The invention provides an automobile drive disc assembly, which includes a drive disc body, a starting ring gear, a signal tooth, a flange and a pressure plate. The starting ring gear is fixedly connected with the drive disc body, and the signal teeth are directly stamped on the outer peripheral wall of the drive disc body, and are integrated with the drive disc body, and the signal teeth are formed on the outer peripheral wall of the drive disc body. Evenly distributed on the top and perpendicular to the plane of the disc body, and two teeth are continuously removed from all the teeth, as a benchmark for judging the crankshaft timing phase. The flange plate and the pressure plate clamp the drive disc body in the middle, and the present invention directly stamps out the signal teeth on the drive disc body, and the integrated design of the signal teeth and the disc body avoids the trouble of secondary positioning. The matching accuracy of the sensors is higher, the accuracy and reliability of signal collection are improved, and the manufacturing cost is reduced. The introduction of the flange greatly improves the generalization rate of the key component crankshaft, and the central positioning hole is easier to process and the cost is lower.

The invention discloses an adjustable wheel speed sensor, which includes a wheel hub and a wheel speed sensor. The wheel speed sensor includes a wire harness end, a head threaded rod, an installation fixing rod and a sensor body. The head threaded rod is a hollow structure, and its interior is There are internal threads, the sensor body is fixed on one end of the head threaded rod; one end of the fixed rod is provided with a telescopic groove, and an adjusting screw is arranged in the telescopic groove, and the other end of the head threaded rod is embedded in the telescopic groove and threadedly connected with the adjusting screw , so that the head threaded rod is telescopically connected with the installation and fixing rod, the interior of the adjusting screw is provided with a through harness hole, and the end of the harness passes through the harness hole and is connected to the sensor body; the bottom plate of the brake is provided with a connecting hole, and the head threaded rod Can be embedded in the connection hole. The invention can be applied to different car models, reduces the types of wheel speed sensors, improves the generalization rate, reduces development costs and shortens the development period.

The invention discloses a water tank module with selectable water channels and a washing machine thereof, comprising a water channel plate provided with water channels, at least one water channel is provided with a water channel clip, and the water channel is blocked by the water channel clip or selected to conduct different water channels. When producing washing machines, different washing machines can share the same water tank module. By selecting different water channel clips to cooperate with bayonet sockets at different positions, the water channel can be blocked or different water channels can be selected to conduct different water channels to realize different washing machine functions. The water tank module improves the generalization rate of parts, reduces the cost, improves the production efficiency, and is simple to operate and easy to realize, and the water tank module is unified.
