Embodiment Construction

[0028] Such as figure 1 and 2 As shown, the push rod 8 at the output end of the cylinder 2 is connected to the connecting fork 3, one end of the articulated rocker arm 4 of the connecting fork 3 is rotatable, the other end of the rocker arm 4 is fixedly connected to the rotating shaft 5, and the rotating shaft 5 runs through the valve body 6 and the valve plate 7. The valve plate 7 can rotate around the rotating shaft 5 in the valve body 6. The rotating shaft 5 is offset by a certain distance relative to the center line of the valve plate 7. The bracket plate 1 and the valve body 6 have an integral structure, or the bracket plate 1 is fixed on the valve body. On the body 6, the cylinder 2 is fixed on the support plate 1, and the rotating shaft 5 deviates from the extension line of the output end push rod 8 of the cylinder 2.

[0029] The end of the cylinder 2 away from the push rod 8 has an air inlet 16. The cylinder 2 is composed of a plunger cylinder and a single-acting cyl...

Abstract

A car engine exhaust braking valve, including valve body, air cylinders which are constituted with plunger cylinder and one-way cylinder, the plunger cylinder transmits the push force to the one-way cylinder, whose pushing bar extends outside of shell of the cylinders and twists with the rocker arm; the exhaust braking valve is small in geometric shape, easy installation, and low maintenance costs.

Description

technical field [0001] The invention relates to a vehicle auxiliary brake device, in particular to a novel exhaust brake valve used for an automobile engine. Background technique [0002] Automobile engine braking system is one of the important devices for safe driving of automobiles. When the vehicle needs to decelerate, especially in mountainous areas or when urban buses need to brake frequently, if the service brake is used frequently, the wheel brake will overheat and the braking function will decline. If emergency measures (stop cooling) are not taken in time, even This can result in complete failure of the brakes and a dangerous vehicle situation. Therefore, it is very necessary to adopt non-fading auxiliary braking system for this situation. The use of auxiliary braking devices can enhance the braking performance of the vehicle, and the vehicle can be controlled within a certain safe speed range without using or using less brakes (traditional friction brakes), preve...
