Bidirectional intelligent automobile clutch driven disc with composite sleeve core

Abstract

A bidirectional intelligent automobile clutch driven disc with a composite sleeve core comprises a rotating shell made of bearing steel and a force transmission frame formed by punching an alloy steel plate. The spline face of the rotating shell is connected with a spline hole of the force transmission frame. The diameter of each auxiliary spring steel wire is larger than the diameter of each main spring steel wire. Each auxiliary spring is mounted in an inner hole of a corresponding main spring, and locating core columns are mounted in holes of the auxiliary springs. The two ends of each locating core column are riveted to the edges of a corresponding fan-shaped hole of the force transmission frame. The main springs are placed in clamping grooves of a right disc chuck and a left disc chuck. A cavity core is arranged in the rotating shell and an inner cavity of a rotating shell cover, and the surface of the cavity core is provided with multiple sections of reducing curved surfaces. Two pairs of thrust bearings are composed of ball grooves of the rotating shell, ball grooves of the rotating shell cover, ball grooves in the two end faces of the cavity core, a plurality of ceramic balls and separation columns with the same number with the ceramic balls, and the metal separation columns are hollow cylinders and are filled with lubricating grease. The right disc chuck and the left disc chuck are connected through pins. According to the bidirectional intelligent automobile clutch driven disc, gear shifting operation is simplified, when an automobile goes down a slope, good braking performance is achieved, and the service life of an engine and the service life of a gearbox can be prolonged.

Description

technical field [0001] The invention relates to a clutch device for an automobile engine, in particular to a driven disk for a bidirectional intelligent composite sleeve core automobile clutch. Background technique [0002] As we all know, the clutch of a car is installed on the flywheel of the engine, and the output shaft of the clutch is the input shaft of the gearbox. During the driving process of the car, the driver can step on or release the clutch pedal according to the road conditions and speed requirements, and manipulate the separation and separation between the driving disc and the ring surface of the pressure disc of the engine and the double-body friction ring of the clutch driven disc. Combination, so that they can be separated in time, and can be gradually combined. In the process of transmitting power, differential transmission is also allowed, and the engine can be cut off or connected to transmit torque to the gearbox. Cars equipped with manual transmission...

Problems solved by technology

But this clutch driven disc has its important shortcoming, and this shortcoming is: when the car runs on the downhill road for a long time, the car is driven by the component of motion inertia and gravity. The component is applied to the car with a nearly constant force all the time. For the car, the speed is increased in the form of acceleration, and the speed of the car will continue to increase. Because the function of the overrunning clutch is one-way locking Driven, so that the car is equivalent to walking on a slope in neutral gear. At this time, the car's walking system and the engine are in a state of separation, resulting in an increase in the burden on the braking system: the engine's connection drag will provide part of the braking capacity of the car's walking system

Especially for heavy-duty trucks, when they go downhill for a long time in neutral gear and only rely on the brake system to brake, it is very easy to cause the contact parts of the brake system to overheat, burn in red, reduce the stiffness and strength of the brake parts, and even cause the brake system to fail. Major accidents of vehicle damage are prone to occur, and drivers and passengers will be seriously injured and even lose their precious lives.
