Abstract
The utility model discloses a hydraulic transmission gear which comprises a front drive part, a transmission part and a rear drive part. A transmission rod used for driving motive power is arranged inside the transmission part, one end of the transmission rod is optionally connected with the front drive part, and the other end of the transmission rod is connected with an end socket device which is rotatablely connected with the rear drive part. The end socket device comprises sealing rubber and a sealing piece connected with the sealing rubber. The sealing piece comprises an upper sealing piece and a lower sealing piece, and an emergency oil circuit is formed between the upper sealing piece and the lower sealing piece. Due to the fact that the hydraulic transmission gear uses the end socket device which is designed in a split mode, on the condition that a transmission cavity is lack of oil, the hydraulic transmission gear can automatically pour stored spare oil into an end socket and lubricate the whole end socket, and a phenomenon of 'pulling without oil' is effectively prevented from happening.
Description
Technical field
The utility model relates to a kind of mechanical transmission, or rather, is a kind of hydraulic transmission.
Background technique
Hydraulic transmission is a kind of device that utilizes the pressure energy transferring power of fluid, uses volume-type hydraulic pump and hydraulic actuator (oil hydraulic cylinder or oil hydraulic motor) in this device.The end-sealing device of existing hydraulic transmission generally adopts integral processing to form, but under the lubricated oil condition of the shortage of this integrated end-sealing device, as easy as rolling off a logly causes so-called " dried drawing ".This imagination easily causes whole end-sealing device to be damaged.
Chinese utility model patent ZL201110071398.4 discloses a kind of transmission system of the parallel-axis type main transmission based on hydraulic pressure or electric transmission.Formed by motor, main transmission, oil hydraulic pump, oil hydraulic motor and semiaxis etc., main transmission input shaft and output shaft axis parallel layout, the oil hydraulic motor that is connected with the main transmission input shaft is connected with the input shaft coaxial inner conductor.Power transmission process is: power is passed to the main transmission input shaft by oil hydraulic motor, through the small gear on the input shaft and gearwheel engagement, again from connecting the output shaft output of gearwheel.The input shaft of the utility model parallel-axis type main transmission is parallel with output shaft, and oil hydraulic motor and the input shaft coaxial with input shaft are integrally formed gasifying device, can realize around 0 ° of output shaft--and 180 ° space mounting is arranged.Two oil hydraulic motors and main transmission input shaft, or a plurality of oil hydraulic motor and a plurality of main transmission input shaft consist of single input, single output, and the version of the diversified main transmissions such as many inputs, single output can transmit larger power.This hydraulic transmission also is to adopt integrated end-sealing device, and fatigue damage easily occurs.
Chinese utility model patent ZL200810099148.X discloses a kind of construction plant, and this construction plant comprises: transmission device; At least one fluid pressure drive device; And oil hydraulic circuit, be used to fluid pressure drive device that hydraulic fluid is provided; Wherein, at least one lubricating pipe from the oil hydraulic circuit bifurcated out, can be transmission device by described lubricating pipe provides hydraulic fluid as oiling agent.Of the present utility model being characterised in that: provide measuring apparatus at lubricating pipe, according to the operating conditions of transmission device, use described measuring apparatus can change the delivery volume of oiling agent.Equally, this fluid pressure drive device has adopted similar global design, easily causes the appearance of " dried drawing " phenomenon.
The model utility content
The utility model mainly is to solve the existing technical problem of prior art, thereby a kind of hydraulic transmission that can effectively prevent end-sealing device " dried drawing " of split design is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of hydraulic transmission, comprise front wheel driving section, transmission unit and rear driving section, be provided with a drive link for transfer motion power in the described transmission unit, one end of described drive link selectively is connected with described front wheel driving section, its another end is connected with an end-sealing device, described end-sealing device is connected rotationally with described rear driving section, described end-sealing device comprises caulking gum and the diaphragm seal that is connected with described caulking gum, described diaphragm seal comprises diaphragm seal and lower sealing piece, has consisted of an emergent oil circuit between described upper diaphragm seal and the lower sealing piece.
As the utility model preferred embodiment, be provided with an emergent oil groove between described upper diaphragm seal and the lower sealing piece, described upper diaphragm seal and lower sealing piece are symmetrical arranged the both sides of described emergent oil groove.
As the utility model preferred embodiment, described upper diaphragm seal and lower sealing piece are that teflon is made.
As the utility model preferred embodiment, described upper diaphragm seal is connected with described caulking gum by screw assembly with lower sealing piece.
Because hydraulic transmission of the present utility model utilizes the end-sealing device of split design, so that in the situation that drive cavity at oil starvation, can inject the oil for subsequent use that stores and lubricated whole end socket automatically, effectively prevent the appearance of " dried drawing " phenomenon.
