Design of Oil Pump for T158 Transfer Case
Gášek, Martin ; Jakubec, Josef (referee) ; Dvořáček, Jiří (advisor)
This master’s thesis deals with a new design of an oil pump for Tatra T158 transfer case. The new solution should replace earlier involute internal gear pump which is not able to provide sufficent lubrication. The main problem of the old design is a poor suction at low speeds of the vehicle. Gerotor type of the pump has been chosen. Its main advantages are a convenient specific flow rate and good volumetric efficency. In an analytic calculation of the pump gearing also important functional parameters have been checked, like a pressure angle, flow rate, flow irregularity, specific flow rate, specific slipping. A design with and without axial clearance compensation is introduced. Measurements on a test rig confirmed good suction ability even in low revs. Generated flow rate and pressure are improved. That is a good prerequisite for faster assembly of transfer case with no testing of each oil pump. The tests have not revealed any unexpected wear of parts of the pump so far. It is supposed an application of the new gerotor design in a serial production of T158 truck and other types in the future.
Coupling PTO (POWER TAKE - OFFS)
Holubec, Martin ; Jakubec, Josef (referee) ; Kaplan, Zdeněk (advisor)
This thesis deal with a calculation and a construction concept of a PTO coupling used in Tatra vehicles. The coupling allows turn on an accessory machinery when the engine is on. It is designed as an multiplate clutch with a wet surrounding. The operating is managed by a pneumatic system. The construction solution was restricted mainly by space needs. The calculation includes torque issues and aslo a part considering a heat question. The construction section includes individual clutch parts design.
Investment Construction in the Frame of the Regional Development
Zmrhalová, Adéla ; Jakubec, Josef (referee) ; Hrabincová, Dagmar (advisor)
The goal of the diploma thesis is to describe the issues of structural and regional policies of European Union in the Czech Republic and to create general knowledge about running of drawing financial resources from EU funds for a particular project from an applicant´s perspective. The theoretical part deals with the origins of European Union and formation of regional policy of EU. Afterwords it is focused on the formation of regional policy in the Czech Republic and the project cycle. In practical part the project cycle is applied on a particular project Enlargement of nursery schools in Jihlava – Nursery school Nad Plovárnou 5, Jihlava from setting the targets, applying for the grant and up to the realization of the project itself.
Investment Construction in the Frame of the Regional Development
Zmrhalová, Adéla ; Jakubec, Josef (referee) ; Hrabincová, Dagmar (advisor)
The goal of the thesis is to create a general knowledge about function of regional policy of European Union in the Czech Republic and about drawing of financial resources from EU funds for a particular project. The introduction describes the concept of European Union and the formation of regional policy. In addition, it describes regional policy in the Czech Republic and the project in general. The practical part describes the project of Revitalisation of the pond in Čenkov by Třešť from setting the targets, applying for the reguest of subsidy, up to implementation, termination and final use.
