Abstract
The utility model discloses a feedback-type automobile disc brake, and the disc brake comprises brake calipers, a brake disc, an axle part, and an oil cylinder. The axle part is connected with the brake calipers and the brake disc. The brake calipers are inverted U-shaped. The brake disc extends into the brake calipers. The brake calipers at two sides of the brake disc are respectively provided with a brake lining block which is connected with a piston. The pistons and the oil outlet of the oil cylinder are connected through hydraulic oil channels disposed between the pistons and the oil outlet of the oil cylinder. The inverted U-shaped bending part of the brake calipers is provided with a pressure sensor. The top of each brake lining block is provided with a pressure plate. The pressure sensor is electrically connected with an ECU of an automobile. The disc brake provided by the utility model feeds back the wear degree of the brake lining blocks, and reduces the hidden trouble of braking.
Description
Technical field
The utility model relates to automobile brake field, especially relates to a kind of reaction type automotive disc brake.
Background technique
Disc type brake has the advantages such as Braking efficiency height and perfect heat-dissipating because of it, be applied to more and more widely in Modern Car.But automobile frequently braking can make the position of friction brake disk on break wear and tear gradually, cause braking ability to decline, there is great potential safety hazard.
As Chinese patent notice of authorization number: CN2784666, in the patent document of on 05 31st, 2006 notice of authorization day, a kind of opposite open type hydraulic direct-driven caliper disc brake is disclosed, it comprises oil cylinder, piston and seal ring, oil cylinder is in body, piston is contained in oil cylinder, oil cylinder is connected with supplying oil circuit by hydraulic fluid port, between oil cylinder and piston, seal ring is housed, this break is made up of two bodies, each body upper, downside is all equipped with a pair of pressing plate, pin is housed on pressing plate, pin and upper, friction lamellar body is housed between press table, on friction lamellar body, there is friction plate, between friction lamellar body and press table, elasticity spacer is housed, friction lamellar body base plate face is close on piston exterior edge face, two bodies are fastened on bearing by screw rod symmetry, brake disc is between two friction plates.Its volume is little, and braking force is large, due to the effect of elasticity spacer; make friction plate in stationary state, therefore can adjust very easily the gap between friction plate and brake disc, and more renewal of facing renewal is also convenient and swift; reduce dead time, improved working efficiency.But also there is a problem, after the friction disc wear on break, be inconvenient to discover, lack feedback and warning.
Model utility content
The utility model is to be difficult for discovering, lacking the deficiency of feeding back in order to overcome the existing automobile brake friction plate degree of wear, and a kind of reaction type automotive disc brake that can detect friction plate abrasion degree is provided.
To achieve these goals, the utility model is by the following technical solutions:
A kind of reaction type automotive disc brake of the present utility model, comprise brake caliper, brake disc, vehicle bridge portion and oil cylinder, vehicle bridge portion connects brake caliper and brake disc, brake caliper is inverted U-shaped, brake disc stretches in brake caliper, on the brake caliper of brake disc both sides, be respectively provided with a brake shoe, brake shoe is connected with piston, between the oil outlet of piston and oil cylinder, hydraulic oil channel being set is connected, the inverted U-shaped crooked position of brake caliper is provided with pressure transducer, brake shoe top is provided with pressing plate, the pressure transducer automobile ECU that is electrically connected.
When braking, the fuel-displaced promotion piston driving of the oil cylinder brake shoe on brake caliper clamps brake disc, thereby makes car deceleration by the friction of brake shoe and brake disc.Advancing of brake shoe advanced pressing plate, and the pressure that pressure transducer is received is with the front of brake shoe and then increase.Before and after brake-pad wear, same braking, the pressure that pressure transducer is subject to is different, feeds back to automobile ECU with this, obtains brake-pad wear information, reminds car owner to change in time brake shoe.
As preferably, described hydraulic oil channel is located in brake caliper, and hydraulic oil channel is inverted U-shaped.Reasonable Arrangement hydraulic oil channel, saves break space.
As preferably, on the brake petal of automobile, displacement transducer is set, the displacement transducer automobile ECU that is electrically connected.Displacement transducer is set on brake petal, reference standard is provided, make, before and after brake-pad wear, same braking to be obtained to prerequisite relatively.Wearing and tearing by stress reaction brake shoe are more accurate.
The utlity model has following beneficial effect: the degree of wear of regenerative braking pad in time, reduces brake safe hidden danger.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure: brake caliper 1, brake disc 2, vehicle bridge portion 3, brake shoe 4, piston 5, oil outlet 6, hydraulic oil channel 7, pressure transducer 8, pressing plate 9.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
In embodiment as shown in Figure 1, a kind of reaction type automotive disc brake, comprises brake caliper 1, brake disc 2, vehicle bridge portion 3 and oil cylinder, and vehicle bridge portion 3 connects brake caliper 1 and brake disc 2, and brake caliper 1 is inverted U-shaped, and brake disc 2 stretches in brake caliper 1.On the brake caliper 1 of brake disc 2 both sides, be respectively provided with a brake shoe 4, brake shoe 4 is connected with piston 5, between the oil outlet 6 of piston 5 and oil cylinder, hydraulic oil channel 7 is set and is connected.Hydraulic oil channel 7 is located in brake caliper 1, and hydraulic oil channel 7 is inverted U-shaped.The inverted U-shaped crooked position of brake caliper 1 is provided with pressure transducer 8, and pressure transducer 8 is specially the rear telescopic pressure transducer of contact.Brake shoe 1 top is provided with pressing plate 9, pressure transducer 8 automobile ECU that is electrically connected.On the brake petal of automobile, displacement transducer is set, the displacement transducer automobile ECU that is electrically connected.
When braking, the fuel-displaced promotion piston 5 of oil cylinder on brake caliper 1 drives brake shoe 4 to clamp brake disc 2, thereby makes car deceleration by brake shoe 4 and the friction of brake disc 2.Advancing of brake shoe advanced pressing plate, and the pressure that pressure transducer 8 is received is with the front of brake shoe 4 and then increase.Before and after brake-pad wear, by the displacement transducer record on brake petal relatively, the pressure that pressure transducer is subject to is different, feeds back to automobile ECU with this, obtains brake-pad wear information, reminds car owner to change in time brake shoe.
