Abstract

The invention relates to a swing pin chain which bears large torque and impact load, a continuously variable speed change device equipped with the swing pin chain, and a power machine equipped with the continuously variable speed change device. Through the specific setting of the mutual proportional relationship and shape of the chain links, chain plates, swing pins and other components of the swing pin chain, and at the same time through the specific setting of the matching parts of the swing pin chain and the continuously variable transmission device, the continuously variable transmission is improved. The variable speed performance increases the load capacity of the continuously variable transmission, making it more suitable for high-horsepower machinery, and achieves technical effects such as impact resistance and fatigue life improvement.

Description

technical field [0001] The invention belongs to the field of gearboxes, and in particular relates to a continuously variable transmission device capable of bearing large torque and impact loads. Background technique [0002] The CVT transmission device applied to mobile machinery is that the chain or steel belt is wound between the moving and fixed cones. By changing the distance between the two cones, the working radius at the contact point between the chain or steel belt and the cone is adjusted to achieve speed change. This kind of gearbox has a stable transmission ratio, simple design and manufacture, and a wide range of speed changes. It has been reported that it is mostly used in the automotive field, and the input torque is below 400N.m. Non-road mobile machinery, such as agricultural machinery, construction machinery, etc., has a strong demand for continuously variable transmission due to the wide working range, but most of them have a large load, usually much greate...
