detailed description

Example 1

Referring to FIG. 1 to FIG. 5, the embodiment includes a casing 1, a brake structure 2 located in the casing, and a main shaft flange 3. . The outer casing 1 is composed of a toroidal casing 11, a front cover 12 and a rear cover 13, and the main shaft flange 3 is located in the middle of the casing 11 and is connected to the automobile transmission shaft. The main shaft flange 3 is rotatable relative to the outer casing 1. The main shaft flange 3 is sealed with the housing 11, the front cover 12 and the rear cover 13 by a rotatable oil seal 4 to form a sealed annular cavity 5. The brake structure 2 consists of a rotor 21 located in the annular cavity 5 and mounted on the main shaft flange 3 via a bearing 6. The outer wall of the rotor 21 is provided with a plurality of blade holders 22, and the blade holder 22 is provided with a blade 23 slidable relative thereto. The rotor 21 is coupled to the main shaft flange 3 via a clutch assembly 7, which controls the separation and closure of the rotor 21 from the main shaft flange 3.

The oil inlet hole 15 and the oil outlet hole 16 pass through the end face of the housing connected to the front cover and pass through the front cover. Two curved concave surfaces 14 are evenly distributed in the circular surface of the inner cavity of the casing 1. An inlet 15-1 communicating with the external pipeline is provided near the oil inlet hole 15, and an outer pipe is provided near the oil outlet hole 16. The road is connected to the exit 16-1. Using a pressure regulating valve, an oil inlet hole 15 in one curved concave surface 14 and an oil outlet hole 16 in the other curved concave surface 14 are connected by a pressure regulating valve. Similarly, the other oil inlet holes 15 and the oil outlet holes 16 are connected by another pressure regulating valve. The inlet 15-1 and outlet 16-1 are connected to an external hydraulic oil cooling pipe. Thus, the retarder works, due to the existence of the curved concave surface, the vicinity of the oil inlet hole 15 is a low pressure area of the hydraulic oil, and the low pressure area sucks the hydraulic oil from the outside. Near the oil outlet hole 16 is a hydraulic oil high pressure zone, and the high pressure zone inputs hydraulic oil inwardly, and generates resistance to prevent the blade and the rotor from rotating. During the operation of the retarder, the hydraulic oil in the two curved concave surfaces 14 is internally circulated through the oil outlet, the pressure regulating valve and the oil inlet hole, and the external cooling cycle is performed through the inlet 15-1 and the outlet 16-1.

[25] The housing 11 is provided with an annular through hole 11-1 which is open at both ends, and correspondingly, the front cover 12 and the rear cover 13 are respectively provided with annular grooves 12-1 and 13-1 which are open at one end, The housing 11, the front cover 12 and the rear cover 13 are assembled to form an annular closed cavity 17 in which the first and the ends are not in communication. The rear cover 13 is provided with a water inlet 18 and a water outlet 19, and the water inlet 18 and the water outlet 19 communicate with the leading end and the trailing end of the annular sealed cavity 17, respectively. The water inlet 18 on the rear cover 13 is connected to the water outlet of the automobile water tank by a water pump or directly, and the water outlet 19 on the rear cover 13 is connected to the water inlet of the automobile water tank. A connecting post 21 with a screw hole is respectively disposed in the annular through hole 11-1 in the housing 11, the annular groove 12-1 on the front cover 12, and the annular groove 13-1 on the rear cover 13 respectively. The housing 11, the front cover 12 and the rear cover 13 are connected by screws. Working, the water pump draws water from the tank into the annular closed cavity, and the water circulates in an "S" shaped path in the annular closed cavity. When the braking structure of the brake 吋 retarder is warmed After the degree is increased, the temperature of the circulating water is rapidly reduced to a normal level by heat exchange with the brake structure, and the temperature is kept stable, so that accidents can be effectively avoided. At the same time, it is also possible to avoid the operation of the retarder at high temperatures in the long turns, which can extend the life of the retarder.
