The dynamic traction force in Figure 1 indicates that the vehicle can generate forward motion. Further, based on the differential equation of the vehicle’s motion, the displacement, velocity, and acceleration of the vehicle when it is trapped can be obtained, as shown in Figure 2. From the displacement curve...
For vehicles equipped with ordinary bevel gear differentials, when one side of the driving wheel slips due to reduced friction coefficient, the vehicle is prone to insufficient power and cannot move forward. To address this issue, non circular gear differentials can sense wheel slip and achieve rapid disengagement without...
The average moving speed va of the vehicle is used to reflect the anti slip and disengagement ability of the non circular gear differential, and the maximum acceleration am of the vehicle is used to reflect the comfort of the passengers during the disengagement process. By changing the input...
According to the formula, the torque allocated to the two drive wheels can be calculated, as shown in Figure 1, where T1 represents the torque of the differential to the left slipping drive wheel and T2 represents the torque of the differential to the right non slipping drive wheel....
The basic configuration of a non circular gear differential is shown in the figure, which consists of non circular gears 1 and 2, small cylindrical spur gears (planetary gears) 3, planetary gear shaft 4, and planetary carrier (differential housing) 5. Among them, non circular gears 1 and 2 are...
(1) A variable transmission ratio differential composed of non circular gears is proposed. Due to the point meshing transmission between non circular gears and ordinary cylindrical gears, this differential has outstanding advantages over non conical gear differentials in terms of good interchangeability and strong axial fault tolerance. (2) The...
Taking a certain rear wheel drive vehicle as a simulation example, the main parameters of the vehicle and its corresponding non circular gear differential are shown in the Table. When a general circular gear differential slips on one side of the wheel（ μ The locking coefficient of 1=0.1 is...
The prototype of a second-order non circular gear differential is shown in Figure 1, mainly composed of non circular gears 1 ‘and 2’, small cylindrical spur gears 3 ‘and 5’, planetary shaft 4 ‘, connecting arms 6’ and 9 ‘, right housing 7’, and left housing 8 ‘. The...
Among numerous limited slip differentials, variable transmission ratio differentials have outstanding advantages such as the simplest structure, convenient maintenance, low wear, and long service life. They have great application value in off-road vehicles, but there are defects such as manufacturing difficulties and weak anti slip ability. To this end,...
The non circular gear differential consists of a new type of spatial variable transmission ratio gear, as shown in the figure, which is a second-order non circular gear that can mesh with a standard involute gear for transmission. In general, a small cylindrical spur gear is the driving wheel,...
