Embodiment Construction

[0019] The invention will be described in more detail hereinafter with reference to the accompanying drawings showing embodiments of the invention. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In these drawings, the size and relative sizes of layers and regions may be exaggerated for clarity.

[0020] The present invention is a hydraulic speed reducer that can provide sufficient rotational torque through the accumulation of relatively small power of the engine. This device is mainly used when the motor vehicle climbs a steep slope or travels on a muddy road. When the mechanical gearbox is not enough to provide traction, By starting the device, after slightly delaying the pressurization process, within the range of...

Abstract

The invention discloses a large-torque hydraulic reduction gearbox which comprises an oil return tank, multistage hydraulic pumps and a hydraulic motor. Oil paths of the oil return tank, the multistage hydraulic pumps and the hydraulic motor are sequentially connected to form a loop for circulation of hydraulic oil; a vehicle engine drives the multistage hydraulic pumps through a transmission shaft, and the hydraulic motor drives wheels through a drive shaft; the vehicle engine inputs mechanical energy to the transmission shaft which drives the hydraulic oil to conduct multistage step-type pressurization through the multistage hydraulic pumps, the pressurized hydraulic oil is input to the hydraulic motor, the hydraulic motor converts high pressure energy of the hydraulic oil into mechanical energy and conveys the mechanical energy to the wheels through the drive shaft, and the drive shaft drives the wheels to rotate. By means of the large-torque hydraulic reduction gearbox, the problem that when a load-carrying motor vehicle climbs an abrupt slope or runs on a muddy road, the motor vehicle cannot move forwards due to the fact that the engine power is insufficient is solved; the engine drives the hydraulic pumps to conduct multistage pressurization on the hydraulic oil, the intensity of pressure of the hydraulic oil is continuously increased, and the purpose of driving the hydraulic motor to provide large enough traction force to the wheels is finally achieved.

Description

technical field [0001] The invention relates to the technical field of reduction gear design, in particular to a high-torque hydraulic reduction box. Background technique [0002] In the overall design and manufacture of motor vehicles, in order to pursue its good economic performance and sports performance, there will not be too much overload margin in the power selection of the engine, and the mechanical gearbox also has a maximum reduction ratio Therefore, the maximum traction force of a motor vehicle is also basically limited within a certain range. When a motor vehicle encounters a steep slope or a muddy road under a load situation, it often encounters a situation that cannot move forward due to insufficient traction force. Therefore, it is necessary to study a device that can finally achieve the traction required for climbing steep slopes or muddy roads by accumulating the output energy of the engine under the condition of constant engine power. [0003] At present, t...
