The invention discloses a coaxial reversing device for two-side hand wheels of a hand brake. Comprising a hand brake, double-side hand wheels, a front hand wheel shaft and a back hand wheel shaft, wherein the back hand wheel shaft is driven by a back hand wheel and is in driving connection with a hand brake driving shaft through a reversing device; the reversing device is a coaxial gear reversing mechanism and is composed of a driven bevel gear, a conversion bevel gear and a driving bevel gear which are arranged in a gear cover. The gear cover is fixed on a bottom shell of the hand brake through a rivet; a shaft hole of the driven bevel gear is sleeved into a driving shaft of the hand brake for driving connection; a bevel gear reversing transmission pair is formed among the driven bevel gear, the conversion bevel gear and the driving bevel gear, and the driving bevel gear is in driving connection with the back hand wheel shaft through an input shaft. According to the reversing device, when the hand brakes on the two sides conduct braking operation, the hand wheels are rotated clockwise; hand wheels of the hand brakes on the two sides are located on the same axis, and symmetrical space structure design and installation on a truck body are met; the transmission efficiency is high and the occupied space is small.

    本发明公开了一种手制动机双侧手轮同轴换向装置。包括手制动机及其配置的双侧手轮和正面手轮轴、背面手轮轴;其中,背面手轮轴由背面手轮驱动、通过换向装置与手制动机主动轴驱动联接;换向装置是同轴齿轮换向机构,由设置于齿轮罩中包括从动锥齿轮、转换锥齿轮和主动锥齿轮构成;齿轮罩通过铆钉固定于手制动机底壳上,从动锥齿轮的轴孔套入手制动机主动轴驱动联接;从动锥齿轮与转换锥齿轮、主动锥齿轮之间形成锥齿轮换向传动副,主动锥齿轮通过输入轴与背面手轮轴驱动联接。本发明换向装置实现在双侧手制动机制动操作时,均为顺时针旋转手轮;双侧手制动机手轮处于同一轴线上,满足货车车体上对称空间结构设计安装;传动效率高,占用空间小。
