Abstract

Sepeda motor merupakan alat transportasi yang paling digunakan oleh masyarakat di Indonesia. Sistem pengereman pada suatu alat transportasi memiliki peran yang sangat penting untuk memperlambat laju kendaraan.Teknologi sistem pengereman berkembang sangat pesat,hal ini berujuan tentunya agar meningkatkan tingkat keamanan bagi pengguna kendaraan baik itu pengemudi maupun penumpang.Teknologi semacam ABS yang dapat berfungsi sebagai pencegah roda terkunci saat ini menjadi hal standar di dunia transportasi,begitupun dengan teknologi combined brake system yang merupakan fitur yang cukup membantu.Namun teknologi untuk menghindari kegagalan sistem pengereman akibat temperature berlebih pada brakefluid masih belum banyak dikembangkan.Maka dari itu pada penelitian ini dilakukan studi eksperimen pada kinerja komponen active cooling with combined braking sistem.
Pada penelitian ini dilakukan pengujian menggunakan peralatan yang dibuat sesuai dengan literatur yang tersedia,penelitian ini dilakukan dengan tiga ekspresimen untuk mendapat suatu hasil guna untuk perancangan dari active cooling with combined braking sistem,yang pertama adalah mencari pengaruh active cooling with combined braking sistem terhadap temperatur dan brakefluid,dimana brakefluid akan dididihkan pada temperatur yang mendekati titik didihnya, pada penelitian ini didapat pengaruh temperatur terhadap eksistensi vaporlock,kedua mencari pengaruh active cooling with combined braking sistem terhadap temperatur dan koefisien gesek,dimana pada brakepad akan diberi pembebanan untuk menekan disc sehingga mencapai temperatur yang ditentukan,hasil yang didapat dari penelitian ini adalah pengaruh temperatur

terhadap koefisien gesek dan ketiga mencari durability komponen sistem pengereman yaitu seal piston caliper,dimana pada penelitian ini seal akan direbus di dalam panci berisi brakefluid dan di panaskan hingga titik didih brakefluid secara berulang ulang,hasil yang didapat dari penelitian ini adalah pengaruh temperatur terhadap stiffness seal.
Pada penelitian yang telah dilakukan didapat data bahwa pada pengujian pengaruh temperatur terhadap brakefluid,massa brakefluid pengalami penurunan hal ini menunjukkan bahwa adanya perubahan massa dari brakefluid menjadi gas nilai pengurangan massa pada suhu 1900C berkisar antara 0.2 hingga 0.6 gram sedang pada suhu 2600C didapat pengurangan massa sebesar 0.8 hingga 1.6 gram.Pada pengujian pengaruh temperatur terhadap koefisien gesek didapat hasil bahwa semakin panas temperatur maka koefisien geseknya akan semakin kecil hal ini dibuktikan dengan semakin jauhnya jarak pengereman seiring dengan panasnya suhu brakefluid yang diberikan,dari hasil pengujian didapat bahwa pada suhu 148,80C memerlukan jarak pengereman 58 hingga 70 meter sedang pada suhu 1750C membutuhkan jarak pengereman 95 hingga 103 meter.Pada pengujian pengaruh temperatur terhadap stiffness seal didapat hasil bahwa semakin tinggi temperatur brakefluid maka stiffness sealnya akan semakin tinggi hasil yang didapat pada spesimen 1 dengan suhu 1900C 17,82 hingga 19,55 kg/mm sedang pada suhu 2600C 19,87 hingga 22,94 kg/mm sedang pada spesimen 2 dengan suhu 1900C 14,79 hingga 15,37 kg/mm dan pada suhu 2600C 19,99 hingga 20,53 kg/mm.

Motorcycles are the most used means of transportation by people in Indonesia. The braking system on a means of transportation has a very important role in slowing down the vehicle. The braking system technology is developing very rapidly, this is of course aimed at increasing the level of security for vehicle users, both drivers, and passengers. currently a standard thing in the world of transportation, as well as the combined brake system technology which is quite a helpful feature. active cooling components with a combined braking system. In this study, testing was carried out using equipment made in accordance with the available literature, this research was carried out with three expressions to get a useful result for the design of the active cooling with combined braking system, the first is to find the effect of active cooling with combined braking system on temperature and brake fluid, where the brake fluid will be boiled at a temperature close to its boiling point, in this study the effect of temperature on the existence of the vapor lock was obtained, secondly looking for the effect of active cooling with combined braking system on temperature and coefficient of friction, where the brake pad will be given a load to press the disc so that it reaches the temperature determined, the results obtained from this study are the effect of temperature on the coefficient of friction and the third is looking for the durability of the braking system component, namely the piston caliper seal, wherein this study the seal will be boiled in a pan containing brake fluid. d and heated to the boiling point of the brake fluid repeatedly, the results obtained from this study are the effect of temperature on seal stiffness. In the research that has been carried out, it is found that in testing the effect of temperature on the brake fluid, the mass of the brake fluid has decreased, this indicates that there is a change in mass from brake fluid to gas. 0.8 to

1.6 grams. In testing the effect of temperature on the coefficient of friction, the results show that the hotter the temperature, the smaller the coefficient of friction, this is evidenced by the longer the braking distance along with the heat of the given brake fluid temperature, the test results show that at a temperature of 148.80C requires a braking distance of 58 to 70 meters while at a temperature of 1750C requires a braking distance of 95 to 103 meters. In testing the effect of temperature on the stiffness of the seal, the results show that the higher the temperature of the brake fluid, the higher the stiffness of the seal. men 1 with a temperature of 1900C 17.82 to 19.55 kg/mm while at a temperature of 2600C 19.87 to 22.94 kg/mm while specimen 2 with a temperature of 1900C 14.79 to 15.37 kg/mm and at a temperature of 2600C 19.99 to 20.53 kg/mm. The appropriate temperature to be able to determine the most efficient performance of the active cooling with a combined braking system is at 1750C. Where at this temperature is the temperature which is the maximum temperature before the symptoms of braking function failure occur. At this temperature, the change in mass of brake fluid to gas will also have a value. which is smaller than the results obtained where the smaller the temperature, the smaller the mass change that occurs. At this temperature, the change in stiffness of the seal becomes smaller in value because the temperature value will increase with the given temperature. If the test is carried out at least at a temperature 1900C has a maximum change in the value of 1.37 kg / mm, so if at 1750C it will have a smaller change value so that the stiffness seal has a longer life.
