Description
Technical field
The utility model relates to brake equipment, and especially a kind of auxiliary brake of vehicle belongs to machinery manufacturing technology field.
Background technology
Motor vehicle braking system is the guarantee of vehicle safe driving, and the continuous improvement of emergency brake of vehicle system performance becomes the important topic of vehicle design and manufacturing.Emergency brake of vehicle is to make brake facing that wheel hub is produced strong friction by in time exerting pressure at present, and then wheel is stopped operating with gap, until stopping operating fully, and wheel is in the process of slowing down suddenly or stopping operating, wheel and ground produce powerful friction, and the opposition of this friction just makes car speed be minimized up to stopping just.Because vehicle tyre and ground-surface area of contact are limited, the friction that is obtained during emergency brake of vehicle also is limited, therefore, to run at high speed vehicle only the scheme by the friction braking of wheel and ground still be difficult to the braking effect that reaches more satisfactory, accident rate is still higher.
The utility model content
The purpose of this utility model is by setting up complemental brake system, and when increasing emergency brake of vehicle, vehicle and ground-surface area of contact with the bigger reverse frictional resistance of acquisition, stop vehicle as early as possible.
For achieving the above object, technical solutions of the utility model are, the vehicle additional brake composition that is provided includes support, hoist cylinder, brake gear, auxiliary wheel, wherein, support is configured to by crane and auxiliary wheel, described crane is divided into fixed mount and movable frame again, one end of described fixed mount is captiveed joint with vehicle chassis, the other end of described fixed mount is connected with movable frame with hinge or pin mode, auxiliary wheel is installed in auxiliary wheel carrier bottom, the auxiliary wheel wheel hub is provided with brake gear, captive joint with the movable frame of crane in auxiliary wheel carrier top, one end of hoist cylinder is connected with the fixed mount of crane, and the other end of hoist cylinder is connected with the movable frame of crane, described hoist cylinder, the brake piping of brake gear drives executive device with brake and drive system for vehicle with tow and is connected.
The utility model has the advantages that this additional brake is simple in structure, dispose easy for installation, can with the former brake system synchronization action of vehicle, braking maneuver is reliable, can shorten the car brakeing drag effectively, strengthen vehicle safety, also prolonged the service life of vehicle tyre.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model structural representation (left view of Fig. 1).
Fig. 3 is the utility model structural representation (birds-eye view of Fig. 1).
In the above accompanying drawing, the 1st, lifting support movable frame, the 2nd, lifting support fixed mount, the 3rd, auxiliary wheel support, the 4th, auxiliary wheel, the 5th, brake facing, the 6th, hoist cylinder.
The specific embodiment
Below in conjunction with accompanying drawing, introduce an instantiation of the present utility model.
The embodiment that provides is a mounting vehicle additional brake on common six-wheel lorry.In lorry front-wheel and trailing wheel inboard, symmetrical four vehicle additional brakes are set, each vehicle additional brake has two auxiliary wheels 4, and auxiliary wheel is mounted on the bottom of auxiliary wheel support 3, captives joint with the movable frame of lifting support 1 in the top of auxiliary wheel support 3.One end of the fixed mount 2 of vehicle additional brake lifting support is fixed in vehicle chassis, lifting support movable frame 1 is connected with fixed mount 2 by pin, one end of hoist cylinder 6 is fixed in lifting support fixed mount 2, the other end of hoist cylinder then is connected in lifting support movable frame 1, and the pressure oil pipe of hoist cylinder 6 is connected with the motor vehicle braking system oil pressure pump.Brake facing 5 is arranged at auxiliary wheel 4 wheel hub sides in the brake equipment, and air-pressure duct is connected with the air lift pump of motor vehicle braking system in the brake equipment.
When car brakeing, hoist cylinder is under the braking oil pressure effect, action rapidly, the movable frame of lifting support is moved downward rapidly, impel each auxiliary wheel to contact to earth fast, and make each auxiliary wheel hold down certain pressure, the brake equipment of each additional brake also receives the braking pressure from motor vehicle braking system at this moment, each brake equipment promotes brake facing near each auxiliary wheel wheel hub, produces braking force, this moment, formed friction drag between each auxiliary wheel that contacts with ground and ground, friction drag combined action between this friction drag and wheel of vehicle and ground is in the vehicle according to inertia motion, and then makes and be braked vehicle and slow down rapidly, until stopping fully.
In this example, the lifting support fixed mount adopts spring steel plate, and like this, during car brakeing, auxiliary wheel is pressed to ground by hoist cylinder, and this spring steel plate can reduce the impact of rough earth to additional brake.
In this example, can also between the movable frame of the moving bar of hoist cylinder and lifting support elastic telescopicing rod be set, this elastic telescopicing rod also can reduce the impact of rough earth to additional brake.
The increase of additional brake when having increased car brakeing and ground-surface frictional area, and then from having obtained bigger brake resistance, is shortened the vehicle braked drag effectively, has also prolonged the service life of vehicle tyre simultaneously.
