Abstract
The utility model relates to a composite power control device, which comprises a motor, a hydraulic pipeline, a walking valve and a reversing flexible shaft, wherein, the motor is connected with the walking valve through the hydraulic pipeline; and the walking valve is connected with the reversing flexible shaft. The composite power control device is characterized in that the walking valve is connected with an accelerator pressure releasing and regulating valve; the accelerator pressure releasing and regulating valve is connected with one end of a pedal mechanism through a spring; and the other end of the pedal mechanism is connected with an accelerator flexible shaft. The utility model has the advantage that the flow rate of pressure oil can be controlled conveniently, and the magnitude of the output power of an engine can be controlled, so that the influence of the pressure oil on entire car running during reversing is reduced.
Description
Technical field
The utility model relates to a kind of composite power control device, can be used for the control operation that small-sized static pressure loader drives, and improves the utilization rate of engine power, improves the operability of car load, belongs to small-sized static pressure loader technical field.
Background technology
Small-sized static pressure wheel loader is a kind of material shipment (non-) Engineering Work machine that shovels, be widely used in the infrastructures such as city, traffic, water conservancy, be called as " multi-functional mechanical ", special in the construction of new village, small-sized static pressure wheel loader relies on the moderate cost/small and exquisite nimble characteristics of self, is subjected to numerous clients' favor; Particularly be used widely in new countryside construction small building agitator, small-sized sandpit, quartzy factory, coal processing enterprise etc.; Most of small sized loaders on the existing market are machine driving control, and this kind control mode operation labour intensity is big, and it is not too convenient to keep in repair; Drive this type of problem that solved of controlling and use static pressure.As shown in Figure 1, 2, this control system is made up of motor 1, fluid pressure line 2, walking valve 3 and operating mechanism (flexible axle) 4.Walking valve 3 is accepted the pressure oil that pump transmits, control through operating mechanism (flexible axle) 4, realize the commutation of pressure oil liquid, come the CD-ROM drive motor action, realize moving forward and backward of car load with this, this kind control mode is when moving forward and backward mutual conversion work, because the pressure of hydraulic circuit altered course in moment, caused impact, and the handling of car load is descended greatly, sometimes carry out this kind operation under the situation of load having, can cause the flame-out of motor.
Summary of the invention
The purpose of this utility model provides a kind of driving work that can guarantee small-sized static pressure loader, the very convenient flow of controlled pressure oil again, can control simultaneously the size of engine output again, thus the composite power control device of impact when reducing pressure oil liquid when realizing commutation car load walk.
For realizing above purpose, the technical solution of the utility model provides a kind of composite power control device, comprise motor, fluid pressure line, walking valve, commutation flexible axle, motor is connected with the walking valve by fluid pressure line, the walking valve is connected with the commutation flexible axle, it is characterized in that, the walking valve is connected with throttle release control valve, throttle release control valve is connected with pedal gear one end by spring, and the other end of pedal gear is connected with the throttle flexible axle.
The utility model has the advantages that the easily flow of controlled pressure oil, can control the size of the power output of motor simultaneously again, thereby realization reduces the impact of pressure oil liquid to the car load walking when commutating.
Description of drawings
Fig. 1 is the original control device schematic diagram of small-sized static pressure loader;
Fig. 2,3 is a kind of composite power control device structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
Shown in Fig. 2,3, be a kind of composite power control device structural representation, shown a kind of composite power control device is connected with spring 8 by motor 1, fluid pressure line 2, walking valve 3, commutation flexible axle 4, throttle release control valve 5, throttle flexible axle 6, pedal gear 7.
The pressure oil of coming by pump through fluid pressure line 2 to throttle release control valve 5, arrive walking valve 3 through fluid pressure line 2, arrive motor 1 through fluid pressure line again, drive gearbox, when pedal gear 7 rotations, the throttle flexible axle 6 that drive links to each other with it and through spring 8 to throttle release control valve 5 (control crank) action, control crank by throttle release control valve 5, promote 3 actions of walking valve, realize the flow-control of hydraulic oil, by the throttle of throttle flexible axle 6 control motors, realize the power control of motor simultaneously.When turning clockwise, the flow that hydraulic oil enters the work loop increases gradually, the control throttle of motor strengthens simultaneously, power increases, rigidity by spring 8 is closed the drain tap of throttle release control valve 5 fully, by the distortion of spring 8, make throttle flexible axle 6 displacements of control motor continue to increase, the power of motor continues to increase.Be rotated counterclockwise pedal gear 7, it is opposite with said process to load, and carries out switch operation this moment, and pressure oil is by the drain tap oil sump tank of throttle release control valve 5, and gear-change operation can not cause excessive impact.
