Technical Field
The utility model belongs to the technical field of automobile parts, and particularly relates to a low-slip-resistance low-cost brake caliper body for a new energy automobile.
Background
In an automobile brake system, a brake caliper is used as an actuating element of a brake terminal, and generally, a piston is pushed by hydraulic pressure or air pressure, and then the piston pushes a friction plate to press a brake disc, so that the braking purpose is realized by friction force. As a single-side piston structure, the floating brake caliper is widely applied due to the advantages of simple structure, low cost, convenience in maintenance and the like.
The floating brake caliper is composed of a fixed caliper frame and a floating caliper body, the caliper frame is fixed on a steering knuckle through a bolt, the caliper body is connected with a guide pin into a whole through a caliper body fastening bolt, and is inserted into a guide hole in the caliper frame through the guide pin and moves in the direction of a hole core in the guide hole, and the caliper body and the guide pin synchronously slide. When the automobile brakes, the piston pushes the friction plate on one side to move, when the friction plate contacts the brake disc, the caliper body moves towards the direction far away from the disc surface of the brake disc, and the friction plate on the opposite side of the piston on the caliper body moves towards the side where the disc surface of the brake disc is located until the friction plates on the two sides of the brake disc are abutted against the disc surfaces on the two sides of the brake disc, so that the purpose of braking is achieved.
At present, a guide pin in an automobile brake caliper is in clearance fit with a guide hole in a caliper body, lubricating grease is also injected into the guide hole to reduce friction force in order to ensure that the caliper body can freely slide on the guide pin, and the influence of sliding resistance on the performance of the caliper, such as drag torque and the like, is large, and the influence on the endurance of a new energy automobile is large. The developed product is shown in fig. 1, and comprises a caliper body a1, wherein support lugs a13 on two sides of the caliper body a1 are connected with guide pins through locking bolts, the guide pins are connected with caliper body brackets, the caliper body a1 comprises an oil inlet hole a11 and an air bleeding screw hole a12, each support lug a13 is in a horizontal structure and is connected with a connecting seat a14, the gravity center a of the caliper assembly in the structure is located between the upper end face of a connecting seat a14 of the caliper body a1 and an installation face of an executing structure, namely the gravity center a is located inside a hole depth center plane i-i of a connecting hole on the connecting seat a14 and has a proper interval, and the unstable position of the gravity center a can cause the caliper body a1 and the executing mechanism A3 to generate overturning moment around the support lug a13, so that the guide pins cannot move smoothly during each braking, thereby increasing sliding resistance and affecting the performance of the caliper.

Detailed Description
First, it should be noted that the meanings of the directions of the inside, the outside, the front, the rear, and the like are that the inside and the outside are in the vehicle width direction, the vehicle middle part is the inside, the vehicle outside is the outside, when the brake caliper is arranged at the upper position of the brake disc, the brake caliper body is deviated from the side where the vehicle head is located to be the front, otherwise, the brake caliper assembly is arranged on the brake disc 1 as shown by combining the rear with fig. 2.
As shown in fig. 3 to 4, the low-sliding-resistance brake caliper for the new energy automobile comprises a caliper body 10, the caliper body 10 is connected with an execution unit 30 inside the caliper body 10 through a connecting bolt 20, lugs 13 arranged at the front end and the rear end inside the caliper body 10 are connected with a guide pin 50 through a locking bolt 40, the guide pin 50 is connected with a caliper body bracket 60, the guide pin 50 is placed in a guide hole in the caliper body bracket 60, and the caliper body 10 comprises an oil inlet hole 11 and an air outlet screw hole 12, and is characterized in that: the end of each support lug 13 is connected with a connecting seat 14, a hole depth center plane I-I of a connecting hole on the connecting seat 14 is closely adjacent to the gravity center A of a brake caliper assembly formed by the brake caliper body 10, the execution unit 30 and the caliper body bracket 60, and each support lug 13 extends forwards and backwards and inwards in an arc-shaped claw shape, and more preferably, the support lugs are closely adjacent to each other until being overlapped.
In the above-described embodiment, hole depth center plane i-i of the connection hole in connection holder 14 indicates the center position in the hole length direction, and therefore may be understood as a plumb surface on which the thickness center line of connection holder 14 in the vehicle width direction is located. Because the machining error inevitably exists, the probability of superposition of the two parts is very small, the two parts are arranged close to each other as far as possible, and the overturning moment is very small because the moment arm is very small. The utility model can effectively avoid generating overturning moment during braking, the return of the brake caliper body 10 is smoother during braking, the sliding resistance is reduced, and the performance of the brake caliper assembly is improved.
As shown in fig. 3 and 4, each of the lugs 13 extends forward and backward and inward in an arc-shaped claw shape. When the scheme is adopted, the position relation between the assembly surface between the execution unit 30 and the brake caliper body 10 and the installation position between the brake caliper body 10 and the caliper body bracket 60 is adjusted, so that the hole depth central plane I-I of the connecting hole on the connecting seat 14 is favorably adjacent to or coincided with the gravity center A of the brake caliper assembly formed by the brake caliper body 10, the execution unit 30 and the caliper body bracket 60.
The actuating unit 30 is connected to the connecting support 15 on the inner end surface between the two lugs 13 of the caliper body 10 by symmetrically arranged connecting bolts 20. The actuator 30 is an actuator of the electronic parking brake system.
When the brake caliper body 10 is designed, the position of the support lug 13 of the brake caliper body 10 in the vehicle width direction is adjusted by measuring the gravity center position of the brake caliper assembly through software, and the caliper body bracket 60 is developed in a matching manner, so that the position of the gravity center A of the brake caliper assembly is ensured to be close to or overlapped with the hole depth center plane I-I of the connecting hole on the connecting seat 14.
