裝載機(jī)廣泛應(yīng)用于松散貨物和成堆貨物的裝載、提升和運(yùn)輸,它具有很好的力量與機(jī)動(dòng)性能的結(jié)合,有很大的經(jīng)濟(jì)性和實(shí)用性。
Loaders widely used in loose piles of goods and cargo loading, lifting and transport, it has a good combination of strength and mobility, there is great economic and practical.
靜壓傳動(dòng)相對(duì)于動(dòng)壓傳動(dòng)而言,一方面是它的結(jié)構(gòu)形式可以實(shí)現(xiàn)綜合傳動(dòng)方案,并且允許在現(xiàn)代化輪胎式裝載機(jī)中傾斜于或橫向于行駛方向安裝。在閉環(huán)回路中,可使轉(zhuǎn)矩以兩個(gè)方向傳遞。另一方面它具有很大的控制范圍,在附加的換檔變速器中可以實(shí)現(xiàn)無級(jí)或只有少量的幾級(jí)換檔。
Hydrostatic transmission with respect to the dynamic pressure transmission is concerned, on the one hand is its structure can achieve a comprehensive drive program, and allows the modern tilt wheel loaders or transverse to the direction of travel on the installation. In closed loop, can transmit torque in both directions. On the other hand it has a large control range, the shift in the transmission of the additional stage can be achieved without or only small amounts of a few levels shifts.
因此,在剎車過程中,能夠產(chǎn)生一個(gè)作用于驅(qū)動(dòng)機(jī)械的“支撐”,從而可以減少剎車功率和剎車磨損,這些將帶來輪胎式裝載機(jī)營(yíng)運(yùn)費(fèi)用的降低。在剎車的同時(shí)操作工作液壓,可使回流的能量附加傳給另一個(gè)液壓泵和執(zhí)行元件。靜壓傳動(dòng)決定性的優(yōu)點(diǎn)是:它具有各種各樣的開環(huán)控制和閉環(huán)控制,并且在任何轉(zhuǎn)速下都能接納可支配發(fā)動(dòng)機(jī)功率。因此,在當(dāng)前和未來的研究發(fā)展中,對(duì)輪胎式裝載機(jī)傳動(dòng)裝置進(jìn)行優(yōu)化設(shè)計(jì)已成為一種必然趨勢(shì)。
Thus, during braking, to generate a driving mechanism acting on the "support", thereby reducing the power brake and brake wear, which will bring lower the operating cost of the wheel loader. In the simultaneous operation of the brake hydraulic work, make another pass additional energy backflow hydraulic pump and actuators. Hydrostatic transmission decisive advantages: it has a variety of open-loop control and closed-loop control, and can be accepted at any speed disposable engine power. Therefore, in the current and future research and development, the right wheel loaders
transmission to optimize the design has become an inevitable trend.
在應(yīng)用靜壓傳動(dòng)時(shí),由于它可以自由分配轉(zhuǎn)速變換和轉(zhuǎn)矩變換,理論上它可以覆蓋整個(gè)發(fā)動(dòng)機(jī)的特性曲線族。并且與各式開環(huán)和閉環(huán)控制相結(jié)合,還可以實(shí)現(xiàn)噪音和能量消耗的優(yōu)化。這樣,只要將驅(qū)動(dòng)馬達(dá)轉(zhuǎn)速調(diào)控在一個(gè)最佳工作點(diǎn)上,司機(jī)只通過油門踏板的位置,就可以對(duì)加速、牽引力或速度提出工作所需要求。 除了性能上的優(yōu)勢(shì)以外,現(xiàn)代化的、與專門的驅(qū)動(dòng)功率相協(xié)調(diào)的液壓靜壓傳動(dòng)方案相對(duì)液力變矩器傳動(dòng)方案在價(jià)格上也是極具競(jìng)爭(zhēng)力的。
In the application of hydrostatic transmission, because it can be freely assigned speed and torque conversion transformation, theoretically it can cover the entire family of characteristic curves of the engine. And with a variety of open-loop and closed-loop control of a combination, may also be implemented to optimize the noise and energy consumption. Thus, as long as the regulation of the drive motor at a speed of the optimum operating point, the position of the accelerator pedal by the driver only, it is possible to accelerate the traction force or speed on its work necessary requirements. In addition to performance advantages, modern, with a special driver coordinated hydrostatic power transmission scheme relative torque converter transmission scheme in the price is also very competitive.
