Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
A kind of device controlling vehicle slow acceleration comprises connecting portion, promotion part, follower, holding part.Wherein, the gas pedal of vehicle is packed on this connecting portion, and the free end of promotion part is fixedly connected with connecting portion, and follower is separately positioned on the two ends of connecting portion and parallel with the free end of promotion part.Holding part is provided with open hollow chamber, in this open hollow chamber, is provided with elastomeric element.One end of each follower to be all slidably mounted in open hollow chamber and to fit with elastomeric element, and holding part is positioned at the same side of follower.Promotion part promotes connecting portion, and then drive gas pedal motion, indirectly can control the aperture of engine air throttle, in experiment, after the speed of a motor vehicle or engine speed reach requirement of experiment, experiment terminates, now promotion part stop motion, follower recoils to initial experimental site, and the speed of each experiment throttle pedal travel is the same, this guarantees the consistance of obtained experimental data in common acceleration noise and vibration experiment.
A kind of embodiment, as depicted in figs. 1 and 2, connecting portion is stationary shaft 1, and the middle part of this stationary shaft 1 offers mounting groove 11, and the gas pedal of vehicle is packed in this mounting groove 11.Connecting portion selects stationary shaft, and structure is simple, and be convenient to processing and manufacturing, in addition, connecting portion also can be designed to cuboid, triangular prism etc.Preferably, the gas pedal of vehicle is fixed in mounting groove 11 through stationary shaft 1 by the first bolt 2, is connected, is convenient to dismounting, improve the operability of this device by the first bolt 2.As shown in Figure 1, promotion part is hydraulic cylinder 3, and in this hydraulic cylinder 3, the free end of piston rod is fixedly connected with the middle part of stationary shaft 1.As shown in Figure 3, the cylinder body of hydraulic cylinder 3 is connected with the fuel tank built with hydraulic pump.Hydraulic cylinder structure is simple, reliable operation.When realizing to-and-fro movement with it, can reduction gear be removed from, and there is no drive gap, stable movement, promotion part also optional motor except selecting hydraulic cylinder.As depicted in figs. 1 and 2, follower comprises fixed support 4 and push rod 5, the middle part of fixed support 4 is separately positioned on the two ends of stationary shaft 1, angle for different vehicle gas pedal is different, the two ends of stationary shaft 1 are packed in the middle part of fixed support 4, and the two ends of the relative stationary shaft 1 in middle part of this stationary shaft 1 are rotatable, so, after adjusting the setting angle of gas pedal and stationary shaft 1, the second bolt 7 is each passed through fixed support 4 and is packed at the two ends of stationary shaft 1 on corresponding fixed support 4.Fixed support 4 passes through bolt-connection with the two ends of stationary shaft 1, both ensure that the firm of connection, and has been convenient to dismounting again.One end of push rod 5 is fixedly connected with one end of fixed support 4, the other end is slidably mounted in the open hollow chamber of holding part 6, this open hollow chamber constitutes and pushes cabin, and the end of this push rod 5 and elastomeric element are fitted, and holding part 6 is positioned at the same side of fixed support 4.The device conveniently controlling vehicle slow acceleration contacts with vehicle body, and the non-openend of holding part 6 is tapered.Further preferably, elastomeric element is volute spring 8, selects volute spring mainly to consider to be convenient to selection, and cheap, in addition, also can select nitrogen spring.For the ease of manufacture, preferably, fixed support 4 and push rod 5 one-body molded.Follower, except selecting said structure, also can select the structure of similar piston rod, or replaces follower and holding part with cylinder.
In Fig. 3, black arrow is the direction of hydraulic coupling, and dotted arrow is running of hydraulic power oil direction.
As shown in figures 1 and 3, when slow acceleration experiment starts, hydraulic pump 3 to be started working in cylinder body pump oil, the effect that piston rod is subject to hydraulic coupling moves right, promote stationary shaft 1 in the process that piston rod moves right to move right, thus driving fixed mount 4 and push rod 5 to move downward pushing compression helical spring 8 in cabin, gas pedal moves downward.At the end of experiment, push rod 5 is subject to the screen resilience of volute spring 8 and the pulling force of gas pedal, thus promotion piston rod gets back to original state, the speed of each experiment throttle pedal travel is the same, this guarantees the consistance of obtained experimental data in common acceleration noise and vibration experiment.
In order to adapt to slow acceleration experiment in various degree, can control the movement velocity of piston rod, mainly through changing the output power of hydraulic pump, wherein a kind of method that changes is the size of current can undertaken by PWM controller in hydraulic control pump output circuit.
