Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
Referring to fig. 1 to 6, in a first aspect, the present invention provides a soft start method for a compressor of an automotive air conditioner, including the following steps:
s1, driving a wear-resistant clutch of the compressor to rotate through a soft starting device of the automobile air conditioner compressor;
specifically, the soft starting device of the automobile air-conditioning compressor comprises an automobile engine driving wheel 7, two driven wheels 8, a belt 9 and a clutch driving wheel 10, wherein the belt 9 is sleeved on the outer side wall of the automobile engine driving wheel 7 and the outer side wall of the driven wheels 8, and the clutch driving wheel 10 is arranged on the outer side wall of the belt 9.
S2, acquiring the loading working condition of the wear-resistant clutch to obtain starting time and starting load;
specifically, as shown in fig. 2, a left drawing in fig. 2 is a conventional clutch, and a right drawing in fig. 2 is a wear-resistant clutch provided by the present invention, the wear-resistant clutch includes a rotating disc 1 and a friction plate 2, the rotating disc 1 has a magnetism isolating groove 3, and the friction plate 2 is fixedly connected with the rotating disc 1 and is located at one side close to the magnetism isolating groove 3; the rotating disc 1 is further provided with a mounting hole 4, a first magnetism isolating through hole 5 and a second magnetism isolating through hole 6, the mounting hole 4 is located at the circle center of the rotating disc 1, the first magnetism isolating through hole 5 is located on one side, close to the mounting hole 4, of the magnetism isolating groove 3, the second magnetism isolating through hole 6 is located between the first magnetism isolating through hole 5 and the friction plate 2, and the aperture of the second magnetism isolating through hole 6 is larger than that of the first magnetism isolating through hole 5. Through automobile engine action wheel 7 rotates and drives belt 9 rotates, belt 9 drives two when rotating from driving wheel 8 with clutch drive wheel 10 rotates, drive when clutch drive wheel 10 rotates wear clutch rotates, realizes the operation of compressor, wear clutch is through reducing magnetism separating groove 3 and increase friction disc 2 width are in order to reach the electromagnetic force unchangeable and the wearability is good.
S3, controlling the gradient step rise of the voltage of the wear-resistant clutch based on the starting time and the starting load to obtain the voltage gradient rise condition;
voltage step-up mode: for example, the starting voltage was increased by 1V per second at 4V, starting at 4V, and increased to 12V within 8s, after which it stabilized at 12V. The gradient of the step in the stage is 1V/S, and different speeds should correspond to different slopes. Curves with slopes compiled from formulas are also suitable for use in this patent.
Specifically, the voltage rises by 2V at preset time intervals until the voltage reaches a preset voltage value; the preset voltage value is 12V.
S4 the wearable clutch performs step pull-in based on the voltage and the voltage slope rising condition.
Specifically, before the voltage reaches a preset value of pull-in voltage, the wear-resistant clutch enters a semi-clutch state; and after the voltage reaches a preset attracting voltage value, the abrasion-resistant clutch performs step attraction based on the condition that the voltage slope rises.
The specific step suction mode is as follows: 1. the starting time is set through software control, and the starting time is at the initial stage of step rising, and the starting time must correspond accurately, if the starting time is too early, the voltage at the starting point is too low, which causes skidding, and if the starting time is too late, the voltage is stepped to be higher, which still generates larger impact, and can not achieve practical significance. In the design, the voltage of a starting point needs to be adjusted to be 4V-6V, and the clutch is in a half-clutch state under the voltage of the starting point. Under the state, the voltage rise and the synchronous pull-in of the clutch are realized.
When the wear-resistant clutch of the compressor receives a starting instruction sent by the whole vehicle, the electrifying voltage is as shown on the left side of fig. 3, and the direct electrifying waveform diagram of the conventional compressor clutch is as shown on the right side of fig. 3. The pull-in of the wear-resistant clutch works in a half-clutch state before the pull-in voltage reaches the designed pull-in voltage, the transmission of torque is soft, so the impact torque is small, the test torque form is as shown in the left side of a figure 4, the right side of the figure 4 is a conventional starting form, and the starting torque reduction range is 10% -50% after the scheme is adopted. The voltage is realized by adopting a mode of controlling a step power supply by software, and the step slopes are different corresponding to different rotating speeds and working conditions. The magnitude of the attraction force is proportional to the attraction voltage.
The conventional compressor is switched ON and OFF by adopting voltage ON/OFF, the power device is directly electrified, the suction and the instant generation of large current are easy, and particularly in the process of starting with a load, the current is 2-4 times as high. The resulting torque demand is increased by a factor of 2 to 4. The invention adopts a soft start method of the automobile air conditioner compressor, and breaks through the traditional scheme that the compressor is directly electrified and started. The invention proportionally outputs the voltage by controlling a software program, thereby realizing the increase of the output of the voltage according to a certain proportion and amplitude, and realizing the gradual increase of the power supply current by controlling the gradual increase of the voltage. In this process, surge currents and surge torques are avoided. However, if a conventional clutch is used for soft start, the clutch is easy to ablate, so the wear-resistant clutch is matched with the wear-resistant clutch. The wear-resistant clutch is required to be gradually sucked in the relative slipping process, and ablation is avoided.
The impact torque is small when starting is required. The effects of the following three factors are:
1. the larger the starting speed, the larger the impact torque;
2. the smaller the starting time gradient is, the smaller the impact torque is;
3. the smaller the load is, the smaller the impact torque is at the time of starting;
the better the slip resistance of the clutch, the smaller the slope of the start time and the larger the speed at start and the larger the load at start.
Therefore, the slope should be adjusted in conjunction with the operating conditions (speed and load at start-up). The decision criterion for the adjustment is that the slope is as low as possible and the clutch is not ablated by slip.
The invention carries out brand new design on the magnetic circuit of the wear-resistant clutch, the main design part is used for adjusting the quadrupole magnetic circuit on the suction surface, the material of the friction plate 2 is selected, and the material of the friction plate 2 is any one of a semimetal type friction material, a composite fiber friction material and a ceramic fiber friction material. Meanwhile, the time and the speed of the suction are designed in a matching way, and the longer the sliding time is, the faster the relative speed during the suction is, and the more easily the sliding ablation is generated. Therefore, the slip resistance/start time slope/speed at start/load at start of the clutch need to be matched, and the matching of the four is not enough, and after the soft start method of the automobile air conditioner compressor and the matched wear-resistant clutch are adopted, the scheme realizes that the highest torque reduction rate can reach 50-60 percent, as shown in figure 5. The actual test results are shown in FIG. 6.
Referring to fig. 7, in a second aspect, the present invention provides a soft start device for an automotive air conditioner compressor, including a driving wheel 7 of an automotive engine, two driven wheels 8, a belt 9 and a clutch transmission wheel 10, wherein the belt 9 is sleeved on outer side walls of the driving wheel 7 of the automotive engine and the two driven wheels 8, and the clutch transmission wheel 10 is disposed on an outer side wall of the belt 9.
Specifically, the system further comprises a set of power supplies for supplying power to the clutch, and a set of software control program for controlling the power supply. A set of torque acquisition system monitors the torque of the rotating shaft in real time. The belt 9 is driven to rotate by the rotation of the driving wheel 7 of the automobile engine, the two driven wheels 8 and the clutch transmission wheel 10 are driven to rotate when the belt 9 rotates, and the wear-resistant clutch is driven to rotate when the clutch transmission wheel 10 rotates, so that the operation of the compressor is realized.
Although the present invention has been described with reference to the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
