Problems solved by technology

In the current CVT continuously variable transmission mechanism, the transmission belt is the most important torque receiving part. Now belts or steel belts are commonly used as transmission belts, but whether it is a belt or a steel belt, the torque it can withstand and transmit is limited. It hinders the improvement of the automobile torque, hinders the development of the automobile industry, and the transmission belt is prone to breakage when used for a long time, leading to safety accidents

Abstract

The invention relates to a shunting type (Continuously Variable Transmission) mechanism and a torque transferring method thereof. The shunting type mechanism comprises a box body (1), an input belt pulley mechanism (2), an output belt pulley mechanism (3) and a torque output mechanism (8), wherein the input belt pulley mechanism (2) and the output belt pulley mechanism (3) are connected with the box body (1) and a transmission belt (15) is connected between the input belt pulley mechanism (2) and the output belt pulley mechanism (3), a first gear (4) is connected with a transition gear mechanism (5) connected with a shell gear (68), a first differential mechanism (6) is arranged on the box body (1), two sides of the first differential mechanism (6) are respectively provided with a second gear (10) and a third gear (9), a second differential mechanism (7) is fixedly arranged on the box body (1), two sides of the second differential mechanism (7) are provided with a fourth gear (12) and a fifth gear (11), and the second differential mechanism (7) is connected with the torque output mechanism (8). According to the shunting type mechanism disclosed by the invention, an input torque is divided into two parts so that the load of the transmission belt is lightened and the upper limit of a transferring torque is largely increased.

Description

technical field [0001] The invention relates to the field of mechanical transmission mechanisms, in particular to a split-flow CVT continuously variable transmission mechanism and a torque transmission method thereof. Background technique [0002] The CVT continuously variable transmission is usually a kind of automobile transmission mechanism, which has a history of more than one hundred years. The difference with the stepped transmission is that its transmission ratio is not a discontinuous point, but a series of continuous values, so as to achieve a good The economy, power and driving comfort, and reduce emissions and costs, so it is widely used. In the current CVT continuously variable transmission mechanism, the transmission belt is the most important torque receiving part. Now belts or steel belts are commonly used as transmission belts, but whether it is a belt or a steel belt, the torque it can withstand and transmit is limited. It hinders the improvement of automob...
