In order to facilitate understanding of the low-temperature heating device for a rubber bushing provided in the embodiment of the present application, an application scenario of the low-temperature heating device for a rubber bushing provided in the embodiment of the present application is first described. The rubber bushing low-temperature heating device comprises a rubber bushing, wherein the rubber bushing is arranged on the outer side of the rubber bushing, and the rubber bushing is arranged on the outer side of the rubber bushing. The following detailed description is given with reference to the accompanying drawings and examples.
Referring to fig. 1 to 3, a rubber bushing low-temperature heating device provided in an embodiment of the present application includes a heating device 40, a sensor, and a controller 80. The heating device 40 is a functional device for heating the rubber bushing. The sensor is used as a detecting device for detecting the current state of the rubber bushing, and the controller 80 is used for controlling the heating device 40 to heat the rubber bushing according to the data detected by the sensor, so as to adjust the state of the rubber bushing in different states. The above-described structures will be described below.
First, the structure of the rubber bushing is described, and the rubber bushing is composed of a nested multi-layer structure, which includes a bushing inner tube 20, a rubber body 10, and a bushing outer tube 50 in sequence from inside to outside. The bushing inner tube 20, the rubber body 10 and the bushing outer tube 50 are connected together by vulcanization of the entire rubber body 10 between the bushing inner tube 20 and the bushing outer tube 50. The bushing outer tube 50 is generally made of steel, aluminum or nylon, the main rubber is made of natural rubber or chloroprene rubber, and the bushing inner tube 20 is made of aluminum or steel.
The heating device 40 is arranged in the rubber bushing and is fixedly connected with the rubber bushing. Specifically, the heating device 40 is fixed in the bushing inner tube 20 of the rubber bushing. Wherein the heating means 40 includes a case fixed in the rubber bushing, and a heating coil 30 fixed in the case. Specifically, the heating coil 30 is a resistance coil 30, the resistance coil 30 is made of a copper material, and the housing body is a hollow cast aluminum housing. The resistance coil 30 is clamped into the housing body or adhesively fixed in the housing body by means of an adhesive. In addition, one end of the housing is provided with a notch for the lead wire of the resistance coil 30 to protrude.
When the heating device 40 is fixed to the rubber bushing, the housing is in interference fit with the rubber bushing; or the shell is connected with the rubber bushing in an adhesive mode. Specifically, the housing and the inner pipe 20 of the bushing are in interference fit connection, the interference is generally 0.05mm to 0.2mm, and a small gap of 0.05mm to 0.1mm can also be adopted to be fixedly connected through bonding of an adhesive.
Referring to fig. 4 together, the rubber bushing low-temperature heating apparatus provided in the embodiment of the present application further includes a power supply device for supplying power to the heating device 40. For example, the power supply device CAN supply power to a CAN bus of the whole vehicle. Specifically, the lead of the resistance coil 30 extends through a notch of the housing of the heating device 40 and is connected to the vehicle CAN bus through a power supply line. The resistance coil 30 is powered by the CAN bus.
The preparation method of the heating device 40 and the rubber bushing comprises the steps of carrying out main body rubber vulcanization on the bushing inner tube 20 and the bushing outer tube 50 on a rubber vulcanizing machine according to the existing bushing processing technology to form a rubber bushing body, then carrying out interference press fitting on the bushing heating device 40 or fixing the bushing heating device 40 to the inner side of the bushing inner tube 20 through an adhesive, extending a power supply line out of a clamping groove of the bushing inner tube 20, and connecting the power supply line to a finished automobile wiring harness after loading. And will not be described in detail herein.
When heating the rubber bushing, heating device 40's principle is through around the environment that rubber used, increases artificial heating system, heats the rubber bushing system under the winter environment in the north, avoids arousing the sclerosis of rubber material itself because of low temperature to in the vehicle use, reduce because relative motion leads to the rubber and the metal structure friction of sclerosis to produce low temperature abnormal sound. Because the size of the bushing is small, the space for installing the heating device 40 is limited, so the technical proposal of the resistance coil 30 is adopted, and the heating control is carried out by utilizing the principle that the metal coil 30 generates heat due to resistance after being electrified. The heating calculation formula power is equal to the square of the voltage divided by the resistance, i.e., P ═ U)/R, where the voltage value U is the voltage of the CAN bus and the resistance value R is the actual measurement value of the heating coil 30.
When the rubber bushing is heated, the control is carried out through a corresponding control method. Specifically, when the room temperature value is lower than the set value, for example, when the vehicle is parked for a long time in a low-temperature environment and then is started in a cold state, the ECU controls the heating device 40 to heat, and controls the heating system to be closed after the temperature is increased to a certain time, so that the problem of low-temperature abnormal sound of the rubber can be avoided, and high-temperature aging damage caused by overhigh heating temperature of the rubber can be avoided. The control principle is explained in detail below.
The sensors of the low-temperature heating device for the rubber bushing provided by the embodiment of the application comprise two sensors, namely a temperature sensor 60 and a time sensor 70; among them, the temperature sensor 60 is used for the temperature sensor 60 that detects the ambient temperature of the vehicle, and the time sensor 70 is used for detecting the parking time of the vehicle. The above-mentioned ambient temperature of the vehicle and the parking time are two key factors affecting the hardening of the rubber bushing. In the embodiment of the application, the hardening condition of the rubber bushing is determined according to the ambient temperature of the vehicle and the parking time, and the heating degree of the rubber bushing is determined according to the ambient temperature of the vehicle and the parking time.
To facilitate control of the heating degree of the rubber bushing, the controller 80 provided in the embodiment of the present application is configured to control the power supply time of the power supply device to the heating device 40 according to the ambient temperature of the vehicle detected by the temperature sensor 60 and the parking time of the vehicle detected by the time sensor 70. Namely, the heating degree of the rubber bushing is controlled according to the ambient temperature of the vehicle and the parking time.
When the rubber bushing is heated, whether the rubber bushing needs to be heated is judged firstly, namely whether the environment temperature of the vehicle is lower than a first set temperature is judged firstly, and when the environment temperature is lower than the first set temperature, the vehicle is determined to be in a cold state and the rubber bushing needs to be heated. When the ambient temperature is greater than or equal to the first set temperature, it is determined that the vehicle is not in a cold environment, and the rubber bushing does not need to be heated. Therefore, in the concrete control, the controller 80 is configured to control the time sensor 70 to detect the parking time of the vehicle when the ambient temperature of the vehicle detected by the temperature sensor 60 is less than the first set temperature. That is, whether the rubber bushing needs to be heated is judged first, and when the rubber bushing needs to be heated is determined, the influence of the parking time on the hardening degree of the rubber bushing is considered. The first set temperature can be different temperatures such as 10 degrees to-30 degrees, and can be determined according to the actual vehicle running environment.
The controller 80 is specifically configured to control the power supply device to supply the electric energy to the heating device 40 for a first time when the vehicle environment temperature detected by the temperature sensor 60 is greater than a second set temperature and less than the first set temperature, and the parking time of the vehicle detected by the time sensor 70 is greater than or equal to the first set time; wherein the second set temperature is less than the first set temperature. Specifically, when the outdoor temperature is lower than 4 ℃ (the second set temperature) and higher than the first set temperature T1, if the vehicle dead time is greater than or equal to the first set time a, the heating is stopped after the first time B1.
The controller 80 is specifically configured to control the power supply device to supply the electric energy to the heating device 40 for a first time when the vehicle environment temperature detected by the temperature sensor 60 is less than the second set temperature and greater than the third set temperature, and the parking time of the vehicle detected by the time sensor 70 is less than the first set time; wherein the third set temperature is less than the second set temperature. Specifically, when the outdoor temperature is lower than the second set time T1 and higher than the third set time T2, if the vehicle dead time < the first set time a, the heating is stopped after the first time B1.
The controller 80 is specifically configured to control the power supply device to supply the electric energy to the heating device 40 for the second time when the vehicle environment temperature detected by the temperature sensor 60 is less than the second set temperature and greater than the third set temperature, and the parking time of the vehicle detected by the time sensor 70 is greater than or equal to the first set time; wherein the first time is less than the second time. Specifically, when the outdoor temperature is lower than the second set temperature T1 and higher than the third set temperature T2, if the vehicle stagnation time is greater than or equal to the first set time a, the heating is stopped after the second time B2.
The controller 80 is specifically configured to control the power supply device to supply the electric power to the heating device 40 for a second time when the ambient temperature of the vehicle detected by the temperature sensor 60 is less than the third set temperature and the parking time of the vehicle detected by the time sensor 70 is less than the first set time. When the outdoor temperature is lower than the third set temperature T2, if the vehicle dead time < the first set time a, the heating is stopped after the second time B2.
The controller 80 is specifically configured to control the power supply device to supply the electric power to the heating device 40 for a third time when the vehicle environment temperature detected by the temperature sensor 60 is less than a third set temperature and the parking time of the vehicle detected by the time sensor 70 is greater than or equal to the first set time; wherein the third time is greater than the second time. When the outdoor temperature is lower than the third set temperature T2, if the vehicle stagnation time is greater than or equal to the first set time A, the heating is stopped after the third time B3.
The specific control strategy of the above heating modes can be referred to table 1.
