The invention discloses a hydraulic transmission gearbox, which comprises a power shift gearbox and a reduction box. The power shift gearbox and the reduction box are connected through an elastic support component and connected in a transmission mode through a universal coupling. The hydraulic transmission gearbox adopts a technical proposal that the power shift gearbox connected with an engine and the reduction box connected with a driving axle of a vehicle body achieve box connection through the elastic support component and achieve power transfer connection through the universal coupling, so that a power device of engineering machinery can be constructed relatively to a full floating type power arrangement of the vehicle body by adopting the engine and the power shift gearbox, so as tomeet low-vibration requirement of vehicles, improve running stability and riding comfort of the engineering machinery, and prolong service life of transmission parts.
Description
technical field [0001] The invention belongs to the technical field of mechanical power transmission, and in particular relates to a hydraulic transmission gearbox applied to engineering machinery such as forklifts and tractors. Background technique [0002] The patent document whose publication number is CN200978935Y discloses a hydraulic transmission gearbox, including a differential, a shift gearbox and a hydraulic torque converter, wherein the differential, the shift gearbox and the hydraulic torque converter are three The casing of the machine is fixedly connected, so that the vibration of the engine is directly transmitted to the car body through the shift gearbox and differential. Strong vibration will not only affect the running stability and ride comfort of the construction machinery, but also increase the transmission The wear of the components in turn affects the service life. Contents of the invention [0003] In order to solve the above-mentioned technical pr...
