Chassis Design of Off-Road Buggy
Richter, Vojtěch ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This thesis is focused on the front and rear suspension of the off-road buggy. For the front suspension is compared the concept with and without pushrod with respect to the kinematics parameters and the damping parameters. For the rear axle, there are three concepts that is compared, especially multilink suspension, double wishbone, and swing axle. Finally, structural design and dimensioning for front axle is performed.

Buggy Concept Design
Richter, Vojtěch ; Vančura, Jan (referee) ; Blaťák, Ondřej (advisor)
The aim of this bachelor thesis is to create instruction for the construction of a terrain buggy. It’s research of used technology, but there are also key components calculation included. The thesis is divided into five parts. In the first part, there is a research of the components of the racing vehicle and there are some equations for calculation of important parameters. Furthermore, there is layout and dimension of main components and the frame. In this part is also solved storage of the engine in the frame. The third part is devoted to the calculation of the necessary driving force of the vehicle and the parameters of the braking system. The following section discusses the concept of suspension and damping with respect with favourable kinematics of the system.

Compact transmission
Richter, Vojtěch ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This bachelor thesis focuses on compact transmissions. The motive of the thesis is to review modern gearbox concepts. It describes special gearboxes that are compact in design, e.g.: worm gearbox, planetary gearbox. The focus is on the environment in which they operate, the input speed, the magnitude of power transmitted, the weight and dimensions of the gearbox. Machines that can be included in this group and operate with compact gearboxes are aircraft engines, wind turbines, industrial robots or small portable machines and medical devices. The work includes the design of a gearbox for a car winch. It is a three-stage planetary gearbox and 7 variants have been calculated. The required parameters were a maximum gearbox diameter of 100 mm and a minimum thrust of 1500 kg. Furthermore, an electric motor was defined. Subsequently, the best gearbox design was selected with a gear ratio of 1:144, a diameter of 92 mm, a width of 35 mm and a thrust of 1503 kg.
