An automobile drive disc assembly

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of automobile engines, and in particular relates to an automobile driving disc assembly. Background technique [0002] The car drive plate is specially used for automatic transmission models. It is used to connect the crankshaft and the torque converter of the AT, transmit the engine torque, and start the engine driven by the starter motor. Due to the structural and functional requirements of some drive discs, crankshaft position teeth need to be arranged on the drive disc so that the sensor can collect crankshaft position signals. [0003] The drive disc assembly introduced by the publication number CN1786522A is composed of a drive disc body, a ring gear, a front cover, and a signal tooth disc body for measuring the position of the crankshaft. The drive disc body is disc-shaped, and the connecting bolts pass through the front cover, and then Pass through the drive disc body and connect to the crankshaft. ...

AI Technical Summary

Problems solved by technology

Because the signal tooth is secondary positioning, this method requires high matching precision of parts, high manufacturing cost and complicated process, and because the signal tooth plate is added separately, the moment of inertia is increased, which affects the transmission efficiency and affects the crankshaft system. The design has had an adverse effect

On the other hand, automatic transmission engines are generally developed on the basis of manual transmission. Due to the limitation of the axial distance from the big end of the crankshaft to the torque converter, the big end of the crankshaft often needs to be redesigned, resulting in unnecessary special parts and mold costs.
