At present, the market discloses such a wet brake, and its structural feature is: the brake cylinder consists of a plurality of dynamic friction plates, a plurality of static friction plates, a plurality of springs, a brake cylinder cover, a brake piston, a brake cylinder body, a brake shell, a wheel core and a cover plate, wherein the dynamic friction plates and the static friction plates are arranged in parallel at intervals, a tooth-shaped spline is arranged in an inner hole of the brake cylinder body, a tooth-shaped spline is also arranged on the excircle of the static friction plate, the static friction plates are arranged on the tooth-shaped spline in the brake cylinder body to form a whole, the inner hole of the tooth-shaped spline of the dynamic friction plates is connected with an outer spline at one end of the wheel core into a whole, the other end of the wheel core is connected with a tire, one end of the brake piston arranged in the brake shell is contacted with the dynamic friction plates or the static friction plates, the other end of the brake piston is contacted with the brake cylinder cover through the plurality of springs, the cover plate is sleeved on the wheel core and is connected with one end of the brake cylinder body, but only one oil seal for preventing internal oil from leaking outside is arranged between the wheel core and the cover plate, when the vehicle runs on a road with poor road conditions, muddy water is easy to enter the dynamic friction plate and the static friction plate through the joint between the wheel core and the cover plate, the braking performance is damaged, and the driving safety is affected.
Disclosure of Invention
The utility model aims to provide an amphibious wet brake which can effectively prevent muddy water from entering a dynamic friction plate and a static friction plate and ensure driving safety.
In order to achieve the purpose, the amphibious wet brake comprises a plurality of dynamic friction plates, a plurality of static friction plates, a plurality of springs, a brake cylinder cover, a brake piston, a brake cylinder body, a brake shell, a wheel core and a cover plate, wherein the dynamic friction plates and the static friction plates are arranged in parallel at intervals, a tooth-shaped spline is arranged in a hole in the brake cylinder body, the outer circle of each static friction plate is also provided with the tooth-shaped spline, the static friction plates are arranged on the tooth-shaped spline in the brake cylinder body to form a whole, an inner hole of the tooth-shaped spline of each dynamic friction plate is connected with an outer spline at one end of the wheel core into a whole, the other end of the wheel core is connected with a tire, one end of the brake piston arranged in the brake shell is contacted with the dynamic friction plates or the static friction plates, the other end of the brake piston is contacted with the brake cylinder cover plate through the springs, the cover plate is sleeved on the wheel core and is connected with one end of the brake cylinder body, and one end, which faces outwards, is also provided with an oil seal seat, an oil seal is arranged in the oil seal seat.
The oil seal seat is arranged to be annular, a groove capable of containing an oil seal is formed in the surface of an inner hole of the oil seal seat, and a plurality of holes convenient for bolts to penetrate are formed in the end face of the oil seal seat.
After the structure is adopted, because the outward end of the cover plate is also provided with the oil seal seat, an oil seal is arranged in the oil seal seat. Two oil seals are arranged between the wheel core and the cover plate, so that the internal oil is prevented from leaking, and external muddy water can be prevented from flowing into the front oil seal, so that the aims of effectively preventing muddy water from entering the dynamic friction plate and the static friction plate and ensuring driving safety are fulfilled.
