provide the control source of the gas as Parking and service brake, and manufacturing cost is lower.

The specific embodiment
As shown in Figure 1, described industrial wheeled equipment gas-liquid caliper disc brake system is made up of running brake 1, Parking Brake 2, brake pedal 3, Parking switch 4, service brake booster pump 5, braking during standstill booster pump 6, air compressor 7, storage tank 8 and check valve 9; Air compressor 7, check valve 9 and storage tank 8 are connected by pipeline; Storage tank 8, brake pedal 3 and service brake booster pump 5 are connected by pipeline; Storage tank 8, Parking switch 4 and braking during standstill booster pump 9 are connected by pipeline; Service brake booster pump 5 and running brake 1 are connected by pipeline; Braking during standstill booster pump 6 and Parking Brake 2 are connected by pipeline.
Described running brake 1 has three pairs, two pairs of front-wheels 10 that are positioned at car body wherein, a pair of in addition trailing wheel 11 that is positioned at car body; Parking Brake 2 has only a pair of, and it is positioned at the trailing wheel 11 of car body.
Described running brake 1 and Parking Brake 2 are the gas-liquid caliper disk brake.
In use, when the Parking switch is in the driving gear, pressurized air output is arranged, at this moment the Parking booster pump has pressurized air to enter, and the braking liquid of Parking booster pump is a depressurization phase; When the Parking switch is in the Parking gear, non-compressed air output, at this moment the Parking booster pump does not have pressurized air to enter, and the braking liquid of Parking booster pump is a pressurized state.
In use, when brake pedal is in the release position, non-compressed air output, at this moment braking booster pump does not have pressurized air to enter, and the braking liquid of braking booster pump is a depressurization phase; When brake pedal is operated, pressurized air output is arranged, at this moment braking booster pump has pressurized air to enter, and the braking liquid of braking booster pump is a pressurized state.
