Abstract
The utility model relates to a full-sealed piston type spring brake cylinder assembly. The full-sealed piston type spring brake cylinder assembly is characterized in that a gas chamber of the spring brake cylinder assembly is communicated with a balancing cavity of a spring cylinder by the aid of an internal breathing pipe, a pipe joint is mounted on a portion, which is located on the gas chamber, of a casing of the balancing cavity, and a waterproof protecting sleeve is added to a push rod of the service braking gas chamber. During wading of a vehicle, the full-sealed piston type spring brake cylinder assembly prevents water from entering the service braking gas chamber and the balancing cavity of the spring cylinder to affect braking performance, and prevents dust and sand from entering the gas chamber and the balancing cavity of the spring cylinder to affect service lives of springs and membranes so as to further cause failure, thereby improving wading performance and off-road capacity of the vehicle.
Description
Technical field
The utility model relates to a kind of hermetically sealed piston type spring brake cylinder assembly, in belonging to, the technical field of heavy off-road vehicle air braking system.
Background technique
Characteristics such as at present typical spring brake cylinder is simple in structure with it, volume is less, adaptive capacity to environment is stronger are adopted by most motor corporations.But in, have the following defective in the using process of heavy off-road vehicle: because the structure design characteristic of traditional spring brake cylinder assembly is an open type, the unshielded measure of counter balance pocket that air chamber and the spring cylinder part of promptly driving a vehicle communicates with atmosphere, counter balance pocket part directly on body perforate communicate with atmosphere, it is mobile that the variation that the elastomer diaphragm back space takes place produces air, will bring dust, the grains of sand, water etc. into influences spring and diaphragm life-span, and then causes inefficacy; Under the situation of paddling, water is discharged difficulty and is influenced braking ability after entering into this chamber.
Summary of the invention
The purpose of this utility model is to provide a kind of hermetically sealed piston type spring brake cylinder assembly, with the diameter that communicates with atmosphere at present typical spring brake cylinder service brake air chamber and the spring cylinder assembly counter balance pocket housing is 4 balance pore cancellations of 5mm, in vehicle is paddled process, prevent that dust, the grains of sand, water from entering in the counter balance pocket of service brake air chamber and spring cylinder, improved fordability, the cross-country power of vehicle.
The technical solution of the utility model is achieved in that hermetically sealed piston type spring brake cylinder assembly; it is characterized in that: the air chamber of spring brake cylinder assembly is communicated with the internal respiration pipe with the counter balance pocket of spring cylinder; mounting pipe joint on the air chamber partial equilibrium cavity shell, service brake air chamber push rod place increases waterproofing guaranteeding jacket.
The utility model good effect is that anti-sealing enters in the counter balance pocket of service brake air chamber and spring cylinder, influences braking ability in vehicle such as paddles at process; Prevent that dust, the grains of sand from entering the counter balance pocket some effects spring and the diaphragm life-span of air chamber and spring chamber, and then cause inefficacy; Fordability, the cross-country power of vehicle have been improved.
Description of drawings
Fig. 1 is the structural representation of hermetically sealed piston type spring brake cylinder assembly.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further: hermetically sealed piston type spring brake cylinder assembly
It is characterized in that: the air chamber of spring brake cylinder assembly is communicated with the internal respiration pipe with the counter balance pocket of spring cylinder, mounting pipe joint on the air chamber partial equilibrium cavity shell, and service brake air chamber push rod place increases waterproofing guaranteeding jacket.
Air chamber is communicated with internal respiration pipe 1 with the counter balance pocket of spring cylinder, with the diameter that communicates with atmosphere on the brake chamber counter balance pocket housing is 4 balance pore cancellations of 5mm, counter balance pocket housing mounting pipe joint 2 connecting pipelines are drawn out to more than the vehicle fording depth, communicate with atmosphere then.Brake chamber push rod place increases waterproofing guaranteeding jacket 3, in vehicle is paddled process, prevents that dust, the grains of sand, water from entering in the counter balance pocket of service brake air chamber, has improved fordability, the cross-country power of vehicle.
