The utility model discloses an oil suction cover for transmission lubrication system, which is characterized in that it includes an oil suction cover assembly, including an oil suction cover shell; a guide oil pipe connected with the oil suction pipe of the transmission is arranged above the oil suction cover shell, and an opening end is also arranged below the oil suction cover, and the opening end is provided with a filter mesh fixed to the oil suction cover shell in the initial state. The oil absorption hood assembly is always below the lubricating oil surface. Compared with the prior art, the filter screen of the oil suction cover is located at a distance below the lubricating oil surface, so the filter screen can still be below the lubricating oil surface during the process of the transmission uphill or downhill, basically avoiding the possibility of inhaling air, so the lubricating effect is more reliable and the service life of the lubricated gear is indirectly improved. The utility model also discloses a gearbox, including an oil suction cover for the lubrication system of the gearbox, which has corresponding advantages.

一种变速箱及其润滑系统用吸油罩
本技术涉及变速箱维护
,尤其涉及一种变速箱及其润滑系统用吸油罩。
技术介绍
在重型卡车变速箱中,通常采用强制润滑的方法对箱体中的齿轮、轴承等进行润滑。强制润滑系统主要由润滑油泵、吸油管、吸油罩以及喷油管组成。吸油罩从箱体底部储油区通过润滑油泵抽取润滑油,经过吸油管、喷油管的油孔喷到各齿轮和轴承上,从而达到润滑的效果。现有市场上的吸油罩通常采用圆柱形网状结构。当卡车在长时间处于上坡或者下坡的时候,变速箱也会行成向前或者向后倾斜的状态。在这两种情况下,圆柱形吸油罩容易有一部分露在润滑油面以上,当润滑油泵工作时,就会吸入大量空气混合在润滑油当中,从而大大降低润滑油的润滑效果。另外,混有空气的润滑油在润滑齿轮时,也会形成较大的啮合噪音,降低齿轮的使用寿命。
技术实现思路
本技术的目的是提供一种变速箱润滑系统用吸油罩,在变速箱发生倾斜的过程中,不易吸入空气,润滑效果更加可靠。为实现上述目的,本技术提供了一种变速箱润滑系统用吸油罩,包括吸油罩总成,其包括吸油罩外壳;所述吸油罩外壳上方设置有与变速箱吸油管相连通的导向油管,其下方还设置有开口端,所述 ...
