The invention discloses a trailer axle brake air-cooled retarder device. According to the technology, a tire (1), an axle (2), a transmission half shaft (12), a differential mechanism assembly (13), an electromagnetic clutch (4), a piston air pump assembly (7), a gas storage cylinder (14) and other devices are adopted; the trailer axle utilizes reverse transmission inertia power during downhill running to drive the piston air pump assembly (7) to generate high-pressure gas; the gas enters the gas storage cylinder (14) through a high-pressure gas inlet pipe (10); a high-pressure air outlet pipe(15) arranged on the air storage cylinder (14) is communicated with a high-pressure spray pipe (17) arranged on a rear dustproof baffle (16); high-pressure gas is sprayed into a brake drum inner chamber (19) through a high-pressure spray pipe nozzle (20) arranged in the brake drum inner chamber; and braking high temperature generated during braking is taken away from the edge of a brake drum. Bymeans of the device, for deceleration and slowing down of an inertial vehicle running downhill, the original water spraying cooling technology is replaced with the high-pressure air cooling technology, and therefore the safety and reliability of a brake system in the running process of the vehicle are guaranteed.

    一种挂车车桥制动气冷缓速器装置,该技术通过轮胎(1)、车桥(2)、传动半轴(12)、差速器总成(13)、电磁离合器(4)、活塞气泵总成(7)、储气筒(14)等装置,提供一种挂车车桥利用下坡时反传动惯性动力,驱动活整气泵总成(7)产生的高压气体,通过高压进气管(10)进入储气筒(14),而设置在储气简(14)上的高压出气管(15)与设置在后防尘档板(16)上的高压喷管(17)连通,高压气体通过设置在制动鼓内室高压喷管喷头(20)喷入制动鼓内室(19),将制动鼓内室(19)制动时所产生的制动高温从制动鼓边缘带走,该装置对行驶下坡时的惯性车辆造成减速、缓速,高压气冷技术取代原有淋水降温技术,以保证制动系统在汽车行驶中的安全性、可靠性。
