Description

A kind of semi-axis structure of integrated revolving speed gear ring
Technical field
The invention belongs to automobile drive axle fields, and in particular to a kind of semi-axis structure of integrated revolving speed gear ring.
Background technique
In domestic drive axle, the gear ring for measuring vehicle wheel rotational speed is mounted on wheel hub more, gear ring and wheel hub press-fit;Using Sensor support structure positions speed probe, and signal is acquired from gear ring.Such structure, increases gear ring and sensor stand Production cost, and gear ring and speed probe are arranged in the inside of brake drum and brake, are unfavorable for observing and adjust, reduce The reliability of signal acquisition.
Summary of the invention
The present invention is to solve in existing drive axle, since gear ring is mounted on wheel hub, increases the production cost and peace of gear ring Dress up this;Due to using sensor support structure, increase the production cost of sensor stand;Due to gear ring and speed probe cloth The inside in brake drum and brake is set, the problems such as observing and adjusting, reduce the reliability of signal acquisition is unfavorable for.One kind is provided The semi-axis structure of integrated revolving speed gear ring, reduces cost, promotes reliability.
The present invention is achieved by the following technical scheme:
A kind of semi-axis structure of integrated revolving speed gear ring, including semiaxis, axle case assy, speed probe;Semiaxis is packed into axle housing Assembly, semiaxis one end and axle shaft gear are keyed, and the other end is connect by ring flange with boss bolt;Speed probe screw thread connects It connects on axle case assy, revolving speed gear ring is integrated on the diameter of axle of semiaxis, speed probe is corresponding with revolving speed gear ring position, and revolving speed The tooth top of sensor base end face and revolving speed gear ring keeps standard clearance;Gasket is equipped between axle case assy and speed probe.
Further, the revolving speed gear ring integrated on the semiaxis diameter of axle is the distribution tooth form of arc tooth socket.
Further, the axle case assy side is equipped with cylindrical boss, and gasket is mounted on cylindrical boss, cylindrical Tapped through hole is processed on boss, for installing speed probe.
Further, the speed probe bottom is equipped with probe, and probe is matched with the revolving speed gear ring tooth form on the semiaxis diameter of axle It closes, probe and the tooth top of revolving speed gear ring is made to keep standard clearance;Connector structure is equipped at the top of speed probe, for transmitting letter Number.
Compared with prior art the beneficial effects of the present invention are:
A kind of semi-axis structure of integrated revolving speed gear ring is integrated with revolving speed gear ring structure on semiaxis, eliminates and be mounted on wheel hub On gear ring, reduce costs;Speed probe is screwed on axle case assy, is eliminated sensor support structure, is reduced into This;Speed probe is mounted on the position for being easy to detect, and improves the reliability of signal acquisition.
