Description
Technical field
This utility model belongs to auto parts machinery field, is specifically related to a kind of drum brake for automobile brake.
Background technology
Drum brakes is applied in above automobile nearly centurial history, but reliability and the powerful brake force due to it, drum brakes is still arranged in many vehicles now and (is used in trailing wheel more), drum brakes is the past extrapolation of brake block that will be installed in brake rim by hydraulic pressure, make brake block and the inner face along with the brake rim of vehicle wheel rotation rub, and produce the effect of brake.Currently there are a lot of disk brake, but the brake weight of disk type brake relatively drum brakes is low；Little compared with drum brakes of friction area between brake block and brake disc, the strength making brake is also smaller；Lever brake is not easily installed；The abrasion of brake block is relatively big, causes replacement frequency and is likely to higher.
Utility model content
The purpose of this utility model is that provides a kind of drum brake for automobile brake to solve the problems referred to above.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of drum brake for automobile brake, including brake drum, back-plate, brake block, brake rim, brake rim bosom is connected to rotation axle, rotate both sides outside axle and be connected to brake drum, it is connected to alignment pin between brake drum lower tip, brake drum upper end is connected to wheel cylinder, wheel cylinder is arranged below back-moving spring, brake drum rear is provided with back-plate, brake rim rear is provided with hydraulic oil pump, lining it is fixed with outside brake drum, brake rim inner surface is close to brake block, brake rim rear is provided with push rod, push rod is arranged below hydraulic oil pipe.
In said structure, drum brakes is exactly utilize brake block static in brake rim, go friction along with the brake rim of vehicle wheel rotation, with produce frictional force turn a wheel speed reduce, when stepping on brake pedal, the force of foot can make the piston in brake hydraulic oil pump brake fluid be pushed forward and produce pressure in oil circuit, pressure is sent to the wheel cylinder of each wheel via brake fluid, the piston of wheel cylinder promotes brake block outside again, the inner face making brake block and brake rim rubs, and produce enough frictional force go reduce wheel rotating speed, to reach the purpose of brake.
In order to improve brake effect further, rotating axle and fixed by bearings with rotating axle, brake drum is connected by axle sleeve with rotating axle.
In order to improve brake effect further, the brake drum of both sides is connected by alignment pin and wheel cylinder, and brake drum is connected by screw is fixing with back-moving spring.
In order to improve brake effect further, back-plate and brake rim are by being welded and fixed, and brake drum and lining are by being adhesively fixed.
In order to improve brake effect further, hydraulic oil pump and brake rim are fastenedly connected by screw, and wheel cylinder is connected by hydraulic oil pipe with hydraulic oil pump.
Have the beneficial effects that: the use that this brake has automatic brake tight, make brake system can use relatively low oil pressure, or use diameter than brake disc little a lot of brake rim；The installation of hand brake mechanism is easy；The processing of part is relatively simple with composition, and has comparatively cheap manufacturing cost.
Accompanying drawing explanation

Fig. 2 is the left view of the drum brake for automobile brake described in the utility model.
1, axle is rotated；2, brake drum；3, back-moving spring；4, wheel cylinder；5, back-plate；6, hydraulic oil pump；7, lining；8, brake block；9, alignment pin；10, brake rim；11, push rod；12, hydraulic oil pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
nullAs Figure 1-Figure 2，A kind of drum brake for automobile brake，Including brake drum 2、Back-plate 5、Brake block 8、Brake rim 10，Brake rim 10 bosom is connected to rotation axle 1，Wheel hub is driven to rotate，Rotate both sides outside axle 1 and be connected to brake drum 2，Push away vehicle cover and carry out frictional damping with brake block 8，It is connected to alignment pin 9 between brake drum 2 lower tip，Connect brake drum 2，Brake drum 2 upper end is connected to wheel cylinder 4，Brake drum 2 is promoted to move，Wheel cylinder 4 is arranged below back-moving spring 3，Auxiliary braking drum 2 returning quickly，Brake drum 2 rear is provided with back-plate 5，Support brake drum 2 and brake block 8，Brake rim 10 rear is provided with hydraulic oil pump 6，Produce power，Lining 7 it is fixed with outside brake drum 2，Brake rim 10 inner surface is close to brake block 8，Frictional damping is carried out with wheel hub，Brake rim 10 rear is provided with push rod 11，Push rod 11 is arranged below hydraulic oil pipe 12，Discharge pressure oil.
In said structure, drum brakes is exactly utilize brake block 8 static in brake rim 10, go friction along with the brake rim 10 of vehicle wheel rotation, with produce frictional force turn a wheel speed reduce, when stepping on brake pedal, the force of foot can make the piston in brake hydraulic oil pump 6 brake fluid be pushed forward and produce pressure in oil circuit, pressure is sent to the wheel cylinder 4 of each wheel via brake fluid, the piston of wheel cylinder 4 promotes brake block 8 outside again, the inner face making brake block 8 and brake rim 10 rubs, and produce enough frictional force go reduce wheel rotating speed, to reach the purpose of brake.
In order to improve brake effect further, rotate axle 1 and fixed by bearings with rotating axle 1, brake drum 2 is connected by axle sleeve with rotating axle 1, the brake drum 2 of both sides is connected by alignment pin 9 and wheel cylinder 4, brake drum 2 is connected by screw is fixing with back-moving spring 3, and back-plate 5 and brake rim 10 are by being welded and fixed, and brake drum 2 and lining 7 are by being adhesively fixed, hydraulic oil pump 6 and brake rim 10 are fastenedly connected by screw, and wheel cylinder 4 is connected by hydraulic oil pipe 12 with hydraulic oil pump 6.
Of the present utility model ultimate principle, principal character and advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model.This utility model claims scope and is defined by appending claims and effect thing thereof.
