Abstract

The invention discloses a hydraulic transmission device which comprises a front driving part, a transmission part and a back driving part. A transmission rod used for transmitting power is arranged in the transmission part, one end of the transmission rod is selectively connected with the front driving part, the other end of the transmission rod is connected with an end socket device, the end socket device is connected with the back driving part in a rotatable mode, the end socket device comprises sealing rubber and a sealing sheet connected with the sealing rubber, the sealing sheet comprises an upper sealing sheet body and a lower sealing sheet body, and an emergency oil way is formed between the upper sealing sheet body and the lower sealing sheet body. According to the hydraulic transmission device, the end socket device in the split design is adopted, under the condition that a transmission cavity is lacking of oil, stored reserved oil is automatically injected into and used for lubricating a whole end socket, and the dry pulling phenomenon is effectively prevented.

Description

[0001] technical field [0002] The invention relates to a mechanical transmission device, more precisely, a hydraulic transmission device. [0003] Background technique [0004] A hydraulic transmission device is a device that uses fluid pressure to transmit power. In this device, a positive displacement hydraulic pump and a hydraulic actuator (hydraulic cylinder or hydraulic motor) are used. The head device of the existing hydraulic transmission device is generally formed by integral processing technology, but the lack of lubricating oil in this integrally formed head device is very easy to cause the so-called "dry pull". This imagination is likely to cause damage to the entire head device. [0005] Chinese invention patent ZL201110071398.4 discloses a transmission system based on hydraulic or electric transmission of parallel shaft main transmission. It is composed of engine, main transmission device, hydraulic pump, hydraulic motor and half shaft, etc. The input shaft...
