The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model embodiment is described in further detail below in conjunction with accompanying drawing.
As with the diverse air braking system of oil-air braking system, its system works principle is: glancing impact, Pneumatic pipe cleaner in the source of the gas is crossed pipeline system and is delivered in the compressed air brake cylinder that is installed on the air chamber support, by the compressed air brake cylinder effect air pressure is converted into kinetic energy, the motion of promotion braking adjusting arm, the straight-line motion of braking adjusting arm actuating cam axle again rotates, and contacts thereby brake shoe brake cheek is opened with brake wheel, reaches the purpose of braking; During brake off, the gas in the compressed air brake cylinder is directly got rid of, the brake shoe brake cheek playback.From the system works principle as can be seen, the major tasks position of this air braking system is a compressed air brake cylinder, it is bearing the effect that system's air pressure is converted into kinetic energy, so the air chamber support installation bearing piece of compressed air brake cylinder still not, also bears the braking reaction thrust in the work.
Because existing air braking system all uses on the light-duty vehicle chassis of no wheel reduction gear, its air chamber support is installed on the vehicle bridge of wheel inboard, simultaneously to strong point of camshaft, makes camshaft can bear enough big thrust and does not deform.But there are not enough installing spaces near independent suspension system being installed, adopting the breakaway-element bridge and being had the extra heavy off road vehicle wheel of wheel reduction gear, can't be directly installed on the air chamber support on the bridge or other positions of lateral wheel, also can't provide support for camshaft, therefore structure design emphasis of the present utility model is the mounting means that solves compressed air brake cylinder, and consider its with adjusting arm, camshaft between be connected, and then provide the failure-free lock torque for car load.
The utility model has adopted the rational structure pattern, be that the air chamber support is installed on the wheel hub, reach reliable purpose of connecting by lengthening and reinforcement camshaft, solved the wheel braking air chamber that major diameter, high width wheel hub are installed a difficult problem is installed, make the car load brake system reach the necessary technology index.
Different with non-bogie wheel configuration at the cross-country car wheel flutter, the utility model has designed two kinds of air braking system air chamber rack mounting structures that structure is slightly different.
