Device for increasing reminder to replace gasket and used for self-adjusting arm

Abstract

The invention provides a device for increasing a reminder to replace a gasket and used for a self-adjusting arm. The device comprises a brake gap adjusting arm, the brake gap adjusting arm is providedwith a shell, a worm, a worm wheel, a pawl assembly, a ratchet assembly, a connecting pipe and a connecting rod mechanism; the connecting rod mechanism includes a connecting rod and a connecting sleeve arranged on the connecting rod in a sleeving manner, and the upper surface of the connecting rod is provided with four circular arc grooves; the side, close to a pin shaft, of the connecting rod isprovided with an alignment groove, remaining three grooves are counting grooves, the counting grooves correspond to three ratchet wheel teeth of a pawl in position, and the connecting sleeve is provided with an alignment hole. According to the device, when a gap between a brake lining and a wheel hub reaches the condition that the gasket needs to be replaced, the reminder is provided for a driver, the adjusting arm cannot be locked, it is ensured that a vehicle can be continuously driven, and the driver can conveniently drives the vehicle to a maintenance point to replace the gasket.

Description

technical field [0001] The invention relates to the technical field of brakes for transmitting rotational motion, in particular to a device for increasing reminders to replace linings on a self-adjusting arm. Background technique [0002] The first thing to explain is that the automatic adjustment arm used in automobiles is technically mature and has been widely used in developed countries in Europe and America for many years without obvious design defects. In terms of the technological content of the product, the automatic adjustment arm has many advantages. It can automatically adjust the best gap between the brake lining and the wheel hub at all times during driving, maintain a good braking effect, and avoid the unevenness of manual adjustment. Drawbacks and hassles. However, when the gap between the brake lining and the wheel hub is very large, when the brake is stepped on, the brake lining cannot forcefully expand and form enough friction with the wheel hub, that is, t...

AI Technical Summary

Problems solved by technology

However, when the gap between the brake lining and the wheel hub is very large, when the brake is stepped on, the brake lining cannot forcefully expand and form enough friction with the wheel hub, that is, the automatic adjustment arm has failed, and the automatic adjustment function is completely lost. There is no prompting device , which poses a serious safety hazard. Although there are some prompting devices on the market, the design is very unreasonable. When the gap between the brake lining and the hub reaches the lining and needs to be replaced, the adjusting arm will be locked, and the vehicle cannot walk. If you encounter special traffic conditions, it will also bring driving hazards
