Embodiment 1

[0020] Such as Figure 1-3 As shown, the present invention discloses an exhaust muffler structure for a parallel hydraulic retarder, including a retarder oil chamber cover and a silencer assembly, and the retarder oil chamber cover is separately provided with an oil collection chamber 1, a working Cavity 2, pressure stabilizing chamber 3, oil inlet passage 4 and oil outlet passage 5. The pressure stabilizing chamber 3 is arranged at one end of the retarder oil chamber cover. The assembly is installed in the air outlet 7.

[0021] The shape of the retarder oil chamber cover adopts a rectangular design. The oil collection chamber 1 is set on the lower half of the retarder oil chamber cover, and the working chamber 2 is set on the surface of the retarder oil chamber cover. It adopts a hemispherical design. Staggered ribs 6, the oil inlet passage 4 is arranged on the side of the working chamber 2 and runs through the retarder oil chamber cover, and the oil outlet passage 5 is arr...

Abstract

The invention relates to the field of machine design and discloses an exhausting and silencing structure for a parallel connection hydrodynamic retarder. The exhausting and silencing structure comprises a retarder oil chamber cover and a silencing assembly. Through structural optimal design, an O-shaped seal ring, a silencer piece and a fixed stop ring form the silencing assembly in a compound mode. Rigid deformation of the silencer piece is reduced through flexible deformation of the O-shaped seal ring. Tight combination of the silencing assembly and the oil chamber cover is achieved through the fixed stop ring. The silencing assembly is designed reasonably, a porous filter element is coated with a stainless steel sintering filter screen, thus emitted gas forms irregular turbulence in the silencing assembly so as to be reduced, and when the silencing assembly loses efficacy, the silencing effect can be recovered only by replacing the porous filter element.

Description

technical field [0001] The invention relates to the field of mechanical design, in particular to an exhaust muffler structure for a parallel hydraulic retarder. Background technique [0002] Hydraulic retarder is also called hydraulic deceleration device. Cars use exhaust brake when going down a long slope. Although they can receive a good braking effect, for heavy vehicles with a larger tonnage, the exhaust brake effect is limited. Therefore, hydraulic deceleration retarders are installed on heavy vehicles equipped with hydromechanical transmission. [0003] The hydraulic retarder adopts the principle of hydraulic power. It includes a working chamber, an oil storage chamber and a cooler. A pair of stator impellers and rotor impellers are sealed in the working chamber. The rotor impeller is linked with the vehicle power shaft. There are vanes on the top, and the working chamber is connected with the oil storage chamber. When braking is required, the control device sends a ...
