Problems solved by technology

When this type of device brakes, it relies on the friction between the friction plate and the wheel hub to convert kinetic energy into heat energy to achieve the purpose of braking. When driving on a heavy vehicle or a long downhill road, the phenomenon of "thermal failure" will occur, resulting in car crashes and fatalities. Major traffic accidents, and the torque transmitted during braking is small, so the braking is slow; when the device with this structure is used to transmit power in linkage, there are also phenomena such as small transmitted torque, damage to the friction surface, and "thermal failure"
In short, the existing friction disc brake or linkage device has the disadvantages of unreliable use, small transmission torque, poor economy, and is not suitable for use on high-power devices. The friction disc needs to be replaced after a period of use

Embodiment Construction

[0017] As shown in Figures 1 and 3, the braking device is composed of two separate working parts, the working surfaces of which are opposite. The working surface of the rotating part 7 has a concave surface 8 and a convex surface 9 arranged alternately. (rotating shaft is not drawn in the figure), the other work piece is fixed, and its working surface is equipped with a series of rollers 5 through the wheel frame 6, and the roller shaft 4 is equipped with rolling bearings, and is connected to the base 3 on the working surface One end of the push rod 2 in the telescopic press cylinder body 1, the pressure transmission medium in the cylinder body 1 can use hydraulic oil or compressed air, and the direction of the push rod 2 is coaxial with the rotating shaft of the rotating member 7. When braking, the push rod 2 presses the roller 5 to the concave surface 8 and the convex surface 9, and the friction force generated on the contact surface is very small, so there is little heat, an...

Abstract

The invention relates to a rough-surface braking and linkage device and belongs to a power transmission device for machinery power, in particular to the braking or linkage device of machinery. The device consists of two working parts which are mutually separated; and the working surfaces of the two working parts are arranged opposite to each other. One working surface is provided with curved surfaces that are spaced in convex and concave arrangement; and the other working surface is provided with a roller. And a base of the working surface is connected with a telescopic pressure-cylinder push rod which is in a same axial direction with a rotary part. The invention has the advantages of simple structure, no wearing, no heating on the combined surface when braking or linkage and large transmission moment.

Description

technical field [0001] The invention belongs to a mechanical power transmission device, in particular to a mechanical braking or linkage device. Background technique [0002] The current separation brake / linkage mechanism generally adopts a friction plate structure, for example, such a friction plate brake or linkage device can be seen on the hub brake device of an automobile and the clutch of an automobile. When this type of device brakes, it relies on the friction between the friction plate and the wheel hub to convert kinetic energy into heat energy to achieve the purpose of braking. When driving on a heavy vehicle or a long downhill road, the phenomenon of "thermal failure" will occur, resulting in car crashes and fatalities. Major traffic accidents, and the torque transmitted during braking is small, so the braking is slow; when the device with this structure is used to transmit power in linkage, there are also phenomena such as small transmitted torque, damage to the f...
