Abstract
The utility model relates to the field of automotive brake, in particular to a brake shoe assembly, which aims to warn drivers to timely change a brake shoe facing to enhance driving safety when the brake shoe facing is abraded to a limit position and raises the alarm automatically. To achieve the aim, the brake shoe assembly comprises a brake shoe weld assembly in the shape of a semicircular drum, a brake facing is arranged on the outside of the circumference of the brake shoe weld assembly which is provided with an abrasion indicator, one end of the abrasion indicator is suspended and at the same height with an abrasion limit position of the brake facing, and the other end of the abrasion indicator is connected with a sensor of an electronic control system (ECU) of a vehicle. According to the technique scheme, when the brake facing is abraded to the limit position, the sensor transmits the alarming signal to the ECU of the vehicle to warn a driver to timely change the brake facing, thus driving safety can be effectively enhanced.
Description
Technical field
The utility model relates to the automotive brake field, is specifically related to a kind of brake shoe assembly.
Background technique
At present automotive brake mainly comprises two kinds of disc type brake and drum brake, and wherein drum brake also is block brake, leans on brake shoe to compress on Brake drum and realizes braking.The structure of the drum brake that has now mainly is an internal tensional type, and its brake shoe liner is positioned at the Brake drum inboard, and the brake shoe liner outwards opens in brake, and the inboard perisporium of friction catch wheel reaches the purpose of brake.Yet, in braking process, can assemble a large amount of heats because the heat dispersion of drum brake is poor.Brake shoe liner and wheel hub wear and tear extremely serious under temperatures involved, are easy to generate fading of brake and the phenomenon that flutters, and cause that retardation efficiency descends.The brake shoe gasket wear of present domestic most of drum brake is during to limit position, can only rely on driver's active to remove to observe the abrasion condition of judging the brake shoe liner, because the brake shoe present position is hidden, observe very difficult, security incident very easily appears in detailed rules and regulations if observe not, has reduced traffic safety.
The model utility content
The purpose of this utility model provides a kind of brake shoe assembly, when the brake shoe gasket wear gives the alarm during to limit position automatically, reminds driver in time to change, and improves traffic safety.。
For achieving the above object, the utility model by the following technical solutions, a kind of brake shoe assembly, the brake shoe weld assembly that comprises the semicircle drum type, the week of brake shoe weld assembly is provided with brake lining laterally, the brake shoe weld assembly is provided with wear indicator, and it is concordant with the wear limit position of brake lining that an end of wear indicator is suspend shape and its end, and the wear indicator the other end is connected with the sensor of automobile ECU control system.
By above technological scheme, when brake pad wear arrived limit position, sensor can be delivered to alarm signal the automobile ECU control system, and the prompting driver in time changes brake lining, can effectively improve traffic safety.
Description of drawings
Fig. 1 is the structural representation of this device;
Fig. 2 is the structural representation of wear indicator.
Embodiment
A kind of brake shoe assembly, the brake shoe weld assembly 10 that comprises the semicircle drum type, the week of brake shoe weld assembly 10 is provided with brake lining 20 laterally, brake shoe weld assembly 10 is provided with wear indicator 30, it is concordant with the wear limit position of brake lining 20 that one end of wear indicator 30 is suspend shape and its end, and wear indicator 30 the other ends are connected with the sensor of automobile ECU control system.Connect by lead between the sensor of wear indicator 30 automobile ECU control system.Under the normal condition, wear indicator 20 does not contact with the Brake drum wheel hub, has only when brake lining 20 may wear to limit position wear indicator 30 and the friction of Brake drum wheel hub, at this moment sensor can be delivered to warning sign the automobile ECU control system, sends alarm command.
Described wear indicator 30 comprises straight bar section 31, one end of straight bar section 31 is revealed in the outer end of brake shoe weld assembly 10 and concordant with the wear limit position of brake lining 20, and the other end of straight bar section 31 is kink shape and its termination portion is welded on the brake shoe weld assembly 10.The outer end of brake shoe weld assembly 10 is exactly a side that is provided with brake lining 20 specifically, the termination portion of straight bar section 31 and the concordant normal brake application that can guarantee brake lining 20 in the wear limit position of brake lining 20, only when serious wear, braking effect went down even influence traffic safety, the straight bar section 31 of wear indicator 30 just rubbed with the Brake drum wheel hub.It is in order to dodge other parts on the brake shoe weld assembly 10 that the other end of straight bar section 31 is kink shape.
Further, the kink 32 of described wear indicator 30 is " 5 " font, and the afterbody of kink 32 is connected with straight bar section 31, head is concordant with the profile line of brake shoe weld assembly 10.She Ji benefit is like this, when the straight bar section 31 of wear indicator 30 rubs with the Brake drum wheel hub, because the effect of frictional force, straight bar section 31 can have a spot of deformation space, prevent the damage of wear indicator 30, simultaneously also Wear indicator 30 and the violent friction of Brake drum wheel hub cause the wearing and tearing of Brake drum wheel hub.The head of kink 32 and the profile line of brake shoe weld assembly 30 be concordant can make be connected between wear indicator 30 and the brake shoe weld assembly 10 more firm.
Further, described wear indicator 30 forms for the tabular stainless steel material bending of bar.Stainless steel material had both had certain rigidity, also have certain elasticity, can satisfy the force request of wear indicator 30, stainless steel also has electric conductivity simultaneously, can by sensor alarm signal be passed to the automobile ECU control system with electrical signal transfer to sensor.
