Abstract

The invention discloses a walking transmission device of an operation vehicle and a control method of the walking transmission device. The walking transmission device comprises an input shaft, a mechanical transmission assembly, a hydraulic transmission assembly, a convergence assembly, a walking power output shaft and an operation power output shaft. The input shaft is connected with the mechanical transmission assembly and the hydraulic transmission assembly which are connected in parallel, power of the mechanical transmission assembly and power of the hydraulic transmission assembly converge through the convergence assembly and then are transmitted to the walking power output shaft after, and the operation power output shaft is connected with the mechanical transmission assembly. The device has the beneficial effects that two gears are adopted for hydraulic transmission, and the requirements of various precise operations and a wide speed regulation range are met; the hydraulic transmission high gear can be synchronously shifted with mechanical hydraulic transmission gears, and the function of connecting the plurality of mechanical hydraulic transmission gears to achieve gear shifting without power interruption is achieved; and the plurality of gears of the mechanical transmission mechanism are combined with double characteristic parameters of the convergence mechanism, so that the speed regulation range and the freedom degree of the whole transmission device are expanded.

Description

technical field [0001] The invention relates to a traveling transmission device and a control method thereof, and in particular provides a traveling transmission device and a control method of an operating vehicle that realize precise and free speed regulation. Background technique [0002] The mechanical-hydraulic compound transmission generally adopts hydraulic transmission to realize the starting working condition, the mechanical-hydraulic transmission meets the operating conditions, and the mechanical transmission completes the transition working condition, and adapts to the operating requirements of various working conditions within the entire speed regulation range. Common mechanical-hydraulic compound transmissions have relatively few gears in each mode, making it difficult to achieve precise and free speed regulation. Contents of the invention [0003] Purpose of the invention: Aiming at the deficiencies in the prior art, the present invention provides a traveling ...
