Integracija ohišja zavornega bobna v kolesni elektromotor

Ostrouška, Martin (author), Klemenc, Jernej (mentor)

V diplomskem delu smo iskali konstrukcijsko rešitev za pritrditev kolesnega elektromotorja na zavorni boben. Pri izdelovanju konceptov smo morali upoštevati temperaturne raztezke, ki se pojavijo kot posledica povečane temperature po sunkovitem zaviranju vozila, ter ob tem zagotavljati prenos navora iz elektromotorja na zavorni boben in obratno. Za vrednotenje konceptov smo izvedli numerično termo-mehansko analizo in analitični preračun. Pokrov elektromotorja z bobnom povezuje osem vijakov, ki prenašajo napetosti zaradi termičnih raztezkov. S tremi vzmetnimi zatiči pa zagotavljamo prenos navora med elektromotorjem in zavornim bobnom ter obratno.

• Title: Integration of drum brake housing into in-wheel electric motor

Abstract

In the thesis we designed a solution for fixing an in-wheel electric motor to a brake drum. When designing the concepts temperature expansions were considered, which occur due to increased temperature after breaking, while providing torque transfer from electric motor to drum brake and vice versa. Design concepts were validated using a numercial thermo-mechancial analysis and analytical calculations. Electric motor is fixed on brake drum with 8 bolts that take over stresses due to thermal expansions. With three slotted spring pins a transfer of torque from the electric motor to the brake drum and vice versa is assured.
