specific Embodiment approach

[0009] Such as figure 1 As shown, a pure electric vehicle through-axle second-speed planetary gearbox internal pressure seal ring includes a seal ring body 1, the seal ring body 1 is made of hydrogenated nitrile rubber, and the seal ring body 1 is circular , there is an air chamber 2 on it, and a fixing groove 3 is arranged on the sealing ring body 1; Both sides of slot 3.

[0010] The present invention is made of hydrogenated nitrile rubber material rubber, which can be used at a maximum temperature of 150 degrees Celsius and a minimum temperature of -10 degrees Celsius, and is resistant to gear lubricating oil. The surface of the sealing ring should be smooth, free of pores, pits, and cracks, and there are no dust particles in the sealing ring. , air bubbles, inclusions, small rigidity, soft material, and tear strength shall be checked and accepted according to the country's material rubber parts of this brand.

[0011] When in use, connect the steel plate 5 to the air cav...

Abstract

The invention discloses an internal compression seal ring of a two-gear planet gearbox of a pure electric vehicle through axle. The internal compression seal ring comprises a seal ring body, the seal ring body is made of hydrogenated nitrile rubber buna and in a round shape, an air cavity is formed in the seal ring body, and a fixed groove is formed in the seal ring body and communicated with the air cavity. A set of annular seal ribs are arranged on the seal ring body and are located on the two sides of the fixed groove respectively. The internal compression seal ring is simple in structure, the highest temperature for using the hydrogenated nitrile rubber buna is 150 DEG C, the lowest temperature for using the hydrogenated nitrile rubber buna is minus 10 DEG C, and the internal compression seal ring is resistant to gear lubricant, not prone to being damaged and long in service life.

Description

technical field [0001] The invention relates to the field of sealing rings, in particular to an internal pressure sealing ring of a second-speed planetary gearbox through the axle of a pure electric vehicle. Background technique [0002] There are many types of existing sealing rings, but none of them can withstand high temperature or gear lubricating oil, are easily damaged, and have high rigidity, unreasonable structure and shape, and are easy to tear. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a simple and practical pure electric vehicle through-axle second-speed planetary gearbox internal pressure sealing ring. [0004] The present invention is achieved in the following manner: [0005] An internal pressure sealing ring of a second-speed planetary gearbox through the axle of a pure electric vehicle, including a sealing ring body 1, characterized in that: the sealin...
