Abstract
The invention relates to an accurately-adjusted brake. A brake shoe (7) is connected with an adjustment quantity display eccentric shaft (8); the adjustment quantity display eccentric shaft (8) is connected with a brake disc (6); an accurately-positioned brake drum (9) is connected with a brake plate (10); the brake plate (10) is connected with the brake shoe (7); a compression wheel (11) is contacted with two brake shoes (7); and the two ends of a spring (12) are connected with the two brake shoes (7). The accurately-adjusted brake has the advantages that: the entire driven brake plate can be tightly pressed on the brake drum and brakes as required during adjustment according to displayed graduation; the brake plate is fully separated from the brake drum when the brake is not driven to return; harmful friction is avoided; deviated braking phenomenon is avoided; and the problems of non-uniform stress of the brake plate, over high local pressure intensity, over high temperature, quick damage and brake failure are solved.
Description
One, technical field
The invention belongs to a kind of break, be specifically related to a kind of accurate adjustment type break.
Two, background technique
At present, the drum brake that various vehicles use, its principle is substantially the same with structure, the device of generation pressure has air pressure, have oil pressure or the like, these pressure unit can provide enough pressure to satisfy needed pressure between braking plate and the brake drum.Because space and structural restriction make braking plate produce the drive unit of motion, its stroke is very limited, and the gap between braking plate and the brake drum be cannot see, and the difficulty of debugging is very big.If it is suitable that the gap between braking plate and the brake drum is adjusted, when drive unit drives braking plate, but the braking plate full wafer is pressed on the brake drum tightly, produce good braking effect, when drive unit no longer drives braking plate, braking plate return then, braking plate separates fully with brake drum.If it is improper that the gap between braking plate and the brake drum is adjusted, braking plate still can not be pressed on the due braking effect of generation on the brake drum by full wafer when sometimes drive unit drove braking plate to limit position; Sometimes drive unit drives a little, but braking plate just full wafer is pressed on and produces braking effect on the brake drum, but drive unit no longer drives braking plate, vehicle when not needing to brake, and braking plate can't separate fully with brake drum, still have certain pressure, produce harmful friction.
Three, summary of the invention
Purpose of the present invention is exactly the problem at above-mentioned existence, a kind of accurate adjustment type break is provided, it has adopted accurate scale sign, and the relative position of braking plate and brake drum is presented on the brake disc, promptly knows the gap of braking plate and brake drum by the scale registration.
The present invention is achieved by the following technical solutions: a kind of accurate adjustment type break, comprise brake disc 6, brake shoe 7, braking plate 10, it by connecting sheet 1, connecting sheet nut 2, pinch roller connecting rod 3, connecting rod nut 4, eccentric shaft nut 5, brake disc 6, brake shoe 7, show adjustment amount eccentric shaft 8, accurately locate brake drum 9, braking plate 10, pinch roller 11, spring 12 and form; Connecting sheet 1 is connected with pinch roller connecting rod 3, connecting sheet nut 2 is connected with pinch roller connecting rod 3 with connecting sheet 1, pinch roller connecting rod 3 is connected with pinch roller 11, connecting rod nut 4 is connected with brake disc 6 with pinch roller connecting rod 3, eccentric shaft nut 5 is connected with demonstration adjustment amount eccentric shaft 8 with brake disc 6, brake shoe 7 is connected with showing adjustment amount eccentric shaft 8, show that adjustment amount eccentric shaft 8 is connected with brake disc 6, accurately location brake drum 9 is connected with braking plate 10, braking plate 10 is connected with brake shoe 7, pinch roller 11 contacts with two brake shoes 7, and the two ends of spring 12 are connected with two brake shoes 7.
The invention has the beneficial effects as follows: adopted accurate scale sign, the relative position of braking plate and brake drum is presented on the brake disc, promptly known the gap of braking plate and brake drum by the scale registration.During adjustment, as long as the braking plate to the break both sides is adjusted identical scale, just can make the braking plate of break both sides reach consistent with the gap of brake drum, adjust with same way again, make the braking plate and the brake drum of vehicle two side brakes all have on all four gap, produce on all four braking effect in the vehicle both sides, the problem of braking does not partially take place.Adjust according to the scale registration and can brake on demand when braking plate is driven, do not take place that braking plate unbalance stress local pressure is excessive, the phenomenon of the too high quick damage of temperature, brake failure, braking plate did not separate fully with brake drum when braking plate was not driven return, did not produce harmful friction.

Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is a right elevation of the present invention.
Five, embodiment
A kind of accurate adjustment type break, it by connecting sheet 1, connecting sheet nut 2, pinch roller connecting rod 3, connecting rod nut 4, eccentric shaft nut 5, brake disc 6, brake shoe 7, show adjustment amount eccentric shaft 8, accurately locate brake drum 9, braking plate 10, pinch roller 11, spring 12 and form; Connecting sheet 1 is connected with pinch roller connecting rod 3, connecting sheet nut 2 is connected with pinch roller connecting rod 3 with connecting sheet 1, pinch roller connecting rod 3 is connected with pinch roller 11, connecting rod nut 4 is connected with brake disc 6 with pinch roller connecting rod 3, eccentric shaft nut 5 is connected with demonstration adjustment amount eccentric shaft 8 with brake disc 6, brake shoe 7 is connected with showing adjustment amount eccentric shaft 8, show that adjustment amount eccentric shaft 8 is connected with brake disc 6, accurately location brake drum 9 is connected with braking plate 10, braking plate 10 is connected with brake shoe 7, pinch roller 11 contacts with two brake shoes 7, and the two ends of spring 12 are connected with two brake shoes 7.
