Embodiment Construction

[0046] Such as figure 2 As shown, a three-point side-mounted hoof-drum type gap independent limit self-adjusting instantaneous center brake consists of a brake base plate 1, upper and lower supporting shoe shafts 2, 2', upper and lower brake shoes 3, 3' , Upper and lower ratchet conjoined double working surface cam 4, 4', upper and lower positioning pawls 5, 5', upper and lower positioning pawls 6, 6', camshaft 7, pawl spring 8, pawl spring The positioning cover 9, the upper and lower positioning ratchet Xiao shafts 10, 10 ', the upper and lower positioning ratchet Xiao shafts 11, 11' are composed. The upper and lower support shoe shafts 2, 2' are fixed in the bearing hole of the brake base plate 1, and the upper and lower support shoe shafts 2, 2' are symmetrical to each other and are placed on both sides of the horizontal axis of the brake base plate 1. The upper and lower support shoe shafts 2, 2' are equipped with upper and lower brake shoes 3, 3', and upper and lower ra...

Abstract

The present invention belongs to a three-force side shoe drum type clearance independence spacing self regulating instantaneous center brake for auto wheel. The characteristics of the invention is the bearing hole of the braking base plate fixes upper, lower supporting shoe pin roll, mutually symmetrical and locating on the two sides of the horizontal axis, the upper and the lower supporting hoof pin roll are packed with an upper and lower brake shoes, the upper and lower bearing holes of the upper and lower brake shoes are set with the upper and lower ratchet wheel coupling double working surfaces cams; the horizontal axis of the braking base board has a camshaft, the upper and lower bearing shoe pin roll and the camshaft form polarization braking center triangle; the upper and lower positioning pawl pin rolls are set on the extending part of the upper and lower braking shoes, the upper and lower locating pawl bearing hole is set on the braking plate, the claw is connected to the ratchet tooth. The invnetion acquires small abrasion of the brake braking working surface, having no noise, realizing optimal braking time, optimal braking deceleration, optimal braking distance, maximum force value and optimal force balancing effect, ensuring auto operating safety.

Description

technical field [0001] The invention belongs to vehicle control brakes, in particular to an independent position-limiting self-adjusting instantaneous center brake used for three force points on automobile wheels and side-mounted hoof-drum type gaps. Background technique [0002] As a means of transportation invented by human beings with its own ability to move, automobiles are used in all related fields of human social and economic activities, such as transportation, agriculture, mining, petroleum, hydropower, forestry, coal, construction, medical care, culture and education, fire protection, military, In the development of the universe, all occupy a certain position. However, when the number of automobiles in the world is increasing sharply every year by tens of millions, it has brought unexpected disasters to human beings—car accidents. [0003] There are many reasons for traffic accidents, such as unlicensed driving and drunk driving; poor road conditions; changes in na...
