Opis:
The most important aspect of constructions of vehicles is safety. In motorcycles, in contrast to cars is not common to use elements of passive safety which minimalize consequences of collision. Therefore the most important is to ensure the proper possibility to avoid crash that is the adequate level ofactive safety which is mostly the brake system. It is often assisted by the construction which prevents the wheels to block, however the majority of motorcydes are still not equipped in this kind of system. In order to determine the effectiveness of working of the brake system and its impact on motorcycle 's movement safety, it is necessary tofocus on case of emergency braking, that is delaying, to full stop where important is to reach the maximal possible delay in the shortest period of time. Because of the changes in road surface, important is to be aware of releasing or stopping the motorcycle in different conditions. It permits us to react properly and avoid dangerous situations in case of noticing a surface with different adherence. The purpose of the research is to analyze changeability braking process depending on different surfaces on which the motorcycle is moving. The research was carried out on one motorcycle and four different surfaces, reflecting the conditions of every day use of vehicle. It was dry, wet and destroyed asphalt, and gravel surface. Comparing the value of delay, its process and stability in time, velocity of accumulation and way of braking obtained on different surfaces.

Opis:
The main idea of this article was to compare the results of new design electric brake to the older version of hydraulic brake in laboratory tests. The energy of braking should be very similar due to the same mass of the airplane. That is why the laboratory tests of both brakes were took place in the same stand. Of course, the parameters were similar but not at all. The main idea was to create the solution, which could be used in vehicle like airplane. The electric brakes could replace traditional hydraulic brake solution. The results could be interesting for every researcher who is interested in brakes. Other important idea of this article was to describe the tests of new electric brake prototype. The purpose of the tests was to check designing of electric brakes. The electric brake prototype should ensure sufficient efficiency, safety, reliability and durability during braking, which is required in certification processes and is particularly important when researching innovative solutions. It was really important to verify the design and check the parameters. Of course, there is really important to remember that in every new type of the prototype solutions there are many pros and cons, which are typical only for considered design. Nowadays every electric brake design is different because there is a lot of new concept.

Opis:
The purpose of this article was to show two thing thermal issues theory and thermovision tests in the laboratory. The main idea of this article was to describe the thermal issues theory of interesting problem base on the thermovision tests of new type electric brake prototype. After the creation of new product the designer needed to know how behave the prototype of the brake during tests with higher energy which could increase the temperatures on the object in our case of the electric brake prototype. The first step in that kind of issues was thermal analysis, which is very useful to define and subscribe the thermal issues. The second step it was measurement of the temperature, which was really significant during the electric brake tests. It was really important to check the temperature of engines. If there was some influence to the brake during braking. One of the method was using special thermal camera. The camera was checking the temperature during whole test after beginning the test to the end of the trial. The full spectrum of the temperature allowed the author to verify if there was some influence of temperature to the new electric brake prototype. The thermocouple was other type of sensors, which was normally used in our laboratory methodology to check temperature during the test. The pyrometer was other type of the method, which was used to measure the temperature after the test. The results of this measurement were subscribed in this article.

Opis:
To analyze the braking process of a mine diesel locomotive with hydrostatic-mechanical transmission (HSMT), a mathematical model has been developed. In contrast to available models, this one takes into consideration rules of changes in controlling the parameters of hydrostatic drive (HSD) and implementation methods for the braking process. Moreover, the model makes it possible to study changes in kinematic parameters, power parameters, and energy parameters of HSMT under various conditions of a mine diesel locomotive operation. It has been determined that the use of HSMT operating according to the “output differential” scheme is possible, providing kinematic disconnection of the engine from the driving wheels (for emergency braking with complete stop of the diesel locomotive) or at the expense of HSD while preserving the kinematic connection between the engine and the wheels (for deceleration). Use of the braking system together with HSD or the braking system only while preserving the kinematic connection between the engine and the wheels will result in HSMT failure.

Opis:
A prototype double spring, consisting of the main four-leaf spring and the auxiliary two-leaf spring, designed for a truck (van) vehicles of a gross weight ofapp. 3,5 tons, makes the subject of considerations. This structural design is characterized by a clearance between the main and the auxiliary springs. The main objective of this work is to define the double spring strain during intense vehicle braking. A spatial FE shell double spring model has been proposed and it has been used for effort and deformation research on its selected elements, at combined load (vertical, horizontal forces and braking moment). Numerical tests have been performed within the quasistatic operation loads. The numerical analysis using those loads allows evaluating the braking force impact on the double spring operation and cooperation of the main and auxiliary spring leaves. Modelling and analysis issue, including contact issue, have been sohed by means of the software package for engineering computation by MSC. Software. Results obtained from simulations allow evaluating the deformation of individual leaves of the double spring, stress concentration areas and preliminary identification of the suspension (drive axle) kinematics, particularly to define axis trajectory of the wheel. Selected numerical test results have been compared to the experimental test results.

Opis:
This paper considers the braking process of a mine diesel locomotive with hydrostatic mechanical transmission (HSMT) operating according to the “input differential” scheme. Braking process modeling involves four implementation methods. Identification and systematization of basic regularities in the distribution of power flows within a closed transmission contour in the process of braking have been performed with the help of software support developed by means of MatLab/Simulink. The simulation results of braking due to the hydrostatic transmission and the braking system during the movement of a diesel locomotive in the transport and traction ranges are presented in the form of graphical correlations. The process of theoretical studies of the braking process of a diesel locomotive with HSMT operating according to the “input differential” scheme has helped determine that, in terms of deceleration at the expense of a hydrostatic drive (HSD) and braking system while preserving kinematic engine-wheels connection, it is not permitted to implement this method of braking process as it is followed by excess of the allowable value of working pressure differential within HSD up to 2.8 times.

Opis:
As a result of theoretical and experimental efforts, innovative scientifically grounded conceptual approach to select hydrostatic and mechanical transmissions (HMT) for wheel tractors designed for agricultural operations has been proposed. The approach is characterized by focusing on kinematic parameters, power parameters, and energy parameters of the transmission while performing technological operation “plowing”; it also takes into consideration braking features of a tractor in the context of various braking types. Application of the approach offers an opportunity to improve technical level of transmissions while updating current wheel tractors and designing new ones; moreover, that will better controllability as well as braking efficiency. The conceptual approach developed on the basis of proposed techniques and applied mathematical models makes possible to determine rational structure and basic design parameters of two-flow HMTs while designing; it also helps formulate recommendations concerning a technique for service braking and emergency braking under specific operational conditions.
