Abstract

The invention provides a transmission mechanism with a compact structure and a wide transmission ratio, including a planetary row and a fixed shaft gear assembly composed of a sun gear, a planetary carrier, a planetary gear and a ring gear; the sun gear is sleeved on the input shaft, and the ring gear Connected with the output shaft; the fixed shaft gear assembly includes a first spur gear sleeved on the input shaft, a second spur gear fixedly connected to the planet carrier, and a third spur gear sleeved on the transmission shaft and The fourth spur gear; the first spur gear meshes with the third spur gear; the second spur gear meshes with the fourth spur gear; a dial sleeved on the input shaft is provided between the first spur gear and the sun gear The fork; the shift fork includes a movable part and fixed parts respectively arranged on both sides of the movable part; the two fixed parts are respectively fixedly connected with the first spur gear and the second spur gear. The transmission mechanism can realize a wide range of transmission ratios, realize high-speed driving and low-speed operation at the same time, and has ingenious design, compact components, small volume and convenient installation.

Description

technical field [0001] The invention relates to a transmission mechanism, in particular to a transmission mechanism with a compact structure and a wide transmission ratio. Background technique [0002] The mobility and load-bearing capacity of modern vehicles are constantly improving, and the transmission plays a vital role in the vehicle's mobility and load-bearing capacity. In order to meet the high mobility and high load requirements of the vehicle, the transmission device must have a wide range of transmission ratios: small transmission ratios can meet the needs of high output speed and high-speed travel; large transmission ratios can achieve low output speeds and large output torque functions, suitable for climbing Working conditions such as load. [0003] Taking engineering equipment as an example, it is necessary to have both high-speed driving capability and ultra-low-speed engineering operation (dozing, mine clearance, excavation, etc.) capabilities. The transmiss...
