Problems solved by technology
[0003] Since the oil in the hydraulic steering system of agricultural machinery, construction machinery and other equipment will continue to become dirty during normal operation, the dust outside will enter the fuel tank along with the breathing device and the fuel filler, especially the metal shavings from the oil pump and metal pipe fittings will enter the fuel tank. If it is light, it will cause damage to the parts, and if it is serious, it will cause the steering system to fail and cause an accident. The hydraulic steering oil tank used in the existing steering device cannot solve the problem of metal shavings and dust entering the steering hydraulic system.

The invention discloses a filter-unit-bearing hydraulic steering oil tank which is provided with a filter unit, wherein the filter unit comprises a filter screen supporting seat (5), an oil cup (9), a spring (11), a filter screen (12) and a filter screen rubber pad (13); an oil outlet (6) on a lower shell (4) is provided with the filter screen supporting seat (5); the filter screen supporting seat (5) is provided with the filter screen (12) through the filter screen rubber pad (13); the oil cup (9) is installed in the lower shell (4) outside the filter screen (12); one end of the spring (11) is sheathed on the inner cylinder of the oil cup (9); and the other end of the spring (11) is sheathed in a pit of the filter screen (12). The filter-unit-bearing hydraulic steering oil tank enables the engine oil in the steering system to be clean without harmful particles, ensures the normal operation and flexible steering of equipment, relieves the operational fatigue strength of the driver, and reduces the vibratory response of the pavement to the steering system.
Description
technical field [0001] The invention relates to a hydraulic steering oil tank mainly used in agricultural machinery, engineering machinery and other equipment, in particular to a hydraulic steering oil tank with a filtering device. technical background [0002] A hydraulic steering device is needed in all mechanical equipment in our country, and the oil storage tank, an important part of the steering device, not only provides the hydraulic oil required for steering, but also ensures the cleanliness of the required oil, reducing the amount of metal in the oil. Protect hydraulic oil pump, steering gear and other accessories. At present, the country is speeding up the process of agricultural modernization, various policies to benefit farmers, and agricultural machinery subsidies are increasing. The demand for agricultural machinery will increase, and the demand for hydraulic steering devices and hydraulic steering oil tanks in steering devices will also increase. With the rapid...
