The invention relates to an automobile electric power-assisted braking short rack. The automobile electric power-assisted braking short rack comprises a rack body, an annular baffle arranged on one side of the rack body, an annular table, a riveting groove, a mounting table, a locking ring embedded in the riveting groove and a circular ring arranged on the annular table in a sleeving mode and clamped and fixed between the annular baffle and the locking ring. The riveting groove comprises a groove body formed between the annular table and the mounting table, an annular wedge-shaped body arranged in the groove body and an embedded conical surface arranged between the annular wedge-shaped body and the mounting table; the annular wedge-shaped body comprises a steep conical surface close to one side of the annular table and a slow conical surface connected with the embedded conical surface. Compared with the prior art, the locking ring is directly pressed into the riveting groove in the assembling process, the circular ring can be pressed tightly at the same time, it is guaranteed that no gap exists between the circular ring and the step of the ring table, the riveting groove can be suitable for generating reliable axial force in the electric power-assisted braking transmission process under most conditions, and the industrial application prospect is large.
本发明涉及一种汽车电动助力制动短齿条,包括齿条本体、设于齿条本体一侧的环形挡板、依次与环形挡板相连接的环台、铆槽及安装台、嵌设于铆槽上的锁紧环,以及套设于环台上并夹紧固定于环形挡板与锁紧环之间的圆环;其中,铆槽包括开设于环台与安装台之间的槽体、设于槽体内的环状楔形体,以及设于环状楔形体与安装台之间的嵌入锥面;环状楔形体包括靠近环台一侧的陡锥面以及与嵌入锥面相连接的缓锥面。与现有技术相比,本发明中在装配时将锁紧环直接压入铆槽内,即可同时压紧圆环,保证圆环与环台台阶无间隙,并且该铆槽能够适用于大多数情况下,电动助力制动传递时产生可靠的轴向力,具有较大的工业应用前景。
