Problems solved by technology

[0005] 1. The back pressure is not stable and cannot be adjusted, because the engine speed is not constant, but changes within a certain range, so its back pressure is not a definite value. As the engine speed increases, its back pressure also increases. Increasingly, exceeding the allowable pressure value of the engine will cause harm to the engine itself
Although the maximum back pressure value can be limited by increasing the pressure relief hole, it also cannot solve the problem of unstable back pressure value, and the increase of the pressure relief hole usually reduces the back pressure value (because the design of the pressure relief valve should be based on The maximum speed of the engine is designed, and the speed of the engi

Embodiment Construction

[0024] The specific implementation manner of the present invention will be introduced below with reference to FIG. 3 and FIG. 4 . Figure 3 shows that the exhaust gas channel is in a disconnected state, and Figure 4 shows that the exhaust gas channel is in an open state. All parts with the same function as before in Fig. 3 and Fig. 4 use the same number.

[0025] The valve body 01 is used to assemble the components that complete the braking function into an assembly, the support rod 03 and the support sleeve 14 are used to fix the disc 02 at the designated position of the valve body 01, and the direction of the arrow represents the flow direction of the exhaust gas. Control rod 05 is fixed on the bottom of support sleeve by spring 07, pressing plate 09 adjustment support 10 and cover 08. At this time, the cavity 21 and the cavity 22 are divided into two parts by the control rod 05 . Disc 02 is in position 11 when no braking is required. When braking is required, the support ...

Abstract

The invention relates to an exhaust brake with stable and adjustable operating pressure, stable brake and sensitive brake reaction, comprising a valve body, a disc, a supporting rod, a supporting sleeve, a control rod, a spring and an adjustable bolt without a pressure relief vent, wherein, the supporting rod and the supporting sleeve are used for fixing the disc, the control rod is used for controlling the on and off of an exhaust channel, the spring is used for adjusting the size of the operating back pressure of an assembly. The exhaust brake can release the excess pressure in time when the pressure surpasses the presetting value due to any unforeseen circumstances and guarantees the stable and reliable operating pressure; moreover, the exhaust brake with the decompressor has adjustable operating pressure, simple and convenient implementation and reliable performance.

Description

technical field [0001] The invention relates to an exhaust brake with stable and adjustable working pressure, stable braking and sensitive braking response. technical background [0002] The retarder is an auxiliary braking device for vehicles (especially heavy-duty trucks and large passenger cars). The use of auxiliary braking devices can enhance the braking performance of vehicles without using or using less main brakes (traditional friction brakes) The vehicle can be controlled within a certain safe speed range, the brake failure of the vehicle can be prevented, and the driving safety can be ensured, especially the safety when the heavy-duty vehicle goes down a long slope can be enhanced. At the same time, using the retarder can significantly reduce the frequency of use of the main service brake (friction brake), thereby reducing the wear of the main brake hub and friction plate, improving its service life, and at the same time prolonging the maintenance cycle of the main...
