Description
Technical field
The invention belongs to hydraulic construction machine technical field, particularly a kind of hydraulic pressure energy consuming brake ceasing shake for road roller vibrations wheel fast.
Background technique
Existing vibration type road roller also exists vibrations work and stops after shock driving wheel under effect of inertia, still continue to rotate the phenomenon of a period of time, and the shortcoming of this breath shake overlong time, have impact on the performance of equipment and the travelling comfort of operator.Also do not cease shake method fast preferably at present.We have invented a kind of hydraulic pressure energy consumption braking principle and structure to overcome the quick breath shake device of above-mentioned defect.
Summary of the invention
The object of the invention is to the shortcoming improving vibration type road roller breath shake overlong time, a kind of hydraulic pressure energy consuming brake for the quick breath shake of road roller vibrations wheel is provided.
Technological scheme of the present invention is as follows:
The vibrations principle of vibration type road roller is that the pressure oil exported by hydraulic-pressure pump drives oil hydraulic motor to drive vibrations wheel rotate and realize.When the work of vibrations stops, vibrations wheel still rotates in continuation under the effect of inertial force, drive oil hydraulic motor to rotate conversely because vibrations wheel coaxially connects with oil hydraulic motor, make motor be converted to the role of oil hydraulic pump, just as motor is converted to generator under powered attendant-controlled wheelchairs driving.Oil hydraulic pump after conversion and mechanical damping load (dynamic braking valve) to link together composition one oil hydraulic circuit (see fundamental diagram) by we, define one and utilize hydraulicdriven energy consumption braking system.When road roller stops vibrations, selector valve returns meta, and A mouth is disconnected with T mouth with P mouth with B mouth (see accompanying drawing 1): oil hydraulic motor (6)-A mouth-dynamic braking valve (5)-B mouth is connected the closed hydraulic drive circuit (see figure 2) of formation one.Oil hydraulic motor (6) is now converted to hydraulic pump under the driving of vibrations wheel (16) inertial force, this oil hydraulic pump (oil hydraulic motor 6) pressure oil liquid that continuation rotation exports under the driving of vibrations wheel (16) inertial force flows through A mouth (or B mouth) and directly acts on the steel ball (12) of dynamic braking valve, steel ball (12) jack-up pressure head (13) overcomes the resistance of damping spring (14), become low pressure oil behind the gap forcing the hydraulic oil of high pressure to flow through between steel ball (12) and one-way valve seat (11) to flow back to B mouth (or A mouth) for oil hydraulic pump (oil hydraulic motor 6) and continue fuel feeding.Flowed friction is passed to oil hydraulic pump (oil hydraulic motor 6) when flowing through the gap between steel ball (12) and one-way valve seat (11) by fluid, rotational resistance is passed to vibrations wheel (16) by transmission shaft (15) by oil hydraulic pump (oil hydraulic motor 6) again that be subject to flowed friction, by the mode that this flowed friction transmits and changes, shake the inertia energy consumption of wheel (16) the most at last on dynamic braking valve (5), thus make vibration type road roller reach the effect of breath shake fast.
Advantage of the present invention is: the present invention highly shortened the breath shake time of road roller vibrations wheel, improves equipment performance and that operator are worked is more comfortable, embodies the social progress that people-oriented.Particularly: 1) breath shake successful.2) the breath shake time is controlled.3) structure is simple.4) course of action is reliable.

Embodiment
The invention belongs to vibration type road roller stops quick breath during vibrations work to shake system, and it is that the rotatory inertia mechanical energy of vibrations wheel is converted to hydraulic energy by driving oil hydraulic pump (oil hydraulic motor 6), consumed fast by hydraulic energy and make vibration type road roller cease a kind of novel working principle of shake fast and former road roller control valve and dynamic braking valve are designed all-in-one-piece structure by the damping of dynamic braking valve 5 pairs of running of hydraulic power oils.
Its structure is as shown in drawings: the oil hydraulic circuit that dynamic braking valve 5 and oil hydraulic motor 6 form is that oil hydraulic motor 6-A mouth-dynamic braking valve 5-B mouth is connected the closed hydraulic drive circuit of formation one.Oil hydraulic motor 6 is now converted to the role of oil hydraulic pump under the driving of vibrations wheel (16) inertial force, this oil hydraulic pump (oil hydraulic motor 6) pressure oil liquid that continuation rotation exports under the driving of vibrations wheel 16 inertial force flows through A mouth (or B mouth) and directly acts on the steel ball 12 of dynamic braking valve, steel ball 12 jack-up pressure head 13 overcomes the resistance of damping spring 14, force the hydraulic oil of high pressure to flow through steel ball 12 and one-way valve seat (to become low pressure oil behind the gap between 1 to flow back to B mouth (or A mouth) for oil hydraulic pump (oil hydraulic motor 6) and continue fuel feeding, flowed friction is passed to oil hydraulic pump (oil hydraulic motor 6) when flowing through the gap between steel ball 12 and one-way valve seat 11 by fluid, rotational resistance is passed to vibrations wheel 16 by transmission shaft 15 by oil hydraulic pump (oil hydraulic motor 6) again that be subject to flowed friction, by the mode that this flowed friction transmits and changes, shake the inertia energy consumption of wheel 16 the most at last on dynamic braking valve, thus make vibration type road roller reach the effect of breath shake fast.Dynamic braking valve 5 in parallel is connected to selector valve 1 with oil hydraulic motor 6 one end, and the other end is connected on selector valve 24, and selector valve 1, selector valve 24 control by solenoid directional control valve 2.Frequency adjustment valve 1 controls the speed of vibration frequency.
