Abstract:

The paper describes a new system of mechanical spherical conical friction drive. In the present a row of simple friction, belt, chain, wave and differential variable speed drives is published. For the required range of speed variation they are altogether unfit. The currently used power transmissions are of low efficiency (60&ndash;70%). Therefore the better power transmission efficiency is required. The possibility of multicontact power transmission appears as the most suitable principle of the power transmission. Using the designed function model, which was made according to the small tra

Magnetic transmissions have certain structural advantages compared to mechanical transmissions, namely: high reliability, efficiency, lower losses, non-contact transmission of mechanical power, no maintenance costs, and simplicity of construction. The use of magnetic transmissions for systems of conversion of low-potential mechanical energy into electrical energy is especially relevant: wind energy, water energy, energy of mechanical vibrations, etc. The us

The aim of this work is to design a power split transmission for an urban street sweeper in order to reduce fuel consumption.

This paper employs hybrid modelling techniques in the investigation of the dynamic performance of ‘long’ driveshafts, which include a clutch and load, for power transmission purposes. The power transmission system considered is suitable for a wide variety of applications in which the load is coupled directly to the clutch and hence to the ‘long’ driveshaft. Owing to the length of the shaft and relatively pointwise location of the clutch and load, a distributed—lumped (D—L) description of the arrangement is investigated. This enables the behaviour of the dispersed driveline shaft to be ‘adequat

A lot of publications are devoted to the study of gear transmission, which cover all the features of their design, operation and repair. An in-depth analysis of factors that were not taken into account a decade ago was carried out. The efficiency of the drive, taking into account air resistance, and the stress-strain state of the tooth, taking into account centrifugal deformations, were determined. Thus, there are constant complication of the tasks that researchers set themselves. At the same time, recent achievements in the natural sciences have led to a narrowing of the field of use of gears

The hydro-mechanical transmission system (HMTS) operates either in power split transmission mode (PSTM) or power reflux transmission mode (PRTM). Although PRTM is often ignored as a transition mode, this study reveals that the HMTS operating in the PRTM can accumulate the power input from the power source in the form of reflux power (in some references, scholars also refer to the reflux power as circulating power), thereby enabling the HMTS to exhibit a similar transmission performance as hydrodynamic transmission systems. Accordingly, this study applies the PRTM to the starting of constructio

Abstract:

The Hydro-mechanical variable transmission (HMT) is an infinitely variable and high efficient multi-power flow transmission, whose stepless speed ratio changing process includes speed ratio changing in range and power shift. In this paper, a HMT control strategy is proposed that includes four components: speed control strategy in range, power shift condition, power shift logics and power shift control strategies. The simulation results of the two-range HMT demonstrate that the proposed control strategy can stabilize the engine speed to the target operating area near the optimal speed and can s

Abstract:

This article shall explore the characteristics of hydro-mechanical transmission in power shift. Based on the double brakes overlapping, the adjustment of the displacement ratio of variable-displacement hydraulic component is considered, and then a new full power shift method is proposed. Models respectively for speed, torque, and power in the power shift process are built. The ideal power shift timing is deduced, with the ratio between speed of fixed-displacement hydraulic component and input speed being the criterion. By combining theoretical analysis and experimental studies, it shows that i

Abstract:

In this work, a power-split continuously variable transmission (CVT) used in high-power tractors is considered. Power-split CVTs are characterized by the combination of a traditional discontinuous mechanical transmission and a continuously variable transmission. This provides, at the same time, smooth variations of the transmission ratio and high efficiency of the overall transmission system. The CVT considered in this paper is a hydrostatic power-split unit conceived for top-power agricultural tractors. The goal of this paper is to present a case study on the design and tuning of the control

Abstract:

The power transmission system is a critical component of any machine. Accordingly, the detailed analysis of this system is essential for both design purposes and the detailed assessment of machine performance. Due to the large number of possible power transmission system components and the nature of these systems, general power transmission system analysis methods have been difficult to develop. However, such analysis methods could meet a wide variety of needs for system design. This paper discusses the general power transmission system analysis approach developed by the authors over the last
