Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] like figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 Embodiment 1 is shown, which includes a hydraulic supply system and a damping device. The hydraulic supply system includes an air reservoir 1 , a solenoid valve 2 , a gas-liquid conversion cylinder 3 and a synchronous liquid regulating valve 4 . The damping device comprises two closed fixed frame shells 13,14 that are clamped and fixed together, a camshaft 9 with a three-lobe cam 7 in the middle, and is located in the two fixed frame shells 13,14 and fixed on the bottom surfaces of the two fixed frame shells 13,14. Six hydraulic cylinders 5 on the inner wall. The two fixed frame housings 13, 14 are respectively fixed on the shafts at both ends of the camshaft 9 by the bearing 8 and the oil seal 11, and the fixed disk 26 of the camshaft 9, the transmission shaft 21 and t...

Abstract

The invention discloses a car braking device suitable for a mountain road, which is fixedly arranged at any one position, two positions or three positions between a car gearbox and a driving shaft, between the driving shaft and a hanging basket, and between the driving shaft and a differential device; the car braking device comprises a hydraulic or atmospheric feed system and a damping device; the damping device comprises two fixed mount housings which are fixed together to be sealed, a camshaft with a cam in the middle, and one or more air cylinders or hydraulic cylinders which are arranged in the two fixed mount housings and fixed on the inner walls of the two fixed mount housings; and when a piston rod is ejected, the top end of the piston rod is supported on the cam edge of the cam shaft. According to the car braking device, a small braking force is applied to the driving shaft, and accordingly, a large braking force is generated on wheels, so that the car braking device is labor-saving to brake; and when the car runs downhill, the car braking device can be simultaneously used with a car master braking device, so that the braking time and the braking frequency of the master braking device can be reduced, the temperature of the braking device and the master braking device can be reduced, the dysfunction of the braking can be avoided, and the happening of accidents caused by the dysfunction of the braking can be reduced.

Description

technical field [0001] The invention relates to a braking component used in automobiles, in particular to a vehicle braking device suitable for mountain roads. Background technique [0002] Automobile braking has become more and more advanced along with the development of the automobile industry. However, its braking end is generally installed on the automobile wheel hub, and the friction between the disc type and the drum type friction plate and the automobile wheel hub is used as the braking force. [0003] There are many cars in our country driving in high mountains and mountains all year round. The slope of the road is not only large but also very long. When the car goes downhill, it needs to start the brake device for a long time and high frequency. The friction between the friction plate and the car hub will generate heat and the braking time The longer the frequency, the higher the temperature between the friction plate and the hub of the car, which will eventually l...
